Comparative total mortality in 25 years in Italian and Greek middle aged rural men. (1/19464)

STUDY OBJECTIVE: Mortality over 25 years has been low in the Italian and very low in the Greek cohorts of the Seven Countries Study; factors responsible for this particularity were studied in detail. PARTICIPANTS AND SETTINGS: 1712 Italian and 1215 Greek men, aged 40-59 years, cohorts of the Seven Countries Study, representing over 95% of the populations in designated rural areas. DESIGN: Entry (1960-61) data included age, systolic blood pressure (SBP), smoking habits, total serum cholesterol, body mass index (BMI), arm circumference, vital capacity (VC), and forced expiratory volume in 3/4 seconds (FEV); the same data were obtained 10 years later. Multivariate Cox analysis was performed with all causes death in 25 years as end point. MAIN RESULTS: Italian men had higher entry levels of SBP, arm circumference, BMI, and VC; Greek men had higher cholesterol levels, smoking habits, and FEV. Mortality of Italian men was higher throughout; at 25 years cumulative mortality was 48.3% and 35.3% respectively. Coronary heart disease and stroke mortality increased fivefold in Italy and 10-fold in Greece between years 10 and 25. The only risk factor with a significantly higher contribution to mortality in Italian men was cholesterol. However, differences in entry SBP (higher in Italy) and FEV (higher in Greece) accounted for, according to the Lee method, 75% of the differential mortality between the two populations. At 10 years increases in SBP, cholesterol, BMI, and decreases in smoking habits, VC, FEV, and arm circumference had occurred (deltas). SBP increased more and FEV and VC decreased more in Italy than in Greece. Deltas, fed stepwise in the original model for the prediction of 10 to 25 years mortality, were significant for SBP, smoking, arm circumference, and VC in Greece, and for SBP and VC in Italy. CONCLUSION: Higher mortality in Italian men is related to stronger positive effects of entry SBP and weaker negative (protective) effects of FEV; in addition 10 year increases in SBP are higher and 10 year decreases in FEV are larger in Italy. Unaccounted factors, however, related to, for example, differences in the diet, may also have contributed to the differential mortality of these two Mediterranean populations.  (+info)

The amyloid precursor protein interacts with Go heterotrimeric protein within a cell compartment specialized in signal transduction. (2/19464)

The function of the beta-amyloid protein precursor (betaAPP), a transmembrane molecule involved in Alzheimer pathologies, is poorly understood. We recently reported the presence of a fraction of betaAPP in cholesterol and sphingoglycolipid-enriched microdomains (CSEM), a caveolae-like compartment specialized in signal transduction. To investigate whether betaAPP actually interferes with cell signaling, we reexamined the interaction between betaAPP and Go GTPase. In strong contrast with results obtained with reconstituted phospholipid vesicles (Okamoto et al., 1995), we find that incubating total neuronal membranes with 22C11, an antibody that recognizes an N-terminal betaAPP epitope, reduces high-affinity Go GTPase activity. This inhibition is specific of Galphao and is reproduced, in the absence of 22C11, by the addition of the betaAPP C-terminal domain but not by two distinct mutated betaAPP C-terminal domains that do not bind Galphao. This inhibition of Galphao GTPase activity by either 22C11 or wild-type betaAPP cytoplasmic domain suggests that intracellular interactions between betaAPP and Galphao could be regulated by extracellular signals. To verify whether this interaction is preserved in CSEM, we first used biochemical, immunocytochemical, and ultrastructural techniques to unambiguously confirm the colocalization of Galphao and betaAPP in CSEM. We show that inhibition of basal Galphao GTPase activity also occurs within CSEM and correlates with the coimmunoprecipitation of Galphao and betaAPP. The regulation of Galphao GTPase activity by betaAPP in a compartment specialized in signaling may have important consequences for our understanding of the physiopathological functions of betaAPP.  (+info)

Allyl-containing sulfides in garlic increase uncoupling protein content in brown adipose tissue, and noradrenaline and adrenaline secretion in rats. (3/19464)

The effects of garlic supplementation on triglyceride metabolism were investigated by measurements of the degree of thermogenesis in interscapular brown adipose tissue (IBAT), and noradrenaline and adrenaline secretion in rats fed two types of dietary fat. In Experiment 1, rats were given isoenergetic high-fat diets containing either shortening or lard with or without garlic powder supplementation (8 g/kg of diet). After 28 d feeding, body weight, plasma triglyceride levels and the weights of perirenal adipose tissue and epididymal fat pad were significantly lower in rats fed diets supplemented with garlic powder than in those fed diets without garlic powder. The content of mitochondrial protein and uncoupling protein (UCP) in IBAT, and urinary noradrenaline and adrenaline excretion were significantly greater in rats fed a lard diet with garlic powder than in those fed the same diet without garlic. Other than adrenaline secretion, differences due to garlic were significant in rats fed shortening, also. In Experiment 2, the effects of various allyl-containing sulfides present in garlic on noradrenaline and adrenaline secretion were evaluated. Administration of diallyldisulfide, diallyltrisulfide and alliin, organosulfur compounds present in garlic, significantly increased plasma noradrenaline and adrenaline concentrations, whereas the administration of disulfides without allyl residues, diallylmonosulfide and S-allyl-L-cysteine did not increase adrenaline secretion. These results suggest that in rats, allyl-containing sulfides in garlic enhance thermogenesis by increasing UCP content in IBAT, and noradrenaline and adrenaline secretion.  (+info)

The food matrix of spinach is a limiting factor in determining the bioavailability of beta-carotene and to a lesser extent of lutein in humans. (4/19464)

Carotenoid bioavailability depends, amongst other factors, on the food matrix and on the type and extent of processing. To examine the effect of variously processed spinach products and of dietary fiber on serum carotenoid concentrations, subjects received, over a 3-wk period, a control diet (n = 10) or a control diet supplemented with carotenoids or one of four spinach products (n = 12 per group): whole leaf spinach with an almost intact food matrix, minced spinach with the matrix partially disrupted, enzymatically liquefied spinach in which the matrix was further disrupted and the liquefied spinach to which dietary fiber (10 g/kg wet weight) was added. Consumption of spinach significantly increased serum concentrations of all-trans-beta-carotene, cis-beta-carotene, (and consequently total beta-carotene), lutein, alpha-carotene and retinol and decreased the serum concentration of lycopene. Serum total beta-carotene responses (changes in serum concentrations from the start to the end of the intervention period) differed significantly between the whole leaf and liquefied spinach groups and between the minced and liquefied spinach groups. The lutein response did not differ among spinach groups. Addition of dietary fiber to the liquefied spinach had no effect on serum carotenoid responses. The relative bioavailability as compared to bioavailability of the carotenoid supplement for whole leaf, minced, liquefied and liquefied spinach plus added dietary fiber for beta-carotene was 5.1, 6.4, 9.5 and 9.3%, respectively, and for lutein 45, 52, 55 and 54%, respectively. We conclude that the bioavailability of lutein from spinach was higher than that of beta-carotene and that enzymatic disruption of the matrix (cell wall structure) enhanced the bioavailability of beta-carotene from whole leaf and minced spinach, but had no effect on lutein bioavailability.  (+info)

Improvement of factor VII clotting activity following long-term NCPAP treatment in obstructive sleep apnoea syndrome. (5/19464)

Obstructive sleep apnoea syndrome (OSAS) is a very common disorder. Patients with OSAS are at an increased risk for cardiovascular events. It has also been reported that a 25% rise in factor VII clotting activity (FVIIc) is associated with a 55% increase in ischaemic heart disease death during the first 5 years. We examined the effects of nasal continuous positive airway pressure (NCPAP) treatment on FVIIc in patients with OSAS. FVIIc was investigated prospectively in 15 patients with OSAS before (mean +/- SEM apnoea and hypopnoea index (AHI) 61.5 +/- 4.2 and after (AHI 3.0 +/- 0.9) NCPAP treatment for immediate relief, at 1 month after treatment and at over 6 months. FVIIc levels gradually decreased after NCPAP treatment. After 6 months of NCPAP treatment, FVIIc levels had decreased significantly (before 141.1 +/- 11.7% vs. after 6 months 110.7 +/- 6.2%; p < 0.01). Six of the seven patients whose FVIIc levels were over 140% before the NCPAP treatment had FVIIc levels below 130% after 6 months or 1 year of NCPAP treatment. This decrease in FVIIc after long-term NCPAP treatment could improve mortality in OSAS patients. If patients, especially obese ones, present with high FVIIc of unknown origin, it would be prudent to check for OSAS.  (+info)

Gallstones: an intestinal disease? (6/19464)

Current evidence suggests that impaired intestinal motility may facilitate gallstone formation by influencing biliary deoxycholate levels or by modulating interdigestive gall bladder motility (fig 2), although a primary intestinal defect in gallstone pathogenesis has not yet been demonstrated. In the cold war period, most interesting events, from a political point of view, occurred at the border between capitalist and communist systems, near the iron curtain. Similarly, the gall bladder and biliary tract can be viewed as the border between liver and intestinal tract, where many interesting things occur with profound impact on both systems. Combined efforts by researchers in the field of hepatology and gastrointestinal motility should brake down the Berlin wall of ignorance of one of the most common diseases in the Western world.  (+info)

Chlamydia pneumoniae antibodies are associated with an atherogenic lipid profile. (7/19464)

OBJECTIVE: To determine, within a representative population group of men and women, whether alteration of the lipid profile might underlie the reported association between Chlamydia pneumoniae and ischaemic heart disease. DESIGN AND SETTING: Cross sectional survey in an area with a high incidence of ischaemic heart disease. SUBJECTS: 400 randomly selected participants in the World Health Organisation MONICA project's third population survey in Northern Ireland. MAIN OUTCOME MEASURES: Stored sera were examined by microimmunofluorescence for IgG antibodies to C pneumoniae at a dilution of 1 in 64. Mean total and high density lipoprotein (HDL) cholesterol were compared between seropositive and seronegative individuals with adjustment for age, measures of socioeconomic status, smoking habit, alcohol consumption, body mass index, and the season during which blood had been taken. RESULTS: In seropositive men, adjusted mean serum total cholesterol and HDL cholesterol were 0.5 mmol/l (9.2%) higher and 0.11 mmol/l (9.3%) lower, respectively, than in seronegative men. Differences in women did not achieve statistical significance, but both total cholesterol and HDL cholesterol were higher (3.6% and 5.8%, respectively) in seropositive than in seronegative individuals. CONCLUSIONS: There is serological evidence that C pneumoniae infection is associated with an atherogenic lipid profile in men. Altered lipid levels may underlie the association between C pneumoniae and ischaemic heart disease.  (+info)

