As part of ongoing research on the chemical composition and the antimicrobial properties of Burkinabe
plants essential oils alone and in combination, essential oils (EOs) from leaves of Cymbopogon citratus and
Cymbopogon giganteus from Burkina Faso were analyzed by GC–FID and GC–MS. Five constituents, which
accounted for 96.3% of the oil, w(...)

An engineered Plasmodium falciparum C-terminal 19-kilodalton merozoite surface protein 1 vaccine candidate induces high levels of interferon-gamma production associated with cellular immune responses to specific peptide sequences in Gambian adults naturally exposed to malaria
C Bisseye, L M Yindom, J Simporé, W D Morgan, A A Holder, J Ismaili
The 19-kDa C-terminal region of merozoite surface protein 1 (MSP1(19)), a major blood stage malaria vaccine candidate, is the target of cellular and humoral immune responses in humans naturally infected with Plasmodium falciparum. We have previously described engineered variants of this protein, designed to be better vaccine candidates, but th(...)

Homozygous Deletion of an EGR2 Enhancer in Congenital Amyelinating Neuropathy
Benoit Funalot, Piotr Topilko, Maria Antonia Ramos Arroyo, Abdelaziz Sefiani, E. Tessa Hedley-Whyte, Maria E. Yoldi, Laurence Richard, Estelle Touraille, Mathieu Laurichesse, Emmanuel Khalifa, Jasmine Chauzeix, Adama Ouedraogo, Didier Cros, Corinne Magdelaine, Franck G. Sturtz, J. Andoni Urtizberea, Patrick Charnay, Federico Garcia Bragado and Jean-Michel Vallat
The transcription factor EGR2 is expressed in Schwann cells, where it controls peripheral nerve myelination. Mutations of EGR2 have been found in patients with congenital hypomyelinating neuropathy or Charcot–Marie–Tooth disease type 1D. In a patient with congenital amyelinating neuropathy, we observed pathological abnormalities recapitulatin(...)

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(...)

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(...)

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(...)

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(...)
