Successful Surgical Outcome After Traumatic Diaphragmatic Intra-Pericardial Herniation From Blunt Abdominal Injury, Tyler Bayliss, Mark H. Cooper, Paul Bown

Marshall Journal of Medicine

Intrapericardial diaphragmatic hernia (IPDH) is a rare manifestation of non-hiatal diaphragmatic hernias (NHDH). Intrapericardial diaphragmatic hernia is defined as the prolapse of the abdominal viscera into the pericardium through the diaphragm. Their incidence has increased over the last 50-60 years, secondary to high-speed transport, and constitutes 5% of major thoracic and abdominal trauma today. These injuries can present during the initial workup or months after the initiating injury. These hernias can be caused by both blunt and penetrating trauma with concomitant central tendon rupture and pericardial laceration. We report an interesting case of intrapericardial diaphragmatic hernia with delayed presentation that …

Current And Novel Neuroregenerative Therapies, Arrin Brooks

Theses, Dissertations and Capstones

Underlying the physical and cognitive deficits consequent of many neuropathologies is one common factor, the loss of neurons. While neurodegenerative diseases, stroke, and traumatic brain injury arise from a variety of etiologies, they all ultimately result in injury and/or death of neuronal cells and concomitant functional deficits. In the present work we primarily focus on current and potential treatments for localized lesions, particularly those in the striatum of Parkinson’s disease (PD) or the cortex as in stroke. First, we discuss a new surgical technique for deep brain stimulator (DBS) placement, as DBS is a mainstay treatment for movement disorders including …

The Effect Of Serratus Anterior Fatigue On Scapular Kinematics, Nathan Curtis Harrison

Theses, Dissertations and Capstones

Background: Shoulder pain is a common occurrence in the general population. Pain has been associated with shoulder impairments and pathology. Associations between shoulder limitations, impairments, and mechanisms of injury and altered scapular motion appear in the literature. Fatigue of the scapular stabilizing muscles resulting from repeated arm motion has been reported to alter scapular kinematics, which could result in shoulder pathology, especially impingement.

Purpose: The purpose of this study was to examine the effects of fatigue of the serratus anterior muscle on scapular kinematics. The hypotheses were that there would be decreased posterior tilt and decreased upward rotation during arm …

Perceived Exertion And The Increase In Risk Of Injury In Rotc Cadets, Courtney D. Chiaramonte

Theses, Dissertations and Capstones

Context: Musculoskeletal injury in military personnel creates problems due to economic losses, and decreased training. The repetitive motions associated with military training and the daily physical training sessions can lead to the development of fatigue. Fatigue has been shown to contribute to 18% - 26% of musculoskeletal injuries. [7] Several studies have explored fatigue as a risk of injury during occupation. Fatigue has been shown to increase the perceived effort during physical exercise. The purpose of this study was to characterize the perception of effort during physical training sessions and injury rates in ROTC cadets throughout an academic year.

The Fit-Hansa Demonstrates Reliability And Convergent Validity Of Functional Performance In Patients With Shoulder Disorders, Prajyot Kumta, Joy C. Macdermid, Saurabh Mehta, Paul W. Stratford

Physical Therapy Faculty Research

Study

DesignPsychometric study design.

Objectives

To assess the test-retest reliability and convergent validity of the Functional Impairment Test-Hand and Neck/Shoulder/Arm (FIT-HaNSA) in patients with shoulder disorders.

Background

Performance tests that assess functional ability of patients with shoulder disorders can provide useful information for making clinical or return-to-activity decisions. No performance-based shoulder test has yet demonstrated sufficient relevance or clinical measurement properties. The FIT-HaNSA examines upper extremity performance during repetitive tasks that emphasize shoulder reaching and static postures and, therefore, has greater relevance for assessing performance.

Methods

Thirty-six patients with shoulder disorders and 65 healthy controls were recruited for the study. …

Fracture In Teeth—A Diagnostic For Inferring Bite Force And Tooth Function, Paul J. Constantino, Brian R. Lawn, James J.-W. Lee, Peter W. Lucas

Biological Sciences Faculty Research

Teeth are brittle and highly susceptible to cracking. We propose that observations of such cracking can be used as a diagnostic tool for predicting bite force and inferring tooth function in living and fossil mammals. Laboratory tests on model tooth structures and extracted human teeth in simulated biting identify the principal fracture modes in enamel. Examination of museum specimens reveals the presence of similar fractures in a wide range of vertebrates, suggesting that cracks extended during ingestion or mastication. The use of ‘fracture mechanics’ from materials engineering provides elegant relations for quantifying critical bite forces in terms of characteristic tooth …

Nanofiber Scaffolds With Gradations In Mineral Content For Mimicking The Tendon-To-Bone Insertion Site, Xiaoran Li, Jingwei Xie, Justin Lipner, Xiaoyan Yuan, Stavros Thomopoulos, Younan Xia

MIIR Faculty Research

We have demonstrated a simple and versatile method for generating a continuously graded, bonelike calcium phosphate coating on a nonwoven mat of electrospun nanofibers. A linear gradient in calcium phosphate content could be achieved across the surface of the nanofiber mat. The gradient had functional consequences with regard to stiffness and biological activity. Specifically, the gradient in mineral content resulted in a gradient in the stiffness of the scaffold and further influenced the activity of mouse preosteoblast MC3T3 cells. This new class of nanofiberbased scaffolds can potentially be employed for repairing the tendon-to-bone insertion site via a tissue engineering approach.

