Scar-like cells that make up a sizable portion of malignant pancreatic tumors and shield these cancers from immune attack are derived from mesothelial cells that line tissues and organs, a new study led by UT Southwestern researchers suggests. The findings, published in Cancer Cell, could offer a new strategy toContinuar Leyendo
Elevated levels of an enzyme called PHGDH in the blood of older adults could be an early warning sign of Alzheimer’s disease, and a study led by the University of California San Diego provides new evidence to support this claim. In analyzing brain tissue, researchers observed a trend consistent withContinuar Leyendo
When you daydream, or ruminate on something bothersome, or ponder the past, or plan for the future, the part of your brain most engaged is the default mode network, or DMN, which includes part of the prefrontal cortex. Scientists have long hypothesized that changes to DMN dynamics play major rolesContinuar Leyendo
In a small but multi-institutional study, an artificial intelligence-based system improved providers’ assessments of whether patients with bladder cancer had complete response to chemotherapy before a radical cystectomy (bladder removal surgery). Ann Arbour, April 25, 2022.- Yet the researchers caution that AI isn’t a replacement for human expertise and thatContinuar Leyendo
Existing methods for detecting and diagnosing COVID-19 are either expensive and complex or inaccurate. Now, scientists from the Gwangju Institute of Science and Technology have developed a novel biosensing platform to detect and quantify viral particles using a simple optical microscope and antibody proteins. Their versatile approach, based on slowingContinuar Leyendo
One of the most important molecules in the brain doesn’t work quite the way scientists thought it did, according to new work by researchers at Columbia University Vagelos College of Physicians and Surgeons and Carnegie Mellon University. New York, April 21, 2022.- The results, published April 20 in Nature, mayContinuar Leyendo
Compared to the general population, people with severe mental illness, including schizophrenia, have higher levels of cardiovascular-related mortality, and that association has become stronger over recent decades, according to a new study publishing April 19 in PLOS Medicine by Amanda Lambert of the University of Birmingham, UK, and colleagues. Birmingham,Continuar Leyendo
Two strains of the bacterium causing tuberculosis have only minor genetic differences but attack the lungs in completely different fashion, according to Rutgers researchers. New Jersey, April 18, 2022.- The findings, published in the journal Nature Communications, could help break the cycle of rapid transmission of TB, the second-leading infectiousContinuar Leyendo
A new University of Gothenburg study has paved the way for the first drug treatment for sleep apnea. Compared to before receiving the treatment, breathing pauses decreased with on average more than 20 per hour for patients given the drug. Gothenburg, April 16, 2022.- The treatment that has been testedContinuar Leyendo
Inhibiting an important signaling pathway in brain-resident immune cells may calm brain inflammation and thereby slow the disease process in Alzheimer’s and some other neurodegenerative diseases, suggests a study by Weill Cornell Medicine investigators. The findings point to the possibility of new therapeutic strategies against neurodegenerative diseases, which are relativelyContinuar Leyendo
