An interesting new subgenus of Scorpiops Peters, 1861 from North Vietnam (Scorpiones: Euscorpiidae: Scorpiopinae)
Comptes Rendus Biologies (2013)Scorpiops (Vietscorpiops) dentidactylus subgen. n. et sp. n., belonging to the family Euscorpiidae Laurie, 1896, is described on the basis of single male collected in Dien Bien Province, Muong Nhe District, Nam Vi Commune, in a limestone formation covered by rainforest, in the extreme Nort...
Production of a high level of laccase by submerged fermentation at 120-L scale of Cerrena unicolor C-139 grown on wheat bran.
Submerged fermentation in a stirred bioreactor of the white rot fungus Cerrena unicolor C-139 was done at a 120-L scale in the presence of wheat bran as a cheap lignocellulosic substrate for fungus growth and laccase production. Enzyme monitoring showed that laccase production started after 2days of...
Integrated options for the management of black root rot of strawberry caused by Rhizoctonia solani Kuhn.
An investigation was made to manage strawberry black root rot caused by Rhizoctonia solani (R. solani) through the integration of Trichoderma harzianum (T. harzianum) isolate STA7, mustard oil cake and Provax 200. A series of preliminary experiments were conducted to select a virulent isolate of R. ...
Parnassius apollo last-instar larvae development prediction by analysis of weather condition as a tool in the species' conservation.
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...
Sex expression and reproductive biology in a tree species, Fraxinus excelsior L.
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...
Relevance of blood groups in transfusion of sickle cell disease patients.
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...
Post-transfusional iron overload in the haemoglobinopathies.
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...
Spermiogenesis and the spermatozoon ultrastructure of Robphildollfusium fractum (Digenea: Gyliauchenidae), an intestinal parasite of Sarpa s...
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...
[The fight against epizootics in the 21st Century].
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...
Obesity, insulin resistance and diabetes in the sand rat exposed to a hypercaloric diet; possible protective effect for IL1-β.
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...
