Depolarization-activated outward K+ currents in isolated adult rat ventricular myocytes were characterized using the whole-cell variation of the patch-clamp recording technique. During brief depolarizations to potentials positive to -40 mV, Ca(2+)-independent outward K+ currents in these cells rise to a transient peak, followed by a slower decay to an apparent plateau. The analyses completed he...

Quasi oxygen-deficient indium tin oxide nanoparticles (ITO NPs) were prepared by photoinduced chlorine doping, and exhibited much enhanced electrocatalytic activity for oxygen reduction reaction (ORR) in alkaline media, as compared with pristine ITO.

Dun, Wen, Parag Chandra, Peter Danilo, Jr., Michael R. Rosen, and Penelope A. Boyden. Chronic atrial fibrillation does not further decrease outward currents. It increases them. Am J Physiol Heart Circ Physiol 285: H1378–H1384, 2003; 10.1152/ajpheart.00137.2003.—Rapid atrial pacing causes electrical remodeling that leads to atrial fibrillation (AF). AF can further remodel atrial electrophysiolog...

This paper describes a novel approach of controlling cell-surface interactions through an electrochemical "switching" of biointerfacial properties of optically transparent microelectrodes. The indium tin oxide (ITO) microelectrodes, fabricated on glass substrates, were modified with poly(ethylene glycol) (PEG) silane to make glass and ITO regions resistant to protein and cell adhesion. Cyclic v...

In this study, indium-tin-oxide (ITO) nanoparticles were simply recovered from the thin film transistor-liquid crystal display (TFT-LCD) panel scraps by means of lift-off method. This can be done by dissolving color filter (CF) layer which is located between ITO layer and glass substrate. In this way the ITO layer was easily lifted off the glass substrate of the panel scrap without panel crushi...

The inhibition of the calcium-independent transient outward current (Ito) by the widely used blocker 4-aminopyridine (4-AP) was studied in adult Wistar rat ventricular myocytes, enzymatically isolated and voltage-clamped in the whole cell configuration using patch-clamp pipettes. 4-AP at 1 mmol/l concentration caused complete steady-state block of Ito at resting or hyperpolarized voltages. The ...

This paper describes a novel surface engineering approach that combines oxygen plasma treatment and electrochemical activation to create micropatterned cocultures on indium tin oxide (ITO) substrates. In this approach, photoresist was patterned onto an ITO substrate modified with poly(ethylene) glycol (PEG) silane. The photoresist served as a stencil during exposure of the surface to oxygen pla...

Physiol. 278: H295–H299, 2000.—Ba21 is widely used as a tool in patch-clamp studies because of its ability to block a variety of K1 channels and to pass Ca21 channels. Its potential ability to block the cardiac transient outward K1 current (Ito) has not been...
