Why do some people experience post-traumatic stress disorder (PTSD) while others who suffered the same ordeal do not? A new UCLA study may shed light on the answer.

UCLA scientists have linked two genes involved in serotonin production to a higher risk of developing PTSD. Published in the April 3 online edition of the Journal of Affective Disorders, the findings suggest that susceptibility to PTSD is inherited, pointing to new ways of screening for and treating the disorder.

*Electrical signals can’t shut off, suggest UCLA researchers*

Most of us know what it means when it’s said that someone is depressed. But commonly, true clinical depression brings with it a number of other symptoms. These can include anxiety, poor attention and concentration, memory issues, and sleep disturbances.

Traditionally, depression researchers have sought to identify the individual brain areas responsible for causing these symptoms. But the combination of so many symptoms suggested to UCLA researchers that the multiple symptoms of depression may be linked to a malfunction involving brain networks — the connections that link different brain regions.

Researchers at Yale University have developed a novel nanoparticle with promising applications in gene therapy, a type of medical treatment that addresses the root causes of diseases now typically treated for symptoms.

The advance could lead to new therapies for many forms of cancer, including brain tumors, as well as for cystic fibrosis and Huntington’s Disease. (more…)

If It’s Summer, It’s Also Scorpion Season

When stung by a scorpion, call 1-800-222-1222 and tell UA poison specialists about your symptoms.

Summer in Southern Arizona brings out the shiny auto sunshades, the supersized water bottles – and the scorpions.

The Arizona Poison and Drug Information Center, located at the University of Arizona College of Pharmacy in Tucson, reminds citizens of the desert that venomous scorpions share our habitat, and that sometimes we come closer to one another than we want. Since Jan. 1, the poison center has recorded more than 1,000 scorpion stings in its service area, which includes all counties in the state except Maricopa. (more…)

ANN ARBOR, Mich.— A non-invasive brain imaging technique gives new hope to patients with Parkinson’s disease in finding new and better treatment plans and tracking the disease progression, a new University of Michigan study shows.

The technique uses an MRI to measure resting state brain activity oscillations, said Rachael Seidler, associate professor in the School of Kinesiology and the Department of Psychology, and study author. (more…)

MSU Leads First Study of Resiliency on the Battlefield

EAST LANSING, Mich. — In the first combat-zone study of its kind, a research team led by Michigan State University found that soldiers with a positive outlook in the most traumatic situations were less likely to suffer health problems such as anxiety and depression.

The study, which surveyed Army troops fighting in Iraq, could have implications for police officers, firefighters and others who regularly deal with traumatic events such as death. Training these first-responders to think in less catastrophic terms could help them better cope with distressing events and function more effectively in the long term, said MSU’s John Schaubroeck, lead researcher on the project.

200,000 Malaria Deaths Preventable Annually, says U of T Researcher

*Deaths in India vastly underestimated*

Professor Prabhat Jha of medicine and an international team of researchers from India, Canada and the U.K. say their new studty shows the number of premature deaths from malaria in India has been vastly underestimated.

The new study is of a nationally representative sample of all deaths from any cause in India, asking family members to describe the fatal illness. Its results show that malaria accounts for about 200,000 (2 lakh) premature deaths before age 70 in India (including 80,000 children below age 15 and 120,000 adults). Previous estimates of malaria deaths were less than 10 per cent of this new figure. (more…)

COLUMBIA, Mo. – For some women, the effects of breast cancer, the most common cancer affecting women, do not end when they leave the hospital. Now, researchers in the University of Missouri School of Health Professions have studied the lives of breast cancer patients following chemotherapy and found that their environments and available support systems help determine the quality of their lives.

“A lot of times people get mentally and emotionally ready to deal with chemotherapy and they receive a lot of support during that time,” said Stephanie Reid-Arndt, an assistant professor of health psychology in the School of Health Professions. “Then they go home and everyone feels like it’s over, but the patients still have worries and fears about the changes they’ve been through and what it means for the future.” (more…)
