Two items relevant to long COVID

One of the tricky issues in studying in long COVID is: how widely do researchers cast their net? Initial reports acknowledged that people who were hospitalized and in intensive care may take a while to get back on their feet. But the number of people who had SARS-CoV-2 infections and were NOT hospitalized, yet experienced lingering symptoms, may be greater. A recent report from the United Kingdom, published in PLOS Medicine, studied more than Read more

Signature of success for an HIV vaccine?

Efforts to produce a vaccine against HIV/AIDS have been sustained for more than a decade by a single, modest success: the RV144 clinical trial in Thailand, whose results were reported in 2009. Now Emory, Harvard and Case Western Reserve scientists have identified a gene activity signature that may explain why the vaccine regimen in the RV144 study was protective in some individuals, while other HIV vaccine studies were not successful. The researchers think that this signature, Read more

Study: Regular aerobic exercise and prevention of drug abuse relapse

Exercise provides health benefits

Researchers at Emory University and the University of Georgia have received funding from the National Institutes of Health to study the neurobiological mechanisms for how regular aerobic exercise may prevent drug abuse relapse. The grant is for $1.9 million over the next five years.

David Weinshenker, PhD, associate professor of human genetics, Emory School of Medicine, is a co-principal investigator on the project.

“This research will provide new insight into how regular exercise may attenuate drug abuse in humans,” Weinshenker says “More importantly, it may reveal a neural mechanism through which exercise may prevent the relapse into drug-seeking behavior.”

During the study, Weinshenker and UGA co-investigator Philip Holmes, professor of psychology in the Franklin College of Arts and Sciences, will measure exercise-induced increases of the galanin gene activity in the rat brain.
