It is a non-destructive, quasi in situ method to determine profiles of the thickness and the chemical composition of passivation layers in trenches up to an aspect ratio of about 3. The performance of this technique to quantify the passivation layer thickness is compared to a standard technique using secondary electron microscopy images with respect to two different samples and is found to be at least equivalent. The possible uncertainties

and limitations of this technique are discussed as well. (C) 2012 American Institute of Physics. []“
“A total of 154 samples of skin lesions were obtained from dogs with superficial pyoderma that were assisted by the Veterinary Dermatology Service

click here at the University Veterinary Hospital (HVU), Universidade Federal de Santa Maria (UFSM), aiming to determine the antimicrobial susceptibility of Staphylococcus spp. isolates and evaluate the presence of multidrug resistance profile. After bacterial isolation and identification, the strains were tested for antimicrobial susceptibility, and the results showed lower percentages of resistance to the amoxicillin and clavulanic acid association (1.9%), cefadroxil (1.9%), cephalexin (1.9%) and vancomycin (0.6%). The highest percentages were towards amoxicillin (60.4%) and penicillin G (60.4%). The multidrug resistance was detected in 23.4% JQ1 research buy and the methicillin resistance in 5.8% of the samples. It may be concluded that the Staphylococcus spp. isolates present high susceptibility to key antimicrobials used in the treatment of superficial pyodermas in dogs at the HVU-UFSM, such as cephalexin and the amoxicillin and clavulanic acid association, confirming the preference for these drugs when treating dogs with this disorder. The susceptibility of the strains to fluoroquinolones, also recommended in the literature for the treatment of pyodermas, allows suggesting that such drugs

GANT61 mw should not be considered in the empirical selection. The identification of multidrug-resistant Staphylococcus spp. in the studied canine population justifies periodic and regional bacteriological tests of skin lesions in dogs with superficial pyoderma, possible therapeutic failures and also motivates wise use of antimicrobial therapy.”
“Background: Inorganic mesoporous materials exhibit good biocompatibility and hydrothermal stability for cell immobilization. However, it is difficult to encapsulate living cells under mild conditions, and new strategies for cell immobilization are needed. We designed a “fish-in-net” approach for encapsulation of enzymes in ordered mesoporous silica under mild conditions. The main objective of this study is to demonstrate the potential of this approach in immobilization of living cells.
