Scientists from the U.S. Department of Energy’s Brookhaven National Laboratory and the University of Chicago have discovered that a member of a well-known protein family is better at detecting lead than any other known substance.
Seventh graders given 20 mg zinc, five days per week, for 10 to 12 weeks showed improvement in mental performance, responding more quickly and accurately on memory tasks and with more sustained attention, than classmates who received no additional zinc.
By combining the tools of high-throughput biology and statistical genetics, scientists at Rockefeller University, Yale University School of Public Health and the National Eye Institute have identified a gene that confers susceptibility to age-related macular degeneration (AMD), the most common cause of vision loss in the United Sates for those over 60.
Giving pregnant women in the developing world a daily supplement containing 10 vitamins and five minerals could help increase the birthweight of their babies, concludes a study published online by The Lancet.
A team of Fox Chase Cancer Center scientists led by immunologist Dietmar J. Kappes, Ph.D., has identified the genetic mutation that keeps a mouse strain from developing white blood cells, or lymphocytes, called helper T cells. The report by Kappes and his colleagues appears in the Feb. 24 issue of Nature.
Cancer researchers at Jefferson Medical College and the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia have found that zinc treatment may help prevent esophageal and oral cancers in those individuals at high risk.
According to the article, antioxidants including beta carotene, ascorbic acid, vitamin E, selenium, and zinc may prevent some of the harmful effects caused by free radicals – reactive molecules produced by metabolism in the body.
In a finding that may one day help researchers better understand age-related memory and hearing loss, scientists have shown that two key nervous system proteins interact in a manner that helps regulate the transmission of signals in the nervous system.
Duke University Medical Center researchers have shown that they can stimulate the body to produce its own naturally occurring growth factors to promote blood vessel growth into tissue damaged by peripheral arterial obstructive disease (PAOD).
Nanotechnology company pSivida has announced that its UK operating subsidiary pSiMedica Limited has been granted a further patent for BioSiliconTM.
According to Dutch researcher Pascal Groenen, a balanced diet reduces the risk of a baby with spina bifida. He investigated how different nutritional components affected the risk of developing this condition.
A large percentage of child deaths related to malaria are attributable to undernutrition and deficiencies of vitamin A, zinc, iron and folate, according to a new report by researchers with the Johns Hopkins Bloomberg School of Public Health.
Dartmouth Medical School researchers in their quest to find cures for inherited diseases have found that zinc plays a crucial role in blindness in over one million people worldwide.
The U.S. Food and Drug Administration has approved two drugs, pentetate calcium trisodium injection (Ca-DTPA) and pentetate zinc trisodium injection (Zn-DTPA) for treating certain kinds of radiation contamination. The FDA is approving these two drugs as part of its ongoing effort to provide the American public the best available protection against nuclear accidents and terrorist threats.
Research published in the current issue of the Journal of the American Heart Association, shows that antioxidant pills have no clear benefit in the prevention of cardiovascular disease.
Unlike many studies that investigate the health effects of a single chemical, the new center will study how exposure to mixtures of metals affects health—reflecting more accurately the nature of toxic waste dumps where multiple chemicals may be present.
By making use of model compounds in drug design, chemists at the University of California, San Diego identified a class of molecules that could lead to treatments for a wide range of diseases, including cancer, arthritis, and heart disease.
Eating fruit may help protect against the development of age-related maculopathy (ARM), an eye disease that can cause blindness, according to an article in the June issue of the Archives of Ophthalmology, one of the JAMA/Archives journals.
