Characterization of the Human Plasma Macrolipidome using Standard Reference Material 1950 - Metabolites in frozen human plasma
(University of Waterloo, 2022-01-26)Standard Reference Material (SRM) 1950 Metabolites in frozen human plasma is a pooled plasma sample created by the National Institute of Standards and Technology (NIST) to be representative of plasma from the population ... -
Characterizing a Novel Enzyme Involved in Cardiolipin Remodelling
(University of Waterloo, 2023-12-05)Background: Cardiolipin (CL) is a specialized dimeric phospholipid comprising approximately 25% of total phospholipids in the inner mitochondrial membrane in eukaryotes, where it functions in energy metabolism, autophagy ... -
Characterizing Sex Differences in Lipid Metabolism during an Acute, 30-Minute Bout of Moderate- Intensity Continuous (MIC) Exercise
(University of Waterloo, 2021-01-05)INTRODUCTION: Increased intramyocellular lipid (IMCL) size and storage in the subsarcolemmal region of the myocyte are associated with insulin resistance (IR) and the development of type 2 diabetes (T2D). Women have a ... -
Characterizing Sex Differences in Skeletal Muscle Anaerobic Metabolism during an Acute Bout of High Intensity Interval Exercise
(University of Waterloo, 2020-09-03)INTRODUCTION: Exercise is known to improve insulin sensitivity (IS); however, its effectiveness may be absent or blunted in women, particularly following high intensity interval (HII) training. Sex differences in anaerobic ... -
Characterizing site-specific body composition of older adults and their associations with strength, functional capacity, and metabolic health
(University of Waterloo, 2021-06-03)Background: Ageing is associated with skeletal muscle atrophy and increased intramuscular adipose tissue. Emerging evidence indicates that specific muscle groups may be largely responsible for the ageing-related degradation ... -
Characterizing the Biomechanical Exposures Associated with Common and High Demand Personal Support Worker Tasks
(University of Waterloo, 2023-08-31)Background: The physical demands that personal support workers (PSWs) are exposed to are increasing as our population ages and our society is increasingly shifting to at-home care, resulting in increases in workload ... -
Characterizing the dynamics of vestibular reflex gain modulation using balance-relevant sensory conflict
(University of Waterloo, 2023-09-21)Electrical vestibular stimulation (EVS) can be used to evoke reflexive body sways as a probe of vestibular control of balance. However, EVS introduces sensory conflict by decoupling vestibular input from actual body motion, ... -
Characterizing the Role of Phospholamban in Duchenne Muscular Dystrophy
(University of Waterloo, 2018-01-16)Duchenne muscular dystrophy (DMD) and the murine model, mdx, are recessive X-linked myopathies characterized by aberrant Ca2+-handling resulting in muscle atrophy and weakness. Phospholamban (PLN) is a protein inhibitor ... -
Characterizing the Roles of Myoregulin and Dwarf Open Reading Frame in Regulating Calcium Homeostasis in Muscle
(University of Waterloo, 2024-01-26)The sarco(endo)plasmic reticulum Ca2+-ATPases (SERCAs) are responsible for inducing muscle relaxation and are integral to the maintenance of intracellular calcium (Ca2+) homeostasis. As such, their activity is modulated ... -
Characterizing the Variability of Kinematic Outcome Measures and Compensatory Movements using Inertial Measurement Units
(University of Waterloo, 2019-01-22)Cost-effective wearable sensors to measure movement have gained traction as research and clinical tools. The potential to quantify movement with a portable and inexpensive way could provide benefits to patient populations ... -
Clinical assessment of body composition after spinal cord injury. An observational study.
(University of Waterloo, 2009-11-19)Background: Persons who sustain a spinal cord injury (SCI) experience a dramatic loss of muscle and bone, and a dramatic increase in adipose tissue. It has been suggested that the muscle atrophy, obesity, and sublesional ... -
Coded Hemodynamic Imaging of the Jugular Vein and Ultrasound Imaging of the Optic Nerve Sheath Diameter during Manipulations of Intracranial Pressure by Head-Down Tilt
(University of Waterloo, 2020-08-21)Background: Spaceflight associated neuro-ocular syndrome (SANS) is a condition in which worsening vision occurs while in microgravity. It has been hypothesized that SANS is caused by an increase in intracranial pressure ... -
Cognitive control, conflict monitoring, and aerobic exercise.
(University of Waterloo, 2018-05-01)Cognitive control includes a subset of top-down cognitive functions that allow flexible goal-directed behaviour that are often impaired in people with mental illness and in older adults. Even in healthy individuals, cognitive ... -
Combined cognitive and exercise training for community-dwelling adults and older adults: A feasibility study
(University of Waterloo, 2020-08-31)Older adults show cognitive improvements after taking part in exercise training or cognitive training. A number of studies suggest that combining these two types of interventions may lead to greater cognitive gains. However, ... -
A combined in vivo and in vitro approach to assess supraspinatus activation and tissue responses to arm elevation demands
(University of Waterloo, 2020-01-22)Rotator cuff degeneration affects a large portion of the human population, yet knowledge surrounding which loading scenarios allow transition from healthy to diseased states remains largely unresolved. Mechanistic progression ... -
Comparing functional dynamic normalization methods to maximal voluntary isometric contractions for lower limb EMG from walking, cycling and running
(Elsevier, 2019-02)There is no consensus on the most appropriate method for normalizing an individual’s electromyography (EMG) signals from walking, cycling and running in the same data collection. The aim of this study was to compare how ... -
Comparing knee joint kinematics, kinetics and cumulative load between healthy-weight and obese young adults
(University of Waterloo, 2011-05-20)One of the most poorly understood co-morbidities associated with obesity is the pathway to osteoarthritis of the knee. To implement appropriate preventative strategies, it is important to explore how obesity is a causal ... -
Comparing occupational musculoskeletal exposures during common materials handling tasks between non-obese and obese adults
