    Posterior inferior cerebellar artery aneurysm in the fourth ventricle (1995)
    Springer
    Neuroradiology 37 (1995), S. 267-269 
    Details
    ISSN: 1432-1920
    Keywords: Key words PICA-aneurysm ; Intraventricular aneurysm
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract We report a patient with a ruptured aneurysm of the choroidal branch of the right posterior inferior cerebellar artery (PICA), lying in and causing an isolated haemorrhage in the fourth ventricle. MRI on the first day after bleeding revealed an abnormal vessel in the fourth ventricle, which was surrounded by a mass of intermediate signal on T1- and T2-weighted images. The aneurysm was clipped via partial splitting of the lower vermis and opening the inferior medullary velum. A postoperative angiogram confirmed complete obliteration of the aneurysm. With PICA aneurysms the rate of intraventricular haemorrhage is high and in most cases due to reflux of blood. If there is an isolated intraventricular haemorrhage, a peripheral PICA aneurysm, lying in or near the fourth ventricle, may be suspected.

    Microbial activity and biomass in mixture treatments of soil and biogenic municipal refuse compost (1996)
    Springer
    Biology and fertility of soils 23 (1996), S. 43-49 
    Details
    ISSN: 1432-0789
    Keywords: Nitrogen fractions ; Amino acids ; Amino sugars ; Microbial respiration ; Household waste ; Domestic garbage
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Geosciences , Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract An incubation experiment was performed to determine how the mixing of soil with municipal organic refuse compost affects C mineralization, growth of the microbial biomass, and changes in organic components, especially in the fractions of amino acids and amino sugars. Compost and soil differed in almost every parameter measured, with the organic C content of the compost representing only 10.8% of the dry weight. The fractions of K2SO4-extractable organic C and of non-hydrolyzable C were larger in the compost (1.24 and 62.9% of organic C, respectively) than in the soil (0.56 and 41.6% of organic C). These two fractions increased in proportion to the addition of compost, in contrast to amino sugar and amino acid C which were identified overproportionately in the mixture treatments, especially in the 30% compost treatment. Overproportionate increases in the microbial biomass C content and CO2 evolution rate were also measured in this treatment. The adsorption of compost colloids on the surface of regular soil silicates increased both the availability for microbial enzymes and the detectability for chemical analysis.
