    Benfotiamine, a synthetic S-acyl thiamine derivative, has different mechanisms of action and a different pharmacological profile than lipid-soluble thiamine disulfide derivatives. Volvert ML, Seyen S, Piette M, Evrard B, Gangolf M, Plumier JC, Bettendorff L. BMC Pharmacol. 2008 Jun 12;8:10. PMID: 18549472 doi:10.1186/1471-2210-8-10 Conclusion Our results show that, though benfotiamine strongly increases thiamine levels in blood and liver, it has no significant effect in the brain. This would explain why beneficial effects of benfotiamine have only been observed in peripheral tissues, while sulbutiamine, a lipid-soluble thiamine disulfide derivative, that increases thiamine derivatives in the brain as well as in cultured cells, acts as a central nervous system drug. We propose that benfotiamine only penetrates the cells after dephosphorylation by intestinal alkaline phosphatases. It then enters the bloodstream as S-benzoylthiamine that is converted to thiamine in erythrocytes and in the liver. Benfotiamine, an S-acyl derivative practically insoluble in organic solvents, should therefore be differentiated from truly lipid-soluble thiamine disulfide derivatives (allithiamine and the synthetic sulbutiamine and fursultiamine) with a different mechanism of absorption and different pharmacological properties.

Spices halt growth of breast stem cells, U-M study finds - 0 views

  •  
    "ANN ARBOR, Mich. - A new study finds that compounds derived from the spices turmeric and pepper could help prevent breast cancer by limiting the growth of stem cells, the small number of cells that fuel a tumor's growth. Researchers at the University of Michigan Comprehensive Cancer Center have found that when the dietary compounds curcumin, which is derived from the Indian spice turmeric, and piperine, derived from black peppers, were applied to breast cells in culture, they decreased the number of stem cells while having no effect on normal differentiated cells. "If we can limit the number of stem cells, we can limit the number of cells with potential to form tumors," says lead author Madhuri Kakarala, M.D., Ph.D., R.D., clinical lecturer in internal medicine at the U-M Medical School and a research investigator at the VA Ann Arbor Healthcare System."

    n-3 fatty acids and cardiovascular disease. Breslow JL. Am J Clin Nutr. 2006 Jun;83(6 Suppl):1477S-1482S. Review. PMID: 16841857 The results of prospective cohort studies indicate that consuming fish or fish oil containing the n-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) is associated with decreased cardiovascular death, whereas consumption of the vegetable oil-derived n-3 fatty acid {alpha}-linolenic acid is not as effective. Randomized control trials (RCTs) in the context of secondary prevention also indicate that the consumption of EPA plus DHA is protective at doses 3 g/d, EPA plus DHA can improve cardiovascular disease risk factors, including decreasing plasma triacylglycerols, blood pressure, platelet aggregation, and inflammation, while improving vascular reactivity. Mainly on the basis of the results of RCTs, the American Heart Association recommends that everyone eat oily fish twice per week and that those with coronary heart disease eat 1 g/d of EPA plus DHA from oily fish or supplements. Directions for future research include 1) RCTs to confirm the initial trials showing that EPA plus DHA decreases cardiovascular death and additional studies to determine whether this effect is due to EPA, DHA, or the combination; the dosage of the effective components; and whether the mechanism of action in humans is prevention of fatal arrhythmias. 2) Clinical studies to determine whether the reduction in cardiovascular disease risk factors is due to EPA, DHA, or the combination and the dosage of the effective components. 3) Clinical studies to determine whether vegetable oil-derived {alpha}-linolenic acid added to a diet enriched in n-6 fatty acids can effectively substitute for fish oil-derived EPA plus DHA.

Omega-3 rather than genetics is key to lack of CHD in Japanese? - theheart.org - 0 views

  •  
    Pittsburgh, PA and Shiga, Japan - The low rate of atherosclerosis and heart disease in Japanese people may be related to their very high levels of marine-derived omega-3 fatty acids rather than genetic factors, a new study suggests [1]. The study, published in the August 5, 2008 issue of the Journal of the American College of Cardiology (available online July 28), was conducted by a group led by Dr Akira Sekikawa (University of Pittsburgh, PA, and Shiga University of Medical Science, Japan). They found that compared with white or Japanese American men living in the US, Japanese men living in Japan had twice the blood levels of omega-3 fatty acids-a finding that was independently linked to low levels of atherosclerosis. "The death rate from coronary heart disease in Japan has always been puzzlingly low. Our study suggests that the very low rates of coronary heart disease among Japanese living in Japan may be due to their lifelong high consumption of fish," Sekikawa said." Results showed that the Japanese men had the lowest levels of atherosclerosis, whereas whites and Japanese Americans had similar higher levels. The Japanese men also had twofold higher levels of marine-derived omega-3 fatty acids than white and Japanese Americans. In addition, the significant differences between Japanese and American men in multivariable-adjusted IMT and CAC prevalence became nonsignificant after adjustment further for marine-derived omega-3 fatty acids.

