  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. On the biology of Spiruroidea parasites of murine rodents on El Hierro (Canary Islands, Spain) with molecular characterization of Streptopha...

    Comptes Rendus Biologies 336(9):440 (2013) PMID 24161241

    This paper reports the role of darkling beetles Pimelia laevigata costipennis and Hegeter amaroides (Tenebrionidae) as intermediate hosts of spiruroid nematodes parasites of the black rat and house mouse of El Hierro (Canary Islands). Larvae of spiruroid species were found in the two tenebrionids (1...
  4. Leaf colleters in Tontelea micrantha (Celastraceae, Salacioideae): ecological, morphological and structural aspects.

    Comptes Rendus Biologies 336(8):400 (2013) PMID 24018197

    The colleter secretion can be useful to protect plants of Cerrado (Brazilian savanna) biome during the long and pronounced dry season. This study describes the presence of colleters in Tontelea micrantha and represents the first record of these structures in Celastraceae. To investigate colleter str...
  5. [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...
  6. Chaotic dynamics of a three species prey-predator competition model with bionomic harvesting due to delayed environmental noise as external ...

    Comptes Rendus Biologies 335(8):503 (2012) PMID 22938916

    We consider a biological economic model based on prey-predator interactions to study the dynamical behaviour of a fishery resource system consisting of one prey and two predators surviving on the same prey. The mathematical model is a set of first order non-linear differential equations in three var...
  7. Alteration of dopaminergic innervation and voluntary movements after long period of thirst in a semi-desert rodent, Meriones shawi: behavior...

    Comptes Rendus Biologies 335(7):463 (2012) PMID 22847013

    We used tyrosine hydroxylase immunohistochemistry (TH: the key enzyme of catecholamine biosynthesis) to evaluate the effects of prolonged dehydration on the dopaminergic system in both substancia nigra pars compacta and ventral tegmental area (SNpc and VTA), which are the main sources of dopamine in...
  8. Analysis of molecular genetic diversity of cardoon (Cynara cardunculus L.) in Tunisia.

    Comptes Rendus Biologies 335(6):389 (2012) PMID 22721560

    The objective of this study is to investigate the genetic diversity, the relationships among six Tunisian wild cardoon populations (Cynara cardunculus var. sylvestris) and a Tunisian's population of cultivated cardoon (Cynara cardunculus var. altilis DC) in seven different geographic...
  9. [Claude Bourgelat and the creation of the first veterinary schools].

    Comptes Rendus Biologies 335(5):334 (2012) PMID 22682350

    The first veterinary school in the world was created in Lyon in 1761 by an equerry, Claude Bourgelat (1712-1779), a man renowned for his skill in horsemanship and horse medicine, a man fully able to understand the issues of his time. Aware of the scope of the physiocratic movement a...
  10. Cell-derived microvesicles and antitumoral multidrug resistance.

    Comptes Rendus Biologies 335(2):103 (2012) PMID 22325563

    I suggest that MDR in tumor cells might be the consequence of a detoxification mechanism, mediated by cell-derived microvesicles. Recently published observations with tumoral human cells support this hypothesis. First, these cell-derived vesicles might impair chemotherapeutic efficiency of many stru...
