An efficient acid-hydrolysis method was developed and optimized for the hydrolyses of polysaccharide from Auricularia auricula with the ABTS· scavenging ability as the detective marker. Based on the single factor experimental results, Box-Behnken design (BBD) were applied for the optimization of acid-hydrolysis conditions. The possible antioxidant mechanism of the hydrolyses (AAPs-F) in vivo was performed using the C. elegans model. The acid-hydrolysis conditions were found to be the optimal hydrolyzing time 2...

Interleukin-1 receptor antagonist (IL-1Ra) is elevated in the circulation during obesity and type 2 diabetes (T2D) but is decreased in islets from patients with T2D. The protective role of local IL-1Ra was investigated in pancreatic islet β cell (βIL-1Ra)-specific versus myeloid-cell (myeloIL-1Ra)-specific IL-1Ra knockout (KO) mice. Deletion of IL-1Ra in β cells, but not in myeloid cells, resulted in diminished islet IL-1Ra expression. Myeloid cells were not the main source of circulating IL-1Ra in obesity...

The antidiabetic potential of glucagon receptor antagonism presents an opportunity for use in an insulin-centric clinical environment. To investigate the metabolic effects of glucagon receptor antagonism in type 2 diabetes, we treated Leprdb/dband Lepob/obmice with REMD 2.59, a human monoclonal antibody and competitive antagonist of the glucagon receptor. As expected, REMD 2.59 suppresses hepatic glucose production and improves glycemia. Surprisingly, it also enhances insulin action in both liver and skeletal muscle, coinciding with an increase in AMP-activated protein kinase (AMPK)-mediated lipid oxidation...

AgRP neurons control peripheral substrate utilization and nutrient partitioning during conditions of energy deficit and nutrient replenishment, although the molecular mechanism is unknown. We examined whether carnitine acetyltransferase (Crat) in AgRP neurons affects peripheral nutrient partitioning. Crat deletion in AgRP neurons reduced food intake and feeding behavior and increased glycerol supply to the liver during fasting, as a gluconeogenic substrate, which was mediated by changes to sympathetic output and peripheral fatty acid metabolism in the liver...

Sugars play important roles in regulating plant growth, development and stomatal movement. Here, we found that glucose triggered stomatal closure, showing a dose-and time-dependent manner in Arabidopsis. Pharmacological data showed that glucose-induced stomatal closure was greatly inhibited by catalase (CAT, a reactive oxygen species (ROS) scavenger), diphenyleneiodonium chloride (DPI, an NADPH oxidase inhibitor), lanthanum chloride (LaCl3, a Ca2+ channel blocker), ethylene glycol tetraacetic acid (EGTA, a Ca2+ chelator), two nitrate reductase (NR) inhibitors, tungstate and sodium azide (NaN3), while not affected by salicylhydroxamic acid (SHAM, a peroxidase inhibitor)...

A computational model of the physiological mechanisms driving an individual's health towards onset of type 2 diabetes (T2D) is described, calibrated and validated using data from the Diabetes Prevention Program (DPP). The objective of this model is to quantify the factors that can be used for prevention of T2D. The model is energy and mass balanced and continuously simulates trajectories of variables including body weight components, fasting plasma glucose, insulin, and glycosylated hemoglobin among others on the time-scale of years...

Minimally processed cereal breakfast products from whole grain entered the market due to consumer demand of more nutritional food with more controlled sugar release. However, the subsequent processing of such products with different cooking methods in the consumer's kitchen may lead to significant differentiation of their nutritional value. Therefore, the evaluation of the impact of frequently used cooking methods on a final quality of breakfast cereals meal is needed. The present study investigates how the two different methods of heating, conventional and microwave (MW) assisted, affect the carbohydrate content, profile and resulting glycemic index of so prepared food as well as the antioxidant activity of meals...

