parameters that have to be measured in gel dosimetry. however, the resolution in gel is strongly dependant on gel composition. selection of optimum method in dose response readout and proper values of parameters can result in noise reduction as well as improvement of contrast, and spatial resolution considerably. materials and methods: magica polymer gel dosimeters were manufactured and irradia...

heteropoly acid promoted nanoparticle of nickel oxide samples were prepared by sol-gel method using heteropoly acids. prepared composite was characterized by xrd, ft-ir and icp technique. in this work, we have reported bromination of phenol, its derivatives and some aromatic compounds. the liquid phase bromination of phenol was performed using heteropoly acids immobilized nanoparticle of nickel...

abstractvarious nanoparticles have been investigated as novel drug delivery systems, including solid lipid nanoparticles (slns). due to their rapid clearance from systemic circulation, nanoparticles do not provide sustained action in most cases. different strategies have been employed to overcome this problem. in this direction, the present study introduces erodible in-situ forming gel systems ...

preparation and characterization of thermoresponsive in-situ forming poloxamer hydrogel for controlled release of nile red-loaded solid lipid nanoparticles. nanoparticles (nps) are cleared rapidly from systemic circulation and do not provide sustained action in most cases. to solve this problem, this investigation introduces an erodible in-situ forming gel system as potential vehicles for prolo...

Este trabalho consistiu na preparação e caracterização de microesferas quitosana (MQUI), quitosana/gelatina (MQUI/GEL), carregadas com cromo (MQUI-Cr MQUI/GEL-Cr) magnésio (MQUI-Mg MQUI-GEL-Mg). As foram preparadas pelo método emulsão reticulada utilizando o glutaraldeído como agente reticulação. O grau desacetilação (GD) da determinado por titulação potenciométrica foi 78,7%. espectro região d...

INTRODUCTION Children with steroid resistant nephrotic syndrome usually require treatment with second-line agents and calcineurin inhibitors such as cyclosporine are now recommended as initial therapy. These agents only recently become available in our environment and their impact on care is unknown. We reviewed the short-term treatment outcomes of their use in comparison with previous outcomes...
