The conduction pore of a cardiac potassium channel
Article Abstract:
Voltage-dependent potassium channels carrying currents IKS and IKn in the human heart, open during muscle contraction. IKS channels are formed through the assembly of subunit KVLQT1, having a single P loop, with minK, a protein. Scanning susceptibility analysis was used to determine whether minK sites have exposure in the IKS pore. It was found that potassium-selective pores are not restricted to P loops, with no strict P-loop geometry.

P-type electrical conduction in transparent thin films of CuA10sub2
Article Abstract:
Doped version of oxides Insub2Osub3, SnOsub2 and ZnO, n-type conductors, are often used as transparent electrodes in flat-panel displays. A method for identifying oxide materials that combine p-type conductivity with good optical transparency is described. The conductivity of the candidate material was lower than in some best n-type conducting oxides, it would be suitable for some applications.
