Reduced cytosolic acidification during exercise suggests defective glycolytic activity in skeletal muscle of patients with Becker muscular dystrophy. An in vivo 31P magnetic resonance spectroscopy study. (1/1658)

Becker muscular dystrophy is an X-linked disorder due to mutations in the dystrophin gene, resulting in reduced size and/or content of dystrophin. The functional role of this subsarcolemma protein and the biochemical mechanisms leading to muscle necrosis in Becker muscular dystrophy are still unknown. In particular, the role of a bioenergetic deficit is still controversial. In this study, we used 31p magnetic resonance spectroscopy (31p-MRS) to investigate skeletal muscle mitochondrial and glycolytic ATP production in vivo in 14 Becker muscular dystrophy patients. Skeletal muscle glycogenolytic ATP production, measured during the first minute of exercise, was similar in patients and controls. On the other hand, during later phases of exercise, skeletal muscle in Becker muscular dystrophy patients was less acidic than in controls, the cytosolic pH at the end of exercise being significantly higher in Becker muscular dystrophy patients. The rate of proton efflux from muscle fibres of Becker muscular dystrophy patients was similar to that of controls, pointing to a deficit in glycolytic lactate production as a cause of higher end-exercise cytosolic pH in patients. The maximum rate of mitochondrial ATP production was similar in muscle of Becker muscular dystrophy patients and controls. The results of this in vivo 31P-MRS study are consistent with reduced glucose availability in dystrophin-deficient muscles.  (+info)

Incubation of OKP cells in low-K+ media increases NHE3 activity after early decrease in intracellular pH. (2/1658)

Chronic hypokalemia increases the activity of proximal tubule apical membrane Na+/H+ antiporter NHE3. The present study examined the effect of the incubation of OKP cells (an opossum kidney, clone P cell line) in control medium (K+ concn ([K+]) = 5.4 mM) or low-K+ medium ([K+] = 2.7 mM) on NHE3. The activity of an ethylisopropyl amiloride-resistant Na+/H+ antiporter, whose characteristics were consistent with those of NHE3, was increased in low-K+ cells beginning at 8 h. NHE3 mRNA and NHE3 protein abundance were increased 2.2-fold and 62%, respectively, at 24 h but not at 8 h. After incubation in low-K+ medium, intracellular pH (pHi) decreased by 0.27 pH units (maximum at 27 min) and then recovered to the control level. Intracellular acidosis induced by 5 mM sodium propionate increased Na+/H+ antiporter activity at 8 and 24 h. Herbimycin A, a tyrosine kinase inhibitor, blocked low-K+- and sodium propionate-induced activation of the Na+/H+ antiporter at 8 and 24 h. Our results demonstrate that low-K+ medium causes an early decrease in pHi, which leads to an increase in NHE3 activity via a tyrosine kinase pathway.  (+info)

Effect of acidification on the location of H+-ATPase in cultured inner medullary collecting duct cells. (3/1658)

In previous studies, our laboratory has utilized a cell line derived from the rat inner medullary collecting duct (IMCD) as a model system for mammalian renal epithelial cell acid secretion. We have provided evidence, from a physiological perspective, that acute cellular acidification stimulates apical exocytosis and elicits a rapid increase in proton secretion that is mediated by an H+-ATPase. The purpose of these experiments was to examine the effect of acute cellular acidification on the distribution of the vacuolar H+-ATPase in IMCD cells in vitro. We utilized the 31-kDa subunit of the H+-ATPase as a marker of the complete enzyme. The distribution of this subunit of the H+-ATPase was evaluated by immunohistochemical techniques (confocal and electron microscopy), and we found that there is a redistribution of these pumps from vesicles to the apical membrane. Immunoblot evaluation of isolated apical membrane revealed a 237 +/- 34% (P < 0.05, n = 9) increase in the 31-kDa subunit present in the membrane fraction 20 min after the induction of cellular acidification. Thus our results demonstrate the presence of this pump subunit in the IMCD cell line in vitro and that cell acidification regulates the shuttling of cytosolic vesicles containing the 31-kDa subunit into the apical membrane.  (+info)

HaCaT human keratinocytes express IGF-II, IGFBP-6, and an acid-activated protease with activity against IGFBP-6. (4/1658)

