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
París, March 23, 2022.- With extreme weather events threatening to be more frequent and more severe as the climate crisis takes grip, it’s never been more important to have fast and accurate forecasts. ESA and Eumetsat are working hard to ensure that there will be a constant stream of weatherContinuar Leyendo
A novel system to control protein aggregation in a model of Parkinson’s disease may answer longstanding questions about how the disease begins and spreads, according to a new study published March 9 in the open-access journal PLOS Biology by Abid Oueslati of Laval University, Quebec, Canada, and colleagues. Initial resultsContinuar Leyendo
Just one dose of a new nanoparticle-based COVID-19 vaccine was enough to produce an immune response in animals on track with vaccines currently in clinical use. And with minor changes, Northwestern University researchers hope the same vaccine platform could target other infectious diseases. Evanston, March 23, 2022.- In a newContinuar Leyendo
An international team with participation of the University of Bern provides new insights about how the inhabitants of the «oldest city in the world» in Çatalhöyük (Turkey) buried their dead. Their bones were partially painted, excavated several times and reburied. The findings provide insight into the burial rituals of aContinuar Leyendo
Alzheimer’s disease is the most common and best known of the tauopathies, a set of neurodegenerative brain diseases caused by toxic tangles of the protein tau. A study by researchers at Washington University School of Medicine in St. Louis has shown that targeting astrocytes — an inflammatory cell in theContinuar Leyendo
