Acute Regulation of Vascular Tone by AMP-activated Protein Kinase in Arteries of Healthy, Hypertensive and Aged Rats
(University of Waterloo, 2011-12-21)Background, Rationale and General Purpose: Several seminal observations suggest that AMPK mediates vascular tone: 1) in endothelial cell culture and in vitro isolated protein experiments, activation of AMPK stimulates ... -
Age-related changes in the control of mediolateral dynamic stability during volitional and reactive stepping
(University of Waterloo, 2012-04-23)The high incidence of falls and fall-related injuries among Canadians over the age of 65 continues to be a key public health issue. As the current proportion of individuals within this cohort of the population is predicted ... -
The aging spine: The effect of cyclic loading, simulated degeneration and prolonged sitting on joint stiffness across age
(University of Waterloo, 2018-08-22)Background: Low back pain is estimated to have a lifetime prevalence as high as 84%, and both the severity and frequency of low back pain reporting have a dependency on age. The nucleus pulposus and annulus fibrosis of ... -
Agpat4/Lpaat delta deficiency highlights the molecular heterogeneity of epididymal and perirenal white adipose depots
(American Society for Biochemistry and Molecular Biology, 2017-10-01)Acylglycerophosphate acyltransferase 4 (AGPAT4)/lysophosphatidic acid acyltransferase delta catalyzes the formation of phosphatidic acid (PA), a precursor of triacylglycerol (TAG). We investigated the effect of Agpat4 gene ... -
Analysis of high and low physical functioning breast cancer survivors within two years of treatment
(University of Waterloo, 2017-08-29)The five year survivorship rate of females diagnosed with breast cancer is 88% across Canada (Canadian Cancer Society, 2015). Often, treatments can cause damage to the tissue which may lead to impairment of upper limb ... -
Analysis of the effect of rotator cuff impingements on upper limb kinematics in an elderly population during activities of daily living
(University of Waterloo, 2010-02-18)Despite a large prevalence of rotator cuff impingements or tears in the elderly population, little research has focused on understanding how this population adapts to perform tasks of daily living. Past research has focused ... -
Analysis of Transcranial Doppler Ultrasound Waveform Morphology for the Assessment of Cerebrovascular Hemodynamics
(University of Waterloo, 2012-08-29)The use of transcranial Doppler (TCD) ultrasound for the assessment of cerebral blood flow velocity (CBFV) provides an indication of cerebral blood flow assuming the diameter of the insonated vessel remains constant. Studies ... -
Anticipatory planning in object manipulation: A cross-sectional investigation of children, young adults and older adults
(University of Waterloo, 2016-08-25)Over a series of five studies, this work aimed to investigate anticipatory planning in object manipulation across the human lifespan. Main objectives were to: (a) understand the influence of the movement context; (b) ... -
Aperture Crossing in Challenging Environments: An Examination of the Factors that Influence the Passability of Narrow Spaces
(University of Waterloo, 2016-04-13)In order to get to where we need to go, locomotion often involves walking through narrow spaces. Whether an aperture affords passage is thought to be determined by the body size/aperture size relationship. For normal, ... -
Apoptotic signalling and structural alterations in autophagy-deficient murine skeletal muscle
(University of Waterloo, 2014-10-15)Autophagy is a catabolic process by which the cell targets and degrades cytoplasmic materials, such as proteins and organelles. Autophagy is required for the control of muscle mass under catabolic conditions, but is also ... -
Arm posture influences on regional supraspinatus and infraspinatus activation in isometric arm elevation efforts
(Elsevier, 2019-02)This study aimed to evaluate the effect of arm posture on activation of the anterior and posterior regions of supraspinatus and the superior and middle regions of infraspinatus during resisted isometric arm elevations. ... -
Assessing pre-existing movement and muscular recruitment differences in prolonged standing, transient low back pain developers compared to non-pain developers
(University of Waterloo, 2018-09-26)Epidemiological studies have reported occupational prolonged standing to be associated with low back pain (LBP). Studies that have conducted simulations of prolonged standing work in healthy individuals have demonstrated ... -
Assessing Workers’ Ability to Recognize Lifting Risk Factors for Low Back Pain: Investigating the Efficacy of a Simple Educational Message.
(University of Waterloo, 2015-12-21)Introduction: Participatory ergonomic approaches have been shown to be an effective method for identifying work place hazards. Since in many workplaces, expertise in ergonomics is not available, simple educational messages ... -
An Assessment of the Interplay between the Shoulders and the Low Back in Occupational Tasks: A Manual Patient Handling Example
(University of Waterloo, 2010-12-16)Redundancy and variation are characteristics of humans. Many muscles contribute to producing a movement at a joint, allowing different strategies for task performance. Further, the shoulders and back are involved in many ... -
The Association between Fractures, Posture and Physical Performance Measures in Women Over the Age of 65
(University of Waterloo, 2016-10-06)Background Information: Vertebral fractures are a common type of osteoporotic fracture, associated with increased morbidity and mortality. An accumulation of vertebral fractures may lead to postural changes including ... -
Attention and Age-Related Components of Visual-Tactile Modulation of Somatosensory Cortex and Motor Implications
(University of Waterloo, 2010-06-16)Successful interaction with the external world requires continual sensory detection, sensorimotor translations and goal-directed motor execution. Attention to task-relevant stimulation can facilitate sensory detection and ... -
Automated Histological Analysis System for Quantifying Microstructural Damage Accumulation to the Annulus Fibrosus
(Kitchener-Waterloo Vision and Imaging Society, 2016)In this paper, we proposed an automated histological analysis system for quantifying microstructural damage accumulation to the annulus fibrosus. This system takes in a digital histology image and uses Gaussian mixture ... -
Autophagy Regulates the NOTCH Signaling Pathway During Skeletal Muscle Cell Differentiation
(University of Waterloo, 2021-06-01)Research has indicated a crucial role for autophagy during skeletal muscle differentiation. More so, the inhibition of autophagy using 3MA (3-methyladenine), CQ (chloroquine), and shRNA against Atg7 has been shown to impair ... -
