University of Calgary researchers probing the gut — «the inner tube of life» — have for the first time discovered specific factors in its workings that in the future may help improve treatment for patients facing gut damage or gastrointestinal disease. Calgary, Nov 15, 2021.- The findings from Snyder InstituteContinuar Leyendo
Imagine you are in a meadow picking flowers. You know that some flowers are safe, while others have a bee inside that will sting you. How would you react to this environment and, more importantly, how would your brain react? This is the scene in a virtual-reality environment used byContinuar Leyendo
Patients with mitral and tricuspid valve regurgitation, a condition sometimes called «leaky heart valves,» appeared to do better after two years if they had a tricuspid valve repair at the time of mitral valve surgery, according to a study supported by the National Heart, Lung, and Blood Institute (NHLBI), aContinuar Leyendo
A simple RNA molecule jumpstarts the immune system’s «first responders» to viral infection and can even eradicate the SARS-CoV-2 virus in mice with chronic cases of COVID-19, a new Yale School of Medicine study finds. New Haven, CT, Nov 11. 2021.- The molecule, known as SLR14, is a simple, easyContinuar Leyendo
Altered function of the red blood cells leads to vascular damage in type 2 diabetes. Results from a new study in cells from patients with type 2 diabetes and mice show that this effect is caused by low levels of an important molecule in the red blood cells. The studyContinuar Leyendo
Using data generated from patients and mice with genetic mutation for the disorder Usher syndrome, researchers from the University of Maryland School of Medicine (UMSOM), the National Institutes of Health’s National Eye Institute (NEI), and National Institute on Deafness and Other Communication Disorders (NIDCD), documented the natural history of visionContinuar Leyendo
Titin is a «titanically large» protein — the largest in the human body — which enables elastic movements of our muscles, including the heart. Mutations in the titin gene (TTN) that impair this function are the most frequent cause of a heart muscle disease known as dilated cardiomyopathy (DCM), whichContinuar Leyendo
Blocking a molecule that draws sensory nerves into musculoskeletal injuries prevents heterotopic ossification (HO), a process in which bone abnormally grows in soft tissue during healing, UT Southwestern researchers reported in a study. The findings, published in Nature Communications, suggest that drugs currently being tested in clinical trials to inhibitContinuar Leyendo
