Brief Summary: This study marks significant progress in understanding ancient genomes, particularly in deciphering chromosomal sex, aneuploidies, and their broader historical and societal implications. By extracting and analyzing DNA from ancient remains, researchers have uncovered new insights into disorders of sex development (DSDs) that were previously inaccessible. These authors pioneered a computational method to identify sex chromosomal aneuploidies. This approach indepe...

Brief Summary:This study shows that brain-derived cellular communication network factor 3 (CCN3) is a potent osteoanabolic hormone to enhance bone formation in lactating female mice. CCN3 is produced by KISS1 neurons in the brain, and operates through a unique signaling pathway that interacts with bone-forming osteoblasts leading to increased bone formation.During lactation, the increased calcium demand for milk production leads to considerable bone loss...

Brief Summary: This paper reviewed the toxicity of radiation therapy (RT) on ovarian, uterine and vaginal tissue in childhood cancer survivors (CCSs), using data published from 1970 to 2017. Overall, 11 studies reported data on ovarian damage, 8 on uterine volume related to treatment, and 3 on vaginal effects. Most studies did not report accurate dosimetric data and dose-volume relationships, and the confounder role of chemotherapy was not considered. In general, published dat...
