    Notes: Abstract The possibility that apoptosis and/or cell proliferation have a role in tumour progression in a murine T cell lymphoma was tested. The model consisted of the comparison of primary (PT) and metastatic tumour (MT) cells. The PT cells, but not the MT cells displayed a very pronounced tendency for spontaneous apoptosis. Proliferative capacity of MT cells was lower than that of PT cells, suggesting that it does not contribute to the metastatic phenotype in this system. Release from apoptosis does however, probably, play a role in the aggressiveness of the lymphoma.

    Notes: Abstract Theoretical mechanisms showing how antineutrons can enter a region of confined hydrogen or deuterium and decay into antiprotons is given. An annihilation reaction of a proton and antiproton releases energy. This starts a series of deuterium fissions that increase the probability of annihilation reactions. The gamma rays produced lose momentum via radiation pressure vibrations of the surrounding confinement lattice. This constitutes a change of radiation energy to kinetic energy, exhibited as heating of the lattice material. A likely mechanism of mass changing to energy is the annihilation of large particles breaking into a multiplicity of repeated less energetic positron annihilations. The explanation given shows that it is possible in theory to utilize the tremendous energy available from annihilation reactions. The harnessing of this final frontier of energy and power could ultimately prove to be the most useful energy source, particularly for propulsion systems. The reaction cited may be the initial step in using the energy from annihilation reactions. Excess heat from a Pons — Fleischmann-type reaction can be accounted for as annihilation, not fusion.