Chronic infection with Helicobacter pylori, Chlamydia pneumoniae, or cytomegalovirus: population based study of coronary heart disease. (8/19464)

OBJECTIVE: To study possible associations between coronary heart disease and serological evidence of persistent infection with Helicobacter pylori, Chlamydia pneumoniae, or cytomegalovirus. DESIGN: Population based, case-control study, nested within a randomised trial. SETTING: Five general practices in Bedfordshire, UK. INDIVIDUALS: 288 patients with incident or prevalent coronary heart disease and 704 age and sex matched controls. RESULTS: High concentrations of serum IgG antibodies to H pylori were present in 54% of cases v 46% of controls, with corresponding results for C pneumoniae seropositivity (33% v 33%), and cytomegalovirus seropositivity (40% v 31%). After adjustments for age, sex, smoking, indicators of socioeconomic status, and standard risk factors, the odds ratios (95% confidence intervals) for coronary heart disease of seropositivity to these agents were: 1.28 (0.93 to 1.75) for H pylori, 0.95 (0.66 to 1.36) for C pneumoniae, and 1.40 (0.96 to 2. 05) for cytomegalovirus. CONCLUSIONS: There is no good evidence of strong associations between coronary heart disease and serological markers of persistent infection with H pylori, C pneumoniae, or cytomegalovirus. To determine the existence of moderate associations between these agents and disease, however, larger scale studies will be needed that can keep residual confounders to a minimum.  (+info)

To our knowledge, there have been no previous studies on determining whether the baseline levels of remnant cholesterol qualified for a useful predictor independent of traditional prognostic variables for adverse outcomes. The main findings of the present study were summarized as follows. Firstly, according to Speamans correlation, remnant cholesterol was positively associated with major inflammatory biomarkers such as high sensitivity C-reactive protein, neutrophil count and fibrinogen (R 2 = 0.20, 0.12 and 0.14; P = 0.000, 0.036 and 0.010, respectively). Secondly, although remnant cholesterol was significantly correlated to serum triglyceride (R 2 = 0.832, P = 0.000), they did not show approximate relation to the Gensini scores (R 2 = 0075 vs. 0.115, P = 0.178 and 0.038 respectively). Thirdly, the ROC curve indicated a matchable discriminatory power of remnant cholesterol, HbA1C and Gensini scores for the cardiovascular outcomes in the study population (AUC for remnant cholesterol, HbA1C and ...

Diabetics often have elevated levels of serum lipids and cholesterol and increased risk of cardiovascular disease. Streptozotocin-induced diabetes was used to determine whether elevated serum cholesterol levels in diabetics are due to loss of control of hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase, which catalyzes the committed step in cholesterol synthesis. Strain A/ST female mice were fed 10% corn oil diets, half with 2% cholesterol. Experimental groups were injected with 9.0 mg streptozotocin / 100g body weight. Diabetes was confirmed by weight loss, elevated blood sugars, and enlarged spleens. Reductase activity was assayed spectrophotometrically. Serum cholesterol levels were determined by gas liquid chromatography. Both diabetic and control mice fed cholesterol had elevated serum cholesterol levels and decreased reductase activities. These observations suggest that HMG CoA reductase is not the primary control point in the control of serum cholesterol levels in diabetic mice. The ...
High blood cholesterol is a leading risk factor in the development of atherosclerosis and coronary heart disease (CHD) (1,2). The risks associated with high blood cholesterol can be reduced by screening and early intervention (3). Current clinical practice guidelines provide evidenced-based standards for detection, treatment, and control of high blood cholesterol (4). Healthy People 2020 monitors national progress related to screening and controlling high blood cholesterol through the National Health Interview Survey and the National Health and Nutrition Examination Survey (NHANES). State-level estimates of self-reported cholesterol screening and high blood cholesterol prevalence are available using Behavioral Risk Factor Surveillance System (BRFSS) data. To assess recent trends in the percentage of adults aged ≥18 years who had been screened for high blood cholesterol during the preceding 5 years, and the percentage among those who had been screened within the previous 5 years and who were ...
We have been told for years that cholesterol levels being too high are problematic, that it can contribute to heart disease and strokes. In fact, this is true for many people.

What is cholesterol?. Cholesterol is a fatty substance that is found in the blood. Cholesterol is made naturally in the body, and is also introduced to the body through the foods you eat. Most people consider cholesterol to be a bad thing, but not all cholesterol is created equal. There is actually good and bad cholesterol. To have healthy cholesterol is to have enough or a higher amount of good cholesterol, and low bad cholesterol.. Good Cholesterol. HDL (high density lipids) is also known as good cholesterol. HDL cholesterol actually helps to clean blood vessels and transport bad cholesterol out of the body.. Foods that have good cholesterol include fish, avocado, oats, some nuts, and berries. These foods can help you raise your HDL cholesterol levels and lower the bad.. Bad Cholesterol. LDL, or low density lipids is bad cholesterol. This is the kind of cholesterol that creates plaque that can clog your blood vessels and create problems such as high blood pressure, stroke and heart ...
Pictured Recipe: Avocado Pesto. A. It depends. Most people absorb about half the cholesterol they consume through foods, but absorption rates vary (from 20 to 60 percent) from person to person. This variation may help explain why dietary cholesterol seems to increase levels of unhealthy LDL blood cholesterol in some people more than others, says EatingWell advisor Alice Lichtenstein.. In any case, saturated and trans fats have a bigger detrimental effect on blood cholesterol levels, and heart health in general, than dietary cholesterol does. Trans and saturated fats not only affect how much plaque is deposited in blood vessels, but also may damage the tissue of blood vessels, says Susan Moores, M.S., R.D., a spokesperson for the American Dietetic Association. With a few exceptions-notably eggs and shellfish-foods high in cholesterol, such as fatty meats and whole-milk dairy, also tend to be high in saturated fat. Cutting back on sources of saturated fat automatically limits intake of dietary ...

Cholesterol metabolism may be involved in pediatric gallstone disease. We aimed to reveal cholesterol metabolites and phytosterols and their relation to stone composition of sterols in children having black pigment and cholesterol stones. We performed retrospective controlled clinical study, in which we examined parameters of cholesterol metabolism and liver function values in serum (n = 28) and gallstones (n = 46) of consecutively cholecystectomized children. Serum values of age-, body mass index- and sex-matched children (n = 82) and adult gallstones (n = 187) served as controls. Surrogate markers of cholesterol synthesis in serum (squalene/cholesterol, cholestenol/cholesterol and lathosterol/cholesterol) were 26-52 % higher in both stone subclasses compared to controls (p | 0.05 for all). Respectively, cholestanol/cholesterol and plant sterols campesterol/cholesterol and sitosterol/cholesterol (cholesterol absorption markers) had decreasing order in serum: black pigment stone group | controls |
Table I shows, firstly, the mean total cholesterol concentration of each fifth of the distribution based on the original measurements in the cohort of 21 515 men (the group of 5696 men had the same original values); secondly, the mean total cholesterol concentration; thirdly, the mean low density lipoprotein cholesterol concentration of each fifth based on the repeat measurements in the group of 5696 men; and fourthly, the age adjusted death rates for ischaemic heart disease for the five groups. The threefold difference in mortality from ischaemic heart disease across the groups (1.11 to 3.11 deaths per 1000 man years) corresponded to a difference in original total cholesterol concentration of 3.1 (from 4.8 to 7.9) mmol/l but a smaller difference in repeat total cholesterol concentration of 2.2 (5.0 to 7.2) mmol/l; this is the regression dilution bias. The threefold difference in mortality from ischaemic heart disease corresponded to an even smaller difference in low density lipoprotein ...
In the past 20 years, serum cholesterol levels have decreased markedly in eastern Finland. Our results demonstrate that the entire cholesterol distribution shifted substantially toward lower values. The population-based strategy applied was also effective in markedly reducing the proportion of high-risk individuals with high cholesterol levels. It is obvious that the high-risk approach alone would not have been appropriate in eastern Finland in the 1970s. Depending on the chosen cutoff point for cholesterol alone, half or more of the middle-aged population should have been considered as high-risk individuals in the early 1970s. Applying individual intervention, including pharmacological therapy, would have been difficult to implement, if not impossible, and intolerably expensive. Also, the cholesterol-lowering drugs available at that time were not optimal,16 and even today, we have only limited information on their long-term efficacy and safety in the prevention of CHD in healthy ...
Cholesterol is a type of fat in the blood. It is needed for many body functions, such as making new cells. Cholesterol is made by the body and also comes from food your child eats. High cholesterol means your child has too much of this type of fat in his or her blood.. There are two types of cholesterol: LDL and HDL. LDL is the bad cholesterol that builds up inside the blood vessel walls, making them too narrow. This reduces the flow of blood and can cause a heart attack or stroke. HDL is the good cholesterol that helps clear bad cholesterol from the body.. High cholesterol can be caused by eating food with too much saturated fat or cholesterol in it or by being overweight. It can also run in families.. High cholesterol has no symptoms. You may first find out that your child has high cholesterol when your childs doctor does a routine cholesterol test. ...

A study published in the American Journal of Medical Genetics Part B (Neuropsychiatric Genetics) has found that a small subgroup of children with ASD have abnormally low cholesterol levels (hypocholesterolemia), leading researchers to believe cholesterol may play a role in the cause of some cases of the disorder. The childrens low cholesterol levels were apparently due to a limited ability to make cholesterol. Nineteen of the 100 children who participated in the study were found to have total cholesterol levels below 100 mg/dL, which is lower than that found in 99 percent of children. The average cholesterol level for children between 4 and 19 years of age is 165 mg/dl. The study authors found evidence that the low cholesterol levels were caused by a reduced ability of the body to naturally produce cholesterol, and not by inadequate amounts of cholesterol in the diet or gastrointestinal problems that interfere with cholesterol absorption, two of the more common causes of low blood cholesterol ...

