background: finding a suitable method for rapid, accurate and reliable estimation of absorbed dose has high priority in management of the radiation exposed persons. shortly after radiation exposure, apoptosis is a major detriment in proliferative tissues such as the hematopoietic system. therefore, quantification of apoptosis in these tissues could be useful for rapid estimation of radiation ex...

Background and Objective: Determining adequate model and estimation of target dose with high precision is a key goal in dose-response studies. MCPMod is a new method that used for model selection and estimation of target doses and unlike other methods it does not have any limitation.  In this method, selection of models has performed by hypothesis testing also increasing responses that are a cr...

Estimation of absorbed dose for radiation workers or person involved in different radiological accident is the aim of biodosimetry. Cytogenetic methods are the most current and applicable biodosimetry tools. In chronic or protracted exposure, fluorescence in situ hybridization (FISH), stable chromosomal aberration is used for estimation of absorbed dose. For precise estimation of absorbed dose,...

Introduction: Using artificial intelligence tools in pharmacogenomics is one of the latest bioinformatics research fields. One of the most important drugs that determining its initial therapeutic dose is difficult is the anticoagulant warfarin. Warfarin is an oral anticoagulant that, due to its narrow therapeutic window and complex interrelationships of individual factors, the selection of its ...

This study evaluated the impact of contrast material on the estimation of absorbed dose due to computed tomography pulmonary angiography (CTPA) using the ICRP reference phantoms. To address this issue, we modified the previously developed physiologically based pharmacokinetic (PBPK) model to be conformed to the ICRP reference phantoms. Regarding the standard contrast material injection protocol...
