Sullivan, Lundon C. Burton, Kun Ho Kim, Yaohui Nie, Monica J. Hubal, Jonathan H. Shannahan, Shihuan Kuang, Timothy P. Gavin

Purdue University Libraries Open Access Publishing Fund

Skeletal muscle fibers regulate surrounding endothelial cells (EC) via secretion of numerous angiogenic factors, including extracellular vesicles (SkM-EV). Muscle fibers are broadly classified as oxidative (OXI) or glycolytic (GLY) depending on their metabolic characteristics. OXI fibers secrete more pro-angiogenic factors and have greater capillary densities than GLY fibers. OXI muscle secretes more EV than GLY, however it is unknown whether muscle metabolic characteristics regulate EV contents and signaling potential. EVs were isolated from primarily oxidative or glycolytic muscle tissue from mice. MicroRNA (miR) contents were determined and endothelial cells were treated with OXI- and GLY-EV to investigate angiogenic signaling potential. …

The Effects Of Acute Hyperosmolality On Immune Cell Functions And Nutrient Sensing, Joshua Granger

LSU Doctoral Dissertations

Hyperosmolar hyperglycemic syndrome (HHS) is a life-threating endocrine emergency commonly seen with type 2 diabetes. HHS has been identified to begin when hyperglycemia leads to glucosuria diuresis, which eventually leads to hyperosmotic conditions. However, hyperosmolality has not been considered as an initiator of HHS, although past research would suggest that it can initiate HHS, specifically through systemic inflammation and glucose insensitivity.

The first study examined the impact of exercise induced hypohydration effect on T-cell populations. After healthy participants reached hypohydration they were then rehydrated with water and monitored for 3-hours. Results indicated that rehydration attenuated the efflux of T-cells from …

Characterization Of Adipocyte Mechanical Properties And Stretch Control Of Mechanosignaling In Adipocytes, Tasneem Bouzid

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Obesity has reached global epidemic levels in recent decades and is the leading risk factor for type-2 diabetes (T2D). Adipose tissue behaves as a link between obesity and T2D, with dysfunctional extracellular matrix (ECM) remodeling, adipokine secretion and lipid metabolism leading to insulin resistance. The extracellular mechanophysical milieus is understood to regulate adipocyte differentiation and function through activation of mechanosensory machinery and related pathways. Therefore, exploring the adipocytic response to mechanical loading can provide great pathophysiological insight into obesity and T2D.

Adipose tissue is exposed to various compound forces due to weight-bearing and movement, and adipocyte stiffness influences stress distribution …

Exploration Of Motion Capture System To Investigate Human Shoulder Kinematics, Ola Alsaadi

Electronic Theses and Dissertations

The glenohumeral joint (GH) is commonly conceptualized as a ball-and-socket joint [1], and its center of rotation (COR) is presumed to coincide with the geometric center of the medial-superior region of the humeral head [2]. Recent research has endorsed improvements in COR estimation through invasive and noninvasive techniques, including cadaver studies, stereophotogrammetry, and motion capture (MOCAP) systems. Despite increased interest in wearable technology within human movement analysis, the problem of COR estimation employing MOCAP systems and its validation against bi-planar fluoroscopy remains relatively unexplored.

This study employed a marker-based MOCAP system to compare the accuracy, error, and precision of three …

The Acute Impacts Of Resistance Training Performed With And Without Blood Flow Restriction On Lower Body Muscular Power, Justin Faller, Brian Thompson, Stephen Ives

International Journal of Exercise Science

International Journal of Exercise Science 16(6): 1320-1333, 2023. The American College of Sports Medicine recommends resistance training using at least 70% one repetition maximum to improve muscular strength and hypertrophy; however, these intensities may not be safe for all populations. A training technique that has been reported to elicit increases in strength and muscle size uses low intensity resistance training or low load training in combination with blood flow restriction (BFR) to the working muscle. Although the acute effects of BFR on muscle strength and size are well established, the effects of BFR on muscular power are not definitively known. …
