The Effect Of Maté On Enzymes Involved In The Recovery From Oxidative Stress, Amina Sadik, Theodore Chang

College of Osteopathic Medicine (TUN) Publications and Research

In comparing the effect of Maté to that of green tea, it has been shown that Maté has higher anti-oxidative properties. We have shown that the extract of Yerba Maté, paraguariensis, leaves does indeed have strong anti-oxidative properties through the evaluation of its scavenging activity and its ability of assist cardiomyocytes in their recovery from induced oxidative stress using both spectroscopy, a colorimetric assay and flow cytometry. In order to elucidate the mechanism behind this action, we quantified the enzymes known to be expressed naturally by cells under oxidative stress such as glutathione peroxidase, superoxide dismutase, and catalase. These enzymes …

Scanned Ion Beam Therapy For Thoracic Tumors, John Gordon Eley

Dissertations and Theses (Open Access)

Although frequently cured of Hodgkin lymphoma, adolescents and young adults can develop radiation induced second cancers. These patients could potentially benefit from scanned ion radiotherapy yet likely would require motion mitigation strategies. In theory, four-dimensional (4D) optimization of ion beam fields for individual motion states of respiration can enable superior sparing of healthy tissue near moving targets, compared to other motion mitigation strategies. Furthermore, carbon-ion therapy can sometimes provide greater relative biological effectiveness (RBE) for cell sterilization in a target but nearly equivalent RBE in tissue upstream of the target, compared to proton therapy. Thus, we expected that for some …

A Multidisciplinary Approach To The Prevention Of Infant Torticollis And Plagiocephaly, Anne H. Zachry, S. K. Slaughter

Faculty Presentations

Research suggests that parents are more likely to carry out positioning recommendations from a health care professional than any other source. Occupational therapy practitioners can play an important role in educating parents, caregivers, and healthcare providers about the importance of providing tummy time and limiting infant time spent in baby gear.

Oncology Section Task Force On Breast Cancer Outcomes: An Introduction To The Edge Task Force And Clinical Measures Of Upper Extremity Function, Pamela K. Levangie, Mary Insana Fisher

Physical Therapy Faculty Publications

With the proliferation of outcome measures in the literature, many of which lack documentation of sufficient psychometric properties to justify use, it is difficult to document patient change or demonstrate effectiveness of interventions. The goal of the Section on Research’s EDGE (Evaluation Database to Guide Effectiveness) Task Force is to facilitate identification of valid and reliable tests and measures that reflect clinically important outcomes and are responsive to change for standard use across selected patient groups. This paper lays the groundwork for understanding the work of the Oncology Section’s Breast Cancer EDGE Task Force on clinical measures of shoulder function …

Oncology Section Task Force On Breast Cancer Outcomes: Scapular Assessment, Mary Insana Fisher, Pamela K. Levangie

Physical Therapy Faculty Publications

Background: Functional deficits and changes in scapular mechanics following breast cancer (BC) treatments have been documented. Scapular assessment is important when examining the shoulder in survivors of breast cancer to document the need for or effectiveness of physical therapy intervention. The Oncology Section Task Force on Breast Cancer Outcomes sought to identify scapular examination tools that can be recommended for routine use in individuals treated for BC.

Methods: A systematic review of the literature on scapular measures was conducted. Relevant studies were examined for psychometric properties and clinical usefulness. Each method was given a recommendation score based on the Breast …

In Vitro Manual Therapy And Biorobotic Simulation Of Glenohumeral Joint Mobilization Techniques, Hunter Johnson Smith

Theses and Dissertations (ETD)

Physical therapists (PT) employ mobilization techniques for restoring range of motion to joints. Few studies have attempted to quantify the biomechanics of manual therapy on the glenohumeral (GH) joint. The objectives of this study were to develop an in vitro protocol to determine the biomechanical effects of joint mobilization on the GH joint, and to then simulate these mobilizations in the University of Tennessee Health Science Center (UTHSC) Joint Implant Biomechanics Laboratory’s Robotic Testing Platform (RTP).

The GH joint is an incredibly shallow socket joint. This gives the joint an unusually large range of motion (ROM) compared to other ball …

Development Of Hif-1Α/Hif-1Β Heterodimerization Inhibitors Using A Novel Bioluminescence Reporter Assay System For In Vitro High Throughput Screening And In Vivo Imaging, Yun-Chen Chiang

Dissertations and Theses (Open Access)

Tumor growth often outpaces its vascularization, leading to development of a hypoxic tumor microenvironment. In response, an intracellular hypoxia survival pathway is initiated by heterodimerization of hypoxia-inducible factor (HIF)-1α and HIF-1β, which subsequently upregulates the expression of several hypoxia-inducible genes, promotes cell survival and stimulates angiogenesis in the oxygen-deprived environment. Hypoxic tumor regions are often associated with resistance to various classes of radio- or chemotherapeutic agents. Therefore, development of HIF-1α/β heterodimerization inhibitors may provide a novel approach to anti-cancer therapy. To this end, a novel approach for imaging HIF-1α/β heterodimerization in vitro and in vivo was developed in this study …

Treatment Of Psychiatric Inpatients With Relationship Dysfunction Using A Short Term Cognitive Interpersonal Intervention: A Pilot Study, Tamra Rasberry

Doctoral Dissertations and Projects

Relationship conflict for the psychiatric patient can have significant detrimental effects. There are specific types of interactions that can increase conflict and predict the potential for relapse; these have been identified by research and designated as components of Expressed Emotion (EE). Cognitive Behavioral Therapy (CBT) and Interpersonal Therapy (IPT) have been very effective when targeting specific psychiatric diagnoses, but less effective when addressing relationship conflict. The majority of studies addressing relationship conflict have taken place in an outpatient, long-term setting. There is limited research that utilizes an inpatient short-term intensive therapy with relationship conflict as its sole focus, targeting areas …

