Activation of SGK1/ENaC Signaling Pathway Improves the Level of Decidualization in Unexplained Recurrent Spontaneous Abortion.

Recurrent spontaneous abortion (RSA) is one of the most common complications during pregnancy and seriously affects women's physical and mental health. About 50% of RSA cases are of unknown etiology. Our previous study found that the decidual tissue of patients with unexplained recurrent spontaneous abortion (URSA) had low expression levels of serum and glucocorticoid-induced protein kinase (SGK) 1.

Repeated controlled ovarian stimulation-induced ovarian and uterine damage in mice through the PI3K/AKT signaling pathway.

The effects of repeated controlled ovarian stimulation (COS) on the female reproductive system are still controversial. This study investigated the effects of repeated COS on the ovaries and uterus of mice and its possible mechanism. Female ICR (Institute of Cancer Research) mice were subjected to the COS using pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (hCG) for 1, 3, 5, and 7 cycles.

Morroniside Protects Human Granulosa Cells against HO-Induced Oxidative Damage by Regulating the Nrf2 and MAPK Signaling Pathways.

Morroniside is the main ingredient of and has a variety of biological activities including antioxidative effects. Ovarian granulosa cells (GCs) are responsible for regulating the development and atresia of follicles, which are susceptible to oxidative stress. In this study, we determined whether morroniside can inhibit the oxidative stress of GCs induced by hydrogen peroxide (HO), leading to improved oocyte quality.

[Effect of GnRHa controlled ovarian hyperstimulation on mouse embryo implantation and its mechanism].

The purpose of the present study was to investigate the effects and underlying mechanism of gonadotropin-releasing hormone agonist (GnRHa) controlled ovarian hyperstimulation (COH) on embryo implantation in mice. Forty female Kunming mice aged 9 weeks were randomly divided into two groups (control and COH groups). The COH group received intraperitoneal (i.

Impacts of exposure to 900 MHz mobile phone radiation on liver function in rats.

Objective: To study the impacts of exposure to electromagnetic radiation (EMR) on liver function in rats.

Methods: Twenty adult male Sprague-Dawley rats were randomly divided into normal group and radiated group. The rats in normal group were not radiated, those in radiated group were exposed to EMR 4 h/ d for 18 consecutive days.

[Effect of Bushen Tiaojing Recipe containing serum on FSH/cAMP-PKA pathway in in vitro cultured human ovarian granular cells].

Objective: To explore the potential molecular mechanisms for Bushen Tiaojing Recipe (BTR) improving the endocrine function of ovarian granular cells by observing the effect of BTR containing serum on follicle stimulating hormone/cyclic adenosine monophosphate-protein kinase A (FSH/ cAMP-PKA) pathway in in vitro cultured human ovarian granular cells.

Methods: The primary ovarian granular cells collected from in vitro fertilization-embryo transfer patients were cultured for 24 h. The human and rat serum containing different concentrations of BTR (low, medium, high dose), and their normal serums were co-incubated with ovarian granular cells for 48 h respectively, and then they were divided into the low, medium, high dose BTR groups and the control group.

[Roles of potassium channel in effects of resveratrol on isolated myocardial contractility and heart rate research in guinea pig].

Objective: To study the effects of resvaratrol derivatives on spontaneous HR and CF of isolated guinea pig atrium.

Method: The dose-effect curve of resvaratrol was observed. The possible mechanism of potassium channels responsible for changes of CF and HR after administering with resvaratrol was measured.

[Effects of Semen Sojae Preparatum on lipid metabolism in ovariectomized rat].

Objective: To investigate the antiatherosclerotic effect of Semen Sojae Preparatum (SSP) and its mechanism.

Methods: 48 rats were randomly divided into sham operation group (sham), ovariectomized group (OVX) and three doses of OVX + SSP groups. SSP was given to OVX + SSP groups 2 weeks after ovariectomy.
