Quantification of Poly(ADP-ribose) in Normal and in DNA-Damaged Cells

Description: This work presents the development of a new highly sensitive and selective chemical assay for poly(ADP-ribose) which is routinely useful for the determination of polymer levels in vivo. This method was used to carefully measure poly(ADP-ribose) levels in normal and in DNA-damaged cells. The results of these studies strongly suggest that synthesis of poly(ADP-ribose) is involved in some aspect of DNA repair. A review of the literature is presented in the introduction of this work. Poly(ADP-ribose) synthesis has been implicated in aspects of transcription, in DNA syn thesis, and in DNA repair largely based on evidence from in vitro studies. It is apparent that current methodology has not allowed the routine quantification of poly(ADP-ribose) in vivo, hence the lack of i^n vivo data concerning the function(s) of the polymer. The body of this work presents the development of two chemical methods for the quantification of poly(ADP-ribose) and the application of one of these methods to the measurement of polymer levels in normal and DNA-damaged cells. Preliminary studies are presented on the utilization of combined gas chromatography/mass spectroscopy for the selective quantification of nucleoside derivatives. A second method makes use of the unique chemistry of the polymer for quantification. The polymer was selectively adsorbed to dihydroxyboryl-sepharose which allowed the removal of most RNA, DNA, and protein from the samples. The polymer was hydrolyzed to the unique nucleoside 2'—^-l*'-ribosyladenosine by digestion with venom phosphodiesterase and bacterial alkaline phosphatase. The 1-N^-etheno derivative of ribosyladenosine was formed by reaction with chloroacetaldehyde and this derivative was seperated from other fluorescent species by reversed phase high pressure liquid chromatography.

A Collisional Mechanism in the Ion-Solid Interaction Which Enhances Scattering Yields Near 180⁰

Description: In the course of experiments using uniaxial double alignment channeling to investigate radiation damage in single crystals, an anomalously large ion-scattering yield from the near surface of disordered or simulated disordered solid targets was observed. The chronology of the discovery of this new ion-solid effect and its explanation are presented along with experiments detailing the dependence of the new effect upon ion type and energy, as well as target atomic number and density. Targets included a spectrum of polycrystalline elemental targets in a range Z = 29 to Z = 82. Also, the influence of the effect upon scattering yields from an aligned Au(110) single crystal is demonstrated.

Management Stress: A Correlational Study of Pragmatic Factors Relating to Educational Administrators

Description: This study provided administrators in a large southern metropolitan public school district an opportunity to participate in a stress-related research study. The questionnaire contained such stress-related probe areas as spiritual beliefs, preferred and imposed (perceived) orders of major-life emphasis areas, professional environment, personal-social environment, and probes into the ethical positions held by the administrators. The professional environment section contained subsets of internal (on-the-job) probes, external (political) probes, as well as personal (incentive) probes.The personal-social environment section was sub-divided into five Maslow hierarchy-of-need related probes such as physiological needs, safety-security needs, social needs, esteem needs, and self-fulfillment needs. The final section of the instrument sampled the administrators' responses to probes concerning their concepts of God, their concepts of the Bible arid their positions on eight ethical statements.

Mass/360

Description: Mass/360 is computer music in the sense that the audio tape was realized with a computer language for digital synthesis. This tape is combined with traditional choral and instrumental forces, and demonstrates only one technique available for the use of computers in composition. The work displays a number of elements which afford both unity and contrast. The arch span of the whole is supported by timbral, melodic, rhythmic, and textural parameters. Recurring events include tone clusters, chant-like melodies, angular melodies, and counterpoint. Special vocal effects are found in all movements, and the large scale tonicizing effect of the movement from f to b-flat gives the composition a sense of direction over a long temporal span. The single pitch (doubled unison/octave) arises as the major event in the work, and other events are generated from this element. The use of different formal designs within each movement corresponds to the natural textual divisions found in the liturgy, and affords a contrast from one movement to the next. The relationship of the Gloria/Qui Tollis to the Sanctus/Benedictus, which is not a mirror relation, contrasts with the chiastic design of the whole. Traditional contrapuntal devices juxtaposed against contemporary vocal techniques and the use of diversified timbres from movement to movement add variety to the composition. Controlling parameters in the Mass are timbral, harmonic, textural, and formal. Rhythmic and melodic parameters are of surface importance, and not considered in the higher structural levels of the composition. This particular handling of musical parameters as elements of unification and diversification is the foremost structural force at work in Mass/360.

