The molecular basis of ungulate and non-rodent conceptus elongation and gastrulation
remains poorly understood; however, use of state-of-the-art genomic technologies is …

The environment contributes to production diseases that in turn badly affect cow
performance, fertility and culling. Oestrus intensity is lower in lame cows, and in all cows …

Opioid peptides are well‐known modulators of the central control of reproduction. Among
them, dynorphin coexpressed in kisspeptin (KP) neurons of the arcuate nucleus (ARC) has …

Balance between metabolic and reproductive processes is important for survival, particularly
in mammals that gestate their young. How the nervous system coordinates this balance is an …

Elevated and sustained estradiol concentrations cause a gonadotropin-releasing hormone
(GnRH) and luteinizing hormone (LH) surge that is necessary for ovulation. In sheep …

Recent evidence has implicated neurokinin B (NKB) signaling in the retrochiasmatic area
(RCh) of the ewe in the LH surge. To test this hypothesis, we first lesioned NK3R neurons in …

Two modes of gonadotropin-releasing hormone (GnRH) and luteinizing hormone (LH)
secretion are necessary for female fertility: surge and episodic secretion. However, the …

In the ewe, steroid hormones act on the hypothalamic arcuate nucleus (ARC) to initiate the
GnRH/LH surge. Within the ARC, steroid signal transduction may be mediated by estrogen …

In studying the efficiency of a variety of methods for estrus detection in a large dairy herd, we
suspected a definite sequence of estrus signs. Consequently, we observed a subset of …

旨在初步探索生长抑素(somatotropin release inhibitory factor, SRIF) 在绵羊子宫内膜上皮细胞
中的作用. 本研究中, 绵羊子宫组织样品来自新疆石河子市牛羊定点屠宰场 …
