Abstract:

The ability of oxygen to be delivered to and utilised by cells is of fundamental importance to their ability to survive and function within normal parameters. Regulatory mechanisms within the cell provide a range of tools to facilitate the acquisition and utilisation of oxygen in such a way that the ability of the cell to function within normal parameters is not compromised. The regulation of blood flow, changes in pressure and high, and/or fluctuating concentrations of glucose will affect the ability of cells to metabolise glucose and will be of particular significance if the cell has high energy demands. Endothelial cells form the lining of the vasculature and are influenced by conditions within the diabetic milieu resulting in impaired function leading to the vascular dysfunction. Using isolated endothelial cells and a retinal vascular explant model, results will be presented to demonstrate the key role that oxygen plays in the ability of endothelial cells vessels to proliferate in a wound model. The increase in migration and proliferation resulting from decreased oxygen tension will be contrasted with the detrimental effect that high glucose concentration has on the response. In addition data demonstrating the role of anti-oxidants in the amelioration of glucose-mediated damage will be presented and the role of hyperoxia for the treatment of recalcitrant ulcers will be discussed to highlight the significance of oxygen to the onset, progression and treatment of the vascular complications of diabetes.

Haobo Li has completed his Ph.D. from Department of Anaesthesiology, The University of Hong Kong, Hong Kong SAR China, and he is now a research scientist in the same department and honorary assistant professor in Department of Anesthesiology, Affiliated Hospital of Guangdong Medical College, Zhanjiang, China. His major focus of research is the mechanism of myocardial ischemia reperfusion injury and ischemic postconditioning cardioprotection against myocardial ischemia reperfusion injury, particularly, of diabetic hearts. He has published more than 20 peer-reviewed papers and services as a reviewer for more than 4 reputed journals and grant.

Abstract:

Ischemic postconditioning (IPo) protects against myocardial ischemia reperfusion injury (MIRI) by activating signal transducer and activator of transcription 3 (STAT3) in non-diabetes, but lost its effectiveness in diabetes in which cardiac STAT3 activation is reduced concomitant with malfunction of adiponectin. Here, we found that IPo increased post-ischemic cardiomyocyte-derived adiponectin and enhanced mitochondrial STAT3 (mitoSTAT3) activation, and improved myocardial mitochondrial biogenesis and reduced oxidative stress, and eventually attenuated MIRI and improved cardiac functional recovery, in wild-type (WT) but not in adiponectin knockout (Adipo-/-) mice. Recombinant globular adiponectin (gAd) reversed the reduction of hypoxic postconditioning (HPo)-induced cardioprotective effects in cardiomyocytes isolated from Adipo-/- mice, but all these effects of adiponectin supplementation were abolished respectively by either specific STAT3 or adiponectin receptor 1(AdipoR1) gene knockdown, or caveolin-3 disruption. Adiponectin overexpression restored IPo cardioprotection by activating STAT3 in 4-week type-1 diabetic where AdipoR1 and Cav3 were functionally interactive, but not in 8-week diabetic rats whose cardiac caveolin-3 was severely reduced and AdipoR1/ caveolin-3 signaling impaired. Together, our data indicated that, under non-diabetic condition, IPo, by increasing cardiac adiponectin, activates mitoSTAT3 through AdipoR1/caveolin-3 to confer cardioprotection, while under diabetic condition, reduced adiponectin and impaired AdipoR1 and caveolin-3 interaction leads to the loss of IPo cardioprotection.

