The author describes recent advances in the chemistry and the pharmacology of African Strychnos. Emphasis is given to the study of leaves of Strychnos usambarensis which contain a series of new molecules (strychnopentamine, strychnofoline, usambaridines ( hydroxyusambarines) A further novel alkaloid (akagerine ) is also identified from the roots of the same species colected in the National Park of Akagera in Rwanda. .

Influenza PR8 particles resulting from strong treatment with caseinase C are spikeless, devoid of neuraminidase and hemagglutinin 1 and 2 glycopeptides, and contain a Schiff-neg. polypeptide of about 13,000 mol. wt. which exists as traces in intact virions. Their M-protein polypeptide content is reduced to 50% of its original value, but there is no evidence of particle disruption nor of lipid release. They fix complement in the presence of both anti-M-protein and antiserum raised against a host polysaccharide. During exposure to caseinase C, an antigen is unmasked. It is type-specific and its identity with the M-protein is discussed [less ▲]

Auroral ultraviolet spectra in the range from 1200 to 3200 A have been obtained by the spectrometer on board the OGO-4 satellite. Emissions of N2, H, O, and N are readily identified. Atomic and molecular intensities are deduced from the comparison with a synthetic spectrum and compare reasonably well with some previous measurements and calculations. A feature at 2150 A is assigned to the (1-0) NO gamma band. Taking into consideration the various excitation mechanisms of NO(A2 Sigma), it is proposed that energy transfer from N2 metastable molecules to oxygen accounts for the excitation of the NO gamma bands. In particular, it is suggested that the resonant reaction between O2 and highly metastable N2 molecules may be a major source of NO(A2 Sigma). [less ▲]

The bimetallic µ-oxo-alkoxides are highly active for lactone ring-opening polymerization. These compounds are aggregated in solution and their mean degree of association depends on the nature of alkoxide groups, metals, and solvent; it is modified by addition of suitable ligands or temperature variations. The course of the lactone polymerization is strongly related to the structural features of the catalyst. The determination of the mean number of growing chains per catalyst molecule, the study of the polymerization kinetics, and the knowledge of the catalyst behavior during the monomer conversion have contributed to an understanding of the polymerization mechanism.

Les expériences de Harlow ont montré que pour survivre, puis adopter des conduites sociales et sexuelles adéquates, le jeune primate devait rencontrer en temps utile des stimuli déterminés dont la constellation est inscrite dans la mère actuelle. Celle-ci possédant tous ces stimuli simultanément, les présente en permanence au petit qui réagit à ceux qui lui conviennent à chaque moment de son évolution. A l'origine, le besoin d'accrochage du petit à un épiderme velu et impérieux, puis se nuance progressivement pour devenir le désir de contact rapproché avec sa mère. L'existence d'une phylogenèse commune au primate et à l'homme permet de penser qu'il est vraisemblablement de même pour les petits humains. Dès lors, la réaction du sujet face à l'estompage considéré en tant que stimulus signifiant "velu" pourrait nous informer des types de contact auxquels il a pu accéder et dont il a tiré du plaisir. Ainsi, les interprétations traditionnelles des différentes réponses-estompage (E, EF, FE) - interprétations dont la plupart étaient et restent satisfaisantes - trouvent dans l'éthologie des primates un fondement cohérent.
