    Notes: Abstract Exposure of isolated guinea-pig ventricular myocytes to the uncharged oximes 2,3 butanedionemonoxine (BDM) and norPAM (but not by the charged PAM) results in a dose-dependent reduction of the duration of the action potential. The nifedipine-sensitive Ca current is fully inhibited by BDM (IC505.8±0.4 mM) and nor PAM but is little affected by PAM. This inhibition is unaltered by the presence of BAY K 8644 but is antagonized by isoprenaline. The effect of isoprenaline is more pronounced when the solution in the patch pipette contains the non-hydrolysable analogue of adenosine 5′-triphosphate, ATPγS (the IC50 is increased to 44.0±5.2 mM). A hastening of the inactivation of the L-type Ca current persists when either 10 mM 1,2-bis(2-aminophenoxy)-ethane-N, N, N′, N-tetraacetic acid (BAPTA) or 3 mM ATPγS is present in the pipette solution or when BAY K 8644 or isoprenaline are present in the bathing fluid. These results suggest that the inhibition of the Ca current is due to the phosphatase-like activity of the oximes but differs in some respects from previous work where a reduced level of phosphorylation is achieved by the introduction of protein kinase inhibitors or protein phosphatases into the sarcoplasm in guinea-pig myocytes. These differences could be explained if Ca channel availability is regulated by at least two sites of cAMP-dependent phosphorylation with oximes able to rapidly dephosphorylate both sites, while one of these sites is not readily dephosphorylated by the endogenous phosphatases.

    Notes: Abstract A method for the manufacture of ion-sensitive micro-electrodes, which can be readily used with small single cells, is described in detail. A glass pipette with a tip size of 1 μm, essentially similar to those used as suction electrodes in whole-cell recording, when silanized and with its tip filled with a suitable ion-sensitive resin, producesan ion-sensitive electrode with fast electrical and chemical response times. These electrodes can be applied to the cell membrane of isolated myocytes and penetration achieved without cell damage, by the application of suction. For the estimation of intracellular ionic activities they can be used in conjunction with a separate conventional KCl-filled micro-electrode or a suction voltage electrode. The technique is illustrated by the measurement of intracellular Na+, Ca2+ and pH. It is possible that these electrodes can also be used to measure local changes in ionic activity in restricted areas.

    Description / Table of Contents: Zusammenfassung Titan-Ferrocolumbit ist ein seltenes Akzessorium in den Spodumenpegmatiten der Weinebene, Kärnten, Österreich. Er enthält entmischten niobhaltigen Rutil und selten Einschlüsse von möglicherweise primärem Zinnstein. Die Zusammensetzung des TitanFerrocolumbits ist relativ homogen und weist die folgenden Elementverhältnisse auf. Mn/(Mn + Fe) 0,24 – 0,33, Ta/(Ta + Nb) 0,09 – 0,13 (Atomverhältnisse) und 0,47 – 0,88 Ti pro 12 Kationen (2,7 - 5,0Gew.%TiO2). Natürlich auftretende Kristalle sind strukturell merklich ungeordnet und erlangen durch Erhitzen einen höheren Ordnungsgrad. Die Mn/(Mn + Fe) sowie Ta/(Ta + Nb) Verhältnisse des niobhaltigen Rutil betragen 0,00 – 0,04 bzw. 0,26 – 0,38. Der niobhaitige Rutil ist im Vergleich zu Mn- und Nb-führendem Ferrocolumbit an Fe, Ta, Ti und Sn angereichert.—Die Seltenheit von Nb, Ta-Oxiden in den spodumenführenden Pegmatiten der südlichen Ostalpen steht in Übereinstimmung mit ihrer Zugehörigkeit zum Albit-Spodumen Typ der selten-Element-führenden Pegmatite (rare-element pegmatites).
    Notes: Summary Titanian ferrocolumbite is a rare accessory mineral in the spodumene-bearing pegmatites at Weinebene, Carinthia, Austria. It contains abundant exsolved niobian rutile and scarce inclusions of cassiterite that may be primary. The titanian ferrocolumbite is relatively homogeneous with Mn/(Mn + Fe) 0.24–0.33, Ta/(Ta + Nb) 0.09–0.13 (atomic ratios) and 0.47–0.88 Ti per 12 cations (2.7–5.0 wt.% TiO2). Natural specimens are considerably disordered but become more ordered on heating. Niobian rutile has Mn/(Mn + Fe) 0.00–0.04 and Ta/(Ta + Nb) 0.26–0.38; it concentrates Fe, Ta, Ti and Sn relative to the Mn- and Nb-enriched ferrocolumbite. The overall scarcity of Nb, Ta-oxide minerals in the spodumene-bearing pegmatites of southern Ostalpen conforms to their general features ranking them with the albite-spodumene type of rare-element pegmatites.

    Notes: Abstract Four fluvalinate formulations differed in their residual toxicity to female two-spotted spider mite (TSM), Tetranychus urticae adults; the emulsifiable concentrate (EC) was the most toxic. In contrast, there was little difference in toxicity between the formulations with the European red mite (ERM) Panonychus ulmi with the exception of the EC formulation which was the least toxic. Fluvalinate 2F caused minimal (〈10%) TSM and ERM egg mortality. Fluvalinate 2F was more toxic and caused greater larval dispersal for the TSM compared to the ERM at the field concentration and below. The toxicity of fluvalinate 2F to TSM and ERM protonymphs, deutonymphs and adults was low, approximately 〈20% at field concentration. Dispersal was the main response to fluvalinate and this was positively correlated with increasing concentration. The combined mortality and dispersal LC50 was five times lower for ERM protonymphs and adults, but 11 times higher for ERM deutonymphs compared to equivalent TSM life stages. Fluvalinate 2F reduced TSM development from the protonymph and deutonymph stages to a greater extent compared to the ERM. The mortality response to fluvalinate 2F was unaffected by host type (peach or apple) for the TSM whereas ERM mortality was higher on apple compared to peach. TSM dispersal was higher from apple compared to peach whereas ERM dispersal was similar on both host types. Oviposition by both mite species was lower on apple than peach leaves. A 1 h exposure to fluvalinate 2F reduced ERM oviposition for 12 days.
