The role of omega-3 fatty acids in cardiac protection: an overview. ( Front Biosci. 2005) "Fish oil has historically been thought to be good for cardiovascular health; however, data have revealed a stronger cardioprotective role of fish oil in recent years. Fish oil and specifically omega-3 fatty acids exhibit cardioprotective effects by mainly improving mortality in coronary artery disease patients. This is achieved through multiple mechanisms with the antiarrhythmic mechanism being the most prominent one. Effects on sodium and calcium channels and heart rate variability are well-accepted mechanisms of how omega-3 fatty acids exercise antiarrhythmic effects."
Chemoprevention of prostate cancer. (Crit Rev Oncol Hematol. 2005) "A major advance in prevention of prostate cancer came in 2003 with the publication of the Prostate Cancer Prevention Trial (PCPT). This overview summarizes the results of that trial, the design of other large-scale trials, and advances in understanding of the molecular mechanisms underlying the effect of other promising agents, including dutasteride, selenium, Vitamin E, Vitamin D, COX-2 inhibitors, lycopene, and green tea."
Selenium/cadmium ratios in human prostates: indicators of prostate cancer risk of smokers and nonsmokers, and relevance to the cancer protective effects of selenium. (Biol Trace Elem Res. 2005) "Selenium (Se) in a large-scale human supplementation trial has been shown to significantly reduce the incidence of prostate cancer in elderly men. Because Se is known to interact with cadmium (Cd), it has been suggested that its cancer protective action could be attributable in part to its interaction with Cd, a toxic and suspected carcinogenic element, which is found in many foods, in drinking water, and in the environment. ?
