My doctoral work will leverage data from the AYAZAZI study, a longitudinal cohort study which assesses intersecting socio-behavioural, structural, and biomedical HIV risk factors among HIV-negative or HIV-status unknown youth in two South African communities, to examine the biological and psychological consequences of chronic stressors. This internship will be focused on community engagement and relationship […]

La cigarette électronique est un dispositif proposé aux fumeurs pour remplacer la cigarette standard dans le but de réduire-éliminer les effets nocifs de la fumée de cigarette. Cette cigarette électronique a été présentée comme une solution efficace de remplacement, et un moyen sans dangers pour la santé des utilisateurs. Cependant, plusieurs études récentes démontrent que […]

Le projet vise à élucider les mécanismes des douleurs persistantes, et leurs conséquences sur des pathologies émotionnelles associées (anxiété). Notre hypothèse est que les modifications de l’activité des aires cérébrales impliquées dans les douleurs pathologiques et l’anxiété mettent en jeu des voies nerveuses descendantes qui relient le cortex et la moelle épinière. Le projet s’intéresse […]

Le cancer de la bouche fait partie de la maladie maligne du carcinome épidermoïde de la tête et du cou, qui constitue un grave problème de santé publique en raison de son incidence, de sa prévalence et de sa mortalité élevées (Moro JDS et al., 2018). Il est classé au 6e rang mondial des tumeurs […]

Les instruments de mesure (questionnaires) qui sont complétés directement par les personnes permettent une évaluation en adéquation avec le vécu et les expériences de ces personnes. De tels instruments de mesure nécessitent cependant une évaluation approfondie par des experts afin d’assurer la validité du contenu des questions et l’association des questions avec le phénomène qu’il […]

The Senegalese sole is an important species of flatfish in the ecology of coastal ecosystems in southern Europe and North Africa and a staple food source for human consumption throughout its range. It is also a species of great interest for studies of retinal structure and function as it possesses unique photoreceptor distributions that are […]

Imaging of cerebral perfusion (the delivery of blood to a capillary bed in the brain tissue) is significant for diagnosing a variety of diseases. There are multiple challenges associated with perfusion imaging which significantly limits the quality of cerebral perfusion images. I am planning to develop a novel approach of cerebral perfusion magnetic resonance imaging […]

Individuals with post-traumatic stress disorder (PTSD) often struggle to relax, or simply be at ‘rest.’ In particular, recent research has revealed participants with PTSD show hyper-activity across the visual cortex while at rest. Referred to as sensory hyper-activity and disinhibition, altered resting-state patterns are thought to be underlying hypervigilance and re-living sensations clinically, as well […]

During surgery, a neurosurgeon must refer to three levels of image information: macroscopic from the patient’s MRI or CT, providing anatomical context of the surgical target; mesoscopic information from a surgical microscope or exoscope providing a highly magnified view of the region surrounding the surgical target; and the most important microscopic information provided by histology […]

AYAZAZI (meaning ‘Knowing Themselves’ in Zulu) was a CIHR funded youth-centred, multi-site, interdisciplinary, prospective cohort study focused on HIV prevention among 425 adolescents and young adults (aged 16-24 years) residing in Soweto and Durban, who reported HIV-negative or unknown status at enrolment. AYAZAZI is guided by a youth engagement framework, which prioritizes youth-friendly spaces and […]

Breast?conserving surgery (BCS) is a mainstay in breast cancer treatment. For nonpalpable breast cancers, current strategies have limited accuracy, contributing to high tumor-positive margin rates. Perk-Lab developed NaviKnife, a surgical navigation system based on real?time electromagnetic (EM) tracking. The goal of the research project is to confirm the further feasibility of intraoperative EM navigation in […]
