Diagnostic de l’état de dégradation des peuplements de quatre espèces ligneuses en zone soudanienne du Burkina Faso
A. THIOMBIANO
Résumé L'aridité climatique et la pression anthropique sont à l'origine de la régression de nombreux ligneux en zone soudanienne. Afzelia africana, Bombax costatum, Boswellia dalzielii et Pterocarpus erinaceus sont des espèces multi-usages très appréciées, mais menacées de disparition dans la région est du Burkina Faso. Un diagnostic de l'état(...)

Sorghum Grain as Human Food in Africa: Relevance of Starch Content and Amylase Activities
132. DICKO Mamoudou. H., GRUPPEN, H., TRAORE, A. S.; van BERKEL, W. J. H. and VORAGEN, A. G. J
Sorghum is a staple food grain in many semi-arid and tropic areas of the world, notably in Sub-Saharan Africa because of its good adaptation to hard environments and its good yield of production. Among important biochemical components for sorghum processing are levels of starch (amylose and amylopectin) and starch depolymerizing enzymes. Curre(...)

Evaluation of the Effect of Germination on Phenolic Compounds and Antioxidant Activities in Sorghum Varieties
DICKO Mamoudou. H.,, GRUPPEN, H.; ZOUZOUHO O.C.; TRAORE, A. S.; van BERKEL, W. J. H. and VORAGEN, A. G. J.
The screening of 50 sorghum varieties showed that, on average, germination did not affect the content in total phenolic compounds but decreased the content of proanthocyanidins, 3-deoxyanthocyanidins, and flavan-4-ols. Independent of germination, there are intervarietal differences in antioxidant activities among sorghum varieties. Phenolic co(...)

Collecter des biographies contextuelles pour étudier les déterminants des comportements démographiques : l’expérience d’une enquête au Burkina Faso
SCHOUMAKER Bruno, DABIRE Hubert Bonayi et GNOUMOU THIOMBIANO Bilampoa
Depuis des dizaines d’années, de nombreux auteurs ont souligné l’importance de tenir compte des caractéristiques du contexte local pour expliquer les phénomènes démographiques. L’idée générale est que les comportements démographiques sont non seulement influencés par des facteurs individuels et au niveau du ménage, mais qu’ils dépendent égalem(...)

Phenolic Compounds and Related Enzymes as Determinants of Sorghum for Food Use
DICKO Mamoudou. H., GRUPPEN, H., TRAORE, A. S.; van BERKEL, W. J. H. and VORAGEN, A. G. J.
Phenolic compounds and related enzymes such as phenol biosynthesizing enzymes (phenylalanine ammonia lyase) and phenol catabolizing enzymes (polyphenol oxidase and peroxidase) are determinants for sorghum utilization as human food because they influence product properties during and after sorghum processing. Phenolic compounds are quality-grad(...)

Coupling of two pools of P2X7 receptors to distinct intracellular signaling pathways in rat submandibular gland
E. KABRE
The plasma membrane of cells from rat submandibular glands was isolated and extensively sonicated. The homogenate was centrifuged at high speed in a discontinuous sucrose gradient. Light fractions contained vesicles analogous to rafts: they were rich in cholesterol, they contained GM1 and caveolin-1, and P2X 7 receptors were detected in these(...)

The genus Borassus (Arecaceae) in West Africa, with a description of a new species from Burkina Faso
A. OUEDRAOGO
Abstract Borassus akeassii Bayton, Ouédraogo & Guinko sp. nov.(Arecaceae) is described as a new species from western Burkina Faso in West Africa. It has been confused with the widely distributed African species B. aethiopum and more recently with the Asian B. flabellifer. However, it is distinguished by its glaucous, green leaves with weakly a(...)

Factors predicting uptake of voluntary counselling and testing in a real‐life setting in a mother‐and‐child center in Ouagadougou, Burkina Faso
K. SIMPORE
Objective To identify factors predicting uptake of voluntary HIV counselling and testing in pregnant women. Methods All pregnant women receiving ante‐natal group health education at St Camille Medical Center, Ouagadougou, Burkina Faso from 1 May 2002 to 30 April 2004 were offered voluntary HIV counselling and testing. If they consented, the wo(...)

The positive impact of red palm oil in school meals on vitamin A status: study in Burkina Faso
Zeba Augustin, Yves Martin-Prevel, Touridomon Issa Some and Hélène Delisle
Vitamin A (VA) deficiency is widespread in sub-Saharan Africa and school-age children are a vulnerable group. In Burkina Faso, the production and consumption of red palm oil (RPO) is being promoted as a food supplement for VA. The objective of the study was to assess the impact on serum retinol of adding RPO to school lunch in two test zones o(...)

Analyse de la dynamique du couvert végétal par photographies aériennes et images Landsat dans la province de la Kompienga (Burkina Faso)
DIPAMA Jean-Marie
A la faveur de l'implantation du barrage hydroélectrique de la Kompienga en 1985 et des potentialités agro-écologiques de la zone, certaines populations des régions nord, centre nord et centre, confrontées aux péjorations climatiques récurrentes et à la dégradation des ressources naturelles, ont convergé vers l'Est du pays. En 1997, une étude(...)

Adaptative response of two varieties of cowpeas to water stress
HAMIDOU, F., Mamoudou H. DICKO ZOMBRE, G., TRAORE, A. S., and GUINKO, S
This study examined the adaptive response of the cowpea (Vigna unguiculata (L.) Walp.) to water stress at the beginning of pod formation. The regulation of carbohydrate levels, sucrose and starch in particular, was monitored in two varieties: local Gorom and KN1. In addition, the specific leaf mass and components of yield were studied. When th(...)

Impact of Phenolic Compounds and Related Enzymes in Sorghum Varieties for Resistance and Susceptibility to Biotic and Abiotic Stresses
DICKO Mamoudou. H., GRUPPEN, H., Barro, C.; TRAORE, A. S.; van BERKEL, W. J. H. and VORAGEN, A. G. J
Contents of phenolic compounds and related enzymes before and after sorghum grain germination were compared between varieties either resistant or susceptible to biotic (sooty stripe, sorghum midge, leaf anthracnose, striga, and grain molds) and abiotic lodging, drought resistance, and photoperiod sensitivity) stresses. Independent of grain ger(...)
