Human Movement Studies & Special Education Theses & Dissertations

Ankle taping is a common practice in the athletic training room, but there is minimal evidence to support its effectiveness in enhancing muscle activation. The purpose of this study was to examine the effects of ankle taping on muscle activation following sudden inversion in functionally unstable and healthy ankles before and after exercise. Fourteen recreational athletes with a unilateral functionally unstable ankle volunteered to participate. Surface EMG electrodes were placed on the peroneals and anterior tibialis muscles of both extremities. Each subject received four treatment conditions; ankle taping, ankle taping with spatting, spatting, and no tape in a randomly assigned, …


Qtc Is Associated With Obesity And Physical Activity Level For African American Females, C. Jayne Brahler Apr 2004

Qtc Is Associated With Obesity And Physical Activity Level For African American Females, C. Jayne Brahler

Health and Sport Science Faculty Publications

Long QT syndrome (LQTS) is an independent risk factor for cardiovascular or ischemic disease mortality. Obesity as a cause for acquired LQTS in otherwise healthy individuals is rapidly gaining the attention of the scientific community. African American people have a higher incidence of obesity compared to Caucasians, yet race-specific information is not available for their prevalence of LQTS. Chronic physical activity can help reduce the incidence of obesity, yet little is known about the effects of chronic physical activity on acquired LQTS. Subjects in this study were a volunteer sample of African American mothers (21-53 yr, n = 44) and …

Hk-2 Cells As A Human Model Of Glucuronide Transport, Eliza E. Robertson Jan 2004

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. …

Renal Basolateral Transport Of Glucuronides And Other Organic Anions In Rat In Vitro Models, Sarah L. Miles Jan 2004

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 …

A bolus 1-mg dose of CyA was injected into the inlet catheter and periodical samples (0-15 min) were collected from the outlet perfusate. The concentrations of CyA in the outlet perfusate, collected bile (0-15 min), and liver tissue (at the end of perfusion) were quantitated by HPLC and subjected to statistical moment analysis. …


Deep Muscle Function In The Cervical Spine: Application To Musculoskeletal Modelling, Jonathon Green Jan 2004

Deep Muscle Function In The Cervical Spine: Application To Musculoskeletal Modelling, Jonathon Green

Theses : Honours

Neck pain in occupational tasks is a problem that involves a high cost to society therefore, understanding the mechanics of musculoskeletal loading is important in formulating preventative rehabilitation strategies. Musculoskeletal modelling of the neck provides a means by which to calculate loads on the components and muscles of the neck thus allowing quantitative data to be gained non-invasivcly for a wide range of occupational tasks. Anatomically detailed, electromyography (EMG) driven neck models require deep muscle EMG activation profiles which arc difficult to attain without invasive EMG procedures. The aim of this study was to determine whether EMG activity of semispinalis …


A Body Of Her Own: Cultural Constructions Of The Female Body In A.S. Byatt's Strange Stories, Sabine Coelsch-Foisner Oct 2003

A Body Of Her Own: Cultural Constructions Of The Female Body In A.S. Byatt's Strange Stories, Sabine Coelsch-Foisner

Reconstruction: Studies in Contemporary Culture

[First paragraph]

Byatt's short fiction, from her first collection Sugar and Other Stories (1987) to Elementals (1998) is marked by a continuous preoccupation with the body: the body as the product of social signifying practices, the body as the site of desires, fears, and anxieties, the body as the source of experience, the body as creator and created. In brief, the body is treated as the centre of existence, consciousness and identity. Yet, these are constantly called into doubt in Byatt's stories, which depict heroines trapped between asserting their identity and submitting to cultural dictates of beauty and behavior. In …


Immortalized Epithelial Cells From Human Autosomal Dominant Polycystic Kidney Cysts, Mahmoud Loghman-Adham, Surya M. Nauli, Carlos E. Soto, Barbara Kariuki, Jing Zhou Sep 2003

Immortalized Epithelial Cells From Human Autosomal Dominant Polycystic Kidney Cysts, Mahmoud Loghman-Adham, Surya M. Nauli, Carlos E. Soto, Barbara Kariuki, Jing Zhou

Pharmacy Faculty Articles and Research

Autosomal dominant polycystic kidney disease (ADPKD) is the result of mutations in one allele of the PKD1 or PKD2 genes, followed by "second hit" somatic mutations of the other allele in renal tubule cells. Continued proliferation of clonal cells originating from different nephron segments leads to cyst formation. In vitro studies of the mechanisms of cyst formation have been hampered by the scarcity of nephrectomy specimens and the limited life span of cyst-derived cells in primary culture. We describe the development of a series of immortalized epithelial cell lines from over 30 individual renal cysts obtained from 11 patients with …


