  2. Parnassius apollo last-instar larvae development prediction by analysis of weather condition as a tool in the species' conservation.

    Comptes Rendus Biologies 337(5):325 (2014) PMID 24841959

    We combined developmental data obtained previously for the last-instar Apollo larvae (collected in 1996, 1997, and 2003) with corresponding meteorological data to assess the effects of ambient temperature and rainfall episodes on the duration and the completion of the instar. For comparing the tempe...
  3. Sex expression and reproductive biology in a tree species, Fraxinus excelsior L.

    Comptes Rendus Biologies 336(10):479 (2013) PMID 24246889

    We investigated Fraxinus excelsior breeding system using field data collected in a natural population and in a seed orchard. First, we attested functional trioecy (co-occurrence of males, hermaphrodites and females), with males producing pollen, hermaphrodites producing both pollen and seeds simulta...
  4. Relevance of blood groups in transfusion of sickle cell disease patients.

    Comptes Rendus Biologies 336(3):152 (2013) PMID 23643398

    Blood groups are clinically significant in sickle cell disease (SCD) as transfusion remains a key treatment in this pathology. The occurrence of a delayed haemolytic transfusion reaction (DHTR) is not rare and is a life-threatening event. The main cause of DHTR is the production of alloantibodies ag...
  5. Post-transfusional iron overload in the haemoglobinopathies.

    Comptes Rendus Biologies 336(3):164 (2013) PMID 23643400

    We review the recent advances in evaluation and treatment of transfusional iron overload (IO). Results of the French thalassaemia registry are described. According to the disease, thalassaemia major or sickle cell anaemia, mechanisms and toxicity of iron overload, knowledge about IO long-term outcom...
  6. Spermiogenesis and the spermatozoon ultrastructure of Robphildollfusium fractum (Digenea: Gyliauchenidae), an intestinal parasite of Sarpa s...

    Comptes Rendus Biologies 335(7):435 (2012) PMID 22847010

    Spermiogenesis in Robphildollfusium fractum begins with the formation of a differentiation zone containing: two centrioles, each bearing striated rootlets, nucleus, several mitochondria and an intercentriolar body constituted by seven electron-dense layers. The two centrioles originate two free flag...
  7. [The fight against epizootics in the 21st Century].

    Comptes Rendus Biologies 335(5):356 (2012) PMID 22682353

    The fight against epizootics is today better organized. The tools, methods and strategies used work well and are constantly being improved, which is necessary since disease epidemiology is evolving extremely fast, dominated by a growing complexity associated to global changes and the emergence of ne...
  8. Obesity, insulin resistance and diabetes in the sand rat exposed to a hypercaloric diet; possible protective effect for IL1-β.

    Comptes Rendus Biologies 335(4):271 (2012) PMID 22578573

    Our aim was to investigate the acute effects of Interleukin-1β (IL-1β) and Interferon-γ (IFN-γ) on glucose-induced insulin secretion in normal lean sand rats maintained on their natural diet and in obese insulin resistant normoglycemic or type 2 diabetic animals after a 9-month high caloric diet. An...
  9. Permanence of a stage-structured predator-prey system with a class of functional responses.

    Comptes Rendus Biologies 334(12):851 (2011) PMID 22123086

    A stage-structured predator-prey system incorporating a class of functional responses is presented in this article. By analyzing the system and using the standard comparison theorem, the sufficient conditions are derived for permanence of the system and non-permanence of predators. Copyright © 2011...
  10. Visual and chemical cues in habitat selection of sepioid larvae.

    Comptes Rendus Biologies 334(12):911 (2011) PMID 22123093

    Our results showed that E. scolopes larvae made active choices among the four habitats tested (living coral, dead coral, macroalgae and sand), and that their selective choice was influenced by presence or absence of conspecifics on the habitat. Sensory experiments showed that E. scolopes larvae diff...
