Medical Xpress / Single hair strand could provide biomarker for amyotrophic lateral sclerosis
Researchers at the Icahn School of Medicine at Mount Sinai have shown for the first time that a single strand of hair can reveal unique elemental patterns that distinguish people with amyotrophic lateral sclerosis (ALS) from ...
Medical Xpress / How an autism-linked mutation reduces vasopressin and alters social behavior
A team of researchers has identified for the first time the mechanism linking a mutation in the Shank3 gene with alterations in social behavior. Using a mouse model carrying this autism-associated mutation, the study shows ...
Medical Xpress / Activating brown fat may yield a new strategy to tackle obesity
Is it possible to treat obesity without reducing food intake? A new study co-led by Dr. Antonio Zorzano and Dr. Manuela Sánchez-Feutrie at the Institute for Research in Biomedicine (IRB Barcelona) suggests that this might ...
Medical Xpress / Inflammation jolts 'sleeping' cancer cells awake, enabling them to multiply again
Cancer cells have one relentless goal: to grow and divide. While most stick together within the original tumor, some rogue cells break away to traverse to distant organs. There, they can lie dormant—undetectable and not ...
Medical Xpress / Gene variant slows down removal of debris in the brain, increasing Alzheimer's risk, say researchers
A type of brain cell that plays a vital role in maintaining neural networks and repairing injuries lies at the core of a promising new study on Alzheimer's disease from the USF Health Byrd Alzheimer's Center and Research ...
Medical Xpress / Researchers reveal potential molecular link between air pollutants and increased risk of Lewy body dementia
A team of researchers at Johns Hopkins Medicine say they have revealed a possible molecular connection between air pollution and an increased risk of developing Lewy body dementia.
Medical Xpress / How brain fluid dynamics drive cancer spread—and ways to fight back
New research has uncovered how cerebrospinal fluid dynamics in the brain play an important role in driving the spread of medulloblastoma, the most common malignant brain tumor in children.
Medical Xpress / Dietary changes could provide a therapeutic avenue for brain cancer
Glioblastomas are the deadliest form of malignant brain tumor, and most patients diagnosed with the disease live only one or two years. In these tumors, normal cells in the brain become aggressive, growing rapidly and invading ...
Medical Xpress / Study shows how smoking drives pancreatic cancer
A new study explains why smokers have a higher chance of developing pancreatic cancer and why they tend to have worse outcomes than nonsmokers.
Medical Xpress / Microscopic pores in brain cells may be key to understanding Parkinson's
A toxic protein forms dynamic pores in the membranes of brain cells—and that may be the key to understanding how Parkinson's disease develops. This is the conclusion of a new study from Aarhus University, where researchers ...
Medical Xpress / After early-life stress, astrocytes can affect behavior
Astrocytes in the lateral hypothalamus region of the brain, an area involved in the regulation of sleep and wakefulness, play a key role in neuron activity in mice and affect their behavior, Canadian researchers have found.
Medical Xpress / Scientists look to commercial dyes to help them diagnose dementia
Today, when an aging parent, relative, or friend starts to forget things, a firm diagnosis can be surprisingly elusive.
