Background—The eVect of histamine H2 receptor antagonists on gastric emptying is controversial. Aims—To determine the eVects of ranitidine, famotidine, and omeprazole on gastric motility and emptying. Patients and methods—Fifteen normal subjects underwent simultaneous antroduodenal manometry, electrogastrography (EGG), and gastric emptying with dynamic antral scintigraphy (DAS). After 30 minute...

Purpose To identify which methods used in the assessment of the ovarian reserve are exclusive or complementary to identify the best response to follicle development. Methods Retrospective cohort study, involving patients undergoing assisted reproduction treatment at the Instituto de Medicina Reprodutiva e Fetal, from April 2009 to July 2014. Age, biochemical tests, and ultrasound were assessed....

Gastric antral web, also called antral diaphragm, is a rare cause of gastric-outlet obstruction. First described by Touroff et al. in 1940 [1], gastric antral web (GAW) or gastric antral diaphragm is a relatively rare and controversial entity. Both congenital and acquired etiologies have been postulated for this lesion in adults. The congenital theory recognizes that GAW occurs in infants and c...

AIM To evaluate the effects of ginger on gastric motility and emptying, abdominal symptoms, and hormones that influence motility in dyspepsia. METHODS Eleven patients with functional dyspepsia were studied twice in a randomized double-blind manner. After an 8-h fast, the patients ingested three capsules that contained ginger (total 1.2 g) or placebo, followed after 1 h by 500 mL low-nutrient ...

The sustainability and production of collared peccary (Pecari tajacu) has been studied in the last few years; however, further information on its reproduction is necessary for breeding systems success. Understanding folliculogenesis aspects will contribute to effective reproductive biotechniques, which are useful in the preservation and production of wildlife. The aim of this study was-to evalu...

Introduction: The horizontal bony canal in the lateral maxillary wall is the site of anastomosis between the arterial branches from the posterior superior alveolar artery (PSAa) and the infraorbital artery. This anatomic structure is known as the ‘alveolar antral artery’.   Materials and Methods: We performed a literature review. The anatomic location of the alveolar antral artery in the latera...

Helicobacter pylori-infected subjects exhibited a strong decline in antral secretory leukocyte protease inhibitor (SLPI) levels compared to H. pylori-negative subjects and subjects from whom H. pylori had been eradicated (P = 0.002). This reduction was specific for the antrum, whereas SLPI expression in corpus and duodenum was not affected. Antral SLPI levels were inversely correlated with infl...

Previous studies have demonstrated that antral somatostatin exerts inhibitory effects on gastrin cells via paracrine pathways, accomplished by its release from somatostatin-containing cells into the immediate interstitial environment of the gastrin cell. The present studies were directed to examine the effect of somatostatin on gastrin gene transcription in the dog antrum and to determine wheth...
