Waqas Ahmad et al.
This study aimed to evaluate the ovulatory response to GnRH treatment based on the day of its administration in the first follicular wave of the estrous cycle in goats. We hypothesized that maximum ovulatory response with GnRH treatment is ...
Analyses of widely targeted metabolic profiling reveal enhanced energy metabolism in well-developed testicular tissue of Hu sheep [0.03%]

This review describes various aspects of the leptin resistance phenomenon and related physiological mechanisms that occur in pregnant sheep. Its main aim is to analyze the mechanisms that determine the occurrence of pregnancy-induced leptin...
Active immunization with a novel recombinant GnRH vaccine inhibits reproductive function in male goats [0.03%]
新型促性腺激素释放激素重组疫苗的主动免疫抑制公山羊的生殖功能
Moyan Di,Xinbao Gong,Yanyun Zhu et al.
Moyan Di et al.
Gonadotropin-releasing hormone (GnRH) vaccines have been widely used to effectively inhibit gonadal development and reproductive function. To improve the immunogenicity of GnRH, we developed and evaluated the effects of GnRH6-kisspeptin-CRM...
Poor maternal nutrition during gestation in sheep alters key hormonal systems involved in energy homeostasis and appetite in the offspring [0.03%]
母羊怀孕期间营养不良影响后代体内关键激素系统及摄食行为
Nicole M Tillquist,Kristen E Govoni,Steven A Zinn et al.
Nicole M Tillquist et al.
Disturbances in maternal nutrient availability through increased or decreased abundance of specific or total nutrients during pre-natal development can have negative impacts on offspring growth. These changes are likely mediated, at least i...
17β-estradiol inhibits lipopolysaccharide-induced inflammation and pyroptosis of Leydig cells of the domestic yak (Bos grunniens) via the SIRT1/Nox4/ROS pathway [0.03%]
雌二醇通过SIRT1/Nox4/ROS信号途径抑制牦牛(Leydig细胞的脂多糖诱导的炎症和焦亡反应
Junyuan Ma,Yanmei Yang,Lin He et al.
Junyuan Ma et al.
Estradiol (E2) secreted by Leydig cells (LCs) can accumulate in the testes due to constriction of the reproductive lumen. Estrogen is not only important for reproduction, but also protects against inflammation. In this study, the role of py...
Correlation of Anti-Müllerian hormone serum concentration measured in proestrus and estrus with the litter size as a fertility marker in bitches [0.03%]
抗穆勒管激素血清浓度与母狗生育力标志物及胎仔数量的相关性研究
Theresa Hornberger,Sven Reese,Klaus Perbandt et al.
Theresa Hornberger et al.
The use of the anti-Müllerian hormone (AMH) serum concentration as a fertility marker has been shown in cows, sheep and mares and has been indicated in one study in female dogs. The aim of this study was to investigate the connection betwe...
Evaluation of serum insulin-like growth factor 1 concentrations in non-diabetic cats with chronic kidney disease [0.03%]
