An Epidemiological Assessment Of Lung Function Decline As A Predictor Of Morbidity And Mortality, Penelope J. Baughman Jan 2011

An Epidemiological Assessment Of Lung Function Decline As A Predictor Of Morbidity And Mortality, Penelope J. Baughman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Excessive lung function decline is associated with increased risks of respiratory morbidity and mortality outcomes including chronic obstructive pulmonary disease (COPD). COPD is a disease afflicting approximately 80 million people worldwide and as of 2002, the fifth leading cause of death. COPD is an increasing problem, with substantial increases projected in COPD deaths if there is no reduction of the causal risk factors. By 2030, COPD is projected to be the third leading cause of death worldwide, an increase mainly due to extended life expectancies and that COPD deaths occur at older ages. COPD is also largely underdiagnosed, partially due …

Subcellular Distribution Of Apoptosis Associated Speck-Like Protein Mediates Inflammasome Assembly: A Novel Mechanism In The Regulation Of Interleukin-1beta Release, Nicole B. Bryan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Inflammation is an essential component of the innate immune defense against pathogens. The process of inflammation is mediated by the rapid release of intercellular mediators, which function in the activation and recruitment of cellular components of both the innate and adaptive immune system. However, dysregulation of this process, resulting in sustained inflammation is the underlying cause of a number of common pathological conditions. These include hereditary autoinflammatory disorders, gout, arthritis, asthma, and cancer. Furthermore, IL-1beta is a key component of the tumor microenvironment, which serves to recruit tumor-associated macrophages, promote angiogenesis, enhance NF-kB activation, and suppress anti-tumor immunity. The studies …

Breast cancer remains one of the leading causes of cancer related death among women worldwide. Numerous reports have provided evidence of a role of inflammation in the onset and progression of many cancers, including breast cancer. A mechanism that leads to inflammation involves the arachidonic acid (AA) pathway, which leads to the production of a group of pro-inflammatory bioactive lipids, collectively known as the eicosanoids. Despite evidence of AA and the eicosanoids in cancer, limited work has been done on the enzyme cytosolic phospholipase A2 (cPLA2) that provides the unesterified AA that can be used for eicosanoid generation.

Diet Induced Alterations And Distribution Of Indices Of Lysine Catabolism, Stephanie K. Gatrell Jan 2011

Diet Induced Alterations And Distribution Of Indices Of Lysine Catabolism, Stephanie K. Gatrell

Graduate Theses, Dissertations, and Problem Reports (ETD)

Lysine is thought to be oxidized primarily by lysine alpha-ketoglutarate reductase (LKR) and saccharopine dehydrogenase (SDH), which are restricted to the mitochondrial matrix. Lysine is presumably transported through the plasma membrane by isoforms(s) of a cationic amino acid transporter (CAT). Although the mechanism(s) of lysine transport through the inner mitochondrial membrane is not known, it is presumptively transported by one or both mitochondrial "ornithine transporters" (ORC-1/ORC-2). Tissue distribution of LKR and the mechanism(s) responsible for alterations in hepatic lysine catabolism in swine are unclear. Also, the roles of the alternative pathways of lysine degradation, the L-amino acid oxidase-dependent (LAAO), in …

Mechano-Enzymatic Pretreatment Of Lignocellulosic Biomass, Bibu Philip George Jan 2011

Mechano-Enzymatic Pretreatment Of Lignocellulosic Biomass, Bibu Philip George

Graduate Theses, Dissertations, and Problem Reports (ETD)

Recalcitrance of lignocellulosic cell wall is a major hurdle that needs to be disrupted for biochemical refinery to be successful. Pretreatment of lignocellulosic materials play a key role for the conversion of lignocellulosic feed stocks to fermentable sugars. At present, various pretreatment technologies mainly achieved by empirical methods are available for the production of sugars from lignocellulosic polysaccharides. These methods depend largely upon the "demolition" of the cell wall by strong chemicals or using high energy input. As a result, these processes release "smaller compounds" as by-products or end products which inhibits downstream fermentation of monomeric sugars.;This project is a …

Effects Of Acute And Repeated Administration Of Diazepam On Delay Discounting In Lewis And Fischer 344 Rats, Sally L. Huskinson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Impulsive choice is often examined using a delay-discounting procedure where choice is between two reinforcers of different magnitudes presented at varying delays. Individual discounting rates can be influenced by many factors including strain differences and drug effects. Lewis (LEW) and Fischer 344 (F344) rats have behavioral and neurochemical differences relevant to delay discounting and were used to examine effects of acute and repeated diazepam administration on impulsive choice. Consistent with previous literature, larger-reinforcer choice decreased as a function of increasing delays for all rats, and steeper discounting functions occurred for LEW relative to F344 rats. Acute and repeated diazepam administration …

Water Gas Shift Reaction Catalysis Promoted By Selective Sorption Of Carbon Dioxide: Microreactor Experiments, Ramanjaneyulu Katta Jan 2011

Water Gas Shift Reaction Catalysis Promoted By Selective Sorption Of Carbon Dioxide: Microreactor Experiments, Ramanjaneyulu Katta

Graduate Theses, Dissertations, and Problem Reports (ETD)

Production of hydrogen via the water-gas shift (WGS) reaction normally requires multiple reaction steps followed by CO2 separation. However, in-situ removal of CO2 via the carbonation reaction between CaO and CO2 provides the opportunity to combine WGS and separation reactions into a single unit. Consequently, the need for heat exchangers between catalyst beds as well as the absorption and stripping units for CO2 removal can be eliminated.;In this study, a commercial high-temperature-shift (HTS) catalyst, Fe 2O3/Cr2O3/CuO is used. Calcium oxide (CaO) and calcium oxide incorporated with calcium aluminate (Ca12Al 14O33) are used as sorbents for CO2 capture. The CaO/Ca12Al14O33 sorbent …

Vegetative Compatibility In Arbuscular Mycorrhizal Fungi, Sonia Purin Jan 2011

Vegetative Compatibility In Arbuscular Mycorrhizal Fungi, Sonia Purin

Graduate Theses, Dissertations, and Problem Reports (ETD)

The process of anastomosis promotes interconnectivity between hyphal branches during formation of a mycelial network and between fungal colonies. Self anastomosis involves fusion within a mycelium from a germinating spore, and this process is common in all species of fungi. Non-self anastomosis involves fusion between hyphae from different spores or colonies and allows lateral gene transfer, but this process is much rarer. Anastomosis in Ascomycota is well studied, but little is known for asexual arbuscular mycorrhizal fungi (AMF) in Glomeromycota. Because AMF are obligate symbionts in plant roots, studies have focused on anastomosis in asymbiotic hyphae of germinating spores. To …
