Memory Consolidation in Avoidance-Conditioned Goldfish: Changes in Brain Protein-Synthetic Patterns
Three groups of goldfish were prepared; naive, avoidance-conditioned and pseudo-conditioned animals. Five pseudo-conditioned fish were avoidance trained later and found to have no measurable acquisition of the avoidance conditioning paradigm. Several protein fractions were found to have significantly different rates of synthesis when compared across groups. The possible involvement of these proteins in the memory storage process was discussed. digital.library.unt.edu/ark:/67531/metadc131377/
Memory Functions among Children Irradiated for Brain Tumor
Children who have received radiation therapy for the treatment of brain tumors have been shown to experience neurocognitive deficits which appear to increase over time. The purpose of this study was to examine the memory functioning of 22 children irradiated for brain tumor and 22 healthy children of the same age who had not received irradiation. Subjects were administered a brief form of the WISC-III, to obtain an IQ, and the Wide Range Assessment of Memory and Learning (WRAML), to evaluate visual and verbal memory. Results indicated that, although there were no significant differences between the IQ scores of healthy children and children who had been irradiated, children who have received radiation therapy for brain tumor evidence memory deficits which effect visual and verbal memory abilities. Among the children who had been irradiated, as time since treatment increased, visual memory and overall memory functioning appeared to decline. Findings also suggested that children who received total tumor resection may evidence greater memory deficits than those who received only a partial resection. Visual memory was more closely related to IQ in the children irradiated for brain tumor than in the healthy children. The overall importance of research with this population lies in refining the understanding of memory deficits and strengths in order to formulate more effective remediation compensation, strategies. digital.library.unt.edu/ark:/67531/metadc278041/
Memory Management and Garbage Collection Algorithms for Java-Based Prolog
Access: Use of this item is restricted to the UNT Community.
Implementing a Prolog Runtime System in a language like Java which provides its own automatic memory management and safety features such as built--in index checking and array initialization requires a consistent approach to memory management based on a simple ultimate goal: minimizing total memory management time and extra space involved. The total memory management time for Jinni is made up of garbage collection time both for Java and Jinni itself. Extra space is usually requested at Jinni's garbage collection. This goal motivates us to find a simple and practical garbage collection algorithm and implementation for our Prolog engine. In this thesis we survey various algorithms already proposed and offer our own contribution to the study of garbage collection by improvements and optimizations for some classic algorithms. We implemented these algorithms based on the dynamic array algorithm for an all--dynamic Prolog engine (JINNI 2000). The comparisons of our implementations versus the originally proposed algorithm allow us to draw informative conclusions on their theoretical complexity model and their empirical effectiveness. digital.library.unt.edu/ark:/67531/metadc2825/
Memory Patterns: Differentiated between Environmental Sensitive Patients and Psychiatric Patients
The purpose of the present study was to ascertain if environmentally sensitive patients would demonstrate different memory deficit patterns than psychiatric patients on objectively measurable memory tasks. One-hundred sixteen patients were surveyed; 56 environmentally sensitive patients were compared to 60 psychiatric patients. All subjects were administered a Wechsler Adult Intelligence Scale-Revised screen, the Wechsler Memory Scale-Revised and the Harrell-Butler Comprehensive Neurocognitive Screen after history of head injury was ruled out. Results indicate a significantly different pattern of memory dysfunction between the environmental patients and the psychiatric patients, indicating two different etiologies. A screening device derived from the coefficients from a Canonical Analysis is proposed to distinguish between the two populations in the absence of blood serum levels of environmental toxins or poisons. The detrimental effects of misdiagnosis and the beneficial effects of accurate diagnosis of environmental illness are discussed. digital.library.unt.edu/ark:/67531/metadc278534/

The Mental Health of Prospective Elementary Teachers
The purpose of this study was to determine the mental health assets and liabilities of prospective elementary teachers as compared with undergraduates outside the field of education. This investigation sought to determine differences in mental health adjustment between the prospective elementary teachers and undergraduates enrolled in selected divisions of a college other than the Department of Education. Additional attention was given to possible differences in mental health adjustment among the prospective elementary teachers when scholastic attainment, age, marital status, the urban-rural factor, and socio-economic status were considered. digital.library.unt.edu/ark:/67531/metadc164219/
Mental Health Professionals' Comparative Evaluations of the Integral Intake, The Life-Style Introductory Interview, and the Multimodal Life History Inventory
