The optimal management of locally gastric cancer persists a matter of intense discussion. Frequently cases with esophagogastric cancer are handled with preoperative chemotherapy [the more typical European method] or mixed chemoradiotherapy. The present research examines a comparison of overall retention and disease-free retention among gastric cancer cases managed via two Adjuvant and Neoadjuva...

The effect of toxin-gamma from Tityus serrulatus scorpion venom on the gastric emptying of liquids was studied in 176 young adult male Wistar rats (2-3 months of age) divided into subgroups of 8 animals each. Toxin-gamma was injected i.v. at doses of 25, 37.5, 50 or 100 micrograms/kg and the effect on gastric emptying was assessed 30 min and 8 h later. A time-course study was also performed by ...

OBJECTIVE To define the predictors of the rate of gastric emptying in patients with diabetes. RESEARCH DESIGN AND METHODS A total of 101 outpatients with diabetes (79 type 1 and 22 type 2) underwent measurements of gastric emptying of a solid/liquid meal (scintigraphy), upper gastrointestinal symptoms (questionnaire), glycemic control (blood glucose concentrations during gastric emptying meas...

Physical exercise, mainly after vigorous activity, may induce gastrointestinal dysmotility whose mechanisms are still unknown. We hypothesized that physical exercise and ensuing lactate-related acidemia alter gastrointestinal motor behavior. In the present study, we evaluated the effects of short-term exercise on gastric emptying rate in awake rats subjected to 15-min swimming sessions against ...

The purpose of writing this review on floating drug delivery systems (FDDS) was to compile the recent literature with special focus on the principal mechanism of floatation to achieve gastric retention. The recent developments of FDDS including the physiological and formulation variables affecting gastric retention, approaches to design single-unit and multiple-unit floating systems, and their ...

The present review on floating drug delivery systems (FDDS) is aimed to compile the recent literature with special focus on the principal mechanism of floatation to achieve gastric retention. The recent developments of FDDS such as physiological and formulation variables affecting gastric retention, approaches to design single-unit and multiple-unit floating systems, and their classification an...

The early results of a prospective randomized clinical trial of selective proximal vagotomy with and without gastric drainage in a total of 36 patients are reported. In spite of adequate average acid reduction and little evidence of gastric retention two definite recurrent ulcers have occurred in the 16 patients who did not have a pyloroplasty. Further trials of the effect of selective proximal...

BACKGROUND/AIMS Gastric stasis in migraineurs remains controversial. The aim of this study is to investigate gastric emptying (GE) time, and any associations between GE parameters and dyspeptic symptoms among patients with functional dyspepsia (FD) and migraine without any gastrointestinal symptoms during the interictal period. METHODS We enrolled 27 migraine patients, 32 FD patients and 12 h...

The results of vagotomy and simple drainage for recurrent benign lesser curve gastric ulcer are recorded. Seventy-two consecutive cases were treated from 1962 to 1965. The follow-up is therefore from five to eight years. In only two cases did the ulcer fail to heal and remain healed. Four years after operation both these had persistent ulceration and persistent gastric retention. Both have appa...
