By virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus, these compounds exhibit varying degree of antioxidant activity, depending on the site and number of methyl groups and the type of ISOPRENOIDS.
A nutritional condition produced by a deficiency of VITAMIN A in the diet, characterized by NIGHT BLINDNESS and other ocular manifestations such as dryness of the conjunctiva and later of the cornea (XEROPHTHALMIA). Vitamin A deficiency is a very common problem worldwide, particularly in developing countries as a consequence of famine or shortages of vitamin A-rich foods. In the United States it is found among the urban poor, the elderly, alcoholics, and patients with malabsorption. (From Cecil Textbook of Medicine, 19th ed, p1179)
A cobalt-containing coordination compound produced by intestinal micro-organisms and found also in soil and water. Higher plants do not concentrate vitamin B 12 from the soil and so are a poor source of the substance as compared with animal tissues. INTRINSIC FACTOR is important for the assimilation of vitamin B 12.
A nutritional condition produced by a deficiency of VITAMIN D in the diet, insufficient production of vitamin D in the skin, inadequate absorption of vitamin D from the diet, or abnormal conversion of vitamin D to its bioactive metabolites. It is manifested clinically as RICKETS in children and OSTEOMALACIA in adults. (From Cecil Textbook of Medicine, 19th ed, p1406)
A nutritional condition produced by a deficiency of VITAMIN B 12 in the diet, characterized by megaloblastic anemia. Since vitamin B 12 is not present in plants, humans have obtained their supply from animal products, from multivitamin supplements in the form of pills, and as additives to food preparations. A wide variety of neuropsychiatric abnormalities is also seen in vitamin B 12 deficiency and appears to be due to an undefined defect involving myelin synthesis. (From Cecil Textbook of Medicine, 19th ed, p848)
A nutritional condition produced by a deficiency of VITAMIN E in the diet, characterized by posterior column and spinocerebellar tract abnormalities, areflexia, ophthalmoplegia, and disturbances of gait, proprioception, and vibration. In premature infants vitamin E deficiency is associated with hemolytic anemia, thrombocytosis, edema, intraventricular hemorrhage, and increasing risk of retrolental fibroplasia and bronchopulmonary dysplasia. An apparent inborn error of vitamin E metabolism, named familial isolated vitamin E deficiency, has recently been identified. (Cecil Textbook of Medicine, 19th ed, p1181)

VITAMIN B 6 refers to several PICOLINES (especially PYRIDOXINE; PYRIDOXAL; & PYRIDOXAMINE) that are efficiently converted by the body to PYRIDOXAL PHOSPHATE which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, and aminolevulinic acid. During transamination of amino acids, pyridoxal phosphate is transiently converted into PYRIDOXAMINE phosphate. Although pyridoxine and Vitamin B 6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading (EE Snell; Ann NY Acad Sci, vol 585 pg 1, 1990). Most of vitamin B6 is eventually degraded to PYRIDOXIC ACID and excreted in the urine.

It is apparently synthesized in the liver and carries vitamin D and its metabolites through the circulation and mediates the response of tissue. It is also known as group-specific component (Gc). Gc subtypes are used to determine specific phenotypes and gene frequencies. These data are employed in the classification of population groups, paternity investigations, and in forensic medicine.
A nutritional condition produced by a deficiency of FOLIC ACID in the diet. Many plant and animal tissues contain folic acid, abundant in green leafy vegetables, yeast, liver, and mushrooms but destroyed by long-term cooking. Alcohol interferes with its intermediate metabolism and absorption. Folic acid deficiency may develop in long-term anticonvulsant therapy or with use of oral contraceptives. This deficiency causes anemia, macrocytic anemia, and megaloblastic anemia. It is indistinguishable from vitamin B 12 deficiency in peripheral blood and bone marrow findings, but the neurologic lesions seen in B 12 deficiency do not occur. (Merck Manual, 16th ed)

