THURSDAY, Aug. 9, 2018 — Evolutionary changes in the human brain may be responsible for psychiatric illnesses such as schizophrenia and bipolar disorder, new research suggests. The researchers identified long, noncoding stretches of DNA (called “repeat arrays”) in a gene that governs calcium transport in the brain. Their findings were published Aug. 9 in the […]
A one-two punch of powerful antibodies may be the best way to stop Ebola virus, reports an international team of scientists in the journal Cell. Their findings suggest new therapies should disable Ebola virus’s infection machinery and spark the patient’s immune system to call in reinforcements. “This study presents results from an unprecedented international collaboration […]
Scientists in Japan have found a potential marker to identify which people with abnormally fast heartbeats are at high risk of developing heart failure. The results were published in June in Circulation: Genomic and Precision Medicine, a journal from the American Heart Association. Atrial fibrillation, or chronically, abnormally fast heartbeat, can be a symptom of […]
There is new hope for the treatment of Alzheimer’s and other neurological diseases following a ground-breaking discovery made by an Australian-Chinese research collaboration. Researchers from the University of South Australia and the Third Military Medical University in China have discovered a signal pathway within cells, and also invented a potential drug that could stop degeneration […]
(HealthDay)—Walking is associated with improved quality of life (QoL) among those at risk for or living with cardiovascular disease (CVD), according to a study published in PLoS One. Viviane de Menezes Caceres, from the University of Adelaide in Australia, and colleagues investigated whether physical activity (PA) of different intensity and duration moderates the relationship between […]
Alzheimer’s disease is difficult to diagnose as well as treat, but researchers now have a promising new screening tool using the window to the brain: the eye. A study of 3,877 randomly selected patients found a significant link between three degenerative eye diseases—age-related macular degeneration, diabetic retinopathy and glaucoma—and Alzheimer’ disease. The results offer physicians […]
For researchers, making predictions about the outcome of an experiment requires close observation of available data. But in neurobiology, making accurate observations is hampered by the difficulty of measuring the individual cells. There is a workaround, however: modeling. Simulating the world based on experimental observation allows for accurate predictions, and with sophisticated programming, sophisticated models […]
Studying transthyretin amyloidoses-a group of progressive nerve and cardiac degenerative diseases caused by the buildup of misfolded transthyretin (TTR) proteins in the body-has long been hampered by the lack of animal models of the disease. Mice, for instance, don’t show the same symptoms as humans, even when misfolded TTR accumulates in their organs. Now, scientists […]
(HealthDay)—Spine surgeons are more likely to receive favorable online reviews for factors pertaining to outcomes and likeability/character and negative reviews based on ancillary staff interactions and office environment, according to a study published online July 2 in Spine. Chester J. Donnally III, M.D., from the University of Miami Hospital, and colleagues evaluated patient feedback and […]
TUESDAY, Aug. 7, 2018 — Photo-editing tools that make people look more perfect online than in real life may be a health threat, medical experts warn. The tidal wave of altered photos on social media is changing perceptions of beauty. And that can trigger a preoccupation with appearance that leads to risky efforts to hide […]