This research study was performed in an attempt to fill an apparent void regarding the relative utility and comprehensiveness of three published, theoretically-based, idiographic, initial assessment inventories: Integral Intake (II), Life-Style Introductory Interview (LI), and Multimodal Life History Inventory (MI). “Experts” -- defined as professors of counseling or psychology and licensed practitioners who have been practicing as counselors or psychologists for at least five years - read through the inventories and then evaluated them by responding to both (qualitative) open-ended questions as well (quantitative) rankings and ratings. The researcher posed three primary research questions: 1) how do participants' evaluations differ regarding the overall helpfulness of the three inventories; 2) how do participants' evaluations differ regarding the comprehensiveness -- both relative to each of the eight dimensions of the client (thoughts, emotions, behaviors, physical aspects of the client, physical aspects of the client's environment, culture, spirituality, and what is most meaningful to the client) and overall -- of the three inventories; and 3) how do participants' evaluations differ regarding the efficiency with which the three inventories assessed the eight dimensions. Results indicated that participants consistently evaluated the II and MI as more helpful, comprehensive, and efficient than the LI - both overall and relative to the eight specific dimensions. The LI was consistently evaluated as the worst of the three inventories -- on all dimensions. The MI was evaluated as the best inventory on four dimensions: the client's thoughts, emotions, behaviors, and physical aspects. The II was evaluated as the best inventory on seven dimensions: physical aspects of the client's environment, client's culture, client's spirituality, what is most meaningful to the client, and, notably, on overall comprehensiveness, overall efficiency, and overall helpfulness. Another goal of this research was to obtain feedback from the participants relative to how to improve the II. This goal was also accomplished and the researcher will implement this feedback into subsequent versions of the Integral Intake. digital.library.unt.edu/ark:/67531/metadc3231/

Mental Toughness: An Analysis of Sex, Race, and Mood
Mental toughness has become a focus for researchers as coaches, athletes, and others extol its influence in performance success. In this study I examined mental toughness among collegiate athletes, focusing on its potential relationship to different demographic variables and to the athletes’ mood. Two hundred seventy-two student-athletes representing 12 different sports from a southwestern NCAA Division I university, participated by completing the Sports Mental Toughness Questionnaire (SMTQ), the Brief Assessment of Mood (BAM), and providing demographic information. Analyses of variance (ANOVA) assessed differences in mental toughness scores by sex, race, scholarship status, and starting status. Significant differences in mental toughness emerged between Black – White, male – female, and full – partial – zero scholarship athletes. Pearson correlations showed mental toughness was significantly related to lower levels of anxiety, sadness, anger, confusion, fatigue, and total mood disturbance, and higher levels of vigor. digital.library.unt.edu/ark:/67531/metadc115045/
Mental Toughness Training for Police Officers: the Impact of a Stress Inoculation Program on Police Stress
This study examined the impact that a stress inoculation training (SIT) program had on a small-sized city police department in the southwestern U.S. Specifically, the aim of this study was to investigate how a SIT program impacted police officer self-reported levels of organizational stress, operational stress, perceived life stress, and mood states. All 24 participants were recruited from a population of 132 sworn, active duty police officers and were pre-tested through administration of a questionnaire packet containing a host of measures related to demographics, organizational stressors, operational stressors, general life stressors, and mood states. Participants were then randomly assigned to one of the following treatment conditions: (1) delayed training; (2) SIT program; and (3) SIT plus booster program. On completion of the SIT program, members of each of the treatment conditions were re-assessed through the administration of the aforementioned questionnaire packet. Subsequent to conducting the booster sessions, participants from each treatment condition took part in a second, and final, follow-up assessment. Results suggested that organizational stress was decreased for participants in the SIT program, particularly at follow-up. Results also suggested that energy (i.e., vigor) was increased for participants in the SIT plus booster program at both post-test and follow-up. Furthermore, results suggested that there was a statistically significant decrease in perceived life stress at both post-test and follow-up, yet statistically analysis was unable to tease out which group contributed to this significance. These findings support the efficacy of an SIT program in assisting police officers combat organizational stressors. digital.library.unt.edu/ark:/67531/metadc500044/

Mentoring in Family Firms : A Reflective Analysis of Senior Executives' Perceptions
This study is a reflective analysis of the perceptions of senior executives in family businesses that relate to their personal experiences of having been mentored. The study presents an overview of the topic of mentoring, defines key terms, and identifies questions addressed in the research. The rationale for this study rested on two facts. First, mentoring in non-family businesses constitutes the majority of the literature. That literature supports the importance of mentoring. Secondly, mentoring in family businesses has not been researched. digital.library.unt.edu/ark:/67531/metadc278701/
Mentoring in Higher Education Music Study: Are Good Teachers Mentors?