These healthy choices can lower high cholesterol, and they may even end up preventing diabetes.. If your doctor has told you that you have high cholesterol levels, it may be time to take action. Having high total or bad LDL cholesterol or low good HDL cholesterol can increase risk for heart attacks and stroke, but the condition is usually treatable. Therapeutic lifestyle changes, such as diet and exercise, are the first line of defense, while medications may be necessary to lower higher levels of cholesterol or for patients who cannot lower cholesterol when they make lifestyle changes.. The following strategies can help lower high total cholesterol, LDL cholesterol, and/or triglycerides, and/or raise HDL cholesterol. As you will see, many of these choices can also help prevent diabetes if you have prediabetes or slightly high blood sugar, and Lark DPP can help you establish these choices as healthy habits.. ...
With all the news and warnings about the dangers of high cholesterol, many people view cholesterol as a “bad†substance that should be eliminated completely from our lives. In truth, cholesterol serves some important functions in the body. In order to understand how cholesterol affects the body, one must first understand what cholesterol is.. Cholesterol is a waxy substance that is attached to the fats in our bloodstream and is present in all of the cells of the body. Cholesterol comes from food that we eat, as well as being manufactured directly by the liver. Cholesterol is an important regulator in the bloodstream, as it helps to regulate the formation of many cells as well as hormones. However, to have too high or too low of a cholesterol count in the blood can be a very dangerous factor, often leading to a heart attack or a stroke. Although cholesterol is prevalent in the blood stream, it cannot dissipate in the blood. The cholesterol maneuvers throughout the body attached to ...
The main new results of the present study were that: (I) BPS and CS subgroups had enhanced cholesterol synthesis, (II) in the BPS group, solely serum squalene of the surrogate markers of cholesterol synthesis was logically (inversely) related to those of cholesterol absorption, (III) the children with CS had low absorption of cholesterol, (IV) their homeostatic regulation of cholesterol metabolism was intact and (V), in the CS group, serum non-cholesterol sterols reflected their own proportions in the stone content.. Hepatic hypersecretion of biliary cholesterol with formation of cholesterol crystals from cholesterol supersaturated bile is considered to be the crucial phenomenon in the pathogenesis of the CS [6]. In general, adult gallstone patients (predominantly with CS) have high synthesis of cholesterol parallel to increased biliary output of cholesterol, but relatively low intestinal cholesterol absorption, indicating enhanced whole-body sterol clearance [25]. Opposite to the clinical ...
Ivanhoe Newswire) -- It has been well-known that high levels of high-density lipoprotein (HDL) cholesterol, the good kind, are associated with a lower risk of heart disease. Recent studies have asked if pharmacologic increases in HDL cholesterol levels are beneficial to the patient. A new study shows that a different metric, a measure of HDL function called cholesterol efflux capacity, is more closely associated with protection against heart disease than HDL cholesterol levels themselves.. Atherosclerosis typically occurs with a build-up of cholesterol along the artery wall. Cholesterol efflux capacity, an integrated measure of HDL function, is a direct calculation of the efficiency by which a persons HDL removes cholesterol from cholesterol-loaded macrophages (a type of white blood cell) -- the sort that accumulate in arterial plaque.. Recent scientific findings have directed increasing interest toward the concept that measures of the function of HDL, rather than simply its level in the ...
We are all aware that having too much cholesterol isnt good, so we tailor our diets when things begin to go awry with our health. But how much do you actually know about cholesterol and what it does to our bodies?. Cholesterol is an essential building block for the normal metabolism of the body. Cholesterol is a lipid (fat). The liver produces 90% of the bodys cholesterol (usually during sleep). This is primarily a genetic factor; only 10% comes from food. The problem is lipids cannot circulate alone in the blood stream because fat and water do not mix.. They require a transport system.. Water-soluble proteins called lipoproteins transport cholesterol in the blood, and the amount of lipoprotein determines how much cholesterol can be moved. There are three main types of lipoproteins that transport cholesterol:. HDL-high-density lipoprotein. Referred to as good cholesterol, because it removes cholesterol from arterial plaque and transports it back to the liver to be ...
Elevated Cholesterol May Deteriorate Bones Aside from high cholesterol increasing the risk of heart disease, new research suggests that it may also be bad for the bones. The study included 1303 postmenopausal women with higher levels of low-density lipoprotein (LDL)-the bad cholesterol-and showed that they were more likely to show signs of bone thinning, compared with women with normal cholesterol. Although the findings do not prove that high cholesterol is the reason for bone thinning, the results give a possible explanation for studies suggesting that statins protect bones, researchers reported in Obstetrics and Gynecology (November 2003). In the new study, women aged 45 to 65 who had gone through menopause had their bone density measured and cholesterol levels tested. The participants were separated into 3 groups based on LDL levels: normal (129 mg/dL), moderately high (130-150 mg/dL), and high (160 mg/dL and above). Women with high LDL levels were 74% more likely to have osteopenia, a ...
TY - JOUR. T1 - Cholesterol Metabolism: A Review of How Ageing Disrupts the Biological Mechanisms Responsible for its Regulation. AU - Morgan, AE. AU - Mooney, KM. AU - Wilkinson, SJ. AU - Pickles, NA. AU - Mc Auley, MT. PY - 2016/4/1. Y1 - 2016/4/1. N2 - Cholesterol plays a vital role in the human body as a precursor of steroid hormones and bile acids, in addition to providing structure to cell membranes. Whole body cholesterol metabolism is maintained by a highly coordinated balancing act between cholesterol ingestion, synthesis, absorption, and excretion. The aim of this review is to discuss how ageing interacts with these processes. Firstly, we will present an overview of cholesterol metabolism. Following this, we discuss how the biological mechanisms which underpin cholesterol metabolism are effected by ageing. Included in this discussion are lipoprotein dynamics, cholesterol absorption/synthesis and the enterohepatic circulation/synthesis of bile acids. Moreover, we discuss the role of ...
HMG CoA reductase inhibitors (statins) are commonly used to treat high cholesterol (HC) in both type 1 and type 2 diabetes mellitus (DM). Several studies have shown benefits of statin among patients of type 2 DM, however, no such data is available for patients with type 1 DM.. It is known from studies on cholesterol metabolism using surrogate markers that patients with type 1 DM have higher cholesterol absorption compared to normals and those with type 2 DM have higher cholesterol synthesis. Since statins inhibit synthesis, patients with type 1 DM may not have a good response and may respond better to cholesterol absorption inhibitors. The purpose of this study is to determine the cholesterol lowering effects of cholesterol absorption inhibitors and cholesterol synthesis inhibitors in subjects with type 1 and type 2 diabetes mellitus. ...
OBJECTIVE: To determine the quantitative importance of dietary fatty acids and dietary cholesterol to blood concentrations of total, low density lipoprotein, and high density lipoprotein cholesterol. DESIGN: Meta-analysis of metabolic ward studies of solid food diets in healthy volunteers. SUBJECTS: 395 dietary experiments (median duration 1 month) among 129 groups of individuals. RESULTS: Isocaloric replacement of saturated fats by complex carbohydrates for 10% of dietary calories resulted in blood total cholesterol falling by 0.52 (SE 0.03) mmol/l and low density lipoprotein cholesterol falling by 0.36 (0.05) mmol/l. Isocaloric replacement of complex carbohydrates by polyunsaturated fats for 5% of dietary calories resulted in total cholesterol falling by a further 0.13 (0.02) mmol/l and low density lipoprotein cholesterol falling by 0.11 (0.02) mmol/l. Similar replacement of carbohydrates by monounsaturated fats produced no significant effect on total or low density lipoprotein cholesterol. Avoiding
High blood cholesterol increases your risk of cardiovascular complications such as a heart attack or stroke. Your doctor may periodically evaluate your risk for these complications by using a calculator such as the Atherosclerotic Cardiovascular Disease Estimator. This calculator estimates your risk of having a heart attack or stroke in the next 10 years. It considers your total and good high-density lipoprotein (HDL) cholesterol levels, age, and systolic blood pressure. It also factors in whether you have diabetes, smoke, or use medicines to control high blood pressure. Your doctor will consider how unhealthy your blood cholesterol levels are and your 10-year risk calculation when deciding how best to treat your high blood cholesterol and to manage your risk of cardiovascular complications. Your doctor may recommend aspirin to prevent a first heart attack or stroke.. Keep in mind that this 10-year cardiovascular risk calculator may not accurately estimate risk in certain situations, such as ...
How is Non-High Density Lipoprotein abbreviated? NHDL stands for Non-High Density Lipoprotein. NHDL is defined as Non-High Density Lipoprotein rarely.
Cholesterol is a vital component of the human body. It stabilizes cell membranes and is the precursor of bile acids, vitamin D and steroid hormones. However, cholesterol accumulation in the bloodstream (hypercholesterolemia) can cause atherosclerotic plaques within artery walls, leading to heart attacks and strokes. The efficiency of cholesterol absorption in the small intestine is of great interest because human and animal studies have linked cholesterol absorption with plasma concentration of total and low density lipoprotein cholesterol. Cholesterol absorption is highly regulated and influenced by particular compounds in the food supply. Therefore, it is desirable to learn more about natural food components that inhibit cholesterol absorption so that food ingredients and dietary supplements can be developed for consumers who wish to manage their plasma cholesterol levels by non-pharmacological means. Food components thus far identified as inhibitors of cholesterol absorption include phytosterols,