Radiation Effects On Dopamine-Mediated Prepulse Inhibition In The C57bl/6 Mouse, Cara Nicole Zuccarelli Miller Sep 2003

Radiation Effects On Dopamine-Mediated Prepulse Inhibition In The C57bl/6 Mouse, Cara Nicole Zuccarelli Miller

Loma Linda University Electronic Theses, Dissertations & Projects

This study examined the effects of proton and gamma radiation on a dopamine-dependent sensory gating mechanism: prepulse inhibition of the startle reflex. The purpose of this research was to describe potential hazards of proton radiation to the central nervous system in long-term space fight and for proton therapy patients. Results from previous research indicate that startle behavior is modified by proton and iron radiation. Forty-eight 10-½ week old, male C57BL/6 mice were used to characterize the optimal parameters for the model (prepulse duration, probe duration, and stimulus-onset-asynchrony). Three hundred and fifty two mice were used to characterize the time course …


Magnetic Resonance Images Of The Brain Of A Dwarf Sperm Whale (Kogia Simus), L. Marino, K. Sudheimer, D. A. Pabst, J. I. Johnson Jul 2003

Magnetic Resonance Images Of The Brain Of A Dwarf Sperm Whale (Kogia Simus), L. Marino, K. Sudheimer, D. A. Pabst, J. I. Johnson

Veterinary Science and Medicine Collection

Cetacean (dolphin, whale and porpoise) brains are among the least studied mammalian brains because of the difficulty of collecting and histologically preparing such relatively rare and large specimens. Among cetaceans, there exist relatively few studies of the brain of the dwarf sperm whale (Kogia simus). Magnetic resonance imaging (MRI) offers a means of observing the internal structure of the brain when traditional histological procedures are not practical. Therefore, MRI has become a critical tool in the study of the brain of cetaceans and other large species. This paper represents the first MRI-based anatomically labelled three-dimensional description of the dwarf sperm …

Hybridization Between The Watersnakes Nerodia Sipedon And Nerodia Fasciata, In The Carolinas: A Morphological And Molecular Approach, Konrad Mebert Apr 2003

Hybridization Between The Watersnakes Nerodia Sipedon And Nerodia Fasciata, In The Carolinas: A Morphological And Molecular Approach, Konrad Mebert

Biological Sciences Theses & Dissertations

A few traditionally applied diagnostic characters of color pattern were compared with an additional set of morphological and genetic characters to evaluate differences between Nerodia sipedon and N. fasciata and to study the dynamics across their hybrid zone in the Carolinas. Many of the morphological characters exhibited significant interspecific differences, although only the number of dorsally complete crossbands (CBa) was diagnostic by itself. A discriminant function analysis of morphological characters was successful in separating both taxa. Species-specific nuclear markers, identified by the AFLP (Amplified Fragment Length Polymorphism) technique were nearly fixed and served as diagnostic markers. They revealed extensive introgression …

The purpose of this study was to examine the short-term effects of Grades 1 and 2 posteroanterior joint mobilizations (JM) at the pathological lumbar spine on subject pain, range of motion (ROM), and muscle force. All subjects were determined to have sustained mechanical dysfunction of the lumbar spine of less than 48 hours as assessed through a standardized evaluation. Subjects were randomly assigned to a group; the control group received ice and stretching while the experimental group received JM in addition to ice and stretching. The JM's were performed at 3 consecutive lumbar segments surrounding the area of greatest discomfort. …


Detection Of Forces And Body Load In Standing And Walking In The American Cockroach, J. Adam Noah Jan 2003

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 …


Oxygen Saturation Among Newborn Infants And The Decrease Occurring During Feeding In Various Populations, Jennifer Lynn Allison Jan 2003

Oxygen Saturation Among Newborn Infants And The Decrease Occurring During Feeding In Various Populations, Jennifer Lynn Allison

MUSC Theses and Dissertations

Pharyngeal and laryngeal structural movements coordinate respiration and swallowing functions, hence eliminating simultaneous execution. This research aims to document levels of oxygen saturation during rest and feeding among various newborn populations. Hypothesized is that an increase in oxygen alterations during feeding will be exhibited by infants of younger gestational age and, further, by those with the presence of respiratory anomalies. Thirty newborns in the nurseries at Medical University of South Carolina, free of cardiac and genetic maladies, were divided into three groups. Subjects of group 1 are healthy, full-term newborns; within groups 2 and 3, preterm infants (gestation). Subjects of …