The 4-methanol form of VITAMIN B 6 which is converted to PYRIDOXAL PHOSPHATE which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid. Although pyridoxine and Vitamin B 6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading (EE Snell; Ann NY Acad Sci, vol 585 pg 1, 1990).
A group of substances similar to VITAMIN K 1 which contains a ring of 2-methyl-1,4-naphthoquinione and an isoprenoid side chain of varying number of isoprene units. In vitamin K 2, each isoprene unit contains a double bond. They are produced by bacteria including the normal intestinal flora.
A nutritional condition produced by a deficiency of THIAMINE in the diet, characterized by anorexia, irritability, and weight loss. Later, patients experience weakness, peripheral neuropathy, headache, and tachycardia. In addition to being caused by a poor diet, thiamine deficiency in the United States most commonly occurs as a result of alcoholism, since ethanol interferes with thiamine absorption. In countries relying on polished rice as a dietary staple, BERIBERI prevalence is very high. (From Cecil Textbook of Medicine, 19th ed, p1171)

Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.

The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Perspectives from micronutrient malnutrition elimination/eradication programmes. (1/904)

Micronutrient malnutrition cannot be eradicated, but the elimination and control of iron, vitamin A and iodine deficiencies and their health-related consequences as public health problems are currently the targets of global programmes. Remarkable progress is occurring in the control of goitre and xerophthalmia, but iron-deficiency anaemia (IDA) has been less responsive to prevention and control efforts. Subclinical consequences of micronutrient deficiencies, i.e. "hidden hunger", include compromised immune functions that increase the risk of morbidity and mortality, impaired cognitive development and growth, and reduced reproductive and work capacity and performance. The implications are obvious for human health and national and global economic and social development. Mixes of affordable interventions are available which, when appropriately adapted to resource availability and context, are proven to be effective. These include both food-based interventions, particularly fortification programmes, such as salt iodization, and use of concentrated micronutrient supplements. A mix of accompanying programmes for infection control, community participation, including education, communication and information exchange, and private sector involvement are lessons learned for overcoming deterrents and sustaining progress towards elimination.  (+info)

Candidate noninfectious disease conditions. (2/904)

Important micronutrient deficiencies in at-risk populations can be addressed simultaneously with programmatically cost-effective results. Because of the interaction between many micronutrients, this would also be biologically effective. With adequate investment and political support, the chances of eliminating iodine deficiency as a problem in women of reproductive age and young children and of eliminating vitamin A deficiency as a problem in young children in the future are high. To eliminate iron deficiency and folic-acid-dependent neural tube defects (FADNTDs) in low-income populations, a new set of approaches will have to be developed. These same approaches, if successful, could be used to tackle other important micronutrient deficiencies.  (+info)

Effect of iron-, iodine-, and beta-carotene-fortified biscuits on the micronutrient status of primary school children: a randomized controlled trial. (3/904)

BACKGROUND: Deficiencies of iron, iodine, and vitamin A are prevalent worldwide and can affect the mental development and learning ability of schoolchildren. OBJECTIVE: The aim of this study was to determine the effect of micronutrient-fortified biscuits on the micronutrient status of primary school children. DESIGN: Micronutrient status was assessed in 115 children aged 6-11 y before and after consumption of biscuits (fortified with iron, iodine, and beta-carotene) for 43 wk over a 12-mo period and was compared with that in a control group (n = 113) who consumed nonfortified biscuits. Cognitive function, growth, and morbidity were assessed as secondary outcomes. RESULTS: There was a significant between-group treatment effect on serum retinol, serum ferritin, serum iron, transferrin saturation, and urinary iodine (P <0.0001) and in hemoglobin and hematocrit (P <0.05). The prevalence of low serum retinol concentrations (<0.70 micromol/L) decreased from 39.1% to 12.2%, of low serum ferritin concentrations (<20 microg/L) from 27.8% to 13.9%, of anemia (hemoglobin <120 g/L) from 29.6% to 15.6%, and of low urinary iodine concentrations (<100 microg/L) from 97.5% to 5.4%. There was a significant between-group treatment effect (P <0.05) in cognitive function with the digit span forward task (short-term memory). Fewer school days were missed in the intervention than in the control group because of respiratory- (P = 0.097) and diarrhea-related (P = 0.013) illnesses. The intervention had no effect on anthropometric status [corrected]. CONCLUSIONS: Fortified biscuits resulted in a significant improvement in the micronutrient status of primary school children from a poor rural community and also appeared to have a favorable effect on morbidity and cognitive function [corrected].  (+info)

