Strongyloidiasis, which is caused by the nematode Strongyloides stercoralis, is a common and persistent infection, particularly in developing countries. In the setting of compromised cellular immunity, it can result in fulminant dissemination with case-fatality rates of over 70%. The majority of new Canadian immigrants come from countries where(More)
Clinical antimicrobial susceptibility breakpoints are used to predict the clinical outcome of antimicrobial treatment. In contrast, microbiologic breakpoints are used to identify isolates that may be categorized as susceptible when applying clinical breakpoints but harbor resistance mechanisms that result in their reduced susceptibility to the agent being(More)
DNA methylation, which often occurs at the cytosine residue of cytosine-guanine dinucleotides, is critical for the control of gene expression and mitotic inheritance in eukaryotes. DNA methylation silences gene expression either by directly hindering the access of transcription factors to the target DNA, or through recruitment of histone deacetylases to(More)
The 2003 outbreak of severe acute respiratory syndrome took the province of Ontario, Canada, by surprise. A lack of planning and the decentralised nature of the health-care system meant that disruptive control measures had to be put in place to control the outbreak. Several of the control strategies were difficult to implement and resulted in considerable(More)
Physicians can expect to see more mycobacterial bone and joint disease in North America as a result of increased travel, immigration, and use of immunosuppressive medications. The first step in treating infections caused by these organisms is to consider the diagnosis early in the course of illness. Long-standing untreated mycobacterial infections typically(More)
ANKRD11 is a putative tumour suppressor gene in breast cancer, which has been shown in our laboratory to be a co-activator of p53. Our data suggest that down-regulation of ANKRD11 is associated with breast tumourigenesis. Breast cancer cell lines treated with DNA demethylating agents resulted in up-regulation of ANKRD11 expression suggesting that promoter(More)
Despite the potential of improving the delivery of epigenetic drugs, the subsequent assessment of changes in their epigenetic activity is largely dependent on the availability of a suitable and rapid screening bioassay. Here, we describe a cell-based assay system for screening gene reactivation. A cell-based assay system (EPISSAY) was designed based on a(More)
