Changes in gut microbiota (GM) are closely associated with metabolic syndrome, obesity, type 2 diabetes and so on. Several medicinal herbs, including Ephedra sinica (Es), have anti-obesity effects that ameliorate metabolic disorders. Therefore, in this study we evaluated whether Es maintains its anti-obesity effect through Es-altered gut microbiota (EsM) transplantation. GM was isolated from cecal contents of Es treated and untreated rats following repeated transplants into obese rats via oral gavage over three weeks...

Birds have been used intensively as biomonitors of halogenated flame retardants (HFRs), and several studies have reported elevated tissue concentrations and inter-individual variability for these contaminants. While diet is known to be an important exposure pathway for HFRs in birds, it has been suggested that exposure through air may represent an underestimated source of HFRs for certain species. However, a method was not available for measuring the atmospheric exposure of individual birds to HFRs or other semi-volatile contaminants...

Previous reports on the inverse association between ‘mate’ intake (infusion of Ilex Paraguariensis herb) and breast cancer (BC) risk led us to consider two main roles for the infusion: as a substantial antioxidant contributor and as a hormone regulator, particularly through anti-aromatase capacities. Since menstrual-reproductive risk factors for BC reflect women’s estrogenic exposure during the reproductive lifespan, and considering that ‘mate’ intake exerts putative stronger protection among high antioxidant contributors, we attempted to analyze interactions among the infusion, hormon-linked reproductive factors and BC risk, which have hitherto remained unexplored...

Hydroxytyrosol is a polyphenol with antioxidant, metabolism-regulatory, anti-inflammatory and immuno-modulatory properties. The present study aimed to determine whether supplementing the maternal diet with hydroxytyrosol during pregnancy can improve pre- and early post-natal developmental patterns and metabolic traits of the offspring. Experiment was performed in Iberian sows fed a restricted diet in order to increase the risk of IUGR. Ten sows were treated daily with 1.5 mg of hydroxytyrosol per kg of feed between Day 35 of pregnancy (30% of total gestational period) until delivery whilst 10 animals were left untreated as controls...

BACKGROUND: Ganglioside GM3 is an abundant constituent of the plasma membrane where its accumulation attenuates insulin receptor signaling. Considering the role of skeletal muscles for insulin-stimulated glucose uptake, the aim of this study was to determine the expression of GM3 and its precursors in skeletal muscle of diabetes mellitus type 1 (DM1) and type 2 (DM2) rat models. METHODS: Diabetes was induced by streptozotocin (55 mg/kg for DM1 and 35 mg/kg for DM2) injection to male Sprague-Dawley rats which were fed with normal pellet diet (DM1 type) or high-fat diet (DM2 type)...

OBJECTIVE: Macrophages are believed to play a critical role in the inflammation associated with the development of osteoarthritis (OA) in obesity. The objective of the study was to investigate whether short-term, systemic depletion of macrophages would mitigate OA following injury in obese mice. METHODS: CSF-1R-GFP(+) Macrophage Fas-Induced Apoptosis (MaFIA) transgenic mice that allow conditional depletion of macrophages were placed on a high-fat diet and underwent surgery to induce knee OA...

SCOPE: In recent years, several studies reported the role of eIF4E-binding proteins (4E-BPs) on the development of diet-induced obesity and insulin resistance. Our aim was to investigate the effect of 4E-BP protein deletion on lipid accumulation and metabolism in skeletal muscle in response to a high fat diet-induced obesity in 4E-BP1/2 DKO mice. METHODS AND RESULTS: Diet-induced obesity engendered increased ectopic accumulation of lipotoxic species in skeletal muscle of 4E-BP1 and 4E-BP2 double-knockout mice (4E-BP1/2 DKO), namely diacylglycerols and ceramides...

The purpose of this study was to investigate the effect of radiation on the content of animal diet constituents using global metabolomics. Aqueous methanolic extracts of control and cobalt-60 irradiated NIH 7001 diets were comprehensively analyzed using nanoLC-MS/MS. Among the over two thousand ions revealed by XCMS followed by data preprocessing, 94 positive and 143 negative metabolite ions had greater than 1.5 fold changes and p-values <0.01. Use of Metaboanalyst statistical software demonstrated complete separation of the irradiated and non-radiated diets in unsupervised principal components analysis and supervised partial least squares discriminant analysis...