Platelets Stimulate Fibroblast-Mediated Contraction Of Collagen Gels, Ulrika Zagai, Karin Fredriksson, Stephen I. Rennard, Joachim Lundahl, C. Magnus Sköld Jan 2003

Platelets Stimulate Fibroblast-Mediated Contraction Of Collagen Gels, Ulrika Zagai, Karin Fredriksson, Stephen I. Rennard, Joachim Lundahl, C. Magnus Sköld

Journal Articles: Pulmonary & Critical Care Med

BACKGROUND: Platelets are thought to play a role in a variety of inflammatory conditions in the lung, some of which may lead to fibrosis. In the current study we tested the hypothesis that whole platelets and platelet lysate can mediate remodelling of extracellular matrix in vitro by affecting fibroblast-mediated contraction of a collagen gel. We also sought to determine to what extent platelet-derived growth factor (PDGF) and transforming growth factor-beta (TGF-beta) contribute to this effect.

METHODS: Washed platelets, isolated from healthy blood donors, and platelet lysate (freezing and thawing), were cast together with human lung fibroblasts in three-dimensional collagen gels. …


Human Cytomegalovirus Chemokine Receptor Us28-Induced Smooth Muscle Cell Migration Is Mediated By Focal Adhesion Kinase And Src, Daniel N. Streblow, Jennifer Totonchy, Patsy Smith, Ryan Melnychuk, Laurel Hall, Dora Pancheva, Martine Smit, Paola Casarosa, David D. Schlaepfer, Jay A. Nelson Jan 2003

Human Cytomegalovirus Chemokine Receptor Us28-Induced Smooth Muscle Cell Migration Is Mediated By Focal Adhesion Kinase And Src, Daniel N. Streblow, Jennifer Totonchy, Patsy Smith, Ryan Melnychuk, Laurel Hall, Dora Pancheva, Martine Smit, Paola Casarosa, David D. Schlaepfer, Jay A. Nelson

Pharmacy Faculty Articles and Research

The human cytomegalovirus-encoded chemokine receptor US28 induces arterial smooth muscle cell (SMC) migration; however, the underlying mechanisms involved in this process are unclear. We have previously shown that US28-mediated SMC migration occurs by a ligand-dependent process that is sensitive to proteintyrosine kinase inhibitors. We demonstrate here that US28 signals through the non-receptor protein-tyrosine kinases Src and focal adhesion kinase (FAK) and that this activity is necessary for US28-mediated SMC migration. In the presence of RANTES (regulated on activation normal T cell expressed and secreted), US28 stimulates the production of a FAK Src kinase complex. Interestingly, Src co-immunoprecipitates with US28 in …


Mechanisms Underlying Protection Against Rt-2 Gliomagenesis In Rat Brain Utilizing Primary And Secondary Vaccination, Andrea M. Lister Jan 2003

Mechanisms Underlying Protection Against Rt-2 Gliomagenesis In Rat Brain Utilizing Primary And Secondary Vaccination, Andrea M. Lister

Theses and Dissertations

Primary brain tumor affects some 18,000 adults in the United States each year (Silverberg et al., 1990; Merchant et al., 1997) and over 30% are high-grade anaplastic astrocytoma or glioblastoma multiforme (GBM) (Parney et al., 1997). According to Kruse et al., 1989, the treatment of patients with recurrent or persistent high-grade gliomas represents a major therapeutic challenge. The use of conventional therapy consisting of surgery, followed by radiation therapy and chemotherapy for gliomas, has been relatively ineffective (Jaecle et al., 1994) despite the fact that these therapies are cytoreductive in nature (Black, 1991). Most malignancies will recur locally but may …


The Influence Of Slow Calcium-Activated Potassium Channels On Epileptiform Activity In A Neuronal Model Of Pyramidal Cells, Keun-Hang Susan Yang, Piotr J. Franaszczuk, Gregory K. Bergey Jan 2003

The Influence Of Slow Calcium-Activated Potassium Channels On Epileptiform Activity In A Neuronal Model Of Pyramidal Cells, Keun-Hang Susan Yang, Piotr J. Franaszczuk, Gregory K. Bergey

Mathematics, Physics, and Computer Science Faculty Articles and Research

An imbalance between excitation and inhibition can play an important role in the generation of epileptiform activity. Experimental evidence indicates that alterations of either synaptic activity or intrinsic membrane properties may contribute to this imbalance. The slow Ca2+ - activated K+ currents (sIAHP) limit neuronal firing rate and excitability and are therefore of great interest for their potential role in epileptogenesis. The sIAHP is found in both excitatory and inhibitory neurons, and its effect on these neurons can influence the network behavior. Simulations show that the increased excitability caused by reduction of inhibition by the sIAHP for inhibitory interneuron generates …