The insulin-like growth factor (IGF) system plays an important role in skin. HaCaT human keratinocytes proliferate in response to IGFs and synthesize IGF-binding protein-3 (IGFBP-3). Recently, IGFBP-6 was also identified by NH2-terminal sequencing, but it has not been identified by Western ligand blotting. In the present study, IGFBP-6 was detected in HaCaT-conditioned medium by use of immunoblotting and Western ligand blotting with 125I-labeled IGF-II. Proteolytic activity against IGFBPs, an important mechanism for regulation of their activity, was then studied. An acid-activated, cathepsin D-like protease that cleaved both IGFBP-6 and IGFBP-3 was detected. Although proteolysis did not substantially reduce the size of immunoreactive IGFBP-6, it greatly reduced the ability of IGFBP-6 to bind 125I-IGF-II as determined by Western ligand blotting and solution assay. HaCaT keratinocytes do not express IGF-I mRNA, but IGF-II mRNA and protein expression was detected. These observations suggest the possibility of an autocrine IGF-II loop that is regulated by the relative expression of IGF-II, IGFBP-3, and IGFBP-6, and IGFBP proteases in these keratinocytes, although demonstration of this loop requires further study.  (+info)

Identification of nonlipophilic corynebacteria isolated from dairy cows with mastitis. (5/1658)

Nonlipophilic corynebacteria associated with clinical and subclinical mastitis in dairy cows were found to belong to four species: Corynebacterium amycolatum, Corynebacterium ulcerans, Corynebacterium pseudotuberculosis, and Corynebacterium minutissimum. These species may easily be confused. However, clear-cut differences between C. ulcerans and C. pseudotuberculosis were found in their acid production from maltotriose and ethylene glycol, susceptibility to vibriostatic agent O129, and alkaline phosphatase. Absence of growth at 20 degrees C and lack of alpha-glucosidase and 4MU-alpha-D-glycoside hydrolysis activity differentiated C. amycolatum from C. pseudotuberculosis and C. ulcerans. The mastitis C. pseudotuberculosis strains differed from the biovar equi and ovis reference strains and from caprine field strains in their colony morphologies and in their reduced inhibitory activity on staphylococcal beta-hemolysin. C. amycolatum was the most frequently isolated nonlipophilic corynebacterium.  (+info)

The acid-inducible asr gene in Escherichia coli: transcriptional control by the phoBR operon. (6/1658)

Escherichia coli responds to external acidification (pH 4.0 to 5.0) by synthesizing a newly identified, approximately 450-nucleotide RNA component. At maximal levels of induction it is one of the most abundant small RNAs in the cell and is relatively stable bacterial RNA. The acid-inducible RNA was purified, and the gene encoding it, designated asr (for acid shock RNA), mapped at 35.98 min on the E. coli chromosome. Analysis of the asr DNA sequence revealed an open reading frame coding for a 111-amino-acid polypeptide with a deduced molecular mass of approximately 11.6 kDa. According to computer-assisted analysis, the predicted polypeptide contains a typical signal sequence of 30 amino acids and might represent either a periplasmic or an outer membrane protein. The asr gene cloned downstream from a T7 promoter was translated in vivo after transcription using a T7 RNA polymerase transcription system. Expression of a plasmid-encoded asr::lacZ fusion under a native asr promoter was reduced approximately 15-fold in a complex medium, such as Luria-Bertani medium, versus the minimal medium. Transcription of the chromosomal asr was abolished in the presence of a phoB-phoR (a two-component regulatory system, controlling the pho regulon inducible by phosphate starvation) deletion mutant. Acid-mediated induction of the asr gene in the Delta(phoB-phoR) mutant strain was restored by introduction of the plasmid with cloned phoB-phoR genes. Primer extension analysis of the asr transcript revealed a region similar to the Pho box (the consensus sequence found in promoters transcriptionally activated by the PhoB protein) upstream from the determined transcription start. The asr promoter DNA region was demonstrated to bind PhoB protein in vitro. We discuss our results in terms of how bacteria might employ the phoB-phoR regulatory system to sense an external acidity and regulate transcription of the asr gene.  (+info)

Screening procedure for detection of dihydropyridine calcium channel blocker metabolites in urine as part of a systematic toxicological analysis procedure for acidic compounds by gas chromatography-mass spectrometry after extractive methylation. (7/1658)

