Chemotherapy treatment is a mainstay of anticancer regimens, significantly contributing to the recent increase in childhood cancer survival rates. Conventional cancer therapy targets not only malignant but also healthy cells resulting in si...
Gestational nutrition 2: gene expression in sheep fetal ovaries exposed to gestational under nutrition [0.03%]
妊娠营养对绵羊胎儿卵巢基因表达的影响

Ovulation, which is induced by the ovulatory luteinizing hormone (LH) surge, is a dynamic process that results in a discharge of one or more fertilizable oocytes from the ovarian follicle into the ovarian cavity or into the abdominal cavity...
Endometrial mesenchymal stem/stromal cell modulation of T cell proliferation [0.03%]

The objective was to characterize effects of Escherichia coli LPS (given i.v.) on corpus luteum (CL) and embryonic viability in early pregnant cattle. Eight non-lactating German Holstein cows were given 0.5 µg/kg LPS on 35 ± 3 day (mean ...
Effects of androgen and oestrogen on IGF pathways controlling phallus growth [0.03%]
雄激素和雌激素对控制阴茎生长的胰岛素样生长因子途径的影响
Yu Chen,Hongshi Yu,Andrew J Pask et al.
Yu Chen et al.
The development of the mammalian phallus involves hormone-dependent mesenchymal-epithelial signalling mechanisms that contribute to urethral closure and regulation of phallus elongation and growth. In marsupials, most differentiation and gr...

Our understanding of G protein-coupled receptor (GPCR) signalling has significantly evolved over the past decade, whereby signalling not only occurs from the plasma membrane but continues, or is reactivated, following internalisation in to ...
Connexin hemichannels and cell death as measures of bovine COC vitrification success [0.03%]
胞质通道蛋白半通道和细胞死亡作为评价牛卵泡液中卵母细胞冷冻保存成功程度的指标
