Common properties in genes implicated in the development of cancer

Two researchers from the University of Navarra, Javier Novo and Josť Luis Vizmanos, have performed a bioinformatic study on which genes have been implicated in the development of cancer. The research project has been described in an article which will be published shortly in Trends in Genetics. more  

Experience backs early heart valve replacement

Patients with leaky aortic heart valves appear to do better when the valves are replaced before significant symptoms develop, as recommended by the American College of Cardiology/American Heart Association guidelines, according to a new study in the Mar. 7, 2006, issue of the Journal of the American College of Cardiology. more

Mental stress effects on heart more common than previously known

Even when heart disease patients can pass stress tests done on a treadmill or with chemical stressors after treatment, their hearts may still suffer silent ischemia during mental stress, according to a new study in the Mar. 7, 2006, issue of the Journal of the American College of Cardiology. more  

Declines in exercise capacity may be due to lack of training, not just age

Older people generally have to work harder than younger people to walk as fast or do other exercise, but some of the difference may be due to reduced exercise efficiency, which can be reversed with training, according to a new study in the Mar. 7, 2006, issue of the Journal of the American College of Cardiology. more

Sex chromosome genes influence aggression, maternal behavior, say UVa researchers 

It has been well documented that, across human cultures and in most mammals, males are usually more aggressive and less nurturing than females. Itís simple to blame male hormones, like testosterone, for male behavior such as aggression. But maybe itís in our genes, too. more

Study indicates dramatic rise in antibiotic-resistant community-acquired staph infections  

Staph infections resistant to antibiotics, previously only associated with hospitalization or prior contact with the healthcare system, are now widespread in the community and coming home. A new study from Emory University School of Medicine and Grady Memorial Hospital, featured in the March 7, 2006 Annals of Internal Medicine, reports on a dramatic rise in antibiotic resistant community-acquired methicillin-resistant Staphylococcus aureus (MRSA), making it the primary cause of skin and soft tissue infections. An editorial accompanying the article notes, "the number of populations at risk for community-acquired MRSA infections is steadily expanding", making it a "remarkable epidemic." more

Repeated test-taking better for retention than repeated studying, research shows

Despite their reputation as a cruel tool of teachers intent on striking fear into the hearts of unprepared students, quizzes ó given early and often ó may be a student's best friend when it comes to understanding and retaining information for the long haul, suggests new psychology research from Washington University in St. Louis. more
