    Ergosterol and microbial biomass relationship in soil (1996)
    Springer
    Biology and fertility of soils 22 (1996), S. 299-304 
    Details
    ISSN: 1432-0789
    Keywords: Microbial biomass ; Fungal biomass ; Ergosterol ; Fumigation extraction
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Geosciences , Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract Ergosterol and microbial biomass C were measured in 26 arable, 16 grassland and 30 forest soils. The ergosterol content ranged from 0.75 to 12.94 μg g-1 soil. The geometric mean ergosterol content of grassland and forest soils was around 5.5 μg g-1, that of the arable soils 2.14 μg g-1. The ergosterol was significantly correlated with biomass C in the entire group of soils, but not in the subgroups of grassland and forest soils. The geometric mean of the ergosterol: microbial biomass C ratio was 6.0 mg g-1, increasing in the order grassland (5.1), arable land (5.4) and woodland (7.2). The ergosterol:microbial biomass C ratio had a strong negative relationship with the decreasing cation exchange capacity and soil pH, indicating that the fungal part of the total microbial biomass in soils increased when the buffer capacity decreased. The average ergosterol concentration calculated from literature data was 5.1 mg g-1 fungal dry weight. Assuming that fungi contain 46% C, the conversion factor from micrograms ergosterol to micrograms fungal biomass C is 90. For soil samples, neither saponification of the extract nor the more effective direct saponification during extraction seems to be really necessary.

    Notes: Abstract The cadmium vacancy (VCd) and the tellurium vacancy (VTe) in CdTe are identified by Electron Paramagnetic Resonance (EPR). The EPR spectrum of the singly ionised VTe reveals cubic (unpertubed) symmetry and the hyperfine structure shows that the unpaired electron is equally spread over the four Cd neighbors. Further figand hyperfine interactions with the more distant neighbors are resolved by Electron Nuclear Double Resonance (ENDOR). The VCd is a double acceptor and the EPR spectrum is observed in its singly negative charge state. The symmerty is found to be trigonal, which can be explained in a model in which the hole occupies a dangling bondt 2 orbital and the orbital degeneracy is removed by a static Jahn-Teller distortion. The hyperfine interaction shows that the hole is localised on one of the four Te neighbors.

The VCd is a double acceptor and the EPR spectrum is observed in its singly negative charge state. The symmerty is found to be trigonal, which can be explained in a model in which the hole occupies a dangling bond t 2 orbital and the orbital degeneracy is removed by a static Jahn–Teller distortion. The hyperfine interaction shows that the hole is localised on one of the four Te neighbors.

    Cell-Free translation of Balbiani ring RNA (75S) ofChironomus tentans salivary glands into high molecular weight products (1983)
    Springer
    Development genes and evolution 192 (1983), S. 200-203 
    Details
    ISSN: 1432-041X
    Keywords: Balbiani ring ; Cell-free translation ; Chironomus messenger RNA ; Secretory proteins
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Cell-free translation of salivary gland RNA or of purified Balbiani ring RNA (75S) in a reticulocyte lysate system gives rise to high molecular weight translational products (HMTP). In addition to a common size (approx. 1×106 daltons) HMTP share imunogenic determinants with the giant secretory proteins of salivary glands. This suggests that HMTP correspond to in vivo secreted proteins and thus, corroborates the notion that 75S-RNA is the messenger for these proteins. The time course of HMTP synthesis and the lack of appearance of lower molecular weight components as translational products of 75S-RNA indicate that the synthesis of HMTP (and of secretory proteins) occurs in one piece by an uninterrupted process. HMTP are regarded the largest polypeptides so far synthesized in a cell-free system.

    Notes: Summary Substitutional Co2+ and Mn2+ ions at the two different Cd sites in the compound CsCdCl3 have been studied by using electron paramagnetic resonance. The preferential occupation, Co2+ in the CdII site, Mn2+ in the CdI site, is discussed in terms of crystallochemical symmetry arguments.

    Redetermination of the transformation enthalpies of the xanthoconite–proustite, pyrostilpnite–pyrargyrite and trechmannite–smithite phase transitions (1997)

    ISSN: 1432-2021
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Geosciences , Physics
    Notes: Abstract  We report here refined values of the transformation enthalpy for xanthoconite to proustite (54.81 kJ/mol) and pyrostilpnite to pyrargyrite (40.32 kJ/mol). Additionally, the enthalpy for the transformation of trechmannite to smithite (5.82 kJ/mol) has been determined. The refinement was possible by taking into account a previously unknown dependence of electrochemical signals on the amount of substance undergoing the reduction process.

    Pharmacokinetic aspects of the interaction between clobazam and cimetidine (1983)
    Springer
    European journal of clinical pharmacology 25 (1983), S. 139-142 
    Details
    ISSN: 1432-1041
    Keywords: clobazam ; cimetidine ; N-desmethylclobazam ; kinetic interaction ; man

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary The pharmacokinetic interaction between clobazam and cimetidine was studied in 9 healthy male volunteers in an open-labelled study. After a single oral dose of clobazam 30 mg, a wash-out period of 14 days was followed by daily doses of cimetidine 1 g for one week. Thereafter a single oral dose of clobazam 30 mg was again given. The plasma concentrations of clobazam and its main metabolite N-desmethyl-clobazam were measured by gas-chromatography. The area under the curve (AUC0−∞) of plasma clobazam level was significantly larger after pretreatment with cimetidine and the elimination half life of clobazam was significantly longer. There were no statistically significant differences in Cmax and tmax for plasma clobazam. The plasma levels of N-desmethyl-clobazam did not show any significant change after the intake of cimetidine.
