OBJECTIVES To characterize the prevalence of plasmid-mediated quinolone resistance determinants qnr and aac(6')-Ib-cr in extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae. METHODS qnrA, qnrB, qnrS, aac(6')-Ib-cr and ESBL-encoding genes were detected by PCR. MICs of 10 antimicrobial agents were determined by Etest. PFGE was used to investigate the clo...
The AAC [Austrian Academy Corpus] is a corpus research institution based at the Austrian Academy of Sciences in Vienna. The AAC is a very large and complex electronic text collection. Its aims are to create an innovative text corpus and to conduct scholarly and scientific research in the field of electronic text corpora. In the first phase of the corpus build up the AAC is committed to have at ...
BACKGROUND Acute acalculous cholecystitis (AAC) is generally considered to be a mild disease in children; however, if left untreated or treated without caution, AAC can lead to severe outcomes, such as death. The objectives of this study were to present the clinical features and identify the predictors of mortality in pediatric AAC. METHODS Patients diagnosed with AAC between 2005 and 2012 we...
The removal of plant pigments such as ?-carotene is an aspect vegetable oil processing often desired by the food and pharmaceutical industries. Adsorption to acid-activated clay (AAC) a well-established method for purification. Despite this, mechanism not well understood. UPLC-MS/MS analysis surface compounds extracted from ?-carotene-AAC (BC-AAC) complexes show that AAC acts oxidiser. Oxidatio...
Enzymatic modification of aminoglycosides by nucleotidyltransferases, acetyltransferases and/or phosphotransferases accounts for the majority of aminoglycoside-resistant Acinetobacter isolates. In this study, we investigated the relationship between aminoglycoside resistance and the presence of aminoglycoside-modifying enzymes in Acinetobacter baumannii clinical isolate groups with different re...
OBJECTIVES Traffic and ambient air pollution exposure are positively associated with cardiovascular disease, potentially through atherosclerosis promotion. Few studies have assessed associations of these exposures with thoracic aortic calcium Agatston score (TAC) or abdominal aortic calcium Agatston score (AAC), systemic atherosclerosis correlates. We assessed whether living close to a major ro...
Two mouse models of mammary cancer (a carcinoma and sarcoma) were examined using quantitative ultrasound (QUS). Scatterer property estimates, i.e., the average scatterer diameter (ASD) and average acoustic concentration (AAC), were estimated from regions-of-interest (ROIs) inside the tumors. Initially, the spherical Gaussian model was used over an analysis bandwidth of 10 to 25 MHz to obtain AS...