Using cost-effectiveness analysis to evaluate targeting strategies: the case of vitamin A supplementation. (4/904)

Given the demonstrated efficacy of vitamin A supplements in reducing childhood mortality, health officials now have to decide whether it would be efficient to target the supplements to high risk children. Decisions about targeting are complex because they depend on a number of factors; the degree of clustering of preventable deaths, the cost of the intervention, the side-effects of the intervention, the cost of identifying the high risk group, and the accuracy of the 'diagnosis' of risk. A cost-effectiveness analysis was used in the Philippines to examine whether vitamin A supplements should be given universally to all children 6-59 months, targeted broadly to children suffering from mild, moderate, or severe malnutrition, or targeted narrowly to pre-schoolers with moderate and severe malnutrition. The first year average cost of the universal approach was US$67.21 per death averted compared to $144.12 and $257.20 for the broad and narrow targeting approaches respectively. When subjected to sensitivity analysis the conclusion about the most cost-effective strategy was robust to changes in underlying assumptions such as the efficacy of supplements, clustering of deaths, and toxicity. Targeting vitamin A supplements to high risk children is not an efficient use of resources. Based on the results of this cost-effectiveness analysis and a consideration of alternate strategies, it is apparent that vitamin A, like immunization, should be provided to all pre-schoolers in the developing world. Issues about targeting public health interventions can usefully be addressed by cost-effectiveness analysis.  (+info)

Biochemical but not clinical vitamin A deficiency results from mutations in the gene for retinol binding protein. (5/904)

BACKGROUND: Two German sisters aged 14 and 17 y were admitted to the Tubingen eye hospital with a history of night blindness. In both siblings, plasma retinol binding protein (RBP) concentrations were below the limit of detection (<0.6 micromol/L) and plasma retinol concentrations were extremely low (0.19 micromol/L). Interestingly, intestinal absorption of retinyl esters was normal. In addition, other factors associated with low retinol concentrations (eg, low plasma transthyretin or zinc concentrations or mutations in the transthyretin gene) were not present. Neither sibling had a history of systemic disease. OBJECTIVE: Our aim was to investigate the cause of the retinol deficiency in these 2 siblings. DESIGN: The 2 siblings and their mother were examined clinically, including administration of the relative-dose-response test, DNA sequencing of the RBP gene, and routine laboratory testing. RESULTS: Genomic DNA sequence analysis revealed 2 point mutations in the RBP gene: a T-to-A substitution at nucleotide 1282 of exon 3 and a G-to-A substitution at nucleotide 1549 of exon 4. These mutations resulted in amino acid substitutions of asparagine for isoleucine at position 41 (Ile41-->Asn) and of aspartate for glycine at position 74 (Gly74-->Asp). Sequence analysis of cloned polymerase chain reaction products spanning exons 3 and 4 showed that these mutations were localized on different alleles. The genetic defect induced severe biochemical vitamin A deficiency but only mild clinical symptoms (night blindness and a modest retinal dystrophy without effects on growth). CONCLUSIONS: We conclude that the cellular supply of vitamin A to target tissues might be bypassed in these siblings via circulating retinyl esters, beta-carotene, or retinoic acid, thereby maintaining the health of peripheral tissues.  (+info)

Dietary antioxidants and magnesium in type 1 brittle asthma: a case control study. (6/904)

