An 8-week feeding trial was conducted to evaluate the effects of dietary lipid sources on growth performance, fatty acid composition, rate-limiting enzyme activities and gene expression related to lipid metabolism in large yellow croaker (Larmichthys crocea). Five iso-nitrogenous and iso-lipidic experimental diets were formulated to contain different lipid sources, such as fish oil (FO), soybean oil (SO), linseed oil (LO), rapeseed oil (RO) and peanut oil (PO), respectively. Triplicate groups of 50 fish (initial weight 13...

To reduce the distillation costs of cellulosic ethanol, it is necessary to produce high sugar titers in the enzymatic saccharification step. To obtain high sugar titers, high biomass loadings of lignocellulose are necessary. In this study, to overcome the low saccharification yields and the low operability of high biomass loadings, a fed-batch saccharification process was developed using an enzyme reactor that was designed and built in-house. After optimizing the cellulase and biomass feeding profiles and the agitation speed, 132...

Effectors of the phosphoinositide 3-kinase (PI3K) signal transduction pathway contribute to the hypothalamic regulation of energy and glucose homeostasis in divergent ways. Here we show that CNS action of the PI3K signaling intermediate atypical protein kinase C (aPKC) constrains food intake, weight gain, and glucose intolerance in both rats and mice. Pharmacologic inhibition of CNS aPKC activity acutely increases food intake and worsens glucose tolerance in chow-fed rodents and causes excess weight gain during high fat diet (HFD) feeding...

Heme oxygenase-1 (HO-1) is the inducible isoform of the heme oxygenase system, which catalyzes heme degradation. Up-regulation of this enzyme under pathological conditions is associated with beneficial effects in the whole organism. However, the potential of HO-1 in the alleviation of disturbances induced by a high-fat diet (HFD) is poorly elucidated. The present study was undertaken to determine the effects of pharmacological activation of HO-1 by hemin on some hormones and metabolic parameters in rats fed an HFD for 8 weeks...

REVIEW
Bàrbara Reynés, Mariona Palou, Andreu Palou
It is generally assumed that high-fat (HF) diets induce characteristic gene expression regulation, which may cause metabolic alterations associated with an increased risk of obesity, metabolic syndrome and other health alterations. However, an integrative analysis of the effects in different tissues is lacking, thus preventing new strategies to prevent or counteract permanent consequences. This review particularly focuses on lipid metabolism gene expression modulation in key homeostatic tissues in response to HF diet intake...

The patient is a 1-week-old boy born at 37+2 weeks' gestational age through spontaneous vaginal delivery. The pregnancy was complicated by maternal gestational diabetes mellitus and pre-eclampsia. The Apgar score was 9 at both 1 minute and 5 minutes after birth. Because of hypoglycemia at delivery that required IV dextrose, he was admitted to the local neonatal intensive care unit. His blood glucose levels quickly stabilized, dextrose administration was discontinued, and the patient began breast-feeding. On day 2 of life, the patient began having intermittent oxygen desaturation, with oxygen saturation as measured by pulse oximetry down to 70% while sleeping; he was transferred to a tertiary-care NICU for further management...

In this study, we investigated chmemoenzymatic synthesis of amylose-grafted poly(γ-glutamic acid) (PGA) as a new artificial saccharide-peptide conjugate composed of two biological macromolecules. Maltooligosaccharide as a primer of enzymatic polymerization by phosphorylase catalysis was first introduced on the PGA main chain by the condensation reaction using the condensing agent in NaOH aq. Thermostable phosphorylase-catalyzed enzymatic polymerization of α-d-glucose 1-phosphate (G-1-P) as a monomer was then performed from the primer chain ends of the product to obtain amylose-grafted PGAs, which formed hydrogels in reaction media depending on the G-1-P/primer feed ratios...

Sixty-four barrows with an initial body weight of 59.8 ± 2.1 kg were allocated to one of the two feeding frequency regimes (had free access to diet and fed two meals per day). Pigs had free access (FA) to feed were fed on an ad libitum basis during the 8-week experimental period. Pigs fed twice daily (M2) were allowed to consume their meals in 2 h. Pigs fed twice daily had lower average daily feed intake (p < 0.01) and average daily gain (p < 0.1), but a greater G:F (p < 0.05) than FA pigs...

Nutrient utilization, body condition and carcass traits of cull ewes were studied in three dietary regimens based on complete feed block (CFB) feeding to control (C) with rumen protected protein (RPP), CU [RPP + urea (6 g/kg)] and CUF [RPP + urea + rumen protected fat (RPF; 40 g/kg)]. The RPP component (g/kg) in C had 1% formaldehyde-treated soy flakes 50, mustard cake 50 and sesame cake 30. The mustard and sesame cakes were replaced with urea on equivalent N basis in CU and CUF. The ewes were offered ad libitum CFB composed (g/kg) of concentrate 650, roughage 300 and molasses 50...

