fragments of a Rabbit anti-F9 serum do not disturb cleavage of Mouse embryos in culture but prevent blastocyst formation. This effect is reversible for a few hours. It is observed neither with Fab fragments directed against another surface antigen of blastomers nor with monovalent concanavalin A. Radiobiology Interaction Between Thymic Cells and Hemopoietic Stem Cells. Enhanced Repopulation of the Irradiated Thymus, by Richard Daculsi, Elisabeth Legrand and Jean-François Duplan 1923 In irradiated mice engrafted with hemopoietic cells, the thymus is repopulated more rapidly by bone marrow-derived than by spleen-derived cells. Admixing thymic cells with the restorative suspension stimulates the thymic
Admixing thymic cells with the restorative suspension stimulates the thymic repopulation by spleen-derived cells whereas it has no effect on the repopulation by bone marrow-derived cells. Biochemistry Differential Thermal Analysis of the Organic Component of the Bone, by Guy Perinet, Raymond Lafont et Jean Amic 1927 Thermal decomposition analysis of Bovine femur bone has been carried out by means of a Micro Differential Thermal Analyser. The analysis of both thermograms and amino acid compositions has revealed the complexity of collagen degradation mechanisms. Pharmacology Gastric Ulcerative Lesions in the Rat: New Experimental Model and Tentative With a Triterpen Agent, by Christine
Experimental Model and Tentative With a Triterpen Agent, by Christine Lefournier, Alain Poizot and Paul de Saint-Maur 1931 An experimental model using restricted diet and exposure to cold for several weeks was devised. Following a two-week treatment with a triterpen healing agent, the rate of ulcerative lesion was significantly decreased. Microbiology New Contribution of Scanning Electron Microscopy to the Study of Yeasts of Protoplasts, by Michel Miegeville and Odile Morin 1935 Study by scanning electron microscopy enables us to describe with precision the morphology of protoplasts. We can confirm that the wrinkles more or less perceptible on the protoplasts studied,
the wrinkles more or less perceptible on the protoplasts studied, do belong to the morphology of those just mentioned, that the presence or the absence of globulous component is connected with the physiological activity of the cell and that it is possible to distinguish the different protoplasts thanks to their morphological aspect. Applied microbiology Steroids “survival factors” of yeasts during the process of alcoholic fermentation of grape must, by Suzanne Lafon-Lafourcade, François Larue, Paul Brechot and Pascal Riberau-Gayon 1939 Certain sterols (ergosterol) on one hand, oleanolic acid on the other, are survival factors of the yeast under certain wine-making conditions;
are survival factors of the yeast under certain wine-making conditions; they do not increase the growth rate of the cells, but allow them to remain in a viable state for a longer time and so prolong their fermenting activity. Each of them acts in a different way. Virology Protection Afforded by a Purified Neuraminidase in Intranasally Vaccinated Mice to Aerosol Virus Challenge, by Chantal Bottex, Daniel Robert and Robert Fontanges 1943 An intranasal immunization with a A/PR8/34-isolated NA, protected mice as well as the whole virus and A/Hong Kong/1/68 virus against a subsequent infection with mice-adapted A/PR8/34 strain. A Yam

A Yam Mosaic (Dioscorea cayenensis) Caused by a Filamentous Virus, in Ivory Coast, by Jean-Claude Thouvenel and Claude Fauquet 1947 A filamentous virus causes a yam mosaic that attacks almost all Dioscorea cayenensis in Ivory Coast. It was possible to transmit this virus only to Dioscoreaceae. This paper reports the biological properties of the virus, the clarification and purification tests, the electron microscope observations and the aphid transmission. This virus seems to be a new virus. The Protein Subunit of Beet Necrotic Yellow Vein Virus (BNYVV). Molecular Weight Estimation and Amino-acid Composition,
