equitable distribution of health system resources has been a serious challenge for long ago among the health policy makers. conducted studies have mostly ever had emphasis on equality rather than equity. in this paper we have attempted to examine both equality and equity in resources distribution.this is an applied and descriptive study in which we plotted lorenz and concentration curves to des...

the acute ecotoxicity of a set of mixture samples (washing powders, wastes, fuel extracts etc.) was assessed using four acute ecotoxicity assays with aquatic organisms (daphnia magna, poecilia reticulata, artemia salina and desmodesmus subspicatus). the experimental concentration-response curves were fitted by seven two-parameter sigmoid equations using non-linear regression. the regression per...

background: magnetite (fe3o4) nanoparticles are currently one of the important and acceptable magnetic nanoparticles for biomedical applications. to use magnetite nanoparticles for bacteria cell separation, the surface of nanoparticles would be modified for immobilizing of nanoparticles on the surface of bacteria. functionalization of magnetite nanoparticles is performed by different surfactant...

this paper has two objectives. first, it establishes a model for scoring the access to pharmaceutical services. second, it develops a model for measuring socioeconomic indicators independent of the time and place of study. these two measures are used for measuring equity in access to pharmaceutical services using concentration curve. we prepared an open-ended questionnaire and distributed it to...

Concentration-response curves (CRCs) are characterized by a midpoint (EC50) and high-concentration asymptote (POmax) that relate to the agonist's affinity efficacy. Recently, third agonist attribute, efficiency, was defined as fraction of ligand binding energy is applied conformational change activates receptor. We show efficiency can be calculated from EC50 POmax estimate its value for 17 agon...

background: the purpose of this study was to characterize the pharmacokinetic parameters of mycophenolic acid (mpa) in iranian kidney transplant patients. methods: plasma mpa concentration of mycophenolate mofetile (mmf) 1 gram two times a day was measured in 21 iranian kidney transplant recipients receiving treatment. patients who entered the study had been transplanted for more than 3 months ...
