Results were released this week on a new treatment with the potential to improve the outcomes for patients with hereditary BRCA mutations and high-risk, early-stage breast cancer. These results represent the first time a drug that blocks cancer cells from repairing their DNA (called a PARP inhibitor) has been shownContinuar Leyendo

It’s long been known that people living with HIV experience a loss of white matter in their brains. As opposed to «gray matter,» which is composed of the cell bodies of neurons, white matter is made up of a fatty substance called myelin that coats neurons, offering protection and helpingContinuar Leyendo

Researchers have discovered a gene, OTUD7A, that impacts the development of Ewing sarcoma, a bone cancer that occurs mainly in children. They have also identified a compound that shows potential to block OTUD7A protein activity. The finding, by scientists at the University of North Carolina and the Lineberger Comprehensive CancerContinuar Leyendo

Crohn’s disease, a type of inflammatory bowel disease (IBD) that causes inflammation (pain and swelling) in the gastrointestinal tract, can cause daily health problems, frequent hospitalizations and surgery when not adequately controlled. While there is no cure for Crohn’s disease, there are treatments that can help patients live a symptom-freeContinuar Leyendo

Seeing, hearing, thinking, daydreaming — doing anything at all, in fact — activates neurons in the brain. But for people predisposed to developing brain tumors, the ordinary buzzing of their brains could be a problem. A study by researchers at Washington University School of Medicine in St. Louis and StanfordContinuar Leyendo

Amsterdam, May 26, 2021.- Alzheimer’s disease is the main cause of dementia and current therapeutic strategies cannot prevent, slow down or cure the pathology. The disease is characterized by memory loss, caused by the degeneration and death of neuronal cells in several regions of the brain, including the hippocampus, whichContinuar Leyendo

Within the next decade, the novel coronavirus responsible for COVID-19 could become little more than a nuisance, causing no more than common cold-like coughs and sniffles. That possible future is predicted by mathematical models that incorporate lessons learned from the current pandemic on how our body’s immunity changes over time.Continuar Leyendo

Scientists at UCL have identified a new immunotherapy to combat the hepatitis B virus (HBV), the most common cause of liver cancer in the world. London, May 17, 2021.- Each year, globally, chronic HBV causes an estimated 880,000 deaths from liver cirrhosis and hepatocellular carcinoma/liver cancer (HCC). The pioneering studyContinuar Leyendo

B cells are the immune cells responsible for creating antibodies, and most B cells, known as B2 cells, produce antibodies in response to a pathogen or a vaccine, providing defense and immunity against infections. But a small subset of long-lived B cells, known as B1 cells, are quite different fromContinuar Leyendo

Curiosity is the motivational drive for exploring and investigating the unknown and making new discoveries. It is as essential and intrinsic for survival as hunger. Until recently, the brain mechanisms underlying curiosity and novelty seeking behavior were unclear. However, researchers from the Netherlands Institute for Neuroscience have now discovered aContinuar Leyendo
