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 / 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.
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 / 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 / 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 / How the Epstein-Barr virus hooks onto DNA to reorganize genome and drive nasopharyngeal cancer spread
Researchers from the University of Hong Kong have discovered that the Epstein-Barr virus (EBV), a common human virus closely linked to nasopharyngeal carcinoma (NPC), can change the 3D structure of the human genome inside ...
Medical Xpress / Intestinal surface cells pull rather than push to remove weak neighbors, research reveals
Cells on the inner surface of the intestine are replaced every few days. But, how does this work? It was always assumed that cells leave the intestinal surface because excess cells are pushed out.
Medical Xpress / Squeezing through tiny blood vessels may trigger melanoma cells to spread
Nine of the 10 most common cancer deaths in Australia are caused by solid tumors, but in most cases it's the cancer's spread to other parts of the body—known as metastasis—that proves fatal.
Medical Xpress / Invisible influence: How cultural cognitive biases influence visuomotor adaptations
The process of improving the synchronization between visual perception and motor skills is called visuomotor learning. It entails adaptation of movements based on visual information. This kind of training can help with skill ...
Medical Xpress / Acid-resistant artificial mucus improves gastric wound healing in animals
Hydrogels—materials like gelatin that can absorb and hold water—can aid wound healing and enable slow-release drug delivery, but they usually break down in acidic environments like the stomach.
Medical Xpress / Adrenaline receptor helps set daily rhythm for T cell infection response, study finds
A newly discovered "timekeeper" for fighting infections dramatically shapes the body's immune defenses, offering insight as to why antiviral T cell response varies throughout the day, according to UT Southwestern Medical ...
Medical Xpress / Marmosets and modeling provide new paradigm for understanding social cognition
We consider humans to be at the apex of social cognition. But we're not the only animals that closely interact with each other. Marmosets, for example, are highly social creatures. In the wild, they choose to work together, ...
