introduction: the purpose of this work was to study the ability of mri normoxic polymer gel dosimetry for evaluating the dose distribution in hdr brachytherapy of esophagial cancer at imam reza brachytherapy center (mashhad, iran). materials and methods: initially, 2liters of normoxic gel (magic) was fabricated and then poured into 12 calibration test tubes and placed in a perspex walled phanto...

The development of scintillating materials is believed to reach a new step by controlling their preparation on a nanometric level. Sol-Gel chemistry offers very unique tools for nanoscale mastering of the materials preparation. In particular, shaping of the materials as thin films or nanoparticles offers new application in medical imaging. The control of doping ions dispersion thanks to soft ch...

Nano Bioactive glass material of the type CaO–P2O5–SiO2 was obtained by the sol-gel processing method at considerably lower temperatures than required for conventional melting methods. As a new modification, volume of solution was changed in order to investigate its effects on the properties of bioglass samples. The obtained material was characterized by X-ray powder diffraction (XRD), surface ...

One of the most important tasks performed in proteomics is correct analysis and interpretation of 2D electrophoresis gel images. The nonlinearities in the gel formation and image acquisition process leads to distortions, overlapped protein spots, saturated spots, faint spots, nonlinear intensity and uneven background in the gel images. As a result, pre-processing and post processing steps are v...

aloe vera is a plant of the liliaceae family with a brilliant history in disease treatment. in addition to the pharmaceutical, cosmetic, and health care industries, this plant is used in food industry due to having various nutrients such as amino acids and various vitamins or anti-bacterial compounds. the purpose of this study was to investigate the effects of variables such as temperature, tim...

Integrated opto-chemical sensors present great advantages in comparison to the current lab equipment. They bring portability, reduced costs, facilitate in-situ measurements, as well largely sample volumes. In this quest, standard processing protocols over established materials, such silicon nitride, silicon, dioxide, titanium oxide, and even a wide variety of polymers have so far been key towar...
