Introduction: Depth-dose distribution curve of protons in the matter has a maximum is called Bragg peak. Bragg peak of a monoenergetic proton beam is too narrow. The spread out Bragg peak should be created for full coverage of the tumor. The spread out Bragg peak is obtained in the depth of the tumor with superposition of the several Bragg peaks. The aim of this study was coverage of an eye tum...
background & objectives: tumor diathesis (td) is defined as granular proteinaceous precipitates on slide surface of cytologic smears. it is found in the background of smears of invasive carcinoma but not in all cases. the aim of present study was to determine the prevalence of td in cervicovaginal smears from patients with uterine cervix carcinoma. methods: cytological smears and histologi...
today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...

the relationship between imp3 expression in colorectal adenocarcinoma and clinicopathologic findings
conclusions imp3 immunoreactivity was associated with poor differentiation of tumor yet not associated with tumor size depth of invasion or lymph node involvement. results immunoreactivity pattern of imp3 was cytoplasmic in different clinicopathologic findings. among different clinicopathologic findings, we found a statistical relationship between tumor differentiation and imp3 (p = 0.047); so ...
abstract background: gastric cancer is one of the most common cancers in the world especially in iran. there are many genomic and molecular factors that cause gastric cancer to occur. also, many markers that associate with tumor invasiveness have been known. e-cadherin is a calcium- mediated cell adhesion molecule. in some studies, abnormal expression of e-cadherin has been seen in gastric car...
background: the assessment of rbe quantity in the treatment of cancer tumors with proton beams in treatment planning systems (tps) is of high significance. given the significance of the issue and the studies conducted in the literature, this quantity is fixed and is taken as equal to 1.1. objective: the main objective of this study was to assess rbe quantity of proton beams and their variations...
in this study, scour of mashkid bridge pier located in mashkid river of saravan county has been studied and to measure the scour rate, the numerical model hec-ras 4.0 has been used. upon selection of mashkid river as the case study and whereas the studied zone is important with respect to the climatic conditions and showery monsoon raining and flowing the great and destructive floodwaters, ther...

Background: After breast conserving surgery, most recurrences occur around the primary tumor site. This justifies the use of boost radiotherapy to the primary site of tumor. Surgical scar is not always a good surrogate for the location of the lumpectomy cavity. The aim of this study was to evaluate ultrasonic guidance for detection of the lumpectomy cavity after breast conserving surgery ...
