introduction relative dose computation is a necessary step in radiation treatment planning. therefore, finding an approach that is both fast and accurate seems to be necessary. the purpose of this work was to investigate the feasibility of natural cubic spline to reconstruct dose maps for linear accelerator radiation treatment fields in comparison with those of the simulation. materials and met...

background: the aim of this study was to evaluate the radioprotective capacity of some novel aminoalkylated dithiocarbamic acid potassium salts against γ-irradiation in mice. materials and methods: eight compounds containing 2-aminoethyl-, 3- aminopropyl-, 4-aminobutyl-, 5-aminopentyl-, 6- aminohexyl-, 7-aminoheptyl-, 8-aminooctyl and 9- aminononyl of dithiocarbamate derivatives were prepared. ...

Interferon gamma (IFN-γ) is one of the key cytokines in defining T helper 1 lymphocyte immuneresponses. In this study, the bovine IFN-γ gene was cloned from spleen tissue RNA using the reversetranscription-polymerase chain reaction (RT-PCR). IFN-γ cDNA was sub-cloned and expressed inmammalian expression plasmid (pcDNA3.1(+)) under the control of the human cytomegalovirus (CMV)promoter. The pred...

Na radioactively decays to an excited state of Ne either by emission of a positron (90% probability) or by electron capture (10% probability). The excited Ne nucleus decays with a mean life 3×10−12 s to the ground state with the emission of a 1.274 MeV gamma. The positrons are emitted with a range of kinetic energies up to about 0.5 MeV. They lose this energy quickly (10−9 s) in the material !"...
