Small-conductance (KCa2) and intermediate-conductance (KCa3.1) calcium-activated K channels are voltage-independent and share a common calcium/calmodulin-mediated gating mechanism. Existing positive gating modulators like EBIO, NS309, or SKA-31 activate both KCa2 and KCa3.1 channels with similar potency or, as in the case of CyPPA and NS13001, selectively activate KCa2.2 and KCa2.3 channels. We...

The crystal structure of the title compound, [Ni(C(6)H(6)N(4)S(2))(H(2)O)(4)][Ni(C(7)H(3)NO(4))(2)]·3H(2)O, consists of Ni(II) complex cations, Ni(II) complex anions and lattice water mol-ecules. The Ni(II) ions in both the complex cation and anion assume a distorted octa-hedral coordination geometry. O-H⋯O, N-H⋯O and C-H⋯S hydrogen bonds occur in the crystal structure.

Top-down tree transducers with "-rules ("tdtt) are a restricted version of extended top-down tree transducers. They are implemented in the framework Tiburon and ful ll some criteria desirable in a machine translation model. However, they compute a class of transformations that is not closed under composition (not even for linear and nondeleting "tdtt). A composition construction that composes "...
