During the winter of 2000 to 2001, an outbreak due to Salmonella Enteritidis (SE) phage type 30 (PT30), a rare strain, was detected in Canada. The ensuing investigation involved Canadian and American public health and food regulatory agencies and an academic research laboratory. Enhanced laboratory surveillance, including phage typing and pulsed-field gel(More)
A pilot study was undertaken to determine which measures of Quality of Life (QL) would be of most use in the follow-up of patients participating in clinical trials of treatments for head and neck cancer. A total of 96 non-randomized patients who had been treated for head and neck cancer either by surgery (three patients), radiotherapy (54 patients), or(More)
We investigated the sequence requirements for the site-specific DNA cleavages and recombinational genome isomerization events driven by the terminal repeat or a sequence of herpes simplex virus type 1 KOS DNA by inserting a series of mutated a sequences into the thymidine kinase locus in the intact viral genome. Our results indicate that sequences located(More)
We inserted the terminal repeat (a sequence) of herpes simplex virus type 1 (HSV-1) strain KOS into the tk gene of HSV-2 strain HG52 in order to assess the ability of the HSV-1 a sequence to provoke genome isomerization events in an HSV-2 background. We found that the HSV-1 a sequence was cleaved by the HSV-2 cleavage/packaging machinery to give rise to(More)
The Nucleic Acid Sequence-Based Amplification (NASBA) process involves alternate steps of DNA synthesis from an RNA template and RNA synthesis from a DNA template, using avian myeloblastosis virus (AMV) reverse transcriptase and T7 RNA polymerase, respectively. The overall fidelity of the amplification process was determined by sequence analysis of cloned(More)
The host-cell reactivation of V antigen production for irradiated adenovirus was examined in fibroblasts from 5 unrelated patients with Cockayne's syndrome (CS) and 2 CS heterozygotes. The fibroblast cultures were infected with either irradiated or non-irradiated adenovirus and subsequently examined for the presence of viral structural antigens using(More)
The paper describes a used-centred design for the summary screen of a computerised ICU patient data management system (PDMS). The screen also forms the resting state display, or default screen, and provides the principal navigation tool to other functionality within the system. The design process identified the most frequent potential users of this screen(More)
