Sperm movement has been described in several phyla of invertebrates. Yet, sperm motility has only been quantified using computer-aided sperm analysis (CASA-Mot) in externally fertilising species (broadcast spawners) of two phyla, molluscs a...
Combined oral contraceptives promote androgen receptor and oestrogen receptor alpha upregulation in the female prostate (Skene's paraurethral glands) of adult gerbils (Meriones unguiculatus) [0.03%]
复方口服避孕药促进成年仓鼠(Skene氏腺)雄激素受体和雌激素受体α的上调

Eliana G Pinto et al.
The aim of this study was to evaluate the effects of cyproterone acetate (CPA) and ethinyloestradiol (EE) alone or in combination on the female prostate of adult gerbils. Adult females were exposed for 21 days to daily oral doses of CPA (1m...
CASA-Mot technology: how results are affected by the frame rate and counting chamber [0.03%]
CASAS-Mot技术：帧率和计数室如何影响实验结果

Daznia Bompart et al.
For over 30 years, CASA-Mot technology has been used for kinematic analysis of sperm motility in different mammalian species, but insufficient attention has been paid to the technical limitations of commercial computer-aided sperm analysis ...
Expression of ENPP3 in human cyclic endometrium: a novel molecule involved in embryo implantation [0.03%]
人月经周期子宫内膜ENPP3的表达及其可能在胚胎植入中的作用研究
Qianqian Chen,Aijie Xin,Ronggui Qu et al.
Qianqian Chen et al.
Ectonucleotide pyrophosphatase-phosphodiesterase 3 (ENPP3), a protein detected in the human uterus, has been found to play an important role in the development and invasion of tumours. It was recently discovered that ENPP3 was upregulated d...
Astaxanthin counteracts the effects of heat shock on the maturation of bovine oocytes [0.03%]
虾青素对抗热休克对牛卵母细胞成熟的影响

J Ispada et al.
The cellular mechanisms induced by elevated temperature on oocytes are not fully understood. However, there is evidence that some of the deleterious effects of heat shock are mediated by a heat-induced increase in reactive oxygen species (R...
Dose and administration protocol for FSH used for ovarian stimulation affect gene expression in sheep cumulus-oocyte complexes [0.03%]
FSH的剂量和给药方案会影响山羊卵母细胞-颗粒细胞复合体的基因表达
Gláucia M Bragança,Ribrio Ivan T P Batista,Joanna Maria G Souza-Fabjan et al.
Gláucia M Bragança et al.
The present study evaluated the effect of four ovarian stimulation protocols on the follicular population and molecular status of cumulus-oocyte complexes (COCs). Twelve Santa Inês ewes (in a cross-over design) received 80 or 120mg FSH alo...
Current perspectives of CASA applications in diverse mammalian spermatozoa [0.03%]
用于不同哺乳动物精子的计算机辅助精液分析(CASA)技术的最新研究进展

Since the advent of computer-aided sperm analysis (CASA) some four decades ago, advances in computer technology and software algorithms have helped establish it as a research and diagnostic instrument for the analysis of spermatozoa. Despit...
Temporally differential protein expression of glycolytic and glycogenic enzymes during in vitro preimplantation bovine embryo development [0.03%]
体外受精牛胚胎植入前糖酵解和糖原生成酶的表达差异性研究

Proteomic analyses are useful for understanding the metabolic pathways governing embryo development. This study investigated the presence of enzymes involved in glycolysis and glycogenesis in in vitro-produced bovine embryos at five develop...
Antioxidant β-cryptoxanthin enhances porcine oocyte maturation and subsequent embryo development in vitro [0.03%]
抗氧化剂β-隐黄素可促进体外猪卵母细胞成熟和随后的胚胎发育
Yun-Gwi Park,Seung-Eun Lee,Yeo-Jin Son et al.
Yun-Gwi Park et al.
Oxidative stress is partly responsible for the poor quality of IVM oocytes. The present study investigated the effects of the antioxidant β-cryptoxanthin on the IVM of porcine oocytes and the in vitro development of the ensuing embryos. Oo...
