A derivative spectrofluorimetric method for simultaneous determination of enrofloxacin (EFX) and ciprofloxacin (CFX) in cow milk was developed. The sample preparation based on rotating disk sorptive extraction (RDSE) using Oasis HLB® as phase followed by desorption the analytes with methanol. final extracts were evaluated spectrofluorimetry.

J774 macrophage-like cells express organic anion transporters that promote the efflux of fluoroquinolone antibiotics such as norfloxacin (NFX) from these cells. Gemfibrozil (GFZ) blocks organic anion transport in J774 cells, thereby facilitating the intracellular accumulation of NFX (Cao, C., H.C. Neu, and S.C. Silverstein. 1991. J. Cell Biol. 115:467a [Abstr.]). To determine whether GFZ enhanc...

A novel pressure sensor is investigated numerically. Operation of this sensor is determined by mechanical stresses and heat exchange. Estimation of deformations and heat transfer was done using programs ANSYS and ANSYS CFX. Numerical model was calibrated to fit experimental results. Conclusions about significance of heat exchange, thermal stresses and overall action of sensor were made. 1. Gene...

An experimental and numerical investigation into the tip leakage flow of a turbine rotor is carried out using a particle image velocimetry (PIV) system and the commercial software ANSYS CFX 14.0. The specimen used in this work is a typical GE-E3 model with a new squealer tip design. The experimental data are used to create a turbulence model and numerical strategy. Through the validated turbule...

PURPOSE Reports evaluating diagnosis and cross reactivity of quinolone hypersensitivity have revealed contradictory results. Furthermore, there are no reports investigating the cross-reactivity between gemifloxacin (GFX) and the others. We aimed to detect the usefulness of diagnostic tests of hypersensitivity reactions to quinolones and to evaluate the cross reactivity between different quinolo...

Abstract l -Cysteine coated zinc oxide (ZnO) nano hollow spheres were prepared as a potent drug delivery agent to eradicate Salmonella enterica serovar Typhimurium ( S. typhimurium ). The ZnO synthesized by following the environmentally-friendly trisodium citrate assisted method and -cysteine (L-Cys) conjugate with its surface. ZnO/L-Cys@CFX nanocarrier has been fabricated incorporating ceftizo...
