F Response Frequency For The Median And Ulnar Nerves In A Normal Population, Patricia J. Killea

Rehabilitation Sciences Theses & Dissertations

The F wave or F response results form the recurrent discharge of antidromically activated anterior horn cells. F response latency represents an impulse which travels to and from the spinal cord through the central segment of a nerve. Study of the F wave is commonly done to assess proximal conduction in motor nerves, to measure motor nerve conduction velocity over a longer pathway than in orthodromic motor studies, and to assess motor neuron excitability. F response characteristics less commonly studied include duration, chronodispersion, shape, amplitude, and frequency. The primary purpose of this study was to determine F response frequencies of …

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

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 …

Characterization Of A Novel Prostate Tumor-Associated Antigen, Grayson B. Lipford

Theses and Dissertations in Biomedical Sciences

The murine monoclonal antibodies (MAb) TURP-27 and HNK-1 have been shown to detect antigens that are heavily expressed by benign prostatic hyperplasia (BPH) and carcinoma of the prostate (CaP). Western blot analysis of prostate extracts, showed that MAb TURP-27 and MAb HNK-1 bound glycoproteins of 180, 140, 120, 100, 90 and 69 kDa. Studies have shown that the HNK-1 carbohydrate epitope may be involved in cell adhesion and that it is a component of several characterized adhesion proteins. TURP-27 was found to bind at least three of these adhesion proteins: neural cell adhesion molecules (N-CAM), myelin-associated glycoprotein (MAG) and a …

The Relationship Of Educational Attainment And Socioeconomic Factors In The Health Behaviors Of An Urban Population, George C. Maihafer

Theses and Dissertations in Urban Services - Urban Education

The purpose of this study was two fold: 1) to investigate the effects that level of educational attainment and income have on the health behaviors of an urban population, and 2) to examine the effects the level of motivation and selected demographic characteristics (e.g., age, race, gender) have on the study sample's perceived satisfaction with the medical encounter. Based on the findings of the study, a model community health education program was proposed. The study sample was comprised of 150 volunteers seeking health care for chronic conditions at a family practice clinic. The Krantz Health Opinion Survey (HOS) measured the …

The Effects Of Orthopaedic Surgery And Dorsal Rhizotomy On Selected Gait Characteristics Of Cerebral Palsy Children, Danielle M. Lanoue

Rehabilitation Sciences Theses & Dissertations

Surgical management of cerebral palsy children typically involves multiple orthopaedic surgeries in order to achieve and maintain the maximum functional level of ambulation. Orthopaedic intervention to address lower extremity spasticity often includes: muscle lengthenings, muscle releases and tendon transfers. The most recent advance in management of lower extremity spasticity has been through a neurosurgical approach; selective dorsal rhizotomy. The long term effects of dorsal rhizotomy are still being investigated. Through the use of instrumented gait analysis, the specific objective results of both of these types of surgeries can be investigated. The purpose of this retrospective study was to examine the …

Optimization Of Cryopreservation Protocols For Cardiovascular Tissue, Jianfei Hu

Theses and Dissertations in Biomedical Sciences

Radiolabeled inulin was demonstrated to be a useful marker for extracellular tissue space. Assessment of metabolic viability of the cellular population of leaflet tissue as a function of procurement and processing revealed that proline accumulation declined with increasing warm and cold ischemic times. Amphotericin B and streptomycin were toxic to the cells. Cefoxitin, lincomycin, polymyxin B, vancomycin and penicillin had …

Biodegradation Of Crude Oil By Marine Higher Fungi, Brian J. Dyer

Biological Sciences Theses & Dissertations

Four experiments were performed to determine the ability of marine higher fungi to grow in and degrade crude oil. Eight species, previously determined to be hydrocarbonoclastic, were grown in artificial sea water medium (ASM) and southern Louisiana crude oil. The dry mycelial weights were measured and consumption of crude oil was measured gravimetrically. The two species with the best growth, Corollospora maritima and Zalerion maritimum, were grown in ASM containing crude oil spiked with three known hydrocarbons. To this was added glucose (0.15%) and incubated 49 days to test for possible cometabolism of hydrocarbons. Hydrocarbons remaining in the growth …

A Comparison Of Two Theories Of Resistance To Innovation In Medical Record Administration Baccalaureate Degree Programs, Joyce Brown-Harvey

Health Services Research Dissertations

Resistance to innovation is a major obstacle to the successful implementation of planned change in colleges and universities. The purpose of this study was to compare two explanations of resistance to innovation to determine which one best explains the variance in receptivity and proposed innovations among faculty members in medical record administration programs. One explanation holds that organizational members' receptivity to change is a function of their personalities. The second explanation holds that members respond to specific innovations and that they do so in terms of whether the innovation would increase or reduce their present status.

The faculty of baccalaureate …
