Neighborhoods often resist public transit expansion for fears that it will increase crime by attracting transient populations and prospecting criminals. On the other hand, transit may reduce crime by altering economic development and other positive features of neighborhoods. Studies examining public transit and crime have either been cross sectional or examined the impact of public transit expa...

BACKGROUND Treatment of acromegaly with octreotide increases the proportion of deoxycholic acid in, and the cholesterol saturation of, bile and induces the formation of gallstones. Prolongation of intestinal transit has been proposed as the mechanism for the increase in the proportion of deoxycholic acid in bile. AIMS To study the effects of octreotide on intestinal transit in acromegalic pat...

We examine the strategic interaction between interconnection and competition in the Internet backbone market. Networks asymmetric in size choose among different interconnection regimes, IP-Transit, Bill-and-Keep Peering, and Paid Peering, and compete for end-users. We show that sufficiently symmetric networks enter a Peering agreement while otherwise use an intermediary network for exchanging t...

This article provides an overview of the influences of motorization trends on urban residents’ travel patterns in the Jakarta Metropolitan Area (JMA) in the last decade. The performance of the first year of the Bus Rapid Transit (BRT) system implementation, as a way to suppress motorization in JMA, is also described. It is found that the trend of motorization has already become a critical issue...

The multimodal trip planning system (MTPS) described in this paper can efficiently identify reasonable journeys. Our methodologies could be implemented in future transit trip information systems. An effective MTPS would be of value to transit agencies or administrators due to the large number of different yet related characteristics of the transit network. In Taiwan, no successful MTPS exists o...

BACKGROUND AND AIMS Several conditions that delay gastrointestinal transit are associated with unconjugated hyperbilirubinaemia. We hypothesised that the gastrointestinal transit time is directly related to plasma unconjugated bilirubin (UCB) concentrations, and that this relationship can be used to develop a new therapeutic strategy for severe unconjugated hyperbilirubinaemia in the Gunn rat m...

BACKGROUND Gastrointestinal (GI) disturbances are often reported by long distance runners and are more common in women, particularly after prolonged high intensity exercise. OBJECTIVES To determine whether these symptoms could be associated with alterations in GI motility. METHODS Small bowel and colonic transit were measured using pH telemetry in a group of 11 female athletes (age 22 to 53...

Previous investigations of stress effects on gastric emptying, orocaecal, and colonic transit in rats have produced conflicting results. Here one type of stressor, a 'passive avoidance' situation, was used to investigate its effects on gastric emptying, orocaecal and colonic transit. After the rats had been trained to eat a standard amount of semisolid food, gastric emptying was determined (n =...

The N-terminal transit peptides of nuclear-encoded plastid proteins are necessary and sufficient for their import into plastids, but the information encoded by these transit peptides remains elusive, as they have a high sequence diversity and lack consensus sequences or common sequence motifs. Here, we investigated the sequence information contained in transit peptides. Hierarchical clustering ...

Objective(s):This study was carried out to investigate the effects of COX-2 selective inhibitor (Celecoxib) or non-selective COX inhibitor (Ibuprofen) on gastrointestinal motility. Materials and Methods: The rats were randomly divided into five groups including: intact, sham, traumatic brain injury (TBI) group (intact rats under TBI), Celecoxib group (10 mg/kg), Ibuprofen group (10 mg/kg). Rats...