Yellow Vein Virus (BNYVV). Molecular Weight Estimation and Amino-acid Composition, by Charles Putz, Daniel Collot and Remy Peter 1951 By polyacrylamide gel electrophoresis it was possible to estimate the apparent molecular weight of the protein of the French BNYVV isolate to 21,000 + 1,000 daltons. This protein, whose composition is distinctly marked by the absence of cysteine, contains about 197 amino-acid residues. The N-terminal extremity of the protein chain seems to be acetylated. These results will allow the further study of the BNYVV structure. Immunochemistry Antigen Binding Capacity of Lobster Muscle Arginine Kinase and of its Cyanogen Bromide Fragments, by
Muscle Arginine Kinase and of its Cyanogen Bromide Fragments, by Yves Benyamin, Yvonne Robin and Frangoise Regnouf 1955 The antigenic saturation of lobster arginine kinase (38 000 daltons) by its specific antibodies has been studied. It was found that seven antigenic binding sites are simultaneously reactive on the surface of the enzyme in the presence of a large excess of antibodies or of their Fab fragments. After cyanogen bromide cleavage, the antigenic reactivity is distributed on several fragments of various sizes. Cancerology Interdependent Action of Nickel Sulphate and X-Rays on Human Lymphoblastoid Leukemic Cells, by Jacques Bensimon 1959 In a
Human Lymphoblastoid Leukemic Cells, by Jacques Bensimon 1959 In a first experiment, cells were cultured in media supplemented by nickel sulphate, irradiated in the same media and cultured in the same media after irradiation. In a second experiment, cells were cultured during 18 hrs. in media supplemented by nickel sulphate, and then cells were washed and cultured in normal media where they were irradiated. The nickel sulphate toxicity appears as a increasing function of the nickel sulphate concentration and the nickel sulphate action endurance. The nickel sulphate toxic effect is amplified by X-Rays. This amplification is a time function that
amplified by X-Rays. This amplification is a time function that depends on the X-Ray dose, nickel sulphate concentration and period of time from the outset of culture to the irradiation. The nickel sulphate toxic effect appears faster when nickel works after X-Rays. COMPTES RENDUS HEBDOMENAIRE DES SÉANCES DE L'ACADÉMIE DES SCIENCES CONTENTS VOLUME 284 — SECTION D No. 20 — SESSION OF MAY 23rd 1977 Geology Palynological and Stratigraphical Date on the Plio-Pleistocene Transition at Trapeza Section (Corinthia-Greece), by Jacqueline Sauvage and Michel Sebrier 1963 The progressive passage from the summit of the Pliocene to the Lower Pleistocene (defined by
summit of the Pliocene to the Lower Pleistocene (defined by the presence of pre-Tiglian Flora) has been observed in the Trapeza section near Kalamaki. The end of the Pliocene is characterized by a "Corinthian" microflora phase. Thus it would appear that certain Calabrian and "Apscheronian" macrofauna are older than the pre-Tiglian. Structural Geology Structure of the Lapland Granulite Arc (Fennoscandia), by Pierre Barbey, Raymond Capdevila, Pierre Choukroune and Jean Hameurt 1967 The structure of the Lapland granulite arc is the result of two main phases of deformation: — the first producing megascopic recumbent folds, overturned towards the south-west; — the
producing megascopic recumbent folds, overturned towards the south-west; — the second controlling mesoscopic structures overturned towards the north-east, and characterized by tensional faulting at depth and gravity slide similar folds nearer the surface. Different metamorphic events can be correlated with the structural evolution. Quaternary Geology On the Quaternary of Lattakia area (Syria), by Jacques Besançon, Lorraine Copeland, Francis Hours and Paul Sanlaville 1971 Cut out between two sloped platforms which still bear numerous evidences of old shorelines (at 80, 130 et 180 m), the Nahr el Kebir river has built five successive terraces, the oldest of which is to be
