A Pilot Study On The Short Term Effects Of The Herbst Appliance On The Glenoid Fossa, David A. Bennion

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this pilot study was to evaluate the initial effects of the Herbst appliance and determine through the use of common cephalometric radiographs that were optically enhanced and then digitally reproduced, if fossa migration is taking place. Fourteen, (6 male, 8 female), growing patients were treated by the same clinician for the correction of a Class II malocclusion using a modified Herbst appliance. Pretreatment (T₁) standard lateral cephalometric radiographs and post Herbst treatment (T_H) optically enhanced lateral cephalometric radiographs were taken. All radiographs were digitally captured and reproduced so 6 linear and 1 area …

Risk Factors Associated With Coronary Artery Disease In Individuals After Coronary Artery Bypass Graft Surgery, Deborah Benderman King

MSN Research Projects

Since the early 1960s coronary artery disease (CAD) has been the nation's leading killer of middle-aged men. Even with development of coronary artery bypass graft (CABG) surgery, the recurrence rate remains high. The research question addressed in this descriptive study was what risk factors associated with CAD can be identified in individuals after CABG surgery? Using Becker's Health Belief Model as a theoretical framework, a convenience sample of 69 postoperative CABG clients from a rural Mississippi cardiac rehabilitation program completed researcher-developed surveys. Descriptive analysis identified the following risk factors in the sample : Forty-three (63%) of subjects reported eating fried …

Relationship Between Selected Demographic Variables And Self-Esteem In Female Adolescents In The Rural South, Denise Tennison

MSN Research Projects

Self-esteem is recognized as a basic personality- characteristic of positive and productive behavior. The view the adolescent female has of herself is of utmost importance and may have an impact on behavior, achievement, social functioning, and physical and emotional health. The purpose of this study was to determine whether there was a relationship between sociodemographic variables and self-esteem in adolescent females. Roy's Adaptation Model was used to guide this descriptive correlation investigation. Data were collected from a sample of 3 0 adolescent females from a small rural high school in East Central Mississippi. Participants were surveyed using the Rosenberg Self-Esteem …

Coping Strategies Of Mothers With Developmentally Delayed Children Who Attend A Support Group And Who Do Not Attend A Support Group, Donna Salvo Foster

MSN Research Projects

When faced with stress, behavioral and psychological reactions occur to decrease the person's perception of the stress. Rearing a child with developmental delay is one such stressful event. The purpose of this investigation was to explore coping strategies of mothers who are rearing a child with developmental delay. Two hypotheses were generated; There will be no statistically significant differences in perceived coping strategy scores used by mothers with developmentally delayed children in a support group and those not in a support group, and there will be no statistically significant differences in perceived effectiveness of coping strategy scores used by mothers …

Incidence Of Documented Exercise Prescription In Nurse Practitioner Client With A Diagnosis Of Cardiovascular Disease, Shannon Phillips

MSN Research Projects

The purpose of this ex post facto descriptive study was to determine the incidence of documented exercise prescription in nurse practitioner clients with a diagnosis of cardiovascular disease. Pender's Health Promotion Model provided the theoretical framework for this study. Nurse practitioners providing primary care in the State of Mississippi was the target population, with four nurse practitioners providing care in clinics representing the four geographical regions of Mississippi (Northeast, Southwest, Southeast, and Northwest) selected as a nonrandom sample of convenience. At each clinic, from the total population of records in which clients were aged 25 to 65 years with a …

Effects Of An Otitis Media Prevention Program On Healthy Infants, Rena D. Matthews

MSN Research Projects

Otitis media (OM) is the leading illness among infants and children. Risk factors have been identified which increase occurrence of OM in infants. The purpose of the quasi- experimental study was to determine if teaching OM prevention to parents of healthy infants would reduce the occurrence rate of OM. The theoretical framework for the research was based on the Health Promotion Model (Pender, 1996) which focuses on the integration of health-promoting behavior into lifestyles. The research hypothesis was that there would be no statistically significant difference in the effects of an OM prevention program on healthy infants and a control …

Self-Esteem Levels Of Pregnant Adolescents From Different Races, Stephanie M. Gale

