Exercise can increase skeletal muscle sensitivity to insulin, improve insulin resistance and regulate glucose homeostasis in rat models of type 2 diabetes. However, the potential mechanism remains poorly understood. In this study, we established a male Sprague-Dawley rat model of type 2 diabetes, with insulin resistance and β cell dysfunction, which was induced by a high-fat diet and low-dose streptozotocin to replicate the pathogenesis and metabolic characteristics of type 2 diabetes in humans. We also investigated the possible mechanism by which chronic and acute exercise improves metabolism, and the phosphorylation and expression of components of AMP-activated protein kinase (AMPK) and …

AIMS AND HYPOTHESIS: Glucose-stimulated insulin secretion from beta-cells is a tightly regulated process that requires calcium flux to trigger exocytosis of insulin-containing vesicles. Regulation of calcium handling in beta-cells remains incompletely understood. Gem, a member of the RGK (Rad/Gem/Kir) family regulates calcium channel handling in other cell types, and Gem over-expression inhibits insulin release in insulin-secreting Min6 cells. The aim of this study was to explore the role of Gem in insulin secretion. We hypothesised that Gem may regulate insulin secretion and thus affect glucose tolerance in vivo.

METHODS: Gem-deficient mice were generated and their metabolic phenotype characterised by in …

Type 2 Diabetes Science And American Indian / Alaska Native Culture: Creating A National K-12 Curriculum Prevention Strategy For Native Youth, Carolee Dodge Francis, Michelle Chino

Environmental & Global Health Faculty Research

Preventing and reducing the onset of type 2 diabetes among American Indian/Alaska Native youth requires educational strategies to affect knowledge, attitudes, and cognitive decision-making skills. In an unparalleled effort to address the growing epidemic of type 2 diabetes in tribal communities, eight tribal colleges and three federal agencies collaborated to develop and implement a kindergarten-through-twelfth-grade (K–12) Diabetes Education in Tribal Schools curriculum. This article outlines the scientific and cultural development of a comprehensive K–12 science curriculum as a targeted health prevention strategy.

Primary Cilia Regulates The Directional Migration And Barrier Integrity Of Endothelial Cells Through The Modulation Of Hsp27 Dependent Actin Cytoskeletal Organization, Thomas J. Jones, Ravi K. Adapala, Werner J. Geldenhuys, Chris Bursley, Wissam A. Aboualaiwi, Surya M. Nauli, Charles K. Thodeti

Pharmacy Faculty Articles and Research

Cilia are mechanosensing organelles that communicate extracellular signals into intracellular responses. Altered functions of primary cilia play a key role in the development of various diseases including polycystic kidney disease. Here, we show that endothelial cells from the oak ridge polycystic kidney (Tg737orpk/orpk) mouse, with impaired cilia assembly, exhibit a reduction in the actin stress fibers and focal adhesions compared to wild type. In contrast, endothelial cells from polycystin-1 deficient mice (pkd1null/null), with impaired cilia function, display robust stress fibers and focal adhesion assembly. We found that the Tg737orpk/orpk cells exhibit impaired directional migration and endothelial cell monolayer permeability compared …

Noninvasive Assessment And Modeling Of Diabetic Cardiovascular Autonomic Neuropathy, Siqi Wang

Theses and Dissertations--Biomedical Engineering

Noninvasive assessment of diabetic cardiovascular autonomic neuropathy (AN): Cardiac and vascular dysfunctions resulting from AN are complications of diabetes, often undiagnosed. Our objectives were to: 1) determine sympathetic and parasympathetic components of compromised blood pressure regulation in patients with polyneuropathy, and 2) rank noninvasive indexes for their sensitivity in diagnosing AN. Continuous 12-lead electrocardiography (ECG), blood pressure (BP), respiration, regional blood flow and bio-impedance were recorded from 12 able-bodied subjects (AB), 7 diabetics without (D0), 7 with possible (D1) and 8 with definite polyneuropathy (D2), during 10 minutes supine control, 30 minutes 70-degree head-up tilt and 5 minutes supine recovery. …

After Avandia: The Use Of Antidiabetic Drugs In Patients With Heart Failure, Khaled I Khalaf, Heinrich Taegtmeyer

The Texas Heart Institute Journal

Managing diabetes mellitus is an ongoing concern, especially in the presence of heart failure. Recent reports have drawn attention to adverse cardiovascular events associated with the use of thiazolidinediones, including rosiglitazone (Avandia). In 2011, the U.S. Food and Drug Administration implemented a stringent “restricted access program” for the prescription of Avandia. Other studies, which have revealed increased mortality rates in association with tight glycemic control, raise serious concerns about managing diabetes in heart-failure patients.

Herein, we provide a perspective on the management of noninsulin-dependent diabetes in patients with heart failure. We point out that thiazolidinediones exert their major effects through …

Correlates Of Morbidity And Mortality In Severe Necrotizing Pancreatitis, K. M. Pal, Pashtoon Murtaza Kasi, Mohammad Tayyeb, S. M. Faisal Mosharraf, Zafar Fatmi

Community Health Sciences

Acute severe pancreatitis is associated with a high morbidity and mortality and frequently is accompanied by underlying pancreatic parenchymal necrosis. Patients with pancreatic necrosis must be identified, because the morbidity and mortality rate in this subgroup is much higher. Our objective was to compare the clinical outcomes of these patients based on the degree of pancreatic necrosis. A total of 35 patients were noted to have pancreatic necrosis. These were divided into 2 groups based on extent of necrosis: group A had less than 50% necrosis and group B had more than 50% necrosis. The rate of mortality (5% versus …
