New tool predicts deadly form of rare cancer

Two patients with mycosis fungoides (MF) can appear to have identical diseases upon first diagnosis but can have radically different outcomes. MF in an unusual cancer of the T lymphocyte that begins in the skin rather than in the lymph nodes, with the first sign often being a rash. Most patients with MF, the most

The joy of neurons: A simplified ‘cookbook’ for engineering brain cells to study disease

Scientists at The Scripps Research Institute have devised what they call a “neuronal cookbook” for turning skin cells into different types of neurons. As reported today in the journal Nature, the research opens the door to studying common brain conditions such as autism, schizophrenia, addiction and Alzheimer’s disease under reproducible conditions in a dish. “The

Research pinpoints indicators of attraction

How can you tell if someone likes you? New research led by University of Dayton associate professor of psychology R. Matthew Montoya helps answer that question by identifying a list of nonverbal behaviors to watch for—identified by the most comprehensive analysis ever. “There is a specific suite of behaviors associated with liking, and this same

PTSD may raise odds for irregular heartbeat

(HealthDay)—For reasons that aren’t yet clear, people who battle PTSD may also be at heightened risk for the common heart rhythm disorder atrial fibrillation, researchers report. It’s the first time a connection has been made between post-traumatic stress disorder (PTSD) and “A-fib,” which typically arises with age and is the most common type of heart

Drug may reverse imbalance linked to autism symptoms

An FDA-approved drug can reverse an ionic imbalance in neurons that leads to hyper-excitability in mice modeling an autism-related genetic disorder, according to a Northwestern Medicine study published in Molecular Psychiatry. These findings suggest that the sensory hypersensitivity experienced by patients with fragile X syndrome, a syndromic autism, may be caused by elevated intracellular chloride

New insights into blood vessel growth

How new blood vessels form in mammals, for example, during development or after injury, is imperfectly understood. Scientists at Goethe University have now shed light on this process, showing that single cells in the innermost layer of blood vessels proliferate after injury, and in so doing, make a significant contribution to the formation of new

Kidney cells from amniotic fluid obtained from cesarean section at delivery

Amniotic fluid can be routinely obtained without harming the mother or the fetus. Researchers have previously demonstrated that amniotic fluid contains mesenchymal stem cells with great differentiation and regenerative potential. Importantly, amniotic fluid stem cells are immune privileged, non-carcinogenic and their potential clinical applications such as cell-replacement therapies to treat bone defects, ischemic stroke, bladder
