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

Acute myocarditis, inflammation of the heart muscle typically triggered by a virus, occurred in about two out of every 1,000 people hospitalized with COVID-19, and was associated with more severe illness and complications in people with COVID-19, especially among people who also had pneumonia, according to new research published todayContinuar Leyendo

Mutant mice are providing scientists with a new neurobiological framework to understand the brain changes observed in distractible humans who carry a common gene variant whose frequency has been associated with Attention Deficit Hyperactivity Disorder (ADHD). The scientists demonstrate that mice that express the variant adopt an inattentive phenotype similarContinuar Leyendo

A new study has found that the Novaplex SARS-CoV-2 Variant I, II, and IV real-time PCR assays (from Seegene Technology) can reliably detect SARS-CoV-2 in patient samples and identify known variants of interest and concern. Results from the PCR assays were comparable to those from the «gold standard» spike geneContinuar Leyendo