This quantitative study examined the correlation between how college level music students rated their teachers on the Fowler/O'Gorman Mentor Functions Questionnaire and how they perceived two aspects of their private music lessons: 1) to what extent they perceived their relationship with their teachers as positive, and 2) to what extent they perceived their teachers as good. The respondents for this study were 295 undergraduate and graduate music majors studying at 5 private universities or music schools. Positive correlations were found between the scores on the Mentor Functions Questionnaire (MFQ) and good teachers and positive lesson experiences. No correlation was found between the existence of gender congruity or the lack of gender congruity and the mean score on the MFQ. Respondents reported differences among their teachers' behaviors (p < .05): Role Modeling and Coaching behavior were perceived at significantly higher levels than the other six mentoring behaviors, whereas Friendship and Advocacy behavior was found at significantly lower levels. The behaviors of Personal and Emotional Guidance, Career Development Facilitation, Strategies and Systems Advice, and Learning Facilitation were found at levels closer to the mean. When role modeling and coaching behavior are present, students perceive teachers as good and lessons as positive. It is not necessary to be friends with a student in order to provide a positive lesson experience. Fowler and O'Gorman's mentoring behaviors have implications for improving the mentoring of collegiate music students. digital.library.unt.edu/ark:/67531/metadc30491/
Mentoring in Nursing Doctoral Education: Processes, Perceptions, Problems and Prospects
This study described the mentoring relationship between doctoral nursing students and their committee chairs. Twenty-two public university doctoral programs responded to a request for names and addresses of their doctoral candidates. The Major Professor Mentoring Scale was used to measure the mentoring relationship. The survey also included demographic and open-ended questions regarding the student-committee chair relationship. Surveys were mailed to 269 doctoral students with an 86% return rate. A principal components analysis was performed to identify the structure underpinning the relationship. The typical doctoral student in this sample was found to be a 44 year old Caucasian female, married with children, working full or part time while pursuing a PhD degree. Students traveled an average of 85 miles each way to campus and nearly half had selected their program based on its location. The typical committee chair was a Caucasian, tenured, associate or full professor between 46 and 69 years of age. The majority of chairs were married and had funded research projects. The students in the study reported knowing their chairs for an average of five years. The study revealed that mentoring is occurring in the majority of relationships between doctoral nursing students and their committee chairs. Students identified many strengths and weaknesses in their relationships with their chairs although the relationship appears to be largely positive. The mentoring relationship is composed of four principal components, the largest of which is psychosocial support. Dissertation support, role modeling and scholarly collaboration comprise the other three components. The factor receiving the most positive rating was role modeling, suggesting that students see their chairs as intelligent and hard-working. Students also report positive feelings about both the psychosocial and dissertation support they have received from their chairs. Students reported more neutral feelings about scholarly collaboration suggesting that this is not a frequent occurrence in the relationship. Demographic variables including age, sex, race, geographic distance and family status were not predictors for mentoring scores. digital.library.unt.edu/ark:/67531/metadc2190/
Mentoring the first-year superintendent in Texas public schools.
