Static Vascular Modeling Of Diabetes Progression, Andrea Skattenborg
Static Vascular Modeling Of Diabetes Progression, Andrea Skattenborg
Master's Theses
Cardiovascular disease is the leading cause of mortality in diabetic patients, and diabetes is one of the main causes of cardiovascular disease. Risk factors for cardiovascular disease result in structural and functional changes in the vascular wall. Arterial stiffness is a prominent structural change observed in the arterial wall that can be measured in clinical settings. The purpose of this thesis was to create a static model of the changes in arterial stiffness seen in diabetes. Elastic tubes with varying wall thicknesses were used to create artificial arteries for this purpose. Compliance (inverse of stiffness) of the arteries was determined …
Nurses' Level Of Comfort, Familiarity, And Knowledge About Diabetes Management In Vinmec Central Park International Hospital, Nguyen Thi Xuan Mai
Nurses' Level Of Comfort, Familiarity, And Knowledge About Diabetes Management In Vinmec Central Park International Hospital, Nguyen Thi Xuan Mai
Master's Theses
Clinical nurses have a key role in supporting and management of diabetes patients during hospitalization. The purpose of this study was to evaluate nurses’ level of comfort, familiarity, and knowledge in diabetes management. In this study, 30 full-time nurses working in Vinmec Central Park International Hospital completed a 34-question assessment that included eight questions on comfort, six questions on familiarity, and 20 questions on nursing knowledge. The findings indicated the level of nursing knowledge regarding diabetes management in the hospital was low. The comfort, familiarity, and knowledge scores were not directly proportional to the age, education, and years of clinical …
Development And Characterization Of Tissue Engineered Blood Vessel Mimics Under "Diabetic" Conditions, Shelby Gabrielle Kunz
Development And Characterization Of Tissue Engineered Blood Vessel Mimics Under "Diabetic" Conditions, Shelby Gabrielle Kunz
Master's Theses
The development of tissue engineered blood vessel mimics for the testing of intravascular devices in vitro has been established in the Cal Poly tissue engineering lab. Due to the prevalence of cardiovascular disease in diabetic patients and minimal accessible studies regarding the interactions between diabetes and intravascular devices used to treat vascular disease, there is a need for the development of diabetic models that more accurately represents diabetic processes occurring in the blood vessels, primarily endothelial dysfunction. This thesis aimed to create a diabetic blood vessel mimic by implementing a high glucose environment for culturing human endothelial cells from healthy …
Postcolonialism And The Marshallese Diaspora: Structural Violence And Health In The Marshallese Community In Springdale, Arkansas, Alexander J. Hirata
Postcolonialism And The Marshallese Diaspora: Structural Violence And Health In The Marshallese Community In Springdale, Arkansas, Alexander J. Hirata
Master's Theses
Despite moving to the United States for better healthcare, among other benefits, Marshallese Compact of Free Association (COFA) migrants residing in Springdale, Arkansas continue to face similar acute health problems as Marshallese living in the Republic of the Marshall Islands (RMI), and often without access to health services. These problems include high rates of noncommunicable diseases, such as type 2 diabetes and thyroid cancer, as well as rare conditions such as Hansen’s Disease.
To research this, I studied the limited texts surrounding the Marshallese diaspora, as well as relevant bodies of literature: postcolonialism, Pacific migration theory, and global health and …
Determination Of The Molecular Mechanisms Of Hyperglycemia-Induced Changes In Cav3.2 Calcium Channel Properties, Ginny Marie Keeling
Determination Of The Molecular Mechanisms Of Hyperglycemia-Induced Changes In Cav3.2 Calcium Channel Properties, Ginny Marie Keeling
Master's Theses
Hyperglycemia can cause altered excitability due to increased CaV3.2 T-type calcium channel function, bestowing diabetics an increased neuropathy risk. The objective of this study was to understand the molecular mechanisms of increased CaV3.2 function during hyperglycemia in vitro, which leads to a 58% increase in current density and increased channel open probability (PO), among other changes. Two major findings are reported in this study:
1) The enzymatic elimination of extracellular N-acetylneuraminic acid (NANA) moieties reversed the increase in current density and the shift in PO, showing that hyper-glycosylation alters channel function in disease.
2) Treatment with GM1 (a ganglioside highly …
Glucose Biosensor Using Electrospun Mn2o3-Ag Nanofibers, Shan Huang
Glucose Biosensor Using Electrospun Mn2o3-Ag Nanofibers, Shan Huang
Master's Theses
The highly porous Mn2O3-Ag nanofibers were fabricated by a facile two-step procedure (electrospinning and calcination) and then employed as the immobilization matrix for glucose oxidase (GOD) to construct an amperometric glucose biosensor. A notable enhancement of direct electron transfer between GOD and the electrode is observed at the Mn2O3-Ag-GOD modified electrode with a fast electron transfer rate constant. The biosensor also shows fast response to glucose, high sensitivity (40.60 μA×mM-1×cm-2), low detection limit (1.73 µM at S/N=3), low Km,app value and excellent selectivity. These results indicate that …
Implementation And Assessment Of Hyperglycemic Conditions For The Creation Of A Diabetic Blood Vessel Mimic, Vikramaditya Mediratta
Implementation And Assessment Of Hyperglycemic Conditions For The Creation Of A Diabetic Blood Vessel Mimic, Vikramaditya Mediratta
Master's Theses
Introduction: Diabetes Mellitus is a metabolic disorder that affects a person’s ability to either produce insulin (Type I diabetes mellitus) or properly use insulin (Type II diabetes mellitus) in order to maintain adequate blood glucose levels. The most severe diabetic complications arise due to hyperglycemia – a state of extremely high blood glucose levels – such as, coronary artery disease (CAD), in which coronary stent therapy is a popular method of treatment. However, research has shown a high rate of in-stent restenosis in diabetic patients with CAD, most likely due to activation of cellular adhesion molecules on endothelial cells exposed …
Synthesis Of Hybrid Inositol Glycan Analogues, Smita Fulzele
Synthesis Of Hybrid Inositol Glycan Analogues, Smita Fulzele
Master's Theses
Inositol glycans (IGs) are small oligosaccharides exhibiting insulin-like metabolic activities in insulin-sensitive cells. The signal transduction pathways activated by IGs in these cells are still under study, but it is known that there is cross talk between the IG-signaling pathway and the insulin-signaling pathway downstream of the insulin receptor. Therefore, IGs may have potential for use in the treatment of type II diabetes mellitus. However, natural IGs are heterogeneous and difficult to isolate. Hence, synthetic IGs and their analogues have been chemically synthesized and evaluated for insulin-mimetic properties by various research groups. Unfortunately, the most biologically active IG analogues are …
