Transgenic plants remove more selenium from polluted soil than wild plants, new tests show

In the first field trial of plants genetically tweaked to absorb more contaminants, researchers found that the transgenic plants handily beat out their wild-type counterparts. The results raised hopes that the plants might become a viable alternative for cleaning up polluted soil. The new research findings, published Feb. 1 in the journal Environmental Science and Technology, show that th...

Antioxidant selenium offers no heart-disease protection

Selenium does not protect against cardiovascular disease, despite its documented antioxidant and chemopreventive properties, analysis of a randomized placebo-controlled clinical trial covering 13 years has shown. The selenium-CVD association was a secondary endpoint in the Nutritional Prevention of Cancer Trial, which was designed primarily to determine if selenium supplementation could prevent t...

Selenium-protein deficiency raises prostate cancer risk

Selenium, an essential dietary mineral that can act as an antioxidant when incorporated into proteins, has been shown in many studies to reduce the incidence of cancers -- notably lung, colorectal and prostate. "The problem is, nobody seems to know how the mechanism works, and that's not trivial," said Alan Diamond, professor of human nutrition at the University of Illinois at Chicago and...

New moth variety disarms plants guarded by selenium

In new work, researchers report that the ability of plants to defend themselves by accumulating high levels of a toxic element can be overcome by some insects, and that such adaptation potentially echoes in the food web as other predators and parasites may in turn evolve to deal with high levels of the toxic element. The findings, reported by Elizabeth Pilon-Smits of Colorado State University and...

The weight bearing joints like the hips and knees are affected in most of...

Antioxidant Selenium Offers No Major Protection against Heart-Disease

Selenium does not offer protection against cardiovascular disease, despite the lofty claims of its antioxidant and chemopreventive properties, a recent trial has shown.// The findings of the trial have been published in the April 15th issue of the American Journal of Epidemiology. Selenium now joins the club of several antioxidants, vitamins C and E in particular, that were praised for...

Prostate cancer risk pronounced with selenium-protein deficiency

Selenium, which is known for its antioxidant properties in conjunction with proteins, is also becoming popular due to its contribution in bringing down incidence// of cancers, especially lung, colorectal and prostate. "The problem is, nobody seems to know how the mechanism works, and that's not trivial," said Alan Diamond, professor of human nutrition at the University of Illinois at...

Selenium Supplements May Suppress HIV Viral Load

An article in the January 22 issue of Archives of Internal Medicine, one of the JAMA/Archives journals, shows that taking daily selenium supplements appears to increase// the level of the essential mineral in the blood and may suppress the progression of viral load in patients with HIV infection. Advances in antiretroviral therapy (ART) have given HIV patients a longer life expectancy...

Selenium Supplements May Slow Progression of HIV: Report

University of Miami researchers report that supplements of the mineral selenium appear to reduce or slow the progression of HIV. // Deficiencies in selenium have been noted in HIV-positive patients, and evidence suggests that supplements of the nutrient can improve immune system function, the researchers report in the Jan. 22 issue of the Archives of Internal Medicine. "Those...
