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...
Some of nucleoside antibiotics include complex structures as well as sensitive functionality, which are challenging targets for organic chemists. Among complex nucleoside antibiotics, there are also good drug candidates because they possess a variety of interesting biological properties. Herbicidin B and fully protected tunicaminyluracil, which were undecose nucleoside antibiotics, were synthes...
In this work, samarium ion (Sm3+) substituted yttrium iron garnet nanoparticles Y3-xSmxFe5O12 (x=0.0, 0.2, 0.3) were fabricated by the sol-gel method. X-ray diffraction (XRD) patterns confirmed the pure garnet structure for all samples. The garnet phase were studied, using, Far-FTIR. The results of vibrating sample magnetometer (VSM) represents that saturation magnetization decrease with increa...
Experimental and theoretical evidence shows that phthalimides are highly efficient single electron transfer acceptors in reactions promoted by samarium diiodide, affording ketyl radical anion intermediates, which participate in high-yielding inter- and intramolecular reductive coupling processes with different radicophiles including imides, oxime ethers, nitrones, and Michael acceptors.
PURPOSE Cancer pain is the most serious symptom for patients, especially during their terminal phase, when palliative medicine is needed. Our study tried to verify the usefulness of single-shot intravenous administration of Samarium (Sm)-153EDTMP in patients with bone metastases (group-A, N=53, males=25, females=28, age range: 30-69 years), as well as to compare a series of variables, using as ...
