    OVARIAN DEFECT IN RATS CARRYING THE GROWTH AND REPRODUCTION COMPLEX (1983)

    Notes: The growth and reproduction complex contains recessive genes (grc) which influence body weight and gonadal development. Homozygous males are sterile, and they have an arrest of spermatogenesis at the primary spermatocyte stage. Homozygous females are fertile but have a reduced reproductive capacity. The data presented in this paper show that the latter defect is associated with a decrease in the relative number of secondary ovarian follicles and an increase in the number of atretic follicles. This finding indicates that most of the primary follicles do not mature properly. Thus, the genetic defect in gametogenesis controlled by the grc appears to occur at the same stage of development in both females and males.

    Notes: The contribution of cytochrome and alternative pathways to respiration during soybean [Glycine max (L.) Merr. cv. Chippewa 64] seed formation and maturation was measured by oxygen consumption of embryonic axis and cotyledon tissues and of mitochondria isolated from immature seeds. Respiration rates (dry weight basis) declined duing the last month of seed maturation. Cyanide sensitive respiration (cytochrome pathway) accounted for 80 to 90% of total oxygen consumption throughout seed formation and maturation. The proportion of the total respiration resistant to 1 mM cyanide and inhibited by 1 mM salicylhydroxamic acid (alternative pathway) did not exceed 6%. A residual oxygen consumption, accounting for 5 to 15% of total respiration, persisted in the presence of both inhibitors. Likewise, virtually no alternative respiration was found in mitochondria prepared from immature seeds. The alternative respiratory pathway seems absent during soybean seed formation and maturation regardless of whether grown in the greenhouse or field.

    Chlorobenzene biodegradation under consecutive aerobic–anaerobic conditions (2004)

    Notes: The biodegradation of monochlorobenzene, the main contaminant in a quaternary aquifer at Bitterfeld, Central Germany, was studied in microcosm experiments employing either original groundwater or defined mineral media together with the indigenous microbial community from the polluted site. The impact of consecutive aerobic–anaerobic–aerobic incubations on monochlorobenzene biodegradation, microbial diversity, and pH development was examined. The related changes in microbial community composition were analyzed by 16S rRNA gene-based single-strand conformation polymorphism (SSCP) fingerprints and sequencing of dominant bands and by quantitative analysis of bacterial respiratory chain quinones as biomarkers. Under aerobic conditions, the indigenous microbial community of the groundwater degraded monochlorobenzene mainly via the modified ortho-pathway. Respiratory chain quinones and SSCP analysis suggested dominance of the genera Acidovorax and Pseudomonas. A shift to anoxic conditions resulted in monochlorobenzene biotransformation but no dechlorination. The ability to degrade monochlorobenzene aerobically remained preserved throughout a fortnightly anoxic period at sufficiently high buffer capacity. Acidification, caused by monochlorobenzene biodegradation, was alkalinity-controlled. At low initial alkalinity a substantial decrease in pH, monochlorobenzene degradation, and total counts of live cells, accompanied by a change of the microbial community composition, was observed.

    Notes: -D-Glucurono-3,6-lactone and L-cysteine combine in a highly stereoselective manner to give the 7,5-bicyclic thiazolidinlactam 2. The α-hydroxy group of the D-glucurono-3,6-lactone was exchanged for an amino function (to give 13) and, after condensation with L-cysteine methyl ester, the polyol dipeptide 7 was obtained. Peptide couplings proceed without the need to protect the three secondary hydroxy groups of the seven-membered ring. The amino group of 7 was deprotected and selectively elongated to the pseudo-tripeptide 16. The depsipeptide 17 was obtained by condensation of Boc-Ala-OH with the polyol 2. Elongation at the carboxy terminus yielded 19 and 20. The bicyclic scaffold populates a well-defined solution conformation; the hydroxy groups mimic the side chains of hydrophilic amino acids and can be further functionalized.

    Notes: Water mobility in an acid Nafion® membrane containing ca. 15% water by weight has been studied by high-resolution neutron quasielastic scattering (NQES). The data are analyzed in terms of simple models. On a scale of ca. 10 Å, the water molecules move practically as freely as in bulk water, but their long-range motion is much more hindered. These results are important for an understanding of the relation between the microstructure and the macroscopic properties of these membranes. To our knowledge, this is the first detailed NQES study of the water-polymer interaction problem.

