Studies of gastric emptying in man
Measurements of gastric emptying in man have "been made 'by scintigraphic methods "based on a rectilinear scanner or gamma camera. Xn. the initial studies with a scanner. indium-113m DTPA was evaluated as a possible radionuclide marker for a test meal and was found to be satisfactory. …

Delayed gastric emptying in Ivor Lewis Gastro-oesophagectomy
Delayed gastric emptying(DGE) affects 17.5% of Ivor Lewis Gastro-oesophagectomy(ILGO) patients in my unit. DGE diagnosis is varied globally due to definition subjectivity. Definition standardisation along with a diagnostic algorithm will assist clinicians in obtaining accurate diagnoses. …

African starchy foods, gastric emptying, and starch digestion in Malian stunted children
… glucose response and providing sustained energy. Gastric emptying rates of traditional sorghum and millet-based African foods of the Sahelian region (couscous, thick and thin porridges made from millet and/or sorghum) were compared to those of non-traditional "modern" foods that are mostly …

Glycaemic Response in Relation to Gastric Emptying and Satiety in Health and Disease
… are recommended to control blood glucose levels. Gastric emptying, together with other factors, regulate the postprandial blood glucose response. A delay in the gastric emptying rate (GER) leads to a lower postprandial blood glucose concentration. However, 30-50% of diabetes patients have delayed …

Intra-operative Prophylactic Pyloric Balloon Dilatation During Oesophagectomy to Prevent Early Delayed Gastric Emptying
Early delayed gastric emptying (DGE) occurs in 27% of patients undergoing an Oesophagectomy in University Hospital Plymouth (UHP) as per our local definition. It has a profound effect on patients’ recovery and may lead to anastomotic leak and pneumonia. Pyloric balloon dilatation (PBD) is a …

Can polyphenol-rich millets affect glycaemic response, insulinaemic response and gastric emptying in prediabetes?
… of finger-millet muffins (p<0.05). Regarding gastric emptying, significant differences were observed in ascension times (Tasc) (p<0.05) (~21min after control) between wheat and finger millet grain-based muffins consumed. These differences were only observed in the prediabetes group. There was …

The effects of bit chewing on gastric emptying and orocecal transit times in clinically normal horses
… however, a direct effect of bit chewing on gastric emptying time (GET), small intestinal transit time (SITT), and total orocecal transit time (OCTT) has not been investigated. Our objective was to determine whether bit chewing increased small intestinal motility and decreased GE, SITT, and …

Relationships of gastric emptying with glycaemia, insulin secretion and the incretin effect in health and type 2 diabetes
… on the inter-dependent relationships between gastric emptying, incretin hormones (GIP and GLP-1) and postprandial glycaemic and insulinaemic responses in health and type 2 diabetes. Key themes relate to: 1) Evaluation of the relationships of ‘early’ and ‘late’ glycaemic responses with gastric …

A novel nutritional approach to the management of type 2 diabetes: effects of nutritional preloads on postprandial blood glucose and gastric emptying in type 2 diabetes mellitus
… fibre preloads on postprandial blood glucose and gastric emptying in type 2 diabetes mellitus. Key themes relate to: 1) The longitudinal evaluation of gastric emptying in type 2 diabetes 2) The evaluation of gastric emptying as measured by means of a ¹³C-octanoic acid breath test in older adults …

Non-invasive assessment of gastrointestinal function using breath test technology : investigations in health and disease.
Assessment of gastric emptying in animals is hampered by the lack of a technique that is noninvasive and does not involve sacrificing the animal. The primary aims of these studies therefore were to develop the breath test for the mouse and then investigate gastric emptying rates in physiological, …

The use of scintigraphy to study gastric emptying, motility and small intestinal transit in patients who have ingested a selection of common poisons
… of pharmacological doses of many drugs on gastric emptying and motility are known, information on the effects of higher doses is limited. I investigated patients who took overdoses of certain commonly used drugs to determine their effects on gastric emptying and motility and small …

The role of gastric and small intestinal mechanisms in postprandial hypotension.
… from the stomach into the small intestine, while gastric distension attenuates the postprandial fall in blood pressure. The overall aims of the studies described in this thesis were to investigate the pathophysiology of postprandial hypotension, with the particular focus on gastric and small …

Limits to exogenous glucose oxidation by skeletal muscle during prolonged, moderate-intensity exercise in man
… [PPO]) exercise. These include i) the rate of gastric emptying of an ingested fluid, ii) the rate of digestion, absorption and subsequent transport of glucose into the systemic circulation, and iii) the rate of glucose uptake and oxidation by the working muscles. To test the hypothesis that the …

Diagnosis & dietary intervention in patients with diabetic gastroparesis
… DM with gastroparesis. Methods: In Paper I, gastric emptying of radiopaque markers (ROM) from the stomach using fluoroscopy was compared to gastric scintigraphy (current gold standard for diagnosing gastroparesis)) and the link to GI symptom severity was determined. In Paper II, the plasma …

Dietary amino acids and their contribution to de novo lipogenesis
… of changing the solid/liquid ratio of meals on gastric emptying as well as the effect of changing meal compositions on lipid metabolism. A 5-way crossover human study demonstrated that liquid carbohydrate was the main determinant of gastric emptying rate compared to macronutrient composition and …

Glucose metabolism in the critically ill.
… small intestine have the capacity to modulate gastric emptying. Studies were designed to further evaluate hormonal mechanisms underlying gastric emptying. The student established that in health endogenous glucagon-like peptide-1 (GLP-1) slows gastric emptying and glucose absorption, thereby …

Effect of Between-Meal Eating on Stomach Emptying Time
… the effect of eating between meals on stomach emptying time.</p> <p>The effect of between-meal eating on the emptying time of the stomach was studied by roentgenogram on nine apparently normal, healthy adult women between the ages of twenty-one and thirty-five years. The experimental method …
