The current study designed to evaluate the role of pluripotent stem cells (iPSc) on experimentally-induced ovarian ablation (OA) by evaluating hematological parameters, FSH and E2 changes, molecular histopathological examination. 50 female rats were divided into five groups with 10 in each group. Group (1): control (2): injected Doxorubicin (DOX) (3 mg/kg) Cyclophosphamide (CYP) (50mg/kg) disso...

Simple control of a stand-alone variable speed wind turbine with permanent magnet synchronous generator (PMSG) is presented in this paper. PMSG fed different types loads by means converter where switched mode rectifier connected to the PMSG, boost DC-DC converter, and voltage source inverter (VSI). The operated at measured it tested estimated which based on power calculation power, generating e...

This paper presents a Variable Structure Sliding Mode Control (VS-SMC) scheme and Direct Torque Control (DTC) for Wind Farm (WF) based on the Permanent Magnet Synchronous Generator (PMSG). The WF consists of a 3 PMSGs which are connected to a common dc bus system with rectifier. The dc-bus is connected to the electrical network using only one inverter system, a grid-side filter as well as the t...

Propylthiouracil (PTU)-induced hypothroidism has been shown to produce a significant increase in the uptake of radiophosphorus (““P) by the testes of young chicks. Continued investigation of this effect demonstrated that thyroidectomy of young birds resulted in elevations in testis 32P uptake comparable to those observed following the administration of PTU. It would thus appear that the increas...

A new application of the three-phase buck-resonant converter is presented in this paper. It is shown that the analyzed converter is suitable to operate as the rectifier stage in low power wind energy conversion systems (WECS) based on permanent magnet synchronous generators (PMSG) with variable wind speed. As main features, it presents a single controlled switch, simple implementation and contr...

This paper proposes an electric powertrain architecture for future hybrid aircrafts which structure is only composed of permanent magnet synchronous machines both generators (PMSG) and motors (PMSM). The direct connection through AC bus a PMSG with one or several PMSMs involves the suppression power electronics usually embedded in powertrains. idea clearly to simplify significantly reduce weigh...

Prepuberal gilts were injected with PMSG to determine whether expression of a bovine growth hormone (bGH) transgene inhibited preovulatory maturation of ovarian follicles. Seven transgenic (TG) gilts of line 3706, which expresses a mouse metallothionein-bGH transgene, and eight nontransgenic, control (C) gilts (128 to 147 d old) were injected with PMSG, 12.5 IU/kg BW, 72 h before necropsy. Surf...

Rat oocytes can be produced artificially by superovulation. Because some strains show low sensitivity to superovulation treatment, in vitro maturation is an alternative method to produce numerous matured oocytes. Furthermore, establishment of an in vitro maturation system with simple culture conditions is cost effective and leads to easy handling of oocytes. This study examined developmental ab...

BACKGROUND The aim of this study was to characterize the roles of nitric oxide (NO) on the rat ovarian blood flow (OBF) during the preovulatory period. METHODS AND RESULTS Immature Sprague-Dawley rats were primed with pregnant mares' serum gonadotrophin (PMSG, 15 IU) and given hCG (15 IU) 48 h later. The ovary was exposed 48-56 h after PMSG, a laser Doppler probe was attached to the ovarian s...