Abstract:

Mitochondrial dysfunction and reactive oxygen species (ROS) have been implicated in the diabetes process, however the underlying mechanisms are still unclear. Our previous results has shown ROS-mediated glucose metabolic reprogram induces insulin resistance in type 2 diabetes. In this study, we using MitoPBN, a mitochondrial targeted free radical scavenger, study the role of mitochondrial-derived ROS in the occurrence of diabetes. By using STZ-induced type 2 diabetic mice, we found that the diabetic mice showed an increased oxidative stress level in parallel with the raised blood glucose and impaired glucose tolerance. Meanwhile, the mitochondria-related protein, such as SIRT3, mitochondria fusion protein MFN-1 and 2, was dysregulated, thus contributing to the impaired respiratory ability and declined adenylate energy charge. In concordance with the mitochondria dysfunction, the glucose metabolism was disordered. MitoPBN treatment reduced NADH:NAD+ ratio, activated the SIRT, PCG-1α and phospho-AMPK, enhanced respiratory ability and increased adenylate energy charge so that alleviated ROS induced-mitochondria dysfunction. MitoPBN also increased glycolysis while decreased gluoconeogenisis, reversing the ROS induced-metabolic reprogram in diabetic mice. Our study suggests mitochondria-derived ROS play an important role in occurrence of diabetes. MitoPBN could be a potential drug to treat diabetes by improving mitochondrial bioenegetis ability and preventing ROS induced metabolic disorder

Abstract:

Epidemiological studies and meta-analyses report a strong relationship between chronic pain and abnormalities in glucose metabolism, but the exact relationship between chronic pain and insulin resistance in type-2-diabetes (T2D) remains unclear. Using a model of neuropathic thermal and tactile hypersensitivity induced by chronic constriction sciatic nerve injury (CCI) in Zucker diabetic fatty (ZDF) and Zucker lean (ZL) littermates, we compared the recovery period of hypersensitivity and the progression of T2D and studied the possible involvement of insulin receptors (IR) in the comorbidity of these two conditions. We found that besides a lower nociceptive thresholds to thermal and mechanical stimulation in naïve ZDF than in ZL littermates at 6 weeks of age, it took a longer time for CCI-induced nociceptive sensitivity to restore in ZDF rats. Meanwhile, nerve injury accelerated the progression of T2D in ZDF rats, demonstrated by an earlier onset of hyperglycemia, more severe hyperinsulinemia, and a higher concentration of glycosylated hemoglobin (HbAlc) 6 weeks after CCI. IR-immunoreactive cells were located across the central nervous system (CNS) and skeletal muscles. There was a low level of IR expression in skeletal muscles of naïve ZDF rats. In contrast, CCI reduced the IR expression in skeletal muscles as well as the ipsilateral spinal cord, primarily in the dorsal horn. In conclusion, our data suggest that the relationship between insulin resistance and chronic pain in ZDF rats is bidirectional and an impaired IR signaling system may be implicated in this reciprocal relationship.

Abstract:

Diabetes was declared a global burden by the International Diabetes Federation, with 382 million cases worldwide in 2013. Diabetic foot ulcers require extensive treatment and impacts heavily on patients quality of life. The ulcer recurrence rate over five years is as high as 70% and often necessitate amputation. The use of lasers and light (photobiomodulation) in medicine has made great strides and today photomedicine is practiced in a wide variety of fields, including the treatment of diabetic foot ulcers. Advances in the area of photobiomodulation continues to revolutionize and transform our world and the medical industry. The use of photobiomodulation at 660 nm with 5 J/cm2 on gene profile of 84 genes was investigated by real-time reverse transcription (RT) quantitative polymerase chain reaction (qPCR) in diabetic wounded skin fibroblast cells (WS1). The expression of various cell adhesion molecules and extracellular matrix proteins was modulated by photobiomodulation; eighteen genes were upregulated, while 31 genes were downregulated. There is a definite need to generate new treatment modalities to improve diabetic wound healing, and photobiomodulation has an unmistakable place in this. It would be ignorant to emasculate a multidisciplinary approach, and photobiomodulation needs to be adequately and critically studied alongside existing treatments in a clinical environment for its benefits to be properly recognized.

