    Notes: Abstract Both cellular proliferation and apoptosis (programmed cell death) have been claimed to be modulated, perhaps even triggered by, changes in intracellular pH. In this review, we summarize the evidence that gave rise to these hypotheses. To facilitate a critical appraisal of the existing data, we briefly review the main pathways involved in cytosolic pH homeostasis and their regulation by mitogens and by apoptosis-inducing agents. The information available at present suggests that cytosolic pH plays a permissive role in cellular growth and proliferation, but is neither a trigger nor an essential step in the mitogenic signal transduction cascade. Concerning apoptosis, it is clear that lowering the pH in vitro can activate DNase II. However, the evidence linking cytosolic acidification with DNA degradation in vivois presently not convincing. We conclude that the cytosolic pH, an essential physiological parameter that is tightly controlled by multiple, complementary, or redundant systems, is unlikely to play a role in signalling either cell growth or death.

    Description / Table of Contents: On the Chemistry of Kanemite [NaHSi2O5 · 3 H2O]xStarting from δ-Na2Si2O5 Kanemit was prepared by a direct exchange of Na+ by H+ in water containing reaction mixtures. By 29Si-, 23Na- and 1H-MAS-NMR investigations Kanemit was characterized as a layersilicate [NaHSi2O5 · 3 H2O]. By thermal treatment as well as by dehydration at room temperature under vacuum conditions a monohydrate is formed in which the layerstructure remains nearly unchanged. At temperatures between 100 and 110°C under normal conditions a hydrate phase of the composition [NaHSi2O5 · 0.25 H2O]x is prepared in which a changed silicate-layerstructure exists.
    Notes: Kanemit wurde aus δ-Na2Si2O5 durch einen direkten Austausch von Na+ gegen H+ in wasserhaltigem Reaktionsmedium hergestellt. Mit Hilfe von 29Si-, 23Na- und 1H-MAS-NMR-Untersuchungen wurde nachgewiesen, daß der Kanemit ein Schichtsilicat der Zusammensetzung [NaHSi2O5 · 3 H2O]x ist. Bei der thermischen, wie auch bei der Entwässerung im Vakuum bei Raumtemperatur entsteht ein Monohydrat, in dem die Schichtstruktur weitgehend erhalten bleibt. Bei Temperaturen zwischen 100 und 110°C läßt sich auch eine Hydratphase der Zusammensetzung [NaHSi2O5 · 0,25 H2O]x nachweisen, in der aber eine veränderte Schichtsilicatstruktur vorliegt.

    Notes: Abstract Wet-only rainwater composition on a weekly basis was determined at four sites in West Java, Indonesia, from June 1991 to June 1992. Three sites were near the extreme western end of Java, surrounding a coal-fired power station at Suralaya. The fourth site was ∼100 km to the east in the Indonesian capital, Jakarta. Over the 12 months study period wet deposition of sulfate at the three western sites varied between 32–46 meq m−2 while nitrate varied between 10–14 meq m−2. Wet deposition at the Jakarta site was systematically higher, at 56 meq m−2 for sulfate and 20 meq m−2 for nitrate. Since sulfate and nitrate wet deposition fluxes in the nearby and relatively unpopulated regions of tropical Australia are both only ∼5 meq m−2 anthropogenic emissions of S and N apparently cause significant atmospheric acidification in Java. It is possible that total acid deposition fluxes (of S and N) in parts of Java are comparable with those responsible for environmental degradation in acid-sensitive parts of Europe and North America.

    Notes: Abstract The occurrence of the alkaloidsN-formyl andN-acetyl loline, peramine, lolitrem B, and ergovaline and the response of aphids to plants containing these compounds were determined in species and cultivars ofFestuca,Lolium, and other grass genera infected with fungal endophytes (Acremonium spp., andEpichloe typhina). Twenty-nine of 34 host-fungus associations produced one or more of the alkaloids, most frequently peramine or ergovaline. Three alkaloids (lolines, peramine, and ergovaline) were found in tall fescue and in perennial ryegrass infected withA. coenophialum, while peramine, lolitrem B, and ergovaline were present in perennial ryegrass and in tall fescue infected withA. lolii and inF. longifolia infected withE. typhina. WhileA. coenophialum andA. lolii produced similar patterns of alkaloids regardless of the species or cultivar of grass they infected, isolates ofE. typhina produced either no alkaloids or only one or two different alkaloids in the grasses tested. Aphid bioassays indicated thatRhopalosiphum padi andSchizaphis graminum did not survive on grasses containing loline alkaloids and thatS. graminum did not survive on peramine-containing grasses. Ergovaline-containing grasses did not affect either aphid.

    Notes: We previously reported the use of polymeric delivery systems capable of sustained release of substances with molecular weights up to 2 × 106. The current study examined the tissue compatibilities of these slow-release agents and of other polymeric materials. To observe in vivo host responses to specific implants, tests were conducted in the rabbit cornea. The cornea as an implant site has several advantages compared to other organs including its clarity, avascularity, sensitivity, and convenient access to view. Corneas were examined using stereomicroscopy and histology. Two polymers suitable for sustained macromolecular release, poly(hydroxyethyl methacrylate), and alcohol-washed ethylene-vinyl acetate copolymer, were noninflammatory. Other polymers considered for sustained macromolecular release, such as polyacrylamide and poly(vinyl pyrrolidone), produced significant inflammation.

    Notes: Bafilomycin A1, a specific inhibitor of H+-ATPases of the vacuolar type, was in the present study shown, at similar concentrations, to induce secretion of lysosomal enzyme and to elevate lysosomal pH in mouse macrophages. These results lend support to the previous suggestion of a triggering role for an increase in lysosomal pH and a permissive role for cytosolic pH in the exocytosis of macrophage lysosomal enzyme. Vacuolar H+-ATPases are present in the macrophage plasma membrane as well as in intracellular membranes, for example, those of the lysosomal and phagosomal compartments. Phagosomal acidification was shown to be achieved in part by a mechanism with a similar sensitivity to bafilomycin A1 as lysosomal H+ transport and in part by an early, bafilomycin A1-insensitive mechanism. We found a lesser sensitivity towards bafilomycin A1 of the lysosomal and phagosomal H+-ATPase than that localized in the plasma membrane, indicating differences among H+-ATPases at the subcellular level. Also, by attempts to mobilize lysosomal H+-ATPase to the plasma membrane, support was obtained for the notion that subcellular H+-ATPase populations differ and thus possibly could be differentially regulated. © 1995 Wiley-Liss, Inc.

    Notes: We report first measurements of the magnetization reversal of monodisperse 30 nm and 50 nm ferromagnetic Fe3O4 particles. These particles are produced in a carrier gas as an aerosol by spray pyrolysis. After production and size selection, they are precipitated on a silicon chip with a niobium SQUID (superconducting quantum interference device) incorporated on its surface. By changing a magnetic field in the plane of the SQUID, we can measure the magnetization reversal of the particles by the flux they induce into the SQUID. The angular dependence of this reversal is determined by rotating the magnetic field around the SQUID. Scanning electron microscope (SEM) images have confirmed the particle size and revealed the position of the collected particles. If the particle concentration is too high, we cannot detect changes in the magnetic moment of a single particle, but measure the magnetic properties of the whole assembly. If only a few particles are found on the SQUID loop the angular dependence of the magnetic reversal of a single particle can be measured; this result is compared with a simple model of magnetization reversal. © 1998 John Wiley & Sons, Ltd.
