Medical Xpress / Plasticizer exposure during pregnancy linked to increased autism- and ADHD-related symptoms in children
The foundations of brain development are laid during a crucial period of pregnancy, and a common household plasticizer called DEHP may be quietly interfering with this process. Scientists have now found that prenatal exposure ...
Medical Xpress / Smooth-gradient fMRI technique could improve brain mapping during behavior
Neuroscientists and medical researchers now have a wide range of imaging techniques to study the brain and its activity. One of the most widely used is functional magnetic resonance imaging (fMRI), a noninvasive technique ...
Medical Xpress / Autism-risk mutations reveal two opposing patterns of brain gene activity
Autism spectrum disorder (ASD) is associated with more than 1,200 risk genes, raising a fundamental question: Do these diverse genetic changes affect the brain in entirely different ways, or do they converge on shared biological ...
Medical Xpress / New MRI measure reveals how closely blood flow matches brain cells' energy needs
Researchers from the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have developed a new, noninvasive way to examine how blood flow and cellular organization ...
Medical Xpress / Gut microbe molecule reveals molecular link between microbiome and whole-body metabolism
Researchers at the University of Konstanz have demonstrated at a molecular level how bacteria in the human gut influence the entire body. Among other things, they can lower blood sugar levels and reduce fatty liver disease. ...
Medical Xpress / Teaching the immune system to control HIV
There is no cure for HIV. While scientists have made considerable progress in controlling the infection, patients still must take daily antiretroviral medication for the rest of their lives. Results from a clinical trial ...
Medical Xpress / REM and deep sleep, not just total sleep time, associated with disease risk
Greater amounts of REM and deep sleep were associated with lower risks of dozens of diseases, and less than 5 hours of total sleep was associated with high disease risks, according to a new study published Sept. 17 in the ...
Medical Xpress / Rare inherited EGFR mutation linked to dramatically increased lung cancer risk
A rare inherited mutation in the Epidermal Growth Factor Receptor (EGFR) gene is associated with a 25-fold increased risk of lung cancer, according to a study by investigators at Dana-Farber Cancer Institute and 23andMe Research ...
Medical Xpress / Gestures influence the way our brains process grammar
Our hands may do more than complement what we say. They can also help our brains process grammar. In a new neuroimaging study published in PNAS, researchers from the Max Planck Institute for Psycholinguistics (MPI) in Nijmegen ...
Medical Xpress / The body's warmth sensor is secretly a pain switch—blocking it may ease arthritis
Chronic pain, including arthritis pain, affects more than one-third of U.K. adults. Current painkillers such as methotrexate and nonsteroidal anti-inflammatory drugs (NSAIDs) work by damping down the immune system, which ...
Medical Xpress / Intermittent fasting shows promise in slowing Huntington's disease progression
A simple change in when people eat may offer a promising new approach for Huntington's disease, according to research led by Oregon Health & Science University.
Medical Xpress / AI tool nears psychiatrist-level accuracy
UTHealth Houston researchers have developed an artificial intelligence system that can perform a mental health evaluation at nearly the same level of accuracy as a team of psychiatrists. The results of their work, done in ...
