The activities of pyruvate carboxylase (PC), phosphoenolpyruvate carboxykinase (PEPCK), glucose-6-phosphatase (GGPase), and glycogen synthetase (GS) were determined in the cancerous and in the apparently uninvolved (host) regions of livers from primary hepatoma patients as well as in normal adult human livers and human fetal livers. The activities of these enzymes were also assayed in a fairly ...

OBJECTIVE Quinolone resistance is usually caused by various chromosomal mutations, but has been more recently associated with plasmids which carry the qnr determinant. The aim of this study is to investigate the prevalence of qnr genes in clinical isolates of Enterobacteriaceae in Jamaica. METHODS A total of 255 non-duplicate fluoroquinolone-resistant Enterobacteriaceae clinical isolates, com...

WCK 771 demonstrated MIC(50) and MIC(90)s of 0.03 and 1 microg/ml, respectively, against 297 recent U.S. community-acquired and hospital strains of Staphylococcus aureus, irrespective of quinolone or glycopeptide resistance. Against quinolone-resistant strains, MIC(90)s of WCK 771 and moxifloxacin were 1 and 16 microg/ml, respectively.

The activities of pyruvate carboxylase (PC), phosphoenolpyruvate carboxykinase (PEPCK), glucose-6-phosphatase (GGPase), and glycogen synthetase (GS) were determined in the cancerous and in the apparently uninvolved (host) regions of livers from primary hepatoma patients as well as in normal adult human livers and human fetal livers.

Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most frequent neurologic complications experienced by patients receiving antineoplastic drugs. Involvement of the peripheral nerves may have an important impact on daily activi-ties and lead to severe impairment of the patient's quality of life (QoL). It seems to be of crucial importance to make a correct and early diagnosis of pol...

Benzo[/]-3-[(p-chlorophenylamino)(hydrazino)methyl]-4-hydroxy-1,2-dihydro-2-quinolone was prepared by the addition of H Br on — CH=N bond of the Schiff base followed by condensation with hydrazine and was used in the synthesis of different substituted triazolines borne on a quinolone moiety giving rise to a system of high probability to be of great biological importance. Some other derivatives ...

The purpose of this study was to determine the prevalence and molecular characterization of plasmid-mediated quinolone resistance (PMQR) genes (qnrA, qnrB, qnrS, aac(6')-Ib-cr, and qepA) among ESBL-producing Klebsiella pneumoniae isolates in Kashan, Iran. A total of 185 K. pneumoniae isolates were tested for quinolone resistance and ESBL-producing using the disk diffusion method and double disk...

An outbreak of Enterobacter cloacae infections with variable susceptibility to fluoroquinolones occurred in the University Medical Center Utrecht in the Netherlands in 2002. Our investigation showed that a qnrA1 gene was present in 78 (94%) of 83 outbreak isolates and that a qnrA1-encoding plasmid transferred to other strains of the same species and other species. The earliest isolate carrying ...

Quinolone resistance in clinical isolates of Campylobacter jejuni in Sweden increased more than 20-fold at the beginning of the 1990s. Resistance to 125 microgram of ciprofloxacin per ml in clinical isolates was associated with chromosomal mutations in C. jejuni leading to a Thr-86-Ile substitution in the gyrA product and a Arg-139-Gln substitution in the parC product.
