    Investigation on the possibility of cold nuclear fusion in Fe-Zr amorphous alloy (1989)

    Notes: Abstract Neutron, γ and Mössbauer spectroscopy were used to study the possibility of cold nuclear fusion in Fe90Zr10 amorphous ribbon having high hydrogen absorbing ability. No significant changes in the neutron and in the γ spectra were found at deuterization performed electrochemically at different cathodic potentials. The observed differences between the Mössbauer spectra of samples deuterized in air and in nitrogen atmosphere can be explained by decrease of deuterium uptake as well as by a small heat effect due to reaction of hydrogen with oxygen dissolved in water in the case of electrolysis carried out in air.

    Course of cerebral lesions in a patient with periarteritis nodosa studied by magnetic resonance imaging (1989)
    Springer

    Notes: Summary The course is reported of a patient with periarteritis nodosa who initially presented with neurological symptoms. Multiple cerebral lesions were documented by the first magnetic resonance imaging (MRI) investigation. The majority of these had disappeared completely in the follow-up MRI studies. In contrast to neurological improvement the patient eventually died due to multiorgan failure. Postmortem histological examination revealed no pathological findings in the brain except one single necrotic area already known from MRI. Remissions of histological and angiographic alterations in periarteritis nodosa have been described as “local healing” leading to fibrosis and scarring. Our findings suggest that restitutio ad integrum may occur, at least in cerebral lesions.

    Intestinal neuronal degeneration in a patient with chronic idiopathic intestinal pseudoobstruction (1989)
    Springer
    Digestive diseases and sciences 34 (1989), S. 123-128

    Notes: Summary Neuropathological examination of the gut in a patient with chronic idiopathic intestinal pseudoobstruction and temporal lobe epilepsy showed a degeneration of Auerbach's and of Meissner's plexus. The extent of degenerative changes increased in an aboral to oral direction. Neuronal degeneration was characterized by ballooning of the cytoplasm of the ganglial cells, by a hyperargyrophilia, a shortening and dilation of cell processes, and a progressive fragmentation and loss of axoris. In rectal biopsies, a PAS-positive granular material was detected in the cytoplasm of ballooned ganglial cells. A severe peripheral neuropathy with fiber degeneration in the posterior columns and axonal lesions within ventral nerve roots and a more recent fiber degeneration in the lateral columns corresponding to the picture of subacute combined degeneration of the spinal cord and a symmetrical Ammon's horn sclerosis was present. This case of progressive intestinal neuronal degeneration of unknown origin is a newly described condition leading to chronic idiopathic intestinal pseudoobstruction.