BACKGROUND: Type 1 brittle asthma is a rare form of asthma. Atopy, psychosocial factors and diet may contribute to this condition. As increased dietary magnesium has a beneficial effect on lung function and selenium, vitamins A, C and E have antioxidant properties, a study was undertaken to test the hypothesis that patients with brittle asthma have diets deficient in these nutrients compared with subjects with non-brittle asthma and healthy adults. METHODS: A case control study of the dietary intakes of 20 subjects with brittle asthma, 20 with non-brittle asthma, and 20 healthy adults was performed using five day weighed dietary records. Intake of magnesium was the primary outcome measure with selenium and vitamins A, C and E as secondary outcomes. Serum levels were measured at the same time as the dietary assessment. RESULTS: Sixty subjects (27 men) of mean age 49.5 years were recruited and completed the study. Subjects with brittle asthma had statistically lower median dietary intakes of vitamins A and E than the other groups (vitamin A: brittle asthma 522.5 micrograms/day, non-brittle asthma 869.5 micrograms/day, healthy adults 806.5 micrograms/day; vitamin E: brittle asthma 4.3 mg/day, non-brittle asthma 4.6 mg/day, healthy adults 4.5 mg/day). Median dietary intakes for the other nutrients were not significantly different between groups. Serum levels were within normal ranges for each nutrient in all subjects. Intakes less than the reference nutrient intake (RNI) for magnesium and vitamins A and C, and less than the safe intake (SI) for vitamin E were more likely in patients with brittle asthma than in those with non-brittle asthma. CONCLUSION: Nutrient deficiency and reduced antioxidant activity may contribute to disease activity in type 1 brittle asthma, although a prospective study of replacement therapy will be needed to confirm this hypothesis.  (+info)

Ocular signs and symptoms and vitamin A status in patients with cystic fibrosis treated with daily vitamin A supplements. (7/904)

BACKGROUND/AIMS: Patients with cystic fibrosis (CF) may have low plasma vitamin A levels from malabsorption, zinc deficiency, liver disease, or poor compliance with prescribed supplements. In view of the increasing number of adults with CF, many of whom drive cars, it is important to assess vitamin A status. In our centre an attempt has been made to achieve normal levels of fat soluble vitamins by annual estimation of plasma levels and appropriate oral supplementation. This study aimed to determine if this approach prevents vitamin A deficiency and the consequent problems with dark adaptation. METHODS: The study was conducted at the regional adult and paediatric cystic fibrosis unit and the patients were recruited from there. Dark adaptation studies were conducted at the department of ophthalmology, St James's University Hospital. All patients are regularly seen in the outpatient department by a CF specialist dietitian and have a comprehensive annual dietary assessment. 28 patients had the following investigations: serum retinol, plasma zinc, serum retinol binding protein, liver function tests, dark adaptation, contrast sensitivity, and anterior ocular surface status. 25 age and sex matched controls without CF or ocular pathology were also recruited for the dark adaptation study. RESULTS: None of the patients had vitamin A deficiency, the median value of serum retinol being 48 microg/dl, range 31-80 microg/dl (normal range 30-80 microg/dl). Dark adaptation was normal in all cases compared with the control group where the mean value was 3.4 log units of threshold luminance (95% confidence interval 2.4-4.0). None of the test group had a value of threshold luminance 2 SD above the mean value for the control group. Eight patients had reduced contrast sensitivity. The median value for serum zinc was 14.2 micromol/ l, range 13-81 micromol/l (normal range 8-23 micromol/l) and the median value for retinol binding protein was 36 mg/l, range 13-81 mg/l (normal range 35-58 mg/l). There was no correlation between dark adaptation and serum retinol, zinc, or retinol binding protein. Two patients had clinical evidence of dry eye. CONCLUSION: Regular estimates of plasma vitamin A together with appropriate supplementation and expert dietetic review can maintain normal dark adaptation in patients with cystic fibrosis. The occurrence of reduced contrast sensitivity function is well documented but remains an unexplained phenomenon and deserves further study.  (+info)

Parenteral vitamin requirements during intravenous feeding. (8/904)

Serum vitamin levels of 40 patients undergoing parenteral nutrition over a 5-to 42-day period were studied while the subjects received daily water-soluble and once weekly fat soluble vitamin formulations intravenously. Initial serum deficiencies of vitamins A, C, and folate were noted in a large portion of the severely malnourished population. At the replacement levels used in this study a small number of patients developed subnormal levels of vitamins A and D. Improvement in levels for vitamin C and folate were noted for most patients. Vitamin B12 deficiencies were not noted in any patient. Currently available commercial vitamin preparations can be used with safety in the parenterally nourished population and recommended guidelines for weekly infusion of both water and fat soluble vitamins are presented.  (+info)

