In a fresh study.

In a fresh study, scientists may have found a culprit: a significant scarcity of nitric oxide, a little molecule essential in the regulation of blood flow and blood pressure. The research team, led by Ohio University biochemist Tadeusz Malinski, examined the bloodstream vessel cells of 12 white and 12 black healthy female subjects. Using a operational system of nanosensors, they found that the cardiovascular systems of African-American subjects as youthful as twenty years old could show signals of an unbalanced nitric oxide program that could become significantly worse as they grow older, according to research published in a recently available issue of Circulation, a journal of the American Center Association.The researchers noted that environment plays a substantial role. For instance, the genes that fix DNA might be able to help repair a few of the damage due to an environmental factor, such as smoking. But when too much harm accumulates, it causes cells to die, the experts said. Previous research shows that women who smoke cigarettes enter typically one to two years earlier menopause, the researchers noted. Dr. Kutluk Oktay, director of the Division of Reproductive Institute and Medication for Fertility Preservation at NY Medical College in Valhalla, N.Y., known as the research significant, and said it expands on previous studies by his team that supplied insight into genes and childbearing in females.
