Self-Regulation Theory And Self-Monitoring Of Blood Glucose Behavior In Type 2 Diabetes Mellitus., Jennifer E. F. Ward
Self-Regulation Theory And Self-Monitoring Of Blood Glucose Behavior In Type 2 Diabetes Mellitus., Jennifer E. F. Ward
Electronic Theses and Dissertations
The present study examined self-monitoring of blood glucose (SMBG) as part of a selfregulatory process of health decision-making using the Self-Regulation Model of illness perceptions, or Common Sense Model. Participants were N=185 individuals with type 2 diabetes from a specialty diabetes clinic prescribed subcutaneous insulin or other injectable diabetes medication at least daily. Collected information included both medical chart data and self-report questionnaires completed prior receiving lab results. Self-care burden was generally high; the modal prescribed times per day of injecting insulin was 4 with modal SMBG recommendations of 3-4 times per day. Participants reported high adherence to prescribed medication …
Development Of A Thin-Film Porous-Microelectrode Array (P-Mea) For Electrical Stimulation Of Engineered Cardiac Tissue., Hiren Vrajlal Trada 1977-
Development Of A Thin-Film Porous-Microelectrode Array (P-Mea) For Electrical Stimulation Of Engineered Cardiac Tissue., Hiren Vrajlal Trada 1977-
Electronic Theses and Dissertations
Electrical stimulation has been increasingly used by research groups to enhance and increase maturation of cells in an engineered cardiac tissue (ECT). Current methods are based on using off-the-shelf wires or electrodes to deliver a stimulus voltage to the in-vitro tissue in culture medium. A major issue with this approach is the generation of byproducts in the medium due to the voltage levels required, which are typically in the range of 5V-10V. No solution currently exists that can accomplish electrical stimulation of cells in an ECT at a low voltage level. Therefore, in this study a novel, porous, thinfilm, microelectrode …
Boundary Contour Based Surface Representation., Yong Su
Boundary Contour Based Surface Representation., Yong Su
Electronic Theses and Dissertations
We receive most information about our surrounding space and objects through the eyes. To reconstruct the 3D space and objects in the visual system from the 2D retinal images, surface representation must be a critical intermediate stage in the visual processing stream. It is hypothesized in the dissertation that the visual system represents textured surface by a border-to-interior strategy: boundary contours would be encoded first and then border-ownership assignments would be resolved. This process would solve the related problems such as figure-ground segregation, surface depth relationship, occlusion, transparency, etc. As a result, the boundary contours of the surfaces would be …
The Effect Of Spinal Cord Injury On Vagal Afferents., April N. Herrity
The Effect Of Spinal Cord Injury On Vagal Afferents., April N. Herrity
Electronic Theses and Dissertations
Spinal cord injury (SCI) is a significant public health concern that leaves patients with a multitude of life-long disabilities. Major complications of SCI apart from paralysis, include deficits in bladder and bowel function. Lower urinary tract dysfunction continues to remain a top priority issue affecting quality of life for this population. The majority of visceral organs receive a dual sensory innervation from both spinal nerves as well as the vagus nerve. Following SCI, the vagus nerve is a potential pathway through which information from regions below the level of a spinal injury can travel directly to the brainstem, bypassing the …
The Impact Of Inflammatory And Immune Response-Related Genetic Variants On Prostate Cancer Risk Among Men Of African Descent., Dominique Zilpha Jones
The Impact Of Inflammatory And Immune Response-Related Genetic Variants On Prostate Cancer Risk Among Men Of African Descent., Dominique Zilpha Jones
Electronic Theses and Dissertations
Background: In the U.S., prostate cancer (PCA) metastasis is associated with a 5-yr survival rate of 29% and disproportionately affects men of African descent. Single nucleotide polymorphisms (SNPs) may serve as genetic markers to identify individuals at high risk of developing PCA. Methods: We examined main and joint effects of 119 inflammatory and immune response-associated SNPs among men of African descent (535 controls, 279 cases) via logistic regression (LR) and entropy-based-multi-factor dimensionality reduction (MDR) modeling. Results: MDR yielded highly synergistic [(TLR10, TLR6 and IRF3), (TLR2, IRAK4), (IL1R2, IL10, IL10RA)] interaction …
