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 …

This study investigated the role of stromal cell-derived factor-1α (SDF-1α)/CXC chemokine receptor 4 (CXCR4) axis in brain and endothelial progenitor cells (EPCs), and explored the efficacy of CXCR4 primed EPCs in treating ischemic stroke in diabetes. The db/db diabetic and db/+ mice were used in this study. Levels of plasma SDF-1α and circulating CD34+CXCR4+ cells were measured. Brain SDF-1α and CXCR4 expression were quantified at basal and after middle cerebral artery occlusion (MCAO). In in vitro study, EPCs were transfected with adenovirus carrying null (Ad-null) or CXCR4 (Ad-CXCR4) followed with high glucose (HG) treatment for 4 days. For pathway block …

Evidence Based Adolescent Type 2 Diabetes Prevention, Susan Henley, Abby Jane Toburen, Lauren Howsden

Pharmacy and Nursing Student Research and Evidence-Based Medicine Poster Session

Type 2 Diabetes (T2DM) is a growing problem in the pediatric population. Contributing factors are poor nutrition, lack of education, and decrease in exercise. The purpose of this study is to determine the best interventions to prevent T2DM in children.

Review Of Non-Invasive And Non-Pharmacological Interventions For The Prevention Of Gestational Diabetes Mellitus, Marcia Pinkerton, Chelsea Powell

Pharmacy and Nursing Student Research and Evidence-Based Medicine Poster Session

Gestational Diabetes Mellitus (GDM) affects around 7% of pregnant women in America. Prevalence is increasing just as obesity is in the general population. Adverse effects of GDM for both mother and baby include the mother having a greater chance of needing C-section, preterm delivery, and hypoglycemia, and, for the newborn, hypoglycemia. Both have greater risk of developing Type 2 Diabetes Mellitus. The purpose of this study is to review the evidence for the most effective non-invasive and non-pharmacological interventions to reduce GDM.

Background

Cardio-metabolic diseases (CMDs) are a growing public health problem, but data on incidence, trends, and costs in developing countries is scarce. Comprehensive and standardised surveillance for non-communicable diseases was recommended at the United Nations High-level meeting in 2011.

Aims: To develop a model surveillance system for CMDs and risk factors that could be adopted for continued assessment of burdens from multiple perspectives in South-Asian countries.

Methods

Design: Hybrid model with two cross-sectional serial surveys three years apart to monitor trend, with a three-year prospective follow-up of the first cohort.

Sites: Three urban settings (Chennai and New Delhi in India; …

Mice Deficient In Gem Gtpase Show Abnormal Glucose Homeostasis Due To Defects In Beta-Cell Calcium Handling, Jenny E. Gunton, Mary Sisavanh, Rebecca A. Stokes, Jon Satin, Leslie S.

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 …

Endocrine Complications In Patients Of Beta Thalassemia Major In A Tertiary Care Hospital In Pakistan, Amina Adil, Zain A. Sobani, Abdul Jabbar, Salman N Adil, Safia Awan

Section of Diabetes, Endocrinology and Metabolism

OBJECTIVE: To determine the major endocrine complications present in patients of Thalassemia major presenting to a tertiary care center in Karachi, Pakistan.

METHODS: Records of all thallasemia major patients at a Haematology Department in a tertiary care hospital of Karachi were retrospectively reviewed from May to August 2009 with specific focus on endocrine data and investigations. The patients' data was recorded in a questionnaire and analyzed using SPSS v.17, frequencies and percentages along with corresponding 95% confidence interval were computed.

RESULTS: Our data revealed that a significantly small percentage of those under care received regular endocrine follow-up. Male hypo-gonadal abnormalities …

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 & Occupational Health Faculty Publications

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.

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 …

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 …
