Glycine, when injected intravitreally, has an inhibitory action on the electroretinogram (ERG) of the rabbit resulting in a transient loss of the oscillatory potentials of the b-wave. This inhibitory action is reversible within 24 h after glycine injection. In autoradiographs, after [3H] glycine administration, the radioactive label is mainly found over the(More)
Posterior eye cups of the frog Rana ridibunda were prefixed in the presence of tannic acid, osmicated and stained en bloc with uranyl acetate. Electron microscopy revealed the following features of membrane traffic in cells of the retinal pigment epithelium (RPE): (1) intracellular membranes with increased electron density undergo degradation within(More)
The crystal structures of (SP-4-4)-[rac-2-(1-aminoethyl)phenyl-kappa(2)C(1),N]chlorido(pyridine-kappaN)palladium(II), [Pd(C(8)H(10)N)Cl(C(5)H(5)N)], (I), (SP-4-4)-[rac-2-(1-aminoethyl)phenyl-kappa(2)C(1),N]bromido(pyridine-kappaN)palladium(II), [PdBr(C(8)H(10)N)(C(5)H(5)N)], (II),(More)
The protonation of the phosphinito-bridged Pt(I) complex [(PHCy(2))Pt(μ-PCy(2)){κ(2)P,O-μ-P(O)Cy(2)}Pt(PHCy(2))](Pt-Pt) (1) by aqueous HBF(4) or hydrofluoric acid leads selectively to the hydrido-bridged solvento species syn-[(PHCy(2))(H(2)O)Pt(μ-PCy(2))(μ-H)Pt(PHCy(2)){κP-P(OH)Cy(2)}](Y)(2)(Pt-Pt) ([2-H(2)O]Y(2)) {Y = BF(4), F(HF)(n)} when an excess of(More)
Reactions of manganese(II) chloride, bromide and iodide with proline as an enantiopure and racemic ligand result in six crystalline solids for which diffraction experiments have been performed at 100 K. For two of these compounds, crystal structures at ambient temperature had been reported previously. The most surprising outcome of our systematic comparison(More)
The title complexes, [Pd(2)(C(8)H(10)N)(2)(C(2)H(3)O(2))(2)], (I), [Pd(2)(C(8)H(10)N)(2)Cl(2)], (II), and [Pd(C(8)H(10)N)Cl(C(5)H(5)N)], (III), respectively, have been prepared as intermediates and the final product of a cyclopalladation reaction sequence, and their structures studied by single-crystal X-ray diffraction. Complexes (I) and (II) represent the(More)
The asymmetric unit of the title compound, [CdCl(2)(C(8)H(6)N(2)O)(2)](n), consists of one mol-ecule of the 3H-quinazolin-4-one ligand, one Cd(2+) cation, which is located on a twofold axis, and one chlorido ligand in a general position. The latter bridges metal cations, forming a one-dimensional polymer along the b axis. The Cd⋯Cd distance along the chain(More)
