The interstitial cells of Cajal (ICC) are widely believed to be neuroeffector cells of smooth muscle activity in all tubular organs, including the oviduct. The avian oviduct involves the secretion, sheathing, and transportation of a large-sized egg, but there is no information available on ICC in this special organ. We have demonstrated the presence of ICC in different segments throughout the o...

BACKGROUND Mating changes the mechanism by which E2 regulates oviductal egg transport, from a non-genomic to a genomic mode. Previously, we found that E2 increased the expression of several genes in the oviduct of mated rats, but not in unmated rats. Among the transcripts that increased its level by E2 only in mated rats was the one coding for an s100 calcium binding protein G (s100 g) whose fu...

The present study was conducted to identify the histological effects of aqueous extract saffron flower on ovaries and oviducts adult female mouse at doses 15, 30 60 mg/kg body weight (b.w.).for periods 7,15 days, respectively once a day. Behavioral changes were include abnormal hyperactivity, irritability followed by introversion reduction motor activity, as well loss appetite for food drinking...

Drosophila have emerged as a model system to study mammalian neurodegenerative diseases. In the present study we have generated Drosophila transgenic for ovine PrP (prion protein) to begin to establish an invertebrate model of ovine prion disease. We generated Drosophila transgenic for polymorphic variants of ovine PrP by PhiC31 site-specific germ-line transformation under expression control by...

The oviduct of the laying hen is an organ histologically differentiated into four areas, each with a unique function in the biosynthesis of the egg (2). It contains high concentrations of a number of unusual nucleotides, including uridine diphosphoacetylgalactosamine and uridine diphosphoacetylgalactosamine-(4?)sulfate (3). More recently, it has been observed that uridine diphosphoacetylgalacto...

The oviduct plays a vital role in ensuring successful fertilization and normal early embryonic development. The male inseminates many thousands or even millions of sperm, but this alone does not ensure that fertilization will be successful. The female tract, particularly the oviduct, provides filters that select for normal vigorously motile sperm. In conjunction with molecules in the seminal pl...

The aim of the study was to analyze the application value of three-dimensional hysterosalpingo-contrast sonography (3D-HyCoSy) in the diagnosis of oviduct obstruction. Fifty-two patients with infertility and oviduct obstruction were continuously selected and treated with 3D-HyCoSy and CLP (CLP). It was found that according to CLP diagnosis, 40 oviducts were obstructed, 30 were partially obstruc...

This study examined the effect of the presence of single or multiple embryos on the transcriptome of the bovine oviduct. In experiment 1, cyclic (nonbred, n = 6) and pregnant (artificially inseminated, n = 11) heifers were slaughtered on Day 3 after estrus, and the ampulla and isthmic regions of the oviduct ipsilateral to the corpus luteum were separately flushed. Oviductal epithelial cells fro...

Chlamydia trachomatis is the most common bacterial sexually transmitted disease in the United States and a major cause of female infertility due to infection-induced Fallopian tube scarring. Epithelial cells are likely central to host defense and pathophysiology as they are the principal cell type productively infected by C. trachomatis. We generated cloned murine oviduct epithelial cell lines ...