Vitamins and minerals are essential to life. They act as cofactors or prosthetic groups for most enzymes, thus making biochemical reactions possible. Some cofactors are transiently associated with a given enzyme and in this capacity they function as cosubstrates. They are also called coenzymes. Besides being cofactors for enzymes some vitamins such as the fat-soluble vitamins A and D have been shown to exhibit hormone-like functions. Thus, vitamin A and its metabolites retinaldehyde and retinoic acids are involved in the growth, differentiation and maintenance of epithelial tissues as well as for reproduction. Retinoic acids can substitute for vitamin A--deficient animals in growth promotion and epithelial differentiation. As for vitamin D is interesting to note that the skin is both the site of vitamin D3 and 1,25-dihydroxy vitamin D3 synthesis and a target organ for the latter. 1,25 (OH)2 vitamin D3 is essential for mineral homeostasis and bone integrity as well as the regulation of growth and ...

Vitamin A deficiency leads to altered lipid metabolism in the liver. The expression pattern of metabolic genes in vitamin A-sufficient (VAS) versus vitamin A-deficient (VAD) liver was compared using a Mouse Genome Oligo Set Version 3.0 (Qiagen-Operon) 70mer-oligonucleotide array. Results from microarray analysis were analyzed using the GeneSpring bioinformatics program. The microarray results were further confirmed by real-time PCR. Mice were made vitamin A deficient by placing them on the modified AIN-93G diet without vitamin A on the tenth day of gestation. Both the differential expression of metabolic genes and the metabolic outcome of this differential expression were assessed. ^ In this study, vitamin A deficiency caused a decrease in expression of genes encoding enzymes involved in mitochondrial β-oxidation, including fatty acid ligase, medium-chain acyl-CoA dehydrogenase, 3,2-trans-enoyl-CoA isomerase and carnitine o-palmitoyl transferase I in the liver. A decrease in the mitochondrial β
Full Text - Objective: The current study evaluated the relationship between circulating fat soluble vitamin status and cognition in aging Chinese population.Methods: A cross-sectional study was carried out in 1754 community residents aged 55-80 years aiming to evaluate the relationship between circulating α-tocopherol and retinol status and cognition. The effect of ApoE genetic polymorphism on the relationship between vitamins and cognition was also explored.Results: Our results indicated that serum retinol status positively correlated with cognitive performance; while, serum α-tocopherol (α-TOH)/retinol ratio negatively correlated with cognitive performance. Mild cognitive impairment (MCI) subject demonstrated higher serum α-TOH status (P < 0.05), α-TOH/retinol ratio (P < 0.01) and lower retinol status (P < 0.01) than normal subjects. Subjects with ApoE4 genotype have lower serum retinol level (P < 0.05) and higher α-TOH/retinol ratio (P < 0.01)

Vitamin A deficiency, which affects about 100 million young children worldwide, was long known to cause blindness. But it has become increasingly clear that even mild vitamin A deficiency also impairs the immune system, reducing childrens resistance to diarrhoea, which kills 2.2 million children a year, and measles, which kills nearly 1 million annually. And new findings strongly suggest that vitamin A deficiency is a cause of maternal mortality as well, especially among women in impoverished regions (Panel 1).. At its most basic level, malnutrition is a consequence of disease and inadequate dietary intake, which usually occur in a debilitating and often lethal combination. But many more elements -- social, political, economic, cultural -- are involved beyond the physiological.. Discrimination and violence against women are major causes of malnutrition.. Women are the principal providers of nourishment during the most crucial periods of childrens development, but the caring practices vital to ...

