Spirituality In Late Adulthood, Lisa M. Heintz, Imants Barušs

Psychology

MacDonald's Expressions of Spirituality Inventory was used to examine spirituality in late adulthood using a sample of 30 people (22 women, 8 men) whose mean age was 72.6 yr. While average scores are higher on scales measuring spiritual and religious beliefs and practices for the sample than for a standardization group of undergraduate students with a mean age of 21.0 yr., means are lower on scales measuring paranormal beliefs. Low scores on death anxiety are correlated only with Existential Well-being and age. And, while some religious behaviors such as frequent religious practice, prayer, and church attendance are correlated with some …

Perceived Family Relationships Associated With Coming Out Of Mormon Male Homosexuals, Brad Benson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study is one of the first to include data from both male homosexuals and their family members to investigate disclosure of sexual orientation. Being homosexual in U.S. society can be particularly traumatic for males because strong pressures oppose the violation of masculine gender norms. Being homosexual and Mormon has unique complications. Reactions from the Mormon community toward individuals of homosexual orientation is defined by prevailing attitudes toward homosexuality, which are largely based on existing theories of etiology, attribution of etiology, and the religious and cultural beliefs extant in the community. The role of family relationships in the coming out …

Characterization Of The Cd154-Positive And Cd40-Positive Cellular Subsets Required For Pathogenesis In Retrovirus-Induced Murine Immunodeficiency, Kathy A. Green, Randolph J. Noelle, Brigit G. Durell, William R. Green

Dartmouth Scholarship

Genetically susceptible C57BL/6 (B6) mice that are infected with the LP-BM5 isolate of murine retroviruses develop profound splenomegaly, lymphadenopathy, hypergammaglobulinemia, terminal B-cell lymphomas, and an immunodeficiency state bearing many similarities to the pathologies seen in AIDS. Because of these similarities, this syndrome has been called murine AIDS (MAIDS). We have previously shown that CD154 (CD40 ligand)-CD40 molecular interactions are required both for the initiation and progression of MAIDS. Thus, in vivo anti-CD154 monoclonal antibody (MAb) treatment inhibited MAIDS symptoms in LP-BM5-infected wild-type mice when either a short course of anti-CD154 MAb treatment was started on the day of infection or …

Altered Operant Responding For Motor Reinforcement And The Determination Of Benchmark Doses Following Perinatal Exposure To Low-Level 2,3,7,8-Tetrachlorodibenzo-P-Dioxin, Vincent P. Markowski, Grazyna Zareba, Sander Stern, Christopher Cox, Bernard Weiss

Psychology

Pregnant Holtzman rats were exposed to a single oral dose of 0, 20, 60, or 180 ng/kg 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on the 18th day of gestation. Their adult female offspring were trained to respond on a lever for brief opportunities to run in specially designed running wheels. Once they had begun responding on a fixed-ratio 1 (FR1) schedule of reinforcement, the fixed-ratio requirement for lever pressing was increased at five-session intervals to values of FR2, FR5, FR10, FR20, and FR30. We examined vaginal cytology after each behavior session to track estrous cyclicity. Under each of the FR values, perinatal TCDD exposure …

Prolonged Cyclooxygenase-2 Induction In Neurons And Glia Following Traumatic Brain Injury In The Rat, Kenneth I. Strauss, Mary F. Barbe, Renee Marshall Demarest, Ramesh Raghupathi, Samir Mehta, Raj K. Narayan

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Cyclooxygenase-2 (COX2) is a primary inflammatory mediator that converts arachidonic acid into precursors of vasoactive prostaglandins, producing reactive oxygen species in the process. Under normal conditions COX2 is not detectable, except at low abundance in the brain. This study demonstrates a distinctive pattern of COX2 increases in the brain over time following traumatic brain injury (TBI). Quantitative lysate ribonuclease protection assays indicate acute and sustained increases in COX2 mRNA in two rat models of TBI. In the lateral fluid percussion model, COX2 mRNA is significantly elevated (>twofold, p < 0.05, Dunnett) at 1 day postinjury in the injured cortex and bilaterally in the hippocampus, compared to sham-injured controls. In the lateral cortical impact model (LCI), COX2 mRNA peaks around 6 h postinjury in the ipsilateral cerebral cortex (fivefold induction, p < 0.05, Dunnett) and in the ipsilateral and contralateral hippocampus (two- and six-fold induction, respectively, p < 0.05, Dunnett). Increases are sustained out to 3 days postinjury in the injured cortex in both models. Further analyses use the LCI model to evaluate COX2 induction. Immunoblot analyses confirm increased levels of COX2 protein in the cortex and hippocampus. Profound increases in COX2 protein are observed in the cortex at 1-3 days, that return to sham levels by 7 days postinjury (p < 0.05, Dunnett). The cellular pattern of COX2 induction following TBI has been characterized using immunohistochemistry. COX2-immunoreactivity (-ir) rises acutely (cell numbers and intensity) and remains elevated for several days following TBI. Increases in COX2-ir colocalize with neurons (MAP2-ir) and glia (GFAP-ir). Increases in COX2-ir are observed in cerebral cortex and hippocampus, ipsilateral and contralateral to injury as early as 2 h postinjury. Neurons in the ipsilateral parietal, perirhinal and piriform cortex become intensely COX2-ir from 2 h to at least 3 days postinjury. In agreement with the mRNA and immunoblot results, COX2-ir appears greatest in the contralateral hippocampus. Hippocampal COX2-ir progresses from the pyramidal cell layer of the CA1 and CA2 region at 2 h, to the CA3 pyramidal cells and dentate polymorphic and granule cell layers by 24 h postinjury. These increases are distinct from those observed following inflammatory challenge, and correspond to brain areas previously identified with the neurological and cognitive deficits associated with TBI. While COX2 induction following TBI may result in selective beneficial responses, chronic COX2 production may contribute to free radical mediated cellular damage, vascular dysfunction, and alterations in cellular metabolism. These may cause secondary injuries to the brain that promote neuropathology and worsen behavioral outcome.