Cervical cancer recently has become more common among younger women in Japan. Diagnosing early-stage cancer is straightforward using cervical cytodiagnosis and histological diagnosis. However, postmenopausal endophytic cervical cancer and skip lesions in cervical adenocarcinoma are difficult to detect. We compared the maximum standardized uptake value (SUVmax) of 18F-fluorodeoxy-glucose positron emission tomography/computed tomography (PET/CT) for primary staging of cervical cancer and evaluated the relationship of the imaging findings to prognosis...

INTRODUCTION: First Nations/Métis populations develop diabetes earlier and at higher rates than other Canadians. The Canadian diabetes risk questionnaire (CANRISK) was developed as a diabetes screening tool for Canadians aged 40 years or over. The primary aim of this paper is to assess the effectiveness of the existing CANRISK tool and risk scores in detecting dysglycemia in First Nations/Métis participants, including among those under the age of 40. A secondary aim was to determine whether alternative waist circumference (WC) and body mass index (BMI) cut-off points improved the predictive ability of logistic regression models using CANRISK variables to predict dysglycemia...

Continuous glucose monitoring (CGM) systems allow patients with diabetes mellitus to closely track glucose concentrations over several days, identify trends in glucose levels, and avoid glucose excursions. This technology has not only advanced diabetes mellitus management but has increased patient safety through greater glycemic awareness. Due to these attributes, CGM is now being applied in therapeutic research as a pharmacodynamic tool to support early clinical drug development programs. However, to date only a handful of studies have utilized CGM in type 2 diabetes mellitus (T2DM) drug development...

High-resolution respirometry allows for the measurement of oxygen consumption of isolated mitochondria, cells and tissues. Beta cells play a critical role in the body by controlling blood glucose levels through insulin secretion in response to elevated glucose concentrations. Insulin secretion is controlled by glucose metabolism and mitochondrial respiration. Therefore, measuring intact beta cell respiration is essential to be able to improve beta cell function as a treatment for diabetes. Using intact 832/13 INS-1 derived beta cells we can measure the effect of increasing glucose concentration on cellular respiration...

While many naturally occurring polysaccharides have been widely used as drug carriers, there are two main drawbacks in their use: the first is their physical properties such as molecular weight, branching, type of glycosidic linkages and solubility depend on their source and the method of isolation and purification, the second is many of them are contaminated with proteins and protein removal is essential for preventing immune reactions. Synthetic polysaccharides on the other hand can be tailor made from their respective monomers with consistent physical properties and are, free from protein contamination, both being significant advantages in their use...

We synthesized Pt supported catalysts by the glucose assisted hydrothermal method, in which a carbon template was used to form a porous CeO2 structure upon calcination. Special emphasis was given to evaluate the influence of calcination parameters in the structural and textural properties of the catalysts and the final impact in the catalytic activity of CO oxidation reaction under hydrogen rich atmosphere (PROX-CO). We show that at 350 °C the carbon matrix was already mostly burnt and that higher temperatures and holding times mostly increase the CeO2 crystallite sizes...

In this paper, we develop a simple and facile approach to prepare graphene nanosheets through chemical reduction with glucose as reducing agent and modification agent. The reduced and modified graphene by glucose (denoted as g-rGO) was characterized with techniques of Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), Raman spectra, scanning electron microscopy (SEM) and transmission electron microscopy (TEM), etc. It is found that, besides the desired reduction capability to graphene oxide (denoted as GO), glucose plays an important role as a modifying reagent in stabilizing the as-prepared graphene nanosheets simultaneously and the g-rGO exhibits good dispersibility and stability in water and waterborne polyurethane matrix (denoted as WPU)...

Diabetes mellitus (DM) is a chronic metabolic disease and the subgroup of DM is called type II which is the most common form. The incidence of type II is increasing worldwide and it focuses on several new approaches to efficiently treatment of diabetes. Resveratrol (RSV) is known to be strong antioxidant and has an insulin-like effect in streptozotocin (STZ)-induced diabetic cells. It plays an active role at treatment of diabetes with reducing the oxidative stress, lowering glucose levels and protection of beta cells which are responsible for insulin secretion...
