The intervention, 'Promoting Community Conversations About Research to End Suicide' was developed by Lisa Wexler and Cris Smith at UMass Amherst with colleagues from Northwest Alaska and the University of Alaska Fairbanks. Wexler and colleagues pilot-tested the program in 10 Native Alaska communities over the past year. They've now received a five-year, $3.5 million grant from NIMH to expand the project 're-envisioning it to adapt to a new region,' as she explains.
Researchers at Emory and the Chinese Academy of Sciences analyze mice partially lacking MIR-137.
A study conducted at Texas A&M University has identified a new area in the brain involved in inhibiting fear, a discovery that holds potential for clinical interventions in patients with psychiatric diseases such as post-traumatic stress disorder (PTSD). The article was published in Nature Communications on Oct. 30.
New research focusing on how brain structure may impact brain activity and ultimately human behavior could one day lead to technology that can be catered to an individual Soldier in a training environment or operational setting.
Raven's Advanced Progressive Matrices is a widely used standardized test to measure reasoning ability. One drawback, however, is that the test takes 40 to 60 minutes to complete. Another is that the test kit and answer sheets can cost hundreds of dollars. University of California psychologists have now developed a highly comparable free test that takes 10 minutes to complete. The user-friendly test measures abstract problem-solving ability and works on tablets and other mobile devices.
HPTN 075 study demonstrates high rate of HIV infection among African men who have sex with men and transgender women. The incidence among study participants was substantially higher than the estimated incidence among heterosexual men and women in the general population in the same countries.
If approved, a monthly vaginal ring containing an antiretroviral (ARV) called dapivirine would be the first biomedical HIV prevention method specifically for women. Yet, a concern with any ARV-based method is that its use by someone who is unknowingly already infected could allow the virus to become resistant against the ARV and other drugs in the same class. New findings using highly sensitive tests suggest the risk of drug resistance with the ring is minimal.
In the first clinical study of a vaginal ring that releases the antiretroviral drug dapivirine as well as a contraceptive hormone, there were no safety concerns and the ring was well-tolerated. The ring is designed to provide protection against both HIV infection and unintended pregnancy for 90 days at a time. Given the encouraging results, researchers have already launched a second Phase I trial of the dual-purpose ring.
MIT neuroscientists present a new model of working memory that explains how the brain holds information in mind (the 'memory' part) and also executes volitional control over it (the 'working' part).
A study led by the University of Washington is the first large-scale trial of hundreds of PTSD patients, including veterans and survivors of sexual assault, to measure whether patient preference in the course of treatment impacts the effectiveness of a type of cognitive behavioral therapy and use of selective serotonin reuptake inhibitors, a type of antidepressant often prescribed for PTSD.