five successive terraces, the oldest of which is to be found at + 120 m. A large number of artefacts are connected with the marine and fluviatile deposits and throw light on the evolution of the Lower Palaeolithic. A chronology is here suggested. Tectonics Formation of the Alps between Ivrea and Geneva, by André Amstutz 1975 A typical section of the broad valaisan-valdotain segment shows the structures and indicates the sequence of movements which created them; the subduction MR under SB being at the beginning and not at the end of the Alpine tectogenesis. The transition zone with the Ossola-Tessin
of the Alpine tectogenesis. The transition zone with the Ossola-Tessin segment is also considered, with the huge transverse fold of the SB/MR complex, not understood by the two opposing conceptions which have previously attempted to account for this zone. Paleontology Positive Dating of Antenatal Human Remains from Suard, Chaise de Vouthon (Charente), by Thermoluminescence, by Max Schvoerer, Jean-François Rouanet, Henry Navailles and André Debénath 1979 Thermoluminescence has permitted us to get a first absolute dating of pre-neanderthal human remains. Used to determine the "age of a burnt stone, a biotite microgranite, thermoluminescence has given an age of 126,000 ± 15,000
microgranite, thermoluminescence has given an age of 126,000 ± 15,000 years B.P. Botany Comparison of Weight and Germinative Properties of Wheat Spikelet Seeds (Triticum aestivum) With Those of Aegilops ovata Spikelet, by René Chaussat 1983 The basic grain of the spikelet of Aegilops ovata L. is less heavy and germinates less rapidly than that located in terminal position. This "acrotone" behaviour is equally to be seen in wheat and must result from correlative phenomena in the process of grain formation. Plant Morphogenesis Morphogenesis in Gleditsia triacanthos L. Influence of the Shoot Meristem and of the Upper Leaf Primordia on the
Shoot Meristem and of the Upper Leaf Primordia on the Leaf Growth and Morphogenesis, by Mohamed Amer and Pierre Neville 1987 The shoot meristem partly inhibits the growth of leaves initiated by it. The new leaf primordia which it forms after initiation of a given leaf, also contributes to the inhibition of the latter. These various influences are not only quantitative but also are slightly morphogenous since they lead to leaf structure simplification. Plant Histophysiology Effects of several growth regulators associated with various photoperiodic cycles on floral induction of neoformed buds of Cichorium Intybus L., by Jacques Margara 1991 Neoformed
buds of Cichorium Intybus L., by Jacques Margara 1991 Neoformed buds on root explants of Cichorium Intybus have been used as an experimental model for studies on photoperiodism. Cichorium Intybus is a long day plant with a critical day length of about 13 hours. When cultures are submitted to cycles of 24 h consisting of 12 h of night and 12 h of dark no flowering is observed. Interruption of a dark period of 12 h by 2 h of light provokes floral initiation exclusively when the 2 h of light are given in the middle of the night. Cycles
light are given in the middle of the night. Cycles of 6 h of light alternating with 6 h of dark do not elicit floral initiation. Under unfavourable photoperiodic conditions N-dimethylamino succinamic acid (B95 10-4 M) promotes floral initiation. Indolylbutyric acid (AIB 10-5 M) inhibits neoformation of inflorescence buds. In these conditions gibberellic acid (GA3 10-5 M) does not promote flowering. But we know that GA3 can elicit floral initiation when continuous illumination, optimal for photoperiodic induction, is associated with lack of vernalization and nutritional deficiency. Zoology Setiferous system of Decapod Crustaceans. Elements of a general classification, by Pierre Drach
