    Notes: Abstract FTIR analysis of the gaseous products of the selective catalytic reduction of NO by isobutane over a Fe‐MFI catalyst made by solid‐state ion exchange shows, for the first time, that HCN can be a substantial product. Under dry conditions the amounts formed can exceed that of N2 for temperatures up to 280°C and NO conversions of 25% with a maximum HCN concentration of∼150 ppm formed at 315°C. However, introduction of 0.7% water causes the subsequent conversion of about one‐half the HCN to N2, probably through hydrolysis to NH3 and the NH3‐SCR reaction which is very rapid on Fe‐MFI. The steps through which HCN forms remain to be established.

    Wound currents and wound healing in the newt, Notophthalmus viridescens (1990)
    Springer
    Development genes and evolution 198 (1990), S. 355-362

    Notes: Summary Wounded amphibian skin heals initially by a migration of epithelial cells from the cut edge towards the center of the wound. The density of currents leaving wounds made in Notophthalmus viridescens skin was manipulated in order to determine whether electrical fields associated with these currents might have a significant role in promoting this cell migration during wound healing. Wounds were made with either a needle (200 μm) or a biopsy punch (500 μm). Currents leaving the wounds were measured with a vibrating probe, and the wounds fixed at various times after wounding. When the Na+-dependent currents were reduced by blocking Na+ channels with benzamil, wound healing, as revealed by scanning electron microscopy and by paraffin histology, was impaired. These results are consistent with the hypothesis that there is an electrical component to wound healing.