An Application of Ridge Regression to Educational Research

Description: Behavioral data are frequently plagued with highly intercorrelated variables. Collinearity is an indication of insufficient information in the model or in the data. It, therefore, contributes to the unreliability of the estimated coefficients. One result of collinearity is that regression weights derived in one sample may lead to poor prediction in another model. One technique which was developed to deal with highly intercorrelated independent variables is ridge regression. It was first proposed by Hoerl and Kennard in 1970 as a method which would allow the data analyst to both stabilize his estimates and improve upon his squared error loss. The problem of this study was the application of ridge regression in the analysis of data resulting from educational research.

A Study to Assess Relationships Between Reading Achievement and Retention Of Prose

Description: This investigation was concerned with whether linguistic competence with printed material is related to the retention of information contained in prose passages of high readability. The specific purpose of the study was to investigate relationships between linguistic competence and free recall, immediate, delayed, and practiced, after the reading of a passage of high readability. In a review of related literature, indications were found that linguistic competence could be expressed by test scores of reading achievement. Therefore, in this study linguistic competence was operationally defined by scores of literal and inferential reading comprehension.

A Multi-Element Psychological Management Program for Chronic Low Back Pain

Description: This investigation utilized a novel, self-help, multi-element psychological program to manage chronic low back pain. A literature review indicated that this disorder was costly and prevalent, yet a large percentage of chronic low back pain patients did not respond to traditional treatment. Recent research has demonstrated that numerous psychological difficulties have been associated with this disorder, including depression and anxiety. It was hypothesized that these psychological concomitants of chronic low back pain maintain and promote further pain, as part of a vicious cycle. Self-help treatment attempted to break this tension-pain-anxiety cycle using various stress reduction, and cognitive and behavioral management strategies.

Regulation of Lactobacillic Acid Formation in Lactobacillus Plantarum

Description: Cyclopropanation of the unsaturated fatty acid moieties of membrane phospholipids is a commonly observed phenomenon in a number of bacterial systems. The cyclopropane fatty acids are usually synthesized during and after the transition from exponential growth to stationary phase, or under such environmental conditions as acidic culture pH, low oxygen tension or high salt concentrations. S-Adenosylmethionine, the ubiquitous methyl group donor, provides the methylene bridge carbon in the reaction catalyzed by cyclopropane fatty acid synthase. Also formed in the reaction is S-adenosylhomocysteine, a potent inhibitor of cyclopropane fatty acid synthase, which is degraded by S-adenosylhomocysteine nucleosidase. This work provides evidence for at least two modes of regulation of lactobacillic acid synthesis, the cyclopropane fatty acid formed from cis-vaccenic acid (cis-11,12-octadecenoic acid), in Lactobacillus piantarum.

An Empirical Investigation of the Potential Use of Data Required by FASB Statement No. 33 by Financial Analysts in the Dallas/Fort Worth and Houston Regions

Description: In September, 1979, the Financial Accounting Standards Board issued FASB Statement No. 33, which required certain corporations to issue specified supplementary information based on constant dollars and current costs. This information is intended to show the impact of inflation on the reported earnings and capital of business enterprises. Opponents of Statement No. 33 claim that the required supplementary information is difficult to interpret and, therefore, will not be used. Proponents contend that the information is self-explanatory and would highlight the impact of inflation on the performance of business enterprises. Thus, they conclude the supplementary data will be useful to various user groups and will be used. This dissertation's primary objective was to determine whether the supplementary data will be used by financial analysts in the Dallas/Fort Worth and Houston regions in evaluating an enterprise's operating performance and its ability to maintain physical operating capability and the general purchasing power of financial capital.