TY - JOUR. T1 - Low and high density lipoproteins and chylomicrons as regulators of rate of cholesterol synthesis in rat liver in vivo. AU - Andersen, J. M.. AU - Turley, S. D.. AU - Dietschy, J. M.. PY - 1979/1/1. Y1 - 1979/1/1. N2 - The steady-state levels of plasma cholesterol carried in high and low density lipoproteins and in chylomicrons were varied over a wide range by use of a constant-infusion technique. After 40 hr, the rates of hepatic cholesterol synthesis and levels of hepatic cholesterol esters were measured and were related to the plasma level of each of the lipoprotein fractions. From the rates of infusion and the steady-state plasma levels attained, the whole animal clearance rates for cholesterol carried in low density and high density lipoproteins and in chylomicrons were calculated to be 0.53, 0.61, and 42.6 ml/hr, respectively. Hepatic cholesterol ester content increased by 0.8 μg/g for each 1.0 mg/dl increase in the steady-state level of plasma low density lipoprotein ...
Technically, there is no pure cholesterol in your bloodstream. Cholesterol is transported by lipoproteins. LDL (reduced-density lipoproteins) and HDL (high-density lipoprotiens) are the lipoprotiens utilised to transport cholesterol.. Tests can be run that really test for the cholesterol, which offers you the total cholesterol number (direct measurement). Or you can run a test for the HDL and LDL cholesterol complexes. You add these values to get a computed total cholesterol. If you run a total cholesterol AND calculate it from summing the HDL and LDL cholesterols they need to be close, but will not concur exactly. Tests have a margin of error. This is why they will not match exactly.. Though triglyerides are typically transported by lipoproteins, I do not know why they would use it to calculate total cholesterol.. We employed to run total cholesterol then and HDL, computing the LDL as a distinction among the total and HDL.. A correction to the answer above this - folic acid is not a fatty ...
Wouldnt it be great to find a natural, food-based way to end your high cholesterol woes?. Lets be clear: High cholesterol is generally a problem related to lifestyle and dietary choices.. Thats the best place to start making changes.. However, the following herbs and supplements are helpful because they may help keep your cholesterol levels manageable. Most herbs for high cholesterol are indirectly beneficial, helping to promote better blood circulation, which improves the bodys ability to remove cholesterol.. Consider the following options:. Garlic. A proven cholesterol emulsifier, garlic helps loosen cholesterol from artery walls. Garlic, in general, is highly beneficial, providing antibiotic, antiinflammatory, and anticancer benefits.. Green Tea. Research shows that green tea may increase high density lipoprotein (HDL) cholesterol (good cholesterol), and lower triglyceride and lower density lipoprotein (LDL) cholesterol (bad cholesterol). It has also been well documented that green ...
A cross-sectional study of a random sample of 976 coloureds (mixed race) of the Cape Peninsula, ages 15 to 64 years old, revealed a population with unexpectedly high levels of high density lipoprotein (HDL) cholesterol. The mean level for men was 55.4 +/- 16.1 mg/dl (SD) and for women, 60.8 +/- 16.0 mg/dl. The ratio of HDL cholesterol to total cholesterol expressed as a percentage was 26.3% +/- 9.5% for men and 28.1% +/- 9.3% for women. The HDL cholesterol levels were apparently lower than those of black and Negro populations, yet higher than those of Caucasian populations. Men with levels of HDL cholesterol above the median reported a personal history and a family history of coronary heart disease less frequently than did men with lower levels, while women with high levels of HDL cholesterol were less likely to have a history of hypertension or diabetes. Stepwise multiple regression analysis of variables significantly associated with HDL cholesterol levels showed that they explained 29.7% and ...

AU - Hartog, M. AU - Angelinetta, R. AU - Emmett, P. AU - Furniss, S. PY - 1977/8. Y1 - 1977/8. N2 - 1. (1) Seven healthy normolipaemic men aged 28-46 years (mean 33 years) were studied for four weeks on their usual diet, the mean polyunsaturated to saturated fat (P : S) ratio of which was approximately 0.23 and the cholesterol content 667 mg/day, and for four weeks on an isocaloric diet, containing similar proportions of protein, carbohydrate and fat, but with a mean P : S ratio of approximately 2.82 and a cholesterol content of 112 mg/day. 2. (2) Total serum cholesterol levels decreased by 18.7 ± 5.2% (mean ± SEM) on the polyunsaturated fat (PUF) diet. This was attributable to a similar reduction in serum low density lipoprotein (LDL) cholesterol. Serum very low density lipoprotein (VLDL) ...
Low saturated fat diets have been recommended as a means of reducing blood cholesterol levels for decades. However, for many years it has also been recognized that reducing the saturated fat content of the diet alone isnt sufficient to markedly lower blood cholesterol levels. To this point, since 2002, Dr. David Jenkins of the University of Toronto and his colleagues have published a series of studies showing that the combination of cholesterol-lowering foods called the portfolio diet lowers cholesterol to a much greater extent than any single food. Not surprisingly, soyfoods have been an integral part of this combination since they are low in saturated fat and soy protein itself lowers blood cholesterol levels. Subjects following the test diet are instructed to consume 22 grams of soy protein from soymilk, tofu and soy meat analogues per 1000 calories or about 35 grams per participant. Other components of the portfolio diet included nuts, soluble fiber and phytosterols.. In the latest study ...
For those who suffer from high cholesterol the best and first way to control and lower their cholesterol levels is through their diet. But many people are confused as to what constitutes a high cholesterol food they need to avoid and a low cholesterol food. This is because there is a difference between dietary cholesterol and blood cholesterol.. Generally most health guidelines recommend that dietary cholesterol not exceed 300 mg per day for most healthy people, but if one suffers from high LDL blood cholesterol levels then this intake should be not more than 200 mg per day.. Cholesterol, a waxy like substance, is only found in animal meat and tissues and its sources include red meat, eggs, fish, poultry, and dairy products. On the flip side any food derived from plant sources is cholesterol free, including high fat plants food sources such as avocados and peanut butter. This is where the confusion usually happens because eating large amounts of vegetable oil, which is virtually 100% food fat, ...

As we can see cholesterol performs vital functions in our body. However, there are two types of cholesterol, the good and the bad.. High-density lipoprotein cholesterol (HDL), is also known as good cholesterol. This form takes the excess from our blood and transports it to the liver so it can be removed from our body. (4). Then you have, low-density lipoprotein cholesterol (LDL), otherwise called bad cholesterol. It also transports cholesterol around the body to where it might be needed. However, as well as depositing it to repair cells it leaves excess cholesterol behind in the arteries. Very low density lipoprotein cholesterol (VLDL) is another bad form of cholesterol. When levels of this substance are high it can contribute to cardiovascular disease. Triglycerides are another fatty substance in our blood, in fact its the most common type of lipid (fat) in the body. Their role is to store excess energy we produce from our diet. VLDL is responsible for carrying triglycerides around ...

Cholesterol is a fatty substance produced by your liver. Its also found in foods high in saturated fat, such as meat, eggs, some shellfish, and whole-milk dairy products.. Your cells need some cholesterol to functional normally. But too much cholesterol in your blood can be harmful. High blood cholesterol levels can cause fatty deposits to build up on the walls of your arteries. This condition is known as atherosclerosis (sometimes called hardening of the arteries). Over time, the fatty deposits can decrease the amount of blood flowing in the arteries and eventually block blood flow entirely. This narrowing of the arteries can lead to heart disease, heart attack, and stroke. People who are overweight, eat a lot of foods high in saturated fat, or who have a family history of high cholesterol have an increased risk of high cholesterol levels. There are few symptoms of high cholesterol levels and a blood test is almost always needed to confirm it.. There are two kinds of cholesterol:. ...
Cellular cholesterol requirements are met by receptor mediated uptake of cholesterol in low density lipoprotein (LDL) particles andlor by endogenous synthesis, the rate limiting enzyme in the synthesis pathway being 3-hydroxy-3-methylglutary coenzyme A (HMG-CoA) reductase. Expressions of both the LDL receptor and HMG-CoA reductase genes are normally under end product repression by cellular cholesterol. Leukemic cells from patients with acute myelogenous leukemia (AML) have a higher receptor mediated uptake of LDL than normal white blood and nucleated bone marrow cells and the levels of plasma cholesterol are decreased in AML patients. Previous studies have also found that LDL is a promising drug carrier candidate for cytotoxic agents. Expression of the drug transporter protein P- glycoprotein (Pgp) causes the multidrug resistance phenotype and recent studies suggest that Pgp may be involved in cholesterol transport. The aims of the studies were to investigate the mechanisms behind elevated LDL ...

The idea that dietary cholesterol increases risk of coronary heart disease (CHD) by turning into blood cholesterol is compelling in much the same way that fish oil improves arthritis by lubricating our joints! Dietary cholesterol, chiefly in the form of eggs, has long been outlawed as a causative agent in CHD through its association with serum cholesterol. However, the scientific evidence to support a role for dietary cholesterol in CHD is relatively insubstantial in comparison with the incontrovertible link between its circulating blood relative in low density lipoprotein (LDL) cholesterol and CHD. Interpretation of the relationship between dietary cholesterol and CHD has been repeatedly confounded by an often inseparable relationship between dietary cholesterol and saturated fat. It has also been exaggerated by the feeding of unphysiologically high intakes of eggs. Nonetheless, numerous studies have shown that dietary cholesterol can increase serum LDL-cholesterol, but the size of this effect ...
Cholesterol absorption plays a key role in cholesterol homeostasis and understanding the lumenal events that play key roles in absorption remain poorly understood. The aims of the present study are fourfold: 1) To determine whether previously observed effects on cholesterol absorption during bile acid feeding are related to changes in pool size and intestinal transit or meal stimulated gall bladder emptying or plasma cholecystokinin levels. 2) To determine the effect of dietary sphingomyelin on cholesterol absorption, micellar solubilization and synthesis in normal adults and to assess the effects of intralumenal cholesterol solubilization, absorption and synthesis in adults with heterozygous mdr 3 deficiency (a defect leading to low biliary phospholipid content). 3) To determine the mechanism of action of a non-ionic detergent, Pluronic F-68, by evaluating its effect on cholesterol solubilization and distribution between micelles and vesicles, on cholesterol absorption and synthesis. 4) To ...
The main objective of the present work was to characterize the response of human cholesterol synthesis that occurs within the normal range of cholesterol intake. Our results demonstrate modestly reduced cholesterogenesis with increasing dietary cholesterol levels as assessed by two techniques. Metabolic responses to increased dietary cholesterol potentially include reduced endogenous synthesis, decreased absorption, and increased biliary excretion of cholesterol.7 35 Feedback inhibition of cholesterol synthesis has been well described in animals,20 21 whereas the results of investigations in humans have been somewhat equivocal, with downregulation reported in some6 7 35 36 37 38 39 but not all22 23 24 40 41 42 studies.

Cholesterol is a waxy, fat-like substance that is found in all cells of the body. Cholesterol enters the human body mainly through food [1], and the majority of the cholesterol in the body originates from the liver [2]. Cholesterol is required for the formation of sex hormones [3], Cholesterol can also be converted to bile acids in the liver and vitamin D in the skin and kidney [4] and the formation of bile acids that help the body to digest fat [5]. Many studies have reported the ability of different bacteria to reduce the cholesterol levels in aqueous systems, such as liquid media [6] and the blood serum [7].. Some bacteria not only utilize cholesterol as a sole carbon source [8] but also decompose cholesterol via the cholesterol oxidase enzyme (ChoX) and produce different intermediate compounds [9]. Enterococcus faecium CX and Lactobacillus acidophilus N5, which colonise the intestinal tract and survive under gastric conditions, assimilate cholesterol and reduce its level in serum [10]. ...

