by Brendan McMullan, Philip Britton, The Conversation Credit: Shutterstock The Delta variant is more infectious and is leading to more COVID-19 cases in children than previous strains. Many parents are wondering whether Delta is making kids sicker, and how to care for their children if they get COVID. It can be a nerve-racking time for parents, but there...

by Bob Yirka , Medical Xpress Three-dimensional schematic of the CNN–nanoparticle-enabled smartphone for virus detection. The detection process comprises three main steps. (A) Virus capture and labeling using Pt-nanoprobes. The samples are loaded into microchips modified with mAbs against the virus envelope protein and incubated to allow the capture of target virus for 20 min....
UNIVERSITY OF MISSOURI-COLUMBIA Viruses such as HIV, hepatitis B and hepatitis C evade or disrupt the immune system to create persistent infections. These viruses remain a serious health threat, but researchers from the University of Missouri School of Medicine have discovered how an enzyme that regulates several cellular processes might be a key target to preventing viruses...
by Georgia State University Administration of IL-22 approximately doubled the rate at which rotavirus-infected cells of the intestinal wall migrated toward villus tips (second to left). Administration of IL-18 (second to right) and a combination of IL-18 and IL-22 (right) also increased the migration rate of these cells to a lesser extent. Credit: Zhang et al.,...
by Delthia Ricks , Medical Xpress The immune system mounts robust responses to infections, vaccines and cancer, but only now have scientists fully begun to unravel how non-circulating populations of T cells that reside in the body’s “mucosal barrier tissues” keeps threats at bay. While an academic focus on non-circulating T cellsin mucosal tissues may...
Antibiotics are lifesaving drugs, but overuse is leading to one of the world’s most pressing health threats: antibiotic resistance. Researchers at the University of Rochester Medical Center are developing a tool to help physicians prescribe antibiotics to patients who really need them, and avoid giving them to individuals who don’t. Scientists from the University’s National...
