The prevalence of diabetes mellitus is steadily growing throughout the world. Traditional medicine has an excellent potential in the treatment of diabetes mellitus. The present study was undertaken to evaluate the potential antidiabetic effect of peppermint essential oil (PEO) on streptozotocin (STZ) and nicotinamide induced diabetic rats. Diabetes was induced in rats fasting overnight by the intraperitoneal administration of nicotinamide followed by a single dose of STZ. After 72h, two groups of diabetic rats were treated with different doses of PEO (40 and 80mg/kg BW) respectively and one group was treated with the standard hypoglycemic agent glibenclamide...

OBJECTIVE: Accumulation of epicardial adipose tissue (EAT) is considered to be a cardiovascular risk factor independent from visceral adiposity, obesity, hypertension and diabetes. We explored the parameters related to EAT accumulation, aiming to clarify the novel pathophysiological roles of EAT in subjects with type 2 diabetes (T2DM). METHODS: We examined the laboratory values, including cystatinC, and surrogate markers used for evaluating atherosclerosis. EAT was measured as the sum of the adipose tissue area, obtained by plain computed tomography scans in 208 subjects with T2DM but no history of coronary artery disease...

Immune checkpoint inhibitors have improved survival rate in patients with advanced melanoma, but also have the potential to induce several adverse events. We report on a 63-year-old woman who had advanced melanoma and was admitted with diabetic ketoacidosis, which had occurred upon treatment with ipilimumab. On admission, the C-peptide level was low, and the HbA1c concentration was 50 mmol/l indicating a rapid onset of the disease. The patient had also been diagnosed with thyroiditis. Diabetes mellitus is a rare and serious side effect of treatment with ipilimumab, and we recommend being aware of this due to the rapid course...

AIMS/HYPOTHESIS: Roux-en-Y gastric bypass (RYGB) surgery is characterised by glycaemic variability. Prospective studies of glucose metabolism in pregnancy after RYGB are not available, therefore this study aimed to evaluate physiological alterations in glucose metabolism in pregnancy following RYGB. METHODS: Sixty-three pregnant women (25 who underwent RYGB, 19 non-operated obese control women and 19 normal weight control women) were included. Frequently sampled 3 h OGTTs and 1 h IVGTTs were performed between 24 and 28 weeks of gestation and, in a subgroup, were repeated at 3-6 months after delivery...

Identifying molecular mechanisms that regulate insulin expression in bone marrow-derived mesenchymal stem cells (bmMSCs) can provide clues on how to stimulate the differentiation of bmMSCs into insulin-producing cells (IPCs), which can be used as a therapeutic approach against type 1 diabetes (T1D). As repression factors may inhibit differentiation, the efficiency of this process is insufficient for cell transplantation. In this study, we used the mouse insulin 2 (Ins2) promoter sequence and performed a DNA affinity precipitation assay combined with liquid chromatography-mass spectrometry to identify the transcription factor, chicken ovalbumin upstream promoter transcriptional factor I (COUP-TFI)...

A purified Glycosaminoglycans (GAGs) extract from L. tessellatus eggs was enzyme-hydrolyzed and then fractionated with DEAE-Sepharose column chromatography. The fractions were subsequently subjected to skin regeneration effects analysis against skin fibroblast (CCD-986sk) cell lines. Fraction 3 is evidently to have tyrosinase inhibition activity by 20.1% at concentration of 50mg/mL. DOPA oxidation assay, collagenase inhibition activity assay, fibroblast proliferation assay, and production of type I C-peptide assays were done to further proof the skin regeneration effect of GAGs fractions...

Ghrelin secretion has been associated with increased caloric intake and adiposity. The expressions of ghrelin and its receptor (GHS-R1a) in pancreas have raised the interest about the role of ghrelin in glucose homeostasis. Most of the studies showed that ghrelin promoted hyperglycaemia and inhibited insulin secretion. This raised the interest in using GHS-R1a antagonists as therapeutic targets for type 2 diabetes. Available data of GHS-R antagonists are on a short-term basis. Moreover, the complexity of GHS-R1a signalling makes it difficult to understand the mechanism of action of GHS-R1a antagonists...

Postprandial glycemic responses to meals are inhibited by polyphenol-rich plant foods. Combinations of polyphenols may be particularly effective through complementary mechanisms. A randomized, controlled, double-blinded cross-over trial was conducted in healthy volunteers to test the hypothesis that apple and blackcurrant polyphenol-rich drinks would reduce postprandial blood glucose concentrations. Secondary outcomes included insulin and glucose-dependent insulinotropic polypeptide (GIP) secretion. Twenty men (mean age 26 y, SD 8) and 5 postmenopausal women (mean age 57 y, SD 3) consumed a placebo drink (CON) and 2 polyphenol-rich drinks containing fruit extracts: either 1200 mg apple polyphenols (AE), or 600 mg apple polyphenols+600 mg blackcurrant anthocyanins (AE+BE), in random order with a starch and sucrose meal...

Previous studies have shown that glucose fluctuation is closely related to oxidative stress and diabetic complications. However, only few studies have evaluated the influencing factors of glycemic variability (GV) in type 2 diabetes (T2D) patients so far.This was a cross-sectional study design. A total of 366 cases of hospitalized patients with T2D using insulin therapy, whom received continuous glucose monitoring from January 2014 to December 2016, were enrolled for this study. The evaluation variables of GV included standard deviation of blood glucose, coefficient of variation (CV%), mean amplitude of glycemic excursion, and absolute means of daily differences...

The canonical notion that type 1 diabetes (T1D) results following a complete destruction of β cells has recently been questioned as small amounts of C-peptide are detectable in patients with long-standing disease. We analyzed protein and gene expression levels for proinsulin, insulin, C-peptide, and islet amyloid polypeptide within pancreatic tissues from T1D, autoantibody positive (Ab+), and control organs. Insulin and C-peptide levels were low to undetectable in extracts from the T1D cohort; however, proinsulin and INS mRNA were detected in the majority of T1D pancreata...
