introduction:it is well-recognized that collimator-detector response (cdr) is the main image blurring factor in spect.  in this research, we compensated the images for cdr in molecular spect by using stir reconstruction framework. methods: to assess resolution recovery capability of the stir, a phantom containing five point sources along with a micro derenzo phantom were investigated. influence...

vicia sativa l., an annual winter growing leguminous plant, is a valuable source of protein and minerals for cattle. drought is one of the key stress factors that influence plant growth and development. in order to investigate common vetch physiological and molecular responses under normal irrigation (n) and two levels of drought stress [s1= 30% and s2= 10% field capacity (fc)], a greenhouse exp...

in this work quantitative structure activity relationship (qsar) methodology was applied for modeling and prediction of cellular response to polymers that have been designed for tissue engineering. after calculation and screening of molecular descriptors, linear and nonlinear models were developed by using multiple linear regressions (mlr) and artificial neural network (ann) methods. the root m...

Background: Although Imatinib has revolutionized the treatment of chronic myeloid leukemia (CML), not all patients reach complete remission and a considerable proportion of the patients develop resistance to Imatinib. Material and Methods: In an attempt to increase the tail on the survival curve, we conducted a Phase I/II study of PR1/BCR-ABL multipeptides vaccination trial in CML patients wit...

In this work, three types of natural clays including kaolinite, montmorillonite, and illite with different molecular structures, as adsorbents, are selected for the removal of methylene blue dye, and their performance is investigated. Also the optimization and the analysis of the dye adsorption mechanism are performed using the response surface methodology, molecular modeling, and experimental ...

introduction: pathophysiology of cancer is based on genetic instabilities. this can explain recent important role of genetic studies in such diseases. defects can be large (on molecular scale) at the level of chromosomal or small in nucleotide level, which eventually causes to irreversible change in the cell. conventional technical methods in cancer genetics are generally based on molecular or ...