This study determined what mentoring experiences first-year superintendents have had and what they need from a mentoring relationship. Structured interviews and field notes were used in this qualitative study focused on Texas first-year superintendents' perceived needs from mentors. Three patterns of mentoring relationships were found: 1) no mentor in the first year, 2) mentor-protégé relationship - those who developed mentoring relationships early in a career with a more senior person in the same school system, and 3) mentoring relationships of convenience - young relationships which developed outside the same system. Skills and knowledge areas novice superintendents identified as critical for mentor assistance were school finance, development of effective relationships with groups that have expectations of the superintendent while also improving student achievement, and working within the politics of the position. Mentor characteristics novice superintendents considered necessary for a positive effect on job success include: trustworthiness, confidentiality, empathy, encouraging, active listening, and integrity. An attitude in which the mentor problem solved with the protégé, and did not give an immediate solution was displayed. Mentors actively and frequently initiated contact. Ideas were freely exchanged, giving the protégé undivided attention while not making the protégé feel inferior. The effects that previous mentoring experiences had on novice superintendents influenced whether they chose to mentor another person. Most reported seeking or engaged in a new mentoring relationship. Differences in areas where help was needed among first-year superintendents associated with district size were reported. Assistance in finance was needed regardless of district size, gender, or ethnicity. Superintendents in small districts reported needing assistance in specific skill and knowledge areas. Those in larger districts reported mentor assistance in problem-solving processes to accomplish a task. Differences in needs of first-year superintendents based on gender or ethnicity were identified but generalizations could not be made due to small numbers. Recommendations for university administrative preparation programs and designing formal mentoring programs were made. digital.library.unt.edu/ark:/67531/metadc3127/

A Meta-analysis of Burnout and Occupational Stress
The relationship between occupational stress and burnout was investigated through a meta-analysis of 81 studies and 364 correlations. Occupational stress was measured by role conflict, role ambiguity, workload, cumulative role stress, job specific stress/stressors, and work setting characteristics. Burnout was measured by the Maslach Burnout Inventory, 1981 and 1986 versions, emotional exhaustion, depersonalization, and reduced personal accomplishment components of burnout, measures of tedium, and the Staff Burnout Scale for Health Professionals. Thirty occupations in human and non-human service organizations throughout four publication periods were examined. Results indicated occupational stress strongly predicts burnout in non-human service organizations like industry and manufacturing as well as the human services. Job specific stressors most strongly predict burnout across organization types and occupation. Occupational stress predicts emotional exhaustion and depersonalization more than perceptions of reduced personal accomplishment. The findings support the use of transactional models of stress which consider occupational context as a precipitator of burnout, especially emotional exhaustion. digital.library.unt.edu/ark:/67531/metadc278263/
Meta-Analysis of Meditation Outcomes in Counseling and Psychtherapy
Meditation includes a variety of techniques that share a common conscious effort to focus attention in a non-analytic way. In terms of its goals, meditation is a state of completely focused attention devoid of external thoughts--a state of heightened choice-less awareness. This study was designed to: (1) Identify and critically review professional literature on the effectiveness of meditation; (2) Provide an overall measure of effectiveness through the statistical meta-analysis technique; (3) Provide a classification of findings through the voting method; and (4) summarize and integrate highlights and major findings for the purpose of generating implications for future research and practice in counseling and psychotherapy. digital.library.unt.edu/ark:/67531/metadc278465/
Meta-Analysis of Reading Interventions for Students with Learning and Emotional Disabilities
Developing effective literacy skill has become an increasingly critical skill in today's information age. Students with emotional/behavioral disorders (E/BD) routinely lack these skills and are not being taught how to read effectively. The field of special education needs more comprehensive and specific information about how to most effectively teach reading skills to students with E/BD. When reading interventions are conducted using student with E/BD, the interventions are generally drawn from the LD field. The assumption is that the reading interventions that have worked with students with LD will work equally well with the E/BD population. This study performed a meta-analysis to examine whether reading interventions are equally effective on the E/BD and LD populations. In addition, it will examine whether the instruction mode (e. g., peer, self, or teacher directed), gender, or grade group affects the success of the intervention. The meta-analysis found that the reading interventions for both disability groups had high effect sizes. In addition, neither disability group, teaching method, gender, nor grades were predictive of the variance in the effect size. These results indicate that reading programs that have been designed for students with LD are also effective for students with E/BD and furthermore, reading programs can improve the academic achievement of students with behavioral disorders. Recommendations for teacher training and future research are given based on these results. digital.library.unt.edu/ark:/67531/metadc4866/

Meta-Analysis of the Impact of After-School Programs on Students Reading and Mathematics Performance
The purpose of this study employing meta-analysis was to assess the impact that after-school programs have on reading and mathematics outcomes. The participants in the primary studies were students in Grades K through 8; years 200 through 2009. The study utilized the theory of change as its theoretical basis. This meta-analysis used the effect size as the standard measure. It began with an overall Cohen's d of .40 for the impact that after-school programs have on reading and mathematics outcomes, and then proceeded to analyze three moderator variables: subject, time periods, and grade level.The findings of the meta-analysis, both overall and sub analyses, show that the independent variable, after-school programs, has an impact on the dependent variable, reading and mathematics. The overall results indicated that after-school programs are educationally significant in the areas of reading and mathematics combined. As for the moderator variable, the results for the areas of (a) subject (reading and mathematics), (b) time period (2000-2002, 2003-2005 and 2006-2009), and (c) grade (middle, and middle plus elementary combined), all indicated educationally significant results. The notable exception was the grade moderator, elementary.This study provides more information for researchers, practitioners and policy makers upon which to make practical research based decisions about after-school programs for the purpose of determining the applicability of such in their educational setting. digital.library.unt.edu/ark:/67531/metadc67972/
Meta-Parenting in Parents of Infants and Toddlers
Access: Use of this item is restricted to the UNT Community.
