Introduction: The choice of optimal radionuclides for radioimmunotherapy depends on several factors, especially the radionuclide and antibody. The dosimetric characteristics of a non-internalizing and an internalizing monoclonal antibody (MAb) labeled with beta emitting radionuclides were investigated. Methods: Using Geant4-DNA Monte Carlo simulation, we ...

Angiosperm mesofossils are described from the Lower Cretaceous Almargem Formation exposed near village of Catefica, Portugal, and thought to be Aptian-early Albian age. The mesofossil assemblage Catefica is diverse and, in addition angiosperms here, also contains a rich non-angiosperm fossils, including leafy axes bryophytes lycopsids, lycopsid salvinialean megaspores, sporangia, sori leaf frag...

amaryllidaceae is a well-known family for its high alkaloidal content. these alkaloids comprise a unique group of bases that have been found to occur in this family. the amaryllidaceae alkaloids represent a large and still expanding group of isoquinoline alkaloids, the majority of which are not known to occur in any other family of plants this article reports on the phytochemical investigation ...

It has been shown that nitric oxide is synthesized in the central nervous system as well as in vascular endothelial cells. Recently, it was reported that nitric oxide was involved in central cardiovascular regulation, baroreflex modulation, and involved in a reciprocal release with excitatory amino acids in the nucleus tractus solitarii of rats. The purpose of the present study was to investiga...
