Cerebral oedema is a dangerous complication in many brain-related conditions such as strokes. Researchers have now developed a new measurement method that enables a better understanding of the cellular causes of cerebral oedema. According to a new study, the TRPV4 ion channel in particular plays an important role. Our brain is well-protected by the bone…

New research suggests that chemotherapy could better target brain tumors in mouse models when it was administered at night instead of during the day. That’s because the blood-brain barrier was more likely to allow the chemotherapy to pass through it at night. The findings highlight the importance of this area of research in humans, and…

Obesity risk factors of family background are associated with changes in the brain function, finds a new study. The results show that the function of neural networks regulating satiety and appetite is altered already before a person develops obesity. Obesity is a globally increasing health problem, and new interventions to prevent and treat obesity are…

Electrical engineers report that the tiny beads of sweat, which appear in patients experiencing PTSD or other neuropsychiatric disorders can be measured and used to design and more responsive brain stimulator for therapy. «Sweat primarily helps maintain body temperature; however, tiny bursts of sweat are also released in response to psychologically arousing stimuli. Tracking the…

Researchers attempted to unravel such mechanisms by adopting non-invasive diffusion magnetic resonance imaging (MRI) to study the brains of SLE patients, particularly the white matter, coupled with computerized neuropsychological assessment. White matter lies beneath the grey matter cortex in the human brain and comprises millions of bundles of nerve fibers that transmit signals to different…

Our visual processing is facilitated by spaces near the hand in a process known as hand proximity attention. Using a visual phenomenon called the flash-lag effect, researchers showed that proprioceptive information of a hand contributed to hand proximity attention. Project lead Satoshi Shioiri explained that «since top-down attention was fixed at a location, we concluded…

Flavor, safety and family attitude toward vaping are among the greatest factors influencing teenage perception of e-cigarettes, new research finds. Published in the September-October issue of the Journal of Pediatric Nursing, the study is one of a few to examine the perception adolescents have of e-cigarettes and where these youth receive information about the products.…

Researchers and their partners have discovered a slimy strategy used by bacteria to defeat antibiotics and other drugs used to combat infections afflicting people with cystic fibrosis. Cystic fibrosis is a life-threatening disease that causes persistent lung infections and limits a person’s ability to breathe over time. A common strain of bacteria, Pseudomonas aeruginosa, often…

A mouse model of glioblastoma, an aggressive type of cancer that can occur in the brain, suggests that this recalcitrant cancer originates from a pool of stem cells that can be a significant distance away from the resulting tumors. The findings of a new study suggest new ways to fight this deadly disease. Despite decades…

One in six women experience long-term post-traumatic stress following miscarriage or ectopic pregnancy. This is the finding of the largest ever study into the psychological impact of early-stage pregnancy loss, from scientists at Imperial College London and KU Leuven in Belgium. The research, published in the journal American Journal of Obstetrics and Gynaecology, studied over…
