At weaning, 162 sows were assigned randomly to six treatments (27 in each treatment) according to a 2 X 3 factorial arrangement: two levels of supplementary folic acid (0 and 5 mg/kg of diet) and three treatments to stimulate ovulation (none, flushing and pregnant mare serum gonadotropin [PMSG] injection). All sows were mated twice within 7 d after weaning. Of the 162 animals originally selecte...

The aim of the present study was to investigate the endocrinology of periestrus period and the days after until estrus in ewes (n = 40) synchronized out of breeding season and diagnosing the related pregnancies after laparoscopic insemination comparing to different doses of PMSG that was used. Animals treated for 12 d with CIDR followed by administration with different doses (0, 450, 550, 650, ...

Functional and structural changes in the mammalian ovary are coordinately regulated by the pituitary glycoprotein hormones, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), leading to follicular development, ovulation and transformation of follicles into corpus lutea. To investigate protein profiles during these processes of the mouse ovarian cycle, we applied combined methods (...

This paper presents an analysis and simulation of a Wind Turbine Generator (WTG) driving a low speed Permanent Magnet Synchronous Generator (PMSG). The results of the tests are obtained by using the PSIM computer simulation program. The voltage source PWM inverter is used to interface the system with the electrical utility that is simulated in this paper as a resistive-inductive load.

This paper proposes a fast and accurate optimal sizing design of 1.5 MW Permanent Magnets Synchronous Generator (PMSG) for grid-connected wind application. A strategy inspired from the output space mapping technique is adopted. analytical model used detailed to determine parameters performances PMSG. Then, results are validated by precise finite element adjusted iteratively until coherence betw...

The hybrid renewable energy harvesting and grid integration system has been proposed validated in this work. uses a Wind Energy Conversion System (WECS) Solar Photo Voltaic (SPVECS). WECS Permanent Magnet Synchronous Generator (PMSG) driven by wind turbine. variable frequency voltage output of PMSG is rectified Diode Bridge Rectifier (DBR) stepped up Super Lift Luo Converter (SLLC 1), finally, ...

We have shown previously that mRNA for peroxisome proliferator-activated receptor gamma (PPARgamma) is expressed in granulosa cells and downregulated by the luteinizing hormone (LH) surge. The current studies were undertaken to test the hypothesis that LH stimulates a decrease in the expression of PPARgamma, as well as its activity, in granulosa cells. Ovaries were collected from immature rats ...

This research was conducted to study the follicular dynamics, hormonal, biochemical profile and fertility response in acyclic and norgestomet+PMSG treated acyclic buffaloes in summer. The study animals were divided into two groups: group I [control (n=8): no treatment] and II [treatment group (n=15)]. In group II, seven animals were used for follicular biochemical and hormonal profile and eight...

Glucocorticoids are known to have diverse effects on the uterus, generally believed to be mediated by the glucocorticoid receptor (GR). To date, two isoforms of the enzyme 11beta-hydroxysteroid dehydrogenase (11betaHSD) have been identified, namely 11betaHSD1 and 11betaHSD2, which interconvert active and inactive glucocorticoids and regulate local levels of hormones available to the GR in targe...
