Les chefferies Moosé dans la vie politique du Burkina Faso depuis 1945
Magloire Somé
Les chefs traditionnels moosé ont participé depuis la décolonisation à la vie politique du Burkina, apparaissant quelquefois comme des figures de proue de l’éveil politique, ainsi que le témoigne le rôle joué par le Mogho Naaba Sagha dans la reconstitution de la Haute-Volta. Mais ces chefs n’ont pas pu s’adapter à la situation politique nouvel(...)

Modulation of immune response in Plasmodium falciparum malaria: role of IL-12, IL-18 and TGF-beta
M Musumeci, L Malaguarnera, J Simporè, A Messina, S Musumeci
The interaction between pro- and anti-inflammatory cytokines such as interleukin 12 (IL-12), interleukin 18 (IL-18) and transforming growth factor beta (TGF-beta) plays an important role in malaria pathogenesis and outcome, modulating the immunoresponse in Plasmodium falciparum malaria. In our previous studies, we analyzed the plasmatic levels(...)

A New Route of Synthesis of 3a, 6a-Dihydro-oxazolo [5, 4-d] oxazole Derivatives
I. TAPSOBA
The electrochemical reduction of N-acylated imidates of a typical structure has been investigated by cyclic voltammetry and controlled potential electrolysis at mercury electrode in aprotic solvent. Electrodimerization occurs at the first wave and leads to the formation of 3a, 6a-dihydro-oxazolo [5, 4-d] oxazole 2 in good yields. Scheme 1.

Plasma levels of interleukin-12 (IL-12), interleukin-18 (IL-18) and transforming growth factor beta (TGF-beta) in Plasmodium falciparum malaria
Lucia Malaguarnera, Salvatore Pignatelli, Jacques Simporè, Mariano Malaguarnera, Salvatore Musumeci
The interaction between pro- and anti-inflammatory cytokines such as interleukin 12 (IL-12), interleukin 18 (IL-18) and transforming growth factor beta (TGF-beta) may play an important role in malaria pathogenesis and outcome. IL-18 cooperates with IL-12 in the IFN-gamma production by T, B, and NK cells, and synergizes with IL-12 for IFN-gamma(...)

Epidemiology of bacterial resistance in gastro-intestinal pathogens in a tropical area
Giovanni Bonfiglio, Jacques Simporè, Salvatore Pignatelli, Salvatore Musumeci, Maria Letizia Solinas
During 1999-2000 a total of 4131 faecal specimens were collected and analysed at the medical centre St. Camille at Ouagadougou. Eight hundred and twenty-six (8.0%) grew significant bacteria. Escherichia coli (35%), Salmonella spp. (15%) and Shigella spp. (10%) were most frequently isolated. A large number of E. coli strains were resistant to a(...)

Plasma levels of interleukin-18 and interleukin-12 in Plasmodium falciparum malaria
Lucia Malaguarnera, Salvatore Pignatelli, Maria Musumeci, Jacques Simporè, Salvatore Musumeci
Interleukin (IL)-18 produced primarily by mononuclear phagocytes synergizes with IL-12 for interferon-gamma production from T, B and natural killer cells. It has been also demonstrated that, in Plasmodium falciparum malaria, IL-18 could have an immunoregulatory function. The aim of this study was to detect the plasma levels of IL-12 and IL-18,(...)

Sur un problème de type elliptique parabolique non linéaire
S. Ouaro, H. Touré
We study the general equation b(u)t=a(u,φ(u)x)x+f of elliptic-parabolic type. Using the theory of evolution equation governed by an accretive operator, we establish existence and uniqueness of mild solutions to the associate Cauchy problem, under general assumptions on the data. With an additional structural condition of Alt-Luckhauss type, we(...)

Comparison of content in Phenolic compounds, polyphenol oxidases and peroxidases in grains of fifty sorghum varieties from Burkina Faso.
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-diphenola(...)

Mother-child transmission of hepatitis B virus in Ouagadougou, Burkina Faso.
D. Ilboudo, A. Sawadogo, J. Simporé
A prospective study was conducted during July-September 1999 of 299 pregnant women (aged 15-43 years; mean age 25.3 years), attending a medical centre in Ouagadougou, Burkina Faso, to determine the incidence of mother-child transmission of hepatitis B virus (HBV). The presence of HBV antigens was tested for by enzyme immunoassay. The infants o(...)

Increased levels of interleukin-12 in Plasmodium falciparum malaria: correlation with the severity of disease
Lucia Malaguarnera, Rosa Maria Imbesi, Salvatore Pignatelli, Jacques Simporè, Mariano Malaguarnera, Salvatore Musumeci
Interleukin (IL)-12, produced by mononuclear phagocytes, activates the T-helper 1 (Th1) cells and helps, as a mediator, the innate immune response to intracellular microbes. In Plasmodium falciparum infection, this proinflammatory cytokine has immunoregulatory functions with effects on the immune response to the blood stage of disease, but als(...)

Etude d’une équation elliptique associée à un problème parabolique-elliptique non linéaire
S. Ouaro, H. Touré
We study the general equation b(u)−a(u,φ(u)x)x=f of second order elliptic type, which may degenerate onto a first order equation for some value of u. We introduce for that a notion of entropy type solution for the elliptic problem. We define an L1 operator associated to the equation. We show that the operator is accretive in L1, with dense dom(...)

Zymography of Monophenolase and o-Diphenolase Activities of Polyphenol Oxidase
DICKO Mamoudou. H., HILHORST, R., GRUPPEN, H., LAANE, C., van BERKEL, W. J. H. and VORAGEN, A. G. J
A new procedure for the zymography of monophenolase and o-diphenolase activities of polyphenol oxidase (PPO), and peroxidase (POX) is proposed using a highly sensitive, chromogenic nucleophile 3-methyl-2-benzothiazolinone hydrazone (MBTH), which traps quinones. The procedure allowed the distinction between PPO isoenzymes from sorghum and mushr(...)
