Wild Primate Populations In Emerging Infectious Disease Research: The Missing Link?, Nathan D. Wolfe, Ananias A. Escalante, William B. Karesh, Annelisa Kilbourn, Andrew Spielman, Altaf A. Lal

Harold W. Manter Laboratory of Parasitology: Library Materials

Wild primate populations, an unexplored source of information regarding emerging infectious disease, may hold valuable clues to the origins and evolution of some important pathogens. Primates can act as reservoirs for human pathogens. As members of biologically diverse habitats, they serve as sentinels for surveillance of emerging pathogens and provide models for basic research on natural transmission dynamics. Since emerging infectious diseases also pose serious threats to endangered and threatened primate species, studies of these diseases in primate populations can benefit conservation efforts and may provide the missing link between laboratory studies and the well-recognized needs of early disease detection, …

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.

Regeneration In Periodontal Defects With Rhbmp-2 : A Dosage Study, Paola Guglielmoni

Loma Linda University Electronic Theses, Dissertations & Projects

Bone morphogenetic proteins (BMPs) have been shown to induce bone formation in ectopic and orthotopic sites. This inductive capability has led to their evaluation as possible adjuncts in periodontal reconstructive therapy. Indeed, studies have reported periodontal regeneration following surgical implantation of recombinant human BMP-2. This study evaluated regeneration of alveolar bone and cementum following periodontal reconstructive surgery including implantation of a construct consisting of sterile lyophilized rhBMP-2 in buffer adsorbed onto an absorbable collagen sponge. Critical size mandibular supra-alveolar periodontal defects were surgically created, and an incomplete block design was used to evaluate the regenerative potential of rhBMP-2 at 0.05, …

Parent-Teen Communication About Sexual Topics, Marcela Raffaelli, Karen Bogenschneider, Mary Fran Flood

Department of Psychology: Faculty Publications

Parent-teen communication about sexual topics was examined in 666 mother-teen and 510 father-teen pairs. Parents and their 8th- through 12th-grade children completed parallel surveys that assessed demographic, relationship, and attitudinal variables hypothesized to be linked to sexual communication. Logistic regression analyses were used to determine which variables were linked to teens’ reports of “one good talk” about each of three sexual topics (whether teen sex is okay, the dangers of AIDS and other sexually transmitted diseases, and birth control) in the past year. Aside from gender of parents and teens, demographic variables were largely nonsignificant in the final models. Instead, …

“Other Teens Drink, But Not My Kid”: Does Parental Awareness Of Adolescent Alcohol Use Protect Adolescents From Risky Consequences?, Karen Bogenschneider, Ming-Yeh Wu, Marcela Raffaelli, Jenner C. Tsay

Department of Psychology: Faculty Publications

This study included 199 White mother-adolescent dyads and 144 White father-adolescent dyads. All adolescents reported regular alcohol use, yet less than one third of parents were aware of their adolescents’ drinking. Parental awareness of adolescent alcohol use served to protect adolescents by moderating the relation of parents’ responsiveness to episodes of drinking and driving. Aware parents were more likely than unaware parents to believe their adolescents’ close friends drank alcohol. Aware mothers worried more about their adolescents’ risk behaviors and discussed them more frequently with their adolescents. Aware fathers held values less disapproving of adolescent alcohol use and were less …

Knowledge, Attitudes And Behavior Of African American Undergraduate College Students Concerning Primary Preventative Health, Lionas Mayes

McCabe Thesis Collection

African Americans' knowledge about primary preventive health and their attitudes toward primary preventive health influence their health behavior. Primary preventive health behavior is also affected by the individuals' definition of health and the significance they ascribe to their health status. Attitudes toward primary preventive health determine whether health assessment is important in preventing disease. African Americans have a myriad of views about health and general well being. The purpose of this study is to determine the relationship between primary preventive health knowledge, primary preventive health attitudes and primary preventive health behavior in African American undergraduate students. A survey will be …

Evaluation Of The Success Of Adoptive Versus Passive Transfer Of Immunity Against Trypanosoma Cruzi, Karen Powell

Masters Theses & Specialist Projects

Several investigators have demonstrated an increased resistance to the protozoal parasite Trypanosoma cruzi (the causative agent of Chagas' disease) in highly susceptible C3H mice when maintained at an environmental temperature of 36°C. This increased resistance is manifested as delay in onset of parasitemia, decreased parasitemia, decreased pathology, and increased longevity with eventual clearing of the parasite from the bloodstream. In addition, this enhanced resistance has been shown to be an immunologic phenomenon and not due to the direct effects of elevated temperature on the parasite itself. To ascertain the possible contributions of humoral vs. cellular immunity to the above phenomenon, …