A gas chromatographic-mass spectrometric (GC-MS) screening procedure was developed for the detection of dihydropyridine calcium channel blocker ("calcium antagonist") metabolites in urine as part of a systematic toxicological analysis procedure for acidic drugs and poisons after extractive methylation. The part of the phase-transfer catalyst remaining in the organic phase was removed by solid-phase extraction on a diol phase. The compounds were separated by capillary GC and identified by computerized MS in the full scan mode. Using mass chromatography with the ions m/z 139, 284, 297, 298, 310, 312, 313, 318, 324, and 332, the possible presence of calcium channel blocker metabolites could be indicated. The identity of positive signals in such mass chromatograms was confirmed by comparison of the peaks underlying full mass spectra with the reference spectra recorded during this study. This method allowed the detection of therapeutic concentrations of amlodipine, felodipine, isradipine, nifedipine, nilvadipine, nimodipine, nisoldipine, and nitrendipine in human urine samples. Because urine samples from patients treated with nicardipine were not available, the detection of nicardipine in rat urine was studied. The overall recovery ranged between 67 and 77% with a coefficient of variation of less than 10%, and the limit of detection was at least 10 ng/mL (signal-to-noise ratio = 3) in the full-scan mode.  (+info)

Novel form of spreading acidification and depression in the cerebellar cortex demonstrated by neutral red optical imaging. (8/1658)

A novel form of spreading acidification and depression in the rat cerebellar cortex was imaged in vivo using the pH-sensitive dye, Neutral red. Surface stimulation evoked an initial beam of increased fluorescence (i.e., decreased pH) that spread rostrally and caudally across the folium and into neighboring folia. A transient but marked suppression in the excitability of the parallel fiber-Purkinje cell circuitry accompanied the spread. Characteristics differentiating this phenomenon from the spreading depression of Leao include: high speed of propagation on the surface (average of 450 microm/s), stable extracellular DC potential, no change in blood vessel diameter, and repeatability at short intervals. This propagating acidification constitutes a previously unknown class of neuronal processing in the cerebellar cortex.  (+info)

Healthy Bones and Children Long-Term Protein Intake and Dietary Potential Renal Acid Load are Associated with Bone Modeling and Remodeling at the Proximal Radius in Healthy Children
Aims/hypothesis: Studies suggest a potential link between low-grade metabolic acidosis and type 2 diabetes. A western dietary pattern increases daily acid load but the association between diet-dependent acid load and type 2 diabetes is still unclear. This study aimed to assess whether diet-dependent acid load is associated with the risk of type 2 diabetes. Methods: We examined the association between energy-adjusted net endogenous acid production (NEAP), potential renal acid load (PRAL) and animal protein-to-potassium ratio (A:P) on incident type 2 diabetes in 67,433 women from the Nurses Health Study, 84,310 women from the Nurses Health Study II and 35,743 men from the Health Professionals Follow-up Study who were free from type 2 diabetes, cardiovascular disease and cancer at baseline. Study-specific HRs were estimated using Cox proportional hazards models with time-varying covariates and were pooled using a random effects meta-analysis. Results: We documented 15,305 cases of type 2 ...
Dietary protein is theorized to hold both anabolic effects on bone and demineralizing effects mediated by the diet acid load of sulfate derived from methionine and cysteine. The relative importance of these effects is unknown but relevant to osteoporosis prevention. Postmenopausal women (n = 161, 67.9 +/- 6.0 y) were assessed for areal bone mineral density (aBMD) of lumbar spine (LS) and total hip (TH) using dual X-ray absorptiometry, and dietary intakes of protein, sulfur-containing amino acids, and minerals using a USDA multiple-pass 24-h recall. The acidifying influence of the diet was estimated using the ratio of protein:potassium intake, the potential renal acid load (PRAL), and intake of sulfate equivalents from protein. aBMD was regressed onto protein intake then protein was controlled for estimated dietary acid load. A step-down procedure assessed potential confounding influences (weight, age, physical activity, and calcium and vitamin D intakes). Protein alone did not predict LS aBMD (P ...
Streptococcus pneumoniae, one of the major causes of morbidity and mortality in humans, faces a range of potentially acidic conditions in the middle and late stages of growth in vitro, in diverse human fluids during the infection process, and in biofilms present in the nasopharynx of carriers. S. pneumoniae was shown to develop a weak acid tolerance response (ATR), where cells previously exposed to sublethal pHs (5·8-6·6) showed an increased survival rate of up to one order of magnitude after challenge at the lethal pH (4·4, survival rate of 10−4). Moreover, the survival after challenge of stationary phase cells at pH 4·4 was three orders of magnitude higher than that of cells taken from the exponential phase, due to the production of lactic acid during growth and increasing acidification of the growth medium until stationary phase. Global expression analysis after short-term (5, 15 and 30 min, the adaptation phase) and long-term (the maintenance phase) acidic shock (pH 6·0) was performed by

