Nearly half of genes that code for proteins showed a circadian rhythm in at least one mouse organ. In most organs, such as the liver, the researchers noted that the expression (activity) of many genes peaked during “rush hours” before dawn and dusk.

The papers report on a review of 14 diverse studies involving 1,443 women. All of the studies looked at the accuracy of using a self-administered urine test designed to detect HPV DNA. HPV is a group of viruses, some of which can cause cervical cancer in women. The advantage of such a self-administered urine test is it may improve uptake of cervical screening.…more
