Widespread distribution of CTX-M and plasmid-mediated AmpC β-lactamases in Escherichia coli from Brazilian chicken meat

open access: yesMemorias do Instituto Oswaldo Cruz, 2015
The dissemination of plasmid-mediated antimicrobial resistance genes may pose a substantial public health risk. In the present work, the occurrences ofblaCTX-M and plasmid-mediated ampCand qnrgenes were investigated in Escherichia colifrom 16 chicken ...

Blaschke's problem for timelike surfaces in pseudo-Riemannian space forms

open access: yes, 2011
We show that isothermic surfaces and S-Willmore surfaces are also the solutions to the corresponding Blaschke's problem for both spacelike and timelike surfaces in pseudo-Riemannian space forms.

Tryptophan derivatives as non‐invasive diagnostic indicators for obesity‐related MASLD in children and adolescents

open access: yesDiabetes, Obesity and Metabolism, Volume 27, Issue 12, Page 7544-7560, December 2025.
Abstract Aims Metabolic dysfunction‐associated steatotic liver disease (MASLD) represents a major health burden in children and adolescents with obesity. This study aimed to characterize metabolic alterations associated with obesity‐related MASLD and to evaluate the potential of tryptophan (TRP)‐derived metabolites as non‐invasive biomarkers for early ...

Frequency of Plasmid-Mediated Quinolone-Resistance (qnr) Genes in Pseudomonas aeruginosa Strains Isolated from Hospitalized Patients [PDF]

open access: yesJournal of Mazandaran University of Medical Sciences
Background and purpose: Quinolones and fluoroquinolones are used to treat infection with resistant strains of Pseudomonas aeruginosa; however, the inappropriate use of antibiotics regardless of resistance patterns has led to the emergence of new and ...

New qnr Gene Cassettes Associated with Superintegron Repeats in Vibrio cholerae O1

open access: yesEmerging Infectious Diseases, 2008
A novel qnr determinant emerged in ciprofloxacin-resistant Vibrio cholerae O1 from the Amazon region of Brazil. This qnrVC1 was in a typical class 1 integron. Its attC showed 89% identity with V. parahaemolyticus superintegron repeats. Analysis showed V.

Instability in a Vlasov-Fokker-Planck binary mixture

open access: yes, 2018
This paper is concerned with a kinetic model of a Vlasov-Fokker-Planck system used to describe the evolution of two species of particles interacting through a potential and a thermal reservoir at given temperature.

EVALUATION OF PLASMID-MEDIATED QUINOLONE RESISTANCE ASSOCIATED WITH THE QNR GENES IN CLINICAL ISOLATES OF SHIGELLA SPP. IN BAGHDAD

open access: yesThe Iraqi Journal of Medical Sciences, 2016
Background:Although quinolone resistance results mostly from chromosomal mutations in Enterobacteriaceae, it may also be mediated by plasmid-encoded qnr determinants. Shigella harboring the novel qnr plasmid-mediated mechanism of quinolone resistance has

Evaluation of the Susceptibility profiles, genetic similarity and presence of qnr gene in Escherichia coli resistant to ciprofloxacin isolated in Brazilian hospitals

open access: yesBrazilian Journal of Infectious Diseases
Increasing quinolone resistance has been reported worldwide, mainly among clinical isolates of Escherichia coli. The objectives of this study were to determine the susceptibility profile, the genetic relatedness, and the prevalence of the qnr gene among ...

Fields with the Bogomolov property [PDF]

open access: yes, 2013
A field is said to have the Bogomolov property relative to a height function h’ if and only if h’ is either zero or bounded from below by a positive constant for all for all elements in this field.

High prevalence of plasmid-mediated quinolone resistance determinants in Enterobacter cloacae isolated from hospitals of the Qazvin, Alborz, and Tehran provinces, Iran

open access: yesRevista da Sociedade Brasileira de Medicina Tropical, 2016
: INTRODUCTION: Plasmid-mediated quinolone resistance (PMQR) is a growing clinical concern worldwide. The main aims of this study were to detect qnr-encoding genes and to evaluate the clonal relatedness of qnr-positive Enterobacter cloacae isolates ...
