Lack Of Delayed-Type Hypersensitivity In Striped Bass (Morone Saxatilis), Jessica Shannon Miller
Biological Sciences Theses & Dissertations
Mycobacteriosis is a fatal disease in fishes caused by acid-fast bacteria in the genus Mycobacterium. This disease impacts aquaculture, aquariums, and wild fishes. Unfortunately, there are currently no non-lethal diagnostic tests for mycobacterial infection in fishes. Type IV delayed type hypersensitivity (DTH) responses in vivo and in vitro are currently used for the non-lethal detection of mycobacterial infections in humans and in animals; however, there is little information available on DTH responses in fishes. In this work, we examine in vivo DTH response in Striped Bass (Morone saxatilis), an important U.S. Eastern seaboard fish species, experimentally …

In Vitro Selection Of Chloroquine Tolerant Plasmodium Falciparum Parasites, Daniel A. Daley
In Vitro Selection Of Chloroquine Tolerant Plasmodium Falciparum Parasites, Daniel A. Daley
Biological Sciences Theses & Dissertations
Malaria is among the most devastating human diseases, and a majority of lethal cases are caused by the protozoan parasite, Plasmodiumfalciparum. The emergence of multi-drug resistant P.falciparum is a major obstacle to malaria control and is highlighted by the abandonment of chloroquine (CQ) as a first-line treatment of P.falciparum infections worldwide. Chloroquine resistance (CQR) is associated primarily with mutations in the transmembrane digestive vacuole protein, PfCRT. However, CQR P.falciparum parasites harboring the same mutant pfcrt allele vary in their CQ response, suggesting the CQ response is multigenic in nature. No gene outside of pfcrt is completely associated with CQR. Thus, …
Novel Architecture Of Costal Cartilage And Implications In Chest Wall Deformities, Anthony J. Asmar
Novel Architecture Of Costal Cartilage And Implications In Chest Wall Deformities, Anthony J. Asmar
Biological Sciences Theses & Dissertations
Costal cartilage is a type of hyaline cartilage that forms rod-like structures that connect the ribs to the sternum. Deformation of costal cartilage is observed in the chest wall deformities, pectus excavatum and pectus carinatum. Pectus excavatum involves a sternal displacement causing a depression of the chest while pectus carinatum causes a protrusion of the chest. As costal cartilage is not a widely studied tissue, this leaves little knowledge into possible factors involved in the pathogenesis of pectus deformities. Costal cartilage in these deformities has been described as being weakened and may implicate proteoglycans which play an important role in …
Patterns Of Gene Expression From Human Costal Cartilage In Relation To The Chest Wall Deformity Pectus Carinatum, Janna E. Grubbs
Patterns Of Gene Expression From Human Costal Cartilage In Relation To The Chest Wall Deformity Pectus Carinatum, Janna E. Grubbs
Biological Sciences Theses & Dissertations
Cartilage deformities within the human chest wall, specifically pectus excavatum (PE) and pectus carinatum (PC) are common (1/400-1/1000) and yet, despite their clinical significance, are some of the least studied disorders pertaining to cartilage [1]. The costal cartilage connecting "false ribs" 8-10 to the sternum is often abnormally grown and can lead to formation of a severely sunken "funnel" chest (PE) or push outwards to form a "pigeon" chest (PC). Both conditions can have impact on the diaphragm, heart, lungs, and psychological function. An established ratio of PE and PC in males to females is 4:1, indicating a sex-linked male …

These consequences include a toll of 83,000 deaths and an economic impact between 1,5 and 5 billion. Approaches to strategy selection by physicians and other health-care specialists are based mainly upon cost, technology availability, and cultural tolerance regarding radiation exposure. The purpose of this study was to determine the most cost-effective diagnostic strategy with patients suspected of PE among several strategies currently used by examining their detection failure rates. This objective was met by (a) assessing parameter …
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
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 …