Decapod Crustaceans. Elements of a general classification, by Pierre Drach and Francoise Jacques 1995 The setae are considered individually, i.e. independently of their respective arrangement and of their topographical distribution. Their characteristics can be recorded on analytical cards on which 15 hierarchically classified features are noted as «present» or «absent»). Following this analysis, a general classification is proposed. Entomology Existence of Pliant Fore-Wings in the Tragopan Membracidae (Homoptera), by Michel Boulard. 1999 The Tragopan Membracidae, a small group of neotropical Homoptera, possess fore-wings which can be folded up while at rest. The folding up, which is brought about by two
rest. The folding up, which is brought about by two types of transverse folding, constitutes a biological occurrence that is exceptional in the class Insecta: the only known analogue is found in the Plastaspidae Hemiptera. The existence of pliant fore-wings in the Tragopan Membracidae seems to be connected to the peculiar development of the pronotum which tends to take in all the body. Protistology Synthesis of DNA in a Foraminifer, Iridia lucida Le Calvez during Gamogony, by Denise Césari... 2003 Some Iridia lucida, Le Calvez, at various stages of their gamogony, were subjected to incorporations of 3H-thymidine. The experiment was
gamogony, were subjected to incorporations of 3H-thymidine. The experiment was carried out to detect whether any DNA was synthesized in the interphasic micronuclei and to show that their division follows the stages of a typical mitosis. Insect Physiology A Synthetic Sex Attractant for Sparganothis pilleriana (Schiffermüller), by Philippe Saglio, Ernst Priesner, Charles Descoiris and Martine Gallois 2007 E-9 dodecenyl alcohol (E-9 DDOl) and E-9 dodecenyl acetate (E-9 DDA) are the two most active compounds among those tested by electroantennography on the male antennae of Sparganothis pilleriana. Mixtures of these two compounds containing 10 to 20 % of E-9 DDOl for
compounds containing 10 to 20 % of E-9 DDOl for 90 to 80 % of E-9 DDA are able to induce in an olfactometer a characteristic sexual behaviour of the male moth. They must constitute a potential synthetic sex attractant for monitoring these insect populations in vineyards. Comparative Physiology The Gill Vasculature in the Eel: Action of Acetylcholine and Epinephrine on the Distribution of a Polymerisable Resin in the Different Vascular Compartments, by Suzanne Dunel and Pierre Laurent. 2011 The current findings from gill vascular cast preparations in the eel emphasize the division in each primary lamella of the afferent
emphasize the division in each primary lamella of the afferent vasculature into two efferent pathways: an arterial pathway (via the secondary lamellae and the efferent branchial artery to the dorsal aorta), a venous pathway (via the central lamellar compartment and the branchial vein to the sinus venosus). By the same technique two antagonist mechanisms have been shown presumably controlling the blood flow in both pathways. 1. Acetylcholine increases the filling of the central lamellar compartment by constricting the efferent arterial sphincters and therefore increases the venous return. 2. Epinephrine impairs the filling of the central lamellar compartment (by acting on
the filling of the central lamellar compartment (by acting on β receptors) and dilates the arterial pathway (by acting on α receptors). Therefore the stimulation of these two synergistic receptors by epinephrine increases the systemic blood flow. Cellular Biology Stimulation of Synthesis and non Competitive Inhibition of Alkaline Phosphatase in Normal Hamster Fibroblasts and Absence of this Response in Transformed Fibroblasts, by Cécile Mazière and Jean-Claude Mazière 2015 Theophylline increases the synthesis of alkaline phosphatase in normal Hamster fibroblasts (activity x 6 after 24 hours with theophylline 10-3 M). The enzymatic activity of these cells is inhibited by theophylline in