Youve all probably heard the idea that stress causes health problems. Your doctor may have even told you that your health concern(s) exist solely because of stress. In my opinion - thats pretty close to nonsense. Its a great excuse though. Why? Stress doesnt cause poor health. OK, Ill be flexible with you. Severe, unrelenting physical (major accident, etc.), chemical (acute exposure to a massive dose of a toxin, etc.) or emotional ((un)expected death, etc.) stressors can actually cause health problems. Im also willing to say that long-term unresolved stressors can also cause health problems. But then again, its not necessarily the stress thats causing the problem if its that long-term (referring to behavioral patterns). There could be an emotional component to why the long-term stressor has not been resolved. Either way, those instances are fortunately not the norm. With that in mind, I find most of the time its not the stressor that is the problem, its how the body handles the ...

TY - JOUR. T1 - Cloning of rat cytochrome P450RAI (CYP26) cDNA and regulation of its gene expression by all-trans-retinoic acid in vivo. AU - Wang, Y.. AU - Zolfaghari, R.. AU - Catharine, Ross A.. PY - 2002/5/15. Y1 - 2002/5/15. N2 - A novel retinoic acid (RA)-inducible cytochrome P450 (P450 RAI or CYP26), previously cloned from human, zebra fish, and mouse, functions in the metabolism of all-trans-RA to polar metabolites including 4-hydroxy-RA and 4-oxo-RA. To further study CYP26 in the rat model, we first cloned rat CYP26 cDNA. The nucleotide sequence predicts a 497-amino-acid protein whose sequence is 95% identical to mouse and 91% homologous to human CYP26. Animal studies showed that CYP26 mRNA expression is very low (0.01 ± 0.008; P , 0.05) in vitamin-A-deficient rats compared to pair-fed vitamin-A-sufficient rats (defined as 1.0). In a kinetic study, vitamin-A-deficient rats were treated with ∼ 100 μg of all-trans-RA and liver was collected after 3-72 h for analysis of CYP26 mRNA by ...
This blinded randomised trial has shown that oral supplementation of vitamin A in a dose of 5000 IU/day did result in an increase in plasma retinol concentrations but did not decrease the incidence of CLD in preterm infants of less than 1000 g birth weight. In addition, mortality and the incidence of other complications such as ROP, IVH, NEC, and PDA were unaffected by vitamin A supplementation. The results of this study of oral supplementation are in contrast with previous studies, which used intramuscular supplementation of vitamin A and showed a significant decrease in the incidence of oxygen dependency at 1 month of age and/or death.6-12 Although most of these studies were performed before the routine use of antenatal steroids and postnatal surfactant, the most recent study was performed after the introduction of these important interventions, which may influence the incidence of CLD.6 This study is the first randomised controlled trial of oral vitamin A supplementation, and it has been ...
Hi everyone! This is Jeffery Smith and Im reporting on the news development that the Department of Agriculture in the Philippines has approved genetically engineered golden rice to be, As safe as conventional rice. . What a disaster this is! This is incredible! Now, a lot of people think that golden rice is the example of why we should be allowing genetically engineered foods into the diet because its designed to provide vitamin A for vitamin A-deficient children who are suffering from blindness and death. On the cover of TIME magazine, they say This rise could save the lives and health of, you know, thousands or millions of children each year. Well, this is all false hype. Lets go through this and find out the truth behind GE golden rice. First of all, rice is a staple in parts of Asia and other places. So we are considering genetically engineering something that will be eaten three times a day. If theres any health issue associated with it, it could be a disaster. Now, the Philippines ...

Vitamin A palmitate 1.5MIU/g is the Corrective Vitamin otherwise known as Retinol Palmitate or Retinyl Palmitate. Retinyl palmitate can be used as an additive in skin care formulations or can be applied directly onto the skin. After its absorption into the skin, retinyl palmitate is converted to retinol, and ultimately to retinoic acid (the active form of vitamin A present in Retin-A). Only retinoids such as retinoic acid have a direct effect on skin and can adjust to help the skin achieve a more youthful look.. ...
The third goal specified in the contract is perhaps the most important. It addresses the important planning question of what we should expect in a new programme in a new setting. The response can be divided into two sub-questions: in what population setting(s) can one expect vitamin A to be effective and what is the range of effect to be expected?. Where is improvement of vitamin A status most likely to affect morbidity and mortality?. The obvious answer to this question is: Where vitamin A deficiency is now a serious problem. For the mortality trials, all of which were conducted in settings where it was assumed vitamin A was a public health problem under the WHO definition, we attempted to ask about population-level predictors of the relative effect. Statistical power was very low for these analyses of the predictors of response (mortality of control group, xerophthalmia, stunting, wasting) since study was the unit of analysis (n = 8). Individual-level data might have uncovered more subtle ...

