Prenatal Stress Keeps Infants, Toddlers up at Night, Study Says

...d sleep doesnt come easily to kids whose signaling systems may not be properly calibrated, OConnor said. However, more research is needed to monitor this signaling pathway more closely, watching for biological hints as to why sleep and behavioral disturbances so often crop up together. In the meantime, pr...

Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily

...lls, so it will be exciting to look at other viral systems with our experimental method,” she said. Many different viruses could enter cells by efficiently lowering the energy required to penetrate a cell’s outer membrane, according to Tristram-Nagle and her collaborator, John Nagle, professor of physics an...

Identified main genetic variants involved in response to HIV

...ciated to genes encoding HLA-B and HLA-C molecular systems would explain up to 15% of viral load variation among patients, whereas the third genetic variation would explain 5.8% of these differences. Further study of other genetic regions involved in this process is needed. Nevertheless, HLA-B variation pres...

In mice, drug protects against diabetes and atherosclerosis

...he report describes tests of the inhibitor on cell systems in culture and in live mice. In one experiment, mice genetically engineered to be highly susceptible to atherosclerosis were fed high-fat diets and assigned to receive the drug or an inert substance. One set of mice was put on a high-fat "western" di...
