Introduction Based on Task Group No. 43 (TG-43U1) recommendations, water phantom is proposed as a reference phantom for the dosimetry of brachytherapy sources. The experimental determination of TG-43 parameters is usually performed in water-equivalent solid phantoms. The purpose of this study was to determine the conversion factors for equalizing solid phantoms to water. Materials and Methods T...
Regulation and maintenance of cell water volume and intracellular pH (pHi) are vital functions that are interdependent; cell volume regulation affects, and is in turn affected by, changes in pHi. Disruption of either function underlies various pathologies. To study the interaction and kinetics of these two mechanisms, we developed and validated a quantitative fluorescence imaging microscopy met...
With advances in genetic science, the dynamic structure of eukaryotic genome is considered as basis of gene expression regulation. Long-distance communication between regulatory elements and target promoters is critical and the mechanisms responsible for this connection are just starting to emerge. Chromatin insulators are key determinants of proper gene regulation and precise organization of c...
The present study is an attempt to find out processual and functional aspects of privacy regulation in a dialectical investigation. For this purpose, 180 samples are selected from among mothers of families in Mashhad, Iran using random sampling. In this study, "meaning structure" method has been applied. Samples participated in Laddering Interview. Analyses are set in Content-Goal Table. Based ...