MSN Research Projects

Effective pregnancy prevention in adolescence remains elusive to researchers and health care providers. Several studies have been conducted on the relationship between self-esteem and race and between self-esteem and pregnancy in adolescent populations. The purpose of this study was to determine if a difference exists between self-esteem levels and race in pregnant adolescents. Leininger's Cultural Care Theory was the theoretical framework used in this study. The null hypothesis was there is no difference between self-esteem levels and race in pregnant adolescents. The setting for this descriptive comparison study was a prenatal clinic for underserved populations in the Southeastern United States. …

Assembly And Regulation Of The Cd40 Receptor Complex In Human B Cells, Michelle R. Kuhné, Michael Robbins, John E. Hambor, Matthew F. Mackey, Yoko Kosaka, Toshihide Nishimura, Jason P. Gigley, Randolph J. Noelle, David M. Calderhead

Dartmouth Scholarship

CD40 is a member of the tumor necrosis factor (TNF) receptor superfamily. Studies with human B cells show that the binding of CD154 (gp39, CD40L) to CD40 recruits TNF receptor– associated factor 2 (TRAF2) and TRAF3 to the receptor complex, induces the downregulation of the nonreceptor-associated TRAFs in the cell and induces an increased expression of Fas on the cell surface. Combined signaling through the interluekin 4 receptor and CD40 induces an increased expression of Fas with a commensurate increase in the level of TRAF2, but not TRAF3, that is recruited to the receptor complex. In contrast, engagement of the …

An Epidemic Of Dengue Fever In Karachi--Associated Clinical Manifestations, J A. Qureshi, N J. Notta, N Salahuddin, V Zaman, J A. Khan

Section of Internal Medicine

Dengue is a mosquito borne disease with worldwide distribution. Depending on virulence factors and host immune status, infection can manifest as a severe but non fatal viral syndrome or a rapidly progressive and a frequently fatal haemorrhagic fever. During the course of an outbreak of viral fever in Karachi, Pakistan from June, 1994 to September, 1995, we studied 145 cases admitted at the Aga Khan University Hospital. 43% of the cases were between the age group of 20-30 years, majority of these being male (75%). Amongst the clinical signs and symptoms, the most frequent findings were fever, vomiting and abdominal …

Transcranial Magnetic Stimulation Of The Prefrontal Cortex Delays Contralateral Endogenous Saccades, Tony Ro, Avishai Henik, Liana Machado, Robert D. Rafal

Publications and Research

The contributions of the superior prefrontal cortex (SPFC) and the superior parietal lobule (SPL) in generating voluntary endogenous and reflexive visually guided saccades were investigated using transcranial magnetic stimulation (TMS). Subjects made choice saccades to the left or right visual field in response to a central arrowhead (endogenous go signal) or a peripheral asterisk (exogenous go signal) that were presented along with a single TMS pulse at varying temporal intervals. TMS over the SPFC increased latencies for saccades made in response to an endogenous go signal toward the contralateral hemifield. No effects were observed when the go signal was exogenous …

Characterization Of The Fast Axonally Transported Proteins In The Rat Optic Pathway, Surafel Mulugeta

Theses and Dissertations in Biomedical Sciences

The fast axonally transported proteins represent a subset of neuronal proteins that are conveyed anterogradely as secretory vesicle constituents from the perikarya. Although fast transport displays properties consistent with the general secretory pathway, neuronal structure presents special problems which may require modifications of the general pathway. The elucidation of these special modifications is essential for a more complete understanding of neuronal function both in normal and pathological conditions. In order to characterize the fast transported (FT) proteins and to better understand fast transport trafficking, the FT of radiolabeled retinal ganglion cell (RGC) proteins in the adult rat optic pathway was …

Endothelial Nitric Oxide Synthase And Growth Factor Regulation Of Flow-Mediated Vascular Remodeling, David Anthony Tulis

