Epidemiological evidence suggests a correlation between diabetes and age-related neurodegenerative disorders, including Alzheimer's and Parkinson's diseases. Hyperglycemia causes oxidative stress in vulnerable tissues such as the brain. We recently demonstrated that elevated levels of glucose lead to the death of dopaminergic neurons in culture through oxidative mechanisms. Considering the lack of literature addressing dopaminergic alterations in diabetes with age, the goal of this study was to characterize the state of 2 critical dopaminergic pathways in the nicotinamide-streptozotocin rat model of long-term hyperglycemia, specifically the nigrostriatal motor pathway and the reward-associated mesocorticolimbic pathway...

Subcellular organelles consist of smaller substructures called supramolecular assemblies and these in turn consist of macromolecules. Various subcellular organelles have critical functions that consist of genetic disorders of organelle biogenesis and several metabolic disturbances that occur during non-genetic diseases e.g. infection, intoxication and drug treatments. Mitochondrial damage can cause renal dysfunction as ischemic acute renal injury, chronic kidney disease progression. Moreover, mitochondrial dysfunction is an early event in aldosterone-induced podocyte injury and cardiovascular disease due to oxidative stress in chronic kidney disease...

PURPOSE OF REVIEW: Glucagon is known as a key hormone in the control of glucose and amino acid metabolism. Critical illness is hallmarked by a profound alteration in glucose and amino acid metabolism, accompanied by muscle wasting and hypoaminoacidemia. Here we review novel insights in glucagon (patho)physiology and discuss the recently discovered role of glucagon in controlling amino acid metabolism during critical illness. RECENT FINDINGS: The role of glucagon in glucose metabolism is much more complex than originally anticipated, and glucagon has shown to be a key player in amino acid metabolism...

The interaction of advanced glycation end products (AGE) and their receptors promote vascular complications of diabetes in hemodialysis (HD) patients. The soluble form of the receptor for the advanced glycation end-products (sRAGE) has been studied as a vascular biomarker in various diseases with controversial results. Our aim was to evaluate the association of the serum levels of the AGEs and their receptor sRAGE with cardiovascular disease (CVD) and the cardiovascular risk factors among HD patients. There were 130 HD patients and 80 age and gender matched control subjects were involved; 31...

OBJECTIVES: There is currently no evidence that whether magnesium supplementation would improve stress-induced hyperglycemia (SIH) in critically ill patients. In this study, effects of magnesium loading dose on insulin resistance (IR) indices were evaluated in critically ill patients without diabetes having SIH. METHODS: Seventy critically ill patients with SIH were assigned to receive a loading dose of magnesium (7.5 g of magnesium sulfate in 500 mL normal saline as intravenous infusion over an 8-hour period) or placebo...

INTRODUCTION: Healthy eating is a critical aspect of the prevention and management of type 2 diabetes (T2DM). Disrupted eating patterns can result in poor glucose control and increase the likelihood of diabetic complications. Teneligliptin inhibits dipeptidyl peptidase-4 activity for 24 h and suppresses postprandial hyperglycemia after all three daily meals. This interim analysis of data from the large-scale post-marketing surveillance of teneligliptin (RUBY) in Japan examined eating patterns and their relationship with metabolic parameters and diabetic complications...

An organized series of complicated biological and molecular phenomena is required for normal skin wound healing. These processes depend on normal cellular responses to cytokines, growth factors, and other mediators, such as clotting factors, prostaglandins, free radicals, and nitric oxide. In diabetic ulcers, impaired responses to these molecules lead to abnormalities in vascularization, innervation, matrix reconstruction, and reepithelialization of wounds. keratinocyte migration and proliferation on an extracellular matrix is critical in reepithelialization, but the response to growth factors is blunted in diabetes, including the insulin/IGF-1signaling axis...

Diabetes and hyperglycemia are present in over one-third of inpatients in internal medicine units and are associated with worse prognosis in multiple morbidities. Treatment of inpatient hyperglycemia is usually with basal bolus insulin in a dose calculated by the patient's weight, with lower doses recommended in patients who are at a higher risk for hypoglycemia. Other antihyperglycemic medications and insulin regimens can be used in selected patients. There are no adequately powered studies on the effect of improving glycemic control on hospitalization outcomes in non-critically ill patients in internal medicine units, and in most patients a modest glucose target of 140-180 mg/dL is recommended...

Diabetes and cancer are worldwide chronic diseases with a major impact on the quality and expectancy of life. Metabolic abnormalities observed during the onset and progression of diabetes may have a critical role on the initiation and progression of carcinogenesis. To date, there are no conclusive data on the mechanisms underlying the relationship between diabetes and any type of human cancer. However, recent evidence suggests that both hyperglycemia and hyperinsulinemia in diabetes could elicit cell damage responses, such as glucotoxicity, lipotoxicity and oxidative stress, which participate in the cell transformation process raising the risk of cancer development...

The extant literature finds that children with type 1 diabetes mellitus (T1D) experience mild cognitive alterations compared to healthy age-matched controls. The neural basis of these cognitive differences is unclear but may relate in part to the effects of dysglycemia on the developing brain. We investigated longitudinal changes in hippocampus volume in young children with early-onset T1D. Structural magnetic resonance imaging data were acquired from 142 children with T1D and 65 age-matched control subjects (4-10 years of age at study entry) at 2 time points, 18 months apart...

NF-E2 p45-related factor 2 (Nrf2), is a major redox sensitive transcription factor that plays an essential role in regulating glucose metabolism. Inactivation of Nrf2 has been associated with diabetic complications however, mechanisms warranting Nrf2 suppression are incompletely understood. We hypothesized that PHLPP1 activates GSK3β to induce β-TrCP mediated Nrf2 phosphorylation and degradation. In vivo study was carried out in STZ-NA induced type 2 diabetic male Wistar rats. GSK3β mediated Nrf2 ubiquitination was confirmed by administration of GSK3β inhibitor (LiCl; 60 mg/kg bwt...

Mechanism underlying the diabetes-induced poor osteointegration of implants remains elusive, making it a challenge to develop corresponding solutions. Here, we studied the role of angiogenesis in the diabetes-induced poor bone repair at the bone-implant interface (BII) and the related mechanisms. In vivo, titanium screws were implanted in the femurs of mice, and, in vitro, vascular endothelial cell (VEC) was cultured on titanium surface. Results showed that, compared with normal milieu (NM), diabetic milieu (DM) led to angiogenesis inhibition around implants which resulted in reduced osteoprogenitors and poor bone formation on BII in vivo...

The prevalence of hypertension in children with type 1 diabetes is reported to be between 6% and 16%. This potentially modifiable cardiovascular risk factor may go undiagnosed and undertreated, particularly in children with type 1 diabetes. Recent updated Canadian clinical practice guidelines recommend blood pressure screening every 2 years in children with type 1 diabetes as well as routine use of ambulatory blood pressure monitoring. Risk factors for hypertension in type 1 diabetes include poor glycemic control, overweight and obesity and genetic predisposition for hypertension...
