Research Extras

The Coulter Department of Biomedical Engineering at Georgia Tech and Emory University has named Ravi V. Bellamkonda as chair.

NIH Director Francis Collins recently visited Emory to discuss the importance of NIH funding, along with Georgia Congressman Jack Kingston and staff and top researchers from other Georgia universities. Collins called Georgia a "hotbed of great science and wonderful interactive research from basic to clinical."

The first human exposome-based center grant from the NIH has established the HERCULES Center (Health and Exposome Research Center: Understanding Lifetime Exposures) at Emory's Rollins School of Public Health, along with partners at Georgia Tech.

Emory and the Atlanta VA Medical Center are participating in a new NIH study comparing the long-term benefits and risks of four widely used type 2 diabetes drugs in combination with the first-line drug metformin.

A new research study is using virtual reality exposure therapy to treat an incapacitating fear of flying, but with the addition of a trigger, or cue, before each cognitive behavioral therapy session to help prevent relapse.

PTSD Treatmant

PTSD risk could be lower with new compound
A compound that targets several of the same brain receptors affected by morphine could reduce PTSD after stress exposure. The discovery in mice meshes with recent studies hinting that morphine given after traumatic injury may lower PTSD risk. Scientists hope the compound, called SR-8993, could lead to a drug therapy to prevent PTSD after trauma. Read more...

Childern at risk for autism

Blood test for autism gauges genetic risk factors
Researchers hope a new blood test could identify children at an early age who are at risk for autism spectrum disorders. The test measures levels of RNA gene expression. Results from a new clinical trial will be compared with current measures of clinical diagnosis. The current average age of diagnosis for autism is 4.5 years, but behavioral therapies are much more successful when started earlier. Read more...

White Matter

White matter imaging gives insight into brain aging in humans and chimpanzees
Brain imaging studies have shown that white matter – the wires connecting the computing centers of the brain – begins to deteriorate earlier in the human lifespan than in the lives of aging chimpanzees. Humans' longer lives and distinctive metabolism could lie behind the differences in the patterns of brain aging. Read more...

Predicting heart disease

Biomarker trio predicts near-term heart risk
Cardiologists have found three biomarkers that may predict which heart disease patients have a high risk of heart attack or death within the next two years. The annual risk is more than five times greater for those in the highest risk group vs. those in the lowest risk group. The new risk score contrasts with the Framingham Risk Score, which calculates someone’s risk of developing heart disease over the next 10 years. Read more...

tPA as brain protector

A new role for tPA as brain protector
The clot-busting drug tPA has been considered a "double-edged sword" for stroke patients because it can help restore blood flow to the brain but also can increase bleeding risk. New research shows even when its clot-dissolving powers are removed, tPA can still protect brain cells from the loss of oxygen and glucose induced by a stroke. A modified version of tPA could benefit patients without increasing risk of hemorrhage. Read more...
