Exploring Differences in Vascular Aging and Cerebrovascular Hemodynamics between Older Adults of White Caucasian and South Asian Origin
(University of Waterloo, 2014-09-23)In Canada, the number of older adults has been on the rise over the past several decades. As the aging population continues to rise, the prevalence of chronic illnesses is projected to correspondingly increase at an ... -
Exploring factors that contribute to between-subject variability of reaction time
(University of Waterloo, 2018-01-22)For well over a century reaction time has provided researchers with a method to quantify information processing speed. Defined as the interval of time between the presentation of a stimulus to the onset of a response, ... -
Exploring interactions between force, repetition and posture on low back joint loading and intervertebral disc injury
(University of Waterloo, 2014-08-26)Low back pain (LBP) affects approximately 80% of the population at some point in their lives, with 65% of cases becoming chronic pain sufferers. Approximately 40% of LBP cases are attributed to intervertebral disc (IVD) ... -
EXPLORING RESPONSES OF OLDER ADULTS TO UNSOLICITED HELP WITH PHYSICAL TASKS: A SOCIAL COGNITIVE THEORY PERSPECTIVE
(University of Waterloo, 2007-09-19)Continually improving population health in the context of increased life expectancy challenges the assumption that aging invariably leads to significant physical decline. Currently, there is a perception that physical ... -
Exploring the Use of Consumer Grade Technology for Kinematic Assessment of the Upper Limb Following a Stroke
(University of Waterloo, 2014-06-23)Upper limb deficits post stroke affect up to 60% of stroke survivors. The assessment of motor deficits post stroke is important for identifying rehabilitation goals and assessing treatment efficacy. Current clinical tools ... -
Factors that Influence Short-term Learning of Visual-Tactile Associations: An Investigation of Behavioural Performance and the Associated Electrophysiological Mechanisms
(University of Waterloo, 2009-10-29)Neuroplasticity is a mechanism whereby the brain changes its configuration and function through experience. Short-term learning (i.e. minutes to hours) is associated with early phases of neuroplasticity whereby the cortical ... -
Firefighter fitness, movement qualities, occupational low-back loading demands and injury potential
(University of Waterloo, 2012-02-21)BACKGROUND and OBJECTIVES: Low-back overexertion injuries represent a large proportion of fireground “strains, sprains and muscular pains” and are a leading cause of disability and early retirement in firefighters. Given ... -
Functional characterization of murine 1-acylglycerol-3-phosphate O-acyltransferase 4 (AGPAT4)
(University of Waterloo, 2015-09-30)The human genome project has allowed for the rapid identification of a large number of protein families based on similarities in their genetic sequences. The acyl-glycerol phosphate acyltransferase (AGPAT) family of enzymes ... -
Glutamate increases glucose uptake in L6 myotubes in a concentration- and time-dependent manner that is mediated by AMPK
(University of Waterloo, 2015-09-29)The majority of studies that have examined the interactions between glutamate, insulin and glucose are in vivo and have focused on the insulin response that is elicited when glutamate is elevated in circulation or in a ... -
Hsp70 Protects Against Peroxynitrite-Induced Inactivation of SERCA2a by Preventing Protein Oxidation and Aggregation
(University of Waterloo, 2008-09-18)The purpose of this study was to examine the effects of exogenous peroxynitrite (ONOO-) on the cardiac isoform of the sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA2a) and to determine if overexpression of heat shock ... -
Hydrogen peroxide is vasoactive in the mesenteric arteries of spontaneously hypertensive rats
(University of Waterloo, 2008-05-22)It is well established that hypertension decreases endothelium-dependent vasomotor function, partially by excessive generation and reduced scavenging of reactive oxygen species (ROS). Nevertheless, at appropriate levels, ... -
The Impact of Training on Naming and Producing Actions to Novel Objects
(University of Waterloo, 2010-05-06)Visual object similarity, action similarity and semantic information are believed to influence both object naming and action production. The Naming and Action Model (NAM) developed by Yoon, Heinke, and Humphreys (2002) ... -
Impairments in glucose and lipid metabolism in breast cancer patients
(University of Waterloo, 2013-01-08)BACKGROUND: Breast cancer patients typically present with unhealthy body composition (high fat mass and low muscularity) near diagnosis. These body composition characteristics often worsen during treatment and ultimately ... -
In Search of Manual Asymmetries in Aging during Performance of Activities of Daily Living: Does Upper Limb Performance Become More Symmetric with Age?
(University of Waterloo, 2013-09-27)Introduction: A common disorder arising most frequently after a left hemisphere stroke is limb apraxia. Limb apraxia is a deficit of skilled movement, such as performance of activities of daily living (ADLs), that is not ... -
IN VITRO AND IN VIVO BIOMECHANICAL INVESTIGATION OF THE CLINICAL PRACTICE OF DISC PROLAPSE PREVENTION AND REHABILITATION
(University of Waterloo, 2007-09-10)Underlying this thesis is the McKenzie school of thought, a physiotherapy approach that teaches clinicians to recommend particular exercises to their clients in an attempt to accelerate recovery/ prevent recurrence of disc ... -
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 ... -