Vitamin A-deficient (A-) mice make strikingly poor IgG responses when they are immunized with purified protein antigens. Previously, we showed that A- T cells overproduce interferon gamma (IFN-gamma), which then could inhibit interleukin 4 (IL-4)-stimulated B cell IgG responses. To determine if the altered IFN-gamma regulation pattern and its immunological consequences would extend to a natural infection, we studied mice infected with the parasitic helminth Trichinella spiralis. The course of the infection was similar in A- and A-sufficient (A+) mice. These mice did not differ with respect to newborn larvae/female/hour produced in the intestine, or muscle larvae burden 5 wk postinfection. They also did not differ in the intestinal worm expulsion rate until day 15, when A- mice still harbored parasites, whereas A+ mice had cleared intestinal worms. Vitamin A deficiency reduced both the frequency of B lymphocytes secreting IgG1 antibodies to parasite antigens, and the bone marrow eosinophilia ...
Degradation of beta-carotene during storage is a problem that may prove even more troublesome for the proposed nutritional benefits of Golden Rice than its initial low levels.. Unnoticed by the media, a 2017 paper published in the Journal of Agricultural and Food Chemistry reported that the beta-carotene content of Golden Rice GR2E at harvest is short-lived (Schaub et al. 2017).. This study found Golden Rice retained only 60% of its original beta-carotene levels after 3 weeks of storage and just 13% after 10 weeks.. The apparent explanation is that the beta-carotene in Golden Rice is unstable in the presence of oxygen. Thus, under normal storage conditions, the beta-carotene in Golden Rice grains will rapidly degrade.. Under tropical farming, storage, and household conditions, degradation may be faster still.. In any event, the low levels and rapid degradation of beta-carotene measured in Golden Rice GR2E seem a significant blow to the likelihood that Golden Rice will fulfill expectations. That ...
If these strategies do not work, poor vitamin A status should be considered a possible explanation. This interpretation is strengthened if you have poor night vision (for example, if you strain your eyes or have trouble seeing when driving down an unlit road with your headlights alone but can see fine without any eyestrain during the day) or dry eyes. This interpretation is also strengthened if you have serum retinol near or below the bottom of the reference range, or if you track your vitamin A intake and your daily average is below the RDA.. It is important to note that any of these additional pieces of evidence strengthen the interpretation of poor vitamin A status, but their absence does not rule it out. If circadian rhythm disruption is more sensitive to deficiency than night blindness, then it may occur in the absence of other clinical signs, at serum retinol concentrations within the reference range, and at vitamin A intakes above the RDA.. The best way to ensure basic adequacy of vitamin ...

Y1 - 1995. N2 - Acute infections of childhood are associated with an increased rate of xerophthalmia, apparently due to depletion of vitamin A stores. The mechanism responsible for this is not known. Recently, it has been reported that severe infections in adult patients (ie, sepsis and pneumonia) result in excretion of large quantities of retinol in the urine. In 44 children hospitalized for treatment of acute diarrhea we found mean urinary excretions of 1.44 μmol retinol/24 h on day 1 of hospitalization, 0.62 μmol retinol/24 h on day 2, and 0.23 μmol/24 h on day 3. Healthy control subjects matched for age did not excrete measurable amounts of retinol in the urine. Retinol excretion was associated strongly with rotavirus diarrhea and presence of fever. Furthermore, serum retinol concentration was ...

