Thermal degradation of polyethylene bags and millet stalks : influence of the temperature and the local concentration of oxygen on the conversion rate of carbon
Salifou K. Ouiminga, Thomas Rogaume, Tizane Daho, Franck Richard and Jean Koulidiati
This paper concerns the influence of temperature and local concentration of oxygen on the conversion efficiency of
carbon into CO, CO2, CH4, C3H8, C2H4, C2H2, C2H6, C6H6, during the thermal degradation of plastic bags and millet
stalks. The experimental device used is the tubular kiln, coupled to an analyzer Fourier Transform Infrared (FTIR)(...)

Collision-induced dissociation of flavonoid 7-O-diglycoside cations: elucidation of important structural motifs by selection of the cationizing reaction
Ousmane Ilboudo, Issa Tapsoba, Yvonne L Bonzi-Coulibaly, Pascal Gerbaux
Flavonoids are ubiquitous molecules in nature and are found in almost all plants, including fruits and vegetables. Although flavonoids are structurally similar, subtle differences in their structures lead to important changes in their biological activities. Over years, mass spectrometry has become an ideal tool for the characterization of thos(...)

Effectiveness of the Regular Implementation of the Mother to Child Transmission Plus (MTCT-Plus) Program in Burkina Faso, West Africa
Fabio Buelli, Virginio Pietra, Richard Fabian Schumacher, Jacques Simpore, Salvatore Pignatelli, Francesco Castelli and the ESTHER-Brescia Study Group
Since the 90s, many developing countries have introduced health strategies aimed at reducing Mother-to-Child transmission rate of HIV. These strategies (PMTCT – Prevention of Mother-to-Child Transmission) are based on (i) adequate counselling for HIV voluntary testing during antenatal care visits, (ii) single dose or a short antiretroviral the(...)

Hemoglobins S and C interfere with actin remodeling in Plasmodium falciparum-infected erythrocytes
Marek Cyrklaff, Cecilia P. Sanchez, Nicole Kilian, Cyrille Bisseye, Jacques Simporé, Friedrich Frischknecht, Michael Lanzer
The hemoglobins S and C protect carriers from severe Plasmodium falciparum malaria. Here, we found that these hemoglobinopathies affected the trafficking system that directs parasite-encoded proteins to the surface of infected erythrocytes. Cryoelectron tomography revealed that the parasite generated a host-derived actin cytoskeleton within th(...)

Impacts of land-use on West African savanna vegetation: a comparison between protected and communal area in Burkina Faso
A. THIOMBIANO
Biodiversity matters in many aspects for human well-being by providing timber and non-timber products. The most important ecosystems providing these products in West Africa are savannas. In the context of land-use changes, there is an urgent need to understand the impact of land-use on savanna vegetation and biodiversity. This study assesses t(...)

Antioxidant and anti-inflammatory effects of Scoparia dulcis L.
M. KIENDREBEOGO
Different extracts were obtained from Scoparia dulcis L.(Scrophulariaceae) by successive extraction with hexane, chloroform, and methanol. These extracts exhibited significant antioxidant capacity in various antioxidant models mediated (xantine oxidase and lipoxygenase) or not mediated (2, 2-diphenyl-picrylhydrazyl, ferric-reducing antioxidant(...)

Population structure of three woody species in four ethnic domains of the sub‐sahel of Burkina Faso
T. K. Sop, J. Oldeland, U. Schmiedel, I. Ouedraogo, A. Thiombiano
In developing countries many people depend on woody resources for their livelihoods. Monitoring human impact on the populations of socio-economically important species is therefore important for the conservation of vulnerable plants.
In order to assess and compare the population structure and regeneration patterns of three multipurpose spec(...)

Oxidative stress due to abnormal production of reactive oxygen species has been implicated in the nephrotoxicity induced by gentamicin. The nephroprotective effect of aqueous-ethanolic extract of Moringa oleifera leaves (150 and 300 mg/kg) was evaluated against gentamicin-induced (80 mg/kg) renal injury in rabbits. Serum urea and creatinine le(...)
