Four quantitative reverse transcription-PCR (RT-PCR) methods were compared to evaluate the time course of mRNA formation and decay. Mouse fibroblasts (NIH 3T3) transfected with the human beta-globin open reading frame/c-myc 3'-untranslated region chimeric gene under control of the c-fos promoter (fos-glo-myc) were used for serum-inducible transcription. The(More)
DNA probes with conjugated minor groove binder (MGB) groups form extremely stable duplexes with single-stranded DNA targets, allowing shorter probes to be used for hybridization based assays. In this paper, sequence specificity of 3'-MGB probes was explored. In comparison with unmodified DNA, MGB probes had higher melting temperature (T(m)) and increased(More)
Documenting patterns and outcomes of venous thromboembolism (VTE) management and degree of adherence by clinicians to treatment guidelines could help identify remediable gaps in patient care. Prospective, clinical practice-based data from Canadian outpatient settings on management of VTE, degree of adherence with treatment guidelines and frequency of(More)
UNLABELLED The outer membrane (OM) of Gram-negative bacteria provides protection against toxic molecules, including reactive oxygen species (ROS). Decreased OM permeability can promote bacterial survival under harsh circumstances and protects against antibiotics. To better understand the regulation of OM permeability, we studied the real-time influx of(More)
BACKGROUND The use of proton pump inhibitors (PPIs) has been implicated as a potential contributor to the development of Clostridium difficile-associated disease (CDAD) because of the ability of these drugs to substantially reduce the bactericidal effect of gastric acid. This study focused on the impact of PPIs, among other known risk factors, during an(More)
Antibodies against peripheral nicotinic acetylcholine receptors (nAChR) were used to determine the proportion of brain ?-bungarotoxin binding sites that are immunologically related to the peripheral nAChR. The ?-bungarotoxin binding component partially purified from rat brain was labelled with [(125)I]?-bungarotoxin and reacted with increasing(More)
Venous thromboembolism (VTE) causes significant morbidity and mortality in hospitalized medical populations; however, medical patients do not currently receive thromboprophylaxis beyond their hospital stay. We reviewed the real-life occurrence of VTE-related care for 100 days post-hospitalization in Calgary, Canada. Using medical visit records with a unique(More)
A unique association between actin filament bundles and gap junctions in cortical fiber cells of human and monkey lenses was studied with thin-section electron microscopy and immunocytochemistry. Thin-section electron microscopy showed that distinct layers of filament bundles (approximately 55 nm thick) were consistently associated with fiber gap junctions(More)
Zonulae adherens and associated actin bundles (ZA/AB) are believed to play a major role in epithelial folding and invagination during morphogenesis of neural tube and other vesicular structures. The lens morphogenesis is associated with the formation of the lens vesicle in which ZA/AB would be needed during the formation process. However, the existence of(More)
Triplex-forming oligonucleotides (TFOs) bind sequence-specifically in the major groove of double-stranded DNA. Cyclopropapyrroloindole (CPI), the electrophilic moiety that comprises the reactive subunit of the antibiotic CC-1065, gives hybridization-triggered alkylation at the N-3 position of adenines when bound in the minor groove of double-stranded DNA.(More)
