A recent study examined injection risk behaviors among heroin injectors in the Colombian cities of Medellín and Pereira to explore the implications for possible increased HIV transmission within PWID.
Why do we remember some events, places and things, but not others? Our brains prioritize rewarding memories over others, and reinforce them by replaying them when we are at rest, according to new research from the University of California, Davis, Center for Neuroscience, published Feb. 11 in the journal Neuron.
Scientists from the Florida campus of The Scripps Research Institute have won nearly $1.7 million from the National Institutes of Health's National Institute of Neurological Disorders and Stroke to investigate the mechanisms that contribute to Huntington's disease, a fatal inherited disease that some have described as having ALS, Parkinson's and Alzheimer's -- at the same time.
Scientists from The Wistar Institute have shown that one gene that was once thought only to be found in the brain is also expressed in breast cancer and helps promote the growth and spread of the disease. Additionally, they showed how a version of the gene with edited RNA prevents metastasis.
Men have many reasons to add high-impact and resistance training to their exercise regimens; these reasons include building muscle and shedding fat. Now a University of Missouri researcher has determined another significant benefit to these activities: building bone mass. The study found that individuals who continuously participated in high-impact activities, such as jogging and tennis, during adolescence and young adulthood, had greater hip and lumbar spine bone mineral density than those who did not.
A new imaging technique has allowed researchers to see how DNA loops around a protein that aids in the formation of a special structure in telomeres.
Scientists from the Monell Center have further characterized the identity and functionality of salt-responding taste cells on the tongue. The knowledge may lead to novel approaches to develop salt replacers or enhancers that can help reduce the sodium content of food while retaining desirable salty taste.
The team researched a quasi-random assignment of 84 ACHIEVEability participants to their housing units. Investigators evaluated whether micro-neighborhood environments -- the group of city blocks immediately surrounding housing units -- affected participants' progress in achieving college credits. The study found that participants did succeed in their educational pursuits in line with program requirements, earning about 12 college credits per year, but the characteristics of the neighborhood in which the subsidized housing was located did affect this progress.
Higher intake of foods containing vitamin D during pregnancy -- but not supplemental vitamin D intake -- was associated with reduced risk of development of allergies in children.
Scientists at Wake Forest Baptist Medical Center have found that a daily dose of beetroot juice significantly improved exercise endurance and blood pressure in elderly patients with heart failure with preserved ejection fraction (HFPEF).
