Clinical studies have shown that patients with early Type 2 diabetes often have elevated serum glucagon rather than insulin deficiency. Imbalance of insulin and glucagon in favouring the latter may contribute to impaired glucose tolerance, persistent hyperglycaemia, microalbuminuria and glomerular injury. In the present study, we tested the hypothesis that long-term glucagon infusion induces early metabolic and renal phenotypes of Type 2 diabetes in mice by activating glucagon receptors. Five groups of adult male C57BL/6J mice were treated with vehicle, glucagon alone (1 μg/h via an osmotic minipump, intraperitoneally), glucagon plus the glucagon receptor antagonist [Des-His1-Glu9]glucagon (5 μg/h via an osmotic minipump), [Des-His1-Glu9]glucagon alone or a high glucose load alone (2% glucose in the drinking water) for 4 weeks. Glucagon infusion increased serum glucagon by 129% (P<0.05), raised systolic BP (blood pressure) by 21 mmHg (P<0.01), elevated fasting blood glucose by 42% (P<0.01), impaired glucose tolerance (P<0.01), increased the kidney weight/body weight ratio (P<0.05) and 24 h urinary albumin excretion by 108% (P<0.01) and induced glomerular mesangial expansion and extracellular matrix deposition. These responses were associated with marked increases in phosphorylated ERK1/2 (extracellular-signal-regulated kinase 1/2) and Akt signalling proteins in the liver and kidney (P<0.01). Serum insulin did not increase proportionally. Concurrent administration of [Des-His1-Glu9]glucagon with glucagon significantly attenuated glucagon-increased BP, fasting blood glucose, kidney weight/body weight ratio and 24 h urinary albumin excretion. [Des-His1-Glu9]glucagon also improved glucagon-inpaired glucose tolerance, increased serum insulin by 56% (P<0.05) and attenuated glomerular injury. However, [Des-His1-Glu9]glucagon or high glucose administration alone did not elevate fasting blood glucose levels, impair glucose tolerance or induce renal injury. These results demonstrate for the first time that long-term hyperglucagonaemia in mice induces early metabolic and renal phenotypes of Type 2 diabetes by activating glucagon receptors. This supports the idea that glucagon receptor blockade may be beneficial in treating insulin resistance and Type 2 diabetic renal complications.

Abstract Background: This research aimed to study the effect of coriander seed supplementation on serum glycemic indices, lipid profile and oxidative stress parameters in patients with type 2 diabetes mellitus (T2DM).Methods: In this randomized double-blinded, placebo-controlled trial, eligible 40 T2DM patients aged 30-60 years were recruited from Sina Hospital (Tabriz, Iran) and randomly assigned into two groups to receive either coriander seed powder (1000 mg/day, n=20) or placebo (1000 mg/day, n=20) for 6 weeks. Anthropometric measurements, dietary intake, and biochemical parameters including fasting blood sugar (FBS), serum insulin, Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), total cholesterol (TC), triglyceride (TG), high- and low-density lipoprotein cholesterols (HDL-C and LDL-C), malondialdehyde (MDA), and total antioxidant capacity (TAC) were assessed before and after supplementation.Results: Anthropometric measurements were not significantly different between intervention and placebo groups. Coriander seed supplementation led to significant within-group reductions in FBS (156.15±23.19 to 130.30±21.15), serum insulin (17.72±0.47 to 17.12±0.76), HOMA-IR (6.82±0.95 to 5.52±0.99), TC (183.85±55.68 to 145.20±31.36), TG (152.50±37.59 to 130.40 ±27.96), LDL-C (127.35±23.45 to 111.40±25.71), and MDA (1.65±0.15 to 1.49±0.15), whereas there were significant increases observed in serum TAC (1.93±0.12 to 1.97±0.09) (P<0.05). Post-dose comparisons showed significant between-group differences for FBS, serum insulin, HOMA-IR, TC, TG, LDL-C, MDA, and TAC levels after adjusting for baseline values (P<0.05).Conclusions: Coriander seed supplementation was able to improve glycemic indices, lipid profile and oxidative stress status in T2DM and it may be useful complementary treatment in management of these patients.Trial registration: The study protocol was registered on the Iranian Registry of Clinical Trials website (IRCT20190224042821N2) on 2019/Oct/11.

Chronic Hyperglycemia

Type 2 diabetes mellitus (T2DM) is characterized by chronic hyperglycemia and progressive insulin resistance, leading to macro and microvascular dysfunction. Passive heating has potential to improve glucose homeostasis and act as an exercise mimetic. We assessed the effect of acute passive heating before or during an oral glucose tolerance test (OGTT) in people with T2DM. Twelve people with T2DM were randomly assigned to 3 conditions:1) 3 h OGTT (CON); 2) 1 h passive heating (40 °C water) 30 min before an OGTT (HOT-OGTT); and 3) 1 h passive heating (40 °C water) 30 min after commencing an OGTT (OGTT-HOT). Blood [glucose], insulin sensitivity, extracellular heat shock protein 70 (eHSP70), total energy expenditure (TEE), heart rate (HR), systolic (SBP) and diastolic blood pressure (DBP) were recorded. Passive heating did not alter blood [glucose] (CON, 1,677 (386) a.u.; HOT-OGTT, 1,797 (340) a.u.; OGTT-HOT, 1,662 (364) a.u.; P = 0.28), insulin sensitivity (P = 0.15), or SBP (P = 0.18), but did increase [eHSP70] in both heating conditions (CON, 203.48 (110.81) pg·mL-1; HOT-OGTT, 402.47 (79.02) pg·mL-1; OGTT-HOT, 310.00 (60.53) pg·mL-1; P < 0.001), increased TEE (via fat oxidation) in the OGTT-HOT condition (CON, 263 (33) kcal; HOT-OGTT, 278 (40) kcal; OGTT-HOT, 304 (38) kcal; P = 0.001), increased HR in both heating conditions (P < 0.001) and reduced DBP in OGTT-HOT condition (P < 0.01). Passive heating in close proximity to a glucose challenge does not alter glucose tolerance but does increase [eHSP70] and TEE, and reduce blood pressure in people with T2DM.