Children Of Alcoholics: An Update., D Z Lieberman

Psychiatry and Behavioral Sciences Faculty Publications

One of four children in the United States lives in a family in which the child is exposed to alcoholism. Children of alcoholics (COAs) are two to ten times more likely to develop alcoholism than non-COAs. This paper reviews studies that have attempted to identify risk factors that mediate the increased vulnerability and the protective factors that moderate the risk. Factors discussed include parental antisocial personality disorder, externalizing behavior, internalizing symptoms, differential response to the effects of alcohol, and positive and negative alcohol-related expectancies. The heterogeneous nature of COAs is emphasized, and some of the challenges related to treatment and …

Ubinuclein, A Novel Nuclear Protein Interacting With Cellular And Viral Transcription Factors., S Aho, M Buisson, T Pajunen, Y W Ryoo, J F Giot, H Gruffat, A Sergeant, Jouni Uitto

Department of Dermatology and Cutaneous Biology Faculty Papers

The major target tissues for Epstein-Barr virus (EBV) infection are B lymphocytes and epithelial cells of the oropharyngeal zone. The product of the EBV BZLF1 early gene, EB1, a member of the basic leucine-zipper family of transcription factors, interacts with both viral and cellular promoters and transcription factors, modulating the reactivation of latent EBV infection. Here, we characterize a novel cellular protein interacting with the basic domains of EB1 and c-Jun, and competing of their binding to the AP1 consensus site. The transcript is present in a wide variety of human adult, fetal, and tumor tissues, and the protein is …

The Pl(A2) Polymorphism Of Integrin Beta(3) Enhances Outside-In Signaling And Adhesive Functions., K Vinod Vijayan, Pascal J. Goldschmidt-Clermont, Christine Roos, Paul F. Bray

Cardeza Foundation for Hematologic Research

Genetic factors are believed to influence the development of arterial thromboses. Because integrin alpha(IIb)beta(3) plays a crucial role in thrombus formation, we analyzed receptor adhesive properties using Chinese hamster ovary and human kidney embryonal 293 cells overexpressing the Pl(A1) or Pl(A2) polymorphic forms of alpha(IIb)beta(3). Soluble fibrinogen binding was no different between Pl(A1) and Pl(A2) cells, either in a resting state or when alpha(IIb)beta(3) was activated with anti-LIBS6. Pl(A1) and Pl(A2) cells bound equivalently to immobilized fibronectin. In contrast, significantly more Pl(A2) cells bound to immobilized fibrinogen in an alpha(IIb)beta(3)-dependent manner than did Pl(A1) cells. Disruption of the actin cytoskeleton …

Sulfa Or Sulfone Prophylaxis And Geographic Region Predict Mutations In The Pneumocystis Carinii Dihydropteroate Synthase Gene, Laurence Huang, Charles B. Beard, Jennifer Creasman, Deborah A. Levy, Jeffrey S. Duchin, Sherline Lee, Norman Pieniazek, Jane L. Carter, Carlos Del Rio, David Rimland, Thomas R. Navin

Journal Articles: Epidemiology

To determine factors associated with mutations in the Pneumocystis carinii dihydropteroate synthase (DHPS) gene, a prospective study of human immunodeficiency virus (HIV)-infected patients with confirmed P. carinii pneumonia was conducted in Atlanta, Seattle, and San Francisco. Clinical information was obtained from patient interview and chart abstraction. DHPS genotype was determined from DNA sequencing. Overall, 76 (68.5%) of 111 patients had a mutant DHPS genotype, including 22 (81.5%) of 27 patients from San Francisco. In multivariate analysis, sulfa or sulfone prophylaxis and study site were independent predictors of a mutant genotype. Fourteen (53.8%) of 26 patients who were newly diagnosed with …

