recommendations! Published in 2017 at "Applied Surface Science"

DOI: 10.1016/j.apsusc.2017.07.009

Abstract: Abstract Zirconia/alumina ceramics possess outstanding mechanical properties for dental and orthopedic applications, but due to their poor surface bioactivities they exhibit a weak bone-bonding ability. This work proposes an effective 30-min solution treatment which could… read more here.

DOI: 10.1016/j.jeurceramsoc.2016.04.038

Abstract: Abstract The statistical fatigue strength evaluations in water of an intragranular type Ce-TZP/Al2O3 nanocomposite (Ce-TZP/A-N) were investigated in comparison to 3Y-TZP. The isothermal t-m transformation which causes low temperature aging degradation (LTAD) did not occur… read more here.

DOI: 10.1016/j.jeurceramsoc.2020.02.040

Abstract: Abstract 3Y-TZP ceramics are commonly used in restorative dentistry for fixed partial dentures, implants, abutments and root posts. The stress-induced transformation-toughening mechanism leads to improved mechanical properties advocating 3Y-TZP to be ground or sandblasted for… read more here.

DOI: 10.1021/acsami.7b03405

Abstract: Yttria-stabilized tetragonal zirconia (Y-TZP) has been proposed as a potential dental implant because of its good biocompatibility, excellent mechanical properties, and distinctive aesthetic effect. However, Y-TZP cannot form chemical bonds with bone tissue because of… read more here.

DOI: 10.1089/mdr.2019.0079

Abstract: This study aimed to determine the mechanism of resistance to piperacillin-tazobactam (TZP) in Klebsiella pneumoniae bloodstream isolates that are susceptible to extended-spectrum cephalosporins (ESCs). Antibiotic susceptibility was determined for K. pneumoniae isolated from children with… read more here.

recommendations! Published in 2020 at "Antimicrobial Agents and Chemotherapy"

DOI: 10.1128/aac.01899-20

Abstract: The rising frequency of multidrug-resistant and extensively drug-resistant (MDR/XDR) pathogens is making more frequent the inappropriate empirical antimicrobial therapy (IEAT) in nosocomial pneumonia, which is associated with increased mortality. We aim to determine the short-term… read more here.

DOI: 10.1159/000522259

Abstract: Background: Guidelines recommend empirical therapy with piperacillin/tazobactam (TZP) for spontaneous bacterial peritonitis (SBP) with low risk of multidrug-resistant organisms. Whether coverage of beta-lactam-resistant Gram-positive bacteria, such as ampicillin-resistant Enterococcus faecium, provides clinical benefit in such… read more here.
