News from the world of medicine:
Researchers have demonstrated that an antibiotic called "monensin" prevents the growth of prostate cancer cells. Evidenceemerged in a project investigating the effects of nearly 5,000 drugs and micromolecules on the growth of prostate cancer cells. Researchers found that small amounts of compounds -- disulfiram (Antabus), thiram, tricostatin A, and monensin -- can prevent the growth of prostate cancer cells without significant effects on the growth of the normal human prostate epithelial cells.
Researchers at Harvard have identified a substance found primarily in dairy fat that appears to lower the risk of type 2 diabetes. Known as trans-palmitoleic acid, it is present in the fat of ruminant animals such as cows, sheep, and goats. In the Harvard study, people with the highest levels of the fatty acid in their blood had a threefold lower risk of developing diabetes over time than people with the lowest levels. They also had healthier HDL, or good, cholesterol levels, lower body fat, and less insulin resistance.
The vitamin D levels of newborn babies appear to predict their risk of respiratory infections during infancy and the occurrence of wheezing during early childhood, but not the risk of developing asthma. The results support the theory that widespread vitamin D deficiency contributes to risk of infections.
Despite its popularity as a natural remedy for treating the common cold, a new study suggests echinacea does not substantially reduce the severity or duration of the common cold.
Women with breast cancer who take multivitamins with minerals appear to face lower odds of having their cancer come back or dying. "Multivitamins appears to especially benefit women undergoin gradiation treatment," says researcher Heather Greenlee, ND, PhD, of Columbia University's Herbert Irving Comprehensive Cancer Center in New York City. The study doesn't prove cause and effect. The association could be explained by other factors.