Amy Skversky, M.D., M.S.When doctors write that prescription for steroids and theyre sending the patients for lab tests, they should also get the vitamin D level measured, said study lead author Amy Skversky, M.D., M.S., assistant professor of pediatrics at Einstein and Montefiore Medical Center, the University Hospital for Einstein.. The severe vitamin D deficiency assessed in this study (defined as levels below 10 nanograms per milliliter of blood) is known to be associated with osteomalacia (softening of the bones), rickets (softening of bones in children) and clinical myopathy (muscle weakness). While there is much debate on the issue, vitamin D levels between 20 and 50 ng/ml are generally considered adequate for bone and overall health in healthy individuals. Steroids have been shown to cause vitamin D deficiency, possibly by increasing levels of an enzyme that inactivates the vitamin.. Smaller studies involving people often prescribed steroids (i.e., children with asthma and patients ...
Purpose:To identify children aged 0-72 months with blinding xerophthalmia in the North West Frontier Province (NWFP) and its adjoining Federally Administered Tribal Areas (FATA) in Pakistan, using a new surveillance system, and to describe socio-economic and other characteristics of reported cases. Methods: All ophthalmologists in district headquarter hospitals in NWFP and agency headquarter hospitals in FATA were requested to participate in a surveillance programme for the detection of blinding xerophthalmia (corneal xerosis, corneal ulcers, keratomalacia and corneal scars related to vitamin A deficiency) for children aged 0-72 months. The surveillance included reporting of each case of blinding xerophthalmia presenting to the participating eye units over a period of 12 months and recording their socio-economic and other related characteristics. Results: Seventy six cases of blinding xerophthalmia were reported and there was almost no gender difference. Children came from 19 of 31 districts and

a. Number of cases.. Vitamin-A deficiency (xerophthalmia and keratomalacia). Untreated vitamin-A deficiency leads to irreversible blindness and death. Growing children are at the greatest risk of developing signs of xerophthalmia because of their higher vitamin-A requirement and also because they have a higher rate of infections. A close association between even moderate vitamin-A deficiency and increased morbidity and mortality from respiratory and gastro-intestinal infections has been reported [8].. The lead time for the signs to develop depends on the level of vitamin A stored in the body. Refugees most often arrive in camps with low vitamin-A stores after subsisting on a deficient diet prior to and during their exodus, and during initial periods in the country of asylum. Thus, the lead time for developing xerophthalmia in refugees can be expected to be shorter than in a population that suffers vitamin-A deficiency without previous malnutrition.. Iron deficiency (anaemia). Anaemia can have ...

Several studies have shown that klf2 activates the expression of vascular genes including endothelial NO synthase (eNOS).16,30,34 NO is involved in several physiologic and pathologic events. In particular, NO produced by the eNOS is a fundamental determinant of cardiovascular homeostasis, including systemic blood pressure, vascular remodeling, and angiogenesis.35 In cultured endothelial cells, shear stress and other factors have been shown to increase eNOS expression.36 To determine whether NO signaling was altered in tnnt2a- and klf2a-deficient embryos, we first used NO imaging to visualize NO production in live embryos. DAF-FM staining showed that NO production was reduced in the tnnt2a- and klf2a-deficient embryos (Figure 7B-C red arrows), compared with that in controls. To further test whether NO signaling was involved in the blood flow response required for HSC development, we examined nos1 and nos2a/2b expression in klf2a-deficient embryos. nos1 and nos2b expression was significantly ...

When my 83-year-old mom-in-law was dying of bowel cancer, her doctor could not use the D word with her, either.. Somehow, she was under the impression that all these last ditch efforts they were making-the massive doses of antibiotics to hold back her pneumonia, the surgery to insert a shunt to because her kidneys were failing-well, she thought all these things were done because there was hope. Thing was, hope had left the building a month ago. The cancer had spread to her kidneys. It was a race between the kidney cancer and the pneumonia. Her kidneys quit first. Her doctor was straight with us, but not with her.. When her doctor finally screwed up the courage to tell her that she was in palliative care, that nothing more could be done, she made her peace with dying, said her good-byes, lapsed into a coma and died peacefully within 36 hours.. I have seen three parents through palliative care for cancer now-my father, my dad-in-law and my mom-in-law. The doctors were quite forthcoming with both ...

In the 1940s and 50s, psychiatrists often used insulin-shock therapy to treat mental illness.

After about an hour, the doctor would administer glucose to bring the patient out of the coma.
