The Effect of Acute Docosahexaenoic Acid Intake on Left Ventricular Function and Susceptibility to Ischemia-Reperfusion Injury in the Isolated Rat Heart
(University of Waterloo, 2015-10-01)The chronic intake and myocardial incorporation of n-3 highly unsaturated fatty acids (HUFA), particularly docosahexaenoic acid (22:6n-3, DHA), is believed to protect against ischemia-reperfusion injury, possibly through ... -
The Effect of Acute Exercise on Femoral Artery Vasoconstriction: Involvement of Local Vascular Wall Renin-Angiotensin Systems
(University of Waterloo, 2008-09-02)During a single bout of aerobic exercise, blood flow is shunted to exercising tissues while blood flow is maintained or reduced to less metabolically active areas (i.e. splanchnic area and non-working muscles). Although ... -
Effect of acute treadmill exercise and voluntary freewheel running on cytokine and apoptotic protein expression in intestinal lymphocytes of older female C57BL/6 mice
(University of Waterloo, 2011-09-06)Background: Colorectal cancer (CRC) is the second leading cause of Canadian cancer mortality. Inflammation is a fundamental risk factor in the aetiology of sporadic intestinal carcinoma. Reducing the frequency or duration ... -
The Effect of Adverse Childhood Experiences on Depression Symptoms among Older Adults in China
(University of Waterloo, 2019-07-24)Background Depression is not a normal part of aging. However, it is a serious, growing problem for the elderly population of China, where the world’s largest cohort of people aged 60 and over is growing rapidly. Research ... -
Effect of aging on measures of visual attention using dual tasks and visual search
(University of Waterloo, 2010-01-19)In Canada, as baby boomers age, there will be an increase in the percentage of seniors within the general population (Statistics Canada, 2006). Seniors often have difficulty in performing certain everyday tasks and have ... -
The effect of aging on movement characteristics and postural control during stooping and crouching tasks
(University of Waterloo, 2013-12-02)Stooping and crouching (SC) postures are integral to many daily tasks, such as retrieving objects from the floor and reaching to low shelves, yet nearly one in four community-dwelling older adults (24%) report having ... -
Effect of Alloy Composition on the Hot Deformation Behavior, Extrudability and Mechanical Properties of AA6XXX Aluminum Alloys
(University of Waterloo, 2017-08-02)As automotive companies adjust to stricter environmental legislations, there is increased interest in the application of high specific strength alloys such as the AA6xxx aluminum alloys. In the near term, light weighting ... -
The Effect of Aluminum Cold Spray Coating on Corrosion Protection and Corrosion Fatigue Life Enhancement of Magnesium Alloy, AZ31B
(University of Waterloo, 2015-08-18)Magnesium alloys are of a recent interest for the transportation industry due to their excellent properties such as high strength and low density which will save energy and reduce gas emission and it will also improve the ... -
