AI Article Synopsis

  • The study examines how different chemical compositions in soda-lime silicate glasses impact their viscosity at various temperatures between 600 and 1300 °C.
  • The research evaluates the effects and interactions of major components like NaO, KO, CaO, MgO, and AlO on viscosity.
  • Additionally, it assesses the influence of trace elements such as BaO, BO, LiO, and F in the higher temperature range of 700 to 1300 °C.

Article Abstract

Published data are used to develop factors for predicting the viscosity-temperature relationship from the compositions of "soda-lime" type silicate glasses at specific temperatures in the range of 600 to 1300 °C. The effects of NaO, KO, CaO, MgO, AlO and their interactions are evaluated. The influence of minor amounts of BaO, BO, LiO, and F, in the temperature range of 700 to 1300 °C, is estimated.

High pressure processing, acidic and osmotic stress increased resistance to aminoglycosides and tetracyclines and the frequency of gene transfer among strains from commercial starter and protective cultures.

October 2022

CIISA-Centro de Investigação Interdisciplinar em Sanidade Animal, Faculdade de Medicina Veterinária, Universidade de Lisboa, Avenida da Universidade Técnica, 1300-477, Lisboa, Portugal.

This study analyzed the effect of food-related stresses on the expression of antibiotic resistance of starter and protective strains and resistance gene transfer frequency. After exposure to high-pressure processing, acidic and osmotic stress, the expression of genes encoding resistance to aminoglycosides (aac(6')Ie-aph(2″)Ia and aph(3')-IIIa) and/or tetracyclines (tetM) increased. After cold stress, a decrease in the expression level of all tested genes was observed.

Prevalence and Characterization of ESBL/AmpC Producing from Fresh Meat in Portugal.

Antibiotics (Basel)

November 2021

Laboratory of Bacteriology and Mycology, National Reference Laboratory of Animal Health, INIAV-National Institute of Agrarian and Veterinary Research, 2780-157 Oeiras, Portugal.

The present study aimed to characterize the extended-spectrum β-lactamases and plasmid-mediated AmpC β-lactamases (ESBL/PMAβ) among producers isolated from beef, pork, and poultry meat collected at retail, in Portugal. A total of 638 meat samples were collected and inoculated on selective medium for the search of resistant to 3rd generation cephalosporins. Isolates were characterized by antimicrobial susceptibility testing, molecular assays targeting ESBL/AmpC, plasmid-mediated quinolone resistance (PMQR), and plasmid-mediated colistin resistance (PMCR) encoding genes.
