colon transit time study with radio opaque markers is a simple method for assessment of colon motility disorder in patients with chronic idiopathic constipation. appendicitis caused by metallic objects has been reported repeatedly and is very important because of its complications. we report a case of acute appendicitis that was induced by impaction of radio opaque markers after colon transit t...

Severe idiopathic constipation can be categorised based on physiological testing into subgroups including slow transit constipation and pelvic floor dysfunction. This study aimed to determine if colonic and psychological symptoms, or rectosigmoid transit times, could discriminate among these subgroups. Patients, categorised according to total colonic transit times and pelvic floor function test...

introduction: functional constipation is one of the most common gastrointestinal symptoms which could affect patients’ quality of life. the colonic transit time test could be used for determining functional constipation subtypes. the aim of our study was to determine the abnormalities of the subtypes of functional constipation using ctt. methods and materials: this cross-sectional study was per...

In this paper a novel direct adaptive fuzzy system is proposed to control flexible-joints robot including actuator dynamics. The design includes two interior loops: the inner loop controls the motor position using proposed approach while the outer loop controls the joint angle of the robot using a PID control law. One novelty of this paper is the use of a PSO algorithm for optimizing the contro...

Little is known about how milk proteins affect gastrointestinal (GI) transit, particularly for the elderly, in whom digestion has been observed to be slowed. We tested the hypothesis that GI transit is faster for whey than for casein and that this effect is accentuated with hydrolysates, similar to soy. Adult male rats (18 months old) were fed native whey or casein, hydrolyzed whey (WPH) or cas...

Demand-Adaptive Systems (DAS) display features of both traditional fixed-line bus services and purely on-demand systems such as dial-a-ride, that is they offer demand-responsive services within the framework of traditional scheduled bus transportation. A DAS bus line serves, on one hand, a given a set of compulsory stops according to a predefined schedule specifying the time windows associated ...

Inadequate transportation has emerged as a major bamer to employment for welfare reelplents required to tranmtlon from pubhc assistance to employment under welfare reform. Transportatmn is a particularly daunting barrier for single women without access to a household car This study uses multivariate techmques to examine whether nearby transit access impacts the emplobanent outcomes of th~s popu...

Public transit is an important tool for those looking to ease their commutes, reduce their car dependence, or perhaps minimize their environmental impact. Unfortunately, the usability of transit systems often leaves much to be desired, to the point of deterring new riders. Tools on the web and mobile devices are increasingly being used to help tame confusing transit systems. OneBusAway is one s...
