Influence of acute and chronic glutathione manipulations on coronary vascular resistance and endothelium dependent dilation in isolated perfused rat hearts
(University of Waterloo, 2011-01-25)Glutathione (GSH), a 3-amino acid compound is ubiquitously expressed in eukaryotic cells and is the most abundant low molecular weight thiol. The importance of GSH is highlighted by its multitude of effects. Within the ... -
Influence of AMPK and ROCK Inhibition on Contractile Responses in Isolated Carotid Arteries in Adult and Aged WKY and SHR Rats
(University of Waterloo, 2014-08-28)AMP-activated protein kinase (AMPK) is emerging as an important regulator of vascular function and is proven to affect vascular tone. Here we investigate how AMPK inhibition in arteries from both young and aged normotensive ... -
The influence of an acute bout of aerobic exercise on cortical contributions to motor preparation and execution
(University of Waterloo, 2013-02-01)Increasing evidence supports the use of physical activity for modifying brain activity and overall neurological health (Hillman et al, 2008). Specifically, aerobic exercise appears to improve cognitive efficacy with regards ... -
Influence of area 5 on primary motor cortex: a paired-pulse TMS investigation in healthy adults
(University of Waterloo, 2010-10-27)The neural correlates that underpin fine motor control of the hand and their connections with the primary motor cortex (M1) require further investigation. Brodmann’s area 5 located in the superior parietal lobule (SPL) is ... -
The influence of body mass on posture, pressure distribution and discomfort during prolonged driving.
(University of Waterloo, 2007-09-27)Background: Currently, if traveling the posted speed limit, the typical commuter driver in the Toronto Metropolitan area will travel round trip upwards of 60 minutes a day to work (Heisz and LaRochelle-Cote, 2005). As ... -
The influence of body orientation relative to gravity on egocentric distance estimates in immersive virtual environments
(University of Waterloo, 2022-01-26)Virtual reality head mounted displays (VR-HMD) are a flexible tool that can immerse individuals into a variety of virtual environments and can account for an individuals head orientation within these environments. Additionally, ... -
The Influence of Dual-tasking on Cortical Responses Associated with Instability
(University of Waterloo, 2017-10-12)Recent literature has revealed evidence of cortical involvement in reactive balance control. Using electroencephalography, event-related potentials (ERP) have been shown to be consistently evoked in response to a perturbation ... -
The influence of increased passive stiffness of the trunk and hips on balance control during reactive stepping
(Elsevier, 2019-07)Background Age-related changes, which include increased trunk and hip stiffness, negatively influence postural balance. While previous studies suggest no net-effect of trunk and hip stiffness on initial trip-recovery ... -
The Influence of Low-Load High-Repetition Resistance Exercise and Sex on the Metabolic Properties of Skeletal Muscle
(University of Waterloo, 2020-02-04)INTRODUCTION. The findings of exercise trials have shown that women are better able to initiate aerobic metabolism and are less reliant on anaerobic energy stores. The effect that LL-HR resistance exercise and sex has on ... -
The Influence of Q-Angle and Gender on the Stair-Climbing Kinetics and Kinematics of the Knee
(University of Waterloo, 2007-09-27)Background: Knee joint motion and quadriceps activity play a crucial role in all lower limb tasks, especially those which are highly dynamic and weight-bearing. Due to anatomical differences between men and women such as ... -
The Influence of Social Engagement on Exercise-Associated Cognitive and Affective Changes in Older Adult Women
(University of Waterloo, 2019-08-20)Single bouts of aerobic exercise appear to elicit improvements in cognition and affect among older adults, which are dependent on exercise dose (intensity, duration). Social engagement, not typically considered in exercise ... -
The Influence of the Tensile Material Properties of Single Annulus Fibrosus Lamellae and the Interlamellar Matrix Strength on Disc Herniation and Progression
(University of Waterloo, 2009-07-30)Low back pain is highly prevalent in the developed world, with 80% of the population being affected at some point in their lives. Herniation, a common injury to the intervertebral disc, is characterized as the posterior ... -
Interplay between Autophagy and Apoptosis During Skeletal Muscle Differentiation
(University of Waterloo, 2020-07-07)Our previous studies showed that autophagy regulates apoptosis and is required for proper skeletal muscle differentiation. Previously, we inhibited autophagy in C2C12 cells using 3MA (3-methyladenine) treatment or shRNA ... -
Intervertebral Disc Height Loss and Restoration: Outcomes and Implications
(University of Waterloo, 2016-01-18)This thesis is unified around the theme of disc height loss. Current knowledge in the area of spine research identifies mechanical overload as the culprit for the initiation of injury to the spine. While genetic ... -
Intra- and interhemispheric cortical adaptations due to modulations of premotor and primary motor cortices
(University of Waterloo, 2014-02-21)Movement training modulates the excitability in several cortical and subcortical areas. Compared to training with a single arm, movement training with both arms yields a greater increase in motor related cortical regions. ... -
Investigating cerebellar contributions to sensory processing
(University of Waterloo, 2020-04-21)Over the last two decades, the long-standing view of the cerebellum as a motor structure has been challenged with evidence highlighting the presence of cerebellar activation during non-motor tasks and functional connectivity ... -
Investigating cerebellar modulation of premotor inhibitory control during motor adaptation
(University of Waterloo, 2022-08-02)Motor adaptation is marked by neurophysiological changes in the motor cortex; however, other regions of the motor network such as the cerebellum and premotor cortex also contribute to this process. Enhancing cerebellar ... -