Control Of Myosin Motor Activity And Actin Filament Translation By Alteration Of Assay Reducing Potential, Siva Krishna Nalabotu

Theses, Dissertations and Capstones

The use of biomolecular motors for nanotechnological applications has been impaired by an inability to control biomolecular motor activity in a temporal fashion. Previous data has suggested that myosin activity can be modulated by inducing changes in the degree of myosin oxidation. The hypothesis of this study is that myosin motor activity can be regulated by altering the amount of antioxidants and reducing agents present in assay solution. To test this hypothesis we systematically altered the concentration of reducing agents and examined the effects of these changes on myosin-dependent actin filament translation. Our findings indicate that myosin activity can be …

Loss Of Ski Expression In Testicular Cancer Leads To An Enhanced Invasive Phenotype Through Both Bmp-Dependent And Bmp-Independent Pathways, Amy N. Nash

Theses, Dissertations and Capstones

The proto-oncogene SKI is a transcription factor and a co-repressor of the TGFβ superfamily, including TGF

β and BMP. However, additional data suggests that SKI may function as a tumor suppressor in some cell types. The TGFβ superfamily has been implicated in cancer progression and germ cell migration. Testicular cancer afflicts men during their peak reproductive years and is the most common cancer among men of this age group. Cisplatin-based chemotherapy is the standard treatment for testicular cancer. This treatment can lead to undesirable side effects, including infertility. We have shown that SKI expression is decreased in testicular germ cell …

Enumeration Of Endothelial Progenitor Cells In Hind Limb Suspended Rats And The Mechanics Of Endothelial Wound Healing, Jarrod Matthew Pennington

Theses, Dissertations and Capstones

The endothelium repairs itself through two methods. One is by the activity of circulating endothelial progenitor cells (EPCs). EPCs are immature endothelial cells that circulate the bloodstream that are capable of proliferation and differentiation into mature endothelium. It is thought that EPCs contribute to the repair and replacement of damaged endothelial cells in the process of reendothelialization. Physical inactivity and bed rest are known to be deleterious to the endothelium. It is possible that this inactivity is also deleterious to the number of viable EPCs, which would reduce the ability of the endothelium to repair itself. We used hind limb …

Chronic Acetaminophen Treatment Influences Indices Of Reactive Oxygen Species Accumulation In The Aging Fisher 344 X Brown Norway Rat Aorta, Sarath Meduru

Theses, Dissertations and Capstones

We have previously reported that aging in the Fisher 344 X Brown Norway (FBN) rat aorta is characterized by increased levels of ROS and alterations in cell signaling. Acetaminophen was found to scavenge free radicals in recent ischemia-reperfusion studies. Here we examined if chronic treatment with a therapeutic dose of acetaminophen attenuates age-associated increase in aortic ROS accumulation and signaling. FBN rats (27 month old; n=8) were subjected to 6 months of treatment with a therapeutic dose of acetaminophen (30mg/kg/day), with age-matched untreated FBN rats as controls. Protein oxidation levels were altered in control and treated aortae compared to aortae …

The Expression And Function Of Ppar And Hif-1 In Human Melanoma, Caroline Mills

Theses, Dissertations and Capstones

The first part of my dissertation focuses on the expression and function of PPARs in human melanoma. I found that the A375 cells were significantly growth inhibited in response to _PGJ2 and troglitazone treatment. HEMn-LP showed significant growth inhibition in response to troglitazone. I found that PPARγ and PPARδ mRNA is present in both the SK-Mel 28 and A375 cells. The relative level of PPARα mRNA expression is highest in SK-Mel 28 cells, ~3 fold higher relative to both the normal human melanocytes and A375 cells. PPARγ protein was ~50% higher in both SK-Mel 28 and A375 cells relative to …

The Zucker Rat As A Model Of Obesity-Hypertension, Ryan Morrison

Theses, Dissertations and Capstones

Hypertension is a serious health problem that affects approximately 1 in 4 American adults. Most cases are diagnosed as essential hypertension, meaning that the exact cause is unknown. In most patients, however, excess weight is a major contributory factor to the development of essential hypertension. The role of obesity in promoting hypertension is now well documented and has become the foundation for an entire field of research known alternately as obesity-hypertension, obesity-induced hypertension, or obesity-associated hypertension. In this field, rapid advances are being made in our understanding of how obesity and hypertension are linked. A plethora of related risk factors, …

