Agencies at the federal, state and local level are aiming to enhance the public transportation system (PTS) as one alternative to alleviate congestion and to cater to the needs of captive riders. To effectively act as a viable alternative transportation mode, the system must be highly efficient. One way to measure efficiency of the PTS is connectivity. In a multimodal transportation system, tra...

This thesis develops a methodology for solving the bus network design problem (BNDP) in which one seeks to determine the best configuration of bus routes and their frequencies, given information on the bus transit demand, the street network, the available resources and the operational constraints. The proposed methodology follows a heuristic approach and consists of two main components route ge...

introduction: renal dynamic study is a well-established and popular test in routine practice of nuclear medicine. the test is non-invasive, rapid and unique in evaluation of the kidney function. in despite of its clinical values, the parameters derived from renogram are physiologically meaningless. that is due to the fact that renogram is not the true kidney function. from mathematical points o...

BACKGROUND/AIMS Swallowing is a complex function with the control of the swallowing center being located in the brain stem. Our aim in this investigation was to evaluate, in healthy volunteers, the oral and pharyngeal transit of 2 bolus volumes and 2 consistencies, and the influence of these boluses on the proportion of pharyngeal clearance duration/hyoid movement duration. METHODS Videofluor...

Although acute stress accelerates colonic transit, the effect of chronic stress on colonic transit remains unclear. In this study, rats received repeated restraint stress (chronic homotypic stress) or various types of stress (chronic heterotypic stress) for 5 and 7 days, respectively. Vehicle saline, oxytocin (OXT), OXT receptor antagonist or corticotropin-releasing factor (CRF) receptor antago...

AIM To define the role of small-bowel transit time in the detection rate of significant small-bowel lesions. METHODS Small-bowel capsule endoscopy records, prospectively collected from 30 participating centers in the Lombardy Registry from October 2011 to December 2013, were included in the study if the clinical indication was obscure gastrointestinal bleeding and the capsule reached the cecu...

Mizuta, Yohei, Toku Takahashi, and Chung Owyang. Nitrergic regulation of colonic transit in rats. Am. J. Physiol. 277 (Gastrointest. Liver Physiol. 40): G275–G279, 1999.— Nitric oxide has been shown to be an inhibitory neurotransmitter in the mammalian colon, although its role in colonic transit remains unclear. We investigated the effect of the nitric oxide biosynthesis inhibitor NG-nitro-L-ar...

n a series of elegant studies reported in this issue of ICellular and Molecular Gastroenterology and Hepatology, Anitha et al report that a high-fat diet results in slowing of gastrointestinal transit (by geometric center of fluorescein isothiocyanate distribution after gavage), total gastrointestinal transit (by first arrival of a blue dye in stool), and distal colonic transit (by the time tak...
