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
A significant amount of genetic risk for asthma is likely mediated through altered gene expression within the airway epithelium. That is the conclusion of a National Jewish Health-led study to identify genetic variants that cause asthma by altering the function of airway cells. The team’s paper published March 28, 2022,Continuar Leyendo
University of Notre Dame researchers have discovered another way tumor cells transfer genetic material to other cells in their microenvironment, causing cancer to spread. Notre Dame, In, March 28, 2022.- In their latest study, published in Cell Reports, Crislyn D’Souza-Schorey, the Morris Pollard Professor in the Department of Biological Sciences,Continuar Leyendo
Vagus nerve stimulation (VNS), sometimes referred to as a «pacemaker for the brain,» involves a stimulator device that is implanted under the skin in the chest, with a wire that is wound around the vagus nerve in the neck. It helps prevent seizures by sending regular, mild electrical pulses toContinuar Leyendo
A University of Iowa neuroscience research team has identified a fundamental biochemical mechanism underlying memory storage and has linked this mechanism to cognitive deficits in mouse models of Alzheimer’s Disease and Related Dementias. Iowa City, March 24, 2022.- While working to understand how memories are formed and stored in theContinuar Leyendo
