    Notes: Abstract  An overview of factors affecting metalloprotein redox potentials is given, together with an assessment of the role of site-directed mutagenesis of hemoproteins in investigating this topic and a description of several theoretically challenging hemoproteins. The conclusion is reached that a quantitative and experimentally testable description of metalloprotein redox potentials is not yet available.

    Notes: [Auszug] PHYTOCHROME is a blue-green pigment that acts as a plant photoreceptor protein in the mediation of many light-activated processes including seed germination, leaf formation, circadian rhythms and flowering. Such physiological processes are often sensitive to the quality, quantity or duration of ...

    Notes: Abstract Immunostaining of synaptic terminals was studied in the hippocampus of 26 patients who had surgical resections for intractable temporal lobe epilepsy. Two monoclonal antibodies (EP10 and SP12) reactive with distinct synaptic antigens were used on paraffinembedded tissues. The results indicated qualitative reductions on synaptic terminals in CA4 and other regions where cell loss is reported. The inner molecular layer of the dentate gyrus was observed to have increased synaptic immunostaining. Synaptic terminal loss in CA4 and redistribution in the molecular layer were most frequent in cases with hippocampal sclerosis. However, both forms of synaptic pathology were also noted in most cases where the pathological findings were classified as indefinite, and in some cases associated with mass lesions of the temporal lobe. These results support the importance of neuronal loss and synaptic reorganization as possible mechanisms of illness in epilepsy. They also indicate that synaptic immunostaining may be a useful adjunct to routine neuropathological diagnostic techniques.

    Notes: Abstract Increased numbers of oligodendrocytes and remyelination are frequently observed in multiple sclerosis plaques. It is presumed the increased numbers of oligodendrocytes are due to cell division, but this has not been proven. The mitogens within the lesion which might be responsible for this are unknown. Since oligodendrocyte proliferation occurs in areas in which there is myelin breakdown, we undertook the present study to determine if myelin basic protein (MBP) or its breakdown products could induce oligodendrocyte proliferation. MBP, or MBP digested by the neutral proteinase plasmin, was added in three concentrations to the media of adult bovine oligodendrocytes in culture. Oligodendrocytes were identified by staining for galactocerebroside. Bromodeoxyuridine incorporation was used as a measure of cell division. Oligodendrocytes were found to divide only rarely in regular culture media, in the presence of MBP, plasmin, or MBP digested by plasmin. The results indicate that MBP is not a significant mitogen for the mature oligodendrocyte.

    Notes: Abstract Ferritin from clover (Trifolium subterraneum) seeds was isolated and characterized. It was shown to contain polypeptide units of 28–26.5 kDa. The apparent molecular mass of the native protein was 560 kDa. The average iron cores were 4 nm in diameter and contained 1300 iron atoms, with Fe:P = 4:1. Purified clover apoferritin was shown to be functional by means of iron uptake experiments. Plots of initial velocities of iron uptake (at pH 6.7) into clover and horse spleen apoferritins were found to have similar profiles.
