NewsStudy reveals insights into oral HPV incidence and risks in men across 3 countries
A new study has unveiled crucial information about the incidence and risk factors of oral human papillomavirus (HPV) infections among men in the United States, Mexico and Brazil - the virus is linked to up to 90% of all oropharyngeal cancer cases in men in the U.S.
-
NewsChemical trick activates antibiotic directly at the pathogen
Scientists have seen promising results after experimenting with a click-to-release approach that deploys a masked form of colistin to the site of an infection so that it is no longer as damaging to the kidneys while maintaining its high antibiotic efficacy.
