  • Effect of GLP-1 Receptor Agonism After Sleeve Gastrectomy Rochester, MN

    Observational studies suggest that bariatric surgery is the most effective intervention for weight loss. Comparative effectiveness of Roux-en-Y Gastric Bypass (RYGB) and Sleeve Gastrectomy (SG) demonstrate that RYGB is significantly superior to SG in terms of weight loss and glycemic control. Both RYGB and SG increase GLP-1 concentrations which directly affect B-cell function. Data has shown that the postprandial rise in GLP-1 might affect feeding behavior after RYGB and to a lesser extent SG, where the increase in GLP-1 is less marked. In this study the investigators propose to randomize subjects undergoing SG to receive either placebo or Liraglutide, a ...

  • Leptin Biology in Adipose Tissue Rochester, MN

    Leptin is a fat hormone which acts in maintaining energy balance. However, leptin levels are high in obese subjects indicating resistance to the actions of leptin.

  • A Study to Evaluate the Effects of Niacin on FFA in UBO and T2DM in Insulin Resistant States Rochester, MN

    Muscle insulin resistance is a hallmark of upper body obesity (UBO) and Type 2 diabetes (T2DM). It is unknown whether muscle free fatty acid (FFA) availability or intramyocellular fatty acid trafficking is responsible for the abnormal response to insulin. Likewise, we do not understand to what extent the incorporation of FFA into ceramides or diacylglycerols (DG) affect insulin signaling and muscle glucose uptake. We will measure muscle FFA storage into intramyocellular triglyceride, intramyocellular fatty acid trafficking, activation of the insulin signaling pathway and glucose disposal rates under both saline control (high overnight FFA) and after an overnight infusion of intravenous ...

  • Muscle Metabolism Characteristics Related to Diabetes-Related Conditions Rochester, MN

    Muscle insulin resistance is a hallmark of upper body obesity (UBO) and Type 2 diabetes (T2DM), whereas lower body obesity (LBO) is characterized by near-normal insulin sensitivity. It is unknown whether muscle free fatty acid (FFA) availability or intramyocellular fatty acid trafficking differs between different obesity phenotypes. Likewise, we do not understand to what extent the incorporation of FFA into ceramides or diacylglycerols (DG) affect insulin signaling and muscle glucose uptake. By measuring muscle FFA storage into intramyocellular triglyceride, intramyocellular fatty acid trafficking, activation of the insulin signaling pathway and glucose disposal rates we will provide the first integrated examination ...

  • A Study to Evaluate Molecular Mechanisms of Exercise Benefits in Insulin Resistant People Rochester, MN

    The aim of the study is to investigate the effects of a 3-month resistance exercise program (in people aged 50 to 75) on muscle mass, body composition, muscle strength, brain function and cognition, muscle efficiency processing blood sugar, the body’s ability to build muscle, and fat cells.

    Earlier research has shown that exercise has significant benefits in preventing certain diseases and conditions such as diabetes, dementia, heart disease, and more. We also know from other research that resistance exercise (lifting weights) and aerobic exercise (running, biking, walking), improve metabolism through separate ways on the molecular level, also called “molecular pathways.” With ...

  • Dietary Sugar Absorptive Phenotype for Prediction of Weight Loss Outcome Jacksonville, FL

    Using stem cell derived intestinal epithelial cultures (enteroids) derived from obese (BMI> 30) patients and non-obese and metabolically normal patients (either post-bariatric surgery (BS) or BS-naïve with BMI < 25), dietary glucose absorption was measured. We identified that enteroids from obese patients were characterized by glucose hyper-absorption (~ 5 fold) compared to non-obese patients. Significant upregulation of major intestinal sugar transporters, including SGLT1, GLU2 and GLUT5 was responsible for hyper-absorptive phenotype and their pharmacologic inhibition significantly decreased glucose absorption. Importantly, we observed that enteroids from post-BS non-obese patients exhibited low dietary glucose absorption, indicating that altered glucose absorption ...

  • Fat Biology, Sleep Disorders, and Cardiovascular Disease Rochester, MN

    Endothelial dysfunction, or abnormal functioning of the lining of blood vessels, appears to be a key process in the development of cardiovascular disease. Endothelial dysfunction appears to be caused by both sleep disordered breathing and obesity. As endothelial dysfunction is among the first clinical marker that predicts future cardiovascular events, understanding molecular mechanisms leading to impairment of endothelial function is very important. Endothelial function requires the proper functioning of endothelial nitric oxide synthase (eNOS). eNOS activity is tightly regulated by caveolin-1, a protein important in the formation of cellular structures called caveolae. Low levels of caveolin-1 facilitate optimal nitric oxide ...

  • Intramyocellular Fatty Acid Trafficking in Insulin Resistance States - Effects of Intestinal Delivery of Lipids Rochester, MN

    Muscle insulin resistance is a hallmark of upper body obesity (UBO) and Type 2 diabetes (T2DM). It is unknown whether muscle free fatty acid (FFA) availability or intramyocellular fatty acid trafficking is responsible for muscle insulin resistance, although it has been shown that raising FFA with Intralipid can cause muscle insulin resistance within 4 hours. We do not understand to what extent the incorporation of FFA into ceramides or diacylglycerols (DG) affect insulin signaling and muscle glucose uptake. We propose to alter the profile and concentrations of FFA of healthy, non-obese adults using an overnight, intra-duodenal palm oil infusion vs. ...

  • Transforming Non-Invasive Liver Disease Detection by Magnetic Resonance Elastography Rochester, MN

    A variety of liver insults lead to pathological changes in liver architecture that culminate in cirrhosis. While invasive liver biopsy was required to detect cirrhosis, the development of magnetic resonance elastography (MRE) has revolutionized our ability to detect liver fibrosis through non-invasive means that involve measurement of liver stiffness. However, a number of pathological findings occur in liver in response to various insults that precede cirrhosis and are clinically important to identify such as steatosis associated with NASH, inflammation associated with viral hepatitis, and congestion associated with cardiac hepatopathy. Detection of such entities provides essential diagnostic, prognostic, and treatment information ...
