Suicide rates in rural areas of Maryland are 35-percent higher than in the state's urban settings, a disparity that can be attributed to the significantly greater use of firearms in rural settings, according to new research from the Johns Hopkins Bloomberg School of Public Health.
Scientists have used magnetism to activate tiny groups of cells in the brain, inducing bodily movements that include running, rotating and losing control of the extremities -- an achievement that could lead to advances in studying and treating neurological disease.
Older people receiving electroconvulsive therapy for their depression likely will need an additional treatment if insomnia is one of their symptoms, researchers report.
Scientists have located two areas in the brain that help us recognize familiar faces. The discovery will help them delve deeper into the relationship between face recognition, memory, and social knowledge.
New McLean Hospital research, using a mouse model simulating human bullying, suggests that being bullied produces long-lasting, depression-like sleep dysfunction and other effects on daily biological rhythms
Fragile X syndrome, caused by a disruption of the gene FMR1, is the most common inherited form of intellectual disability. Emory scientists have revealed new aspects of the function of FMR1 and a 'friend' -- called ZC3H14 in humans/mice and dNab2 in flies.
A recent study by Penn Medicine researchers published online ahead of print in the Journal of the American Academy of Child & Adolescent Psychiatry found that the costs associated with the Early Start Denver Model (ESDM), one evidence-based treatment for young children with autism, were fully offset after only two years following intervention due to reductions in children's use of other services.
The dapivirine vaginal ring, which had been found safe and to help protect against HIV in two Phase III trials in African women, was shown to be safe and acceptable in a study of US teen girls. Regulatory approval is being sought for the ring in women ages 18-45; the new study provides data that would be needed for expanding approval to include girls under age 18, one of the highest-risk groups in Africa.
Researchers at the University of Chicago have demonstrated, for the first time, that a key protein complex in the brain is linked to the ability of young animals to learn behavioral patterns from adults. The findings, published July 24 in the Proceedings of the National Academy of Sciences, show that a specific neural signal -- the mechanistic Target of Rapamycin (mTOR) cascade -- regulates the ability of juvenile zebra finches to form accurate memories of songs taught to them by adult birds.
The antiretroviral drug dapivirine contained in a vaginal ring for HIV prevention, is absorbed in very low concentrations into breastmilk, according to a US study of the dapivirine ring in women who were no longer nursing their babies but still producing milk. Researchers are now planning studies of the ring in African women who are breastfeeding as well as during pregnancy, when there may be a greater risk of acquiring HIV.
