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´ Macarie
A 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 substrate utilization profiles. Physiological charact(...)

Structure and emplacement model for late-orogenic Paleoproterozoic granitoids : Tenkodogo-yamba elongate pluton (eastern Burkina Faso)
Séta Naba, Martin Lompo, Pierre Debat, Jean Luc Bouchez, Didier Beziat
The Tenkodogo–Yamba (TY) elongate pluton is made of apparently isotropic biotite-bearing granites that form a continuous, 125 km long and NE trending, and 15–20 km wide, succession of granite bodies that intruded the so-called batholith of eastern Burkina Faso dominated by foliated granitoids and associated volcano-sedimentary belts.

Electrochemical synthesis of [1, 2, 4] oxadiazol-3-one derivatives: anodic oxidation of N-amidoimidates
I. TAPSOBA
Anodic 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, were identified as [1, 2, 4] oxadiazol-3-one deri(...)

Antibiotic resistance in Burkina Faso
G Bonfiglio, J Simporè, S Pignatelli, S Musumeci
Burkina Faso is one of the Subsaharan African nations. No national services for monitoring of antibiotic resistance are available, so the number of reports of resistance patterns among hospital pathogens are inconsistent. In order to evaluate antibiotic resistance, a total of 1998 valuable microrganisms were analysed during 2000 at the Medical(...)

« Oralité et production romanesque : A la recherche de traces de l’oralité moaaga dans les productions romanesques burkinabè »,
Alain Joseph Sissao
Les critiques qui abordent l’analyse du roman africain francophone sont frappés par une
certaine originalité. C’est la particularité avec laquelle les romanciers contemporains
africains expriment les faits dans la trame narrative. Une césure semble faite dans
l’écriture comme si ces derniers recherchaient dans leur quête un certain “ graal(...)

Preparation and analysis by UV-Vis of zinc phthalocyanine complexes
K. Bayo, J.C. Mossoyan , G.V. Ouedraogo
We have prepared and isolated a series of zinc phthalocyanine complexes (ZnPc, ZnPcF8, biZnPc, F12biZnPc). These compounds have been
analyzed by electronic spectrometry. The analysis of results demonstrates that the importance of intramolecular interactions in the binuclear
species depends on the nature of the peripheral substituents.
Keywo(...)

Plasma chitotriosidase activity in acute Plasmodium falciparum malaria
K. SIMPORE
Background: Chitotriosidase is a functional chitinase secreted by activated macrophages. It is encoded by a gene located on chromosome 1q31-32, whose mutations may be responsible for chitotriosidase deficiency, encountered in almost 6% of Caucasian population. Objective: This study reports firstly plasma chitotriosidase activity in African chi(...)

Les chefferies Moosé dans la vie politique du Burkina Faso depuis 1945
Magloire Somé
Les chefs traditionnels moosé ont participé depuis la décolonisation à la vie politique du Burkina, apparaissant quelquefois comme des figures de proue de l’éveil politique, ainsi que le témoigne le rôle joué par le Mogho Naaba Sagha dans la reconstitution de la Haute-Volta. Mais ces chefs n’ont pas pu s’adapter à la situation politique nouvel(...)

Modulation of immune response in Plasmodium falciparum malaria: role of IL-12, IL-18 and TGF-beta
M Musumeci, L Malaguarnera, J Simporè, A Messina, S Musumeci
The interaction between pro- and anti-inflammatory cytokines such as interleukin 12 (IL-12), interleukin 18 (IL-18) and transforming growth factor beta (TGF-beta) plays an important role in malaria pathogenesis and outcome, modulating the immunoresponse in Plasmodium falciparum malaria. In our previous studies, we analyzed the plasmatic levels(...)

A New Route of Synthesis of 3a, 6a-Dihydro-oxazolo [5, 4-d] oxazole Derivatives
I. TAPSOBA
The electrochemical reduction of N-acylated imidates of a typical structure has been investigated by cyclic voltammetry and controlled potential electrolysis at mercury electrode in aprotic solvent. Electrodimerization occurs at the first wave and leads to the formation of 3a, 6a-dihydro-oxazolo [5, 4-d] oxazole 2 in good yields. Scheme 1.
