Irisin (Ir) deficiency may be a contributing factor in metabolic disease. This study aimed to investigate the effect of supraphysiological doses of recombinant human growth hormone (rhGH) on Ir plasma concentration in relation to metabolic disorders, including obesity and other components of metabolic syndrome. We studied 36 girls with Turner syndrome (mean age 8.2 years) treated with rhGH (0.05 mg/kg/day). Anthropometric data and fasting blood levels [e. g., Ir, insulin, glucose, glycated hemoglobin (HbA1c), IGF-1, IGFBP-3, cholesterol, insulin resistance (HOMA-IR), and β-cell function (HOMA-β)] were analyzed prior to and following rhGH therapy [mean (SD) follow-up of 1...

Purpose: Advanced glycation endproducts (AGEs) have been suggested to play a role in retinal redetachment by promoting proliferative vitreoretinopathy (PVR). The purpose of this study was to investigate whether AGEs, in combination with other clinical characteristics, were able to identify patients at high risk for redetachment after vitrectomy for rhegmatogenous retinal detachment (RRD). Methods: In this prospective cohort study, 410 RRD patients were included...

OBJECTIVES: The ratio of glycated albumin to HbA1c (GA/HbA1c ratio) is a known indicator that reflects fluctuations in plasma glucose. In this study, the association of the GA/HbA1c ratio to diabetic nephropathy and diabetic retinopathy in patients with type 2 diabetes was investigated. DESIGN AND METHODS: Among patients with type 2 diabetes, 613 patients (364 males and 249 females, aged 63.2±12.5, body mass index (BMI) 25.4±4.8kg/m(2)) were enrolled. Patients with overt proteinuria, reduced renal function, or anemia were excluded...

Accumulation of oxidized proteins is a hallmark of cellular and organismal aging. Adult muscle stem cell (or satellite cell) replication and differentiation is compromised with age contributing to sarcopenia. However, the molecular events related to satellite cell dysfunction during aging are not completely understood. In the present study we have addressed the potential impact of oxidatively modified proteins on the altered metabolism of senescent human satellite cells. By using a modified proteomics analysis we have found that proteins involved in protein quality control and glycolytic enzymes are the main targets of oxidation (carbonylation) and modification with advanced glycation/lipid peroxidation end products during the replicative senescence of satellite cells...

Vascular complications of diabetes result from long lasting unsatisfactory glycemic control. We usually assess glycemic control based on the value of glycated hemoglobin HbA1c. The glycated hemoglobin test, however, says nothing about short-term glycemic fluctuations. Recently, continuous monitoring of glycemia has enabled us an in-depth assessment of changes in glucose concentrations, called glycemic variability. In connection with the research into short-term glycemic variability, also the study of long-term fluctuations in glycemic control based on HbA1c variability has now intensified...

Obstructive sleep apnoea syndrome (OSA) is a disease very frequently occurring in people with type 2 diabetes, that significantly increases cardiovascular morbidity and mortality. In a number of studies, OSA has been identified as an independent risk factor for the development of insulin resistance, glucose intolerance and type 2 diabetes mellitus. Disorders of glucose homeostasis in patients with OSA are probably mediated by chronic intermittent hypoxia and/or sleep fragmentation through activation of the sympathetic nervous system, the hypothalamic-pituitary-adrenal stress axis, pro-inflammatory paths or oxidative stress...

Inositol hexakisphosphate (IP6) and inositol both regulate insulin secretion, but their combined use in the management of diabetes deserves investigation. The combined effects of IP6 and inositol supplementation were investigated in streptozotocin-induced type 2 diabetic rats. The following groups of rats were studied for 8 weeks: non-diabetic control, non-diabetic high-fat diet control, diabetic untreated, diabetic rats treated with the combination of IP6 and inositol (650 mg/kg bw) and diabetic rats treated with glibenclamide (10 mg/kg bw)...

Tartary buckwheat (TB) is rich in protein, dietary fiber, and flavonoids and has been reported to affect type 2 diabetes mellitus (T2DM) in animal experiments, but limited information on the benefit of TB as a whole food in T2DM patients is available. Thus, we tested the hypothesis that a daily replacement of a portion of the staple food with TB will improve risk factors of T2DM, including fasting glucose, insulin resistance, and lipid profile. In a parallel, randomized, open-label, controlled trial, 165 T2DM patients were randomly assigned to a control diet group (DC group; systematic diet plans and intensive nutritional education) or a TB intervention group (TB group; daily replacement of a portion of staple food with TB food)...

Clinical observations suggests that Type II Diabetes patients are more susceptible to skin changes which may be associated with reduced coefficient of friction at the fingertips. Reduced coefficient of friction may explain recent reports of fine motor dysfunction in diabetic patients. Coefficient of friction was evaluated using slip force evaluation in a cross-sectional cohort of diabetic patients and age- and sex-matched healthy controls. Covariates of tactile sensation, disease duration, glycated hemoglobin, and clinical diagnosis of peripheral neuropathy were also assessed...

S100P is known to affect tumor development and metastasis of various cancers, but its role in endometrial cancer is unclear. We reported that S100P expression was dramatically elevated in both endometrial squamous cell carcinoma and adenosquamous carcinoma, but not in adenocarcinoma and normal endometrial samples. Moreover, we revealed an oncogenic role of S100P promoting cell proliferation, invasion, and migration while reducing apoptosis, possibly via its upregulation and/or activation of receptors of advanced glycation end products and consequently the oncogenic PI3K-AKT and MAPK pathways...

Diabetic neuropathy may be one of the most common and severe complications of diabetes mellitus. Oxidative stress plays a pivotal role in the development of microvascular complications of diabetes. The majority of related pathways like polyol and hexosamine, advanced glycation end products, poly-ADP-ribose polymerase, and protein kinase-C all originated from initial oxidative stress. In this review, the authors present the current oxidative stress hypothesis in diabetes mellitus and summarize the pathophysiological mechanisms of diabetic neuropathy associated with increased oxidative stress...

The chemical reactivity of resveratrol isomers with the potential to play a role as inhibitors of the nonenzymatic glycation of amino acids and proteins, both acting as antioxidants and as chelating agents for metallic ions such as Cu, Al and Fe, have been studied by resorting to the latest family of Minnesota density functionals. The chemical reactivity descriptors have been calculated through Molecular Electron Density Theory encompassing Conceptual DFT. The active sites for nucleophilic and electrophilic attacks have been chosen by relating them to the Fukui function indices, the dual descriptor f ( 2 ) ( r ) and the electrophilic and nucleophilic Parr functions...

REVIEW
Alyssa Faria, Shanta J Persaud
Macrovascular complications of diabetes, including diabetic cardiovascular disease (CVD), occur through a number of hyperglycaemia-induced mechanisms that include generation of oxidative stress, accumulation of advanced glycation end-products (AGE) and activation of protein kinase C (PKC). Cardiac oxidative stress is associated with increased cardiac fibrosis and hypertrophy, and reduced cardiac performance and contractility, leading to severe cardiac dysfunction and potentially fatal cardiac events. It occurs under conditions of excessive synthesis of reactive oxygen species (ROS)...
