In the present study, we evaluated the contributions of antral follicle development and antral granulosa cell-released factor(s) to the acquisition of a mature mouse oocyte plasma membrane organization and cortical granule distribution. This has been performed by comparing in-vitro matured oocytes derived from early antral follicles (here referred to as denuded oocytes) or from pre-ovulatory fo...

UNLABELLED Gastrokine-2 (GKN2) is a secretory peptide of human gastric surface mucous cells (SMCs). It forms disulfide-linked heterodimers with the trefoil factor family (TFF) peptide TFF1. Binding with TFF2 was also reported. Antral SMCs differ from those of the corpus by their TFF3 expression. The aim of this study was to localize GKN2 expression along the antral gland axis, to characterize t...

Title of Thesis: DETERMINATION OF THE DYNAMICS OF FELINE FOLLICLE METABOLISM Jennifer L. Colvin, Master of Science, 2013 Thesis Directed By: Associate Professor Brian J. Bequette, Department of Animal and Avian Sciences The metabolism of feline follicles has been largely overlooked in reproductive science. The primary objective of this study was to determine differences in metabolite profiles a...

In this survey the antral, pancreatic and, where present, the neoplastic gastrin cells, were studied in eight cases of the Zollinger-Ellison syndrome. The antral G cells alone were studied in one case of Z-E syndrome, seven cases of simple duodenal ulcer, and five cases of pernicious anaemia. The Z-E cases were divided into two numerically equal groups. The first group had ;short' histories, hi...

The aim of this study was to determine the effects and mechanism of synchronized gastric electrical stimulation (SGES) on gastric contractions and gastric emptying. The first experiment was designed to study the effects of SGES on antral contractions in four randomized sessions. Sessions 1 (control) and 2 (atropine) were performed in the fasting state, composed of three 30-min periods (baseline...

OBJECTIVE To investigate the relation between reproductive age and ultrasound (US)-based follicle counts and the reproducibility of follicle counts in regularly cycling women with proven fertility. DESIGN Prospective observational study. SETTING Tertiary fertility center. PATIENT(S) Healthy female volunteers with proven fertility, recruited by advertisement in local newspapers. INTERVEN...

BACKGROUND For the past decade, electric pulmonary vein isolation (PVI) has become a procedure implemented worldwide for the treatment of atrial fibrillation. Currently, 2 main approaches are used for PVI: ostial isolation of the PVs and wide antral PVI. The aims of this systematic review are to evaluate the relative merits of each technique with a pooled comparative analysis of efficacy and co...

CT scans of the maxillary antra in a group of 51 patients with nasopharyngeal carcinoma were compared with those of a control group of 50 patients. Inflammatory thickening of the antral mucosa was demonstrated in 39 of 42 patients with grade WHO (World Health Organization) 2 and 3 nasopharyngeal carcinoma. Biopsy of the antral mucosa in eight of these patients established inflammation and exclu...

Cyclotropium bromide, a new antimuscarinic agent, inhibits gastrointestinal motility in animals at lower doses than those required to inhibit gastric acid secretion and salivation. In man, cyclotropium bromide suppresses fasting and meal stimulated colonic motility. This study investigated the effects of single oral doses of 60 mg cyclotropium bromide, 60 mg hyoscine N-butylbromide and placebo ...