Abstract:

Insulin resistance in type 2 diabetes is a long-established fact and a target for therapeutic intervention. We present the case for there being similar resistance to testosterone causing a relative deficiency in the majority of cases of clinical onset of symptoms of deficiency of this hormone in the adult or comorbid conditions, especially metabolic syndrome. There are many parallels between resistance to the two hormones. This is seen in aetiology, age of onset, genetics, ethnicity, heredity, familial influences, association with obesity, links with viral diseases, and autoimmune conditions. Like diabetes, androgen deficiency can arise before birth, in early life, resulting in early onset, or later on leading to adult onset, with resistance playing a greater role. Similarly treatments such as weight loss and exercise have the effect of reducing resistance to both hormones. Clinical observations suggest that the duration of action of a standard dose of either pellet implants of testosterone, or an injection of testosterone undecanoate, might be a suitable measure of resistance to this hormone. Because of similar causation and co-existence of resistance to these two hormones in metabolic syndrome it is suggested that this may be new facet of the condition which because of its association with the male chromosome could be re-named as Syndrome-Y

Abstract:

Diabetes is an important metabolic disease affecting many people worldwide. Current medical problems are the management of long-term complications as well as the management of coexistence of other chronical diseases such as depression, etc. Some of this coexistent diseases may occur as a complication diabetes. Conventional therapies may not be sufficient in the management of such complicated clinical cases of diabetes. On the other hand, some of drugs used for the management of psychiatric drugs may impair glucose metabolism creating diabetic predisposition in patients. So, some alternative and complementary approaches seem to be required. Most of diabetic complications can be observed in experimental models of diabetes. Experimental models of diabetes may be employed not only for the investigation of diabetes and diabetic complications, but also for the study of drug effects on glucose metabolism and diabetic complications. These experimental techniques also allow to investigate alternative and complementary approaches. Therefore, this presentation will focus on experimental models of diabetes in relation to diabetic complications and alternative/complementary approaches discussing data from our laboratories.

Abstract:

Obesity is a complex disorder which also predisposes subjects to other diseases including type 2 diabetes. Inflammation is the common key feature in both diseases. Evidence exists that the inflammation could be induced by hypoxia or vice versa. A hypoxic and inflammatory phenotype has been reported in adipose tissue during obesity. The cellular response to hypoxia is principally regulated by hypoxia-inducible factors (HIFs). Therefore, the present part focuses HIFs-mediated effects of hypoxia in adipocyte inflammation and macrophage polarization associated with obesity pathogenesis.

Abstract:

Diabetes is associated with increased risk for atherosclerosis. Atherosclerosis is a chronic inflammatory disease. The increased inflammation and accelerated atherosclerosis are observed in diabetic patients. The inflammatory response in the pathogenesis of atherosclerosis is generated by interactions between plasma lipoproteins, monocytes/macrophages, T lymphocytes, endothelial cells, and smooth muscle cells as well as the extracellular matrix of the arteries. Macrophages are the most important cells in pathogenesis of atherosclerosis, and play main roles in generation of foam cells which produce inflammatory mediators. M1 and M2 macrophages present in the atherosclerotic plaques. M1 macrophages play an important roles in the development of plaque, on the other hand M2 macrophages help to regression of inflammation. Hyperglycemia and advanced glycation end products (AGEs) effect macrophages polarization.

Abstract:

Heart failure and arrhythmias occur more frequently in patients with type 2 diabetes (T2DM) than in the general population. T2DM is preceded by a prediabetic condition, characterized by impaired glucose tolerance or impaired fasting glucose, marked by elevated reactive oxygen species (ROS) and subclinical cardiovascular defects. Moreover, multifunctional Ca2+ calmodulin-dependent protein kinase II (CaMKII) is ROS-activated and CaMKII hyperactivity promotes heart disorders. However, a link between prediabetes and CaMKII in the heart is unprecedented. The aim of the present study was to prove the hypothesis that increased ROS and

contribute to the initial events in the development of heart failure and arrhythmogenic mechanisms, life-threatening in the overt T2DM

Abstract:

