Regulation by CRAMP of the responses of murine peritoneal macrophages to extracellular ATP
E. KABRE
Peritoneal macrophages were isolated from wild type (WT) mice and from mice invalidated for the P2X7 receptor (KO) which had been pretreated with thioglycolate. In cells from WT mice, 1 mM ATP increased the intracellular concentration of calcium ([Ca2+] i), the uptake of ethidium bromide, the production of reactive oxygen species (ROS), the se(...)

Etude morphologique comparative de cinq variétés de gombo [Abelmoschus esculentus (L.) Moench] soumises à un stress hydrique
Nana Rasmata, Tamini Zoumbiessé, Sawadogo Mahamadou et Somé Pépin Patrice
L’impact d’un stress hydrique intervenu au stade végétatif et au stade floraison sur la croissance de cinq variétés de gombo a été étudié sous serre. L’application des différents stress hydriques a consisté à suspendre l’arrosage des plantes, respectivement du 32ème au 45ème jour après semis et à partir de 50% des plantes en fleur et ceci pend(...)

Tailoring the Hydrophobic Character of Mesoporous Silica by Silylation for VOC Removal
Isabelle Batonneau-Gener, Arsène Yonli, Adeline Trouvé, Samuel Mignard, Matteo Guidotti, Maila Sgobba
MCM-41 and non-ordered mesoporous silica were modified using hexamethyl-disilazane (HMDS). The hydrophobic and hydrophilic properties of grafted materials were studied and compared to a purely all silica BEA zeolite by using competitive and noncompetitive water toluene adsorption. A linear correlation between the silylation degree and the hydr(...)

Antimicrobial and antioxidant activities of essential oil and methanol extract of Jasminum sambac from Djibouti
127. ABDOUL-LATIF Fatouma, P Edou, F Eba, N Mohamed, A Ali, S Djama, LC Obame, INHl Bassolé, Mamoudou H. DICKO
The essential oil of jasminum sambac from Djibouti was subjected to screening for their possible antioxidant activity by two complementary test systems, namely DPPH free radical scavenging and beta-carotene-linoleic acid assays. Butylated hydroxytoluene (BHT) was used as positive control in both test systems. In the DPPH test system, the IC50(...)

Structural stability for variable exponent elliptic problems. I: The p(x)-Laplacian kind problems
B. Andreianov, M. Bendahmane, S. Ouaro
We study the structural stability (i.e., the continuous dependence on coefficients) of solutions of the elliptic problems under the form
b(un)−divan(x,∇un)=fn.
The equation is set in a bounded domain Ω of ℝN and supplied with the homogeneous Dirichlet boundary condition on ∂Ω. Here b is a non-decreasing function on ℝ, and (an(x,ξ))n is a f(...)

Composition and Antimicrobial Activities of Lippia multiflora Moldenke, Mentha x piperita L. and Ocimum basilicum L. Essential Oils and Their Major Monoterpene Alcohols Alone and in Combination
126. BASSOLÉ IHN, Lamien-Meda A, Bayala B, Tirogo S, Chlodwig Franz, Johannes Novak, Roger Charles Nebié and Mamoudou H. DICKO (
Essential oils from leaves of Lippia multiflora, Mentha x piperita and Ocimum basilicum from Burkina Faso were analysed by GC–FID and GC–MS. Major components were p-cymene, thymol, β-caryophyllene, carvacrol and carvone for L. multiflora, menthol and iso-menthone for M. x piperita and, linalool and eugenol for O. basilicum. The essential oils(...)

Correlative and comparative characterization of main ion concentrations in laterite groundwater in semi-arid northern Burkina Faso
Julien Nikiema, Mario Schirmer, Walter Gläßer, Ronald Krieg
About 24 samples from hand-dug wells and boreholes were used to characterize concentrations of the main inorganic ions in a laterite environment under semi-arid climatic conditions in Tikaré, northern Burkina Faso. It was found that the most represented groundwater anion in groundwater was HCO3− with average levels of 49.1 mg/L in the dry seas(...)

De la réconciliation terrestre. Essai sur la citoyenneté réhabilitée
Koné Cyrille B
La réconciliation est-elle un mode de règlement des conflits, fondé sur le consensus ou est-ce plutôt une sorte de "bouée de sauvetage" pour les pouvoirs en place, un instrument de mise au pas des contestataires? Face à la multiplicité des scènes de réconciliation un peu partout dans le monde, l'étude tente de clarifier la notion pour en défin(...)

Structural stability for variable exponent elliptic problems. II: The p(u)-Laplacian and coupled problems
B. Andreianov, M. Bendahmane, S. Ouaro
We study well-posedness for elliptic problems under the form
b(u)−div 𝔞(x,u,∇u)=f,
where 𝔞 satisfies the classical Leray-Lions assumptions with an exponent p that may depend both on the space variable x and on the unknown solution u. A prototype case is the equation u−div (|∇u|p(u)−2∇u)=f.
We have to assume that infx∈Ω⎯⎯⎯⎯⎯,z∈ℝp(x,z) is gre(...)

Identification of catechin as one of the flavonoids from Combretum albiflorum bark extract that reduces the production of quorum-sensing-controlled virulence factors in Pseudomonas aeruginosa PAO1
M. KIENDREBEOGO
Quorum-sensing (QS) regulates the production of key virulence factors in Pseudomonas aeruginosa and other important pathogenic bacteria. In this report, extracts of leaves and bark of Combretum albiflorum (Tul.) Jongkind (Combretaceae) were found to quench the production of QS-dependent factors in P. aeruginosa PAO1. Chromatographic fractionat(...)
