introduction: developing new radiosynovectomy agents is of great importance due to the aging of human populations around the world and increasing the incidence of inflammatory diseases. in this work, sm-153 chitosan agent was developed for the first time in our country and preparation and quality control of the compound is described. methods: sm-153 chloride was obtained by thermal neutron flu...

Rheumatoid arthritis can manifest itself through synovitis, of which the knee is the common locale. The treatment using an intra-articular radioisotope injection has been applied in various countries. In this work, the dose of radioactive material absorbed in the joint is evaluated, taking into consideration the dose received in the articular cartilage and adjacencies using a three-dimensional ...

In 2004, docetaxel was approved for the treatment of metastatic castration-resistant prostate cancer (mCRPC). For the next several years, there was a lull in drug approvals. However, from 2010 onwards, 5 additional therapies have been approved on the basis of showing a survival benefit in phase III studies. These agents include sipuleucel-T, cabazitaxel, abiraterone, enzalutamide and (most rece...

OBJECTIVE This study was designed to evaluate vascular morphological and morphometric changes induced by brachytherapy with samarium-153 (Sm-153) at high doses in hypercholesterolemic rabbits. METHODS Forty-three New Zealand White hypercholesterolemic rabbits were analyzed, and the total of 86 iliac arteries underwent balloon angioplasty injury. The rabbits were divided into three different g...

New samarium carbene complexes have been synthesized and characterized by X-ray diffraction analysis; the carbenic nature was assessed by reactivity studies.

Most cases of advanced carcinoma of the prostate are hormonosensitive. The use of combined androgen blockade (CAB) seems to improve survival and quality of life, but only when combined with chemical castration by luteinizing-hormone-releasing hormone analog and without the use of steroidal antiandrogens. After CAB, further hormonal treatments remain efficacious, such as antiandrogen withdrawal ...

Experiments on co-doped CsI:Tl,Sm suggest that samarium electron traps scavenge electrons from thallium traps and that electrons subsequently released by samarium recombine non-radiatively with trapped holes, thus suppressing afterglow. These experiments support the inference that electrons tunnel freely between samarium ions and are trapped preferentially as substitutional Sm near VKA(Tl) cent...