The cuprizone model of demyelination is well established in the mouse as a tool for the study of the mechanisms of both demyelination and remyelination. It is often desirable, however, to have a larger model, such as the rat, especially for imaging-based studies, yet initial work has failed to show demyelination in cuprizone-fed rats. Several recent studies have demonstrated demyelination in the rat, but only in the corpus callosum. In this study, we acquired high-resolution, three-dimensional images of the whole brain every 2 weeks, using a T1 -weighted magnetization-prepared rapid acquisition gradient echo imaging sequence, optimized for myelin contrast, in order to assess myelination across the entire rat brain over a period of 8 weeks on a 1% cuprizone diet...

AIMS: Ghrelin is implicated in the control of energy balance and glucose homeostasis. The ghrelin receptor exhibits ligand independent constitutive activity, which can be pharmacologically exploited to induce inverse ghrelin actions. Since ghrelin receptor inverse agonists (GHSR-IA) might be effective for the treatment of obesity-related metabolic disease, we tested two novel synthetic compounds GHSR-IA1 and GHSR-IA2. MATERIALS AND METHODS: In functional cell assays, electrophysiogical and immunohistochemical experiments, we demonstrated inverse agonist activity for GHSR-IA1 and GHSR-IA2...

The hyperphosphorylation of tau in the hippocampus can be caused by central and peripheral insulin resistance and these alterations are related to the development of tauopathies, such as Alzheimer's disease. In this study, we used a high-fat diet to induce obesity and insulin resistance in adult Swiss mice and checked whether supplementation with Myrciaria jaboticaba berry peel for 10 weeks could improve insulin sensitivity, learning/memory performance and prevent tau phosphorylation in the hippocampus. Furthermore, adipocytokines, inflammatory markers, and oxidative stress were assessed...

BACKGROUND: Older people are sometimes challenged in maintaining a healthy diet but, because of age and disadvantage, are also more vulnerable to the adverse health consequences of poor nutrition. It has been claimed that older adults have low levels of health literacy regarding food and struggle to discern which foods are healthy from the vast range available in developed counties (Br Herne 1995;97:12). However, nutrition and eating behaviour are modifiable risk factors for health in old age (Appl Physiol Nutr Keller 2007;32:991) and health benefits can accrue from promoting healthy eating later in life...

BACKGROUND: Adverse food reaction (AFR) is an important differential diagnosis for the pruritic dog. It is usually diagnosed by feeding an elimination diet with a novel protein and carbohydrate source for eight weeks followed by subsequent food provocation. A previous study demonstrated that patch testing dogs with foods had a high sensitivity and negative predictability for selection of elimination diet ingredients. HYPOTHESIS/OBJECTIVES: The aim of this study was to investigate patch testing with proteins, carbohydrates and dry commercial dog food in dogs to determine whether there was value in patch testing to aid the diagnosis of canine adverse food reaction...

AIMS AND OBJECTIVES: To map and describe key information in existing research about counselling of parents of children aged 0-2 years on the child's healthy diet in preventive health care settings, particularly in public health nursing. BACKGROUND: Many parents are likely to be concerned with their infant's food-related happiness "here and now", disregarding the child's long-term health and development related to feeding practices. Hence, a focus on counselling parents in considering young children's healthy diet is important...

The pine weevil (Hylobius abietis), a major pest of conifer forests throughout Europe, feeds on the bark and cambium, tissues rich in terpenoid resins that are toxic to many insect herbivores. Here we report the ability of the pine weevil gut microbiota to degrade the diterpene acids of Norway spruce. The diterpene acid levels present in ingested bark were substantially reduced on passage through the pine weevil gut. This reduction was significantly less upon antibiotic treatment, and supplementing the diet with gut suspensions from untreated insects restored the ability to degrade diterpenes...

Protein restriction during gestation can alter the skeletal muscle phenotype of offspring; however, little is known with regard to whether this also affects the neuromuscular junction (NMJ), as muscle phenotype maintenance depends upon NMJ functional integrity. This study aimed to evaluate the effects of a low protein (6%) intake by dams throughout gestation on male offspring NMJ morphology and nicotinic acetylcholine receptor (nAChR) α1, γ and ε subunit expression in the soleus (SOL) and extensor digitorum longus (EDL) muscles...
