Prévalence du déficit en Glucose-6-Phosphate Déshydrogénase (G6PD) et de la Drépanocytose chez les nouveau-nés à Ouagadougou (Burkina Faso)
E. Kafando, M. Sawadogo, E. Youl, E. Kabré, E. NacoulmaLe déficit en G6PD et la drépanocytose sont deux pathologies héréditaires du globule rouge responsables d'anémie hémolytiques. ces deux affections souvent associées sont fréquentes dans la population africaine où elles se superposent aux zones d'endémie palustre. l'objectif de notre...

Chemical composition and antibacterial activities of the essential oils of Lippia chevalieri and Lippia multiflora from Burkina Faso
I.H.N. Bassole , A.S. Ouattara , R. Nebie , C.A.T. Ouattara , Z.I. Kabore , S.A. TraoreThe chemical composition of the essential oils of Lippia chevalieri and Lippia multiflora obtained from the air-dried leaves by hydrodistillation were analysed using GC and GC–MS. L. chevalieri and L. multiflora belonged to thymol/p-cymene/2-phenyl ethylpropionate and thymol/p-cymene/thymyl...

Les implications écologiques du barrages de la Kompienga sur le bassin versant
DIPAMA Jean-MariePour réduire sa consommation de produits pétroliers et améliorer son potentiel énergétique, le Burkina Faso a entrepris, en 1985, la construction d'un barrage hydroélectrique sur la Kompienga. Le bassin versant couvre 5 945 km² et la végétation y est du type savanicole, avec des forêts...

Antimalarial activity of Sida acuta Burm. f. (Malvaceae) and Pterocarpus erinaceus Poir. (Fabaceae)
KAROU, D., Mamoudou H. DICKO, Sanon, S., Jacques, SIMPORE, Traoré, A. SAmong strategies to combat malaria, the search for new antimalarial drugs appears to be a priority. Sheering for new antimalarial activities, four plants of the traditional medicine of Burkina Faso: Combretum micranthum, Khaya senegalensis, Pterocarpus erinaceus and Sida acuta, were tested in...

Pregnancy-associated glycoprotein concentrations during pregnancy and the postpartum period in Azawak Zebu cattle
Moussa Zongo, Were Pitala, Hamidou Boly, Laya Sawadogo, Jean-FrancËois Beckers , Noelita Melo de Sousa, Jose Ricardo de Figueiredo, Paulo Bayard Dias GoncËalves, Bouchra El Amiri, Zsolt PereÁnyi, Jean-FrancËois BeckersRIA systems were developed and used to measure pregnancy-associated Glycoprotein (PAG) concentrations during gestation and the postpartum period in Azawak Zebu cows. Twelve females were palpated per rectum and diagnosed as pregnant. Blood samples were taken at 5±10-day intervals from...

Numerical study of natural convection drying of coffee grains contained in a vertical channel with constant heat flux on walls
D. BATHIEBOWe present a numerical study of the drying by natural convection of coffee grains contained between two vertical walls subjected to a uniform heat flux. The coffee grains bed is assumed to be in a porous medium, heat and mass transfers which are described by the classical natural convection...

Directional spectral emissivities of clear skies
D. BATHIEBOFrom the total spectral emissivities determined for clear skies in a preceding paper their directional values are obtained. The Bliss formulation still used for this doing is justified. The results point out the inefficiency of a large band around the horizon for cooling purposes. As an...

Bosea minatitlanensis sp. nov., a strictly aerobic bacterium isolated from an anaerobic digester
Aboubakar S. Ouattara, Essokazi A. Assih, Sebastien Thierry, Jean-Luc Cayol, Marc Labat, Oscar Monroy and Herve´ MacarieA strictly aerobic, mesophilic bacterium, strain AMX 51T, was isolated from anaerobic digester sludge. Cells were Gram-negative, motile, non-sporulating, straight to curved rods with one polar flagellum. The isolate had phenotypic traits of the genus Bosea, including cellular fatty acid and...

Electrochemical synthesis of [1, 2, 4] oxadiazol-3-one derivatives: anodic oxidation of N-amidoimidates
I. TAPSOBAAnodic oxidation of N-amidoimidates was performed in acetonitrile+ lithium perchlorate as the electrolyte solution at platinum using controlled potentials. The products, isolated in good yield after oxidation of the amide group followed by deprotonation and intramolecular cyclization reactions,...
