Biofilm formation by Escherichia coli contributes to the persistence of infections. In order deepen knowledge about pathogenesis E. infections, objective was assess biofilm production and expression virulence factors human clinical isolates from enteric urinary infections Argentina. We analyzed 105 diarrheagenic (DEC) uropathogenic (UPEC). All (except one) were producers. The moderate former (MBF) category prevalent (38.1%). Curli fimbriae most highly expressed factor (94.3%), whereas...
Abstract The cell envelope of Gram-negative bacteria belonging to the Burkholderia cepacia complex (Bcc) presents unique restrictions antibiotic penetration. As a consequence, Bcc species are notorious for causing recalcitrant multidrug-resistant infections in immunocompromised individuals. Here, we present results genome-wide screen envelope-associated resistance and susceptibility determinants cenocepacia clinical isolate. For this purpose, construct high-density, randomly-barcoded...
3 mol% yttria-partially stabilized zirconia (Y-TZP) powder and a sol-gel derived CaO-P 2 O 5 -SiO (64S) bioglass, were used to produce Y-TZP-bioglass slip cast compacts.The rheological properties of concentrated aqueous Y-TZP-64S suspensions prepared with two different glass contents: 10.5 vol% 19.9 vol%, ammonium polyacrylate (NH 4 PA) as dispersant, investigated compared those Y-TZP.The density green samples was related the degree dispersion.The substitution Y-TZP by 64S in mixtures...
Abstract The composition and morphology of bones implanted with stainless steel (316L‐SS) a metal alloy made zinc, aluminum, copper (Zinalco) are compared. Small‐angle X‐ray scattering (SAXS) nuclear magnetic resonance (NMR) results show that time Zinalco is corroded diffuse into the osseous tissue, promoting nonhomogeneous bone. Instead, 316L‐SS does not incorporate bone, bone recovers homogeneously at lower speed. © 2005 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 2006
Abstract Highly porous zirconia (ZrO 2 ) scaffolds fabricated by the replication method were coated with fluorapatite ( FA ). The coating was obtained dipping ZrO into stabilized aqueous slips having different viscosity values (≤5.0 mPa.s). influence of slip and immersion time on reduction in scaffold porosity microstructure investigated. Cell spreading survival bone marrow‐derived stromal cells BMSC pre‐osteoblastic MC 3T3‐E1 uncoated examined using fluorescence SEM microscopy, MTT...
The need to improve the surface properties of materials, has led development parts coated with hard materials deposited on substrates. In this work, by using finite element method AA Aluminium 6063 T6 hardness an error less 5 % Brinell (HBN), in comparison experimental data supplied, was determined. For this, modelling a spherical indentation test carried out, which loads and projected contact radius are obtained from several potential adjustments. Then, Lessage-Pertúz model Ni-P coating...
Abstract The cell envelope of the Gram-negative Burkholderia cepacia complex (Bcc) presents unique restrictions to antibiotic penetration. As a consequence, Bcc species are notorious for causing recalcitrant multidrug-resistant infections in immunocompromised individuals, such as those living with cystic fibrosis. To systematically identify envelope-associated resistance and susceptibility determinants at genome level, we constructed high-density, randomly-barcoded transposon mutant library...

Abstract Burkholderia contaminans, a species of the cepacia complex—prevalent in certain Latin-American and European countries—can cause chronic pulmonary infection persons with cystic fibrosis. Our aim was to gain insights into long-term lung infections focus on correlating how bacterial phenotypic traits impact patients’ clinical outcome. Genotypic characteristics 85 B. contaminans isolates recovered from 70 patients were investigated. For 16 those patients, status characteristics, e.g....
