Objective: The effect of ceftazidime on Pseudomonas aeruginosa, with or without application of 1 MHz therapeutic ultrasound, was studied. Method: An aqueous suspension of microorganisms in a sterile, sealed plate was placed in an ultrasonic tank operating at 1 MHz. Different power outputs were used. After desired time of exposure to the ultrasound, each sample was plated separately and aft...

Introduction: Ozone affects blood oxygen transport and the pro-oxidant-antioxidant balance. However, role of formed elements gas transmitters in these processes still remains unclear. The aim present study was to investigate effect ozone on balance a red cell suspension. Methods: suspension incubated with at concentration 6 mg/l substances affecting synthesis (nitroglycerin, sodium hydrosulfide...

The object of the present work was formulation and in vitro evaluation of 5-Fluorouracil nanoparticles incorporated in sucralfate suspension as drug delivery system. Sucralfate acts as the cytoproytective agent and carry the antineoplastic drug loaded nanoparticles to the carcinoma site in the g .i.t which will protect and alleviate the carcinoma. 5-Fluorouracil nanoparticles were prepared by n...

Cell adhesion to fibronectin is known to confer a temporally related cell adhesion-mediated drug resistance (CAM-DR). However, it is unknown whether cell adhesion during drug selection influences the more permanent form of acquired drug resistance. To examine this question, we compared the acquisition of mitoxantrone resistance in U937 cells adhered to fibronectin versus cells selected in a tra...

Vortical cross-step filtration in suspension-feeding fish has been reported recently as a novel mechanism, distinct from other biological and industrial filtration processes. Although crossflow passing over backward-facing steps generates vortices that can suspend, concentrate, and transport particles, the morphological factors affecting this vortical flow have not been identified previously. I...

With regenerative braking technology reaching maturity manufacturers are studying other forms of energy regeneration, amongst these, regenerative suspension. Although there have been several regenerative shock absorber developments over the past decade, including linear-tubular electric motors and hydraulic actuator based systems, cost and complexity have delayed large scale deployment in serie...

Abstract Vehicle braking stability performance can improve the safety of vehicle driving during a braking. However, some parameters structure impact on stability, characteristic law relevant is ignored. A simulation model established using software CarSim. The included in system, suspension, steering mechanism, system. wheelbase, and height centre mass analysed. concluded. Based law, ideal obta...
