A Myxobolus heterospora (Baker, 1963) infection was found in 2 euryhaline tilapia species, Sarotherodon melanotheron melanotheron (Rüppel, 1853) and Tilapia zillii (Gervais, 1852), from a brackish water lake, Lake Nokoué (Benin, West Africa). The histology and ultrastructure of different levels of infection in intestinal connective tissues and wall tissues(More)
The gill myxosporean parasites of 2 euryhaline tilapias from Lake Nokoué, Sarotherodon melanotheron melanotheron (Rüppel, 1853) and Tilapia zillii (Gervais, 1852), were investigated from October 1987 to October 1989. A total of 391 S. m. melanotheron and 222 T. zillii were examined. Both of the fish species studied were infected by 3 host-specific(More)
The implication of oxidative stress as primary mechanism inducing doxorubicin (DOX) cardiotoxicity is still questionable as many in vitro studies implied supra-clinical drug doses or unreliable methodologies for reactive oxygen species (ROS) detection. The aim of this study was to clarify whether oxidative stress is involved in compliance with the(More)
Obesity is rising sharply in most industrialized countries as well in developing areas and this increase was parallel to that of diabetes mellitus. Both physiopathologic ties diseases are real health problems. This adds to a psychological impact which caused an economic and social cost of primary importance. The present work, firstly aims at evaluating the(More)
After a rapid overview of the approaches used to study cell cycle, a fluorescent digital imaging microscopy method is proposed. This method is improved by a factorial analysis relying on the evaluation of several parameters recorded on each living cell. Single lympho-blastoid living cells are labeled with three fluorescent markers: Hoechst 33342 for nuclear(More)
Laxaphycin A (laxa A) and Laxaphycin B (laxa B), cyclic peptides isolated from the terrestrial blue-green alga Anabaena laxa or the marine cyanobacterium Lyngbya majuscula have antifungal and cytotoxic activities. We used numerical videomicrofluorometry and a protocol of multiple labelling with Hoescht 33342 (nuclear DNA), Rhodamine 123 (mitochondria) and(More)
Fish culture is the best alternative to fill the gap between natural fish catches and estimated needs of populations in animal protein consumption. In West Africa, this goal required to have suitable fishes for aquaculture which are Clariidae and Tilapia. Clarias gariepinus (Clariidae) fetches a higher price than tilapias as it can be sold alive at the(More)
Mature female specimens of the catfish Clarias gariepinus originating from Ouémé River (Benin) were investigated into ovarian myxozoan parasites. Spores of Myxobolus sp. (Myxozoa: Myxosporea) were found encrusted in the whitish color oocytes which present fat dot aspect in the gonads. The pathological investigation by electron microscopy revealed that(More)
We investigate the relative importance of the different mechanisms of Adriamycin, an anthracycline, and their interrelations, in particular the link between cell cycle arrest, cell death, and generation of reactive oxygen species (ROS) that is suspected to be the origin of cardiotoxic side-effects. We introduced a lifetime fluorescence based technology and(More)
Improving the neuronal yield from in vitro cultivated neural progenitor cells (NPCs) is an essential challenge in transplantation therapy in neurological disorders. In this regard, Ascorbic acid (AA) is widely used to expand neurogenesis from NPCs in cultures although the mechanisms of its action remain unclear. Neurogenesis from NPCs is regulated by the(More)