An Examination Of The Relationship Between Sense Of Coherence, Engagement In Health Behaviors, And Individual Coping Style., Dean Todd Misener 1973-
An Examination Of The Relationship Between Sense Of Coherence, Engagement In Health Behaviors, And Individual Coping Style., Dean Todd Misener 1973-
Electronic Theses and Dissertations
Stress is a pervasive issue among traditional college students; affecting their choice in health behaviors, and overall academic performance. What is not clear is why some students, despite the pervasiveness of stressors are able to do well in school and maintain/improve their health, while other students struggle to maintain their health and do poorly in school. Aaron Antonovsky theorized that when confronted with a stressor a person with a high sense of coherence (SOC) will be motivated to cope, believe the challenge is understood and that the necessary resources to cope with the stressor are available. Overall, Antonovsky theorized that …
Biomarker Discovery Of Liver Diseases Using Mass Spectrometry-Based Metabolomics., Xue Shi
Biomarker Discovery Of Liver Diseases Using Mass Spectrometry-Based Metabolomics., Xue Shi
Electronic Theses and Dissertations
Metabolomics has emerged as one of the latest of the "-omics" disciplines that can detect metabolite biomarkers in biological samples. The diverse characteristics of metabolites make the analytical platform challenging in metabolomics. Two bioanalytical platforms were developed in this study to investigate metabolite abundance changes under different biological conditions. We first developed a bioanalytical platform that coupled linear trap quadruple - Fourier transform ion cyclotron mass spectrometer (LTQ-FTICR MS) with direct infusion chip-based nano-electrospray ionization (DI-nESI) and applied it to study polychlorinated biphenyls (PCB) effects on non-alcoholic fatty liver disease (NAFLD). We also employed this platform in conjunction with in …
Shape/Image Registration For Medical Imaging : Novel Algorithms And Applications., Ahmed Magdy Shalaby 1982-
Shape/Image Registration For Medical Imaging : Novel Algorithms And Applications., Ahmed Magdy Shalaby 1982-
Electronic Theses and Dissertations
This dissertation looks at two different categories of the registration approaches: Shape registration, and Image registration. It also considers the applications of these approaches into the medical imaging field. Shape registration is an important problem in computer vision, computer graphics and medical imaging. It has been handled in different manners in many applications like shapebased segmentation, shape recognition, and tracking. Image registration is the process of overlaying two or more images of the same scene taken at different times, from different viewpoints, and/or by different sensors. Many image processing applications like remote sensing, fusion of medical images, and computer-aided surgery …
Modulation Of The Ovarian Cancer Humoral Response By Tumor-Derived Exosomes., Carolyn Denise Roberson
Modulation Of The Ovarian Cancer Humoral Response By Tumor-Derived Exosomes., Carolyn Denise Roberson
Electronic Theses and Dissertations
The pathogenesis of epithelial ovarian cancer is complicated by its diagnosis during the latter stages of the disease resulting from lack of symptoms or from presence of symptoms that mimic other conditions. Because of the often fatal prognosis by the time of actual detection, efforts are being made to better understand the host immune response to ovarian cancer. In this study, the contributions of the humoral immune response were investigated by focusing on the role of tumor-derived exosomes and their ability to modulate humoral immune responses. First, ovarian cancer patient-derived free circulating antibodies were investigated for immunoreactivity to patient antigen. …
Retinal Synaptic Function In The Absence Of The On Pathway., Kathryn Marie Heath Fransen
Retinal Synaptic Function In The Absence Of The On Pathway., Kathryn Marie Heath Fransen
Electronic Theses and Dissertations
Complete Congenital Stationary Night Blindness (cCSNB) is a rare hereditary retinal disorder characterized by abnormal night vision. cCSNB is caused by postsynaptic defects in On bipolar cells (BCs) and is identified by the presence of an electroretinogram (ERG) with a normal a-wave, corresponding to photoreceptor function, and the absence of a b-wave, corresponding to a failure of On BC function. Through the study of genetic mutations in mouse that result in no b-wave ERG phenotypes, several proteins have been identified that play crucial roles in On BC signal transmission. I focused on four mouse models of cCSNB; Nyxnob (Nyctalopin mutant), …
