[ 1 ] - Calculation of the Dose of Samarium-153-Ethylene Diamine Tetramethylene Phosphonate (153Sm-EDTMP) as a Radiopharmaceutical for Pain Relief of bone Metastasis
Introduction One of the important applications of nuclear physics in medicine is the use of radioactive elements as radiopharmaceuticals. Metastatic bone disease is the most common form of malignant bone tumors. Samarium-153-ethylene diamine tetramethylene phosphonate (153Sm-EDTMP) as a radiopharmaceutical is used for pain palliation. This radiopharmaceutical usually emits beta particles, which...
[ 2 ] - Ultrasound effects on the activity of free and immobilized urease on the magnetic nanoparticles and silica gel
In this study, the effect of low-frequency ultrasound on the structure and activity of urease enzyme has been investigated. For this purpose, the enzyme was exposed to ultrasound with 20 kHz frequency at different time intervals. The urease enzyme was immobilized on the surface of magnetic nanoparticles (Fe2O3), and activated silica gel with 89% and 66% efficiency respectively. The enzyme activ...
