The chloride requirement for photosynthetic oxygen evolution. Analysis of the effects of chloride and other anions on amine inhibition of the oxygen-evolving complex
(Elsevier, 1984-09-27)
In the presence of Cl-, the severity of ammonia-induced inhibition of photosynthetic oxygen evolution is attenuated in spinach thylakoid membranes (Sandusky, P.O. and Yocum, C.F. (1983) FEBS Lett. 162, 339-343). A further ...
Prostaglandin modulation of N-formylmethionylleucylphenylalanine-induced transmembrane potential changes in rat neutrophils
(Elsevier, 1984-07-20)
Prostaglandins of the E-series (PGEs) and PGI2 will inhibit formylmethionylleucylphenylalanine- (f-Met-Leu-Phe) induced lysosomal enzyme release and superoxide-anion (O-2) production by neutrophils. The inhibitory effects ...
Theoretical treatment of cholesterol monohydrate dissolution in Renex-690/ionic surfactant systems based on a physical model approach
(Elsevier, 1984-10)
The dissolution kinetics of cholesterol monohydrate in the presence of Renex-690 and ionic surface active agents (benzalkonium chloride and sodium dodecyl sulfate) are dramatically influenced by the addition of NaCl. The ...
Comment on enhanced Raman scattering from adsorbates on semiconductor surfaces
(Elsevier, 1984-11-02)
A recently published model of surface enhanced Raman scattering from adsorbed molecules on semiconductor surfaces is compared to our experimental results for amorphous carbon on PbTe. The model fails to account for the ...
Vibrational analysis of crystalline diketopiperazine--I. Raman and i.r. spectra
(Elsevier, 1984)
Raman and i.r. spectra have been obtained of diketopiperazine and five of its isotopic derivatives: (CONDCH2)2, (CONHCD2)2, (CONDCD2)2, (13CONHCH2)2 and (13CONDCH2)2. In addition to solution spectra and powder spectra at ...
A general procedure for mild and rapid reduction of aliphatic and aromatic nitro compounds using ammonium formate as a catalytic hydrogen transfer agent
(Elsevier, 1984)
Various aliphatic and aromatic nitro compounds were selectively and rapidly reduced to their corresponding amino derivatives in very good yield using anhydrous ammonium formate as a catalytic hydrogen transfer agent.
Are cationic [eta]3-allyl complexes general precursors to metallacyclobutanes? Synthesis and structure of [mu]-chloro-bis[([eta]3-allyl)-2,2'-bipyridyldicarbonylmolybdenum(II)] tetrafluoroborate
(Elsevier, 1984-08-28)
Silver tetrafluoroborate reacts with Cl(bipy)(CO)2([eta]3-C3H5)Mo in CH2Cl2 to give the dimeric cation, ([mu]-Cl)[(bipy)(CO)2([eta]3-C3H5)Mo]2+, isolated as the crystalline BF4- salt with CH2Cl2 of solvation (5). Complex ...