OBJECTIVE: Obesity is associated with insulin resistance and adipose tissue inflammation. Reactive oxygen species (ROS) increase in adipose tissue during the development of obesity. We previously showed that in response to excess nutrients like glucose and palmitate, adipocytes generated ROS via NADPH oxidase (NOX) 4, the major adipocyte isoform, instead of using mitochondrial oxidation. However, the role of NOX4-derived ROS in the development of whole body insulin resistance, adipocyte inflammation, and recruitment of macrophages to adipose tissue during the development of obesity is unknown...

Ceriporiopsis subvermispora is a selective white-rot fungus that degrades lignin at a site far from the hyphae and extracellular enzymes, without intensive damage to the cellulose. In selective ligninolysis, low molecular mass metabolites play a principal role and amphipathic substances are involved to control the degradation and transport of hydrophobic aromatic molecules, including lignin and lipids; however, secretion of the amphipathic substances by this fungus has not been well understood, except for alk(en)yl itaconates called ceriporic acids, which have a weak amphiphilicity...

Non-pharmacological early weaning (NPEW) leads offspring to obesity, higher liver oxidative stress and microsteatosis in adulthood. Pharmacological EW (PEW) by maternal treatment with bromocriptine (BRO) causes obesity in the adult progeny but precludes hepatic injury. To test the hypothesis that BRO prevents the deleterious changes of NPEW, we injected BRO into the pups from the NPEW model on late lactation. Lactating rats were divided into 2 groups: dams with an adhesive bandage around the body to prevent breastfeeding on the last 3 days of lactation and dams whose pups had free suckling (C)...

The present study aimed to investigate the inhibitory effect of chamomile decoction extract (CDE) on intestinal glucose absorption as well as its protective role against high fat diet (HFD)-induced obesity and lipotoxicity in rats. We used the Ussing chamber system to investigate the effect of CDE on intestinal transport of glucose. Male Wistar rats were fed HFD for six weeks to provoke obesity. CDE (100mg/kg, b.w. p.o.) has been per orally administered to HFD fed rats. Ex vivo, we found that CDE significantly and dose-dependently increased intestinal absorption of glucose...

Projections on the profitability of the pharmaceutical industry predict a large amount of growth in the coming years. Stagnation over the last 20 years in product development has led to the search for new processing methods leading to improvements in profitability by the reduction of operating costs or the improvement of process productivity. This work proposes a novel multi-feed bioreactor system composed of independently controlled feeds for substrate(s) and media used as a supplement and allows for the free manipulation of the bioreactor supply rate and substrate concentrations to maximize bioreactor productivity and substrate utilization while reducing operating costs...

Melanin concentrating hormone (MCH) is a hypothalamic neuropeptide with a well-characterised role in energy homeostasis and emergent roles in diverse physiologic functions such as arousal, mood and reproduction. Work to date has predominantly focused on its hypothalamic functions using animal models however little attention has been paid to its role in circulation in humans. The aims of this study were to a) develop a radioimmunoassay for the detection of MCH in human plasma; b) establish reference ranges for circulating MCH; and c) characterize the pattern of expression of circulating MCH in humans...

Small intestinal starch digestion (SISD) in cattle is often limited; however, greater postruminal flow of high-quality protein (e.g., casein) can increase SISD, and Glu can mimic responses to casein for SISD. We evaluated effects of increasing Glu flows to the duodenum on SISD and N retention in cattle. Cattle received (DM basis) continuous duodenal infusion of raw cornstarch (1.5 ± 0.08 kg/d) and 0, 30.9 ± 0.6, 62.4 ± 1.2, or 120.4 ± 3.4 g/d Glu or 387.9 ± 17.5 g/d casein. As expected, the positive control (i...

Congenital hyperinsulinism (CHI) is a rare condition that can cause irreversible brain damage during the neonatal period owing to the associated hypoglycemia. Hypoglycemia in CHI occurs secondary to the dysregulation of insulin secretion. CHI has been established as a genetic disorder of islet-cell hyperplasia, associated with a mutation of the ABCC8 or KCNJ11 genes, which encode the sulfonylurea receptor 1 and the inward rectifying potassium channel (Kir6.2) subunit of the ATP-sensitive potassium channel, respectively...

BACKGROUND: Ageing and type 2 diabetes mellitus (T2DM) are risk factors for skeletal muscle loss. We investigated whether anabolic resistance to feeding might underlie accelerated muscle loss in older people with T2DM and whether dysregulated mTOR signalling was implicated. SUBJECTS: 8 obese men with T2DM, and 12 age-matched controls were studied (age 68 ± 3 vs. 68±6 y; BMI: 30 ± 2 vs. 27 ± 5 kg m(-2)). METHODS: Body composition was measured by dual-X-ray absorptiometry...
