introduction:holmium-166 radionuclide is one of the most effective radionuclides used for targeted therapy with theranostic properties. one method to produce this radioisotope is via the decay of its parent (indirect method). in this study applicability of extraction chromatography (exc) for separation of no carrier added 166ho from neutron-irradiated natural dysprosium target followed by quali...

Commercial cyclotron systems used for 18F production through 18O (p, n) 18F reaction face several conflicting requirements that include: reliability/uptime, quantity of consumables, safety, cost and yield. With commercialization of PET tracer distribution, higher yield has become one of the most important requirements. Maximizing yield for commercial cyclotrons require engineering trade-off amo...

A dose-limiting component of a proton accelerator-based source of epithermal neutrons is the neutron production target. Possible targets are lithium, producing high yield but having low melting point and thermal conductivity, and beryllium, presenting less engineering problems but a much smaller neutron yield. We propose that a hybrid Be-Li target would provide the best of both worlds, with the...

Multiple sclerosis (MS) is a chronic autoimmune disorder of central nervous system. This demyelinating disease affects more than 2.3 million people world wild. Most of patients are young adult. There are many possible triggering factors including infections, toxin, immunization, trauma, sunlight exposure and hormonal variable in pathogenesis of MS. One of the important trigger is stress. There ...