    Fish oil-derived fatty acids, docosahexaenoic acid and docosapentaenoic acid, and the risk of acute coronary events: the Kuopio ischaemic heart disease risk factor study. Rissanen T, Voutilainen S, Nyyssönen K, Lakka TA, Salonen JT. Circulation. 2000 Nov 28;102(22):2677-9. PMID: 11094031 Methods and Results-We studied this association in the Kuopio Ischaemic Heart Disease Risk Factor Study, a prospective population study in Eastern Finland. Subjects were randomly selected and included 1871 men aged 42 to 60 years who had no clinical coronary heart disease at baseline examination. A total of 194 men had a fatal or nonfatal acute coronary event during follow-up. In a Cox proportional hazards' model adjusting for other risk factors, men in the highest fifth of the proportion of serum DHA+DPA in all fatty acids had a 44% reduced risk (P=0.014) of acute coronary events compared with men in the lowest fifth. Men in the highest fifth of DHA+DPA who had a low hair content of mercury (2.0 µg/g). There was no association between proportion of eicosapentaenoic acid and the risk of acute coronary events. Conclusions-Our data provide further confirmation for the concept that fish oil-derived fatty acids reduce the risk of acute coronary events. However, a high mercury content in fish could attenuate this protective effect.

    Marine-derived n-3 fatty acids and atherosclerosis in Japanese, Japanese-American, and white men: a cross-sectional study. Sekikawa A, Curb JD, Ueshima H, El-Saed A, Kadowaki T, Abbott RD, Evans RW, Rodriguez BL, Okamura T, Sutton-Tyrrell K, Nakamura Y, Masaki K, Edmundowicz D, Kashiwagi A, Willcox BJ, Takamiya T, Mitsunami K, Seto TB, Murata K, White RL, Kuller LH; ERA JUMP (Electron-Beam Tomography, Risk Factor Assessment Among Japanese and U.S. Men in the Post-World War II Birth Cohort) Study Group. J Am Coll Cardiol. 2008 Aug 5;52(6):417-24. PMID: 18672160 Conclusions Very high levels of marine-derived n-3 FAs have anti-atherogenic properties independent of traditional cardiovascular risk factors and may contribute to lower burden of atherosclerosis in Japanese in Japan, which is unlikely due to genetic factors.

Omega-3 Rather Than Genetics Is Key to Lack of CHD in Japanese? - Medscape - 0 views

    July 29, 2008 - The low rate of atherosclerosis and heart disease in Japanese people may be related to their very high levels of marine-derived omega-3 fatty acids rather than genetic factors, a new study suggests [1]. The study, known as Electron-Beam Tomography, Risk Factor Assessment Among Japanese and US Men in the Post-World War II Birth Cohort (ERA JUMP) included 868 randomly selected men aged 40 to 49. Of these, 281 were Japanese men living in Japan; 306 were white men living in the US, and 281 were third- or fourth-generation Japanese American men from Hawaii. All study participants had a physical examination, completed a lifestyle questionnaire, and had blood tests to measure cholesterol levels and levels of omega-3 fatty acids. Atherosclerosis was assessed by measuring carotid intima-medial thickness (IMT) and coronary artery calcification (CAC). Results showed that the Japanese men had the lowest levels of atherosclerosis, whereas whites and Japanese Americans had similar higher levels. The Japanese men also had twofold higher levels of marine-derived omega-3 fatty acids than white and Japanese Americans. The study, published in the August 5, 2008 issue of the Journal of the American College of Cardiology (available online July 28), was conducted by a group led by Dr Akira Sekikawa (University of Pittsburgh, PA, and Shiga University of Medical Science, Japan). They found that compared with white or Japanese American men living in the US, Japanese men living in Japan had twice the blood levels of omega-3 fatty acids - a finding that was independently linked to low levels of atherosclerosis.

    Plant-animal subsistence ratios and macronutrient energy estimations in worldwide hunter-gatherer diets. Cordain L, Miller JB, Eaton SB, Mann N, Holt SH, Speth JD. Am J Clin Nutr. 2000 Mar;71(3):682-92. PMID: 10702160 Our analysis showed that whenever and wherever it was ecologically possible, hunter-gatherers consumed high amounts (45-65% of energy) of animal food. Most (73%) of the worldwide hunter-gatherer societies derived >50% (> or =56-65% of energy) of their subsistence from animal foods, whereas only 14% of these societies derived >50% (> or =56-65% of energy) of their subsistence from gathered plant foods. This high reliance on animal-based foods coupled with the relatively low carbohydrate content of wild plant foods produces universally characteristic macronutrient consumption ratios in which protein is elevated (19-35% of energy) at the expense of carbohydrates (22-40% of energy).

    The effect of omega-3 FAs on tumour angiogenesis and their therapeutic potential. Spencer L, Mann C, Metcalfe M, Webb M, Pollard C, Spencer D, Berry D, Steward W, Dennison A. Eur J Cancer. 2009 Aug;45(12):2077-86. Epub 2009 Jun 1. Review. PMID: 19493674 Omega-3 fatty acid (omega-3 FA) consumption has long been associated with a lower incidence of colon, breast and prostate cancers in many human populations. Human trials have demonstrated omega-3 FA to have profound anti-inflammatory effects in those with cancer. In vitro and small animal studies have yielded a strong body of evidence establishing omega-3 FA as having anti-inflammatory, anti-apoptotic, anti-proliferative and anti-angiogenic effects. This review explores the evidence and the mechanisms by which omega-3 FA may act as angiogenesis inhibitors and identifies opportunities for original research trialling omega-3 FAs as anti-cancer agents in humans. The conclusions drawn from this review suggest that omega-3 FAs in particular eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) found principally in oily fish have potent anti-angiogenic effects inhibiting production of many important angiogenic mediators namely; Vascular Endothelial Growth Factor (VEGF), Platelet-Derived Growth Factor (PDGF), Platelet-Derived Endothelial Cell Growth Factor (PDECGF), cyclo-oxygenase 2 (COX-2), prostaglandin-E2 (PGE2), nitric oxide, Nuclear Factor Kappa Beta (NFKB), matrix metalloproteinases and beta-catenin