Changes in cytoplasmic pH of suspension-cultured cells of Catharanthus roseus under extreme acid conditions were measured with the pH-dependent fluorescence dye; 2′,7′-bis-(2-carboxyethyl)-5 (and-6) carboxyfluorescein (-acetoxymethylester) (BCECF). When cells were treated with 1 mM HC1 (pH 3 solution), the cytoplasmic pH first decreased then returned to the original level. Treatment with 10 mM HC1 (pH 2 solution) acidified the cytoplasm to a greater extent, and the acidification continued at a constant level throughout the measurement. Treatment with a pH 2 solution resulted in a gradual decrease of the malate content, indicating the operation of biochemical pH regulation mechanism. The pH 2 treatment also caused a sudden decrease of the intracellular level of Pi. The cellular content of total phosphorus did not change during the acidification. The Pi was converted to the organic phosphate form. The ATP level was not increased by the pH 2 treatment, but slightly decreased. The role of Pi, ...

Virulent Salmonella typhimurium strains differ from the attenuated laboratory strain LT2 at the rpoS locus. It was previously shown that the rpoS gene in strain LT2 contains a rare UUG start codon (I. S. Lee, J. Lin, H. K. Hall, B. Bearson, and J. W. Foster, Mol. Microbiol. 17:155-167, 1995). This difference is responsible for the inability of LT2 to display a sustained log-phase acid tolerance response. We show that the altered rpoS allele (rpoS(LT2)) also affects the stationary-phase acid tolerance response in Salmonella. By transducing the rpoS(LT2) allele into virulent strain backgrounds and crossing wild-type rpoS allele into strain LT2, we demonstrate that the rpoS(LT2) allele contributes to the attenuation of strain LT2. We examined the effect of the rpoS allele on invasion and found that the rpoS status of the cell had no effect on the ability of the strains to invade intestinal epithelial cells in tissue culture. Enumeration of bacteria from tissues of infected mice indicated that the ...

The bodys pH can get imbalanced due to stress, lack of sleep, and over consumption of acidic foods (such as sugar, processed foods and alcohol). When our bodys pH is off balance, serious problems result. To balance the bodys pH, the body will start to draw alkalizing minerals away from bones, organs, and tissues. This depletion of resources, combined with the fact that viruses, bacteria, cancer and parasites thrive in acidic environments, opens the door to imbalance and disease in the body. Adding Balance ...

TY - JOUR. T1 - Can ocean acidification affect population dynamics of the barnacle Semibalanus balanoides at its southern range edge?. AU - Findlay, Helen S.. AU - Burrows, Michael. AU - Kendall, Michael A. AU - Spicer, J. I.. AU - Widdicombe, Stephen. PY - 2010. Y1 - 2010. N2 - The global ocean and atmosphere are warming. There is increasing evidence suggesting that, in addition to other environmental factors, climate change is affecting species distributions and local population dynamics. Additionally, as a consequence of the growing levels of atmospheric carbon dioxide (CO2), the oceans are taking up increasing amounts of this CO2, causing ocean pH to decrease (ocean acidification). The relative impacts of ocean acidification on population dynamics have yet to be investigated, despite many studies indicating that there will be at least a sublethal impact on many marine organisms, particularly key calcifying organisms. Using empirical data, we forced a barnacle (Semibalanus balanoides) ...

TY - JOUR. T1 - Effect of ocean acidification on the speciation of metals in seawater. AU - Millero, Frank J.. AU - Woosley, Ryan. AU - Ditrolio, Benjamin. AU - Waters, Jason. PY - 2009/12. Y1 - 2009/12. N2 - Increasing atmospheric CO 2 over the next 200 years will cause the pH of ocean waters to decrease further. Many recent studies have examined the effect of decreasing pH on calcifying organisms in ocean waters and on other biological processes (photosynthesis, nitrogen fixation, elemental ratios, and community structure). In this review, we examine how pH will change the organic and inorganic speciation of metals in surface ocean waters, and the effect that it will have on the interactions of metals with marine organisms. We consider both kinetic and equilibrium processes. The decrease in concentration of OH - and CO 3 2- ions can affect the solubility, adsorption, toxicity, and rates of redox processes of metals in seawater. Future studies are needed to examine how pH affects the ...

