Background There is an urgent need to identify natural bioactive compounds that can enhance gastrointestinal health and promote pig growth performance in the absence of pharmacological levels of zinc oxide(ZnO).The objectives of this study were to:1)compare the effects of mushroom powder supplemented with inorganic selenium(inSeMP)to mushroom powder enriched with organic selenium(orgSeMP)to pharmacological levels of ZnO on growth performance and faecal scores(FS)for the first 21 d post-weaning(Period 1);and 2)compare the molecular and microbial effects of inSeMP and orgSeMP in these pigs on d 39 post-weaning(Period 2).Methods In Period 1,pigs(3 pigs/pen;8 pens/treatment)were assigned to:(1)basal diet(control);(2)basal diet+zinc oxide(ZnO)(3100 mg/kg d 1–14,1550 mg/kg d 15–21);(3)basal diet+mushroom powder supplemented with inorganic selenium(inSeMP)containing selenium(selenite)content of 0.3 mg/kg feed;(4)basal diet+mushroom powder enriched with organic selenium(orgSeMP)containing selenium(selenocysteine)content of 0.3 mg/kg *** powders were included at 6.5 g/kg of *** In Period 1,there was no effect of diets on average daily gain(ADG)and gain:feed(G:F)ratio(P>0.05).The orgSeMP supplemented pigs had a lower average daily feed intake(ADFI)compared to all other groups(P0.05).The orgSeMP supplementation increased the caecal abundance of bacterial members of the Firmicutes and Bacteroidetes phylum,including Lactobacillus,Agathobacter,Roseburia,and Prevotella and decreased the abundance of Sporobacter compared to the basal group,while inSeMP increased the caecal abundance of Prevotella and decreased the caecal abundance of Sporobacter compared to the basal group(P<0.05).Dietary

NUMERICAL RECONSTRUCTION OF SMALL PERTURBATIONS IN THE ELECTROMAGNETIC COEFFICIENTS OF A DIELECTRIC MATERIAL

引用

Journal of Computational Mathematics 2014年第1期32卷 21-38页

作者： marion Darbas Stephanie Lohrengel LAMFA UMR CNRS 7252 - Universitd de Picardie Jules Verne Amiens France LMR EA 4535 - Universitd de Reims Champagne-Ardenne Reims France

The aim of this paper is to solve numerically the inverse problem of reconstructing small amplitude perturbations in the magnetic permeability of a dielectric material from partial or total dynamic boundary measurements. Our numerical algorithm is based on the resolution of the time-dependent Maxwell equations, an exact controllability method and Fourier inversion for localizing the perturbations. Two-dimensional numerical experiments illustrate the performance of the reconstruction method for different configurations even in the case of limited-view data.

Precipitation of metal oxide nanoparticles using a miniemulsion technique

引用

Particuology 2011年第5期9卷 502-505页

作者： marion Winkelmann Heike Petra Schuchmann Institute of Process Engineering in Life Sciences Section I: Food Process Engineering Karlsruhe Institute of Technology

A method to precipitate nanoparticles using a miniemulsion technique is described, in which miniemulsion droplets between 100 and 1000 nm in size serve as nanoreactors enabling both the control of particle formation and particle growth. The application of miniemulsion droplets to synthesise nanoparticles comprises three advantages： first, the size of the precipitated particles is limited by the reactant concentration within the emulsion droplet; second, particle agglomeration is prevented as nanoparticle collision outside the nanoreactor is avoided; and third, easy technical scale up can be realized by increasing emulsion volume and thus the number of nanoreactors, while local conditions within the reactors are not changed, The miniemulsion technique is an easy scalable process which allows defined synthesis of particles by precipitation reactions. The miniemulsion technique involves first the preparation of a stable water-in- oil miniemulsion by high pressure homogenisation. Whereas a water soluble reactant is provided within the aqueous droplets, another oilas well as water-soluble reactant can be introduced to the emulsion after homogenisation. The precipitation reaction is induced by the diffusion of the second reactant into the emulsion droplet. Together with this contribution, a method is described and discussed which uses a high pressure homogenisation process to produce stable water-in-oil miniemulsions serving as a reaction medium to precipitate metal oxides.

How a membrane agent buys goods in a membrane store

引用

Progress in Natural Science:Materials International 2007年第4期17卷 442-448页

作者： Rudolf Freund marion Oswald Thomas Schirk Institute of Computer Languages Vienna University of Technology Favoritenstr. 9 WienAustria

In this paper we consider a specific model of membrane systems, i. e. membrane systems with attributes. In these systems, the information is placed at the membranes in form of attributes, no objects are considered inside the membranes except for other membranes. The membrane system with attributes evolves according to rules that compute new values for the attributes from the attributes assigned to the membranes involved in the rule. The model of membrane systems with attributes allows us to specify business transactions in a precise way and to simulate different models for such transactions with a suitable tool for membrane systems with attributes.

作者： Arthur BOUSQUET Martine marion Roger TEMAM The Institute for Scientific Computing and Applied Mathematics Indiana University Département Mathématique Informatique Université de LyonEcole Centrale de Lyon

The authors consider a simple transport equation in one-dimensional space and the linearized shallow water equations in two-dimensional space, and describe and implement a multilevel finite-volume discretization in the context of the utilization of the incremental unknowns. The numerical stability of the method is proved in both cases.

PTEN in liver diseases and cancer

引用

World Journal of Gastroenterology 2010年第37期16卷 4627-4633页

作者： marion Peyrou Lucie Bourgoin Michelangelo Foti Department of Cellular Physiology and Metabolism Geneva Medical Faculty Centre Médical Universitaire

The phosphoinositide 3-kinase (PI3K)/phosphatase and tensin homolog (PTEN)/Akt axis is a key signal transduction node that regulates crucial cellular functions, including insulin and other growth factors signaling, lipid and glucose metabolism, as well as cell survival and apoptosis. In this pathway, PTEN acts as a phosphoinositide phosphatase, which terminates PI3Kpropagated signaling by dephosphorylating PtdIns(3,4)P2 and PtdIns(3,4,5)P3. However, the role of PTEN does not appear to be restricted only to PI3K signaling antagonism, and new functions have been recently discovered for this protein. In addition to the well-established role of PTEN as a tumor suppressor, increasing evidence now suggests that a dysregulated PTEN expression and/or activity is also linked to the development of several hepatic pathologies. Dysregulated PTEN expression/activity is observed with obesity, insulin resistance, diabetes, hepatitis B virus/hepatitis C virus infections, and abusive alcohol consumption, whereas mutations/deletions have also been associated with the occurrence of hepatocellular carcinoma. Thus, it appears that alterations of PTEN expression and activity in hepatocytes are common and recurrent molecular events associated with liver disorders of various etiologies. These recent f indings suggest that PTEN might represent a potential common therapeutic target for a number of liver pathologies.
