A 2011 study based on the trial found that the risk of prostate cancer was elevated by 17% in the group that took vitamin E supplements, which was statistically significant. [8] [13] A 2014 study based on SELECT data found that selenium supplementation increased the risk of high-grade prostate cancer in men who had a higher baseline selenium ...
Vitamin C megadosage is a term describing the consumption or injection of vitamin C (ascorbic acid) in doses well beyond the current United States Recommended Dietary Allowance of 90 milligrams per day, and often well beyond the tolerable upper intake level of 2,000 milligrams per day. [1]
Methylselenocysteine, also known as Se-methylselenocysteine, is an analog of S-methylcysteine in which the sulfur atom is replaced with a selenium atom. It is an inhibitor of DMBA-induced mammary tumors [1] and a "chemopreventive agent that blocks cell cycle progression and proliferation of premalignant mammary lesions and induces apoptosis of cancer cell lines in culture."
Selenium is found in metal sulfide ores, where it substitutes for sulfur. Commercially, selenium is produced as a byproduct in the refining of these ores. Minerals that are pure selenide or selenate compounds are rare. The chief commercial uses for selenium today are glassmaking and pigments. Selenium is a semiconductor and is used in photocells.
A former college dean who dedicated years of her life to researching a cure for cancer was gunned down on a walking trail near campus last week and her killer is still on the loose, leaving a ...
Methaneseleninic acid shows potential anticancer activity and is a model for studying the anticancer effects of selenium in vitro. [7] Methaneseleninic acid shows superior in vivo inhibitory efficacy toward human prostate cancer compared to selenomethionine or selenite (ion). [8]
The only cure for painful sickle cell disease today is a bone marrow transplant. On Tuesday, advisers to the Food and Drug Administration will review a gene therapy for the inherited blood ...
Current research suggests that the lack of selenium results in a more virulent strain of the coxsackievirus becoming the dominant viral species present in the population of virus, but the mechanism of this selection event is unclear. [4] [5] Keshan disease can also lead to higher rates of cancer, cardiovascular disease, hypertension, and strokes.
