Popular antidepressant might prevent heart failure Posted: 01 Oct 2012 12:47 PM PDT A medication usually used to help treat depression and anxiety disorders has the potential to help prevent heart failure, according to researchers at the University of Michigan. read more

Fluoxetine increases aggressive behavior, affects brain development among adolescent hamsters Posted: 01 Oct 2012 11:05 AM PDT Fluoxetine was the first drug approved by the FDA for major depressive disorder (MDD) in children and adolescents, and to this date, it remains one of only two selective serotonin reuptake inhibitors (SSRIs) registered for treatment of MDD in children and adolescents, despite reports that indicate this class of drugs is associated with side effects, such as agitation, hostility and aggression. read more

Zinc deficiency mechanism linked to aging, multiple diseases Posted: 01 Oct 2012 11:01 AM PDT A new study has outlined for the first time a biological mechanism by which zinc deficiency can develop with age, leading to a decline of the immune system and increased inflammation associated with many health problems, including cancer, heart disease, autoimmune disease and diabetes. read more

Omega-3 Supplements May Slow A Biological Effect of Aging Posted: 01 Oct 2012 10:53 AM PDT Taking enough omega-3 fatty acid supplements to change the balance of oils in the diet could slow a key biological process linked to aging, new research suggests. The study showed that most overweight but healthy middle-aged and older adults who took omega-3 supplements for four months altered a ratio of their fatty acid consumption in a way that helped preserve tiny segments of DNA in their white blood cells. read more

How sexual power can be disempowering Posted: 01 Oct 2012 08:55 AM PDT Gender roles and norms play a key role in sexual behavior between men and women. It is often assumed that men should dominate women sexually. This assumption may lead to loss of both power and the ability to control sexual behavior among women and men, as well as lead to increased sexual risk-taking, such as not using a female condom. The new study, by Dr. Lisa Rosenthal from Yale University in the US, and her colleagues, is published online in Springer's journal Sex Roles. read more

Predatory bacterial crowdsourcing Posted: 01 Oct 2012 08:40 AM PDT Move forward. High-five your neighbor. Turn around. Repeat. That’s the winning formula of one of the world’s smallest predators, the soil bacteria Myxococcus xanthus, and a new study by scientists at Rice University and the University of Texas Health Science Center at Houston (UTHealth) Medical School shows how M. xanthus uses the formula to spread, engulf and devour other bacteria. bacterial waves read more

Researchers Halt Autoimmune Disease Myasthenia Gravis in Mice Posted: 01 Oct 2012 08:30 AM PDT Working with mice, Johns Hopkins researchers say they have developed a gene-based therapy to stop the rodent equivalent of the autoimmune disease myasthenia gravis by specifically targeting the destructive immune response the disorder triggers in the body. The technique, the result of more than 10 years of work, holds promise for a highly specific therapy for the progressively debilitating muscle-weakening human disorder, one that avoids the need for long-term, systemic immunosuppressant drugs that control the disease but may create unwanted side effects. read more

Eliminating Visual Clutter Helps People with Mild Cognitive Impairment Posted: 01 Oct 2012 08:23 AM PDT A new study from Georgia Tech and the University of Toronto suggests that memory impairments for people diagnosed with early stage Alzheimer’s disease may be due, in part, to problems in determining the differences between similar objects. The findings also support growing research indicating that a part of the brain once believed to support memory exclusively – the medial temporal lobe - also plays a role in object perception. The results are published in the October edition of Hippocampus. read more
