this work reports a facile sonochemical route in the synthesis of nano particle of deferasirox for the first time. one application of nanotechnology is in improvement of available treatments for various diseases. deferasirox (icl670 or exjade) is a tridentate chelating agent for removing transfusion overload iron in thalassemia patients. in the present work, deferasirox was prepared in nano size...

In this study, ultrasonic-assisted matrix solid-phase dispersion (UA-MSPD) as a new sample preparation method for natural product analysis was developed. Influential parameters of the UA-MSPD method was optimized using oleuropein content of olive leaves as a model analyte. Main parameters of the proposed technique such as ultrasonic time, amplitude and pulse, sorbent material, the ratio of samp...

Background and Objectives: Flat breads are the most consumed bread in Iran. Barbari one of the popular ones, is traditional flat leavened Iranian bread and one of the most popular breads consumed in Iran and some other countries in the Middle East. Materials and Methods: The aim of this study was to evaluate the effect of substitution of wheat flour by whole quinoa flour (0-15% substitution) a...

Bioluminescence tomography (BLT) is a rapidly developing new area of molecular imaging. The goal of BLT is to produce a quantitative reconstruction of a bioluminescent source distribution within a living mouse from bioluminescent signals measured on the body surface of the mouse. While in most BLT studies so far the optical parameters of the key anatomical regions are assumed known from the lit...

Presently, the characterization of metal materials is becoming increasingly important due to the development of new materials, which is often performed numerically. Therefore, the accuracy of software simulation totally depends on the quality of the constitutive models and of their parameters. Hence, in this work, it is performed a loading path which allows to attain the most unique and disting...

Some structural control systems have been devised to protect structures against earthquakes, which the tuned mass damper (TMD) being one of the earliest. The effect of a tuned mass damper depends on its properties, such as mass, damping coefficient, and stiffness. The parameters of tuned mass dampers need to be tuned based on the main system and applied load. In most of the papers, the paramete...

A novel biosensor based on carbon nanofibers/diamine oxidase was prepared by modification of screen-printing electrodes. The enzyme diamine oxidase was immobilized onto the carbon nanofibers modified carbon screen-printed electrodes by drop and dry method followed by cross-linking reaction with glutaraldehyde. The presence of norepinephrine in analyzed samples was correlated to increasing of ca...

It is most important to assure 4 π−geometry in liquid scintillation counting for accurate results1. Usually this can be assured by dissolution of the sample in an appropriate cocktail. The cocktail does not only contain a solvent but also at least one scintillator and surfactants for aqueous samples because aqueous samples are completely insoluble in the pure organic solvents and scintillators....
