Insulin Dynamics In African Americans And European Americans: Mechanistic Aspects, And Association With Inflammation, Radhika P. Phadke
Insulin Dynamics In African Americans And European Americans: Mechanistic Aspects, And Association With Inflammation, Radhika P. Phadke
All ETDs from UAB
Identification and characterization of ethnic differences in insulin dynamics, insulin sensitivity (SI), and inflammation may shed light on the greater risk for type 2 diabetes in African Americans (AA), relative to European Americans (EA). Ideally, such studies should take into account the potential confounding roles of adiposity, fat distribution, genetic background, and socioeconomic status (SES). The objectives of this study were, 1) to evaluate ethnic differences in insulin dynamics in AA and EA children and adults using robust measures of insulin secretion and clearance; 2) to identify the contributions of genetic admixture and SES to insulin dynamics; 3) to examine …
Ethnic Differences In Markers Of Inflammation With Weight Loss, Tanya C. Hyatt
Ethnic Differences In Markers Of Inflammation With Weight Loss, Tanya C. Hyatt
All ETDs from UAB
Chronic diseases such as type 2 Diabetes Mellitis (T2DM) and cardiovascular disease (CVD) are accompanied by chronic low-grade systemic inflammation and are related to obesity and ethnicity. For instance, African-Americans (AA) have increased risk for developing T2DM and are more likely to be overweight relative to Caucasians (C). However, C have more intra-abdominal adipose tissue (IAAT) and have higher risk for CVD than AA. The influence that ethnicity has on disease risk is obscured by ethnic differences in fat distribution and sensitivity to insulin. Ethnic differences in markers of inflammation (MOI) have not been investigated. It is also unclear if …
Determinants Of Hospital Affiliation With Health Care Networks, Ting-Huan Chang
Determinants Of Hospital Affiliation With Health Care Networks, Ting-Huan Chang
All ETDs from UAB
Since the 1990s, integrated health care delivery systems have proliferated rapidly in the U.S., but little research has been devoted to studying why hospitals decide to join such systems (e.g., health care networks or systems). The aim of this study was to identify environmental and organizational factors that encourage freestanding hospitals to affiliate with health care networks. Specifically, the relationships of hospital affiliation choice to environmental munificence, environmental uncertainty and organizational resources were examined. Additionally, the moderating effects of hospital setting on these relationships were also investigated. A nonexperimental, longitudinal design was used, with the individual hospital as the unit …
Factors Influencing The Adoption Of Administrative Innovations, Tom J. Sanders
Factors Influencing The Adoption Of Administrative Innovations, Tom J. Sanders
All ETDs from UAB
The purpose of this dissertation was to investigate the influence of selected environmental and organizational factors on the adoption of administrative innovations in order to better understand strategic adaptation by organizations. General systems theory, various organizational theories, strategic adaptation and management theories, and adoption and diffusion of innovation literature were used to develop a theoretical framework to address four primary and sixteen secondary hypotheses. The administrative innovation used for this study was the magnet hospital concept for enhancing attraction and retention of registered nurses in order to address a persistent workforce shortage in U.S. hospitals. Secondary data related to U.S. …
Importance Of Trnalys,3 Structure And Use In Gag Translation For Primer Selection Required For Replication Of Human Immunodeficiency Virus Type I, Wanfeng Yu
All ETDs from UAB
The features of tRNALys,3 that dictate why human immunodeficiency virus exclu-sively selects this tRNA as the primer for initiation of reverse transcription is unknown. The post-transcriptional modification at nucleotide 58 in the TΨC stem-loop could play a role during plus-strand synthesis to stop reverse transcriptase from re-copying the tRNA primer. Nucleotides 53 and 54 within the TΨC stem loop of the tRNA have been shown to be important to form the complex between tRNA and the HIV-1 viral genome during initiation of reverse transcription. To further delineate the features of the TΨC stem loop in tRNALys,3 in reverse transcription, we …
