Standards are strongly intertwined with values in economic contexts, which goes far beyond value. Standards’ diversity is expressed local spaces where standards made, put into action, circulate and commensurate. In these mutually linked globally distributed spaces, we can analyze the ways value(s) encounter each other what consequences this brings for individuals, organizations, communities, so...
introduction: spatial dose distribution around the radionuclides sources is required for optimized treatment planning in radioimmunotherapy. at present, the main source of data for cellular dosimetry is the s-values provided by mird. however, the mird s-values have been calculated based on analytical formula in which no electrons straggling is taken to account. in this study, we used geant4-dna...
A possible association between glutathione S-transferase theta 1 gene (GSTT1) polymorphism and the risk of developing prostate cancer is currently hotly debated, but evidence from various epidemiologic studies remains unclear. This investigation was performed to assess whether an association between GSTT1 polymorphism and prostate cancer risk exists by using meta-analysis to combine comparable ...
امروزه در درمان تومورهای سر و گردن درمان هدفمند با رادیونوکلئید کارسازتر است به صورتی که سلول های توموری برطرف شوند و کمترین آسیب به بافت های سالم برسد. حفظ ارگان های حیاتی در ناحیه سر و گردن در طول درمان از اهمیت بسزایی برخوردار است بنابراین باید دوز جذبی ناشی از ماده رادیواکتیو در ارگان های حیاتی محاسبه شود، عدم انجام دوزیمتری صحیح ممکن است موجب شود تا اندام های بحرانی بیشتر از حد تحمل دوز در...
Gene-set analysis of microarray data evaluates biological pathways, or gene sets, for their differential expression by a phenotype of interest. In contrast to the analysis of individual genes, gene-set analysis utilizes existing biological knowledge of genes and their pathways in assessing differential expression. This paper evaluates the biological performance of five gene-set analysis methods...
