Study provides new evidence of the importance of reward pathways in the brain

Deleting a specific gene in the brain has the same effect that antidepressants do in mice that have been conditioned to be depressed, report researchers at UT Southwestern Medical Center.

Research points to a novel approach to treating serious Strep infections

Researchers at the University of California, San Diego (UCSD) School of Medicine have discovered that so-called flesh-eating "Strep" bacteria use a specific enzyme to break free of the body's immune system, a finding which could potentially lead to new treatments for serious infections in human patients.

SRY protein explains why men more likely to develop Parkinson's

Scientists at Prince Henry's Institute, Melbourne, and the University of California, Los Angeles, have discovered that SRY, the male protein that forms the testes is also produced in the brain region affected in Parkinson's disease.

PET and MR imaging reveals white matter degeneration in Huntington's

Using both brain function (PET) and anatomical structure (MR) imaging studies, Italian researchers - within the context of an Italian-British collaboration - discovered that degenerative and dysfunctional events occur in individuals many years before the onset of Huntington's disease - particularly in the brain's white matter - an area not previously considered primarily involved with the disease.

Scientists discover genetic profile eosinophilic esophagitis

Though many parents may never have heard of it, a severe and chronic condition called eosinophilic esophagitis (EE) is recognized by doctors as an emerging health problem for children.

New report suggests promising strategies to preserve brain health as people grow older

With the rapid aging of the population, the National Institutes of Health (NIH) is intensifying the search for strategies to preserve brain health as people grow older.

Alcoholism, smoking and genetics among Plains American Indians

Alcoholism and smoking have a high rate of co-occurrence in the general population. Yet little is known about the co-morbidity of alcoholism and smoking among American Indians.

Genetic variations help predict risk for salt-induced high blood pressure

Researchers led by UVa Health System pathologist Robin Felder, Ph.D., have demonstrated that looking for several variations of genes that control blood pressure can predict the risk for high blood pressure caused by high levels of salt.

Discovery of mechanisms responsible for the difference in immune response between male and female mice

The differences in the male and female immune responses, which make females more prone to autoimmune disease and males more subject to infections, are established during puberty.

Discovery of molecule that may hold key to learning and memory

Independent research teams from Harvard Medical School and Children's Hospital Boston have identified a master protein that sheds light on one of neurobiology's biggest mysteries--how neurons change as a result of individual experiences.

SRY gene directly controls neuronal function in the brain

Shaped by much previous research, the prevailing view regarding sex-specific differences in the brain is that they are caused by circulating sex hormones, which are generated outside the brain and influence certain aspects of brain development, as well as brain function in adults.

Ebola DNA vaccine shows promise

Vical Incorporated has announced that an Ebola vaccine candidate administered using Vical's proprietary DNA delivery technology was safe and well tolerated, and produced both antibody and T-cell Ebola-specific responses in all healthy volunteers who received the full 3 doses of vaccine.

Lifetime calorie restraint to prevent obesity is the most powerful way to reduce age-related health problems

University of South Florida researcher Barbara Hansen, PhD, will likely never be invited to talk about weight loss on Oprah. Her message is mundanely common sense, not faddish - she doesn't drop phrases like "low carb," or "low fat," or "geared to your body type" or "put your body into fat-burning mode."

Researchers create animal model of any schizophrenic characteristics

Researchers have developed a mouse strain in which the abnormal activity of the dopamine machinery in a specific part of the brain causes cognitive and behavioral impairments mimicking those in human schizophrenics.