The Emotional Modulation Of Cognitive Processing: An Fmri Study, Joseph Simpson, Dost Ongür, Erbil Akbudak, Thomas Conturo, John Ollinger, Abraham Snyder, Debra Gusnard, Marcus Raichle

Open Access Publications

The functional neuroanatomy of visual processing of surface features of emotionally valenced pictorial stimuli was examined in normal human subjects using functional magnetic resonance imaging (fMRI). Pictorial stimuli were of two types: emotionally negative and neutral pictures. Task performance was slower for the negatively valenced than for the neutral pictures. Significant blood oxygen level dependent (BOLD) increases occurred in the medial and dorsolateral prefrontal cortex, midbrain, substantia innominata, and/or amygdala, and in the posterior cortical visual areas for both stimulus types. Increases were greater for the negatively valenced stimuli. While there was a small but significant BOLD decrease in the …

Intimate Partner Violence Among Men And Women In South Carolina, 1998, Ann L. Coker, Christina Derrick, Julia L. Lumpkin, Robert Oldendick, R H. Potter

CRVAW Faculty Journal Articles

Few studies provide population-based estimates of intimate partner violence (IPV) for men and women, especially at the state level. IPV may result in adverse health effects for victims and perpetrators (1-3). To estimate the lifetime incidence of IPV by type of violence (e.g., physical, sexual, and perceived emotional abuse) and to explore demographic correlates of reporting IPV among men and women, the South Carolina Department of Health and Environmental Control and the University of South Carolina conducted a population-based random-digit-dialed telephone survey of adults in the state. This report summarizes the results of the survey, which indicated that approximately 25% …

Clients' Internal Representations Of Their Therapists, Sarah Knox, Julie L. Goldberg, Susan S. Woodhouse, Clara E. Hill

College of Education Faculty Research and Publications

Thirteen adults in long-term individual psychotherapy were interviewed regarding their internal representations (defined as bringing to awareness the internalized "image") of their therapists. Results indicated that in the context of a good therapeutic relationship, clients' internal representations combined auditory, visual, and kinesthetic (i.e., felt presence) modalities; were triggered when clients thought about past or future sessions, or when distressed; occurred in diverse locations; and varied in frequency, duration, and intensity. Clients felt positively about their representations and used them to introspect or influence therapy within sessions, beyond sessions, or both. The frequency of, comfort with, and use of clients' internal …

The Effects Of Free Fatty Acids On Gluconeogenesis And Glycogenolysis In Normal Subjects, X Chen, N Iqbal, G Boden

Rowan-Virtua School of Osteopathic Medicine Departmental Research

We have quantitatively determined gluconeogenesis (GNG) from all precursors, using a novel method employing 2H20 to address the question of whether changes in plasma free fatty acids (FFA) affect GNG in healthy, nonobese subjects. In the first study (n = 6), plasma FFA were lowered at 16 to 20 hours with nicotinic acid (NA) and were then allowed to rise at 20 to 24 hours (FFA rebound after administration of NA). FFA decreased from 387 microM at 16 hours to 43 microM at 20 hours, and then rebounded to 1,823 microM at 24 hours. GNG decreased from 58.1% at 16 …

Resurgence Of Sleeping Sickness In Tambura County, Sudan, Anne Moore, Michaleen Richer, Mario Enrile, Edward Losio, Jacquelin Roberts, Deborah A. Levy

Journal Articles: Epidemiology

Endemic foci of human African trypanosomiasis are present in southern Sudan. In 1996 and 1997, trypanosomiasis increased sharply in Tambura County. To define the magnitude and geographic distribution of the outbreak, we conducted a prevalence survey using population-based cluster sampling in 16 villages: 1,358 participants answered questions about routine activities and tsetse fly contact and received serologic testing. Seroprevalence in the surveyed area was 19.4% (95% confidence interval = 16.9%, 21.8%). We confirmed infection in 66% of seropositive persons who received one parasitologic examination and in 95% of those who had serial examinations of lymph node fluid and blood. Activities …

Written Retellings Of Narrative And Expository Texts: A Case Study Of Elementary Primary Grade Delayed Male Readers, Timothy Todd Houge

UNLV Retrospective Theses & Dissertations

This study examined how four second grade delayed readers, who were delayed in various stages of reading and writing, read and wrote about narrative and expository paired-topic texts. This study was based on the assumption that: (a) elementary primary grade children could read and write about narrative and expository texts; (b) delayed readers are children who can learn to read, even though they are below grade level, if they are given the opportunity; and, (c) written retellings could be used to assess students' understanding of texts and are one method of bringing the reading-writing relationship together; A case study research …

