BACKGROUND AND PURPOSE The effect of delayed transit time is the main source of error in the quantitative measurement of CBF in arterial spin-labeling. In the present study, we evaluated the usefulness of the transit time-corrected CBF and arterial transit time delay from multiple postlabeling delays arterial spin-labeling compared with basal/acetazolamide stress technetium Tc99m-hexamethylprop...

loss of 10 kg over the last year. She reported helping the passage of the food bolus through the subcutaneous presternal digestive conduit with her ngers. A thick-paste barium transit study revealed multiple diverticular pouches in the neoesophagus, with retained contrast material inside of them. No other reason for the weight loss was identi ed. As the dysphagia in this case seemed not to be w...

Address for Correspondence: Linda Pantongrag-Brown, M.D., AIMC, Ramathibodi Hospital, Bangkok 10400, Thailand. The small-bowel feces sign is a finding found at CT of the abdomen. It is defined by the presence of fecal-like material mixed with gas bubbles in the dilated lumen of the small intestine, usually seen prior to the point of obstruction. It is the result of delayed small-bowel transit t...

Intersections are considered as the most critical parts of the bus rapid transit (BRT) system. Transit signal priority is one of the efficient solutions to reduce BRT fleet delays at intersections. The aim of this study is to propose a new algorithm to decrease the BRT fleet delays at actuated intersections, while reducing the negative impacts on different approaches. The adaptive strategy is a...

BACKGROUND Feeding related peptides have been shown to be additionally involved in the central autonomic control of gastrointestinal functions. Recent studies have shown that ghrelin, a stomach-derived orexigenic peptide, is involved in the autonomic regulation of GI function besides feeding behavior. Pharmacological evidence indicates that ghrelin effects on food intake are mediated by neurope...

Transit time is a fundamental catchment descriptor that reveals information about storage, flow pathways and source of water in a single characteristic. Given the importance of transit time, little guidance exists for the application of transit time modeling in complex catchment systems. This paper presents an evaluation and review of the transit time literature in the context of catchments and...

STUDY OBJECTIVES To assess the feasibility of estimating intestinal transit time in the general population using self recorded data on stool form, frequency of defecation, and the interdefecatory time interval. DESIGN Prospective measurement of bowel function. SETTING Bristol, Avon, UK between 1987 and 1989. SUBJECTS Subjects were drawn from 1897 people who comprised 72.2% of a stratified...

Assessment of transit through the gastrointestinal tract provides useful information regarding gut physiology and patho-physiology. Although several methods are available, each has distinct advantages and limitations. Recently, an ingestible wire-less motility capsule (WMC), similar to capsule video endoscopy, has become available that offers a less-invasive, standardized, radiation-free and of...
