Regulation of ovarian oxytocin and prostaglandin F2[alpha] release in the ovine oestrous cycle
… prostaglandin F2a (PGF2a) release in the ovine oestrous cycle, their role in luteolysis and a possible mechanism by which the oxytocin secretory pathway is controlled in ovarian tissue.

Design, development and optimisation of veterinary intravaginal controlled release drug delivery systems
… intravaginal delivery of hormones to control the oestrous cycle of farmed animals, with particular emphasis on the delivery of progestagens to cattle and sheep. The introduction highlights the recent advances made by animal physiologists in their knowledge of the oestrous cycle in cattle and sheep …

Psychological and nutritional factors influencing the dynamics of gonadotrophin secretion in the female rat
… anoestrus was reversible. The latency of resumed oestrous cycling and associated body weight changes was investigated with rats on different rehabilitation regimens. A related objective was to determine whether a relationship existed between duration of malnutrition and recovery of the oestrous …

Studies on the influence of sex hormones on glucose tolerance and insulin secretion in the rat
… in female rats at different stages of the oestrous cycle, following ovariectomy and during advancing age indicate that enhanced sexual endocrine function is associated with an improvement of glucose tolerance and an elevation of plasma insulin levels.This interpretation is substantiated by …

Role of transient receptor potential channels in mammalian oviduct and uterine epithelia
… channels changes was measured throughout the oestrous cycle in bovine oviduct and uterine epithelial cells using Real-Time PCR, while immunohistochemistry, immunocytochemistry and western blotting were used to discover the localization of TRPC channels in oviduct/uterine epithelium and changes …

Angiogenesis and angioregression gene expression analyses in swine corpus luteum
… with the functional CL stage throughout the oestrous cycle and at pregnancy. The results demonstrated differential patterns of expression of those molecules in correspondence to the different phases of the oestrous cycle. Immediately after ovulation, VEGF mRNA/protein levels and MMP-9 …

The efficiency of ultrasonorgraphy in monitoring ovarian structures and foetal development in goats, sheep and cattle as verified through laparoscopy and laparotomy
… used on days 3 and 10 of the goats and sheep oestrous cycle. The follicles were grouped into three categories according to their diameter as 3 - 4.9 mm, 5 - 7.9 mm and ≥ 8 mm, whereas the follicles of cattle were grouped as 3 - 4.9 mm, 5 - 9.9 mm and ≥ 10 mm. Early pregnancy diagnosis …

The Influence of Ovarian Sex Steroids on Insulin Receptor Status in Mice
… compared to mice at dioestrus, two stages of the oestrous cycle which represent high and low plasma concentrations of the ovarian sex steroids respectively. Unchanged insulin binding data suggested that this increase in insulin action was mediated at the post-receptor level in both skeletal muscle …

Investigating the role of PABPC5 in mouse physiology
… of knock-out mice exhibited an irregular oestrous cycle. No changes in levels of LH, FSH, and progesterone were observed. At 24 weeks, female Pabp5 knock-out mice also exhibited no changes in body and ovary weight. No gross morphological differences were noted, nor was general follicular …

Thermoregulation, hibernation and reproduction in the South African hedgehog Erinaceus frontalis A. Smith
… during September and October. Aspects of the oestrous cycle of the female hedgehog were determined by progesterone levels in urine. These levels showed that the three females studied, had three or more oestrous cycles during the breeding season.

Novel insights into early life stress-induced dysfunction of the gut-brain axis
… germ-free mice. Here, we observed that the oestrous cycle modulated the visceral pain response in a microbiota-dependent manner and ovariectomy resulted in visceral hypersensitivity in conventional animals only. We then assessed alterations in the immune profiles of pre-adolescent rats and …

Assistierte Reproduktion beim Pferd
… ovulating mares. Synchronisation of the oestrous cycle of the donor and recipient mare before transfer is of major importance. In synchronized recipients, ovulation should occur one day before to three days after the donor mare's ovulation. Ovariectomized, hormone-treated mares have also …

Evaluation of the oral delivery of goserelin with Pheroid® technology
… or lack thereof of the 4-stage oetrous cycle. The vaginal cytology revealed disruption in the oestrous cycle in groups 1 and 2. Thus it can be concluded that the oral administration of goserelin in pro-Pheroid resulted in sufficient uptake to cause the hormonal effects. The …

A neural and behavioural investigation of aberrant feeding in animal models of autism spectrum disorder
… behaviour across different stages of the oestrous cycle. Female Cntnap2-/- mice exhibited overconsumption of sucrose, which remained consistent across all oestrous phases. This study suggests that palatability-driven overconsumption of sugar occurs in female Cntnap2-/- mice and does not …
