Diabetes is a complex metabolic disease that exposes patients to the deleterious effects of hyperglycemia on various organs. Achievement of normoglycemia with exogenous insulin treatment requires the use of high doses of hormone, which increases the risk of life-threatening hypoglycemic episodes. We developed a gene therapy approach to control diabetic hyperglycemia based on co-expression of the insulin and glucokinase genes in skeletal muscle. Previous studies proved the feasibility of gene delivery to large diabetic animals with adeno-associated viral (AAV) vectors...

Sweeteners have replaced the natural sugars in the food and beverage industry because of many reasons such as hyperglycemia and cost. Saccharin, Sucralose, Aspartame and Acesulfame-K are the most commonly used sweeteners. In the present study, the above mentioned artificial sweeteners were used to assess their glycating properties by established methods like browning, fructosamine assay, determination of carbonyl content, protein aggregation and measurement of fluorescence. Amadori and Advanced Glycation End products (AGEs) are formed as a result of the interaction between carbonyl groups of reducing sugars and amino groups of proteins and other macromolecules during Glycation...

Glycemic excursions, independent of average glucose, have been implicated in the development of diabetic implications. It is unknown if low 1,5-anyhydroglucitol (1,5-AG) are associated with advanced stages of kidney disease independent of kidney function and glycemia. In the Atherosclerosis Risk in Communities Study (N = 13,277), we used structural equation modeling to estimate the association between serum 1,5-AG levels and end-stage renal disease from baseline (1990-1992) through 2013 with adjustment for demographics, risk factors, a latent variable for glycemia (diabetes status, fasting glucose, hemoglobin A1c, fructosamine, glycated albumin), and a latent variable for kidney function (creatinine, cystatin C, β2-microglobulin)...

Type 2 diabetes mellitus (T2DM) is strongly associated with obesity. The adipose tissue secretes bioactive adipokines leading to low grade inflammation, amplified by oxidative stress, which promotes the formation of advanced glycation end products and eventually leads to dyslipidemia and vascular complications. The aim of this study was to correlate anthropometric, biochemical and oxidative stress parameters in newly diagnosed (ND) T2DM patients and to investigate the role of oxidative stress in T2DM associated with obesity...

Chronic kidney disease is associated with homeostatic imbalances such as insulin resistance. However, the underlying mechanisms leading to these imbalances and whether they promote the development of type 2 diabetes is unknown. The effect of chronic kidney disease on insulin resistance was studied on two different rat strains. First, in a 5/6th nephrectomised Sprague-Dawley rat model of chronic kidney disease, we observed a correlation between the severity of chronic kidney disease and hyperglycemia as evaluated by serum fructosamine levels (p<0...

HbA1c is the most accepted laboratory parameter for the long term observation of glucose control. There is still much of a debate about the use of HbA1c as a metabolic indicator in diabetic patients (DM) on haemodialysis (HD) and erythropoiesis-stimulating agent (ESA) therapy because of the altered erythrocyte turn over in patients with chronic kidney disease and haemodialysis (CKD5D). In 102 CKD5 patients with and without diabetes mellitus, we examined the dose dependent variability in HbA1c and fructosamine levels under haemodialysis and treated with epoetin α (n=48) and a new generation agent with continuous stimulation of methoxy polyethylene glycol epoetin beta (C...

1. CS-0777, a candidate compound for autoimmune diseases, becomes phosphorylated active metabolite, M1, by fructosamine 3-kinase (FN3K), FN3K-related protein (FN3K-RP); and M1 is reverted back to CS-0777 by alkaline phosphatase (ALP) in the body. We performed enzyme kinetic analysis of phosphorylation of CS-0777 by FN3K, FN3K-RP, human erythrocytes and human platelets; and dephosphorylation of M1 by various ALP isozymes and human liver, kidney, lung and small intestine microsomes. 2. The Michaelis constants of human FN3K, FN3K-RP and erythrocytes for CS-0777 phosphorylation were in the range from 498 μM to 1060 μM...