Meta-parenting, defined as parents thinking about their parenting, has been identified and is a new field of research. The purposes of this study were to add to the existing knowledge of meta-parenting and to compare the influences of gender, work status, and parenting experience on meta-parenting occurring in parents of infants and toddlers. Sixty parents participated either electronically or by completing a written survey and reported engaging from "sometimes" to "usually" in four domains of meta-parenting: anticipating, assessing, reflecting, and problem-solving. Gender, work status, and parenting experience did not significantly influence participants' meta-parenting scores. Parents were found to have a higher sense of satisfaction and overall sense of competence when they engaged in higher levels of meta-parenting. digital.library.unt.edu/ark:/67531/metadc5566/

Metabolic, cardiac and ventilatory regulation in early larvae of the South African clawed frog, Xenopus laevis.
Early development of O2 chemoreception and hypoxic responses under normoxic (150 mmHg) and chronically hypoxic (110 mmHg) conditions were investigated in Xenopus laevis from hatching to 3 weeks post fertilization. Development, growth, O2 consumption, ventilatory and cardiac performance, and branchial neuroepithelial cells (NEC) density and size were determined. At 3 days post fertilization (dpf), larvae started gill ventilation at a rate of 28 ± 4 beats/min and showed increased frequency to 60 ± 2 beats/min at a PO2 of 30 mmHg. Also at 3 dpf, NECs were identified in the gill filament buds using immunohistochemical methods. Lung ventilation began at 5 dpf and exhibited a 3-fold increase in frequency from normoxia to a PO2 of 30 mmHg. Hypoxic tachycardia developed at 5 dpf, causing an increase of 20 beats/min in heart rate, which led to a 2-fold increase in mass-specific cardiac output at a PO2 of 70 mmHg. At 10 dpf, gill ventilatory sensitivity to hypoxia increased, which was associated with the increase in NEC density, from 15 ± 1 to 29 ± 2 cells/mm of filament at 5 and 10 dpf, respectively. Unlike the elevated rate, cardiac and ventilatory volumes were independent of acute hypoxia. Despite increased cardioventilatory frequency, larvae experienced an average of 80% depression in during acute hypoxia. Chronic hypoxia (PO2 of 110 mmHg) decreased mass-specific cardiac performance before 10 dpf. In older larvae (10 to 21 dpf), chronic hypoxia decreased acute branchial and pulmonary hypoxic hyperventilation and increased NEC size. Collectively, these data suggest that larvae exhibit strong O2-driven acute hypoxic responses post-hatching, yet are still O2 conformers. All acute hypoxic responses developed before 5 dpf, and then the effects of chronic hypoxia started to show between 7 and 21 dpf. Thus, the early formation of acute hypoxic responses is susceptible to the environment and can be shaped by the ambient PO2. digital.library.unt.edu/ark:/67531/metadc12175/
Metabolic Engineering in Plants to Control Source/sink Relationship and Biomass Distribution
Traditional methods like pruning and breeding have historically been used in crop production to divert photoassimilates to harvested organs, but molecular biotechnology is now poised to significantly increase yield by manipulating resource partitioning. It was hypothesized that metabolic engineering in targeted sink tissues can favor resource partitioning to increase harvest. Raffinose Family Oligosaccharides (RFOs) are naturally occurring oligosaccharides that are widespread in plants and are responsible for carbon transport, storage and protection against cold and drought stress. Transgenic plants (GRS47, GRS63) were engineered to generate and transport more RFOs through the phloem than the wild type plants. The transgenic lines produced more RFOs and the RFOs were also detected in their phloem exudates. But the 14CO2 labeling and subsequent thin layer chromatography analysis showed that the RFOs were most likely sequestered in an inactive pool and accumulate over time. Crossing GRS47 and GRS63 lines with MIPS1 plants (that produces more myo-inositol, a substrate in the RFO biosynthetic pathway) did not significantly increase the RFOs in the crossed lines. For future manipulation of RFO degradation in sink organs, the roles of the endogenous α-galactosidases were analyzed. The alkaline α-galactosidases (AtSIP1 and AtSIP2 in Arabidopsis) are most likely responsible for digesting RFOs in the cytoplasm and may influence the ability to manipulate RFO levels in engineered plants. Atsip1/2 (AtSIP1/AtSIP2 double-knockout plants) were generated and phenotypically characterized based on seed germination patterns, flowering time, and sugar content to observe the impact on RFO sugar levels. The observations and analysis from these lines provide a basis for further insight in the manipulation of resource allocation between source and sink tissues in plants for future research. digital.library.unt.edu/ark:/67531/metadc283836/