Individual, Temporal, And Seasonal Variation In Sperm Concentration In Tree Swallows, Michael P. Lombardo, Armetris N. Forman, Matthew R. Czarnowski, Patrick A. Thorpe

Peer Reviewed Publications

We determined sperm concentrations in Tree Swallows (Tachycineta bicolor) by manually expressing semen samples from males during prelaying, egg-laying, incubation, and nestling periods. Sperm concentrations varied by orders of magnitude (0-109 sperm mL-1) among males. Sperm concentrations were highest during the incubation period and lowest during the prelaying period. None of the samples collected during the prelaying, egg-laying, and incubation periods were devoid of sperm. In contrast, 45% of samples collected during the nestling period lacked sperm. Sperm concentrations (1) did not vary over the course of the morning during prelaying, egg-laying, and incubation periods …


Endocytic Intermediates Involved With The Intracellular Trafficking Of A Fluorescent Cellular Prion Protein, Ac Magalhaes, Ja Silva, Vr Martins, Vf Prado, Ssg Ferguson, Mv Gomez, Rr Brentani, Mam Prado Sep 2002

Endocytic Intermediates Involved With The Intracellular Trafficking Of A Fluorescent Cellular Prion Protein, Ac Magalhaes, Ja Silva, Vr Martins, Vf Prado, Ssg Ferguson, Mv Gomez, Rr Brentani, Mam Prado

Anatomy and Cell Biology Publications

We have investigated the intracellular traffic of PrPc, a glycosylphosphatidylinositol (GPI)-anchored protein implicated in spongiform encephalopathies. A fluorescent functional green fluorescent protein (GFP)-tagged version of PrPc is found at the cell surface and in intracellular compartments in SN56 cells. Confocal microscopy and organelle-specific markers suggest that the protein is found in both the Golgi and the recycling endosomal compartment. Perturbation of endocytosis with a dynamin I-K44A dominant-negative mutant altered the steady-state distribution of the GFP-PrPc, leading to the accumulation of fluorescence in unfissioned endocytic intermediates. These pre-endocytic intermediates did not seem to accumulate GFP-GPI, a minimum GPI-anchored protein, suggesting that …

Synthesis And Characterization Of Hydroxyapatite-Collagen Biocomposite Materials, Vuk Uskoković, Nenad Ignjatović, Nadejda Petranović

Pharmacy Faculty Articles and Research

Hydroxyapatite-collagen composite is a prosperous biomaterial in reconstructive surgery for the reparation of defects within human hard tissue. Within this research, three-dimensional blocks of HAp/collagen composite biomaterial were synthesized by homogenizing the HAp/collagen mixture by cold and hot (T=60oC) pressing (P=49 MPa). The changes in the system were followed by using thermal analysis (DSC & TGA), FT-IR spectroscopy and scanning electron microscopy (SEM). The identification and kinetic analysis of appearing phase transition were done. FT-IR spectrum of the biocomposite shows that neither cold nor hot pressing had significant influence on the individual components of the composite. SEM of the fracture …


Kalirin Dbl-Homology Guanine Nucleotide Exchange Factor 1 Domain Initiates New Axon Outgrowths Via Rhog-Mediated Mechanisms, Victor May, Martin R. Schiller, Betty A. Eipper, Richard E. Mains Aug 2002

Kalirin Dbl-Homology Guanine Nucleotide Exchange Factor 1 Domain Initiates New Axon Outgrowths Via Rhog-Mediated Mechanisms, Victor May, Martin R. Schiller, Betty A. Eipper, Richard E. Mains

Life Sciences Faculty Research

The large multidomain Kalirin and Trio proteins containing dual Rho GTPase guanine nucleotide exchange factor (GEF) domains have been implicated in the regulation of neuronal fiber extension and pathfinding during evelopment. In mammals, Kalirin is expressed predominantly in the nervous system, whereas Trio, broadly expressed throughout the body, is expressed at a lower level in the nervous system. To evaluate the role of Kalirin in fiber initiation and outgrowth, we microinjected cultured sympathetic neurons with vectors encoding Kalirin or with Kalirin antisense oligonucleotides, and we assessed neuronal fiber growth in a serum-free, satellite cell-free environment. Kalirin antisense oligonucleotides blocked the …
