Strychnos innocua is frequently cited in African traditional medicine. Root bark has been chemically screened.A small amount of alkaloids was detected as well as loganic acid. The plant contains at least two alkaloids that are devoid of an indole skeleton. The authors suggest that they are monoterpenic and not very different from gentianine. However the products would not be artefacts because ammonia was not used for alkalinization before the extraction [less ▲]

Dissociative ionization in O2 has been examined by means of a retarding potential lens combined with a quadrupole mass spectrometer. This particular arrangement made possible detailled analysis of the O+ ions kinetic energy distribution and the measurement of threshold energies of O+ ions with known kinetic energy. These two types of informations bring new experimental evidence, besides direct dissociative ionization of O2, for predissociation of the B2Sigma-/g state, the 2Piu state and the c4Sigma-/u state of O2+. A new predissociation of the O2+(2Deltag) state has been found. At low ion energy the predissociation of the 2Phiu state or an autoionizing predissociation is observed. [less ▲]

Dans le cadre de l'étude de transit gastro-intestinal chez les polygastriques, cet article présente un modèle mathématique empirique pour décrire l'évolution de la concentration fécale en traceur radioactif qui suit un marquage instantané. Ce modèle permet notamment de calculer le temps mis en moyenne par une particule pour traverser le tube digestif. [less ▲]

Following a brief review of HELMHOLTZ's principle and of the analogy relating KIRCHHOFF's plate bending theory and a STOKES flow, such a flow is analyzed in a channel presenting periodically crenelated cavities. The results show clearly that for sufficiently deep cavities vortices are generated even at very low REYNOLDS numbers. [less ▲]

The processing of erythrocyte iron by the reticuloendothelial cell has been characterized by kinetic measurements of blood radioactivity made after the intravenous injection of heat-damaged erythrocytes labeled with 59Fe and of transferrin-bound 55Fe. The early reticuloendothelial release of iron, a matter of hours, was calculated from the plasma turnover rate of 55Fe and the plasma reappearance of 59Fe. Late release was calculated from the ratio of the cumulative incorporation of both tracers into the circulating red cell mass over a period of 2wk. There was an initial processing period within the reticuloendothelial cell, after which radioiron either rapidly returned to circulation (t 34 min) or was transferred to a slowly exchanging pool of storage iron within the reticuloendothelial cell (t release to plasma of 7 days). These pathways were of equal magnitude in the normal dog. Reticuloendothelial release of iron was largely independent of the pre-existing plasma iron level or transferrin saturation. Diurnal fluctuations in the plasma iron level were shown to be the result of a variable partitioning of iron between the early and late release phases. Acute inflammation resulted in a prompt and marked increase in the fraction of iron stored (late phase), whereas depletion of iron stores resulted in a marked increase in early release. [less ▲]

The bacterial target of beta-lactam antibiotics consists of a set of multiple, membrane-bound receptors. Some of them have been characterized as DD-carboxypeptidases. The DD-carboxypeptidases catalyse the opening of amide bonds and transfer the carbonyl carbon to an exogenous nucleophile, and are specifically designed to operate on the D-Ala-D-Ala linkageof L-R-D-Ala-D-Ala terminated peptides (where R is most often a diamino acid residue). The R61, R39 and several Bacilli DD-carboxypeptidases are known to be serine-enzymes and the G DD-carboxypeptidase has been characterized as a metallo (Zn ions) enzyme. Both the R61 and the G enzymes have been crystallized. In turn, the S. faecalis 43,000-Mr DD-carboxypeptidase, which is inhibited by low dose levels of pCMB, might be a thiol-enzyme. The goal pursued is the understanding of the mechanistic properties and functioning of the active centers of the DD-carboxypeptidases at the molecular and atomic levels. The research program involves 1) further characterization of the S. faecalis enzyme (which can be obtained in a water-soluble form); 2) isolation of various Streptomyces membrane-bound enzymes in a truly water-soluble form; 3) sequencing of the G and R61 enzymes; 4) the 2.8 A structure analysis of the G enzyme. (A similar study is conducted by Dr. J.R. Knox at the University of Connecticut, on the R61 enzyme, which enzyme is prepared and purified in this laboratory and then sent to Storrs); 5) conformational studies and quantitative structure activity relationships (QSAR).