Theses and Dissertations in Biomedical Sciences

This study was designed to characterize structural remodeling of male Wistar rat mesenteric arteries exposed to elevated blood flow in vivo for 1, 3, or 7 days. A series of arterial ligations induced blood flow increases in ileal and second-order branch arteries compared to same animal control vessels. Neither mean carotid nor local mesenteric arterial pressures changed significantly pre- to post-ligation. The primary flow-mediated force in both vessels was shear stress with possible involvement of acute stretch-induced wall stress in the ileal artery. Significant luminal expansion and medial wall hypertrophy occurred in the ileal and second-order arteries in a time-dependent …

The Effect Of Growth Hormone Release On Plasma And Erythrocyte Selenium And Zinc Levels In Children, Maria Estela Legal De Reid

Chemistry & Biochemistry Theses & Dissertations

Research studies have suggested that selenium may be important in the release of growth hormone, GH. A selenium-containing amino-acid residue, selenocysteine, has been identified as part of the active site of the three isoenzymes (Type I, II and III iodothyronine 5' -deiodinase) responsible for the synthesis of active thyroid hormone, T_3, which is reported to stimulate GH secretion. The importance of zinc in growth is well- documented because of its involvement in transcription and expression of GH and its intermediary, insulin growth factor I or IGF- I. Thus, selenium and zinc levels in plasma may be altered in response …

Fluorescence In Situ Hybridization Analysis Of Human Embryos Derived From In Vitro And In Vivo Matured Oocytes, Constance Descisciolo

Theses and Dissertations in Biomedical Sciences

Despite adequate hormonal stimulation, oocytes collected for the purpose of in vitro fertilization and embryo transfer display several levels of nuclear maturity. Preovulatory or mature oocytes, technically those that are Metaphase I or II, are inseminated shortly after aspiration and assessed for fertilization the following day. Prophase I oocytes, also called germinal vesicle-bearing or immature oocytes, require a 24-36 hour period in culture before being exposed to spermatozoa. During this time, the majority of Prophase I oocytes complete nuclear maturation in vitro, progressing from germinal vesicle breakdown through first polar body extrusion. If inseminated, many in vitro matured oocytes fertilize …

Interaction Of Acth And Estradiol In The Regulation Of Growth, Differentiation, And Steroidogenic Maturation Of The Baboon Fetal Adrenal Gland, Maria Gomez Leavitt

Theses and Dissertations in Biomedical Sciences

The present study determined whether the growth of, as well as ACTH receptor and P-450 enzyme messenger ribonucleic acid and/or protein levels in the baboon fetal adrenal are dependent upon fetal pituitary ACTH during mid and late gestation and the mechanism by which placental estrogen modulates ACTH actions. Administration of betamethasone (3mg/day) to baboon mothers on days 60-99 of gestation and to the fetus (0.6 mg/, n = 4) or to the fetus (0.6mg) and mother (6 mg/ml; n = 4) every other day between days 150-164 of gestation (term = 184 days) decreased (P $53β-hydroxysteroid dehydrogenase-isomerase (3β-HSD(+)ctochrome P450 17α-hydroxylase, …

The Cellular And Molecular Dynamics Of The Queuosine Modification In Transfer Rna: Definition, Modulation, Deficiencies And Effect Of The Queuosine Modification System, Rana C. Morris

Theses and Dissertations in Biomedical Sciences

The presence of the queuosine modification in the wobble position of tRNA^asn, tRN^asp, tRNA^his, and tRNA^tyr is associated with a decrease in cellular growth rate, an increase in the ability to withstand environmental stress, and differentiation of pleuripotent cells into mature phenotypes. The loss of this normal modification is strongly correlated with neoplastic transformation and tumor progression of a wide variety of cancers.

The "normal" system for formation of the queuosine modification in tRNA was studied in human fibroblast cell cultures and in mouse, rat and human liver tissues. The queuosine modification system …

Effect Of Cocaine On Rabbit Renin Angiotensin System: Cocaine Detection In Adult And Fetal Tissue And Adult Plasma Using Ion Mobility Spectrometry, Barbara Belinda Guinn

