Effect Of Combined Oral Contraceptives On Insulin Clearance In Lean And Obese Pre-Menopausal Women, Vidya Moorthy

Theses and Dissertations

Introduction: Obese women are predisposed to greater risks of insulin resistance and compensatory hyperinsulinemia. Likewise, African-Americans, appear to be inherently insulin resistant and hyperinsulinemic even after controlling for obesity. Hyperinsulinemia has been attributed to insulin resistance and a compensatory insulin hyper-secretion by the pancreas, as well as decreased insulin clearance, notably in obesity. Pharmacological agents that may worsen insulin resistance/hyperinsulinemia in obese women is of clinical relevance. Previous data from our group suggested that combined oral contraceptives (COCs) may worsen insulin sensitivity particularly in obese women, but limited information on insulin clearance is available in obese women or African-American women. …

Biomedical and Pharmaceutical Sciences Faculty Publications

In this study we characterized the pharmacological selectivity and physiological actions of a new arylaspartate glutamate transporter blocker, L-threo-beta-benzylaspartate (L-TBA). At concentrations up to 100 mu M, L-TBA did not act as an AMPA receptor (AMPAR) or NMDA receptor (NMDAR) agonist or antagonist when applied to outside-out patches from mouse hippocampal CA1 pyramidal neurons. L-TBA had no effect on the amplitude of field excitatory postsynaptic potentials (fEPSPs) recorded at the Schaffer collateral-CA1 pyramidal cell synapse. Excitatory postsynaptic currents (EPSCs) in CA1 pyramidal neurons were unaffected by L-TBA in the presence of physiological extracellular Mg(2+) concentrations, but in Mg(2+)-free solution, EPSCs …

Nutrition Support In Acute Kidney Injury, Jane M. Gervasio, Wesley P. Garmon, Michael Holowatyj

Scholarship and Professional Work – COPHS

Acute kidney injury is a frequent complication affecting many hospitalized patients and is associated with increased morbidity and mortality. Acute kidney injury often occurs in conjunction with critical illness, which is a hypermetabolic state presenting with hyperglycemia, insulin resistance, hypertriglyceridemia, and increased protein catabolism. In addition to addressing these changes, the clinician should evaluate the important nutrition implications of decreased kidney function. These include vitamins, electrolytes, minerals, trace elements, and the presence and type of renal replacement therapy. Optimal nutrition management in acute kidney injury includes providing adequate macronutrient support to correct underlying conditions and prevent ongoing loss, supplementing micronutrients …

Analysis And Fingerprinting Of Glycosaminoglycans, Joseph King

Theses and Dissertations

Heparin is a complex mixture of sulfated polysaccharides derived from animals and one of the oldest drugs in use. While an efficacious anticoagulant, heparin is beset by side effects and pharmacokinetic difficulties. Low molecular weight heparins (LMWH) are made by depolymerizing unfractionated heparin (UFH) and present improvements in these areas. However, they still retain a phenomenally high level of complexity due to their polydispersity and the introduction of non-native structural features. This makes the structural characterization LMWHs a daunting task. This work details the development of a novel capillary electrophoretic (CE) method for fingerprinting LMWHs. Since their complexity normally results …

Synthesis Of A Library Of Sulfated Small Molecules, Shrenik Mehta

Theses and Dissertations

The discovery of heparin in 1916 resulted in a huge impact on the practice of medicine. Heparin has played a major role in alleviating thrombotic disorders and has also exhibited effects on almost every major system in the human body. Over the past few decades, more and more heparin-protein interactions have come to light. It is implicated to modulate several important processes such as cell growth and differentiation, inflammatory response, viral infection mechanism etc. More interesting is the observation that these interactions are considerably specific with regard to oligosaccharide sequences which have specific spatially oriented sulfate groups modulating the responses. …
