Regeneration of five Combretaceae species along a latitudinal gradient in Sahelo-Sudanian zone of Burkina Faso
A. THIOMBIANO
Seedling density and the regeneration mechanisms of five tree species, Anogeissus leiocarpa, Combretum aculeatum, Combretum micranthum, Combretum nigricans, and Pteleopsis suberosa were investigated in relation to latitudinal gradient across the Sahelo-Sudanian zone of West Africa.

Une méthode mécanique pour mesurer la pression de vapeur d’équilibre de l’eau dans un milieu complexe
Samuel Ouoba, Bruno Cousin, Fabien Cherblanc, Jean-Claude Bénet
Cette Note présente une nouvelle méthode pour déterminer la pression de vapeur d’équilibre de l’eau dans un milieu complexe. On entend par «milieu complexe » un milieu où des interactions physico-chimiques modifient les propriétés thermodynamiques de l’eau notamment son activité et sa pression de vapeur d’équilibre. La méthode présentée consis(...)

Antimicrobial and antioxidant activities of essential oil and methanol extract of Jasminum sambac from Djibouti
Fatouma Abdoul-Latif , Prosper Edou , François Eba , Nabil Mohamed , Adwa Ali , Samatar Djama , Louis-Clément Obame , Ismael Bassolé 5 and Mamoudou Dicko
The essential oil was subjected to screening for their possible antioxidant activity by two
complementary test systems, namely DPPH free radical scavenging and -carotene-linoleic acid
assays. Butylated hydroxytoluene (BHT) was used as positive control in both test systems. In the DPPH
test system, the IC(...)

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(...)

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(...)

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(...)

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(...)

Development of an in vitro Endotoxin Test for Monoolein–Water Liquid Crystalline Gel for Use as an Implant
Moustapha Ouédraogo, Rasmané Semdé, Touridomon Issa Some, Rasmata Ouédraogo, Viviane Henschel, Brigitte Evrard, Jacques Dubois, Karim Amighi and Innocent P Guissou
Purpose: Drugs that are administered by parenteral route must be apyrogenic. The aim of this study was to develop an in vitro endotoxin test for liquid crystalline gels for use as implants, using a monoolein–water liquid crystalline gel as a model. Methods: The gel-clot technique was used. The gel was dissolved first in isopropyl myristate, an(...)

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
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.
