background: the induction of cancer appears to be the most important effect of low-dose ionizing radiation to occur in an exposed population. in developing countries 94% of human radiation is from natural sources. in iran some high altitude regions such as, chaharmahal & bakhtiari has high levels of the natural background radiation (higher than the worldwide average). therefore, investigation o...

introduction: c - reactive protein (crp) is an acute-phase plasma protein that can be used as a marker of activation of the immune system. in response to several inflammatory reactions,the concentration of crp increases and recently have been applicated as a cancer detector in some studies. we aimed to evaluate the relation between crp level and the staging and grading of gastric and colon mali...

a thorough recognition of the nature and duties of the genes is based upon having adequate information about the proteins. however, the proteomic projects follow a slow trend; therefore, solving the protein-related problems has become as one of the most important challenges in bio-informatics. consequently, the presence of tools which can enhance the structural recognition, classification, and ...

cancer registration is an important source for measuring the burden of cancer in a population. in practice, however, quite frequently incorrect patients are registered or data items can be inaccurately recorded or not recorded at all. also the process or quality of these registrations varies among countries. in this paper, we briefly discussed some statistical techniques including; mortality an...
