Ischemic colitis appears to be a collection of diseases rather than a single entity. On the one hand, there is the colitis that truly appears to be caused by a lack of blood flow and, on the other hand, there is the disease that is called "ischemic" for lack of a better diagnosis-the colitis that is more "idiopathic" than "ischemic." Four widely held tenets(More)
The effects of polycyclic aromatic hydrocarbons (PAHs) on microsomal liver enzymes were examined in rainbow trout. Various PAHs (naphthalene through benzo(a)pyrene [B(a)P]) were injected ip to screen for mixed-function oxidase (MFO) activity. Chrysene, B(a)P, and Aroclor 1254 caused MFO induction. When fish were also exposed to solubilized pyrene,(More)
Acknowledgements: We thank Christian Hiller and Marianne Keller for excellent technical assistance. Abstract Sustained expression of cytoprotective intestinal epithelial heat shock proteins (Hsps), particularly Hsp27, depends on stimuli derived from bacterial flora. In this study, we examined the role of the bacterial chemotactic peptide, fMLP, in(More)
OBJECTIVES The objective of this study was to determine treatment outcomes and long-term complications in pediatric patients with Ewing Sarcoma treated at the British Columbia Cancer Agency (BCCA). METHODS A retrospective chart review of 101 pediatric patients (<19 y old) with Ewing Sarcoma diagnosed between 1960 and 2005 was performed. The Kaplan-Meier(More)
Regression testing is an important activity for controlling the quality of a software product, but it accounts for a large proportion of the costs of software. We believe that an understanding of the underlying relationships in data about software systems, including data correlations and patterns, could provide information that would help improve regression(More)
A set of 66 vaels acoustically similar to /ae/ have been synthesized by adding together sinusoidal harmonics of the appropriate frequencies, amplitudes, and phases. Subjects mre asked to estimate the psychophysical distance between each stimulus and a reference vael in a 300-trial randomized test. Normalized subjective distance scores have been computed for(More)
The paper reviews recent progress in the DISC project on developing a systematic and general scheme for in-depth characterisation of current practice in the development and evaluation of spoken language dialogue systems and their components. This scheme consists of a 'grid' which serves to characterise the properties of any particular spoken language(More)
