The Role Of Human Endogenous Retroviruses In Renal Cell Carcinoma, Michele D. Tisdale
The Role Of Human Endogenous Retroviruses In Renal Cell Carcinoma, Michele D. Tisdale
Biological Sciences Theses & Dissertations
Human endogenous retroviruses make up approximately 8-9% of the human genome. A number of expressed HERVs, those that are actively transcribing, have been associated with various cancers. Suppression mechanisms that control HERV expression often fail or become more permissive in tissues where expression should be restricted. Previous studies have identified HERV expression in breast cancer tissues, whereas normal tissue HERV expression remained suppressed. In addition, studies of DNA hypermethylation have correlated with the ability to contribute to cancer development. Hypermethylation of several tumor suppressor genes occurs frequently in cancers and alterations in promoter regions could contribute to the development of …
Inhibition Of Yeast Hexokinase By The Antimalarial Drug Artemisinin: Probing Mechanism Of Action With A Model Enzyme, Jennifer S. Spence
Inhibition Of Yeast Hexokinase By The Antimalarial Drug Artemisinin: Probing Mechanism Of Action With A Model Enzyme, Jennifer S. Spence
Biological Sciences Theses & Dissertations
A leading infectious cause of death, malaria threatens approximately half of the world's population, and drug-resistant strains of Plasmodium falciparum have created immense difficulty in chemotherapy of the disease. The artemisinin (ART) class of antimalarials may represent a powerful solution. In addition to their safety, effectiveness, and moderate cost, they are the only drugs in use for which there has been no widespread evidence of clinical resistance. The exact parasiticidal mechanism of ART is highly contested, but evidence suggests that protein alkylation may play a role in cytotoxicity. in vitro essays were performed using yeast hexokinase (HK) to demonstrate a …
Mechanisms Of Regulation Of Proximal Tubule Sodium Transporters In Obesity-Induced Hypertension, Marta A. Ambrozewicz
Mechanisms Of Regulation Of Proximal Tubule Sodium Transporters In Obesity-Induced Hypertension, Marta A. Ambrozewicz
Theses and Dissertations in Biomedical Sciences
Hypertension is one of the common complications of obesity. Using a rat model of diet induced obesity and hypertension we investigated some of the mechanisms that are involved in regulation of blood pressure in obesity. The first aim of this study was to determine the role of proximal tubule transporters on the renal sodium handling in obese hypertensive (OP) and lean normotensive (OR) rats. An acute increase in renal perfusion pressure resulted in a blunted natriuretic response in OP vs. OR rats and indicated that increased sodium reabsorption in the proximal tubule is casual, at least in part, for hypertension …
Immediate Effect Of Heel-Pain Orthosis And An Augmented Low-Dye Taping On Plantar Pressures And Pain In Subjects With Plantar Fasciitis, Tracy Andus
Human Movement Sciences & Special Education Theses & Dissertations
Research has been done investigating plantar pressures and pain in subjects with pathologies after the application of orthoses and arch taping. To date, however, no study has been conducted investigating plantar pressures and pain in subjects with plantar fasciitis after the application of the augmented low-dye taping (ALD) in comparison to a heel-pain orthosis (HPO). Therefore, the purpose of this study was to determine the effects of the ALD in comparison to a HPO on pain, peak plantar pressure (PPP), and mean plantar pressure (MPP) under multiple areas of the foot in subjects with plantar fasciitis while walking and jogging. …
The Effects Of Isolated Hamstring Fatigue On Jump Landing In Healthy Recreational Athletes, Kristen Anne Phillips
The Effects Of Isolated Hamstring Fatigue On Jump Landing In Healthy Recreational Athletes, Kristen Anne Phillips
Human Movement Sciences & Special Education Theses & Dissertations
The musculature of the lower extremity provides dynamic stability during daily and athletic tasks. In landing tasks, the lower extremity absorbs forces and reduces excessive stresses and motions that are placed upon the body. Neuromuscular fatigue has been linked to an increase in injury and altered kinematics during jump landing tasks. The purpose of this study was to analyze the effects of hamstring fatigue on knee and hip kinematics pre and post hamstrings fatigue while landing from a box drop of 30cm height, during the stop-jump phase. The study aimed to quantify the kinematic data of the hip and knee …

Aim: Reports on resting brain activity in healthy controls have described a default-mode network (DMN) and important differences in DMN connectivity have emerged for several psychiatric conditions. No study to date, however, has investigated resting-state DMN in relatively early depression before years of medication treatment. The objective of the present study was, therefore, to investigate the DMN in patients seeking help from specialized mental health services for the first time for symptoms of depression.
Methods: Fourteen depressed subjects and 15 matched controls were scanned using 4-T functional magnetic resonance imaging while resting with eyes closed. All but one subject was …

We have discovered a new, ultrafast therapy for treating skin cancer that is extremely effective with a total electric field exposure time of only 180 mu sec. The application of 300 high-voltage (40 kV/cm), ultrashort (300 nsec) electrical pulses to murine melanomas in vivo triggers both necrosis and apoptosis, resulting in complete tumor remission within an average of 47 days in the 17 animals treated. None of these melanomas recurred during a 4-month period after the initial melanoma had disappeared. These pulses generate small, long-lasting, rectifying nanopores in the plasma membrane of exposed cells, resulting in increased membrane permeability to …

Background: Menopause is associated with both a loss of muscle mass and a worsening of insulin sensitivity (IS). Although eccentric resistance exercise (ECC) can effectively improve muscle mass over time, a single bout of ECC can worsen IS. This study assessed the effect of repeated ECC on IS, muscle mass, and function in postmenopausal women with impaired glucose tolerance (IGT).
Methods: Sixteen PM women (aged 56 years +/- 6.4) with IGT were randomly assigned to a 12-week, knee extensor ECC program (n = 10) or a nonexercise control group (CON) (n = 6). Participants underwent hyperinsulinemic-euglycemic clamps, dual-energy …

Human monocytic ehrlichiosis (Ehrlichia chaffeensis), HME, is a tick-transmitted, rickettsial disease that has recently increased substantially in the USA from 142 reported cases in 2001 to 506 reported cases in 2005 [1,2]. There have been increasing surveys of tick populations over the past 10 years that have in turn supported the development of models for tick-borne disease transmission. Resulting HME models [3] suggest the importance of metapopulation structures, landscape environment parameters and periodic climatic effects in predicting the dynamics of HME transmission and the efficacy of control efforts, such as the reduction of the tick population through acaricide …
