    Notes: Abstract High-spin states in187Au have been populated in the172Yb(19F, 4n) reaction and studied with in-beam spectroscopic techniques using the “Château de Cristal” 4π-multidetector array. A comprehensive level scheme of187Au has been established. Experimental band crossing frequencies and gains in alignment were deduced. Shape coexistence in187Au, well established at low spin, is found to survive up to spin 57/2, and manifests itself through well separated oblate and prolate structures.

    Description / Table of Contents: Metal Complexes of Biologically Important Ligands, LI. - Reactions of α-Amino Acids with Hexachlorpalladate(IV). Stabilization of 1-Pyrroline at Palladium(II)Hexachloropalladate(IV) reacts with an excess of α-amino acids under reduction of the metal to give palladium(II) chelate complexes PdL2 (1) (L = anion of L-Val, L-Leu, L-Phe, L-Glu, L-Gln, DL-indoline-2-carboxylic acid). Chloro-bridged complexes LPd(μ-Cl)2PdL (2) are obtained from [PdCl6]2- and L-Asp, L-Asn, and L-thioproline, respectively. With L-Met, L-Cys, L-LeuOMe, and L-PheOMe Pd(II) complexes 3-5 are also isolated. L-Pro is dehydrogenated and decarboxylated by [PdCl6]2- to yield the Pd(II) complex 6 with 1-pyrroline-2-carboxylate and 1-pyrroline as ligands. L-Cys-Cys and L-Ala yield Pd(IV) complexes 8, 9.
    Notes: Hexachloropalladat(IV) setzt sich mit α-Aminosäuren im Überschuß unter Reduktion des Metalls zu Palladium(II)-Chelatkomplexen PdL2 (1) um (L = Anion von L-Val, L-Leu, L-Phe, L-Glu, L-Gln, DL-Indolin-2-carbonsäure). Chloro-verbrückte Palladium(II)-Komplexe LPd(μ-Cl)2PdL (2) bilden sich bei der Umsetzung von [PdCl6]2- mit L-Asp, L-Asn, und L-Thioprolin. Auch mit L-Met, L-Cys, L-LeuOMe und L-PheOMe werden Palladium(II)-Komplexe (3-5) isoliert. L-Pro wird durch [PdCl6]2- dehydriert bzw. decarboxyliert, wobei der Palladium(II)-Komplex 6 mit 1-Pyrrolin-2-carboxylat und dem in freiem Zustand instabilen 1-Pyrrolin als Liganden erhalten wird. L-Cys-Cys und L-Ala bilden Palladium(IV)-Komplexe (8, 9).

    Notes: A number of cell-cycle-specific temperature-sensitive (ts) mutants have been isolated from animal cells, especially Syrian hamster cells. These ts mutants, like cell cycle ts mutants of yeast, can be complemented by specific genes, some of which have been molecularly cloned. We have isolated a cDNA clone that complements TK- ts13 cells, but only temporarily. This clone, called B1, differs from a previously isolated clone (Sekiguchi et al.: EMBO Journal 7: 1683-1687, 1988) that specifically complements ts13 cells. In addition, B1 also complemented temporarily three other ts mutants of the cell cycle, tsAF8, ts694, and ts550C cells. These mutants have different mutations since, in cell fusion experiments, they complement each other. Sequencing of the B1 cDNA clone revealed that it was a mutant of human ADP/ATP translocase in which some human sequences at the 5′ end have been replaced by SV40 sequences. The wild-type translocase was less effective but could still increase the survival time of cell cycle ts mutants at the restrictive temperature. Using the polymerase chain reaction, it was possible to demonstrate that the B1 plasmid is expressed in TK-ts13 cells undergoing temporary complementation.

    Notes: Cytokines are polypeptides released by activated vertebrate blood cells which have profound effects on other blood cells and which have hormone-like properties affecting other organ systems as well. In recent years a wide variety of these mediators has been isolated and characterized. Many of these molecules have subsequently been cloned and expressed in E. coli. The tremendous importance of these proteins to host immune and non-specific defense systems along with the striking similarities of their properties among different species suggested to us that cytokines may have been proteins that have been conserved through evolution. Investigations of the evolution of cytokines will help us decipher the complex cellular, humoral and molecular interactions that regulate host defenses. Studies of the invertebrates will shed light on the phylogenetic emergence of these molecules as well.
