Following an analysis of bacterial samples from infants with whooping cough, scientists from the National Reference Center (CNR) for Whooping Cough and other Bordetellosis have revealed that the most severe forms of the disease are associated with specific strains expressing a key vaccine antigen. This discovery suggests that the bacteriaContinuar Leyendo
Researchers have come up with a new way to identify more infectious variants of viruses or bacteria that start spreading in humans – including those causing flu, COVID, whooping cough and tuberculosis. Cambrigde, Jan 10, 2025.- The new approach uses samples from infected humans to allow real-time monitoring of pathogens circulatingContinuar Leyendo
Ithaca, Dec 18, 2024.- Prostate cancer hijacks the normal prostate’s growth regulation program to release the brakes and grow freely, according to Weill Cornell Medicine researchers. The discovery, published Dec. 13 in Nature Communications, paves the way for new diagnostic tests to guide treatment and could also help drug developersContinuar Leyendo
Cambridge scientists have developed a urine test for early detection of lung cancer. The test, the first of its kind, detects ‘zombie’ cells that could indicate the first signs of the disease. Cambrigde, Dec 13, 2024.- Researchers hope that early detection, through the simple urine test, could enable earlier treatmentContinuar Leyendo
An interdisciplinary study from the University of Bern reveals that gut bacteria play a crucial role in converting arsenobetaine into toxic arsenic compounds. Results show that arsenobetaine, commonly found in seafood and previously considered harmless, is partly transformed into toxic arsenic compounds by the action of gut bacteria in theContinuar Leyendo
Disruption of the microbial community favours pathogens in the gut In a groundbreaking new study, conducted within the framework of the FWF-funded Cluster of Excellence «Microbiomes drive Planetary Health», scientists from the University of Vienna, in collaboration with the University of Southampton, Aalborg University and Boston University, have revealed thatContinuar Leyendo
Myocarditis is driven by a different immune response than the anti-tumor one, suggesting that the serious complication could one day be managed without halting cancer therapy. By Leah Eisenstadt Cambrigde, Nov 12, 2024.- Some patients being treated with immune checkpoint inhibitors, a type of cancer immunotherapy, develop a dangerous formContinuar Leyendo
New York, September 26, 2024.- A new preclinical model using CRISPR, an advanced technology that allows scientists to cut and edit genes, has given Weill Cornell Medicine researchers and their colleagues a deeper insight into how prostate cancer spreads or metastasizes. In the study, published Sept. 23 in Cancer Discovery,Continuar Leyendo
Scientists have identified a gene which, when missing or impaired, can cause obesity, behavioural problems and, in mothers, postnatal depression. The discovery, reported on 2 July in Cell, may have wider implications for the treatment of postnatal depression, with a study in mice suggesting that oxytocin may alleviate symptoms. Cambrigde,Continuar Leyendo
Daniel Charlebois and an early-career international research team have been granted US$1.2 million from the Human Frontiers Science Program to seek to answer the question “How predictable is evolution?” Charlebois, along with Michael Manhart from Rutgers University and Meike Wortel from the University of Amsterdam, will examine the development ofContinuar Leyendo
