    Notes: Summary By comparing the theoretically expected results of photon emission from a chaotic (thermal) field and those of an ordered (fully coherent) field with the actual experimental data, one finds ample indications for the hypothesis that ‘biophotons’ originate from a coherent field occurring within living tissues. A direct proof may be seen in the hyperbolic relaxation dynamics of spectral delayed luminescence under ergodic conditions. A possible mechanism has to be founded on Einstein's balance equation and, under stationary conditions, on energy conservation including a photochemical potential. It is shown that the considered equations deliver, besides the thermal equilibrium, a conditionally stable region far away from equilibrium, which can help to describe both ‘biophoton emission’ and biological regulation.

    Ordered array of dendritic cells and CD8+ lymphocytes in portal infiltrates in chronic hepatitis C (2001)

    Notes: Ordered array of dendritic cells and CD8+ lymphocytes in portal infiltrates in chronic hepatitis C Aims: Despite the importance of dendritic cells in stimulating primary and secondary immune responses by presenting antigens to T-lymphocytes in draining lymph nodes and peripheral tissues, respectively, very limited information is available on the presence and localization of these cells in hepatitis C virus (HCV)-related chronic active hepatitis. Therefore, we addressed the ultrastructure, immunophenotype, distribution and relationships to lymphatics of dendritic cells in portal infiltrates of this disease. Methods and results: Part of percutaneous diagnostic liver biopsies (Knodell’s histological assessment index: 9–13) was processed for electron microscopy and for immunohistochemical detection of immune system cell membrane antigens and of the lymphatic endothelium marker podoplanin. In portal infiltrates, cells with electron microscopical and cell marker features of dendritic cells and expressing the activation markers CD54, CD80, CD83 and CD86 were organized in a discontinuous network, that embedded CD8+ lymphocytes in close contact with dendritic cells and came in contact with hepatocytes, sometimes infiltrating beyond the limiting plate. Also, dendritic cells were found within newly formed lymphatic capillaries in thin, infiltrated septa among hepatocytes. Conclusions: This evidence strongly suggests a critical role of dendritic cells and newly formed lymphatics in the pathogenesis and organization of the immune infiltrate that characterizes HCV-related chronic active hepatitis.

    Biophoton emission fromDaphnia magna: A possible factor in the self-regulation of swarming (1991)
    Springer
    Cellular and molecular life sciences 47 (1991), S. 457-460 
    Details
    ISSN: 1420-9071
    Keywords: Swarm density ; animal distance ; body size ; photons ; self-regulation ; Daphnia magna

    Topics: Biology , Medicine
    Notes: Summary The formation of swarms by planktonic organisms was first described almost 100 years ago, but the mechanisms governing the development of patterns in population size and density are still not understood. In this study, we investigated one biophysical factor that may play an important role in swarm-formation. Spontaneous ultraweak photon emission in the visible range has been well documented for living cells, tissues and individuals in the plant and animal kingdom, including humans. We demonstrate here that the intensity of light emitted by the planktonic crustaceanDaphnia magna is a function of population density in relation to body size. The effects are discussed on the basis of the theory of Dicke1,2, and it is suggested that biophoton emission may be a basic factor in the self-regulation of swarm density.
