objectives: the aim of this research was the development of 111in-labeled porphyrins as possible radiopharmaceuticals for the imaging of tumors. methods: ligands, 5, 10, 15, 20-tetrakis (3, 5-dihydroxyphenyl) porphyrin) (tdhpp), 5, 10, 15, 20-tetrakis (4-hydroxyphenyl) porphyrin (thpp) and 5, 10, 15, 20-tetrakis (3,4-dimethoxyphenyl) porphyrin) (tdmpp) were labeled with 111incl3 (produced from ...
A compact neutron spectrometer, based on a CH foil for the production of recoil protons and CR-39 detection, is being developed for the measurements of the DD-neutron spectrum at the NIF, OMEGA, and Z facilities. As a CR-39 detector will be used in the spectrometer, the principal sources of background are neutron-induced tracks and intrinsic tracks (defects in the CR-39). To reject the backgrou...
Background : Some studies have shown that the serum concentration of 25- hydroxy vitamin D which is represent the status of body vitamin D, has a diverse relationship with obesity status, and the risk of obesity decreases in people with high level of 25- hydroxy vitamin D. The aim of this study is to investigate the correlation between the serum level of 25- hydroxy vitamin D and anthropometric...
