Clues to curbing obesity found in neuronal 'sweet spot' Posted: 01 Aug 2014 06:35 PM PDT Preventing weight gain, obesity, and ultimately diabetes could be as simple as keeping a nuclear receptor from being activated in a small part of the brain, according to a new study.

Removing vending machines from schools is not enough to reduce soda consumption Posted: 01 Aug 2014 06:33 PM PDT Banning vending machines from schools can actually increase soda and fast food consumption among students if it's the only school food policy change implemented, according to new research.

Potential treatment, prevention of Parkinson's disease Posted: 01 Aug 2014 02:09 PM PDT Parkinson's disease affects neurons in the Substantia nigra brain region -- their mitochondrial activity ceases and the cells die. Researchers now show that supplying D-lactate or glycolate, two products of the gene DJ-1, can stop and even counteract this process. They also showed that the two substances rescued the toxic effects of the weed killer Paraquat. Cells that had been treated with this herbicide, which is known to cause a Parkinson's like harm of mitochondria, recovered after the addition of the two substances.

Taking the guesswork out of cancer therapy Posted: 01 Aug 2014 07:50 AM PDT Researchers have developed the first molecular test kit that can predict treatment and survival outcomes in kidney cancer patients.

Guidelines on non-cardiac surgery: Cardiovascular assessment and management Posted: 01 Aug 2014 06:12 AM PDT Worldwide, non-cardiac surgery is associated with an average overall complication rate of between 7 and 11 percent and a mortality rate between 0.8 and 1.5 percent, depending on safety precautions. Up to 42 percent of these are caused by cardiac complications. When applied to the population in the European Union member states, these figures translate into at least 167,000 cardiac complications annually, of which 19,000 are life-threatening.

Anxiety linked to seizures Posted: 01 Aug 2014 06:11 AM PDT New research by clinical psychologists from the UK and US has revealed psychogenic seizures which could be mistaken for epilepsy are linked to feelings of anxiety.

Study of bigeye tuna in Northwest Atlantic uses new tracking methods Posted: 31 Jul 2014 05:15 PM PDT Scientists have developed a new approach to study one of the most important commercial tuna species in the Atlantic, and have provided the longest available fishery-independent record of bigeye tuna movements to date. Data should help researchers to further characterize habitat use and assess the need for more monitoring in high-catch areas.

Is It Really a Concussion? Symptoms Overlap with Neck Injuries, Making Diagnosis a Tough Call Posted: 31 Jul 2014 05:09 PM PDT Athletes and others reporting cognitive difficulties after a head injury are usually diagnosed as having had a concussion. But is it really a concussion? A new study finds that many of the same symptoms are common to concussions and to injuries to the neck and/or balance system, known collectively as cervical/vestibular injuries.

Blood and saliva tests help predict return of HPV-linked oral cancers Posted: 31 Jul 2014 05:09 PM PDT Physicians have developed blood and saliva tests that help accurately predict recurrences of HPV-linked oral cancers in a substantial number of patients. The tests screen for DNA fragments of the human papillomavirus (HPV) shed from cancer cells lingering in the mouth or other parts of the body.

Commentary: It’s time to address the health of men around the world Posted: 31 Jul 2014 05:09 PM PDT All over the world, men die younger than women and do worse on a host of health indicators, yet policy makers rarely focus on this "men's health gap" or adopt programs aimed at addressing it, according to an international group of researchers and health charity workers.

See-through organs and bodies will accelerate biomedical discoveries Posted: 31 Jul 2014 11:57 AM PDT The ability to see through organs and even the entire body has been a long-time dream of biologists. A new study has now made that dream a reality, revealing simple methods for making opaque organs, bodies, and human tissue biopsies transparent, while keeping the cellular structures and connections intact. The protocols could pave the way for a better understanding of brain-body interactions, more accurate clinical diagnoses and disease monitoring, and a new generation of therapies.