Na/K-Atpase-Mediated 86rb+ Uptake And Asymmetrical Trophectoderm Localization Of Alpha1 And Alpha3 Na/K-Atpase Isoforms During Bovine Preattachment Development., D H Betts, L C Barcroft, A J Watson

Obstetrics & Gynaecology Publications

This study evaluated Na/K-ATPase alpha 1- and alpha 3-subunit isoform polypeptide expression and localization during bovine preattachment development. Na/K-ATPase cation transport activity from the one-cell to blastocyst stage was also determined by measuring ouabain-sensitive 86Rb+ uptake. Both alpha1- and alpha 3-subunit polypeptides were detected by immunofluorescence to encircle the entire cell margins of each blastomere of inseminated zygotes, cleavage stage embryos, and morulae. Immunofluorescent localization of alpha1-subunit polypeptide in bovine blastocysts revealed an alpha1 immunofluorescence signal confined to the basolateral membrane margins of the trophectoderm and encircling the cell periphery of each inner cell mass (ICM) cell. In contrast, alpha …

Heterologous Complementation Reveals That Mutant Alleles Of Qsr1 Render 60s Ribosomal Subunits Unstable And Translationally Inactive, Frederick A. Dick, Bernard L. Trumpower

Dartmouth Scholarship

QSR1 is a highly conserved gene which encodes a 60S ribosomal subunit protein that is required for joining of large and small ribosomal subunits. In this report we demonstrate heterologous complementation of a yeast QSR1 deletion strain with both the human and corn homologs and show that the human and corn proteins are assembled into hybrid yeast/human and yeast/corn ribosomes. While the homologous genes complement lethality of the QSR1 deletion, they also result in a diminished growth rate. Analyses of the translation rates of ribosomes containing the human and corn proteins reveal a partial loss of function. Velocity gradient analyses …

Nudel, An Unusual Mosaic Protease Involved In Defining The Embryonic Dorsal-Ventral Axis Of Drosophila Melanogaster, Charles Chansik Hong

Yale Medicine Thesis Digital Library

Dorsal-ventral polarity of the Drosophila embryo is determined by positional information that originates outside of the embryo. This information, which is created during oogenesis by the somatic follicle cells swrounding the oocyte, is utilized following fertilization to trigger a spatially regulated serine protease cascade in the extraembryonic perivitelline space. This protease cascade, which appears to be activated only on the presumptive ventral side of the embryo, generates the ligand for the Toll transmembrane protein that polarizes the embryo by inducing ventral development.This thesis presents evidence that nudel, a gene maternally required in somatic tissue for the formation of Toll's ligand, …

Patient-Guided Investigation Of The Restoration Of Health Following Traumatic Brain Injury, Nancy Ann Carney

Dissertations and Theses

The development of emergency department medical interventions and the implementation of fast-transport trauma systems has decreased the rate of death resulting from traumatic brain injury (TBI). Without corresponding methods for long-term treatment and recovery, the prevalence of people disabled by TBI has increased, creating a growing public health problem. Investigations generated by physicians, rehabilitation programs, and social scientists, which attempt to associate standard measures of injury severity with outcome, leave unexplained variance in long-term functional status for persons with TBI.

The purpose of this investigation was to use persons with brain injury and their family members, to guide an analysis …

Quantal Mechanisms Underlying Stimulation-Induced Augmentation And Potentiation, Hong Cheng

Electronic Theses and Dissertations

Repetitive stimulation of motor nerves causes an increase in the number of packets of transmitter ("quanta") that can be released in the ensuing period. This represents a type of conditioning, in which synaptic transmission may be enhanced by prior activity. Despite many studies of this phenomenon, there have been no investigations of the quantal mechanisms underlying these events, due to the rapid changes in transmitter output and the short time periods involved. To examine this problem, a method was developed in which estimates of the quantal release parameters could be obtained over very brief periods (3 s). Conventional microelectrode techniques …

Evaluation Of The Lady Free Biotester® In Determining The Fertile Period, Richard J. Fehring, Nancy Gaska

College of Nursing Faculty Research and Publications

Small hand-held microscopes have been developed for self-observation of salivary ferning patterns to detect the fertile time of a woman’s menstrual cycle. The purpose of this study was to evaluate one such microscope, the Lady Free Biotester^®, by comparing it with the self-observation of cervical-vaginal mucus and with the self-detection of luteinizing hormone (LH) in the urine. Twelve natural family planning teachers (average age 34.6 years) observed their cervical-vaginal mucus, tested their urine for LH, and observed salivary and cervical-vaginal mucus ferning patterns (with the Lady Free Biotester) for two menstrual cycles. Data indicated that there was a …

Acculturation Of A Mexican-American Male Population And Gender Role Conflict, Gary Evan Leka

