Characterization Of Metal-Regulated Genes In Pseudomonas Fluorescens, Melanie Pearson
Characterization Of Metal-Regulated Genes In Pseudomonas Fluorescens, Melanie Pearson
Honors Theses
One side effect of today's industrialized world is increased levels of heavy metals in the environment. Many of these metals are necessary for biological function as trace elements, but at higher concentrations are toxic. Other metals, such as cadmium, are not beneficial at any level, and have only deleterious effects on living organisms. Cadmium is primarily thought to interfere with normal biological function of proteins. Human exposure to cadmium appears to primarily damage the kidneys, but may also affect the liver, lungs, immune system, and central nervous system. Bacteria, however, have developed several methods for handling toxic heavy metals: cation …
A Model Using Radiation And Pws4-Htnf-Α Gene Therapy For Treatment Of Glioblastomas, Angelo G. Baher
A Model Using Radiation And Pws4-Htnf-Α Gene Therapy For Treatment Of Glioblastomas, Angelo G. Baher
Loma Linda University Electronic Theses, Dissertations & Projects
The efficacy of radiotherapy for cancer is limited by the dose that can be safely delivered to the tumor without causing debilitating side effects. In addition, successful treatment of highly malignant tumors such as glioblastomas is likely to require adjunctive therapies to enhance tumor response to radiation. Previous studies have shown immunomodulation and a synergestic reduction in tumor volume of malignant tumors when tumor necrosis factor-α (TNF-α) protein is administered prior to radiation. The major goal of the present investigation was to evaluate the efficacy of pWS4-human TNF-α (pWS4-hTNF-α), a new plasmid construct that expresses human TNF-α protein, together with …
Methicillin Resistant Staphylococcus Aureus (Mrsa): Molecular Detection And Dna Fingerprinting, Leslie Cotter
Methicillin Resistant Staphylococcus Aureus (Mrsa): Molecular Detection And Dna Fingerprinting, Leslie Cotter
Theses
Throughout the 1990s, the incidence of methicillin-resistant Staphylococcus aureus has increased in many health care areas including acute and chronic care facilities, outpatient clinics and in the community. Once introduced into a health care environment, this nosocomial pathogen can spread rapidly and as MRSA are resistant to multiple antibiotics, treatment is often difficult. Therefore effective infection control measures are required to prevent cross-infection and further spread of endemic strains.
In this study, a sensitive and specific triplex-PCR assay was designed for MRSA detection, wherein three genes, the methicillin resistance gene (mecA). femA and the extracellular thermonuclease gene (rmc) were simultaneously …
Molecular Analysis Of The Factor V-Leiden Mutation In A Cardiac Transplant Patient Population, Caroline Maher
Molecular Analysis Of The Factor V-Leiden Mutation In A Cardiac Transplant Patient Population, Caroline Maher

Venous thrombosis is a serious health problem affecting 1 in 1000 individuals annually. Until recently the pathogenic factors underlying thrombosis were associated with genetic defects in protein C, protein S and antithrombin III. However these were recognised in fewer than 5-10% of thrombotic patients. A breakthrough was made with the discovery of activated protein C resistance (APCr) which is associated in 90% of cases v/herein a G-->A transition in the factor V gene results in an abnormal molecule, Factor V Leiden. APCr is a major risk factor for thrombosis being present in 20-60% of thrombotic patients. Recently a G-^A …
