polycystic ovarian syndrome is a hetrogenous condition with a broad clinical and pathologic spectrum that may reflect the effects of diverse etiologic factors. polycystic ovarian syndrome is an abnormality in the maturation of the follicles which can result in abnormal composition of follicular fluid. by analysis and comparison of the biochemical composition of human follicular fluid in normal ...

A total number of 28 mature Barki ewes were divided into three groups according to the methods used for synchronization of estrous cycle with different drugs. Group I comprised 8 ewes received no drugs and served as control group. Group II included 10 ewes synchronized by 3 ml (15 mg) prostaglandin F2  injected i.m and repeated once after 9 days from the first injection.Group III comprised 10 ...

one of the basic tenets in recent international trade literature is about the effect of trade integration on business cycle synchronization (bcs) among trading countries. the objective of this paper is to explore the main determinants of business cycle synchronization, with emphasis on trade integration. to this end, we have specified two simultaneous regression equations which were estimated b...

In this paper, the synchronization of a new hyperchaotic complex system based on T-S fuzzy model is proposed. First, the considered hyperchaotic system is represented by T-S fuzzy model equivalently. Then, by using the parallel distributed compensation (PDC) method and by applying linear system theory and exact linearization (EL) technique, a fuzzy controller is designed to realize the synchron...

Given its rustic nature, its butchery quality and its trypanotolerance, the N’Dama breed represents a significant potential for developing African cattle breeding [6]. To date, its zootechnical performance and reproductive characteristics have been the subject of relatively little work. The use of selection programmes and artificial insemination are highly significant challenges for developing ...

Most fixed-time insemination protocols utilize an injection of GnRH at the beginning of the protocol to initiate a new follicular wave. However, the ability of GnRH to initiate a new follicular wave is dependent on the stage of the estrous cycle. We hypothesized that administering PGF(2α) 3 d before initiating a fixed-time AI protocol would improve synchrony of follicular waves and result in gr...

The aim of this study was to compare morphological and functional features of spontaneous and induced corpora lutea (CLs) in goats. Fourteen adult and cycling Anglo Nubian goats (Argentina) were randomly allocated to two groups: Group N (n=7) included goats with natural spontaneous oestrus and Group PG (n=7) included does in which oestrus was synchronized by the administration of two i.m. clopr...
