Can Altering Hip Joint Fluid Volume and Intra-Capsular Pressure Influence Muscle Activation Patterns? Neuromuscular Implications on Clinical Practice
(University of Waterloo, 2011-05-03)Although the integrated relationship that exists between the lumbar spine and hip joints is frequently acknowledged in scientific journals and by medical professionals, specific functional and injury relationships, are ... -
Cardiac motion simulation in cadavers and carotid artery longitudinal wall behaviour
(University of Waterloo, 2023-12-21)Carotid artery longitudinal motion (CALM) is a bidirectional, multiphasic motion of the intima-media complex of the common carotid artery (CCA) wall. This motion has exhibited changes with aging, elevated cardiovascular ... -
Cardiovascular Deconditioning Resulting from 28-hour Bed-rest and the Efficacy of the Fluid Loading Countermeasure
(University of Waterloo, 2010-01-11)This study tested the hypotheses that 1) 28h head-down bed-rest (HDBR) would result in significant hypovolemia and cardiovascular deconditioning, and that 2) NASA’s fluid loading protocol (ingestion of 15 ml/kg water with ... -
Cardiovascular responses of women to orthostatic stress, the effects of the menstrual cycle and age, and a comparison to men
(University of Waterloo, 2010-08-10)Young women are known to exhibit a greater incidence of orthostatic hypotension than men. The exact mechanisms for this are unclear and it has been proposed to be related to cardiac filling, peripheral resistance, and/or ... -
Cause or Consequence? The Interrelationship Between Physical Activity and Fractures
(University of Waterloo, 2021-08-30)Our study characterized the physically active and non-active circumstances during which fractures occur and explored long-term effects on physical activity following one or more fractures of the hip or pelvis, spine, upper ... -
Central Nervous System Control of Dynamic Stability during Locomotion in Complex Environments
(University of Waterloo, 2006)A major function of the central nervous system (CNS) during locomotion is the ability to maintain dynamic stability during threats to balance. The CNS uses reactive, predictive, and anticipatory mechanisms in order to ... -
Cerebral Autoregulatory Response to Postural Changes and Walking in Older Adults with Heart Failure
(University of Waterloo, 2019-09-18)Individuals with heart failure (HF) have reduced cerebral blood flow (CBF) compared to age- matched older adults. This might be related to an impairment in cerebral autoregulation (CA), or an impairment in the CA mechanisms ... -
Cerebral Blood Flow Response to Posture Transition and Walking in Older Adults with Heart Failure
(University of Waterloo, 2019-08-29)Individuals with heart failure (HF) have lower cerebral blood flow (CBF) and oxygenation at rest, and lower cerebral oxygenation at peak exercise, likely due to insufficient cardiac output and poor respiratory function; ... -
Cerebrovascular and cardiovascular responses to lower body negative pressure and posture change in the elderly
(University of Waterloo, 2012-08-27)Lower body negative pressure (LBNP) is frequently used in the research setting as a means to induce orthostatic stress. This tool is applicable to typical movements during daily living only if the associated responses are ... -
Cerebrovascular hemodynamics in older adults: Associations with lifestyle, peripheral vascular health and functional decline
(University of Waterloo, 2013-04-25)In today’s aging population, cerebrovascular health plays a pivotal role in maintaining independence. The identification of early markers of change might help to plan more appropriate preventative and/or therapeutic measures. ... -
Cerebrovascular Hemodynamics, Postural Stability, Gait Dynamics, and Falls in Older Adults
(University of Waterloo, 2018-04-26)Injurious falls in community-living older adults are associated with standing up suggesting that cerebral hypoperfusion following a postural transition might be a contributing factor. A large population study has recently ... -
Changes in Conduit Artery Blood Flow and Diameter Post Blood Flow Restriction
(University of Waterloo, 2011-04-19)Flow mediated dilation (FMD) is a non-invasive test that assesses endothelial health and nitric oxide bioavailability; it is commonly used to examine changes in vascular health due to disease or de-conditioning. Currently, ... -
Changes in Physical Activity, Physical Function and Cognitive Function with Transition to Retirement Living
(University of Waterloo, 2014-08-01)Physical activity is associated with slower physical and cognitive decline with aging. However, there are many barriers to physical activity among community-dwelling older adults. Retirement living may facilitate physical ... -
Changes in whole-blood PUFA and their predictors during recovery from severe acute malnutrition
(Cambridge University Press, 2016-05-28)Children with severe acute malnutrition (SAM) with complications require in-patient management including therapeutic feeding. Little attention has been given to the effects of these feeds on the essential fatty acid status ... -
Characterization of a novel truncated isoform of murine AGPAT4 arising from predicted splice variants
(University of Waterloo, 2021-06-02)The acylglycerophosphate acyltransferase (AGPAT)/lysophosphatidic acid acyltransferase (LPAAT) family of enzymes is responsible for the conversion of lysophosphatidic acid (LPA) to phosphatidic acid (PA), a precursor of ... -
Characterization of Changes in the Kidney, Liver, and Adipose Tissue of RTSAKO Mice
(University of Waterloo, 2018-11-02)Our laboratory has developed a novel genetic mouse model with kidney-specific lipid accumulation called RTSAKOs. The principle aim of my thesis was to study differences in the expression of genes and proteins related to ... -
Characterization of murine HRASLS-1: transcript variant analysis, metabolic regulation, developmental expression, and a role in inflammation
(University of Waterloo, 2014-08-27)N-acylethanolamides (NAE) are involved in a variety of biological processes ranging from fat oxidation to inflammation mediation. Recently, the HRASLS family, a group of class II tumour suppressor proteins, have been ... -
Characterization of the critical biochemical and physiological role of 1-acylglycerol-3-phosphate-O-acyltransferase 4 (AGPAT4) in white adipose tissue
(University of Waterloo, 2016-08-18)White adipose tissue (WAT) is an endocrine and lipid storage organ that is imperative to mammals for the maintenance of energy homeostasis. WAT depot size and triacylglycerol (TAG) content is determined by the regulation ... -