Diabetes mellitus and periodontitis are two chronic and common diseases with close relationship together affecting public health and quality of life. The aim of this study was to investigate the effect of resveratrol supplementation on blood glucose, triglyceride, periodontal status and inflammatory markers in type 2 diabetic patients with periodontal disease. This double-blind clinical trial study was conducted on 43 diabetic patients with periodontitis referred to the Endocrinology Clinic in Ahvaz, Iran. All subjects were randomly assigned into two groups of intervention and control and received either 480 mg/d resveratrol or placebo capsules (2 PCs) for four weeks. All subjects underwent non-surgical periodontal therapy during the intervention period. Anthropometric parameters, 24-hour dietary recall, fasting blood sugar, insulin, insulin resistance (HOMA-IR), triglycerides, pocket depth (PD), IL6 and TNFα were evaluated in all subjects pre- and post-intervention.The mean serum levels of fasting insulin and insulin resistance (HOMA-IR) were significantly (P=0.02, P=0.045, respectively) lower in intervention group compared with control group (10.42 ± 0.28 and 10.92 ± 0.9; 3.66 ± 0.97 and 4.49 ± 1.56, respectively). Moreover, significant difference (P < 0.001) was obtained in the mean pocket depth (PD) between intervention and control groups (2.35 ± 0.6 and 3.38 ± 0.5, respectively) post-intervention. In intervention group, the mean serum level of IL6 was reduced significantly (P= 0.039) post-intervention (1.58 ± 1.06 and 2.19± 1.09). No significant differences were seen in the mean levels of fasting blood sugar, triglycerides, IL6 and TNFα between two groups post-intervention. It is suggested that resveratrol may be recommended as adjuvant therapy along with non-surgical periodontal treatment in diabetic patients with periodontal disease

Abstract:

Normal and easy to find food item for diabetics should be available and accesible. Tofu has important role in providing perfect food for the diet of diabetics but in general made of yellow soybean. Black soybean is widely used to produce soysauce in Asian countries. Its use for tofu is still limited inspite of its excellent nutrient, prebiotic and bioactive compound but trace digestible carbohydrate content. In this research, black soybean tofu productions were optimized in the university production laboratory. The tofu product has purple color and were given in form of general simple soup containing 85 grams tofu to 15 diabetic subjects. There were 11 diabetic subjects participating in control group. The participating subjects were patients of a local neighbourhood clinic and all signed the informed consents. The tofu soup were disributed for 30 days daily while observing the subjects acceptance and general condition. Blood collections were done before and after intervention by certified nurses for analysis in the department laboratory. Consumption of black soy tofu resulted in declining of fasting glucose level (P=0.23), reduced HbA1c level and increase in plasma antioxidant status (P=0.19). SGOT / SGPT tests showed a decrement (p < 0.05), from 14.27 ± 3.81 / 21.07 ± 6.73 (U/L) to 12.73 ± 2.34 / 18.60 ± 4.29 (U/L). There were no changes in blood DNA-adduct level. We concluded that consumption of black soybean tofu contribute to improvement in overall health of diabetic subjects and may serve as important preventive food.

Abstract:

The onset of type 1 diabetes before menarche was a risk factor for the subsequent development of hyperandrogenic disorders. It has been also suggested that the use of exogenous insulin to treat type 1 diabetes mellitus in those patients may contribute to the development of PCOS. Abnormal lipid levels were also reported in children with type 1 diabetes mellitus during pubertal years. Aim of Work: This study was designed to investigate metabolic and some hormonal changes in relation to puberty among type 1 diabetic girls. Subjects and Methods: The study was carried out on 60 girls, 40 of them were type 1 diabetic patients (the diabetic group), subdivided into 2 groups (according to age and Tanner breast staging) ,and 20 of them were normal healthy girls (the control group), also subdivided into 2 groups ( according to age and Tanner breast staging). All girls were subjected to full history taking, thorough clinical examination, estimation of fasting blood glucose and HbA1c (as an estimation for glycemic control), lipid profile, hormonal profile (FSH, LH and free testosterone) in addition to pelvic ultrasound