Central Somatosensory Changes And Altered Muscle Synergies In Subjects With Anterior Cruciate Ligament Deficiency, Carol Courtney, Rose Marie Rine, Penny G. Kroll

Physical Therapy Faculty Research

To clarify the mechanisms of compensation in subjects with anterior cruciate ligament deficiency (ACL-D), we examined proprioception, quadriceps strength, somatosensory evoked potentials (SEPs) and muscle responses during gait in varied combinations of speed and incline. Seventeen subjects with ACL-D were grouped by functional level and report of giving way. Seven subjects without ACL-D served as a control sample for muscle response measures. ACL-D subjects with quadriceps weakness experienced giving way and could not resume sport activities. Those without weakness fell into one of two groups: (1) copers, who had full return to previous activity and no giving way despite proprioceptive …

Renal Basolateral Transport Of Glucuronides And Other Organic Anions In Rat In Vitro Models, Sarah L. Miles

Theses, Dissertations and Capstones

Glucuronidation is a common Phase II biotransformation reaction that increases the hydrophilicity, and thus elimination, of toxins, xenobiotics, and endogenous compounds. Previous studies suggest that the kidney can secrete glucuronide conjugates, but the renal transport mechanisms for glucuronide secretion have not been determined. Based on the chemical nature of glucuronide metabolites, it is hypothesized that organic anion transporter (OAT) proteins along the basolateral membrane of the renal proximal tubule promote renal accumulation of glucuronide conjugates. The purpose of this study was to develop a rat renal proximal tubule model which demonstrates OAT activity and by which the contribution of OAT …

Hk-2 Cells As A Human Model Of Glucuronide Transport, Eliza E. Robertson

Theses, Dissertations and Capstones

Glucuronidation is primarily a pathway of detoxification in most species, but many glucuronide conjugates are associated with toxicity. Numerous drugs are excreted in the urine as glucuronide conjugates. Being organic anions, it is likely that glucuronides are secreted into the urine by organic anion transporters found in renal proximal tubule cells (PTCs). Some drugs that are metabolized by glucuronidation have been shown to cause renal toxicity, yet little is known about the renal handling of glucuronide conjugates. It is hypothesized that glucuronides are transported into renal PTCs by an organic anion transporter (OAT) on the basolateral membrane of the cell. …

Detection Of Forces And Body Load In Standing And Walking In The American Cockroach, J. Adam Noah

Theses, Dissertations and Capstones

Sense organs in the legs that detect body weight are an important component in the regulation of posture and locomotion. This thesis seeks to gain an understanding of how body weight is detected by sense organs of the legs, and determine how this information influences muscle activities in standing and walking. The first study tested the ability of tibial campaniform sensilla (receptors that monitor forces in the cockroach leg) to encode variations in body load using magnets attached to the thorax. Recordings of sensory activities in freely standing animals showed that proximal tibial sensilla (oriented perpendicular to the leg long …

Comparison Of Hydrostatic Weighing And Plethysmography Techniques For The Development Of Skinfold Prediction Equations For Children, Tomoko Tozuka

Theses, Dissertations and Capstones

Regression equations between skinfold (SKF) measurements and air displacement plethysmography (ADP) were determined 6 to 18 year old athletes (80 males / 34 females) using Pearson r correlation coefficients. Triceps and mid-calf SKF and percent body fat (%BF) by ADP were measured during an Athletic Ability Assessment at The HIT Center (Huntington, WV). A high relationship was found between SKF and %BF by ADP (males; r² = .76, females; r² = .74, all; r² = .77). Data from the subjects were compared with similar correlations determined between SKF and %BF by hydrostatic weighing (HW) from another study …

The Regulation Of Manganese Superoxide Dismutase And Inducible Nitric Oxide Synthase By Nuclear Factor-Kappa B And Activator Protein 1 In Rat Aortic Endothelial Cells, Scott L. Cobbs

Theses, Dissertations and Capstones

Inducible nitric oxide synthase (iNOS) and manganese superoxide dismutase (MnSOD) are two enzymes that influence reactive oxygen species within the cell. The promoter regions for the genes encoding these enzymes have two specific transcription factor elements in common, activator protein 1 (AP-1) and nuclear factor kappa b (NF-KB). This study was initiated to determine if either NF-KB or AP-1 regulates the transcription of both genes in endothelial cells. To test whether NF-KB or AP-1 binding sites in the MnSOD and iNOS promoter region were important for transcriptional regulation, we performed induction analysis using various deletion constructs of MnSOD and iNOS …