N2 - The importance of cholesterol ester synthesis by acyl CoA:cholesterol acyltransferase (ACAT) enzymes in intestinal and hepatic cholesterol metabolism has been unclear. We now demonstrate that ACAT2 is the major ACAT in mouse small intestine and liver, and suggest that ACAT2 deficiency has profound effects on cholesterol metabolism in mice fed a cholesterol-rich diet, including complete resistance to diet-induced hypercholesterolemia and cholesterol gallstone formation. The underlying mechanism involves the lack of cholesterol ester synthesis in the intestine and a resultant reduced capacity to absorb cholesterol. Our results indicate that ACAT2 has an important role in ...
Other researchers have since confirmed Ancel Keys square root relationship, adding that dietary cholesterol has greatest effects on serum cholesterol if it is added to a low cholesterol, or cholesterol-free diet. At moderate cholesterol intakes, serum cholesterol changed very little with added cholesterol. A 1997 meta-analysis compiled 9 predictive equations since 1990, calculating that for a 2500 kcal diet, a 1.37-2.68 mg/dl decrease in serum cholesterol could be expected for every 100 mg/day decrease in dietary cholesterol. The prediction based on their meta-analysis was a 2.2 mg/dl decrease in serum cholesterol for every 100 mg/day decrease in dietary cholesterol ...
Background: Prevention of coronary heart disease has included nationwide strategies to decrease blood lipid concentrations of New Zealanders. As the mean serum total cholesterol concentration of New Zealanders has decreased over time, these public health interventions appear to be somewhat successful. Time trends in young adults are useful to ascertain because at this age very few individuals take lipid-lowering medications, making the trends particularly informative on the effect of lifestyle changes. Time trends in triglyceride concentration have not been measured in New Zealanders. Objective: The goal of this research project was to describe time trends in plasma total cholesterol and triglyceride concentrations in samples of young adult New Zealanders from 1991 to 2013, and to compare time trends in total cholesterol concentration to national trends in those of a similar age and sex. Participants and Methods: Fasting plasma cholesterol and triglyceride concentrations of 2nd and 3rd year ...

With the well-established link between serum cholesterol levels and cardiovascular disease and the availability of effective cholesterol-lowering drugs, cholesterol screening has rapidly become a routine part of health care. Yet, much remains to be learned about how cholesterol levels are regulated at the cellular level (see the Perspective by Brown et al.). Now, Najafi-Shoushtari et al. (p. 1566, published online 13 May) and Rayner et al. (p. 1570, published online 13 May) have discovered a new molecular player in cholesterol control-a small noncoding RNA that, intriguingly, is embedded within the genes coding for sterol regulatory element-binding proteins (SREBPs), transcription factors already known to regulate cholesterol levels. This microRNA, called miR-33, represses expression of the adenosine triphosphate-binding cassette transporter A1, a protein that regulates synthesis of high-density lipoprotein (HDL, or good cholesterol) and that helps to remove bad cholesterol from the blood. ...
The average increase in high density lipoprotein concentrations of 3.99 mg/dl for an intake of 30 g of alcohol a day would be associated with a risk reduction of 13.5% (4.3% to 24.2%) among men in the physicians health study29; a similar reduction of 13.3% (10.6% to 15.9%) would be expected on the basis of results from the lipids research clinics study.32 If we adjust the effect estimate for intraindividual variability in high density lipoprotein cholesterol concentrations20 we estimate a 16.8% reduction in risk of coronary heart disease directly attributable to increased high density lipoprotein cholesterol concentration from consuming 30 g of alcohol a day Because the effect of alcohol on high density lipoprotein cholesterol concentration was stronger in those with lower baseline concentrations the predicted 5.09 mg/dl increase for those with an average concentration of 35 mg/dl would lower the risk of coronary heart disease by 20.9% after adjustment for intraindividual variability. Because ...
Triglycerides (TG)/high-density lipoprotein (HDL) cholesterol ratio is a marker of small/dense low-density lipoprotein particles, which are closely associated with various metabolic and vascular diseases. However, the role of TG/HDL cholesterol ratio in cerebrovascular diseases has not been well studied. In this study, we evaluated the relationship between TG/HDL cholesterol ratio and the presence of silent brain infarct (SBI) in a neurologically healthy population. We retrospectively evaluated consecutive participants in health check-ups between January 2006 and December 2013. SBI was defined as an asymptomatic, well-defined lesion with a diameter of ≥3 mm on T1- or T2-weighted images. TG/HDL cholesterol ratio was calculated after dividing absolute TG levels by absolute HDL cholesterol levels. Of 3172 healthy participants, 263 (8.3%) had SBI lesions. In multivariate analysis, TG/HDL cholesterol ratio was independently associated with SBI (adjusted odds ratio [aOR] = 1.16, 95% confidence interval [CI]

A key to effective treatment of cardiovascular disease is to understand the bodys complex lipoprotein transport system. Reverse cholesterol transport (RCT) is the process of cholesterol movement from the extrahepatic tissues back to the liver. Lipoproteins containing apoA-I [highdensity lipoprotein (HDL)] are key mediators in RCT, whereas non-high-density lipoproteins (non-HDL, lipoproteins containing apoB) are involved in the lipid delivery pathway. HDL particles are heterogeneous; they differ in proportion of proteins and lipids, size, shape, and charge. HDL heterogeneity is the result of the activity of several factors that assemble and remodel HDL particles in plasma: ATP-binding cassette transporter A1 (ABCA1), lecithin cholesterol acyltransferase (LCAT), cholesteryl ester transfer protein (CETP), hepatic lipase (HL), phospholipid transfer protein (PLTP), endothelial lipase (EL), and scavenger receptor class B type I (SR-BI). The RCT pathway consists of the following steps: 1. Cholesterol ...

The integrity of the cholesterol biosynthesis pathway is required for efficient African swine fever virus (ASFV) infection. We discovered that specific Rac1 inhibition impaired viral induced microtubule acetylation and viral intracellular transport. These findings highlight that viral infection is the result of a carefully orchestrated modulation of Rho family GTPase activity within the host cell; this modulation results critical for virus buy AMG517 morphogenesis and in turn, triggers cytoskeleton remodeling, such as microtubule stabilization for viral transport during early infection. INTRODUCTION The members of Rho family of small GTPases are essential key regulators of diverse critical cellular functions, including cytoskeleton dynamics, cell cycle progression, migration, the generation of reactive oxygen species, and gene expression (16, 29, 35, 53). Like the majority of Ras superfamily proteins, most Rho GTPases function as molecular switches and cycle between an active GTP-bound form and ...
In summary, our data indicate that SFV fusion and exit are highly cholesterol dependent, and that this sterol requirement is significantly reduced by the P226S mutation. Interestingly, preliminary data from our lab indicate that two independent mutants selected for cholesterol-independent growth also have the P226S mutation, supporting the importance of this region of the spike protein in the virus cholesterol requirement (Chatterjee, P., and M. Kielian, unpublished results). It is striking that although it is not conserved, the position analogous to SFV E1 P226 is not found as a serine residue in any of the alphavirus sequences in the database, including recent virus isolates from nature (Fig. 7). Other nonconserved proline residues in this and other E1 regions (eg., P237; Fig. 7) are present as a serine in some alphavirus sequences. Preliminary results with Sindbis virus, having alanine at position 226, indicate that both its infection and fusion are highly cholesterol dependent, similar to wt ...

In the present study, the relationship between exopolysaccharide production and cholesterol removal rates of five strains of Lactobacillus delbrueckii subsp. bulgaricus isolated from home-made yoghurt was studied. Test strains were selected according to their exopolysaccharide production capacity. Influence of different bile concentrations on cholesterol removal was investigated. It was confirmed that B3, ATCC 11842 and G11 strains which produce high amounts of exopolysaccharide (211, 200 and 159 mg/l, respectively) were able to remove more cholesterol from the medium compared to those that produce low amounts of exopolysaccharide (B2, A13). The highest cholesterol removal (31%) was observed by strain L. delbrueckii subsp. bulgaricus B3, producing a high amount of exopolysaccharide, in 3 mg/ml bile concentration. Cholesterol removal by resting and dead cells was investigated and it was found to be 4%-14% and 3%-10%, respectively. Cholesterol removal by immobilized and free cells of the B3 strain ...
Low cholesterol levels may have a big downside: severe depression, scientists say. A study of 260 men from the Netherlands shows those with chronically low cholesterol readings are more likely to suffer symptoms of severe depression. The study appears in the journal Psychosomatic Medicine. Researchers divided the 40- to 70-year-old men into those who had low cholesterol and those who maintained a slightly more moderate level. The study shows the relative risk of having severe depressive symptoms was four to seven times higher in the men with chronically low cholesterol levels. Researchers found no difference, however, in the levels of hostility or impulsiveness in either group. Recent weight loss and lower calorie intake also are associated with a higher risk of depressive symptoms, the researchers say. Dr. Diederick Grobbee, chairman of the Julius Center for Patient Oriented Research, University Medical Center, Utrecht, The Netherlands, says there are few studies in this area. He adds because ...
The primary cause of cardiovascular disease is atherosclerotic plaque formation. Sustained elevations of cholesterol in the blood increase the risk of cardiovascular disease. Lovastatin lowers hepatic cholesterol synthesis by competitively inhibiting HMG-CoA reductase, the enzyme that catalyzes the rate-limiting step in the cholesterol biosynthesis pathway via the mevalonic acid pathway. Decreased hepatic cholesterol levels causes increased uptake of low density lipoprotein (LDL) cholesterol and reduces cholesterol levels in the circulation. At therapeutic doses, lovastatin decreases serum LDL cholesterol by 29-32%, increases high density lipoprotein (HDL) cholesterol by 4.6-7.3%, and decrease triglyceride levels by 2-12%. HDL cholesterol is thought to confer protective effects against CV disease, whereas high LDL and triglyceride levels are associated with higher risk of disease ...
Natural News) Pectin, a soluble fiber usually found in fruits, can lower cholesterol levels, according to a review of studies published in the Journal of Nutrition & Intermediary Metabolism. The study review was carried out by researchers from Food Standards Australia New Zealand, and it comes in line with the thought that soluble fibers can lower blood cholesterol concentrations. (Related: 5 Healthy Snacks That Fight Heart Disease). In the review, the team used research databases like EMBASE, PubMed, and Cochrane CENTRAL to look for applicable studies. These included randomized controlled trials that lasted for at least two weeks and those that examined the increased intake of pectin added to foods or as a supplement, as well as those that report total cholesterol concentrations in non-acutely ill subjects. However, studies that examined mixtures of fibers or whole foods as their effects could not be attributed to pectin were excluded. Moreover, the quality of the studies was evaluated using ...
Maintaining normal cholesterol levels is critical for warding off heart disease. Proprotein convertase subtilisin kexin type 9 (PCSK9) is a major player in cholesterol regulation - mutations in this gene can lead to familial hypercholesterolemia, a genetic disorder characterized by abnormally high cholesterol levels and cardiovascular disease. Increased PCSK9 activity increases cholesterol levels by binding to low-density lipoprotein receptors (LDLR), which induces receptor degradation and the accumulation of low-density lipoproteins (LDL) in the bloodstream. Thus, high PCSK9 levels normally are associated with high cholesterol levels. However, a 16-week joint study by the University of Florida and Eli Lilly and Company used human volunteers to show that atorvastatin, a widely prescribed cholesterol-reducing drug, increases serum PCSK9 levels while lowering total cholesterol, triglycerides and LDL levels. This indicates that the relationship between PCSK9 and LDL serum levels are disrupted ...

