Brief exposure to performance-enhancing drugs may be permanently 'remembered' by muscles Posted: 27 Oct 2013 05:56 PM PDT Brief exposure to anabolic steroids may have long lasting, possibly permanent, performance-enhancing effects, shows a new study.

Eleven new genetic susceptibility factors for Alzheimer's disease discovered through the largest study Posted: 27 Oct 2013 03:53 PM PDT The largest international study ever conducted on Alzheimer's disease (AD), the I-GAP (International Genomics Alzheimer's Project) consortium has identified 11 new regions of the genome involved in the onset of this neurodegenerative disease. This study gives an overview of the molecular mechanisms underlying the disease, opening up to a better understanding of the pathophysiology of AD.

Cell nucleus protein in brown fat cells governs daily control of body temperature Posted: 27 Oct 2013 03:50 PM PDT Body temperature follows a 24-hour rhythm, peaking during the day, low at night. The benefit might be the conservation of energy while sleeping. It is also critical to be able to adapt to changes in ambient temperature regardless of the time of day. A new mouse study shows how body temperature rhythms are synchronized while maintaining the ability to adapt to changes in environmental temperature day or night.

Smart neurons: Single neuronal dendrites can perform computations Posted: 27 Oct 2013 11:06 AM PDT When you look at the hands of a clock or the streets on a map, your brain is effortlessly performing computations that tell you about the orientation of these objects. New research has shown that these computations can be carried out by the microscopic branches of neurons known as dendrites, which are the receiving elements of neurons.

Novel mutations define two types of bone tumor: Two related genes underlie the development of two rare bone tumors in nearly 100 per cent of patients Posted: 27 Oct 2013 11:06 AM PDT Scientists have made a rare discovery that allows them to attribute two types of tumour almost entirely to specific mutations that lie in two related genes.

Stroke prevention surgery less effective than meds, lifestyle change Posted: 26 Oct 2013 01:49 PM PDT The final results of a stroke prevention study in patients with narrowed brain arteries confirm earlier findings: Medication plus lifestyle changes are safer and more effective at preventing stroke than a surgical technique called stenting.

Only 11 percent of children involved in bike accidents wear a helmet Posted: 26 Oct 2013 06:11 AM PDT Despite a California bike helmet mandate, only 11 percent of Los Angeles County children treated for bike-related injuries were wearing a helmet, according to new research.

Pediatric musculoskeletal MRSA infections on the rise Posted: 26 Oct 2013 06:11 AM PDT Pediatric musculoskeletal Staphylococcus aureus bacterial infections have been evolving over the past decade, with more children diagnosed with the more virulent, methicillin-resistant Staphylococcus aureus (MRSA) today than 10 years ago. The result is longer hospitals stays, more surgeries and other related complications, according to new research.

Enzyme restores function with diabetic kidney disease Posted: 25 Oct 2013 03:56 PM PDT Researchers say that, while a prevailing theory suggests elevated cellular levels of glucose ultimately result in diabetic kidney disease, the truth may, in fact, be quite the opposite. The findings could fundamentally change understanding of how diabetes-related diseases develop – and how they might be better treated.

Positive personal growth following breast cancer diagnosis Posted: 25 Oct 2013 12:52 PM PDT Although being diagnosed with breast cancer is usually an extremely stressful experience for most women, a new study by researchers has found that there also can be unexpected benefits.

Study reveals first effective medicine to treat cocaine dependence Posted: 25 Oct 2013 08:37 AM PDT New research reveals that topiramate, a drug approved by the U.S. Food and Drug Administration to treat epilepsy and migraine headaches also could be the first reliable medication to help treat cocaine dependence.
