The Effect Of Arch Height On Variances In Gait Phases: A Kinematic Analysis, 2019 University of Northern Iowa
The Effect Of Arch Height On Variances In Gait Phases: A Kinematic Analysis, Mackenzie J. Haag
Honors Program Theses
Millions of individuals suffer from pain or injury as a result of structural abnormalities of the medial longitudinal arch of the foot and/or improper footwear. A majority of the research on abnormalities of the medial longitudinal arch is focused on how the arch alters foot kinematics during gait but does not ask how abnormalities may contribute to deviations in knee kinematics as well. The purpose of this study was to determine the effect of foot arch types on deviations in healthy biomechanical gait in addition to the implications of orthotics in order to ultimately aid in the decrease of ...

Developmental Dependence For Functional Eye Regrowth In Xenopus Laevis, 2018 University of Nevada, Las Vegas
Developmental Dependence For Functional Eye Regrowth In Xenopus Laevis, Cindy X. Kha, Kelly Ai-Sun Tseng
Life Sciences Faculty Publications
A key challenge in designing tissue repair strategies is knowing whether and how developmental mechanisms are used for successful repair of mature/adult tissues. Although it is known that developmental components are used in repair, it remains mostly unclear which ones are required and whether they act similarly as during development. This issue is further complicated by the fact that it is difficult to assess the similarities and differences between development and the repair of mature tissues, since the two contexts are highly dissimilar. A potentially useful yet underutilized approach is to understand developmental regrowth (defined here as the ability ...

Modulation Of Parathyroid Hormone 1 Receptor Signaling By Extracellular Nucleotides, 2018 The University of Western Ontario
Modulation Of Parathyroid Hormone 1 Receptor Signaling By Extracellular Nucleotides, Brandon Kim
Electronic Thesis and Dissertation Repository
Parathyroid hormone (PTH) activates the PTH/PTH-related peptide receptor (PTH1R) on osteoblasts and other target cells. Mechanical stimulation of cells, including osteoblasts, causes release of nucleotides such as ATP into the extracellular fluid. In addition to its role as an energy source, ATP serves as an agonist at P2 receptors and an allosteric regulator of many proteins. We investigated the effects of concentrations of extracellular ATP, comparable to those that activate low affinity P2X7 receptors, on PTH1R signaling. Cyclic AMP levels were monitored in real-time using a bioluminescence reporter and β-arrestin recruitment to PTH1R was followed using a complementation-based luminescence ...

Kristen L. McHenry
Interprofessional education has the potential to prepare health career students to be practice-ready and enter the workforce with a collaborative mindset. Respiratory care educators must adequately prepare students to work in this capacity. This emphasis on a team approach to patient-centered care has the ability to impact and improve health outcomes. Throughout the last decade, sleep medicine has experienced fluctuations. Sustainability of sleep labs who only perform diagnostic testing may prove challenging. The role of interprofessional practice in sleep medicine would be to overcome traditional roles (silos) so that multiple skilled practitioners could help identify and treat complex patient conditions ...
Physiological Differences Between Low Versus High Skeletal Muscle Hypertrophic Responders To Resistance Exercise Training: Current Perspectives And Future Research Directions, Michael D. Roberts, Cody T. Haun, Christopher B. Mobley, Petey W. Mumford, Matthew A. Romero, Paul A. Roberson, Christopher G. Vann, John J. Mccarthy
Physiology Faculty Publications
Numerous reports suggest there are low and high skeletal muscle hypertrophic responders following weeks to months of structured resistance exercise training (referred to as low and high responders herein). Specifically, divergent alterations in muscle fiber cross sectional area (fCSA), vastus lateralis thickness, and whole body lean tissue mass have been shown to occur in high versus low responders. Differential responses in ribosome biogenesis and subsequent protein synthetic rates during training seemingly explain some of this individual variation in humans, and mechanistic in vitro and rodent studies provide further evidence that ribosome biogenesis is critical for muscle hypertrophy. High responders may ...

Spinal Cord Trauma: An Overview Of Normal Structure And Function, Primary And Secondary Mechanisms Of Injury, And Emerging Treatment Modalities, Daniel Morin
Senior Honors Theses
The structures of the spinal cord and vertebral column are designed to provide flexibility, while still providing ample protection for the spinal cord deep within. While it does offer remarkable protection against most routine trauma, the spinal cord is still vulnerable to high-force etiologies of trauma and may become damaged as a result. These events are referred to as primary injury. Following the initial injury, the body’s own physiological responses cause a cascade of deleterious effects, known as secondary injury. Secondary injury is a major therapeutic target in mitigating the effects of spinal cord injury (SCI), and much research ...

Objective: Limited attention has been given to ocular injuries associated with traumatic brain injury (TBI). The retina is an extension of the central nervous system and evaluation of ocular damage may offer a less-invasive approach to gauge TBI severity and response to treatment. We aim to characterize acute changes in the mouse eye after exposure to two different models of TBI to assess the utility of eye damage as a surrogate to brain injury.
Methods: A model of blast TBI (bTBI) using a shock tube was compared to a lateral fluid percussion injury model (LFPI) using fluid pressure applied directly ...

The Effects Of Emerging Technology On Healthcare And The Difficulties Of Integration, 2018 University of Central Florida
The Effects Of Emerging Technology On Healthcare And The Difficulties Of Integration, Skyler J. Pavlish-Carpenter
Honors Undergraduate Theses
Background: Disruptive technology describes technology that is significantly more advanced than previous iterations, such as: 3D printing, genetic manipulation, stem cell research, innovative surgical procedures, and computer-based charting software. These technologies often require extensive overhauls to implement into older systems and must overcome many difficult financial and societal complications before they can be widely used. In a field like healthcare that makes frequent advancements, these difficulties can mean that the technology will not be utilized to its full potential or implemented at all.
Objective: To determine the inhibiting factors that prevent disruptive technology from being implemented in conventional healthcare.
