Quasiclassical dynamics of proton scattering by N2 on an improved ab initio potential energy surface
(2001)
An improved analytical representation of the ground electronic potential energy surface (PES) of the (H+, N2) system is generated using the ab initio data reported in our earlier work. The new analytical PES function describes adequately the global behavior and in particular the angular dependence of the interaction as well as the long-range part so that it is amenable to scattering studies. We investigate the elastic and inelastic H+-N2 scattering dynamics on this PES by the quasiclassical trajectory method for center-of-mass collision energies in the range 29-144 eV. The trajectory results thus obtained are compared with the available experimental findings and with recent quantum-mechanical (vibrational close-coupling rotational infinite-order sudden) results. Despite some differences, the experimental data are well reproduced by the present calculations.
Dendritic cells (DCs) are the most potent antigen-presenting cells of the immune system and are currently being investigated in clinical applications as cancer vaccines. An efficient cryopreservation method would greatly contribute to their use in clinical trials. We have established a method for freezing of DCs derived from peripheral blood mononuclear cells using the plasma expander Gelifundol. This enabled us to reduce the concentration of the toxic DMSO to 5%. The method could be performed without the addition of fetal calf serum or any other serum. After freezing, the viability of the DCs was 90%. The cells exhibited all the phenotypic characteristics (CD11c+, HLA-DR+, CD80+, CD83+, CD86+) of DCs, as tested by flow cytometry. Cells transfected with cDNA for the tumour antigen mucin expressed this protein on their surfaces in the same manner as before freezing. The stimulating capacity of a mixed lymphocyte culture was also preserved. These findings offer an efficient method for the cryopreservation of DCs for use in clinical trials.
