Gonadotropin-releasing hormone (GnRH) cells are the key regulators of reproductive function in all vertebrate organisms. The GnRH molecule is synthesized in a small number of neurons in rostral hypothalamic regions of the brain. In mammals, these neurons release the GnRH decapeptide into the portal capillary system leading to the anterior pituitary gland. There, GnRH causes the release of the gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn act upon the gonads to stimulate their maturation, and to cause synthesis of sex steroid hormones,...

Among the Old Order Mennonite and Amish communities of Lancaster County, Pennsylvania, the coming of the telephone posed a serious challenge to the longstanding traditions of work, worship, silence, and visiting. In 1907, Mennonites crafted a compromise in order to avoid a church split and grudgingly allowed telephones for lay people while prohibiting telephone ownership among the clergy. By 1909, the Amish had banned the telephone completely from their homes. Since then, the vigorous and sometimes painful debates about the meaning of the telephone reveal intense concerns about the...

Investigations of skeletal remains from key archaeological sites reveal new data and offer insights on prehistoric life and health in the
Southeast.

The shift from foraging to farming had important health consequences for prehistoric peoples, but variations in health existed

within communities that had made this transition. This new collection draws on the rich bioarchaeological record of the Southeastern United States
to explore variability in health and behavior within the age of agriculture. It offers new perspectives on human adaptation to various geographic...

There is scarcely a tract on the Colorado Plateau that does not have evidence of human occupation. Many of the richest remains have been found in the Mesa Verde Province, which covers southwestern Colorado and adjacent parts of New Mexico and Utah.

The archaeology of the north edge of the Southwest began in 1849 with the discovery of Chaco Canyon by the U.S. Army Corps of Topographical Engineers. By the end of the nineteenth century the form of archaeology known as pot hunting was well under way. In Troweling Through Time, Florence Lister tells the story of the archaeology of...
