BACKGROUND Neutron capture therapy for glioblastoma has focused mainly on the use of (10)B as neutron capture isotope. However, (157)Gd offers several advantages over boron, such as higher cross section for thermal neutrons and the possibility to perform magnetic resonance imaging during neutron irradiation, thereby combining therapy and diagnostics. We have developed different liposomal formul...
Boron neutron capture therapy (BNCT) involves administration of a boron compound followed by neutron irradiation of the target organ. The boron atom captures a neutron, which results in the release of densely ionizing helium and lithium ions that are highly damaging and usually lethal to cells within their combined track length of approximately 12 microns. Prior to Phase I clinical trials for p...
The use of heavy liquid metals, and especially of lead-bismuth eutectic (LBE) or lead for accelerator-driven systems (ADS) and lead-cooled (Pb) or lead-alloy-cooled (primarily Pb-Bi) fast reactor (FR) concepts of Generation IV requires an assessment of their compatibility with structural materials. Their deployment requires that the materials compatibility issue will be resolved, with and witho...
Most analytical techniques do not comply with the need for direct trace element analysis of samples exceeding the order of grams. Instead, sub-sampling methods are used to obtain representative sampling of the initial material. The possibilities arising from directly analyzing voluminous samples have been discussed [4]. Instrumental Neutron Activation Analysis (INAA) is a powerful technique, wh...
