Opiate Receptor Subtype Modulation Of Dopaminergic Activity The Effects Of Mu, Kappa And Sigma Opiates On The Development Of Dopaminergic Supersensitivity, Robert W. Dunn

Open Access Dissertations

The purpose of this research was to examine the effects of mu (μ), kappa (κ) and sigma (o) agents namely, morphine (μ), ethylketocyclazocine (κ), SKF 10,047 (σ), pentazocine (κ, o), cyclazocine (κ, σ) and the mu antagonists, naloxone and naltrexone on dopamine mediated behaviors and the development of haloperidol-induced dopaminergic supersensitivity (DA-SS) in the mouse. Three behavioral paradigms were utilized which are predictive of mesolimbic and/or striatal dopaminergic effects: locomotor activity (mesolimbic); apomorphine-induced stereotyped behavior (striatal) and apomorphineinduced climbing behavior (mesolimbic/striatal). Morphine, SKF 10,047, pentazocine and cyclazocine produced increases in locomotor activity suggesting increased dopaminergic activity, while naloxone and naltrexone …

Studies On The Metabolism Of Astaxanthin In The Rainbow Trout (Salmo Gairdneri), Abdulrhaman Salih Al-Khalifah

Open Access Dissertations

Racemic astaxanthin was fed to rainbow trout (Salmo gairdneri) for 2, 4, and 6 weeks. The fish showed a bright pink coloration of the skin and flesh; the highest amount of astaxanthin (162 ug/100g) was found in the skin of fish fed the test diet for six weeks. Lutein, 3-epilutein, and zeaxanthin were also detected in the flesh and skin; it was concluded that astaxanthin was converted to zeaxanthin in the skin. The mean vitamin A content of the liver was determined; the ratio of vitamin A₁: vitamin A₂ was approximately 1:3. There was no …

Creativity, Attention Deployment, And Equilibration, Joseph R. Mcallister Jr.

Open Access Dissertations

This investigation examines the relevance of Piagetian theory for understanding creativity. Selected studies of creativity using a variety of methodologies and deriving from diverse theoretical orientations are reviewed with the purpose of demonstrating a common link among seemingly unrelated investigations, namely, their congruence with a Piagetian theory of creativity.

Three subtopic areas are considered in more detail: attention deployment of creatives, similarities and differences between creatives and schizophrenics, and Kuhn's theory of scientific revolutions. An attempt is made to relate the findings from each of these areas to a Piagetian perspective on creativity.

Subjects were 104 undergraduate student. A tachistoscopic-type …

Causal Inferences Among Perceived Work And Nonwork Stress And Satisfaction, And Psychological Distress: Empirical Tests Of Path-Analytic Models, Jocelyn J. Johnson

Open Access Dissertations

The present investigation was designed to integrate work and nonwork domains in the study of perceived stress, satisfaction, and psychological distress. Causal inferences among perceived work and nonwork stress and satisfaction, and psychological distress were determined by empirically testing two basic path-analytic models depicting causal relationships among those variables.

Data were obtained from a sample of 105 female clerical workers on five variables (work stress, nonwork stress, work satisfaction, nonwork satisfaction, and psychological distress) and support for the contention that work and nonwork domains are interdependent was found. Nonwork variables contributed more to perceived psychological distress than work factors.

Short Stature In Caucasian Males: Personality Correlates And Social Attribution, Leslie F. Martel

Open Access Dissertations

Given the advent of genetically engineered human growth hormone, there is a pressing need to better understand the personality correlates and impact of short stature in males. One hundred-twenty college age Caucasian males of short, average and tall stature were administered measures of self-concept, body-cathexis, psychological security, and a semantic-differential measure. In addition, a questionnaire regarding the importance of height in daily life was also included.

The broadly-based literature review strongly suggests that short stature in males is a distinct developmental and social liability.

The results of the present study supported the first prediction that short subjects would feel significantly …

An Investigation Of The Effect Of Some Formulation And Manufacturing Variables On The Wet Granulation Process, Sambasiva Rao Ghanta

Open Access Dissertations

A Hobart mixer was instrumented with a slip ring torque sensor, signals were amplified and the output was recorded using a Bascom-Turner recorder. The relative dynamic torque on the paddle was measured in millivolts as a function of granulating fluid added and time. The data generated from a formulation containing lactose, corn starch and povidone were reproducible. The maximum relative standard deviation was less than two percent at any time point on the torque curve. Formulations containing lactose, dicalcium phosphate and mannitol matrices (with four different drugs) shoed five distinct phases in the torque profile. Phases I, II, and III …

An Investigation Of The Effect Of Holocaust Survivor Parents On Their Children, Cynthia Budick

Open Access Dissertations

Studies of the Holocaust have shown that the Concentration Camp victims were traumatized in so massive a fashion as to make a permanent and irreversible change in their character.

The purpose of the present research was to make a direct inquiry into whether the character traits and symptoms of the survivors had an effect on character structure and personality of their children. Further, it was an attempt to distinguish two groups of survivors' children: children of survivors who were adolescents in the Concentration Camps and children of survivors who were adults in the Concentration Camps.

Drug- Cyclodextrin Inclusion Compounds. Studies Of The Formulation Of Pharmaceutical Products Containing Cyclodextrins., Ramachandra P. Hegde

Open Access Dissertations

Interaction of beta-cyclodextrin with ampicillin, phenobarbitone, and phenytoin was studied and complexation was observed with all three drugs. Analytical methods for the quantification of these drugs were validated. In order to obtain an inclusion compound in the solid powdered form, a variety of methods (freeze drying, spray drying, kneading, and solvent evaporation) was evaluated. Among these methods freeze drying was the most feasible and reproducible method from a laboratory scale to a pilot scale and to the manufacturing level. Methods using an industrial model freeze drier were developed which resulted in an increase in yield from 53% to more than …

The Role Of The Orientation Response In The Cognitive Control Of Leveling And Sharpening, David J. Libon

Open Access Dissertations

Heart rate orientation responses were taken while subjects were administered two tests of leveling and sharpening. The first leveling and sharpening test was neutral in content while the second was designed to be affectively arousing. Subjects were also administered the aggression scale from the Edwards Personal Preference Scale (EPPS) and classified into low and high aggression groups. It was predicted that the use of attention is a major cognitive distinction between levelers and sharpeners. Heart rate orientation responses were used as a measure of attention. It was predicted that sharpeners would exhibit greater orienting behavior than levelers and these attentional …