Dietary analysis was made from interviews. The consumption of previous termsaturated fatnext term was found to be moderately high (30 per cent of calories), and of cholesterol low (mean 126 mg. per day). Of dietary factors, only cholesterol was positively correlated to a significant degree with serum cholesterol. The effect of dietary cholesterol was small, with 3 mg. per cent change in serum cholesterol per 100 mg. of change in dietary cholesterol. Relative body weight appeared to have more influence than dietary factors on serum cholesterol. Short periods of daily exercise had no significant effect on serum cholesterol levels. Dietary sugar was found to be negatively correlated with serum cholesterol. ...
This test measures the amount of very low-density lipoprotein (VLDL) in your blood.. VLDL cholesterol is a type of blood fat. Its considered one of the bad forms of cholesterol, along with LDL cholesterol and triglycerides. This is because high levels cholesterol can clog your arteries and lead to a heart attack. Sixty percent of a VLDL particle is a triglyceride, This test is usually used along with a series of other tests in a general lipid profile to screen for cardiovascular disease (CVD). High levels of VLDL cholesterol and triglycerides in your blood may mean you are at risk for CVD. People who are obese also have higher levels of VLDL cholesterol. ...

Consistent with a previous nested case-control study and with the recent observations on cholesterol-lowering statin drugs and prostate cancer, in the placebo arm of the PCPT, we observed that men with low serum cholesterol had a lower risk of high-grade prostate cancer. We did not observe associations between low cholesterol and total, organ-confined, or low-grade prostate cancer. We also extended the previous observations by showing that the association was restricted to the highest grade cases, Gleason 8 to 10. No association was observed between serum cholesterol and prostate cancer in the men randomized to finasteride. The plausibility that cholesterol may influence prostate cancer cell survival has been reviewed recently (23). Our findings add to the literature supporting a role for cholesterol in the etiology of prostate cancer with a worse prognosis.. There is a large literature indicating that low serum cholesterol is associated with a higher risk of all-cause cancer incidence and ...

Nascent HDL accepts unesterified cholesterol from peripheral tissues, esterified the free cholesterol and moves cholesterol ester to the core of HDL, then carries the cholesterol ester to liver for further metabolism. Therefore, HDL decreases the peripheral cholesterol deposition and reduces the risk for developing atherosclerotic diseases. In 1988 and 1993, both versions of the National Cholesterol Education Program in U.S.A. added HDL-Cholesterol (HDL-C) less than 35 mg/dL as a risk for coronary heart disease along with other risk factors such as diabetes and hypertension. The nutritionists in Taiwan often were ...
The influenza M2 protein not only forms a proton channel but also mediates membrane scission in a cholesterol-dependent manner to cause virus budding and release. The atomic interaction of cholesterol with M2, as with most eukaryotic membrane proteins, has long been elusive. We have now determined the cholesterol-binding site of the M2 protein in phospholipid bilayers using solid-state NMR spectroscopy. Chain-fluorinated cholesterol was used to measure cholesterol proximity to M2 while sterol-deuterated cholesterol was used to measure bound-cholesterol orientation in lipid bilayers. Carbon-fluorine distance measurements show that at a cholesterol concentration of 17 mol%, two cholesterol molecules bind each M2 tetramer. Cholesterol binds the C-terminal transmembrane (TM) residues, near an amphipathic helix, without requiring a cholesterol recognition sequence motif. Deuterium NMR spectra indicate that bound cholesterol is approximately parallel to the bilayer normal, with the rough face of the sterol

N2 - Cholesterol (a major component of brain membranes as well as of membrane microdomains called lipid rafts that are involved in the transduction of morphogenic signaling pathways) plays a pivotal role in fetal development and, in particular, brain development. Cholesterol levels in the brain are regulated through its biosynthesis and through its trafficking and elimination. Genetic syndromes caused by mutations in enzymes in the cholesterol biosynthesis pathways leading to reduced levels of cholesterol cause severe neurodevelopmental abnormalities, underscoring the importance of cholesterol during brain development. Additional neurodevelopmental disorders have been recently associated with altered ...
According to the lipid hypothesis, abnormally high cholesterol levels (hypercholesterolemia), or, more correctly, higher concentrations of LDL and lower concentrations of functional HDL are strongly associated with cardiovascular disease because these promote atheroma development in arteries (atherosclerosis). This disease process leads to myocardial infarction (heart attack), stroke and peripheral vascular disease. Since higher blood LDL, especially higher LDL particle concentrations and smaller LDL particle size, contribute to this process more than the cholesterol content of the LDL particles,[18] LDL particles are often termed bad cholesterol because they have been linked to atheroma formation. On the other hand, high concentrations of functional HDL, which can remove cholesterol from cells and atheroma, offer protection and are sometimes referred to colloquially as good cholesterol. These balances are mostly genetically determined but can be changed by body build, medications, food ...

A low plasma level of high-density lipoprotein (HDL) cholesterol (HDL-C) is associated with cardiovascular risk. A key cardioprotective property of HDL is cholesterol efflux capacity (CEC), the ability of HDL to accept cholesterol from macrophages. In this study, we aimed to identify the predictive value of CEC for cardiovascular risk. The relative risks (RRs) and 95% confidence intervals (CIs) were pooled to analyze the association between CEC and the incidence of cardiovascular events and all-cause mortality. The odds ratios (ORs) and 95% CIs were pooled to estimate the association of CEC and the prevalence of cardiovascular events. A total of 15 studies were included. Results showed that the highest CEC was significantly associated with a reduced risk of cardiovascular events incidents compared to the lowest CEC (RR, 0.56; 95% CI, 0.37 to 0.85; I 2, 89%); the pooled RR of cardiovascular risk for per unit SD increase was 0.87 (95% CI, 0.73 to 1.04; I

Cholesterol ester hydrolase (CEH) catalyses the rate limiting step in free cholesterol efflux from macrophage foam cells and intracellular CEH levels negatively correlate with lipid accumulation in foam cells and susceptibility to atherosclerosis. We have demonstrated that macrophage-specific transgenic expression of CEH enhances cholesterol efflux from foam cells and reduces lesions in athero-susceptible LDLR−/− mice. In the present study we tested the hypothesis that expression of CEH in blood-derived macrophages and the cholesterol efflux potential of serum from human subjects correlates with the disease status. Human subjects with (n=5, age 47-72 y) or without (n=7, age 50 -71 y) established CAD were enrolled. All subjects with established disease were on Statins and the serum lipid profiles (Total cholesterol, 198±16 vs 216±17; LDL-C, 109±13 vs 105±18; and HDL-C, 52±8 vs 63±10) were not significantly different between the two groups. Blood monocytes were isolated and cultured in ...
Previous reports have shown that cholesterol depletion of the membrane envelope of the hepatitis B virus (HBV) impairs viral infection of target cells. A potential function of this lipid in later steps of the viral life cycle remained controversial, with secretion of virions and subviral particles (SVP) being either inhibited or not affected, depending on the experimental approach employed to decrease the intracellular cholesterol level. This work addressed the role of host cell cholesterol on HBV replication, assembly, and secretion, using an alternative method to inhibition of the enzymes involved in the biosynthesis pathway. Growing HBV-producing cells with lipoprotein-depleted serum (LPDS) resulted in an important reduction of the amount of cholesterol within 24 h of treatment (about 40%). Cell exposure to chlorpromazine, an inhibitor of the clathrin-mediated pathway used by the low-density lipoprotein receptor for endocytosis, also impacted the cholesterol level; however, this level of inhibition
The primary mechanism of action appear to be a stimulation of bile acid synthesis and secretion, although how it does this is, as yet, unclear. A strong theory is that psyllium traps bile acid, instead of letting it be re-absorbed by the body, thereby requiring more to be produced. As cholesterol is the primary component bile acid, this may account for the lowering of measured cholesterol. It is also theorised that psyllium husk may increase production of an enzyme that breaks down cholesterol, known as cholesterol-7a-hydroxylase. Another potential mechanism of action is that as the fibre ferments in the colon, byproducts are absorbed that lower cholesterol synthesis in the liver and certain immune cells (peripheral blood mononuclear cells), although findings for that theory are inconsistent. Unlike food components such as phytosterols, psyllium husk has only a small effect on cholesterol absorption in the gut.. ...
Cholesterol, as commonly measured, doesnt say a lot about your risk of heart disease (HD). People with high cholesterol, low cholesterol, and everything in between die of heart disease. The high cholesterol leads to heart disease model does not explain those observations. A recent refinement to the model involves LDL/HDL size. Large light and fluffy LDL/HDL seems to REDUCE risk of CHD. While small, dense LDL/HDL INCREASES risk of HD. So what affects LDL/HDL size? Saturated fat seems to lead to LDL/HDL of increased size. Carbs, on the other hand, seem to lead to LDL/HDL of reduced size. Unexpected. Read Taubes book for more. So find out the size of your LDL/HDL before worrying. And read Gary Taubes book Good Calories, Bad Calories. Taubes does a superb job at exposing how research does not support common beliefs about heart disease, diabetes, and obesity.

