Folia Parasitologica (57)3 2010
Abstract
An ultrastructural study of the ovarian follicles and their associated oviducts of the cestode Gyrocotyle urna Grube et Wagener, 1852, a parasite from the spiral valve of the rabbit fish, Chimaera monstrosa L., was undertaken. Each follicle gives rise to follicular oviduct, which opens into one of t...

Endocrinology (151)7 2010
Abstract
Cilium and flagellum beating are important in reproduction and defects in their motion are associated with ectopic pregnancy and infertility. Adrenomedullin (ADM) is a polypeptide present in the reproductive system. This report demonstrates a novel action of ADM in enhancing the flagellar/ciliary be...

Abstract
We hypothesized that during host invasion, the replicating IBV population further changes as it confronts the distinct environments of different tissues, leading to selection of the most fit population. We inoculated 15-day-old chickens with 10(4) 50% embryo infective doses of an Ark-type IBV commer...

Localization of phosphorylated SMAD proteins in granulosa cells, oocytes and oviduct of female mice.
Abstract
We also observed substantial staining for pSMADs in intact fully-grown oocytes from antral follicles. In granulosa cells, immunostaining for both pSMAD2/3 and pSMAD1/5/9 was apparent in preantral granulosa cells from primordial to secondary follicles. In antral follicles, immunostaining for pSMADs b...

Based on the expression levels in uninfected COEC, AvBDs can be loosely grouped into three categories with AvBD4-5 and AvBD9-12 being constitutively expressed at high levels; AvBD1, AvBD3, and AvBD13-14 at moderate levels; and AvBD2 and AvBD6-8 at minimal levels. Infection with the wild type SE stra...

Abstract
Sperm hyperactivation is characterised by high-amplitude, asymmetrical flagellar bending and is required to penetrate the oocyte zona pellucida. It was proposed that hyperactivation also enables spermatozoa to reach the oocyte by assisting escape from the oviductal sperm reservoir. To test this hypo...

Abstract
A unique property of the avian oviduct is to store sperm for a prolonged period. The sperm storage tubules (SST) are located in the utero-vaginal junction of the oviduct, where sperm can be stored and survived for a few weeks after insemination or natural mating. The immune system in the oviduct is...