Evaluation Of The Anterior Talofibular And Calcaneofibular Ligament In Relation To Supination Ankle Sprains, Peter Tran

Biomedical Engineering

Ankle injuries have always posed an issue to a number of athletes. Sports that involve running and jumping accumulate about 25% of injuries correlating to ankle sprains. In most ankle sprains the inversion (supination) of the ankle cause damage to lateral ligaments. The two most common lateral ligaments to experience damage are the anterior talofibular (ATFL) and calcaneofibular (CFL) ligaments. The methods of taping and ankle braces have allowed athletes to prevent recurring sprains from occurring. However, sprains can still occur even when one or both methods are applied. The purpose of each method is to restrict the range of …

The Relationship Between Vitamin D Status Of Adult Women And Diet, Sun Exposure, Skin Reflectance, Body Composition, And Insulin Sensitivity, Marisa M. Mcadler

Master's Theses

As the prevalence of vitamin D deficiency continues to grow, mounting evidence supporting its link with chronic disease strengthens suggesting vitamin D’s candidacy in the prevention and treatment of multiple disease states and their complications. Dietary guidelines, however, do not take sun exposure into account. The present study sought to explore the impact of sun exposure on vitamin D status (serum 25(OH)D), and identify other significant determinants of serum levels which may have the greatest effects on overall health. Participants (n = 34) were pre-menopausal women aged 18 to 50 years (mean age 39 ± 6 years), who had their …

Sources Of Intravascular Atp During Exercise In Humans: Critical Role For Skeletal Muscle Perfusion, Brett S. Kirby, Anne R. Crecelius, Jennifer C. Richards, Frank A. Dinenno

Health and Sport Science Faculty Publications

Exercise hyperemia is regulated by several factors and one factor known to increase with exercise that evokes powerful vasomotor action is extracellular ATP. The origination of ATP detectable in plasma from exercising muscle of humans is, however, a matter of debate and ATP has been suggested to arise from sympathetic nerves, blood sources (e.g. erythrocytes), endothelial cells, and skeletal myocytes, among others. Therefore, we tested the hypothesis that acute augmentation of sympathetic nervous system activity (SNA) results in elevated plasma ATP draining skeletal muscle, and that SNA superimposition during exercise further increases ATP vs exercise alone. We show that increased …

Oxidative Stress Based Strategies For Enhancing The Efficacy Of Histone Deacetylase Inhibitors (Hdaci), Nilsa Rivera-Del Valle

Dissertations and Theses (Open Access)

Histone deacetylase inhibitors (HDACi) are anti-cancer drugs that primarily act upon acetylation of histones, however they also increase levels of intracellular reactive oxygen species (ROS). We hypothesized that agents that cause oxidative stress might enhance the efficacy of HDACi. To test this hypothesis, we treated acute lymphocytic leukemia cells (ALL) with HDACi and adaphostin (ROS generating agent). The combination of two different HDACi (vorinostat or entinostat) with adaphostin synergistically induced apoptosis in ALL. This synergistic effect was blocked when cells were pre-treated with the caspase-9 inhibitor, LEHD. In addition, we showed that loss of the mitochondrial membrane potential is the …

Characterization Of Differentiation And Prognostic Biomarkers On Cd8+ Tumor-Infiltrating Lymphocytes In Metastatic Melanoma, Richard C. Wu

Dissertations and Theses (Open Access)

CD8⁺ cytotoxic T lymphocytes (CTL) frequently infiltrate tumors, yet most melanoma patients fail to undergo tumor regression. We studied the differentiation of the CD8⁺ tumor-infiltrating lymphocytes (TIL) from 44 metastatic melanoma patients using known T-cell differentiation markers. We also compared CD8⁺ TIL against the T cells from matched melanoma patients’ peripheral blood. We discovered a novel subset of CD8⁺ TIL co-expressing early-differentiation markers, CD27, CD28, and a late/senescent CTL differentiation marker, CD57. This CD8⁺CD57⁺ TIL expressed a cytolytic enzyme, granzyme B (GB), yet did not express another cytolytic pore-forming molecule, perforin (Perf). In …

A Home-Based Exercise Program For The Foot And Ankle To Improve Balance, Muscle Performance And Flexibility In Community Dwelling Older Adults: A Pilot Study, Laurel Long, Kurt Jackson, Lloyd L. Laubach

Background and purpose: Strength and range of motion of the foot and ankle have been shown to be related to measures of balance and fall risk in older adults. The primary purpose of this pilot investigation was to evaluate the feasibility of a 6-week home-based exercise program focusing on the foot and ankle and any associated changes in balance, muscle performance and range of motion in older adults. Methods: This single-group repeated measures study involved a convenience sample of 21 healthy communitydwelling older adults age 60-90. Nineteen participants completed all phases of the testing and training. The intervention was a …

A Comparison Of Upper Extremity Function Between Female Breast Cancer Survivors And Healthy Controls: Typical Self-Report Of Function, Motion, Strength, And Muscular Endurance, Mary Insana Fisher

Physical Therapy Faculty Publications

Many women who have experienced breast cancer (BC) report continued impairments in upper extremity (UE) function beyond the time required for normal healing after surgical treatment. Most research supporting this has not made comparisons between survivors of breast cancer (BCS) to a sample of healthy women. This lack of comparison to a healthy cohort prevents an understanding of whether continued deficits in UE function are due to normal aging or the BC treatment.

The purpose of this research was to compare quality of life (QOL) and UE function among long term breast cancer survivors and similar aged women without cancer. …
