For the first time scientists have been able to film, in real time, the nanoscale interaction of an enzyme and a DNA strand from an attacking virus. Researchers from the University of Cambridge have used a revolutionary Scanning Atomic Force Microscope in Japan to produce amazing footage of a protective enzyme unravelling the DNA of a virus trying to infect a bacterial host.
A University of Minnesota study of prostate cancer tumors from Caucasian and African-American men has shown no evidence that the cancer is more aggressive in black men. Lead investigator Akhouri Sinha, a professor of genetics, cell biology, and development and research scientist at the Minneapolis VA Medical Center, said the belief that black men’s tumors are more aggressive is based on studies that failed to match patients properly and used only indirect means to measure tumor aggressiveness.
In a new randomized controlled trial, both aerobic and resistance exercise improved glycemic/blood sugar control in people with type 2 diabetes. The greatest improvements came from combined aerobic and resistance training.
A group of interns of the Teaching Maternity Unit of the University College of Health Care of the UGR has carried out a bibliographic review of the shaken baby syndrome. Many of the diagnosed cases which produce internal damage to the infant have been caused by mistreatment or abuse.
Although prescription medications that may increase the risk of birth defects are commonly used by women in their childbearing years, only about half receive contraceptive counseling from their health care providers, according to a large-scale study from the University of Pittsburgh School of Medicine reported in the Sept. 18 issue of the Annals of Internal Medicine.

Men in late middle age with depressive symptoms are more likely to leave the labor force than men without such symptoms are, according to a new study from the University of Pennsylvania.
Air pollution could be putting patients with heart disease at risk by affecting blood vessels and clotting, researchers warn. A study by the University of Edinburgh and Umeå University measured the effects of diesel exhaust on heart and blood vessel function in men who have previously experienced a heart attack.
Having a healthy kidney is worth a billion dollars. But an unhealthy kidney costs more—about $16 billion more, according to Prabir Roy-Chaudhury, MD, PhD, associate professor in the division of nephrology and hypertension at the University of Cincinnati (UC).
A human peptide that acts as a natural antibiotic against invading microbes can also bind to the body’s own DNA and trigger an immune response in the absence of an infection, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in an early online publication in Nature.
