Modification in the frequency of Hb C and Hb S in Burkina Faso: an influence of migratory fluxes and improvement of patient health care
Jacques Simporé, Salvatore Pignatelli, Sergio Barlati, Salvatore Musumeci
The incidence of hemoglobinopathies (Hb C and Hb S) is relatively high in West Africa. In order to calculate the gene frequency of these hemoglobinopathies, 6619 students from 23 local schools in Ouagadougou, Burkina Faso, West Africa, and 2582 individuals living in five villages near Ouagadougou, all situated in Savanna, were studied. As expe(...)

Biological and clinical presentation of patients with hemoglobinopathies attending an urban hospital in Ouagadougou: confirmation of the modification of the balance between Hb S and Hb C in Burkina Faso
Jacques Simporé, Salvatore Pignatelli, Sergio Barlati, Salvatore Musumeci
The incidence of hemoglobinopathies (Hb C and Hb S) is relatively high in West Africa. In order to characterize the clinical phenotypes of these hemoglobinopathies 10,166 subjects were studied for suspected hemoglobinopathies at the Laboratory of the Centre Medical Saint Camille (CMSC), Ouagadougou, Burkina Faso. A high rate of Hb SC (6.49%) a(...)

Comparison of the content of phenolic compounds, polyphenol oxidase and peroxidase in grains of fifty sorghum varieties
140. DICKO Mamoudou. H., HILHORST, R., GRUPPEN, H., TRAORE, A. S., LAANE, C., van BERKEL, W. J. H. and VORAGEN, A. G. J.
Analysis of fifty sorghum [Sorghum bicolor (L.) Moench] varieties used in Burkina Faso showed that they have different contents of phenolic compounds, peroxidase (POX), and polyphenol oxidase (PPO). Most of the varieties (82%) had a tannin content less than 0.25% (w/w). POX specific activity was higher than the monophenolase and o-diphenolase(...)

Confirmation of the potential usefulness of two human beta globin pseudogene markers to estimate gene flows to and from sub-Saharan Africans
Bianca Maria Ciminelli, Fiorenza Pompei, Michela Relucenti, J. Koji Lum, Jacques Simporé, Gabriella Spedini, Cristina Martínez-Labarga, Miguel G. Pardo
Two polymorphic sites, -107 and -100 with respect to the "cap" site of the human beta globin pseudogene, recently discovered in our laboratory, turned out to have an ethnically complementary distribution. The first site is polymorphic in Europeans, North Africans, Indians (Hindu), and Oriental Asians, and monomorphic in sub-Saharan Africans. C(...)

IR and UV-Visible spectra of iron (II) phthalocyanine complexes with phosphine or phosphite
A. Zanguina, M. Bayo - Bangoura, K. Bayo, G.V. Ouédraogo.
We have prepared and studied by vibrational and electronic spectrometry of a series
of ferrophthalocyanine complexes with phosphine or phosphite axial ligands [PMe3, P(OMe)3, PPh3, P(OPh)3, PPh(OMe)3 and POH(OEt)2]. With PMe3, P(OMe)3 as ligands, only hexacoordinated
complexes are obtained but with PPh3, P(OPh)3 and POH(OEt)2 as ligands, the(...)

Les cultures africaines à l’épreuve de la colonisation
Magloire Somé
Cet article montre comment le fait colonial a par l'acculturation entraîné la dépersonnalisation des Africains, de sorte qu'à l'heure de la décolonisation, il est apparu un phénomène de résistance culturelle de la part des élites qui appellent à une renaissance par l'affirmation de la personnalité africaine. Des expériences de retour à l'authe(...)

Super-représentations faibles de superalgèbres de Malcev
Akry Koulibaly, Marie Françoise Ouedraogo
Cet article donne des propriétés de superalgèbres de Malcev sur un corps de caractéristique zéro. Nous généralisons le concept de représentation d'algèbres de Malcev aux superalgèbres de Malcev. Soit K un corps de caractéristique zéro. On sait qu'une superalgèbre est dite de Malcev si son enveloppe grassmannienne est une algèbre de Malcev. Co(...)

Supersystèmes triples de Lie associés aux superalgèbres de Malcev
Akry Koulibaly, Marie Françoise Ouedraogo
Dans cet article. Nous définissons les notions de superalgèbres triples de Lie et de super-systèmes triples de Lie. Nous montrons qu'une superalgèbre de Malcev peut être munie d'une structure de superalgèbre triple de Lie et aussi d'une structure de supersystème triple de Lie. Nous prolongeons la notion de super-représentation faible aux su(...)

Haemoglobin C protects against clinical Plasmodium falciparum malaria
Modiano D, Luoni G, Sirima BS, Simporé J, Verra F, Konaté A, Rastrelli E, Olivieri A, Calissano C, Paganotti GM, D'Urbano L, Sanou I, Sawadogo A, Modiano G, Coluzzi M
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(...)

Stability parameter estimation at ambient temperature from studies at elevated temperatures
Touridomon Issa Some, Philippe Bogaerts, Raymond Hanus, Jacques Dubois and Michel Hanocq
The determination of specific kinetic constants ki in pH–profile studies is often undertaken at ambient temperature. However, when dealing with a drug substance that is stable at ambient temperature, the pH–profile study is conducted at a chosen elevated temperature and the kinetic parameters are given at this particular elevated temperature.(...)

Christian Base Communities in Burkina Faso: Between Church and Politics
Magloire Somé
Cet article analyse l'histoire de la prise de conscience des laïcs catholiques devant la crise de l'école privée catholique. Ceux-ci créent d'abord la communauté nationale des chrétiens de Haute-Volta créant une sorte de dichotomie dans l’Église catholique au Burkina Faso. La hiérarchie démantèle cette structure à la faveur des options fondame(...)

Modulation by propranolol of the uptake of ethidium bromide by rat submandibular acinar cells exposed to a P2X7 agonist or to maitotoxin
E. KABRE
We have compared the formation of pores in rat submandibular acinar cells in response to 2′, 3′-O-(4-benzoylbenzoyl) adenosine 5′-triphosphate (Bz-ATP) and maitotoxin. Bz-ATP (100 μM) permeabilized the cells to ethidium bromide. The uptake of ethidium increased to 29±1% of maximal uptake in 10 min. dl-Propranolol (300 μM) inhibited the Bz-ATP-(...)

Polysaccharide hydrolases from leaves of Boscia senegalensis
Mamoudou H. Dicko , M.J.F.Searle-van Leeuwen , R. Hilhorst , A. S. Traore , Riet Hilhorst , • Gerrit Beldman
The leaves of Boscia senegalensis are traditionally used in West Africa in cereal protection against pathogens, pharmacologic applications, and food processing. Activities of α-amylase, β-amylase, exo-(1→3, 1→4)-β-d-glucanase, and endo-(1→3)-β-d-glucanase were detected in these leaves. The endo-(1→3)-β-d-glucanase (EC3.2.1.39) was purified 203(...)
