From spectral clear sky emissivity to total clear sky emissivity
D. BATHIEBO
From standard and observed atmospheric profiles a simple model to compute the spectral sky emissivity has been built, and compared with Lowtran-6 code calculations. In the present paper, it is analytically integrated. The relations expressing the total emissivity point out a small effect of hygrometry. They are discussed and compared with thos(...)

Expressions for computing the radiative cooling flux from the sky in different climates
D. BATHIEBO
Sky radiation affects numerous systems but is often under estimated. This paper is especially oriented towards its determination in hot countries for cooling purposes. It includes expressions for clear weather conditions and shows some properties and the power of the flux according to the climates. Observations in Kuwait and in the Ivory Coast(...)

Bazoin Sylvain Raoul Bazie, Adjima Bougma, Aminata Sere, Judicael Thomas Ouilly, Hassane Sangare, Elie Kabre, Aly Savadogo, Djidjoho Joseph Hounhouigan, Marie-Louise Scippo, Imael Henri Nestor Bassole
The nutritional status of meat is tarnished by its association with the induced cooking contaminants. The aim of this study was to assess the heterocyclic aromatic amines profile and contents in processed chicken in Burkina Faso. Eight polar and apolar heterocyclic aromatic amines (HAAs) including 2-mino-3-methylimidazo[4,5-f]quinolone (IQ), 3(...)

A 24-bp duplication in exon 10 of human chitotriosidase gene from the sub-Saharan to the Mediterranean area: role of parasitic diseases and environmental conditio...
K. SIMPORE
Human chitotriosidase (Chit) is a member of the chitinase family and it is synthesized by activated macrophages. Recently, a genetic polymorphism was found to be responsible for the common deficiency in Chit activity, frequently encountered in different populations. We analyzed the Chit gene in some ethnic groups from the Mediterranean and Afr(...)

Etude comparée des effets anti-hépatotoxiques d’extraits d’Argemone mexicana L.(Papaveraceae), une plante utilisée dans le traitement traditionnel de la jaunisse...
E. KABRE
Argemone mexicana L.(Papaveraceae) fait l'objet de nombreuses indications thérapeutiques en médecine traditionnelle dans la région des Cascades au Burkina Faso. Dans une étude préliminaire de 2006, il a été mis en évidence une activité anti-hépatotoxique du décocté aqueux lyophilisé des feuilles chez le rat Wistar préalablement ictérisé par un(...)

Floristic and dendrometric analysis of woodlands in the Sudano-Guinean zone: a case study of Belléfoungou forest reserve in Benin
A. OUEDRAOGO
A floristic and dendrometric analysis was carried out using 15 square plots of 1 ha each in the Belléfoungou forest reserve, located in the Sudano-Guinean zone of Benin. Species and diameter at breast height of trees were recorded. Multidimensional scaling and importance value index of species were used to identify vegetation types in the rese(...)

In vitro assay of potential antifungal and antibacterial activities of extracts of Borassus aethiopum Mart
E. KABRE
The anti-inflammatory, antipyretic, and pro-apoptotic properties of extracts of Borassus aethiopum have been reported in the literature. In this study, we investigated the antifungal and antibacterial properties of Borassus aethiopum male inflorescences extracts. The antifungal and antibacterial activity was studied by agar well diffusion meth(...)

Tree leaves in the diet of free-ranging ruminants in three areas of Burkina Faso
B. NACOULMA
A study was undertaken to document the botanical composition of free ranging cattle and small ruminants in three separate areas of Burkina Faso, as the first step towards improved use and management of trees. Faecal samples were taken from cattle at three sites and from small ruminants at one site throughout a year and plant particles in the f(...)

Huge right atrial myxoma revealed by right heart failure
N. YAMEOGO
Right atrial myxoma is a heart benignant tumor characterized by an important clinical polymorphism. We report a case of a 30-year-old female with a diagnosis of a big right atrial myxoma. The diagnosis has been done by transthoracic echocardiography which showed an important tumorous mass in the right atrium. It was moving, inhomogeneous and t(...)

Population structure of three woody species in four ethnic domains of the sub‐sahel of Burkina Faso
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 species(...)

Do floristic composition, plant species abundance and vegetation structure in Sudanian wetlands vary according to conservation status?
B. NACOULMA
In Sahel, wetlands are particularly endangered hence practical knowledge for their sustainable management is needed. The aim of this study was to compare plant community structure between protected and unprotected wetland bank stands in eastern Burkina Faso. Phytosociological and dendrometrical parameters were carrying out in adult trees, seed(...)

Haemoglobin C protects against clinical Plasmodium falciparum malaria
K. SIMPORE
Abstract Haemoglobin C (HbC; β6Glu→ Lys) is common in malarious areas of West Africa, especially in Burkina Faso 1, 2. Conclusive evidence exists on the protective role against severe malaria of haemoglobin S (HbS; β6Glu→ Val) heterozygosity 3, whereas conflicting results for the HbC trait have been reported 4, 5, 6, 7, 8, 9, 10 and no epidemi(...)
