    Description:
    Elektronisches Publizieren und online verfügbare Quellenbestände haben die Geschichtswissenschaft verändert. Gesunkene Zugangshürden und einfache Suchmöglichkeiten beschleunigen den Blick in Quellen sowie Literatur und verbreitern die empirische Basis. Programme zum Bibliographieren, Recherchieren und Exzerpieren ersetzen den Zettelkasten, strukturieren unser Wissen neu und vereinfachen den Blick über geographische und disziplinäre Grenzen hinaus. In der Geschichtswissenschaft viel weniger bekannt sind dagegen Möglichkeiten zur Untersuchung großer Textkorpora mittels computerlinguistischer Methoden. Solche Forschungen versuchen qualitative und quantitative Analyseschritte miteinander zu verbinden. Dieser Sprung von der »digitalisierten« zu einer »digitalen« Geschichtswissenschaft, die algorithmische Analyseverfahren methodisch innovativ nutzt und reflektiert, ist längst noch nicht vollzogen.

    Abstract  Superfusing Xenopus laevis oocytes with NH4Cl (10 mmol/l, pH 7.5) resulted in an inward current at a clamp potential of –70 mV. In paired experiments (n=22), the NH4Cl-induced peak current was –293±94 nA, under control conditions (osmolality: 240 mosmol/kg), and rose to –523±196 nA when osmolality was reduced to 144 mosmol/kg. In parallel with the rise in NH4Cl-induced inward current, membrane conductance at –70 mV doubled and the zero-current potential changed from +3.3±9.4 mV to –22.0±8.0 mV (n=22) in the presence of NH4Cl during exposure to a hypoosmolar solution. In the absence of NH4Cl, oocytes responded to hypoosmolality with a shift in zero-current potential to more negative values and an increased conductance which became partially sensitive to isosorbiddinitrate (ISDN), suggesting the activation of a volume-sensitive K+ channel. Membrane conductance in the presence of NH4Cl was decreased by ISDN to similar extents under isoosmolal and hypoosmolal conditions, indicating that NH4 + enters the oocytes through a volume-sensitive conductance separate from the ISDN-sensitive K+ channel.

    Abstract. The two-electrode voltage-clamp technique in combination with tracer uptake experiments was used to investigate the dependence of dicarboxylate transport kinetics on membrane potential in Xenopus laevis oocytes expressing the flounder renal high-affinity-type sodium dicarboxylate cotransporter (fNaDC-3). Steady-state succinate-dependent currents in the presence of Na+ were saturable with an apparent affinity constant for succinate, K 0.5,succ, of 60 µM. K 0.5,succ was independent of membrane potential, suggesting succinate binding at the surface of the fNaDC-3 protein. The maximal succinate-dependent current, ΔI max, increased with hyperpolarization, suggesting that the empty carrier may translocate net charge. Succinate-induced currents showed sigmoidal dependence on Na+ concentration, and K 0.5,Na+ decreased with hyperpolarization, suggesting Na+ binding in an ion well. Lowering the external Na+ concentration to 20 mM increased K 0.5,succ approximately threefold. Succinate-induced currents were inhibited by Li+ with an K i,Li+ of approximately 0.5 mM, and a Hill coefficient of below unity indicating the interaction of one Li+ ion with an inhibitory site at fNaDC-3.

    Notes:
    Abstract The goal of this study was to determine whether Na+HCO3 − cotransport from rat renal cortex can be functionally expressed in Xenopus laevis oocytes. Using a two electrode voltage-clamp device, HCO3 −-dependent currents were determined as the difference in current measured in a nominally HCO3 −-free buffer, pH 7.5 and a buffer with 30 mmol/l HCO3 −, pCO2 5.33 kPa, pH 7.5. The size of renal cortex mRNA required to express maximum HCO3 −-dependent current was 2–3 kb. The expressed current depended on Na+ and was sensitive to 4,4′-diisothiocyanostilbene-2,2′-disulfonic acid (DIDS) and acetazolamide (each 1 mmol/l), inhibitors known to block the native Na+HCO3 − cotransporter in several tissues including rat proximal tubule. Water-injected oocytes did not show any measurable response either to increased HCO3 − nor to Na+-free perfusion or to the inhibitors, indicating the absence of an endogenous electrogenic HCO3 − transporter. Our data indicate that the rat renal mRNA of 2–3 kb size contains the message for the Na+HCO3 − cotransporter.

    Abstract  Current-clamp and voltage-clamp techniques were used to study the effects of NH4 + on the cell membrane conductance in Xenopus laevis oocytes. Superfusing the oocytes with NH4Cl resulted in a depolarization of the oocyte’s cell membrane potential and, at a clamp potential of –70 mV, in an inward current. The magnitude of the inward current was proportional to the NH4Cl concentration in the extracellular solution and on membrane potential. The reversal potential, E rev , was –35.5 ± 11.6 mV under control conditions and –3.1 ± 11.0 mV (n = 19) in the presence of NH4Cl (10 mmol/l). Superfusion of the oocytes with nominally Ca2+-free solution affected the NH4Cl-evoked response only marginally. Replacement of extracellular Na+ by N-methyl-D-glucamine+ markedly reduced, but did not eliminate, the NH4Cl-sensitive current and shifted the reversal potential to more negative potentials. The NH4Cl-induced current was substantially inhibited by 0.1 mmol/l flufenamate, and was less affected by blockers of the endogenous K+ conductance, Ba2+ and isosorbiddinitrate (ISDN). The results are compatible with the activation of a conductance by NH4Cl for Na+ and NH4 +. The mechanism by which NH4Cl activates the conductance remains unknown.
