OBJECTIVE: The effects of diets high in refined grains on biliary and colonic bile acids have been investigated extensively. However, the effects of diets high in whole versus refined grains on circulating bile acids, which can influence glucose homeostasis and inflammation through activation of farnesoid X receptor (FXR) and G protein-coupled bile acid receptor 1 (TGR5), have not been studied. MATERIALS AND METHODS: We conducted a secondary analysis from a randomized controlled crossover feeding trial (NCT00622661) in 80 healthy adults (40 women/40 men, age 18-45 years) from the greater Seattle Area, half of which were normal weight (BMI 18...

Endoplasmic reticulum (ER) stress is activated in non-alcoholic fatty liver disease (NAFLD), raising the possibility that ER stress-dependent metabolic dysfunction, inflammation and cell death underlie the transition from steatosis to steatohepatitis (NASH). Bax inhibitor-1 (BI-1), a negative regulator of the ER stress sensor IRE1α, has yet to be explored in NAFLD as a hepatoprotective agent. We hypothesized that the genetic ablation of BI-1 would render the liver vulnerable to NASH due to unrestrained IRE1α signaling...

The ability of microorganisms to use root-derived metabolites as growth substrates is a key trait for success in the rhizospheric niche. However, few studies describe which specific metabolites are consumed, or to what degree microbial strains differ in their substrate consumption patterns. Here we present an LC-MS exometabolomic study of three bacterial strains cultivated using either glucose or Arabidopsis thaliana root extract as the sole carbon source. Two of the strains were previously isolated from field-grown Arabidopsis roots, the other is Escherichia coli included as a comparison...

High fructose consumption is associated with metabolic disorders including hyperglycemia and dyslipidemia, in addition to endothelial dysfunction. Naringin, a flavonoid present in citrus fruit, has been reported to exhibit lipid lowering, antioxidant, and cardiovascular protective properties. Therefore, the present study investigated the effect of naringin on fructose-induced endothelial dysfunction in rats and its underlying mechanisms. Male Sprague-Dawley rats were given 10% fructose in drinking water for 12 weeks, whereas control rats were fed drinking water alone...

Diabetic nephropathy (DN) is one of the common microvascular complications of diabetes mellitus. Renal fibrosis is closely related to the deterioration of renal function. The present study aimed to investigate protective effect of Taxus chinensis on high-fat diet/streptozotocin-induced DN in rats and explore the underlying mechanism of action. The rat DN model was established via feeding high fat diet for 4 weeks and subsequently injecting streptozotocin (30 mg·kg-1 body weight) intraperitoneally. The rats with blood glucose levels higher than 16...

The objective of this study was to determine if feeding colostrum to newborn calves through an esophageal tube, compared with a nipple bottle, would delay abomasal emptying, which would in turn decrease passive transfer of IgG and plasma glucose, insulin, and glucagon-like peptide (GLP) 1 and GLP-2 concentrations. Twenty newborn Holstein bull calves were fed 3 L of colostrum replacer (200 g of IgG) through either an esophageal tube or nipple bottle at 2 h after birth followed by feeding pooled whole milk every 12 h after birth...

Eastern grey kangaroos (Macropus giganteus) younger than 19 months at Kanazawa Zoological Gardens, Japan, frequently died of enteritis. The main cause of death was coccidiosis. This study aimed to reveal retrospectively the clinical features of enteritis and factors contributing to its high occurrence. In addition, haematological and serum biochemical parameters in kangaroos younger than 24 months were analyzed. The findings suggested that enteritis occurrence was higher in 10- to 12-month-old kangaroos than other ages and during seasons with high temperature and humidity than during seasons with low temperature and humidity...

OBJECTIVE: Postprandial hypoglycemia is an infrequent but disabling complication of Roux-en-Y gastric bypass (RYGB) surgery. Controversy still exists as to whether the postprandial hyperinsulinemia observed is due to inherent changes in pancreatic β-cell mass or function or to reversible alterations caused by RYGB anatomy. We aimed to determine if gastric feeding or reversal of RYGB would normalize postprandial glucose and hormone excursions in patients with symptomatic hypoglycemia...

Prey selection governs species interactions and regulates physiological energetics of individuals and populations. Suspension-feeding bivalves represent key species in coastal and estuarine systems for their ecological and economic value. These animals are able to sort and selectively ingest nutritious microalgae from dilute and composite mixtures of particulate matter. This aptitude was suggested to be mediated by interactions between carbohydrates associated with the surface of microalgae and C-type lectins present in mucus covering the feeding organs although a direct, unequivocal, role of lectins in food sorting in bivalves remains elusive...