Using Porn: Discourse And Identity Construction In Male Consumers, Andrew Fletcher Harper

UNLV Retrospective Theses & Dissertations

A number of cultural perspectives address the question of male consumers of heterosexually oriented pornography. Porn and the consumer have been characterized from feminist, conservative, and scientific positions. Despite the presence of these perspectives, little work informed from the consumer perspective exists. This research allows consumers to speak about their own experience. This research analyzes the impact of framing discourses on the identity construction of consumers. Using concepts from Foucault and cultural studies, these questions are explored: How do discourses about consumers affect their identity construction? Which are important? How do men construct their consuming experiences? How does consumption context …

Isolation Of Lautropia Mirabilis From Oral Cavities Of Human Immunodeficiency Virus-Infected Children, S. N. Rossmann, P. H. Wilson, J. Hicks, B. Carter, S. G. Cron, C. Simon, C. M. Flaitz, G. J. Demmler, W. T. Shearer, M. W. Kline

Faculty, Staff and Student Publications

Lautropia mirabilis, a pleomorphic, motile, gram-negative coccus, has been isolated from the oral cavities of 32 of 60 (53.3%) children infected with human immunodeficiency virus (HIV) and 3 of 25 (12.0%) HIV-uninfected controls; the association of L. mirabilis isolation with HIV infection is significant (P < 0.001). All children in the study, both HIV-infected children and controls, were born to HIV-infected mothers. The presence of this bacterium was not associated with clinical disease in these children. The HIV-infected children with L. mirabilis did not differ from the HIV-infected children without L. mirabilis in immunological status, clinical status, or systemic medications. The role of HIV infection itself or concomitant factors in the establishment of L. mirabilis in the oral cavity remains to be elucidated.

How Do Hmos Achieve Savings? The Effectiveness Of One Organization's Strategies., Ann B. Flood, Allen M. Fremont, K Jin, David M. Bott

Dartmouth Scholarship

To examine how a group practice used organizational strategies rather than provider-level incentives to achieve savings for health maintenance organization (HMO) compared to fee-for-service (FFS) patients. A large group practice with a group model HMO also treating FFS patients. Data sources were all patient encounter records, demographic files, and clinic records covering 3.5 years (1986-1989). The clinic's procedures to record services and charges were identical for FFS and HMO patients. All FFS and HMO patients under age 65 who received any outpatient services during approximately 100,000 episodes of the seven study illnesses were eligible.

Clinician Perceptions Of Media Use By Male Sex-Offending, Conduct-Disordered, And Normal Youth, Melissa A. Vogel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sexual offenses by youth have been increasing. The literature recognizes media as a socializer, yet few studies examine nonpornographic media and youthful sex-offending. The purpose of this research was to survey the perceptions of clinicians as to the use of media type and content for male sex-offending, conduct-disordered, and normal youth. The questionnaire was completed by 78 American clinicians from 30 states specializing in the treatment of youthful sex offenders.

Means, standard deviations, and percentages were calculated, which provided descriptive data. Male sex-offending and conduct-disordered youth are believed by clinicians to be more frequent consumers of aggressive, explicit, and sexually …

Treatment Of Nocturnal Enuresis In Four Male Adolescent Sex Offenders, Deloy Herman Johnson

Undergraduate Honors Capstone Projects

Over the three months of this study, the subjects were detained 24 hours per day, every day at a residential center for sex offenders. Of the four subjects, three received medications for nocturnal enuresis while the other one received medication for hyperactive behavior. The time interval between nocturnal events increased for the recipients of sensitivity training. This study was a three-month study without follow up. The increased interval may be explained by two other confounds that were not measured: 1) the clients who had the longer intervals at the end of the study were also on medication, which possibly contributed …

The Baculovirus Anti-Apoptotic P35 Protein Promotes Transformation Of Mouse Embryo Fibroblasts., M Resnicoff, B. Valentinis, D. Herbert, D. Abraham, P D. Friesen, E. S. Alnemri, R Baserga

Department of Microbiology and Immunology Faculty Papers

The baculovirus p35 protein is a potent inhibitor of programmed cell death induced by a variety of stimuli in insects, nematodes, and mammalian cell lines. The broad ability of p35 in preventing apoptosis has led us to investigate its effect on mouse embryo fibroblasts in vitro and in vivo. For this purpose, we have used R- cells (3T3-like fibroblasts derived from mouse embryos with a targeted disruption of the insulin-like growth factor I receptor (IGF-IR) genes) and R508 cells (derived from R- and with 15 x 10(3) IGF-IRs per cell). Both cell lines grow normally in monolayer, but they do …
