1Superior Properties of Mg–4Y–3RE–Zr Alloy Prepared by Powder Metallurgy显示文摘Magnesium alloys are important materials for application in the automotive and aviation industries. During the last few years, the number of possible applications as biodegradable implants in medicine has grown. Mg–RE(rare earth) alloys belong to the most advanced group of products, offering the best combination of mechanical properties and corrosion resistance. Among these materials, WE43(Mg–Y–Nd)is a very well-known commercial alloy that has been extensively studied for applications at increased temperatures and also in organisms. Although this material has been described, there are still possibilities to improve its properties and subsequently expand its applicability. Powder metallurgy has already been used for the preparation of magnesium alloys with superior mechanical properties and occasionally superior corrosion properties. Therefore, the present paper is oriented toward the preparation of Mg–4Y–3RE–Zr(WE43) alloy by the powder metallurgy technique(WE43-PM) and comparison of the final properties with the product of extrusion of as-cast ingot(WE43-IM). Our processing leads to a partial improvement in the mechanical properties and superior corrosion resistance of WE43-PM. The texture strength of WE43-PM was low, and therefore, anisotropy of mechanical properties was suppressed.Jirí Kubásek Drahomír Dvorsky Miroslav Cavojsky Dalibor Vojtěch Nad'a Beronská Michaela Fousová 2017Journal of Materials Science & Technology2017,33,7:4

8Effects of drinking water supplementation with Lactobacillus reuteri,and a mixture of reuterin and microcin J25 on the growth performance,caecal microbiota and selected metabolites of broiler chickens显示文摘Background:Since the overuse of antibiotics in animal production has led to a selection of antibiotic-resistant pathogens that affect humans and animals as well.Scientists are therefore searching for novel natural alternatives to antibiotics.In this study Lactobacillus reuteri and a combination of reuterin and microcin J25(RJ)were evaluated as promoters of growth and modulators of the cecal microbiota and metabolite profiles in broiler chickens.Oneday-old Cobb 500 male broilers were distributed to 8 treatments:negative control(without antibiotic),positive control(bacitracin),three concentrations of RJ and three doses of L.reuteri plus glycerol.The birds(2176,34 per pen,8 pens per treatment)were reared for 35 d.Results:The body weight of the bacitracin and 5 mmol/L reuterin combined with 0.08μmol/L microcin J25(10RJ)treatment group was significantly higher than that of the negative control group(P<0.05).L.reuteri had no significant effect on broiler growth.MiSeq high-throughput sequencing of 16S rRNA showed clustering of cecal microbial operational taxonomic unit diversity according to treatment.The influence of bacitracin and 10RJ on bacterial community overall structure was similar.They promoted Ruminococcaceae,Lachnospiraceae and Lactobacillaceae,increased the relative abundance of Faecalibacterium and decreased the abundance of Bacteroides and Alistipes,while the negative control condition favored Bacteroidaceae and Rikenellaceae.Furthermore,10RJ increased the concentration of short-chain fatty acid in the cecum and changed the metabolome overall.Conclusions:These overall suggest that 10RJ can promote a host-friendly gut environment by changing the cecal microbiome and metabolome.This combination of natural antimicrobial agents in the drinking water had a positive effect on broiler growth and may be suitable as an alternative to antibiotic growth promoters.Liya Zhang Laila Ben Said Nadège Hervé Séverine Zirah Moussa Sory Diarra Ismail Fliss 2022Journal of Animal Science and Biotechnology2022,13,4:1

17Synthesis of alkynes and alkynyl iodides bearing a protected amino alcohol moiety as functionalized amino acids precursors显示文摘Amino acid precursors in protected amino alcohol form are important synthons that can be used as building-blocks for the hemisynthesis of non-natural amino acids.Serine can be used as a common starting material for the synthesis of such compounds differently protected.Particularly,protected amino alcohols bearing an ethynyl and/or an iodoethynyl group can be used in cross-couplings,in 1,3-dipolar cycloadditions and/or in Nozaki-Hiyama-Kishi type reactions.We thus demonstrated that the efficiently protected amino alcohols derived from serine can be coupled to a sugar derivative by an indium mediated alkynylation reaction.The conditions of this coupling are compatible with such functionalized derivatives and allow envisaging an access to C-glycosylated amino acids.AYED Charfedinne PICARD Julien LUBIN-GERMAIN Nadège UZIEL Jacques AUGE Jacques 2010Science China Chemistry2010,53,9:1
