PURPOSES: Abnormal islet microcirculation impetus the insulin production and accelerates progression of Type 1 and 2 diabetes. In this study, we investigated whether tetramethylpyrazine phosphate (TMPP), a vasoactive substance, could regulate the islet microcirculation and insulin concentration and improve glycaemia in SD rats. METHODS: SD rats were randomly divided into two groups, the control and TMPP groups. Each group was further divided into three subgroups according to the intravenous injection of either saline, 15 or 30% glucose...

The compound 2-deoxy-2-fluoro-α-D-glucopyranosyl fluoride (F2Glc), which is a nonmetabolized superior glucose analogue, is a potent inhibitor of glycogen phosphorylase and pharmacological properties are reported. Glycogen phosphorylase (GP) and glycogen synthase (GS) are responsible of the degradation and synthesis, respectively, of glycogen which is a polymer of glucose units that provides a readily available source of energy in mammals. GP and GS are two key enzymes that modulate cellular glucose and glycogen levels; therefore, these proteins are suggested as potential targets for the treatment of diseases related to glycogen metabolism disorders...

REVIEW
Gauri Dhir, Kenneth Cusi
Obesity is a major risk factor for the development of type 2 diabetes mellitus (T2DM), and is associated with a cluster of metabolic factors that lead to poor cardiovascular outcomes. In non-alcoholic fatty liver disease (NAFLD), liver fat (triglyceride) accumulation closely mirrors adipose tissue dysfunction and insulin resistance in obesity and T2DM. It is now recognized as the most common chronic liver disease in Westernized societies, often progressing to more severe forms of the disease such as nonalcoholic steatohepatitis (NASH), or cirrhosis and hepatocellular carcinoma...

BACKGROUND AND OBJECTIVES: The American Society for Parenteral and Enteral Nutrition recommends hypocaloric feeding for critically ill patients with a BMI of >=30.0 kg/m2. However, the cut-off value of obesity in Japan is BMI >25.0 kg/m2, due to the higher prevalence of type 2 diabetes mellitus, and cardiovascular risk factors, even at a lower BMI than in Western populations. Thus, the optimal energy intake for critically ill, overweight Asian patients is unknown. METHODS AND STUDY DESIGN: A retrospective chart review was conducted in patients with BMI of >=25...

Human islet amyloid polypeptide (hIAPP) is a natively unfolded polypeptide hormone of glucose metabolism, which is co-secreted with insulin by the β-cells of the pancreas. In patients with type 2 diabetes, IAPP forms amyloid fibrils because of diabetes-associated β-cells dysfunction and increasing fibrillation, in turn, lead to failure of secretory function of β-cells. This provides a target for the discovery of small organic molecules against protein aggregation diseases. However, the binding mechanism of these molecules with monomers, oligomers and fibrils to inhibit fibrillation is still an open question...

Selenium is an essential element incorporated to different proteins with important biological functions in connection to antioxidant activity, cancer-protective properties, neurodegenerative pathologies, and prevention of effects of diabetes, among others. In addition, selenoamino acids play a basic role in the global equilibrium of key selenium-biomolecules synthesis, including selenoprotein P, selenoalbumin, and glutathione peroxidase. Homeostasis of these selenium-containing biomolecules involves different organs in living organisms including human, and bloodstream is the connection fluid in this process...

The 2013 American Heart Association Blood Cholesterol Guidelines increased the number of patients recommended for statin therapy in the United States to 56million. Two common statin side effects are muscle pain, referred to as "statin-associated muscle symptoms", and increased risk for new onset type-2-diabetes mellitus. Up to 25% of statin users report muscle symptoms resulting in many patients being switched to lower dose or lower potency statins, or refusing statins altogether. The most likely signaling mechanisms for statin-associated muscle symptoms overlaps with the proposed mechanism of statin-induced insulin resistance...

BACKGROUND: Good glycaemic control in type 2 diabetes (T2DM) protects the microcirculation. Current guidelines suggest glycaemic targets be relaxed in advanced diabetes. We explored whether disease duration or pre-existing macrovascular complications attenuated the association between hyperglycaemia and microvascular function. METHODS: 743 participants with T2DM (n = 222), cardiovascular disease (CVD = 183), both (n = 177) or neither (controls = 161) from two centres in the UK, underwent standard clinical measures and endothelial dependent (ACh) and independent (SNP) microvascular function assessment using laser Doppler imaging...

BACKGROUND: Body mass index (BMI) cut-off values (>25 and >30) that predict diabetes risk have been well validated in Caucasian populations but less so in Asian populations. We aimed to determine the BMI threshold associated with increased type 2 diabetes (T2DM) risk and to calculate the proportion of T2DM cases attributable to overweight and obesity in the Thai population. METHODS: Participants were those from the Thai Cohort Study who were diabetes-free in 2005 and were followed-up in 2009 and 2013 (n = 39,021)...

Type 2 diabetes (T2DM) is a complex disease linked to pancreatic beta-cell failure and insulin resistance. Current antidiabetic treatment regimens for T2DM include insulin sensitizers and insulin secretagogues. We have previously demonstrated that leptolide, a member of the furanocembranolides family, promotes pancreatic beta-cell proliferation in mice. Considering the beneficial effects of leptolide in diabetic mice, in this study, we aimed to address the capability of leptolide to improve insulin resistance associated with the pathology of obesity...

In the Trial Comparing Cardiovascular Safety of Insulin Degludec vs Insulin Glargine in Patients with Type 2 Diabetes at High Risk of Cardiovascular Events (DEVOTE), insulin degludec was non-inferior to insulin glargine in terms of cardiovascular events and mortality. However, there were lower rates of severe hypoglycaemia with insulin degludec. DEVOTE investigators now extend these findings by presenting the results of two observational epidemiological analyses based on trial data. In the first of these analyses (DEVOTE 2), Zinman et al (Diabetologia DOI: 10...

Alcoholic steatohepatitis (ASH) and nonalcoholic steatohepatitis (NASH) are representative types of fatty liver disease (FLD) and have similar histologic features. In this study, we aimed to compare the associations of the two FLD types with hypertension (HT), diabetes mellitus (DM), and dyslipidemia (DL). A nationwide survey investigating FLD status included 753 Japanese subjects (median age 55 years; male 440, female 313) with biopsy-proven ASH (n = 172) or NASH (n = 581). We performed a multiple logistic regression analysis to identify the factors associated with HT, DM, or DL...

OBJECTIVE: Obesity is associated with an increased risk of type 2 diabetes and cardiovascular complications. The risk depends significantly on adipose tissue distribution. Liraglutide, a glucagon-like peptide 1 analog, is associated with weight loss, improved glycemic control, and reduced cardiovascular risk. We determined whether an equal degree of weight loss by liraglutide or lifestyle changes has a different impact on subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) in obese subjects with prediabetes or early type 2 diabetes...

AIMS/HYPOTHESIS: Better understanding of type 2 diabetes and its prevention is a pressing need. Changes in human plasma N-glycome are associated with many diseases and represent promising diagnostic and prognostic biomarkers. Variations in glucose metabolism directly affect glycosylation through the hexosamine pathway but studies of plasma glycome in type 2 diabetes are scarce. The aim of this study was to determine whether plasma protein N-glycome is changed in individuals who are at greater risk of developing type 2 diabetes...
