Diversity, abundance and seasonal dynamic of zooplankton community in a south-saharan reservoir (Burkina Faso).
Ouéda Adama, Guenda Wendengoudi, Kabré André T., Zongo Frédéric et Kabré Gustave Boureima
From May 2004 to April 2005, the zooplankton of the Loumbila reservoir was subject to a 14 days periodicity follow-up. This study attempt to describe the diversity, abundance and seasonal dynamic of zooplankton community in a south-saharian reservoir. Plankton community was sampled with horizontal tows of a plankton net of 100 urn mesh size. T(...)

Electrochemical synthesis of 1, 2, 4-triazol-3-thione derivatives: Anodic oxidation of N-thioamidohydrazones
I. TAPSOBA
The electrochemical oxidation of N-thioamidohydrazone, 1, was undertaken at platinum electrode in acetonitrile containing lithium perchlorate as supporting electrolyte and monitored via cyclic voltammetry and controlled potential coulometry. An overall process consisting of an irreversible two electron transfer involving, in absence or presenc(...)

Voltametry and EQCM study of copper oxidation in acidic solution in presence of chloride ions
S. Kologo; M. Eyraud; L. Bonou; F. Vacandio; Y. Massiani
Les travaux présentés dans cet article avaient pour objectif de mieux comprendre le mécanisme
d’oxydation lors de la phase de planarisation des dépôts épais du cuivre. En effet, après l’électrodéposition du
cuivre sur un substrat, la surface peut être rendue plus plane par oxydation (dissolution) des excès de dépôt.
Ce mécanisme de dissolut(...)

Etudes Phytochmiques des feuilles de Rytigynia Canthioides (Benth.) Robyns (Rubiaceae), une plante Medicinale et Alimentaire du BéninINALE ET ALIMENTAIRE UTILISEE AU BENIN
AGASSOUNON DTM, F Toukourou, C SOUZA, Mamoudou H. DICKO, AS Traoré, Gbeassor
Phytochemical studies carried out on the leaves of Rytigynia canthioides (Benth.) Robyns with regard to the content of organic and mineral substances and the presence of active principles have given satisfactory results. Our results revealed that Rytigynia canthioides contain proteins, lipids, sugar and polyphenols with the contents varying fr(...)

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(...)

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(...)

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(...)

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(...)

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(...)

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 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(...)