OES Theses and Dissertations
Vibrio cholerae serotypes 01 and 0139 are responsible for world-wide epidemics of cholera. These pandemic causing strains must possess genes that encode for the cholera toxin (CTX) and toxin co-regulated pili (TCP) in order to infect their hosts. In this study, 284 isolates of Vibrio cholerae from ballast and coastal waters were serotyped, with 11 % testing positive for serotype 01 and 21 % testing positive for serotype 0139. PCR assays were used to detect the presence of ctxA and tcpA genes in all positive isolates, none of which contained ctxA while 2% of the isolates contained tcpA. The 01 …
Chromosomal Localization Of The Islet Neogenesis Associated Protein (Ingap) Gene In Syrian Hamster By Tyramide Signal Amplification-Fluorescence In Situ Hybridization (Tsa-Fish), Sallie A. Smith
Biological Sciences Theses & Dissertations
Diabetes mellitus is a group of conditions characterized by hyperglycemia due to an inability to produce or properly utilize insulin. The majority of cases fall into two categories, Type I and Type 2. Type I results from the autoimmune destruction of pancreatic β-cells of the islets. The beta cells are the exclusive source of insulin and the patient becomes entirely dependent on exogenous insulin to survive. Patients with Type 2 are distinguished by insulin resistance, a condition that develops due to the inability of the body to effectively use the insulin being produced. The β-cells gradually lose their ability to …

HIV/AIDS poses an enormous health threat to African Americans, specifically African American women. According to the Center for Disease Control "1 in 160 African American women are believed to be infected with HIV (Center for Disease Control 1999:1). In 2000, although African American women only represented 12% of the female population, they accounted for 64% of HIV cases reported among women (The White House 2000; National Institute of Allergy and Infectious Diseases 2004).
This study examined HIV/AIDS and African American women and attempted to answer the question: Why are African American women not consistently using condoms to protect themselves against …
The Ecological Ramifications Of Disease And Density In The Caribbean Spiny Lobster, Panulirus Argus, Donald C. Behringer Jr.
The Ecological Ramifications Of Disease And Density In The Caribbean Spiny Lobster, Panulirus Argus, Donald C. Behringer Jr.
Biological Sciences Theses & Dissertations
In 1999, I discovered the first virus known to be pathogenic to any species of lobster. HLV-PA is a pathogenic herpes-like virus that infects juvenile Caribbean spiny lobster, Panulirus argus, in the waters off south Florida (USA), and it alters the behavior and ecology of this species in fundamental ways. Gross signs of HLV-PA infection are lethargy, morbidity, cessation of molting, and discolored, “milky” hemolymph that does not clot. HLV-PA infects the hemocytes of host lobsters, specifically the hyalinocytes and semi-granulocytes, but not the granulocytes. When hemolymph from infected donors was injected into healthy juvenile lobsters, 90% of the …

A Study On The Effects Of The N-Terminal Amino Acid Sequence On The Activation Of Human T-Cell Leukemia Virus Type 1 Protease, Hidayah Muhammad Kendall
Chemistry & Biochemistry Theses & Dissertations
Human T-cell leukemia virus type 1 (HTL V-1) is dependent upon the enzymatic activity of its protease for maturation. Maturation of the protease is facilitated by cleavage of specific amino acid residues, followed by dimerization. The effects of the amino acid sequence located N-terminally to the cleavage site on the ability of the protease to become active were the focus of the current study. These amino acid sequences were contributed by the plasmid vector into which the protease gene was inserted.
Surface probability analyses (SPAs) of the vectors, as well as for native sequences which produce the mature protease and …
An Enzyme-Linked Immunosorbent Assay For The Detection Of Cardiac Myoglobin Using Monoclonal Antibodies, Deborah F. Kelly
An Enzyme-Linked Immunosorbent Assay For The Detection Of Cardiac Myoglobin Using Monoclonal Antibodies, Deborah F. Kelly
Chemistry & Biochemistry Theses & Dissertations
The most prevalent life-threatening disease worldwide, secondary to coronary artery thrombosis is Acute Myocardial Infarction (AMI). Increases in three clinical markers have been explored as an early means of AMI detection: Cardiac myoglobin, and the two specific cardiac isoforms of Creatine Kinase, CK-MM and CK-MB. However, myoglobin levels have shown to give a more accurate correlation (R = 0.89) than does Creatine Kinase evaluation. Therefore, we have developed a two-site Enzyme-Linked Immunosorbent Assay (ELISA) using monoclonal antibodies against myoglobin isolated from human heart tissue. This assay is based on specific anti-genantibody interactions and is sensitive at the nanogram level. We …