Biological Sciences Theses & Dissertations

Ion mobility spectrometry (IMS) was used to detect cocaine and/or the metabolite ecgonine methyl ester (EME) in tissue and plasma samples from male, maternal, and fetal New Zealand White (NZW) rabbits. EME was consistently detected in all adult plasma samples 5 minutes after the injection of cocaine hydrochloride (cocaine•HCI, 2 mg/kg). EME was also in the liver, kidneys, testicles, and ovaries. Five minutes after the injection of cocaine•HCI, the male arterial pressure (MAP) increased from a mean control value of 79 ± 3.2 mmHg to 88 ± 4.1 mmHg, and the pCO₂ increased from a control value of28 ± …

Regulation Of The Rat Liver Sodium-Dependent Bile Acid Cotransporter Gene By Prolactin. Mediation Of Transcriptional Activation By Stat5, Tanmoy C. Ganguly, Michelle L. O'Brien, Saul J. Karpen, James F. Hyde, Fredrick J. Suchy, Mary Vore

Toxicology and Cancer Biology Faculty Publications

The intracellular mechanism(s) underlying the upregulation of the hepatic Na+/taurocholate cotransporting polypeptide (ntcp) by prolactin (PRL) are unknown. In this report, we demonstrate a time-dependent increase in nuclear translocation of phosphorylated liver Stat5 (a member of the ignal ransducers and ctivators of ranscription family) that correlated with suckling-induced increases in serum PRL levels. In electrophoretic mobility gel shift assays, nuclear Stat5 exhibited specific DNA-binding ability towards IFN-gamma-activated sequence (GAS)-like elements (GLEs; 5'TTC/A-PyNPu-G/TAA-3') located in the -937 to -904 bp region of the ntcp promoter. Transient cotransfections in HepG2 cells revealed that PRL inducibility (2.5-3-fold) required coexpression of the long form …

The Glucose Transporter Glut4 And The Aminopeptidase Vp165 Colocalise In Tubulo-Vesicular Elements In Adipocytes And Cardiomyocytes, Sally Martin, Jacqueline E. Rice, Gwyn W. Gould, Susanna R. Keller

Dartmouth Scholarship

The aminopeptidase vp165 is one of the major polypeptides enriched in GLUT4-containing vesicles immuno-isolated from adipocytes. In the present study we have confirmed and quantified the high degree of colocalisation between GLUT4 and vp165 using double label immuno-electron microscopy on vesicles isolated from adipocytes and heart. The percentage of vp165-containing vesicles that also contained GLUT4 was 91%, 76%, and 86% in rat adipocytes, 3T3-L1 adipocytes, and rat heart, respectively. Internalisation of a transferrin/HRP (Tf/HRP) conjugate by 3T3-L1 adipocytes, followed by diaminobenzidine treatment in intact cells, resulted in ablation of only 41% and 45% of GLUT4 and vp165, respectively, whereas endosomal …

Obstetrics & Gynaecology Publications

Bovine oviductal monolayer and vesicle primary cultures express insulin-like growth factor (IGF)-I and -II mRNAs and polypeptides. Early bovine embryos also express IGF-I, IGF-II, IGF-I receptor, IGF-II receptor, and insulin receptor mRNAs. This study reports the expression of IGF binding protein (IGFBP) mRNAs and polypeptides in bovine oviduct primary cultures and IGFBP mRNAs in preattachment embryos. Release of immunoreactive IGF-I and IGF-II by oviduct cultures and bovine blastocysts was also determined. IGFBP-2, -3, -4, and -5 transcripts were observed in oviduct primary cultures throughout an 8-day interval. IGFBP-1 and -6 mRNAs were consistently not detected in the oviduct. Messenger RNAs …

Cultural, Historical, And Subcultural Contexts Of Adolescence: Implications For Health And Development, Lisa J. Crockett

Department of Psychology: Faculty Publications

Although clearly influenced by biological and psychological growth, adolescent development is also molded by the social and cultural context in which it occurs. As the transition from childhood to adulthood, adolescence is closely tied to the structure of adult society, and the expectations for youth during this period reflect, in important ways, the skills and qualities deemed important for success in adult roles (Benedict, 1937; Havighurst, 194811972). Furthermore, prevailing demographic, economic, and political conditions determine the adult occupational and social roles to which young people can aspire, as well as the access to and competition for those roles (Elder, 1975). …
