Entropy solutions of a stationary problem associated to a nonlinear parabolic strongly degenerate problem in one space dimension.
S. Ouaro
We study a nonlinear elliptic degenerate equation with the form: b(u)−a(u,φ(u)x)x=f which is associated to the elliptic-parabolic-hyperbolic equation of the form: b(u)t−a(u,φ(u)x)x=f. We prove in this work without Alt and Luckhaus structure condition existence and uniqueness of entropy solutions of the associated Dirichlet problem. We also def(...)

Network of sexual contacts and sexually transmitted HIV infection in Burkina Faso
Vito Latora, André Nyamba, Jacques Simpore, Bahiré Sylvette, Sandwidi Diane, Bukiki Sylvére, Salvatore Musumeci
Two thirds of the people who have been infected by human immunodeficiency virus (HIV) in the world live in Sub-Saharan African countries. The results of a study measuring the degree distribution of the network of sexual contacts in Burkina Faso are described. Such a network is responsible for the spread of sexually transmitted diseases, and in(...)

Toxoplasma gondii, HCV, and HBV seroprevalence and co‐infection among HIV‐positive and‐negative pregnant women in Burkina Faso
Jacques Simpore, Aly Savadogo, Denise Ilboudo, Marie Christelle Nadambega, Maria Esposito, Justine Yara, Salvatore Pignatelli, Virginio Pietra, Salvatore Musumeci
Toxoplasma gondii (T. gondii) infections can cause serious complications in HIV‐infected pregnant women, leading to miscarriage, stillbirth, birth defects (eg, mental retardation, blindness, epilepsy etc.) and could favor or enhance the mother‐to‐child transmission of HCV, HBV, and HIV vertical transmission. From May 20, 2004 to August 3, 2005(...)

L’esthétique de la poésie senghorienne, les fondements d’une esthétique négroafricaine
Alain Joseph Sissao
Senghor est connu comme l’homme de culture qui a basé son esthétique sur la culture africaine. Pour ce faire, il a forgé les outils conceptuels qui devaient lui servir de
tremplin pour nourrir ses textes poétiques. Il s’agira d’explorer les éléments qui montrent que les textes de Senghor obéissent à une esthétique africaine dont la négritude(...)

[Prevalence of Hepatitis C virus infection in pregnant women and mother-child transmission in Ouagadougou, Burkina Faso]
A K Serme, P D Ilboudo, A Samandoulgou, J Simpore, A Bougouma, A R Sombie
The aim of our study was to estimate the prevalence of Hepatitis C virus (HCV) among pregnant women and the rate of mother-child transmission. Over one month (April 26 to May 25, 2002) blood samples of 200 pregnant women who gave birth at the maternity of the university hospital and Gounguin center medical of Ouagadougou were tested for anti-H(...)

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(...)

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(...)

Caractères magnétiques, fabriques et contexte géodynamique des granites du Burkina Faso Oriental : Plutons de Tenkodogo-Yamba, de Kouaré et de Nanéni
Naba S., Vegas N., Bouchez J.L., Siqueira R. et Lompo M
Les granites à biotite d'âge paléoprotérozoïque de l'Est du Burkina Faso, sont étudiés pour leur susceptibilité magnétique, leur aimantation rémanente naturelle et leurs fabriques magnétiques. L'aimantation rémanente naturelle, souvent supérieure à l'aimantation induite sous champ terrestre, justifie que l'on mesure ces propriétés pour interpr(...)

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(...)

One thousand three hundred and twenty-eight pregnant women with less than 32 weeks of amenorrhea received voluntary counseling and testing at Saint Camille Medical Center from May 1, 2002 to December 30, 2004. Following informed consent and pre-test counseling, HIV screening was performed in 1,202 women. According to the prevention protocol, H(...)
