Influence of malaria on the serum levels of vitamin A, zinc and calcium of children in Douala-Cameroon
Gouado Inocent, A. O. Adebiyi, Leopold G Lehman,Touridomon Issa Some, Yolande Mbouyap, Joel Bertand Pankoui Mfonkeu, Aba Richard Ejoh, Felicité Tchouanguep Mbiapo
Malaria is an endemic parasitic disease that prevails particularly in warm tropical
regions of the world. Micronutrient malnutrition such as vitamin A and iron deficiencies which
is a public health problem in Cameroon is usually highly prevalent in malaria endemic
areas. Characterizing the relationship between micronutrient status(...)

E´ tude voltame´trique des sels de styryl-2 et styryl-4 pyrylium. 1re partie
Boubie´ Guel*, Dihourahouni Tountian, Yvonne Bonzy-Coulibaly, H. Traore´, Faustin Sie´ Sib
Voltammetric study of styryl-2 and styryl-4 pyrylium salts. Part 1. The redox properties of diphenyl-2,6 styryl-4 and
diphenyl-4,6 stryl-2 pyrylium salts have been studied by means of cyclic voltammetry. These salts disclose irreversible reduction and oxidation steps that are characterised by one reduction peak and two oxidation peaks, respec(...)

Traitements insecticides et dynamique des populations de Bemisia tabaci Gennadius en culture cotonnière au Burkina Faso
Résumé Considéré dans le passé comme un ravageur secondaire, Bemisia tabaci Gennadius (Homoptera: Aleyrodidae) est devenu depuis la campagne agricole 1997-1998 un des ravageurs importants en culture cotonnière au Burkina Faso. La mise en place d'une méthode de lutte efficace contre B. tabaci passe nécessairement par une meilleure connaissance(...)

Carbon and nitrogen enhancement in Cambisols and Vertisols by Acacia spp. in eastern Burkina Faso: Relation to soil respiration and microbial biomass
S. TRAORE
The current study tested the contribution of native Acacia species of the Sudano-Sahelian zone to improving organic carbon and nitrogen level in Cambisols and Vertisols with specific focus on variation in microbial biomass (C mic), soil basal respiration (C resp) and metabolic quotient (qCO 2). The results show enrichment in total organic carb(...)

Étude des interactions intramoléculaires dans les bimétallophtalocyanines par électrochimie et par spectroélectrochimie
Karifa Bayo, Mabinty Bayo-Bangoura, Mireille Mossoyan-Deneux, Doris Lexa, Guy Venance Ouédraogo.
Nous avons préparé´ et isole´ sous forme solide une série de complexes de la phtalocyanine (Pc) de zinc : ZnPc, F8ZnPc, biZnPc, F12biZnPc. Ces composés ont été´ étudiés par voltamétrie cyclique et par spectroélectrochimie. Les résultats mettent en évidence une relation de dépendance entre la structure électronique et la nature des substituants(...)

Glucose-6-phosphate dehydrogenase deficiency and sickle cell disease in Burkina Faso
Jacques Simporé, Denise Ilboudo, Karou Damintoti, Luc Sawadogo, Maria Esposito, Scott Binet, Henri Nitiema, Paul Ouedraogo, Salvatore Pignatelli, Jean-Baptiste Nikiema
Where malaria is endemic, there is an unexpected association between haemoglobinopathies and glucose-6-phosphate dehydrogenase (G-6-PD) deficiency. Their coexistence in a patient with sickle cell disease (SCD) can lead to hemolytic anemia, hemoglobinuria, sepsis, renal failure and vaso-occlusive attacks (VOA). The aim of this research was to d(...)

In the French-speaking countries of Africa, strategies of conservation, inherited from the colonial time, exclude the bordering people in the management of the national parks plant resources. Today, policies and legislation try to reconcile forest conservation and development by associating local people. As a consequence, approaches of partici(...)

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(...)

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(...)
