Filter by:The purpose of this study is to assess the dose-related effects of TU-100, a botanical agent that modulates gastrointestinal nerves, on rectal compliance, rectal sensation thresholds and small bowel and colonic transit in female patients with functional constipation as compared to placebo.
- Background: Fasting is mandatory for safety of anesthesia in elective surgery and imaging but gives rise to discomfort, hunger and thirst especially in children. Internationally accepted fasting times are often prolonged because of organisational delay in operating theatre. - Hypothesis: Clear fluids can be ingested until an imaginary anesthesia induction time without enlarging the residual gastric contents compared to overnight fast. There is no difference between residual gastric contents after 4 hours of fasting after a light meal compare to 6 hours in healthy children. - Examination of gastric volume using magnetic resonance imaging after overnight fasting and subsequent scans after either clear fluid intake or intake of a standard breakfast are performed in children aged 6 - 12 years. Time course after fluid intake is followed with scans every half hour for 2 hours. In the breakfast group 4 versus 6 hours fasting time will be simulated, e. g. intake of clear fluid is allowed for 2 versus 4 hours after the meal. Volume of gastric contents will be compared with a standardized ultrasonographic view of the stomach.
The overall aim of this application is to determine the mechanism(s) by which common bariatric surgical procedures alter carbohydrate metabolism. The study proposed will examine the effect of vagal nerve stimulation on insulin secretion and action.
The aim of the study is to determine the effect of dexmedetomidine infusion on gastric emptying and oro-caecal transit time in healthy volunteers, judged by measuring plasma paracetamol concentrations after paracetamol ingestion and pulmonary hydrogen measurement technique after lactulose ingestion. The effects of dexmedetomidine will be compared to the effects of morphine and placebo.
Synthetic GLP-1 lowers postprandial (pp) glycemia by stimulating insulin, inhibiting glucagon, and delaying gastric emptying. However, the effects of the endogenous peptide are largely unknown. Using the specific GLP-1 receptor antagonist exendin(9-39)amide (Ex(9-39)) the investigators recently showed that GLP-1 released during intestinal meal perfusion acts as an incretin hormone and as an enterogastrone. As the relative contributions of these effects to controll postprandial glycemia are unclear, the investigators used Ex(9-39) to investigate the mechanisms of action of GLP-1 after an oral meal in humans.
Background of the study: Plant sterols can play an important role in lowering plasma cholesterol. The extent to which plant sterols can reduce plasma cholesterol levels depends on the intake scenario. We suggest that the difference in these effects depends on gastric emptying and bile secretion. Objective of the study: The aim of this study is to gain insight in the mechanisms that may be involved in the effects of plant sterol drinks on gastric emptying and gallbladder motility. In order to test this, we compare the different effects of the consumption of a plant sterol containing drink prior to, during and after a standardized meal.
This was a phase 1, open-label, randomized study, designed to assess the impact of Moviprep® or Klean-Prep® on gastrointestinal transit. It was performed in two parallel groups with Part A in two groups of four subjects preceding Part B, which was performed in two groups of 12 subjects. Subjects attended a pre-study medical within 28 days of dosing and a post-study medical 5-10 days after the final dose. Within both Part A and Part B, subjects were required to attend the clinical unit for 2 study periods. Part A consisted of a baseline period to determine individual reference times for gastrointestinal transit. Part B was the test period in which gastrointestinal transit following the administration of the test preparations was assessed.
In this study the investigators want to investigate the effect of a short intravenous infusion of Erythromycine on gastric emptying on patients considered "full stomac" and scheduled for Emergency operation. A gastroscopy will be done after intubation to controll the effect of the perfusion.
Doctors at Mayo Clinic are doing this study to learn if pyridostigmine, a drug, affects the speed at which food travels through the stomach, intestines and colon, and if pyridostigmine improves constipation symptoms in patients with diabetes. Pyridostigmine has been approved by the Food and Drug Administration (FDA) for routine clinical use, however, its use as proposed in this study is considered investigational.
