Ithaca, April 08, 2025.- Knocking out a single gene reprograms part of the large intestine to function like the nutrient-absorbing small intestine. In a preclinical study, Weill Cornell Medicine investigators showed that the technique reversed the malnutrition that results when most of the small intestine is removed. The successful demonstrationContinuar Leyendo
The increase of microbes resistant to antibiotics is a growing problem. These include, for example, Neisseria gonorrhoeae, a bacterium which causes gonorrhea. Researchers from the universities in Konstanz and Vienna discover a new class of antibiotic that selectively targets Neisseria gonorrhoeae. These substances trigger a self-destruction program, which also operatesContinuar Leyendo
Widely used by the food industry, emulsifiers – a type of food additive – are found in many daily foods (sliced bread, ice creams, crème fraîche, plant milks, etc.). Given their omnipresence in our diet, the health effects of their consumption have become a real public health issue. Benoit Chassaing,Continuar Leyendo
Vaccinations alone may not be enough to protect people with compromised immune systems from infection, even if the vaccine has generated the production of antibodies, new research from the University of Cambridge has shown. Cambrigde, Feb 14, 2025.- The findings, published today in Science Advances, suggest that such individuals willContinuar Leyendo
New Yok, Jn 24, 2025.- Some of the body’s cells stay put for life, while others are free to roam. To move, these migratory cells rely on filopodia—sensitive, finger-like protrusions that reach out from the cell membrane into the local environment. In a healthy cell, this can be a lifesaver:Continuar Leyendo
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