The widespread use of children in cocoa production is controversial, not only for the concerns about child labor and exploitation, but also because up to 12,000 of the 200,000 children working in Côte d'Ivoire, the world's biggest producer of cocoa,[114] may be victims of trafficking or slavery.[115] Most attention on this subject has focused on West Africa, which collectively supplies 69 percent of the world's cocoa,[116] and Côte d'Ivoire in particular, which supplies 35 percent of the world's cocoa.[116] Thirty percent of children under age 15 in sub-Saharan Africa are child laborers, mostly in agricultural activities including cocoa farming.[117] Major chocolate producers, such as Nestlé, buy cocoa at commodities exchanges where Ivorian cocoa is mixed with other cocoa.[118] In 2009, Salvation Army International Development (SAID) UK stated that 12,000 children have been trafficked on cocoa farms in the Ivory Coast of Africa, where half of the world's chocolate is made.[119] SAID UK states ...

In the ad, a man is sitting in his living room directs a person in a chicken suit to behave in any way he wants. The tag line was "Chicken the way you like it." After the success of the Subservient Chicken, Burger King used the character in several subsequent advertising campaigns. In 2004, Burger King introduced the TenderCrisp Bacon Cheddar Ranch. The sandwich was promoted by a nationwide advertising campaign called Fantasy Ranch. The spot featured recording artist Darius Rucker (of Hootie and the Blowfish) singing a jingle to a tune reminiscent of "Big Rock Candy Mountain." The Chicken can be seen cavorting with some of the female dancers, including Vida Guerra, Brooke Burke and the Dallas Cowboys ...

George Washington pushed for the growth of hemp as it was a cash crop commonly used to make rope and fabric. In May 1765 he noted in his diary about the sowing of seeds each day until mid-April. Then he recounts the harvest in October which he grew 27 bushels that year. It is sometimes supposed that an excerpt from Washington's diary, which reads "Began to seperate [sic] the Male from the Female hemp at Do.&-rather too late" is evidence that he was trying to grow female plants for the THC found in the flowers. However, the editorial remark accompanying the diary states that "This may arise from their [the male] being coarser, and the stalks larger"[132] In subsequent days, he describes soaking the hemp [133] (to make the fibers usable) and harvesting the seeds,[134] suggesting that he was growing hemp for industrial purposes, not recreational. George Washington also imported the Indian hemp plant from Asia, which was used for fiber and, by some growers, for intoxicating resin production. In a ...

