Background: The appropriate colon cleansing is a major determinant of quality of colonoscopy. The aim of this study was to compare the efficacy and tolerability of the morning (AM) PEG (polyethylene glycol) solution to previous-evening (PM) PEG solution for the afternoon colonoscopy. Methods: This comparative study compared the AM to PM prep for afternoon outpatient colonoscopy. The subjects r...

The reload cost spanning tree problem (RCSTP) is an NP-hard problem, where we are given a set of nonnegative pairwise demands between nodes, each edge is colored and a reload cost is incurred when a color change occurs on the path between a pair of demand nodes. The goal is to find a spanning tree with minimum reload cost. We propose a tree-nontree edge swap neighborhood for the RCSTP and an ef...

AIMS To evaluate safety and effectiveness of clopidogrel reloading in patients on chronic clopidogrel therapy undergoing percutaneous coronary intervention (PCI). METHODS AND RESULTS Five hundred and three patients on >10 days clopidogrel therapy (41% with non-ST-segment elevation acute coronary syndrome, ACS) randomly received 600 mg clopidogrel loading 4-8 h before PCI (n = 252) or placebo ...

Studies were conducted to assess population densities and phenology of the psyllid Diaphorina citri Kuwayama at two citrus groves in east-central Florida. One grove contained young, irrigated grapefruit trees and the other contained mature, nonirrigated orange trees. The two groves were sampled weekly for eggs, nymphs, and adults on flush shoots; for adults on mature leaves; and for adults capt...

KEY POINTS A post-menopausal hot flush consists of profuse physiological elevations in cutaneous vasodilatation and sweating that are accompanied by reduced brain blood flow. These responses can be used to objectively quantify hot flush severity. The impact of an exercise training intervention on the physiological responses occurring during a hot flush is currently unknown. In a preference-cont...
