One night of sleep loss can alter clock genes in your tissues Genes that control the biological clocks in cells throughout the body are altered after losing a single night of sleep, researchers report. For the study the researchers studied 15 healthy normal-weight men who on two separate occasions came to the lab for almost 2-night long stays. During the second night the participants slept as usual (over 8 hours) in one of the two sessions, while they were kept awake in the other of these sessions, but in random order.
Fluorescent material reveals how cells grow Fiber from a semiconducting polymer, developed for solar cells, is an excellent support material for the growth of new human tissue. Researchers have shown that the fiber glows, which makes it possible to follow the growth of the cells inside living tissue.
Healthcare providers a major contributor to problem of antibiotic overuse Differences in the routines of individual providers drives variation in antibiotic prescribing, more than differences in patient characteristics, standards of practice at different hospitals, or clinical settings (emergency department, primary care, urgent care). The report is an important step toward understanding the problem of antibiotic overuse, a major public health concern given the rise in antibiotic-resistant 'superbugs.'
Using low-dose irradiation, researchers can now edit human genes For the first time, researchers have employed a gene-editing technique involving low-dose irradiation to repair patient cells. This method is 10 times more effective than techniques currently in use.
Coping by avoidance in making decisions for relatives in ICU may lead to PTSD Family members who make major medical decisions for relatives in an intensive care unit may suffer posttraumatic stress disorder if they cope by avoiding the situation..