  • Cholesterol and protein traveling together are called lipoproteins. (
  • Cholesterol and protein traveling together are called lipoproteins (lie-poh-PRO-teenz). (
  • Cholesterol exists as small molecules in blood and is carried in packages called lipoproteins. (
  • Cholesterol is carried in the blood by proteins called lipoproteins. (
  • But too much cholesterol in the blood can clog the arteries that carry blood around your body. (
  • HDL (high-density lipoprotein) cholesterol , or "good cholesterol," doesn't clog arteries. (
  • Low-density lipoproteins, or "bad cholesterol," can build up on the walls of the arteries. (
  • High-density lipoproteins, or "good cholesterol," carry cholesterol away from the arteries and back to the liver. (
  • As cholesterol (plaque) builds up in the arteries, the arteries begin to narrow, which lessens or blocks the flow of blood. (
  • Too much LDL cholesterol in the blood can cause deposits of fats to build up in the walls of the arteries (atherosclerosis). (
  • LDL cholesterol builds up in the walls of your arteries, making them hard and narrow. (
  • VLDL and LDL are sometimes called "bad" cholesterols because they can contribute to the buildup of plaque in your arteries. (
  • Lowering your cholesterol may slow, reduce, or even stop the buildup of plaque in your arteries. (
  • High blood levels of cholesterol bound to a carrier molecule called a low-density lipoprotein (LDL) are associated with the formation of the plaques in arteries. (
  • High blood cholesterol levels can cause fatty deposits to build up on the walls of your arteries. (
  • Vytorin failed to halt the clogging of neck arteries better than Zocor alone, but it did a better job of reducing "bad" LDL cholesterol. (
  • Cholesterol wouldn't be nearly as dangerous without this process, which is thought to play an essential role in atherosclerosis, the hardening that occurs when low-density lipoprotein (LDL), also known as bad cholesterol, builds up in the arteries. (
  • When the level of LDL cholesterol goes up, excess cholesterol can build up and stick to the walls of your arteries . (
  • When too much LDL cholesterol is present, it begins to drop out of the blood and stick to the walls of the arteries. (
  • HDL picks up cholesterol off the walls of the arteries and takes it back to the liver where it can be broken down and removed. (
  • A build-up of cholesterol is part of the process that narrows arteries, called atherosclerosis . (
  • And that's because while our bodies need cholesterol, a waxy substance produced by the liver, to build cells, too much of the unwanted variety can build up in and clog arteries. (
  • Because high blood cholesterol has been associated with hardening of the arteries ( atherosclerosis ), heart disease, and a raised risk of death from heart attacks , cholesterol testing is considered a routine part of preventive healthcare. (
  • A high level of LDL cholesterol in the arteries can lead to a build-up within the walls leading to narrowing and blockages. (
  • While the "bad" low-density lipoprotein (LDL) cholesterol is widely blamed for clogging up the arteries and causing heart attacks, doctors in the documentary argue that it is wrong to see cholesterol (or saturated fats) as the villain of the piece. (
  • The extract significantly reduced the build-up of fatty deposits in arteries and blood cholesterol levels. (
  • Experiments have shown that compounds extracted from red wine and tea reduce cholesterol and lipid build-up in the arteries of rats," lead researcher Dr. Chau-Jong Wang told the BBC. (
  • The process of cholesterol buildup in arteries has been shown to begin during childhood. (
  • Plaques" are cholesterol deposits in the blood vessels and arteries. (
  • Unlike a lot of men, I don't have to worry about cholesterol -- that notorious clogger of arteries. (
  • LDL particles are involved in the formation of plaques (abnormal deposits of cholesterol) in the walls of the coronary arteries. (
  • LDL cholesterol is the "bad" type of cholesterol that can block your arteries - so a lower level is better for you. (
  • It helps clear LDL cholesterol out of your arteries, so a higher level is better for you. (
  • Evidence indicates that high density lipoproteins (HDL) prevents build up in the arteries and helps move the cholesterol through your body and to the liver for elimination. (
  • A cholesterol test can help determine your risk of the buildup of plaques in your arteries that can lead to narrowed or blocked arteries throughout your body (atherosclerosis). (
  • This is called the "good" cholesterol because it helps carry away LDL cholesterol, thus keeping arteries open and your blood flowing more freely. (
  • When free radicals come in contact with LDL cholesterol, they cause even more harm to arteries already damaged by plaque. (
  • If the cells already have enough then the cholesterol can build up in the arteries. (
  • This is because cholesterol can build up in the walls of the arteries (blood vessels pumping blood from the heart). (
  • The body needs some cholesterol to work properly but if there is too much in the blood , it can stick to the walls of the arteries . (
  • [1] Elevated LDL cholesterol levels can cause atherosclerosis, a condition in which cholesterol accumulates in the arteries and prevents the flow of oxygen-rich blood throughout the body. (
  • These findings cast dark clouds over what many scientists have long seen as the next-most promising avenue of cholesterol treatment after statin drugs, which slash the 'bad' cholesterol that accumulates in the arteries. (
  • Nissen headed a multi-center trial to see if the drug could reduce cholesterol buildup in arteries. (
  • LDL is often called bad cholesterol because of the role it plays in clogging arteries. (
  • It helps move cholesterol through your body and causes plaque to build up inside your arteries when present at high levels. (
  • The trial recruited people who were known to have cardiovascular disease due to the build-up of fatty material inside the arteries (atherosclerosis), or people with hereditary high cholesterol who are at higher risk of atherosclerosis. (
  • LDL (low-density lipoprotein) cholesterol , or "bad cholesterol. (
  • Meta-analyses have found that exercise results in small but significant decreases of low-density-lipoprotein- and total cholesterol (2), and that smoking is associated with a small, but significant higher concentration of these lipids (3). (
  • These foods may help prevent and manage high levels of low-density lipoprotein (LDL, or "bad") cholesterol and triglycerides while increasing high-density lipoprotein (HDL, or "good") cholesterol levels. (
  • Soy is also suggested to have an effect on plasma cholesterol, via increased plasma high-density lipoprotein cholesterol (HDL-C) and soy may also protect low density lipoprotein (LDL) from oxidation. (
  • This combination of proteins and cholesterol is called a lipoprotein. (
  • There are different types of cholesterol, based on what the lipoprotein carries. (
  • Lecithin cholesterol acyltransferase deficiency (LCAT deficiency) is a disorder of lipoprotein metabolism. (
  • Usually the enzyme produced is responsible for cholesterol ester formation and high density lipoprotein (HDL) metabolism, but in fish-eye disease the enzyme cannot esterify, or make the acid into an alkyl, cholesterol in HDL particles. (
  • Ivanhoe Newswire) -- It has been well-known that high levels of high-density lipoprotein (HDL) cholesterol, the "good" kind, are associated with a lower risk of heart disease. (
  • Low-density lipoprotein (LDL) is known as bad cholesterol. (
  • High-density lipoprotein (HDL) is known as good cholesterol. (
  • High-density lipoprotein, or HDL, is the good cholesterol. (
  • There are two types of carrier-cholesterol combinations, low-density lipoprotein (LDL) or "bad" cholesterol and high-density lipoprotein or "good" cholesterol. (
  • As part of a lipid profile (which includes other tests for high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides), it may also be used to monitor the effectiveness of treatment once it is initiated. (
  • Cholesterol traveling with a protein is called a lipoprotein. (
  • In tests, a team from the Chung Shan Medical University in Taiwan used rats to look at the effects of hibiscus extract on low-density lipoprotein, LDL, or "bad" cholesterol. (
  • People with diabetes have an increased risk of these diseases even if their 'bad' LDL-cholesterol (low-density lipoprotein) is "normal. (
  • LDL (low-density lipoprotein): Often called "bad" cholesterol because higher levels of LDL can increase the risk of heart disease. (
  • HDL (high-density lipoprotein): Often called "good" cholesterol because higher levels of HDL can reduce the risk of heart disease. (
  • Phytosterols and inulin added to soya milk has a more beneficial effect on low-density lipoprotein (LDL) cholesterol than soya milk alone, according to a study. (
  • A diet that combines cholesterol-lowering foods may results in greater decreases in low density lipoprotein (LDL) cholesterol levels than a low-saturated fat diet, according to new research. (
  • Some sources of cholesterol raise your high-density lipoprotein (HDL, or "good") cholesterol levels, while others raise your low-density lipoprotein (LDL, or "bad") cholesterol levels. (
  • This has left researchers grappling with a riddle: Low levels of high-density lipoprotein, or so-called good cholesterol, have long been shown as a predictor of heart disease, since HDLs help ferry bad cholesterol away from artery walls to the liver. (
  • High levels of low-density lipoprotein (LDL) cholesterol, or so-called 'bad' cholesterol, in the blood are a known risk factor for cardiovascular disease. (
  • Heterozygous patients have twice the normal blood levels of a particle called low-density lipoprotein, or LDL, which carries cholesterol in blood. (
  • LDL (low-density lipoprotein) is what most people think of as "bad cholesterol. (
  • HDL (high-density lipoprotein) is what most people think of as "good cholesterol. (
  • A study has looked into the safety of a new treatment to lower low-density lipoprotein (LDL), commonly known as "bad" cholesterol. (
  • Remnant cholesterol, also known as remnant lipoprotein, is a very atherogenic lipoprotein composed primarily of very low-density lipoprotein (VLDL) and intermediate-density lipoprotein (IDL). (
  • Too much alcohol can raise cholesterol levels and the levels of triglycerides , a type of fat in the blood. (
  • VLDL is similar to LDL cholesterol , but LDL mainly carries cholesterol to your tissues instead of triglycerides. (
  • A fasting blood test would then be used to test for Total Cholesterol, LDL (bad) cholesterol, HDL (good) cholesterol and Triglycerides. (
  • Just as with HDL and LDL cholesterol, your body makes triglycerides and also gets them from foods you eat. (
  • Question: Will fish oil lower triglycerides but increase bad cholesterol? (
  • Often triglycerides are reduced, and the HDL (good) cholesterol actually improves and LDL cholesterol decreases when fish oil supplementation is initiated. (
  • I recommend that your cholesterol (HDL and LDL) and triglycerides be monitored for changes when fish oil is added as a supplement for cardiac and vascular disease risk reduction. (
  • Labs can show higher total cholesterol, lower HDL 'good cholesterol', higher LDL 'bad cholesterol' and higher triglycerides. (
  • Another form of bad cholesterol is Triglycerides. (
  • Very low-density lipoproteins (VLDLs) carry mostly triglycerides, but they also contain 16-22% cholesterol. (
  • When your doctor talks about your cholesterol, they're actually talking about two types of cholesterol - HDL and LDL - along with triglycerides , which are a type of fat. (
  • When we refer to total cholesterol , it's a combination of HDL and LDL cholesterol plus triglycerides. (
  • Since triglycerides are part of the total cholesterol count, this means that if your triglycerides increase, your total cholesterol increases as well. (
  • First a bit about good and bad cholesterol and how triglycerides play a part in the cholesterol count. (
  • A complete cholesterol test - also called a lipid panel or lipid profile - is a blood test that can measure the amount of cholesterol and triglycerides in your blood. (
  • Cholesterol is measured using a blood test which shows the levels of LDL's, HDL's and triglycerides in the blood. (
  • Total blood cholesterol is the combined value of HDL, LDL, some triglycerides, and other fatty proteins in your blood. (
  • Hypertriglyceridemia is characteristic of high plasma remnant cholesterol, but persons with high plasma triglycerides without high remnant cholesterol rarely have coronary artery disease. (
  • Several types of medications are available for cholesterol lowering, including statins, bile acid sequestrants, niacin, and fibric acids. (
  • Statins have proven to be very effective and well-tolerated in most patients and are regarded as the treatment of choice for lowering 'bad' cholesterol levels. (
  • Statins work in the liver to interrupt the formation of cholesterol from the circulating blood. (
  • Do I really need to take statins for high cholesterol? (
  • Millions of Americans pop statins to keep their cholesterol levels down. (
  • Then, by making simple lifestyle changes such as eating a heart -healthy diet, exercising regularly, and taking cholesterol medications such as statins , if necessary, you can work your way toward that ratio. (
  • Dr. Suzanne Steinbaum, Preventive Cardiologist at Lenox Hill Hospital in New York City, joins UTTM to discuss the new guidelines focused on determining who should take cholesterol lowering drugs called statins. (
  • Statins are the gold standard in controlling your bad cholesterol and don't necessarily need to be considered only when diet and exercise have failed. (
  • Feb. 28, 2012 -- Memory loss, confusion, high blood sugar, and type 2 diabetes are possible side effects of the popular cholesterol-lowering drugs known as statins, the FDA warns. (
  • As part of a lipid profile, total cholesterol tests may be ordered at regular intervals to evaluate the success of lipid-lowering lifestyle changes, such as diet and exercise, or to determine the effectiveness of drug therapy such as statins . (
  • We also know that by the age of 40, as many as one in three of us will be taking cholesterol-lowering drugs called statins, to reduce our risk of coronary heart disease. (
  • Yet, with statins pushed as the answer, the cholesterol-lowering industry" is worth billions - the statin Lipitor made $13 billion for Pfizer in 2010. (
  • However, for people whose bodies naturally make large amounts of cholesterol, medications like statins may be the only way to decrease their cholesterol levels. (
  • Medications that lower cholesterol are called statins. (
  • HMG-CoA reductase inhibitors, commonly known as statins, are one class of drugs that lower blood cholesterol levels. (
  • Statins reduce the production of cholesterol by the liver by blocking an enzymatic reaction in the process of cholesterol synthesis. (
  • Controlling Cholesterol with Statins. (
  • Statins are a class of prescription drugs -- used together with diet and exercise -- to reduce the amount of low-density (LDL) cholesterol. (
  • 2. Statins work on cholesterol, both raising good and lowering bad, but have evil side-effects. (
  • Statins - This helps to block the enzyme in the liver which produces cholesterol. (
  • Previously, doctors had prescribed statins only as a way to lower cholesterol.The shift widens the use of statins for patients suffering from other health issues, like diabetes or heart disease. (
  • Based on the new guidelines, patients whose "bad" cholesterol tests in the "very high" range (190 and above) should be on statins. (
  • Now, people with cholesterol under 190 should not take statins unless they have other health issues, like diabetes or high blood pressure. (
  • Statins like Lipitor work by controlling the proteins in our liver that naturally produce cholesterol, a process that is regulated by the amount of cholesterol already in your blood. (
  • The problem with statins is that they don't impact cholesterol from eating animal products. (
  • They explain that even among patients who are already receiving optimal doses of statins, greater use of other, non-statin cholesterol-lowering drugs could help to further reduce cholesterol levels and potentially improve health outcomes for those most at risk. (
  • Though statins are first line treatment, it is clear from our contemporary study that statins alone even when optimally used will not help the majority of patients achieve European Society of Cardiology cholesterol goals. (
  • While diet and lifestyle are important factors in reducing LDL cholesterol, many patients are at increased risk - such as those with diabetes, inherited conditions or who have previously had heart attack or stroke - and are prescribed cholesterol-lowering drugs, like statins, to reduce their cholesterol. (
  • These treatments, such as ezetimibe, bempedoic acid, or PCSK9 inhibitors, can be used in combination with statins to further reduce LDL-cholesterol levels. (
  • Current guidelines from the European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) recommend statins as first-line treatment for lowering LDL cholesterol. (
  • However, among the patients receiving statins with a PCSK9 inhibitor about two thirds attained the new lower ESC recommended cholesterol goals. (
  • At a time when the now-ubiquitous cholesterol-lowering drugs called statins were yet to be discovered, his treatment over the next several years included a low-fat diet, cholestyramine (a drug that shunts excess cholesterol toward bile acid production), and nicotinic acid, which helps lower triglyceride fats. (
  • Researchers recruited over 2,000 people who were already taking statins to lower their cholesterol. (
  • This study adds to the research looking for new cholesterol-lowering treatments when statins either don't work or cause undesirable side effects. (
  • Statins are still the most well-established, effective treatment for bad cholesterol. (
  • The researchers wanted to see if adding bempedoic acid to the treatment regime of people who had high LDL cholesterol, despite receiving the maximum dose of statins, would help reduce LDL levels in the blood. (
  • It is highly unlikely that Benecol prevents coronary heart disease just because it lowers the cholesterol concentration as the combined results from eight ecological, four dynamic population, 41 cross- sectional, 25 cohort, and six case-control studies as well as a meta- analysis of nine, controlled, randomised trials strongly contradict an influence of dietary saturated and polyunsaturated fats on atherosclerosis or coronary heart disease (1). (
  • People with familial hypercholesterolaemia have high cholesterol from birth and are at high risk of developing atherosclerosis at a young age. (
  • These patients have low HDL cholesterol but surprisingly premature atherosclerosis is not seen. (
  • Atherosclerosis typically occurs with a build-up of cholesterol along the artery wall. (
  • Our growing understanding of inflammation's role in atherosclerosis doesn't diminish the importance of cholesterol -- you still have to keep that 'bad' number down and the 'good' number up -- but it does present another way to anticipate cardiovascular disease. (
  • More than 90% of adults surveyed are unaware of their cholesterol levels, or have never had their cholesterol levels tested, according to a multinational survey published by the European Atherosclerosis Society (EAS). (
  • Topics include cholesterol and atherosclerosis, risk factors for high cholesterol and heart disease, diagnosis and testing, and ways to improve cholesterol through diet, exercise, and medications. (
  • [2] That is true, but many people who exercise , eat fruits and vegetables, still have high cholesterol level, experience heart attacks, strokes , and even die, as the result of atherosclerosis. (
  • Atherosclerosis and the cholesterol issue are not equally pervading around the world. (
  • It is mostly Americans who care so much about cholesterol, yet atherosclerosis kills Americans by millions. (
  • Though more research is needed on the subject, it shows promising results in potentially preventing atherosclerosis in people with high cholesterol levels. (
  • Many of the foods that have cholesterol are also high in saturated and trans fats. (
  • Eating too much saturated fat or trans fats can result in unhealthy cholesterol levels. (
  • These fats are usually solid at room temperature and they are considered "bad" fats because they raise LDL cholesterol. (
  • Monounsaturated fats are "good" fats that help lower cholesterol levels. (
  • The National Institutes of Health's Medline site recommends the cholesterol-lowering TLC eating plan, which is similar to the better-known Mediterranean diet - with healthy fats, a bounty of veggies and lean proteins. (
  • However, foods that are rich is saturated fats are dangerous because when ingested the liver turns this fat into cholesterol. (