Theses and Dissertations - UTB/UTPA

This study examined the effects of different modes of acculturation upon self reported levels of gender role conflict, and explored the relationship among acculturative stress, the concepts of Machismo and Familism and gender role conflicts. Hispanic males (N = 164) from a university with an 90% Hispanic enrollment were surveyed. Low Bicultural subjects differed significantly upon the factors of restrictive emotionality and restrictive affectionate behavior between men than other modes of acculturation. Machismo was found to be significantly related to stress and conflicts with gender roles, while Familism was found to be related to two of the patterns of gender …

Influence Of Boat Density Levels On Boaters' Satisfaction At Hyrum Lake, Utah, Floyd Alma Powell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to evaluate the effects of boat density on boaters' satisfaction at Hyrum Lake State Park, Utah. The study evaluated relationships between boaters' satisfaction with their Hyrum Lake experience and density of boats at different locations on the lake and among participants in different boating activities.

The participants in this study were boaters who used Hyrum Lake between May and September of 1996. An oral, on-site interview survey was randomly given to 282 boaters as they left the lake for the day. The surveys were conducted on high-density days (weekends) and low-density days (weekdays), which …

Being Alone: The Experience Of Elderly Homebound Females, Sharon Davis Burt Dnsc, Msn, Rn

Dissertations

Elderly women comprise one of the fastest growing segments of the population in the United States. This growth is due in large part to increasing longevity, and a woman's life expectancy has now reached 79 years. However, along with those added years comes an increase in morbidity and a greater likelihood of living alone. This study describes the life experience of a specific group of elderly women, those who are homebound and living alone. When elderly women are included in research, the same combination of descriptors used for the participants in this study has not been incorporated. Consequently, while much …

The Journey Through Perspective Transformation: Learning Nursing Theory, Judith R. Heggie Dnsc, Ms, Rn

Dissertations

Through the use of grounded theory, educational methods most useful for nurses to achieve a perspective transformation, as exemplified by learning nursing theory were examined. Perspective transformation is a theory originally developed by Mezirow (1978) in a study of older women returning to college for additional education. Mezirow defined perspective transformation as the alteration or change of meaning perspectives. Perspective transformation in an individual can be compared to a paradigm change within a scientific community. Within the nursing literature on perspective transformation, most articles related to the perspective transformation needed for nurses to learn to use nursing theory as the …

The Experience Of Decision-Making Among Telephone Advice/Triage Nurses, Ann Mayo Dnsc, Msn, Rn

Dissertations

The role of the telephone advice/triage nurse is both complex and demanding. All decisions are made while assessing patients without seeing or touching patients. In addition, the role is often developed to decrease health care costs which can be perceived by nurses as being in conflict with their nursing beliefs. The ambiguous nature of the role makes these nurses' daily experiences with decision-making a challenge. Using a phenomenological method, the lived experience of decision-making among telephone advice/triage nurses was explored by conducting multiple interviews with ten nurses. The internal structure of the lived experience was identified through the philosophical perspective …

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 …

Effects Of Zinc On Glucose-6-Phosphate Dehydrogenase In Buffalo Rat Liver Cells, Bryan G. Sauer

Honors Theses

In recent years, interest has surfaced in the use of insulin-mimicking agents for diabetic therapies. Zinc has been shown to have insulin-like effects in vivo and in vitro but has never been studied for its ability to mimic insulin in the regulation of carbohydrate and fatty acid metabolism. Therefore, the author studied the effects of zinc on glucose-6-phosphate dehydrogenase (G6PDH), an enzyme stimulated by insulin that is imperative in both carbohydrate and fatty acid metabolism. Because G6PDH is highly regulated in liver cells, a stable rat liver cell line, Buffalo Rat Liver (BRL), was used. Endogenous G6PDH activity and G6PDH …

The Sequential Role Of Lymphotoxin And B Cells In The Development Of Splenic Follicles, Mercedes Gonzalez, Fabienne Mackay, Jeffrey L. Browning, Marie H. Kosco-Vilbois, Randolph J. Noelle

Dartmouth Scholarship

The transfer of lymphocytes into severe combined immunodeficiency (SCID) mice induces a series of histological changes in the spleen, including the appearance of mature follicular dendritic cells (FDCs). Studies were undertaken to clarify the role of lymphotoxin (LT) in this process. The results show that SCID mice have a small and partially differentiated white pulp containing marginal zone and interdigitating dendritic cells, but lacking FDCs. Transferred spleen cells can segregate into T and B cell areas shortly after their injection to SCID mice. This ability is dependent on signaling through LT-β receptor (LT-βR), since blocking ligand–receptor interaction in recipient SCID …
