Perceived Deprivation In Active Duty Military Nurse Anesthetists, Julie Ann Pearson

Theses and Dissertations

Problem: There is a shortage of military certified registered nurse anesthetists (CRNAs). The exodus from military service to civilian careers could be a result of relative deprivation (the discrepancy that one perceives between what one has and what one could or should have). Relative deprivation is a perception of unfairness dependent on feelings (subjective data) as well as facts (objective data). Purpose: The purpose of this study was to measure relative deprivation in active duty military nurse anesthetists, to explore variables which correlate with relative deprivation, and to validate or refute the theory of relative deprivation in active duty military …

M. Leprae Inhibits Apoptosis In Thp-1 Cells By Downregulation Of Bad And Bak And Upregulation Of Mcl-1 Gene Expression, Zahra Hasan, Mussarat Ashraf, Ali Tayyebi, Rabia Hussain

Department of Pathology and Laboratory Medicine

Background: Virulent Mycobacterium leprae interfere with host defense mechanisms such as cytokine activation and apoptosis. The mitochondrial pathway of apoptosis is regulated by the Bcl-2 family of proteins. Expression of Fas ligand and apoptotic proteins is found in leprosy lesions and M. leprae has been shown to activate pro-apoptotic Bcl-2 genes, Bak and Bax. However, the mechanism by which M. leprae modulates apoptosis is as yet unclear. We investigated expression of apoptotic genes in THP-1 monocytes in response to infection by M. leprae and non-pathogenic M. bovis BCG.

Extra Pulmonary Uptake Of Tc-99m-Maa Perfusion Lung Scan As A Result Of Right To Left Intra Cardiac Shunt, Riffat Hussain, Maseeh-Uz-Zaman, Sohail Abrar Khan, M Nadeem Ahmad Jan 2006

Extra Pulmonary Uptake Of Tc-99m-Maa Perfusion Lung Scan As A Result Of Right To Left Intra Cardiac Shunt, Riffat Hussain, Maseeh-Uz-Zaman, Sohail Abrar Khan, M Nadeem Ahmad

Department of Pathology and Laboratory Medicine

Extra pulmonary accumulation of Tc-99m-macroaggregate of albumin (MAA) is rarely seen on perfusion lung scan, and has been reported in less than 4% of a study population of nearly 380 patients1. It occurs when the agent bypasses the lungs due to a right to left (R-L) cardiac or pulmonary shunt, when it is shunted to the portal vein before reaching the right atrium and ventricle of the heart, and when the agent is degraded to a submicron particle size.2 When a pharmaceutical problem is excluded, extra-pulmonary uptake implies unusual hemodynamics with a shunt.

The Use Of Proteomic Technologies To Identify Serum Glycoproteins For The Early Detection Of Liver And Prostate Cancers, Elizabeth Ellen Schwegler Jan 2006

The Use Of Proteomic Technologies To Identify Serum Glycoproteins For The Early Detection Of Liver And Prostate Cancers, Elizabeth Ellen Schwegler

Theses and Dissertations in Biomedical Sciences

The application of proteomic technologies to identify serum glycoproteins is an emerging technique to identify new biomarkers indicative of disease severity. Many of these newly evolving protein-profiling methodologies have evolved from previous global protein expression profiling studies such as those involving SELDI-TOF-MS technologies. Though the SELDI approach could distinguish disease from normal by utilizing protein patterns as shown herein with the HCC study of chapter II, it was unable to offer sequence information on the selected peaks, and did not have the ability to analyze the entire dynamic range of the serum/plasma proteome. To address these deficiencies, new strategies that …


Understanding The Nature Of Surgical Excellence Using A Competency Modeling Approach, Hope S. Hanner-Bailey Jan 2006

Understanding The Nature Of Surgical Excellence Using A Competency Modeling Approach, Hope S. Hanner-Bailey

Psychology Theses & Dissertations

Currently, a thorough description of the knowledge, skills, abilities, and other personal characteristics (KSAOs) that distinguish an exceptional surgeon does not exist. This knowledge is pertinent to the development of selection, training, and performance assessment methods that can be used to develop high performing surgeons. Expert surgeons from around the country were recruited to participate in an interview to discuss the KSAOs (i.e., the competencies) needed to be exceptional in the field. A smaller number of novice surgeons were also interviewed. The expert interview data were distilled into a competency model that consists of ten competencies and patterns within the …

Placental Expression Of Angiopoietin-1, Angiopoietin-2 And Tie-2 During Placental Development In An Ovine Model Of Placental Insufficiency-Fetal Growth Restriction., Amy S Erickson Hagen, Ryan J Orbus, Randall B Wilkening, Timothy Regnault, Russell V Anthony

Paediatrics Publications

Fetal growth restriction (FGR) is associated with increased perinatal morbidity and mortality, and often results from functional placental insufficiency. Placentation requires extensive vasculogenesis and subsequent angiogenesis, in both maternal and fetal tissues. Angiopoietin-1 (Ang-1) and Angiopoietin-2 (Ang-2) are angiogenic growth factors expressed in the placenta, and compete for binding to a common receptor, Tunica interna endothelial cell kinase-2 (Tie-2). Our objective was to examine Ang-1, Ang-2 and Tie-2 expression in ovine placental tissue obtained from normal and FGR pregnancies throughout gestation. Fetal cotyledon and maternal caruncle tissue concentrations of Ang-1, Ang-2 and Tie-2 mRNA were assessed by real-time reverse transcriptase-polymerase …

Obstetrics and Gynaecology, East Africa

Background: The microbiological diagnosis of bacterial vaginosis is usually made using Nugent's criteria, a useful but rather laborious scoring system based on counting bacterial cell types on Gram stained slides of vaginal smears. Ison and Hay have simplified the score system to three categories and added a fourth category for microflora with a predominance of the Streptococcus cell type. Because in the Nugent system several cell types are not taken into account for a final score, we carried out a detailed assessment of the composition of the vaginal microflora in relation to standard Gram stain in order the improve the …

A Case Of Transient Diabetes Insipidus Following Cardiopulmonary Bypass, Omer Ashraf, Hasanat Sharif, Mansoor Shah

Section of Cardiothoracic Surgery

Cardiopulmonary bypass surgery has been linked with a number of postoperative complications. One of the frequently reported physiological alterations is the relative diuresis seen in the immediate post-op period. Rarely reported though is the development of full-blown diabetes insipidus in such patients. The etiology is unknown and has only been hypothesized in the past. We present the clinical course of a 54 year old male who developed transient diabetes insipidus post bypass surgery with subsequent recovery following exogenous vasopressin administration. The physiological alteration leading to the development of diabetes insipidus in a small fraction of bypass patients remains unknown. We …

Mechanisms Of Hbo-Induced Neuroprotection In A Neonatal Hypoxia-Ischemia Model, John Winter Calvert Dec 2005

Mechanisms Of Hbo-Induced Neuroprotection In A Neonatal Hypoxia-Ischemia Model, John Winter Calvert

Loma Linda University Electronic Theses, Dissertations & Projects

With an incidence approaching 1/4000 live births and as high as 60% in low birth weight infants, cerebral hypoxia-ischemia during the perinatal period is the single most important cause of acute mortality and chronic disability in newborns. Herein, we tested the hypothesis that following a hypoxic-ischemic insult hyperbaric oxygen (HBO) treatment can restore high energy metabolite levels in the affected regions of the brain and through this increase in energy levels ameliorate the spread of cell death following the insult. We also investigated if an additional mechanism by which HBO affords its neuroprotection is by altering the expression of the …
