    Notes: [Auszug] Fischer1 has shown that a lymphoblast, L-5178Y, that originated as a spontaneous leukaemia of thymic origin in a DBA/2 mouse can be grown in tissue culture. The cells do not stick to glass and can, therefore, be grown easily in suspension. In the medium reported by Fischer, yields of 2-3 grn. wet ...

    Notes: [Auszug] Views on the inertness of nitric oxide in the methyl nitrite system, first challenged by Carter and Travers3, had to be further revised when the methyl nitrite self-decomposition flame was discovered4 in 1955 ; this flame depends on nitric oxide reduction for its existence. Two questions arise : ...
