Purpose: To recognize affective factors in delivering X-ray contrast agents (which have high atomic number) via gallium carrier to liver or lymphatic neoplasm cells.   Materials and Methods: Since uptake of gallium by liver has been reported in numerous researches, it was bonded with a contrast media (metrizoate). X-ray imaging was done to determine geometric features of liver.   Results: Rad...

background and purpose : there has been no report in which preoperative evaluation of adc for prediction of post therapeutic outcome was presented. the aim of our study was to retrospectively evaluation the use of the apparent diffusion coefficient (adc) for the prediction of malignancy and the outcome of malignant astrocytic tumors. methods: we reviewed mri of 26 male and 14 female patients wi...

background: various frequencies of sperm aneuploidy are reported in sperms of subfertile patients compared to normal individuals. moreover, sperm dna damage is shown to be associated with male infertility. in this study, the rate of dna damage and frequencies of aneuploidy in sperms of subfertile patients was investigated. methods: semen samples were obtained from healthy normal and subfertile ...

Selective protein labeling with a small molecular probe is a versatile method for elucidating protein functions in living cells. In this review, we report a new protein labeling method that enables selective covalent modification of a tag-fused protein with small functional molecules. This method utilizes the specific interaction and rapid reaction between a short peptide tag and a molecular pr...

  Introduction: Radioimmunotherapy (RIT) is a very promising new therapy for the treatment of recurrent B-Cell non-Hodgkin's lymphoma (NHL). Iodine-131 is the most frequently used nuclide in clinical RIT, but its usefulness has been limited by dehalogenation of monoclonal antibodies labeled via conventional methods. To circumvent this problem, we have synthesized a tr...