enzymatic activity of these cells is inhibited by theophylline in vitro (80% inhibition in the presence of theophylline 10-3 M). The inhibition seems to be non competitive, since the apparent Km of the enzyme is not modified. This stimulator and inhibitor effect of theophylline is absent in Hamster fibroblasts transformed by SV 40 virus. Isolation and Purification of Membrane Fractions in Perinereis cultrifera Oocytes (Polychaetes, Annelids), by François Caner, Maurice Porchet, André Dhainaut and Claude Dissous 2019 A cell fractionation procedure is described which allows the preparation and the purification from Perinereis cultrifera of oocyte envelopes and dictyosomes. Electron microscope
from Perinereis cultrifera of oocyte envelopes and dictyosomes. Electron microscope examinations revealed that morphology of both membrane fractions were very similar to that observed in situ. Mucous compounds of cortical alveoli were also purified. Enzymological Embryology Electrophoretic Analysis of Intestinal N-Acetyl-P-Glucosaminidase During Larval Development and Metamorphosis of Discoglossus pictus, by Jacques Hourdry 2023 Polyacrylamide gel electrophoresis of gut preparations has permitted us to separate 2 isoenzymes of N-acetyl-β-glucosaminidase (G1, and G2), during larval development and metamorphosis of Discoglossus pictus. The G1/G2 ratio of the total and soluble activities increases up to climax. Mycology Effects of Lake Leman Pollution on Invertebrate

Mycology Effects of Lake Leman Pollution on Invertebrate Fauna: Accumulation of Tin in Annelids, Molluscs and Arthropods, by Roger Martoja, Micheline Martoja, Christiane Ballan-Dufrancais, Anne-Yvette Jeantet, Denise Lhonoré, Jacques Zotonorc and Michel Truchet 2027 Among 61 invertebrates collected in the lake Leman in July and October 1976, 36 animals from 14 families of Annelids, Molluscs and Arthropods showed a above-normal level of tin. Metal was present in several organs, mainly in the epidermis and exoskeletons. No histological damage was found. Radiobiology Effect of cephalic irradiation on adult rabbits' lymphoblastic transformation capacity, by Paule Servant, Jean-Yves Perrot, Jean-Louis Bourgain,
lymphoblastic transformation capacity, by Paule Servant, Jean-Yves Perrot, Jean-Louis Bourgain, Gerard Perrault and Christian Pasquier 2031 The temporary immunological depression previously demonstrated after high level head irradiation of adult rabbits seems to be due to decrease in lymphoblastic transformation capacity connected with encephalon injury. by Marie-Claude Giess 2035 Two strains of Drosophila were irradiated with 25 to 75 Krads of 60 Co gamma rays at a dose rate of 1 000 rad/min. on the fourth day of imaginal dormancy. A radiosensitivity difference between the strains was observed. However, the influence of sex was similar in the two strains, the females
of sex was similar in the two strains, the females being more sensitive than the males. Biochemistry Differential Thermal Analysis of Fossil Bones, by Raymond Lafont, Guy Perinet, Nicole Petit-Maire and Jean Amic 2039 D.T.A. of some fossil bones has revealed that this method allows an easy checking of collagen degradation in the geological environment. Particularly there is a satisfying correlation between the presence or absence of hydroxyproline and the thermogram shape. Enzymatic Differences in Mycobacteria. Ribitol Dehydrogenase, by Anatole Andrejew, Marie-Thérèse Orfanelli and Jean Desbordes 2043 Contrary to the tubercle Bacilli (H3, Ra, BCG), Mycobacterium phlei has a ribitol-NAD
tubercle Bacilli (H3, Ra, BCG), Mycobacterium phlei has a ribitol-NAD dehydrogenase (that also oxidizes, although to a lesser extent, erythritol and glycerol). This difference is observed with the Bacteria grown on Sauton's medium, as well as after their adaptation to ribitol. The extracts of all these Mycobacteria reduce, NADP in the presence of glycerol, ribitol or erythritol, though very slowly. On the differentiation between the bisexual and parthenogenetic forms of Polyxenus lagurus (L.) (Diplopoda. Penicillata) based on the use of Proteinograms, by Monique Nguyen Duy-Jacquemin and Max Goyffon... 2047 Disc-electrophoreses are carried out from homogenates of Polyxenus lagurus. An obvious

