backgrounds and aims: p53 gene is regarded important in pathogenesis of different cancers. therefore, this study aimed to investigate the frequency of p53 gene codon 72 arg/pro polymorphism in women suffering from breast cancer. materials and methods: a total of 90 patients with breast cancer and 83 matched healthy control women participated in this case-control study. genomic dna was extracted...

abstractbackgroundline of treatment for management of hydrocephalus despite available new techniques andsystems of shunting. associated complications should be recognized and managed properly,but the most recognized complications are shunt obstruction which its prevalencethrough surgical approach is discussed here. two approaches (frontal and parietal) are usedto insert ventriculoperitoneal shu...

To determine ventriculoperitoneal shunt patency during routine MR imaging of the head, 23 patients were studied with T1-weighted fast-field-echo scans. Without knowledge of the results of previous MR/CT studies or of the patients' clinical history, we reviewed the fast-field-echo studies and divided them according to those judged to have shunt flow (18) and those judged not to have flow (five)....

in this paper the simulation of pathological behavior in gait locomotion of central nervous system (cns) diseases and effects of rehabilitation techniques are investigated. these simulations noticeably deepen the knowledge of researches in neurorehabilitation realm about the neuroscientific basis of cns treatment after a neural disorder. however, only a limited number of these simulations have ...

The system fault behavior model was investigated by the author first. System fault behavior model describes the occurrence and development process of malfunction in product, and analyzes the transmission process of unit malfunction in system and effects of various factors on system. In order to realize simulation of system fault behavior, it is necessary to perform formalized process of system ...
