    Effect of vitamin D deficiency and replacement on endothelial function in asymptomatic subjects. Tarcin O, Yavuz DG, Ozben B, Telli A, Velioglu Ogunc A, Yuksel M, Toprak A, Yazici D, Sancak S, Deyneli O, Akalin S. J Clin Endocrinol Metab. 2009 Jul 7. [Epub ahead of print] PMID: 19584181 doi:10.1210/jc.2008-1212 Conclusions: This study shows that 25(OH)D deficiency is associated with endothelial dysfunction and increased lipid peroxidation. Replacement of vitamin D has favorable effects on endothelial function. Vitamin D deficiency can be seen as an independent risk factor of atherosclerosis. Hypovitaminosis D associated endothelial dysfunction may predispose to higher cardiovascular disease in the winter.

    These data indicate that fish oil feeding downregulated the endogenous PPAR-activation system and increased antioxidant gene expressions to protect against ROS excess Fish oil feeding alters liver gene expressions to defend against PPARalpha activation and ROS production.

Omega-3 Kills Cancer Cells - 0 views

  •  
    ScienceDaily (Apr. 5, 2009) - Docosahexanoic acid (DHA), an omega-3 fatty acid found in fish oils, has been shown to reduce the size of tumours and enhance the positive effects of the chemotherapy drug cisplatin, while limiting its harmful side effects. The rat experiments provide some support for the plethora of health benefits often ascribed to omega-3 acids.

DHA reduces tumor growth - Life Extension Update - 0 views

  •  
    Mice injected with cancer cells experienced significantly elevated levels of C-reactive protein, white blood cells, and lipid peroxidation compared with control mice. These levels were reduced in animals that received cisplatin and/or DHA. While treatment with 125 mg/kg DHA inhibited tumor growth by 38 percent compared to untreated animals, 250 mg/kg suppressed tumor growth by 79 percent, which was a greater effect than that of cisplatin alone (which was associated with a 55 percent reduction). The combination of DHA and cisplatin resulted in an 81 percent inhibition of growth, while reducing elevated white blood cell levels (leukocytosis) to normal levels. Treatment with the higher dose of DHA alone was associated with a similar reduction in white blood cells, which, when elevated, are associated with tumor growth. A strong relationship was observed between tumor growth and white blood cell levels as well as C-reactive protein levels. In another experiment with rats treated with cisplatin, the addition of 250 mg/kg DHA prevented lethal kidney toxicity in 88 percent of the animals that received it, while none of the rats that received cisplatin alone survived.

  •  
    Dark chocolate consumption increases HDL cholesterol concentration and chocolate fatty acids may inhibit lipid peroxidation in healthy humans. Mursu J, Voutilainen S, Nurmi T, Rissanen TH, Virtanen JK, Kaikkonen J, Nyyssönen K, Salonen JT. Free Radic Biol Med. 2004 Nov 1;37(9):1351-9. PMID: 15454274 doi:10.1016/j.freeradbiomed.2004.06.002 Cocoa polyphenols may increase the concentration of HDL cholesterol, whereas chocolate fatty acids may modify the fatty acid composition of LDL and make it more resistant to oxidative damage.

    Metabolic effects of conjugated linoleic acid in humans: the Swedish experience. Riserus U, Smedman A, Basu S, Vessby B. Am J Clin Nutr. 2004 Jun;79(6 Suppl):1146S-1148S. PMID: 15159248 CONCLUSIONS CLA and specifically the isolated isomers are interesting model fatty acids for studies of the effects of (structural differences of) unsaturated fatty acids in humans. Today, there is no clear indication for human use of CLA concentrates. The possible importance of the small reduction of body fat after supplementation with the commercially available CLA products, without evidence of an associated improvement in the metabolic profile, has to be weighed against the apparent reduction of HDL cholesterol and an increased lipid peroxidation. The possible health consequences of prolonged treatment periods are at present unknown. Human supplementation with high doses of the trans-10,cis-12 CLA isomer should be avoided while awaiting further information on possible effects and side effects. However, it cannot be excluded that future studies could point to clinical applications, eg, as a result of antitumorigenic properties or as a tool to prevent weight gain. This possibility certainly requires more research to increase the understanding of the mechanisms behind the effects of CLA and specific CLA isomers on a molecular level. More controlled studies in defined populations are needed, as are controlled studies for comparisons of the effects of different and well-defined (mixtures of) isomers and human studies of longer duration to secure long-term effects and safety.

    Effects of cis-9,trans-11 conjugated linoleic acid supplementation on insulin sensitivity, lipid peroxidation, and proinflammatory markers in obese men. Riserus U, Vessby B, Arnlov J, Basu S. Am J Clin Nutr. 2004 Aug;80(2):279-83. PMID: 15277146 CONCLUSIONS: A CLA preparation containing the purified c9,t11 CLA isomer increased insulin resistance and lipid peroxidation compared with placebo in obese men. Because c9,t11 CLA occurs in commercial supplements as well as in the diet, the present results should be confirmed in larger studies that also include women.
