A Temperature-Sensitive Mutant Of Escherichia Coli Affected In The Alpha Subunit Of Rna Polymerase, Majid Mehrpouyan

Electronic Theses and Dissertations

A temperature-sensitive mutant of Escherichia coli affected in the alpha subunit of RNA polymerase has been investigated. Gene mapping and complementation experiments placed the mutation to temperature-sensitivity within the alpha operon at 72 min on the bacterial chromosome. The rate of RNA synthesis in vivo and the accumulation of ribosomal RNA were significantly reduced in the mutant at 44$\sp\circ$C. The thermostability at 44$\sp\circ$C of the purified holoenzyme from mutant cells was about 20% of that of the normal enzyme. Assays with T7 DNA as a template showed that the fraction of active enzyme competent for transcription was reduced as a …

The Differences Between Industrial And Municipal Executives' Practices And Perceptions Of An Npdes Water Pollution Control System In Tennessee, Anthony L. Fulkerson

Electronic Theses and Dissertations

The purpose of this study was to determine the differences between industrial and municipal executives' practices and perceptions toward the administrative requirements of a water pollution control system as set forth in a National Pollutant Discharge Elimination System permit. This was a descriptive study that utilized a two-part attitudinal survey designed to obtain the perceptions of the executives (N = 171) of all major industries and all major municipalities in the State of Tennessee who had direct responsibility for the administrative requirements of an NPDES permitted water pollution control system. Descriptive statistics were used for the analysis of data with …

Electrophysiology, Cell Calcium, And Mechanisms Of Hepatocyte Volume Regulation, Walid E. Khalbuss

Electronic Theses and Dissertations

The electrophysiologic technique (Reuss, L., Proc. Natl. Acad. Sci. USA 82:6014, 1985) was modified to measure changes in steady-state hepatocyte volume during osmotic stress. Hepatocytes in mouse liver slices were loaded with tetramethylammonium ion (TMA$\sp{+}$) during transient exposure of cells to nystatin. Intracellular TMA$\sp{+}$ activity (a$\sp{\rm i}\sb{\rm TMA}$) was measured with TMA$\sp{+}$-sensitive, double-barreled microelectrodes. Loading hepatocytes with TMA$\sp{+}$ did not change their membrane potential (V$\sb{\rm m}$), and under steady-state conditions a$\sp{\rm i}\sb{\rm TMA}$ remained constant over 4 min in single impalements. Hyperosmotic solutions (50, 100, & 150 mM sucrose added to media) and hyposmotic solutions (sucrose in media reduced by …

The Effect Of Repetitive Midazolam Treatment On Acoustical Startle In Rats, Robert Francis Mirabella

Electronic Theses and Dissertations

Benzodiazepines are a class of drugs that have several actions including hypnotic features, anti-convulsant features, and anxiolytic features. Midazolam (MZ), a short acting benzodiazepine, is of special interest because of its probable high abuse potential and its efficacy as a preanesthetic.

Tolerance to drug effect has been found for both the hypnotic and anti-convulsant activity of benzodiazepines. Tolerance to the anxiolytic activity of benzodiazepines, however, is less clear. Evidence suggests that the time course for the development of tolerance associated with the anxiolytic action of MZ is slower than the time course associated with tolerance to the sedative and anticonvulsant …

Purification And Characterization Of Enoyl-Acp Reductase From Euglena Gracilis, Margie M. Tucker

Electronic Theses and Dissertations

Enoyl-(acyl-carrier-protein) reductase was purified from the phytoflagellate Euglena gracilis. Its purification employed DEAE-Sephacel chromatography, Matrex Orange chromatography, and affinity chromatography using acyl carrier protein (ACP) covalently bound to Sepharose as the affinity ligand. Matrex Orange chromatography resolved two different enoyl-ACP reductases having different characteristics. Euglena gracilis appears to resemble higher plants in the possession of two isoforms of this enzyme. Antibodies specific for the cofactor binding site of NADP (H)-requiring dehydrogenases were obtained. They were isolated from a polyclonal population of antibodies directed against yeast glucose-6-phosphate dehydrogenase by affinity chromatography using chicken liver malic enzyme as the affinity ligand. The …

Dopamine Agonists Modify The Development Of Brain D1 And D2 Receptor Responsiveness, Anwar A. Hamdi

Electronic Theses and Dissertations

Dopamine (DA) agonist-induced behavioral supersensitivity in the adult rat has served as the standard model for certain of the motor and behavioral side effects associated with long-term exposure to DA agonists in humans. The mechanisms relating receptor events with behavior mediation, however, remain unclear. The striatum of rats progresses through a prolonged and varied postnatal developmental period. In order to examine the relative contribution of D1 and D2 receptor-mediated mechanisms to behavioral changes which follow chronic dopamine agonist exposure, developing rats were treated daily from birth with a D1 agonist, SKF 38393 hydrochloride (3.0 mg/kg $\times$ 32d, i.p.), or a …

The Relationship Of Personality Type To Leader Style And Perceived Effectiveness Among Dental Hygiene School Administrators, Susan J. Willette

Electronic Theses and Dissertations

The purpose of this study was to identify personality types among dental hygiene school administrators and faculty and to determine if correlations existed between leader style, ideologies of leader style, perceived effectiveness, and personality type. Selected demographic variables were also examined. The dimensions of personality investigated were derived from the Myers-Briggs Type Indicator: extroversion, introversion, sensing, intuition, thinking, feeling, judging, and perceiving. The leadership behavior dimensions were the two dimensions of the real and ideal Leadership Behavior Description Questionnaires: consideration and initiating structure. Effectiveness was measured by a 39 item Likert-type instrument based on Tucker's (1981) categorical listing of chairperson …
