Athens, Ga. — New University of Georgia research has found that a statin drug that is often known by the brand-name Lipitor may help prevent blindness in people with diabetes.
In a study using diabetic rats, lead author Azza El-Remessy, assista…
Philadelphia, PA, 15 November 2010 – A family history of Alzheimer’s disease significantly increases the risk for developing this disorder, but a new study in Biological Psychiatry suggests that which of your parents has the disease is very importan…
People with high levels of iron in their diet are more likely to develop Parkinson’s disease, according to a study in the June 10 issue of Neurology. People with both high levels of iron and manganese were nearly two times more likely to develop the disease than those with the lowest levels of the minerals in their diets. The study compared 250 people who were newly diagnosed with Parkinson’s to 388 people without the disease. Interviews were conducted to determine how often participants ate certain foods during their adult life.
Studies conducted at Pace University have indicated that green tea extracts (GTE) and polyphenol (PP) have an adverse effect on bacteria that cause strep throat, dental caries, and other infections. Additionally, the research suggests that the oral agents such as toothpaste and mouthwash are more effective in fighting pathogenic microbial agents, such as viruses, with the addition of GTE and PP. Researchers present their findings today at the 103rd General Meeting of the American Society for Microbiology.
The structure of a key energy-releasing enzyme found in all animals is designed to minimise free radical production, an international team of researchers has reported in the journal Science. In a startling feat of structural biology, the team visualised the entire molecular structure of succinate dehydrogenase in the bacterium E. coli, allowing them to see for the first time how the protein’s three-dimensional shape helps prevent the formation of large quantities of these destructive oxygen atoms.
Boosting insulin with vitamins C and E may improve the drug’s effectiveness for treating diabetes. A UC Irvine College of Medicine study has found that the popular antioxidant supplements not only enhance insulin’s ability to reduce blood sugar, but also lower the risks of organ damage that can occur despite insulin treatments. The study appears in the January issue of Kidney International.
Scientists at St. Jude Children’s Research Hospital have discovered a novel biochemical process that plays a critical role in helping cells in the body respond to DNA damage, such as that caused by exposure to radiation, environmental toxins or free radicals. The findings could lead to new approaches to prevent cancer, better ways to treat cancer and to the development of sensitive methods determining whether people have been exposed to radiation or environmental toxins, according to the researchers.
Grape-seed extract may help skin wounds heal faster and with less scarring, a new study suggests. The extract seemed to aid wound healing in two ways: It helped the body make more of a compound used to regenerate damaged blood vessels, and it also increased the amount of free radicals in the wound site. Free radicals help clear potentially pathogenic bacteria from a wound.
