BACKGROUND Samarium-153 particulate hydroxyapatite (Sm-153 PHYP) is a relatively new radiation synovectomy agent developed for the treatment of chronic synovitis. Although it has been shown that the levels of unwanted extra-articular radiation are lower after intra-articular injection of Sm-153 PHYP than yttrium-90 colloid, its clinical efficacy has not been rigorously studied. OBJECTIVES To ...

Even though high-dose chemotherapy followed by autologous stem cell support has proven superior to conventional treatment, relapse occurs in approximately 75% of patients within five years after autologous transplantation. Initiating salvage treatment after high-dose therapy may be a reasonnable approach with survival time from relapse being more than two years as documented recently. Reported ...

BACKGROUND Radium-223 chloride ((223)Ra; Alpharadin) is an alpha-emitting radioisotope that targets areas of osteoblastic metastasis and is excreted by the small intestine. When compared with beta-emitters (eg, strontium-89, samarium-153), (223)Ra delivers a high quantity of energy per track length with short tissue penetration. OBJECTIVE This review describes the mechanism, radiobiology, and...

Studies on insect dispersal and other behaviors can benefit from using markers that will not alter flight and fitness. Rare earth elements, such as samarium (Sm), have been used as ingested markers of some insects and detected using neutron activation analysis (NAA). In this study, samarium nitrate hexahydrate was mixed into artificial diet for boll weevils, Anthonomus grandis grandis Boheman (...
