Estimated timing of the first menstrual period and dietary and nutritional correlates of menarche among urban school‐going adolescents in four sub‐Saharan African sites

Maternal &Child Nutrition, EarlyView.
Abstract Characterizing the timing of menarche and the factors that are associated with it is important for understanding a population's reproductive health needs and long‐term health trajectories. We estimated the age at the menstrual onset among adolescent girls and the association between dietary and nutritional factors and menarche in four sub ...

Enteric neuropathy and the vagus nerve: Therapeutic implications

Neurogastroenterology &Motility, EarlyView.
Abstract Enteric neuropathies are characterized by abnormalities of gut innervation, which includes the enteric nervous system, inducing severe gut dysmotility among other dysfunctions. Most of the gastrointestinal tract is innervated by the vagus nerve, the efferent branches of which have close interconnections with the enteric nervous system and ...

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Functional grafts of the anterior pituitary gland

Proceedings of the Royal Society of London. Series B - Biological Sciences, 1951
A study has been made of pituitary grafts placed into hypophysectomized adult rats under the median eminence of the tuber cinereum, under the temporal lobe of the brain and into the hypophysial capsule. Good union was obtained in all three sites, the grafts becoming richly vascularized and remaining viable for long periods.

Acetylcholine receptors in the rat anterior pituitary gland.

Endocrinology, 1980
The muscarinic antagonist [3H]quinuclidinyl benzilate (QNB) was used to study muscarinic cholinergic binding sites in a crude membrane fraction prepared from the rat anterior pituitary gland. Specific [3H]QNB binding is saturable with a Kd of 16 pM and a

Bioassay of Sheep Anterior Pituitary Glands

Nature, 1959
A HIGHLY significant seasonal variation in frequency of twin ovulations in Merino ewes was observed by Radford1. In order to determine whether this was correlated with seasonal variation in pituitary gonadotrophin content the surviving ewes from Radford's experiment were later killed—16 in mid-summer (January–February 1958) and 11 in mid-winter (June ...

Role of estrogens in anterior pituitary gland remodeling during the estrous cycle.

Frontiers of Hormone Research, 2010
In this review, we analyze the action of estrogens leading to the remodeling of the anterior pituitary gland, especially during the estrous cycle. Proliferation and death of anterior pituitary cells and especially lactotropes is regulated by estrogens ...