Recently, it has been reported that human type I iodothyronine deiodinase, an enzyme important in the conversion of T4 to T3 , is a selenoenzyme. Several studies have reported alterations in plasma selenium level in hypo- and hyperthyroid patients.
Using polarized Zeeman-effect atomic absorption spectroscopy, we measured selenium, zinc, copper and manganese concentrations in the plasma and/or red blood cells in children with or without thyroid disease being seen at the outpatient clinic at Children's Hospital of the King's Daughters. Children with thyroid disease were subdivided into untreated, treated and nonresponsive groups. Data were analyzed using Student's t-test …
Longitudinal Study Of Plasma And Erythrocyte Selenium Levels In Type I Diabetic Children During Development And Treatment Of Ketoacidosis, Pi-Hsia Fan
Chemistry & Biochemistry Theses & Dissertations
Most studies on the biological activity of selenium have focused on its role at the active site in the ubiquitous enzyme, glutathione peroxidase (GSH-Px) which catalyzes the removal of hydrogen peroxide and organic hydroperoxides (1). A connection between selenium deficiency and a wide range of diseases in animals and humans has been reviewed (2). Development of various forms of human cancer (3), failure of the immune system (4), as well as some cardiovascular diseases (5) have been reported or suspected to correlate with selenium deficiency. However, the physiological function of selenium in these different diseases is not fully understood, and …
Kinetic Characterization Of A Recombinant C-Terminal Mutant Of Reverse Transcriptase From The Human Immunodeficiency Virus, Thomas S. Heard
Kinetic Characterization Of A Recombinant C-Terminal Mutant Of Reverse Transcriptase From The Human Immunodeficiency Virus, Thomas S. Heard
Chemistry & Biochemistry Theses & Dissertations
The human immunodeficiency virus (HIV) reverse transcriptase (RT) (EC 2.7.7.49) is the central replication enzyme for HIV. In general, the kinetic mechanism for this and all other polymerases involves the ordered binding of two substrates: a primer-template (PT) followed by a deoxyribonucleoside triphosphate (dNTP). Previous investigations prompted this research when it was discovered that the substrate dNTP, in absence of PT, could protect a recombinant c-terminal mutant HIV-1 RT from inhibition by pyridoxal-5'-monophosphate (PLP), an active-site dNTP inhibitor. In contrast, the non-mutant recombinant HIV-1 RT required both substrates for protection from PLP inhibition. This investigation sought to determine if this …
Biochemical Investigation Of Gout And Its Familial Incidences, Chin-Ling Hsu
Biochemical Investigation Of Gout And Its Familial Incidences, Chin-Ling Hsu
Chemistry & Biochemistry Theses & Dissertations
Gout is a chronic metabolic disorder caused by deposition of uric acid on the joint. It is categorized into two types: primary and secondary. Primary gout is uric acid overproduction, caused by excessive synthesis of the purine precursors. Secondary gout occurs also as the result of overproduction or decreased renal excretion of uric acid resulting from other disease processes or medication.
The two purine bases, hypoxanthine and xanthine, liberated from ribosides by the action of nucleoside phosphorylase, are degraded to uric acid as the final excretory product in the purine degradation pathway. Hypoxanthine and xanthine are the physiological substrates of …
