Selenium is a trace element crucial to life - too little or too much of it is fatal. In the July 17 issue of the journal Science, researchers at Yale University and University of Illinois at Chicago detail the molecular mechanisms that govern its metabolism in the human body. "It must require an intricately regulated uptake system," said Dieter Söll, co-senior author of the paper, Sterling Professor of Molecular Biophysics and Biochemistry at Yale. "There are 25 human selenoproteins, and...

A U.S. biologist says the accumulation of metals in plants may be a strategy to protect the plants from predators such as prairie dogs. Postdoctoral researcher John Freeman of Colorado State University and colleagues said certain plant species growing on soils with high metal content, such as arsenic, copper, selenium or lead, accumulate large quantities of metals in their leaves and stems. The purpose of that hyperaccumulation isn't fully known, but Freeman said it might increase a plant's...

Higher selenium levels in the blood may worsen prostate cancer in some men who have the disease, U.S. researchers said. Researchers at Dana-Farber Cancer Institute in Boston and the University of California, San Francisco, said a higher risk of more-aggressive prostate cancer was seen in men with a certain genetic variant found in about 75 percent of the prostate cancer patients in the study. In those subjects, having a high level of selenium in the blood was associated with a two-fold...

Prairie dogs may seem like harmless little creatures, but they can inflict serious injury on plants simply by snacking on them. Plants cannot flee from their furry predators, so how do they avoid becoming a prairie dog's lunch?Dr. John Freeman and colleagues explore the role of metal hyperaccumulation in plant defense in the June 2009 issue of the American Journal of Botany. Certain plants species growing on soils with high metal content (such as arsenic, copper, selenium, and lead)...

Bayer Healthcare's claim that its One-A-Day vitamins for men reduce the risk of prostate cancer may lead to the company facing a lawsuit from a consumer advocacy group, The Associated Press reported. The company's ubiquitous TV and radio ads misleadingly claim that a key ingredient of One-A-Day Men's Health Formula and 50+ Advantage helps prevent cancer, according to the Center for Science in the Public Interest. The National Institutes of Health backed a study that found no evidence the...

A U.S. advocacy group notified Bayer Healthcare it will sue if the company continues to claim the selenium in its vitamins may reduce prostate cancer risk. David Schardt, senior nutritionist at The Center for Science in the Public Interest in Washington, said advertisements and labels for One A Day Men's 50-plus Advantage and One A Day Men's Health Formula multivitamins claim emerging research suggests selenium may reduce the risk of prostate cancer. However, leading prostate cancer...

Researchers say U.S. Food and Drug Administration methods of creating seafood consumption guidelines may not offer reliably accurate food safety assessments. University of North Dakota scientists said that when mercury levels are measured in fish, the levels of the mineral selenium also need to be considered. But since only mercury levels are presently being assessed, FDA evaluations of risk from ocean fish consumption are being overstated, and, conversely, risks from eating fresh water fish...

Many breast cancer patients undergoing treatment continue to take antioxidants, even though the consequences of taking the supplements remain unknown, a new study found. Six in 10 women reported using antioxidants while receiving chemotherapy, radiation or hormone therapy for breast cancer, and about seven in 10 antioxidant users said they used high doses, which was defined as higher than the dose contained in a Centrum multivitamin. Antioxidant supplements include vitamin C, vitamin E,...

mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