A major issue in microbial ecology is to identify the limits of life for growth and survival, and to understand the molecular mechanisms that define these limits. Thus, interest in the biodiversity and ecology of extreme environments has grown in recent years for several reasons. Some are basic and revolve around the idea that extreme environments are believed to reflect early Earth conditions. Others are related to the biotechnological potential of extremophiles. In this regard, the study of extremely acidic environments has become increasingly important since environmental acidity is often caused by microbial activity. Highly acidic environments are relatively scarce worldwide and are generally associated with volcanic activity or mining operations. For most acidic environments, low pH facilitates metal solubility, and therefore acidic waters tend to have high concentrations of heavy metals. However, highly acidic environments are usually inhabited by acidophilic and acidotolerant eukaryotic

We cloned, overexpressed, purified, and characterized HdeB as a novel acid stress chaperone. HdeB was found in the periplasm in a soluble form. It was purified by osmotic shock, followed by two chromatographic steps on DEAE-Sephacel and hydroxyapatite columns, and identified by matrix-assisted laser desorption ionization-time of flight mass spectrometry. We purified HdeA in parallel in order to compare the two chaperones.. A periplasmic extract from the hdeB mutant aggregated at pH 2 and pH 3, like an extract from the hdeA mutant (9). The aggregation defect of the hdeB mutant did not result from the lower expression (24% of the wild-type level) of HdeA, since complementation of this mutant by the HdeA expression plasmid did not rescue its aggregation defect. Thus, HdeB is important for the solubility of the bacterial periplasm at acidic pH.. At pH 2, HdeA is the main chaperone involved in the in vitro solubilization of periplasmic extracts and of the model substrate proteins used in our study ...

The transcriptional activator GadE, for Glutamic acid decarboxylase, is positively autoregulated [3, 14]and controls the transcription of genes involved in the maintenance of pH homeostasis, including the principal acid resistance system [3, 4, 5, 6, 8, 17, 18, 19] glutamate dependent (GAD), also referred as the GAD system, and genes involved in multidrug efflux, among others [3, 12, 13, 20, 21, 22] GadE also controls the expression of two transcription factors related to acid resistance, GadW and GadX, and for this reason it is considered the central activator of the acid response system [3, 4] GadE is encoded by the gadE-mdtEF operon, inducible by low pH [8] which is located in the region called the acid fitness island [21] Expression of gadE is controlled by an unusually large 798-bp upstream intergenic region, termed the sensory integration locus [15] At least six regulators related to the acid resistance system, GadE, GadX, GadW, EvgA, YdeO, and MnmE, are involved in the direct regulation ...
A titration in which a weak base is titrated with a strong acid will look very similar to the previous titration curve, except backwards. As we add more NaOH(aq) past the equivalence point for the neutralisation reaction, the moles of OH-(aq) in this added volume of solution are all in excess, so the pH of the solution increases, but as we keep adding more and more NaOH(aq) the line levels off as it approaches the pH of the NaOH(aq) being added (for 0.200 mol L-1 NaOH(aq) pH = 13.3). This particular resource used the following sources: The curves turning point is the equivalence point, right where the amount of hydroxide added matches the amount of acetic acid originally present. Titration curves for weak acid v strong base:- 20. The simplest acid-base reactions are those of a strong acid with a strong base. When the NaOH is in excess, the pH change is the same as in any system dominated by NaOH. A titration in which a weak acid is titrated with a strong base will look ...

Many E. coli genes show pH-dependent expression during logarithmic growth in acid (pH 5-6) or in base (pH 8-9). The effect of rapid pH change, however, has rarely been tested. Rapid acid treatment could distinguish between genes responding to external pH, and genes responding to cytoplasmic acidification, which occurs transiently following rapid external acidification. It could reveal previously unknown acid-stress genes whose effects are transient, as well as show which acid-stress genes have a delayed response. Microarray hybridization was employed to observe the global gene expression of E. coli K-12 W3110 following rapid acidification of the external medium, from pH 7.6 to pH 5.5. Fluorimetric observation of pH-dependent tetR-YFP showed that rapid external acidification led to a half-unit drop in cytoplasmic pH (from pH 7.6 to pH 6.4) which began to recover within 20 s. Following acid treatment, 630 genes were up-regulated and 586 genes were down-regulated. Up-regulated genes included amino-acid