Background: The prevalence of diabetes is on the increase in the UK and worldwide, partly due to unhealthy lifestyles, including poor dietary regimes. Patients with diabetes and other co-morbidities such as stroke, which may affect swallowing ability and lead to malnutrition, could benefit from enteral nutrition, including the standard formula (SF) and diabetes-specific formulas (DSF). However, enteral nutrition presents its challenges due to its effect on glycaemic control and lipid profile. Aim: The aim of this review was to evaluate the effectiveness of diabetes-specific enteral nutrition formula versus SF in managing cardiometabolic parameters in patients with type 2 diabetes. Method: This review was conducted in accordance with the preferred reporting items for systematic reviews and meta-analyses. Three databases (Pubmed, EMBASE, PSYCInfo) and Google scholar were searched for relevant articles from inception to 2 January 2019 based on Population, Intervention, Comparator, Outcomes and Study designs (PICOS) framework. Key words, Medical Subject Heading (MeSH) terms, and Boolean operators (AND/OR) formed part of the search strategy. Articles were evaluated for quality and risks of bias. Results: Fourteen articles were included in the systematic review and five articles were selected for the meta-analysis. Based on the findings of the review and meta-analysis, two distinct areas were evident: the effect of DSF on blood glucose parameters and the effect of DSF on lipid profile. All fourteen studies included in the systematic review showed that DSF was effective in lowering blood glucose parameters in patients with type 2 diabetes compared with SF. The results of the meta-analysis confirmed the findings of the systematic review with respect to the fasting blood glucose, which was significantly lower (p = 0.01) in the DSF group compared to SF, with a mean difference of −1.15 (95% CI −2.07, −0.23) and glycated haemoglobin, which was significantly lower (p = 0.005) in the DSF group compared to the SF group following meta-analysis and sensitivity analysis. However, in relation to the sensitivity analysis for the fasting blood glucose, differences were not significant between the two groups when some of the studies were removed. Based on the systematic review, the outcomes of the studies selected to evaluate the effect of DSF on lipid profile were variable. Following the meta-analysis, no significant differences (p > 0.05) were found between the DSF and SF groups with respect to total cholesterol, LDL cholesterol and triglyceride. The level of the HDL cholesterol was significantly higher (p = 0.04) in the DSF group compared to the SF group after the intervention, with a mean difference of 0.09 (95% CI, 0.00, 0.18), although this was not consistent based on the sensitivity analysis. The presence of low glycaemic index (GI) carbohydrate, the lower amount of carbohydrate and the higher protein, the presence of mono-unsaturated fatty acids and the different amounts and types of fibre in the DSF compared with SF may be responsible for the observed differences in cardiometabolic parameters in both groups. Conclusion: The results provide evidence to suggest that DSF is effective in controlling fasting blood glucose and glycated haemoglobin and in increasing HDL cholesterol, but has no significant effect on other lipid parameters. However, our confidence in these findings would be increased by additional data from further studies.

Background: Type 2 diabetes (T2D) is the most common form of diabetes and accounts for 90-95% of all existing diabetic cases. The main etiologies of T2D include insulin resistance in target tissues, insufficient secretion of insulin and subsequent decline of pancreatic β-cell function. Recently, many studies have suggested that adipose – derived stem cells (ASCs) were potential to alleviate insulin resistance and hyperglycemia and promote the islets repair. In this study, ASCs were hypothesized that they could have ameliorative effects on type 2 diabetic mice.  Methods: Type 2 diabetic mice were induced by a combination of high-fat diet and injection of STZ 100 mg/kg and NA 120 mg/kg. Thereafter, two doses of 106 human ASCs were transplanted 2 week interval into each mouse via the tail vein. The mice were monitored health condition, rate of mortaity, body weight, consumption of food and water, blood glucose level, serum insulin level and histological structure of pancreatic islets.  Results: Our results indicated that the ASC-treated mice expressed improved condition in comparision with non-treated diabetic mice. The consumption of food and water as well as the blood glucose level decreased. Simultaneously, ASC transplantation improved the impaired glucose tolerance and insulin tolerance in T2D mice. Besides, the total cholesterol have significantly decreased.  Conclusion: it is suggested that human ASCs infusion is safe and effective for type 2 diabetes mellitus in mice regarding the improved glucose metabolism and insulin resistance.
