Antimalarial activity of Sida acuta Burm. f. (Malvaceae) and Pterocarpus erinaceus Poir. (Fabaceae)
KAROU, D., Mamoudou H. DICKO, Sanon, S., Jacques, SIMPORE, Traoré, A. S
Among 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 vitro on fresh clinical isolates of Plasmodium falc(...)

RIA 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 approximately Week 8 of gestation until Week 10 postpartum ((...)

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(...)

Comparison of content in Phenolic compounds, polyphenol oxidases and peroxidases in grains of fifty sorghum varieties from Burkina Faso.
DICKO Mamoudou. H., HILHORST, R., GRUPPEN, H., TRAORE, A. S., LAANE, C., van BERKEL, W. J. H. and VORAGEN, A. G. J.
Analysis of fifty sorghum [Sorghum bicolor (L.) Moench] varieties used in Burkina
Faso showed that they have different contents of phenolic compounds, peroxidase (POX),
and polyphenol oxidase (PPO). Most of the varieties (82%) had a tannin content less than
0.25% (w/w). POX specific activity was higher than the monophenolase and o-diphenola(...)

Zymography of Monophenolase and o-Diphenolase Activities of Polyphenol Oxidase
DICKO Mamoudou. H., HILHORST, R., GRUPPEN, H., LAANE, C., van BERKEL, W. J. H. and VORAGEN, A. G. J
A new procedure for the zymography of monophenolase and o-diphenolase activities of polyphenol oxidase (PPO), and peroxidase (POX) is proposed using a highly sensitive, chromogenic nucleophile 3-methyl-2-benzothiazolinone hydrazone (MBTH), which traps quinones. The procedure allowed the distinction between PPO isoenzymes from sorghum and mushr(...)

Polysaccharide hydrolases from leaves of Boscia senegalensis
Mamoudou H. Dicko , M.J.F.Searle-van Leeuwen , R. Hilhorst , A. S. Traore , Riet Hilhorst , • Gerrit Beldman
The leaves of Boscia senegalensis are traditionally used in West Africa in cereal protection against pathogens, pharmacologic applications, and food processing. Activities of α-amylase, β-amylase, exo-(1→3, 1→4)-β-d-glucanase, and endo-(1→3)-β-d-glucanase were detected in these leaves. The endo-(1→3)-β-d-glucanase (EC3.2.1.39) was purified 203(...)
