  1. Evolution of hemocyte concentration in the melanogaster subgroup species.

    Comptes Rendus Biologies 327(2):139 (2004) PMID 15060985

    We explore two possible hypotheses about the ecological factors driving the evolution of hemocyte load in insects. The first is parasite infection risk, its variability and the genetic diversity of parasites. The other supposes that all the other factors of environmental stress drive the evolution th...
  2. [Experimental study on the sensory capabilities of coral-reef fish larvae for the recognition of their settlement location].

    Comptes Rendus Biologies 327(2):159 (2004) PMID 15060987

    Some experiments in aquarium and in situ have been carried out to investigate the sensory abilities of coral reef fish larvae in the recognition of their settlement location. Ten out 12 species studied detected their settlement location due to the presence of conspecifics and not by habitat character...
  3. Do spawn storage conditions influence the colonization capacity of a wheat-straw-based substrate by Agaricus subrufescens?

    Comptes Rendus Biologies 337(7-8):443 (2014) PMID 25103829

    Storage conditions of the spawn of edible fungi are of major importance to facilitate the production of mushrooms. Here, standard storage conditions at 10°C or 15°C were used and the potential of colonization of standard European compost by the tropical species Agaricus subrufescens was assessed dur...
  4. Phenotypic screening and molecular analysis of blast resistance in fragrant rice for marker assisted selection.

    Comptes Rendus Biologies 337(5):318 (2014) PMID 24841958

    Experiments were conducted to identify blast-resistant fragrant genotypes for the development of a durable blast-resistant rice variety during years 2012-2013. The results indicate that out of 140 test materials including 114 fragrant germplasms, 25 differential varieties (DVs) harbouring 23 blast-r...
  5. Ultrastructural and hormonal changes in rat cauda epididymal spermatozoa induced by Boswellia papyrifera and Boswellia carterii.

    Comptes Rendus Biologies 337(4):250 (2014) PMID 24702894

    Boswellia papyrifera and Boswellia carterii diffuses smoke polluting air that adversely affects indoor environment that certainly harm human health. Therefore, this study aims at ascertaining the effect of these plants on gonadal hormones and molecular changes in rat spermatozoa. The animals were ex...
  6. Metabolic diversity in the grains of Indian varieties of rice.

    Comptes Rendus Biologies 337(4):283 (2014) PMID 24702898

    The aim of the present work was to analyze metabolic diversity in 26 different indica varieties of rice grains. Seventy-six metabolites could be identified in the methanol extracts of each of the rice varieties analyzed by gas chromatography-mass spectrometry. These metabolites included 9 sugars/sug...
  7. Ultrastructural study of spermiogenesis in a rare desert amphisbaenian Diplometopon zarudnyi.

    Comptes Rendus Biologies 336(10):473 (2013) PMID 24246888

    Spermiogenesis, in particular the head differentiation of Diplometopon zarudnyi, was studied at the ultrastructural level by Transmission Electron Microscope (TEM). The process includes acrosomal vesicle development, nuclear elongation, chromatin condensation and exclusion of excess cytoplasm. In st...
  8. [Schistosomiasis caused by Schistosoma mansoni in the Kou valley: Characterization of the transmission system and socioeconomic impact].

    Comptes Rendus Biologies 336(5-6):284 (2013) PMID 23916204

    Schistosomiasis is one of the waterborne diseases which benefit from environmental and behavioral changes induced by the mobilization of surface water resources in Sahelian countries, such as Burkina Faso. Studies have established the existence of human schistosomiasis in the Kou valley, one of the...
  9. Hydroxycarbamide: clinical aspects.

    Comptes Rendus Biologies 336(3):177 (2013) PMID 23643402

    Due to its oral route of administration and mild toxicity profile, as well as its potent laboratory and clinical effects, hydroxyurea (or hydroxycarbamide) has been the primary focus of fetal hemoglobin (HbF) induction strategies for the treatment of children with sickle cell anemia (SCA). When admi...
  10. The New Microbiology: a conference at the Institut de France.

    Comptes Rendus Biologies 335(8):514 (2012) PMID 22938917

    In May 2012, three European Academies held a conference on the present and future of microbiology. The conference, entitled "The New Microbiology", was a joint effort of the French Académie des sciences, of the German National Academy of Sciences Leopoldina and of the British Royal Society. The orga...