    Description / Table of Contents: Photoelectron Spectroscopy on Niobium IodidesThe photoelectron spectra (AlKα, HeI) of NbI5, NbI4, Nb3I8, Nb6I11, HNb6I11, Nb6I8(CH3NH2)6, Nb6I8(C3H7NH2)6, and Nb are measured and discussed. It is shown that the binding energy of the niobium core levels depends linearly on the oxidation number n (n = I/Nb). The relation BE = 201.8 + 1.07 · n holds for the Nb 3d5/2 level. Using this relation the hydridic character of the hydrogen in HNb6I11 becomes plausible and the increased electron concentration of the Nb6I8 cluster in the compounds Nb6I8(CH3NH2)6 and Nb6I8(C3H7NH2)6 is verified. Energy gaps Eg = 0.40 (0.45) eV are found for Nb6I11(HNb6I11) and for the amines the top of the valence band is 0.70 (CH3NH2) and 0.68 eV (C3H7NH2), resp. below the Fermi level.
    Notes: Es werden die Photoelektronenspektren (AlKα, HeI) von NbI5, NbI4, Nb3I8, Nb6I11, HNb6I11, Nb6I8(CH3NH2)6, Nb6I8(C3H7NH2)6 und Nb gemessen und diskutiert. Es läßt sich zeigen, daß die Bindungsenergie BE der Niob-Rumpfniveaus linear von der Oxydationszahl n (n = I/Nb) abhängt; für das Nb 3d5/2-Niveau ergibt sich die Beziehung BE = 201,8 + 1,07 · n. Durch Anwendung dieser Beziehung wird der hydridartige Charakter des Wasserstoffs in HNb6I11 wahrscheinlich gemacht sowie die Zunahme der Elektronenkonzentration im Nb6I8-Cluster der Verbindungen Nb6I8(CH3NH2)6 und Nb6I8(C3H7NH2)6 belegt. Für Nb6I11(HNb6I11) ergibt sich eine verbotene Zone Eg = 0,40 (0,45) eV, für die Amine ist der Abstand der Oberkante des Valenzbandes zur Fermi-Kante 0,70 (CH3NH2) bzw. 0,68 eV (C3H7NH2).

    Description / Table of Contents: Darstellung, Eigenschaften und ESCA-Charakterisierung von Vanadium-Oberflächenverbindungen an Silicagel. IV 2p3/2-Bindungsenergiewerte (BE) von 18 Vanadium-Verbindungen in Sauerstoff- und Chlorumgebung wurden ermittelt. Bindungsenergien in Abhängigkeit von der Oxidationszahl wurden hinsichtlich eines linearen Zusammenhangs kritisch überprüft, um so geeignete Modellverbindungen für Vergleichstandards auswählen zu können.Im allgemeinen beobachtet man bei einer Zunahme der formalen Oxydationszahl auch eine Erhöhung der Bindungsenergiewerte; im Einzelfall kann dies aber durch elektronenschiebende/ziehende Liganden überdeckt werden.Die mit Hilfe eines Computerprogramms durchgeführte Subtraktion des überlagernden O 1s Satellitenpeaks verbesserte die Genauigkeit der Vanadium 2p3/2-Bindungsenergiewerte erheblich in Oberflächenverbindungen.Die gefundenen Bindungsenergiewerte für (≡Si—O)3V=O(I), (≡Si—O)3V(II) und (≡Si—O)3V—(O2) (III) zeigen im Vergleich zu den trägerfreien Standardverbindungen eine BE-Erhöhung um 2,1 eV und damit die ausgeprägte elektronenziehende Wirkung des Trägermaterials auf das Vanadium in Oberflächenverbindungen. Über ESCA-Daten eines Oberflächen-Peroxokomplexes (III) wird zum ersten Male berichtet; einige Folgerungen der Ergebnisse werden diskutiert.
    Notes: Binding energies (BE) of 18 pure vanadium compounds (V 2p3/2 niveau) were measured in selected oxygen and chlorine environments, linearity of BE vs. oxidation states scrutinized and appropriate model compounds chosen as comparative standards.The general trend is an increase of BE with formal oxidation state; in particular, it could be counterbalanced by electron donating/withdrawing ligands on the V atom.A graphical (computerized) background substraction method was utilized to remove an interfering O 1s satellite peak and to enhance accuracy of BE values in surface compounds.BEs of (≡Si—O)3V=O (I), (≡Si—O)3V (II), and (≡Si—O)3V—(O2) (III) were determined. By comparison to standards positive BE shifts of about 2.1 eV were derived indicating the strong electron withdrawing (“electron sink”) effect of the support on V in surface compounds. This is the first reported ESCA data on a surface peroxo complex, (III). Some implications of the results are also discussed.
