Drug-related stimuli, through conditioning, are thought to acquire incentive motivational properties that code possible reward availability and elicit an attentional bias, possibly through increased "bottom-up" neural processing. The processes underlying this attentional bias are considered important in the maintenance of addiction, and crucially, in(More)
A topical microbicide reduces the probability of virus transmission when applied to the vagina or rectum of a person at risk of sexually acquiring HIV-1 infection. An effective microbicide could significantly reduce the global spread of HIV-1, particularly if women were able to use it covertly to protect themselves. A microbicide could target the incoming(More)
Perilipin A coats the lipid storage droplets in adipocytes and is polyphosphorylated by protein kinase A (PKA); the fact that PKA activates lipolysis in adipocytes suggests a role for perilipins in this process. To assess whether perilipins participate directly in PKA-mediated lipolysis, we have expressed constructs coding for native and mutated forms of(More)
Sox2 is a high-mobility transcription factor that is one of the earliest markers of developing inner ear prosensory domains. In humans, mutations in SOX2 cause sensorineural hearing loss and a loss of function study in mice showed that Sox2 is required for prosensory formation in the cochlea. However, the specific roles of Sox2 have not been determined.(More)
A large proportion of age-related hearing loss is caused by loss or damage to outer hair cells in the organ of Corti. The organ of Corti is the mechanosensory transducing apparatus in the inner ear and is composed of inner hair cells, outer hair cells, and highly specialized supporting cells. The mechanisms that regulate differentiation of inner and outer(More)
BACKGROUND Disordered eating attitudes and behaviours are common in older teens and young women in Western countries. Recent evidence suggests that the prevalence of these disorders is rising and that the age of onset has fallen. In the present study, disturbed eating attitudes and behaviours were evaluated in a large school-based population in Ontario in(More)
OBJECTIVE The primary objective of this study was to evaluate the effectiveness of a couples intervention in improving marital functioning in advanced cancer patients and their spouse caregivers. A secondary objective was to determine its impact on other symptoms of psychosocial distress and its feasibility and acceptability as a clinical intervention. (More)
The present study examines the association between disease-related factors, perceived social support, attachment security (i.e. attachment anxiety and avoidance), and the occurrence of depressive symptoms in a sample of patients with metastatic gastrointestinal or lung cancer. Results from a sample of 326 cancer outpatients with advanced disease indicate(More)
CONTEXT Proxy ratings, if valid, may provide an alternative approach to evaluating patient quality of life (QoL) at the end of life. OBJECTIVES To examine agreement between terminally ill cancer patients' self-reported QoL and proxy assessment of patient QoL by their family caregiver (FCG) and palliative care physicians (PCPs) at two time points.

Klebsiella pneumoniae is an important cause of urinary tract infection (UTI), but little is known about its pathogenesis in vivo. The pathogenesis of the K. pneumoniae cystitis isolate TOP52 was compared to that of the uropathogenic Escherichia coli (UPEC) isolate UTI89 in a murine cystitis model. Bladder and kidney titers of TOP52 were lower than those of(More)