Metabolic Engineering of Raffinose-Family Oligosaccharides in the Phloem Reveals Alterations in Patterns of Carbon Partitioning and Enhances Resistance to Green Peach Aphid
Phloem transport is along hydrostatic pressure gradients generated by differences in solute concentration between source and sink tissues. Numerous species accumulate raffinose-family oligosaccharides (RFOs) in the phloem of mature leaves to accentuate the pressure gradient between source and sinks. In this study, metabolic engineering was used to generate RFOs at the inception of the translocation stream of Arabidopsis thaliana, which transports predominantly sucrose. To do this, three genes, GALACTINOL SYNTHASE, RAFFINOSE SYNTHASE and STACHYOSE SYNTHASE, were expressed from promoters specific to the companion cells of minor veins. Two transgenic lines homozygous for all three genes (GRS63 and GRS47) were selected for further analysis. Sugars were extracted and quantified by high performance anion exchange chromatography with pulsed amperometric detection (HPAEC-PAD), and 21-day old plants of both lines had levels of galactinol, raffinose, and stachyose approaching 50% of total soluble sugar. All three exotic sugars were also identified in phloem exudates from excised leaves of transgenic plants whereas levels were negligible in exudates from wild type leaves. Differences in starch accumulation or degradation between wild type and GRS63 and GRS47 lines were not observed. Similarly, there were no differences in vegetative growth between wild type and engineered plants, but engineered plants flowered earlier. Finally, since the sugar composition of the phloem translocation stream is altered in these plants, we tested for aphid feeding. When green peach aphids were given a choice between WT and transgenic plants, WT plants were preferred. When aphids were reared on only WT or only transgenic plants, aphid fecundity was reduced on the transgenic plants. When aphids were fed on artificial media with and without RFOs, aphid reproduction did not show differences, suggesting the aphid resistance is not a direct effect of the exotic sugars. digital.library.unt.edu/ark:/67531/metadc30441/
Metabolic Syndrome and Psychosocial Factors
Metabolic syndrome is a constellation of risk factors, including abdominal obesity, hypertriglyceridemia, low HDL cholesterol, high blood pressure, and high fasting glucose, that commonly cluster together and can result in cardiovascular disease. The prevalence of metabolic syndrome and the components that comprise the syndrome vary by age and by racial/ethnic group. In addition, previous research has indicated that the risk factors contributing to metabolic syndrome may be exacerbated by exposure to perceived stress. This study utilized data from the 2002, 2004, and 2006 Health and Retirement Study (HRS) and National Health and Nutrition Examination Survey (NHANES) data sets. It was hypothesized that depression and anxiety (conceptualized as stress in this study) increase the risk of presenting with metabolic syndrome while social support decreases the risk of metabolic syndrome. While results of cross-sectional analysis do not indicate a significant relationship between depression and metabolic syndrome (t = -.84, ns), longitudinal analysis does indicate a significant relationship between depression and metabolic syndrome over time (t = -5.20, p <.001). However, anxiety is not significantly related to metabolic syndrome when the relationship is examined through cross-sectional analysis (t = -1.51, ns) and longitudinal analysis (&#967;² = 13.83, ns). Similarly, social support is not significantly related to metabolic syndrome when examined in cross-sectional (&#967;² = .63, ns) and longitudinal (t = 1.53, ns) analysis. Although level of stress is not significantly related to metabolic syndrome as a whole, there is a significant relationship between stress and both triglyceride level (t = -2.94, p = .003) and blood glucose level (t = -3.26, p = .001). digital.library.unt.edu/ark:/67531/metadc11005/
Metabolism of Hydrocortisone by X-Irradiated Rat Liver Tissue as Determined by the Porter-Silber Chromagen Method
The present study may be considered endocrinological and radiobiological in nature. The endocrinology phase was concerned with studying the changes in endocrine function following the application of a stress agent. X-irradiation was chosen as the stressor in order to determine any difference in effect of this stressor from others which have been studied, e. g. heat, cold, metabolic poisons. Liver slices taken from rats at various time intervals following whole body X-irradiation were tested for their ability to metabolize hydrocortisone from a Krebs-Ringer solution. digital.library.unt.edu/ark:/67531/metadc108062/
