Enteral nutrition is not widely accepted.in the management of severe colitis, partly because of the reported impaired absorption in the small intestine.' Transit of food through the small intestine, however, is prolonged in patients with active ulcerative colitis,2 which should enhance small bowel absorption by increasing the time of contact between food and small bowel mucosa. We have re-evalu...

Temporal coordination of services, as a crucial aspect of integration in public transport systems, has always been a big concern for transit planners and schedulers. One of the major issues in the way of coordinating transit services is the lack of a robust measure of effectiveness for assessing the quality of temporal coordination in public transport systems. Even though the network-wide summa...

BACKGROUND/AIMS Achalasia is a primary motility disorder of esophagus. Many parameters represent esophageal function and morphologic changes, but their interrelationship is not yet established. We hypothesized that esophageal body would need to generate unusual pressure to empty the food bolus through the non-relaxing lower esophageal sphincter in patients with achalasia; therefore, higher is t...

assessment of colonic transit time (ctt) in patients with chronic constipation

About 20% of the population suffer from constipation. For the common types of functional constipation, idiopathic and IBS related constipation, the proportion of women is about 80-90%. It is important to structure the management of this large patient group. The duration of symptoms is of relevance. In general, a long history allows for more restricted investigations, and the management can be f...

This study aimed to evaluate the effects of food texture and viscosity on the swallowing function by measuring tongue pressure and performing a videofluorographic (VF) examination. Eleven normal adults were recruited for this study. Test foods with different consistencies and liquid contents, i.e., a half-solid nutrient made of 0.8 and 1.5% agar powder, syrup, and a liquid containing 40 wt/vol%...

Food deserts-areas with a significant low-income population experiencing low accessibility to healthy food sources-have been well studied in terms of their connection to obesity and its related health outcomes. Measuring food accessibility is the key component in food desert research. However, previous studies often measured food accessibility based on large geographic units (e.g. census tract,...

local bus network is the most popular transit mode and the only available transit mode in the majority of cities of the world. increasing the utility of this mode which increases its share from urban trips is an important goal for city planners. timetable setting as the second component of bus network design problem (network route design timetable setting vehicle assignment crew assignment) hav...