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...

Six polysaccharides were extracted from different parts (whole plants, roots and leaves) of Anoectochilus roxburghii and Anoectochilus formosanus (ARPs, ARPs-1, ARPs-2, AFPs, AFPs-1 and AFPs-2). Their primary characteristics were identified and their antidiabetic activities were evaluated in STZ-induced diabetic mice. Root polysaccharides (ARPs-1and AFPs-1) and leaf polysaccharides (ARPs-2 and AFPs-2) were distinct from each other in terms of the Mws, monosaccharide compositions and functional groups. Notably, the primary structures of ARPs and AFPs were similar to those of ARPs-1and AFPs-1, respectively...

BACKGROUND AND OBJECTIVE: Neonatal hypoglycemia is a common problem, often requiring management in the NICU. Nonpharmacologic interventions, including early breastfeeding and skin-to-skin care (SSC), may prevent hypoglycemia and the need to escalate care. Our objective was to maintain mother-infant dyads in the mother-infant unit by decreasing hypoglycemia resulting in NICU transfer. METHODS: Inborn infants ≥35 weeks' gestation with at least 1 risk factor for hypoglycemia were included...

Increasing the yield and the productivity in cell culture-based vaccine manufacturing using high-cell-density (HCD) cultivations faces a number of challenges. For example, medium consumption should be low to obtain a very high concentration of viable host cells in an economical way but must be balanced against the requirement that accumulation of toxic metabolites and limitation of nutrients have to be avoided. HCD cultivations should also be optimized to avoid unwanted induction of apoptosis or autophagy during the early phase of virus infection...

Ageing and obesity are two major risk factors for the development of type 2 diabetes (T2D). A chronic, low-grade, sterile inflammation contributes to insulin resistance and β-cell failure. Toll-like receptor-4 (TLR4) is a major pro-inflammatory pathway; its ligands as well as downstream signals are increased systemically in patients with T2D and at-risk individuals. In the present study we investigated the combined effects of high fat/high sucrose diet (HFD) feeding, ageing and TLR4-deficiency on tissue inflammation, insulin resistance and β-cell failure...

BACKGROUND: Children with long-chain fatty acid β-oxidation disorders (LCFAOD) presenting with clinical symptoms are treated with a specialist infant formula, with medium chain triglyceride (MCT) mainly replacing long chain triglyceride (LCT). It is essential that the safety and efficacy of any new specialist formula designed for LCFAOD be tested in infants and children. METHODS: In an open-label, 21-day, phase I trial, we studied the safety of a new MCT-based formula (feed 1) in six well-controlled children (three male), aged 7-13 years (median 9 years) with LCFAOD (very long chain acyl CoA dehydrogenase deficiency [VLCADD], n=2; long chain 3-hydroxyacyl CoA dehydrogenase deficiency [LCHADD], n=2; carnitine acyl carnitine translocase deficiency [CACTD], n=2)...

Although epidemiological data and results from rodent studies support an inverse relationship between nicotine consumption and body weight, the molecular mechanisms are poorly understood. CD-1 mice were fed a basal diet or a basal diet containing low or high dose smokeless tobacco blend or high dose nicotine tartrate for 14 weeks. High dose tobacco blend and nicotine tartrate diets vs. basal diet reduced mouse body weight (16.3% and 19.7%, respectively), epididymal (67.6% and 72.5%, respectively) and brown adipose weight (42% and 38%, respectively), epididymal adipocyte size (46...

This study aimed to evaluate the effects of metabolic syndrome (MetS) induced by high-carbohydrate high-fat (HCHF) diet on bone mineral density (BMD), histomorphometry and remodelling markers in male rats. Twelve male Wistar rats aged 12 weeks old were randomized into two groups. The normal group was given standard rat chow while the HCHF group was given HCHF diet to induce MetS. Abdominal circumference, blood glucose, blood pressure, and lipid profile were measured for the confirmation of MetS. Bone mineral density, histomorphometry and remodelling markers were evaluated for the confirmation of bone loss...

BACKGROUND: The pathophysiologic processes underlying the regulation of glucose homeostasis are considerably complex at both cellular and systemic level. A comprehensive and structured specification for the several layers of abstraction of glucose metabolism is often elusive, an issue currently solvable with the hierarchical description provided by multi-level models. In this study we propose a multi-level closed-loop model of whole-body glucose homeostasis, coupled with the molecular specifications of the insulin signaling cascade in adipocytes, under the experimental conditions of normal glucose regulation and type 2 diabetes...