Introduction. It is all about optimizing the performance of the oxide alternative chemistry. This includes close monitoring of the main reactive ingredients of the process chemistry. And one of the first issues that the industry had to address, whether one is using reduced oxide chemistry or oxide alternatives, is pink ring. While the industry has enjoyed moderate success at minimizing the dreaded pink ring defect with reduced oxides, the desire has long been to simplify the bonding treatment process. Secondly, improving bond strength on high-performance and advanced resin materials is critical to the successful implementation of any interlayer treatment process. While the latter attribute is well documented, the ability of the oxide alternative bonding system to resist pink ring must be established. In all instances, where multilayer PWB test coupons (some fabricated with reduced oxide, others with alternative bonding treatment) were subjected a severe acid test, no pink ring was detected. The ...

Cordain has lots of opinions, and this page is 100% opinion. Its very hard to take him seriously when one has seen the effects of eating 6 egg yolks a day (each +23.4units)! Most people who have perused the European literature will regard uroliths as a product of insulin resistance. There are some refs below. It applies to struvite sones too, lost the ref. Acid base looks to be much less important, noting that acidifying the urine using ascorbate DECREASES stone formation (ref 2). Again, anyone who has eaten LC, and particularly high fat, will be well aware of the effect on blood pressure (it normalises). Ive not particularly chased his other subjects amenable to decreasing acid load, but I would guess theyre all amenable to LC and dumping the PUFA. The PRAL ref cited is where he gets his data, theres nothing there to suggest decreasing acid load does any of the things he cites. Eating a decent paleo diet will do it, but whether its the decreased acid load or the lack of Pepsicola is all ...

pH balance or pH homeostasis in humans commonly refers to the internal balance of the bodys electro-magnetic and chemical systems in response to the changing conditions of the external world and the changing conditions of the internal world. The word homeostasis comes from the Greek words: homeo means similar or alki or alkaline and stasis means a tendency toward maintaining stability. There are many homoeostatic mechanisms in our bodies that help maintain this balance and our state of health is directly related to the health of these mechanisms. pH homeostasis is maintained by dynamic processes of feedback and regulation. pH homeostasis has only one objective: to preserve the beneficial conditions of life in the internal alkali environment. Every day we are bombarded with external influences that threaten that balanced internal alkaline pH environment. Some of these threats include becoming too hot or too cold, eating too much or eating acidic foods or drinks, breathing polluted air ...
By means of vital staining with indicators a study has been made of the changes in reaction and in certain other attributes of a tissue abruptly rendered ischemic. Grafts of mouse skin have been employed as test material. It has been found that almost at once after implantation vigorous grafts become notably acid as compared with the normal skin and that they survive and take despite the acid condition, which remains at a maximum for several days. Weak or injured grafts on the contrary tend to be as alkaline as their surroundings, if not more so. Through experiments directed to the purpose reasons for this difference have been found in the lessened metabolic activities of the cells of the injured skin, and in an increased permeability which leads to a generalized suffusion of the damaged tissue with the alkaline lymph and an abnormally rapid escape of carbon dioxide from it. The influence of these factors to determine the reaction of tissues dying within the body has not been sufficiently ...

  • Linoleic acid," claims first author Jyrki Virtanen, an adjunct professor of nutritional epidemiology, "is the most common polyunsaturated omega-6 fatty acid. (
  • The reason behind this thinking lies in the fact that our bodies convert dietary linoleic acid into another omega-6 fatty acid called arachidonic acid, which, in turn, is used to make certain pro-inflammatory compounds. (
  • Unlike linoleic acid, blood levels of arachidonic acid are not diet-dependent. (
  • However, the notion that a diet high in omega-6 fatty acids such as linoleic acid raises disease risk by promoting inflammation ignores the fact that omega-6 fatty acids also promote anti-inflammatory compounds. (
  • For their analysis, the researchers put the men in five groups ranked according to their blood level of linoleic acid, and they then compared the rates of death in the five groups. (
  • They found that the group with the highest blood levels of linoleic acid had a 43 percent lower risk of death than the group with the lowest levels. (
  • These findings are consistent with those of other studies that followed large groups and found links between high dietary and blood levels of linoleic acid and reduced risk of diseases such as type 2 diabetes and cardiovascular disease, while not raising the risk of cancer. (