An obvious difference concerning two proteinic fractions is noted between the bisexual form and the parthenogenetic one; on this basis two species can be differentiated. Microbiology Bacillus thuringiensis var. pakistani: a New Sub-Species Corresponding to Serotype 13, by Huguette de Barjac, Véronique Cosmao-Dumanoir, Rafi Shaik and Gabriel Viviani 2051 A new sub-species of B. thuringiensis is described on the basis of a new flagellar antigen: HI3 and of several differential biochemical characters. The name pakistani is proposed for this variety which has been isolated from Insects in Pakistan. Transfer of Listeria monocytogenes

Transfer of Listeria monocytogenes Pathogenicity from a Virulent to an Avirulent Strain, by Michel Cormier 2055 The pathogenicity of a virulent strain of Listeria monocytogenes was transferred to an avirulent strain by mixing the filtered culture of the pathogenic strain with an exponentially growing avirulent strain. Virology Affinity Chromatography Purification of Surface Antigens from Myxovirus Influenzas, by Chantal Bottex, Pierre Bienvenu and Robert Fontanges 2059 Surface antigens of Myxovirus Influenzas A/PR 8/34 and A/Hong Kong 1968 were isolated on Fetuin covalently attached to Sepharose. The amino acid composition of isolated neuraminidases was determined. Immunology
The amino acid composition of isolated neuraminidases was determined. Immunology Cytotoxicity of Human EBV-Sensitized T-Lymphocytes Role of HLA Antigens at the Target Cell Surface, by Thomas Tursz, Wolf H. Fridman, Andreas Tsapis, Anna Senik and Marc Fellous 2063 Peripheral lymphocytes from patients with infectious mononucleosis are cytotoxic towards target cells from Epstein-Barr virus-genome carrying human lymphoblastoid lines. Thus, these T-cells appear to be sensitized to viral coded determinants. Daudi cells, that carry EBV-genome, but lack HLA antigens are resistant to specific cytolysis in this model. These results suggest direct HLA involvement in the target structure recognized by virus-sensitized cytolytic T-lymphocytes
involvement in the target structure recognized by virus-sensitized cytolytic T-lymphocytes in human. Ils sont rares dans les structures d'impact, beaucoup en sont dépourvus, et c'est le cas de celles qui nous intéressent. Les éléments planaires décorés C) : les discontinuités sont le fait de l'arrangement planaire de petites inclusions fluides (fig. 1 à 4). DONNÉES NOUVELLES. — 1. Inclusions fluides. — L'étude microthermométrique des inclusions fluides liées aux éléments planaires des quartz de Carswell (4) et Charlevoix [(4), (8)] montre que la solution est aqueuse, de faible salinité. Elle indique que ces inclusions se sont formées toujours à basses pressions,
que ces inclusions se sont formées toujours à basses pressions, dans une large gamme de températures, d'abord supérieures à 500°C (8) puis à températures décroissantes. De tels fluides n'ont jamais été décrits dans les roches volcaniques. D'autre part, les inclusions préexistantes ont subi des modifications, notamment une fracturation. Dans l'hypothèse d'un phénomène endogène, une mise en compression serait accompagnée par une microfracturation avec piégeage de fluides à densité beaucoup plus élevée. Ces données signifient que les inclusions ne se sont pas formées durant le stade de compression qui est très bref dans un phénomène d'impact (10-9 s à 10-4 s
bref dans un phénomène d'impact (10-9 s à 10-4 s [(3), (5)]), mais après le retour à la pression normale, à température élevée. 2. Études au microscope électronique à balayage (M.E.B.). — Les premières observations portant sur les quartz à éléments planaires décorés des brèches de Rochechouart [e), (9)] se retrouvent pour ceux de Carswell (fig. 5 à 8). À cette échelle, le monocristal de quartz (taille de l'ordre du millimètre par exemple) apparaît constitué par l'assemblage ordonné de très nombreux petits cristaux de quartz alignés, de même taille (de l'ordre de la dizaine de µm), et de même orientation
