    Nucleation process of stacking fault tetrahedra in gold studied by positron lifetime spectroscopy (1985)
    Springer
    Applied physics 37 (1985), S. 65-72

    ISSN: 1432-0630

    Notes: Abstract By component analyses of positron lifetime spectra in quenched gold, it was found that positrons are strongly trapped by stacking fault tetrahedra (SFT) at which the lifetime is about 160 ps remarkably smaller than that for monovacancies (∼200 ps) or divacancies (∼220 ps). Positron lifetimes at small vacancy clusters were also estimated in relation to the nucleation process of SFT, with the aid of computer simulation of kinetics of vacancy clustering during quenching and on subsequent isochronal annealing. The results show that large atomic relaxation occurs in small vacancy clusters among which pentavacancies have the largest open-space, thereby having the lifetime of about 230 ps larger than that of trior tetra-vacancies (∼160ps). It is also suggested that tetra- and penta-vacancies act as prenuclei for stable nuclei of SFT consisting of six or more vacancies.

    Anti-apoptotic actions of cycloheximide: blockade of programmed cell death or induction of programmed cell life? (1997)

    Notes: Abstract Cycloheximide (CHX), long recognized for its ability to inhibit protein synthesis, has been widely employed in studies of cell death to the extent that prevention of cell death by CHX has been used as prima facie evidence for a subtype of apoptosis called ‘programmed cell death’. However, very rarely have investigators determined the effects of CHX on protein synthesis in their particular cell death paradigms. Recent findings are revealing alternative mechanisms of action of CHX that involve, ironically, stimulation of cytoprotective signalling pathways. For example, in embryonic rat hippocampal cell cultures CHX protects neurons against oxidative insults by a mechanism involving induction of neuroprotective gene products including Bcl-2. CHX induces increases in immediate early gene mRNA levels, and can activate several different kinases and transcription factors that are also activated by various insults and in response to anti-apoptotic growth factors. Concentrations of CHX that cause only a modest and/or transient decrease in over-all protein synthesis may prevent cell death by inducing cytoprotective signalling pathways (‘programmed cell life’), whereas higher concentrations of CHX may prevent cell death by blocking the expression of ‘death genes’. Establishing which of these anti-apoptotic mechanisms of action of CHX is operative in each cell death paradigm is clearly essential for proper interpretation of experimental results.

    Methanogenic granular sludge formation in an upflow anaerobic sludge blanket reactir treating synthetic methanolic waste (1995)
    Springer

    Notes: Abstract A laboratory upflow anaerobic sludge blanket reactor, seeded with fine, suspended, bacterial floc with 1.76 g volatile suspended solids/l, was used to treat synthetic methanolic waste. After 180 days of continuous peration, granular sludge with discrete granules of 1 to 2 mm diam. was formed, with 52 g volatile suspended solids/l. Granules were brown, relatively soft and had a settling velocity of 1.61 cm/s. Extracellular polymeric matter extracted from the granular sludge had high carbohydrate content but low nucleic acid content. The ash of the granular sludge contained Na+, K+ and Mg2+ up to 15.0, 11.7 and 3.75 mg/g, respectively. Scanning and transmission electron microscopy revealed that the granular sludge was dominated by methanogens resembling Methanosarcina.
