The Acute Effects Of Different Foam Rolling Timing Durations On Hamstring Flexibility, Chloe Marie Kipnis

UNLV Theses, Dissertations, Professional Papers, and Capstones

The use of a foam roller is growing in popularity as a part of a warm-up in order to prepare for activity. The current research, however, lacks an accepted timing duration for how long an athlete should foam roll prior to activity in order to increase range of motion (ROM). In order to guide clinical practice, it is necessary to establish a standard for how long an athlete should foam roll a muscle group with the goal to increase ROM. Therefore, the purpose of this study was to compare hamstring flexibility changes following a single foam rolling bout, performed for …

The Role Of Mfd In Stationary-Phase Oxidative Damage Repair In Bacillus Subtilis, Katelyn E. Porter

UNLV Theses, Dissertations, Professional Papers, and Capstones

Since the 1950’s it has been shown that bacterial cells accumulate mutations even in non- dividing conditions, but how this type of mutation occurs is still highly debated. In Bacillus subtilis, Mfd, a precursor of the nucleotide excision repair (NER) system, mediates the formation of mutations in stationary-phase or non-replicating cells. In growing cells, Mfd recruits repair when RNA polymerase is stalled during transcription; it then recruits proteins from NER to repair damage. Here, we examine the hypothesis that Mfd mediates the formation of mutations by interacting with cellular components that repair reactive oxygen species (ROS), a natural byproduct of …

A Case Of Pituitary Abscess Presenting Without A Source Of Infection Or Prior Pituitary Pathology, Derick Adams, Philip A. Kern

Internal Medicine Faculty Publications

Pituitary abscess is a relatively uncommon cause of pituitary hormone deficiencies and/or a suprasellar mass. Risk factors for pituitary abscess include prior surgery, irradiation and/or pathology of the suprasellar region as well as underlying infections. We present the case of a 22-year-old female presenting with a spontaneous pituitary abscess in the absence of risk factors described previously. Her initial presentation included headache, bitemporal hemianopia, polyuria, polydipsia and amenorrhoea. Magnetic resonance imaging (MRI) of her pituitary showed a suprasellar mass. As the patient did not have any risk factors for pituitary abscess or symptoms of infection, the diagnosis was not suspected …

A Framework For Measurement Error In Self-Reported Health Conditions, Ling Li, Perry Singleton

Center for Policy Research

This study develops and estimates a model of measurement error in self-reported health conditions. The model allows self-reports of a health condition to differ from a contemporaneous medical examination, prior medical records, or both. The model is estimated using a two-sample strategy, which combines survey data linked medical examination results and survey data linked to prior medical records. The study finds substantial inconsistencies between self-reported health, the medical record, and prior medical records. The study proposes alternative estimators for the prevalence of diagnosed and undiagnosed conditions and estimates the bias that arises when using self-reported health conditions as explanatory variables.

3-Hydroxy Fatty Acid Induce Trophoblast And Hepatocyte Lipoapoptosis, Taylor Bruett, Taylor Heng, Sathish Kumar Natarajan

UCARE: Research Products

Acute Fatty Liver of Pregnancy (AFLP) is a very rare and fatal condition for both the mother and the unborn offspring accompanied by severe maternal liver dysfunction. AFLP usually develops during the third trimester of pregnancy with symptoms of liver disease. AFLP is associated with a mutation in the enzyme, long-chain 3-hydroxy acyl CoA dehydrogenase (LCHAD) which is involved in the mitochondrial beta-oxidation of fatty acids. Defective beta-oxidation of fatty acids results in the individual unable to metabolize fatty acids which then causes fatty infiltration in their organs, such as the liver. This interferes with normal function of the liver …

Elucidating The Genetic Cause To Ascites Syndrome In Broiler Chickens Utilizing Multi-Generational Genome Wide Association Studies, Katy Tarrant

Graduate Theses and Dissertations

Ascites syndrome in broiler chickens has developed into a source of economic loss in the last three decades. Intensive selective pressure, and implementation of flock management practices, has successfully reduced ascites frequency, but has not eliminated its occurrence. For this reason, it is imperative to better understand the genetic cause to ascites in broiler chickens. Previous studies of this magnitude have been attempted, but, thus far, a consensus of genomic associations have not been made. This collection of studies was aimed at identifying and interpreting genomic and genetic associations to ascites phenotype specific to a broiler line representative of a …

Effect Of Dung Beetles On Dung Decomposition And Nutrient Cycling In A Nebraska Rangeland, Kenneth Shay Evans

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Management practice can have impacts on the abundance and frequency of dung beetle populations and nutrient cycling in grazing systems. Also, agriculture and livestock production land use is a considerable source of anthropogenic greenhouse gas (GHG) emissions, which are known to be one of the causes of global climate change. In this study, we evaluated the effect of dung beetle presence on the fluxes of greenhouse gasses (GHG’s) from dung pats in the semi-arid Sandhills region of Nebraska, by using closed chambers to measure the fluxes of carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N …

Mediastinal Pancreatic Pseudocyst With Hemorrhage And Left Gastric Artery Pseudoaneurysm, Managed With Left Gastric Artery Embolization And Placement Of Percutaneous Trans-Hepatic Pseudocyst Drainage, Parag Brahmbhatt, Jason Mckinney, John Litchfield, Mehul Panchal, Thomas Borthwick, Mark Young, Lance Klosterman

ETSU Faculty Works

Mediastinal pancreatic pseudocyst (MPP) is a rare, but known, complication of both acute and chronic pancreatitis. Most pseudocysts are associated with alcoholic pancreatitis. Recent advances in endoscopic techniques have shown promising results, with reduced chances of infection and recurrence than with percutaneous drainage, but limited availability restricts widespread use. Left gastric artery pseudoaneurysm with mediastinal pseudocyst has not been described in the literature to date. We report a successful resolution of hemorrhagic MPP with embolization of pseudoaneurysm and percutaneous trans-hepatic pseudocyst drainage.

The Associations Among Expressed Emotion, Relationship Satisfaction, Ptsd Symptoms, Alcohol Use, And Depression: A Longitudinal Investigation With A Military Sample, Laci Lee Zawilinski

Dissertations

PTSD in military personnel is highly prevalent and accompanied by elevated rates of additional issues such as depression, problematic alcohol use, and interpersonal relationship problems. Family members and spouses of military personnel have also been shown to be negatively impacted by PTSD symptoms. Previous research has indicated that family members and spouses’ expressed emotion regarding the PTSD patients’ symptoms negatively impacts treatment outcome in civilian populations. However, studies have yet to investigate the effect of expressed emotion on the course of PTSD symptoms and associated problems in military personnel. Therefore, the purpose of the present investigation was to examine the …

Switchgrass Cultivar And Intraspecific Diversity Impacts On Nitrogen Use Efficiency, Aislinn Johns

Boise State University Theses and Dissertations

Bioenergy feedstock production is an important component of the national renewable energy strategy, which is based on biomass supply. Biofuels for ethanol production may be produced in high-input crop production systems, but the efficacy of these systems for increasing net energy yields over its full life-cycle compared to traditional fuels is under debate, because it is now evident that the benefits of feedstock production are maximized only when biofuels are derived from feedstocks produced with much lower life-cycle greenhouse-gas emissions than traditional fossil fuels. To this end, the reduction of agricultural inputs is key to developing an effective biofuel feedstock …
