Normal pubertal development in humans involves two distinct processes: maturation of adrenal androgen secretion (adrenarche) and activation of the hypothalamic–pituitary–gonadal axis (gonadarche). One factor thought to contribute to the adrenarche in man is increased adrenal 17-hydroxylase (CYP17) activity.

Effects of Circulating and Local Uteroplacental Angiotensin II in Rat Pregnancy. [PDF]
The renin-angiotensin (Ang) system is important during placental development. Dysregulation of the renin-Ang system is important in preeclampsia (PE). Female rats transgenic for the human angiotensinogen gene crossed with males transgenic for the human ...

Megakaryocytopoiesis in the Rat [PDF]
Abstract Labeling of rat megakaryocytes was observed after a single intravenous injection of tritiated thymidine, and the following conclusions were made. 1. Morphologic appearance of megakaryocytes corresponded to their stage of maturation. 2. Only the youngest recognizable megakaryocytes (stage I) appeared

The brattleboro rat displays a natural deficit in social discrimination that is restored by clozapine and a neurotensin analog. [PDF]
Cognitive deficits in schizophrenia are a major source of dysfunction for which more effective treatments are needed. The vasopressin-deficient Brattleboro (BRAT) rat has been shown to have several natural schizophrenia-like deficits, including ...

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population
This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...

Improved timed-mating, non-invasive method using fewer unproven female rats with pregnancy validation via early body mass increases [PDF]
For studies requiring accurate conception-timing, reliable, efficient methods of detecting oestrus reduce time and costs, whilst improving welfare. Standard methods use vaginal cytology to stage cycle, and breeders are paired–up using approximately five ...

AbstractRats are often despised. In what way does such aversion affect moral deliberation, and if so, how should we accommodate any distorting effects on our normative judgements? These questions are explored in this chapter with regard to recent proposals in (1) the ethics of pest management and (2) animal political theory.
