The effects of spiruline on the immune functions of HIV-infected undernourished children
Jacques Simporé, Salvatore Pignatelli, Salvatore Musumeci
Background: Malnutrition is a public health problem in the entire world, particularly in the developing countries. The effect of Spiruline supplement in the weight recovery of HIV-negative and HIV-infected undernourished children has been largely demonstrated. The aim of this study is to determine the effect of Spiruline on the immune status o(...)

Volatile components, antioxidant and antibacterial activities of Dacryodes buettneri H. J. Lam. essential oil from Gabon
Louis-Clément Obame , Jean Koudou , Jean-Claude Chalchat , Ismael Bassolé , Prosper Edou , Aboubakar S. Ouattara and Alfred S. Traore
The water-distilled oil obtained from resin of Dacryodes buettneri H.J.Lam, Burseraceae from Gabon
was examined by GC and GC/MS. The analysis led to the identification of 28 components. The essential
oil is characterized by a high proportion of terpinen-4-ol (27.33%) along with p-cymene (19%), -pinene
(13.23%), sabinene (4.40%) and isoasca(...)

Antioxidant and antimicrobial activities of Canarium schweinfurthii Engl. Essential oil from Centrafrican Republic
Louis Clément Obame , Jean Koudou , Brice S. Kumulungui , Ismael H.N. Bassolé , Prosper Edou , Aboubakar S. Ouattara and Alfred S. Traoré
The antioxidant activity of the essential oil was investigated using 2,2-diphenylpicrylhydrazyl (DPPH) radical scavenging assay and the -carotene bleaching test. Butylated hydroxytoluene (BHT) was employed as a positive control. The essential oil showed antioxidant and DPPH radical scavenging activities, and it displayed the inhibi(...)

Haemoglobin C and S role in acquired immunity against Plasmodium falciparum malaria
K. SIMPORE
A recently proposed mechanism of protection for haemoglobin C (HbC; β6Glu→ Lys) links an abnormal display of Pf EMP1, an antigen involved in malaria pathogenesis, on the surface of HbC infected erythrocytes together with the observation of reduced cytoadhesion of parasitized erythrocytes and impaired rosetting in vitro. We investigated the imp(...)

« Pacéré as the Demiurge of Orature »
André Kaboré
Not all unwritten literatures are oral literatures. They would more appropriately be referred to as “spoken literatures”, in the wider sense of literatures that use different means of communication (mouth, gestures, body movement, instruments). The dumb “speak” with signs. Pio Zirimu proposed the term “orature” to palliate the alleged contradi(...)

Réduction du PAPR par Ajout de Signal hors bande dans un contexte de Signaux Multiporteuses
Désiré Guel , Jacques Palicot , Yves Louët
Dans cet article il est question de la mise en oeuvre d'une technique de réduction du rapport puissance maximale à puissance moyenne (PAPR) pour des systèmes OFDM par ajout de signal artificiel. Nous présentons une nouvelle technique de réduction du PAPR par ajout de signal pour des signaux multiporteuses, nous étudions ensuite sa complexité a(...)

Prevalence of human herpes virus-8 and hepatitis B virus among HIV seropositive pregnant women enrolled in the Mother-to-Child HIV Transmission Prevention Program at Saint Camille Medical Centre in Burkina Faso
Denise Ilboudo, Damintoti Karou, Wendyame M. C. Nadembega, Aly Savadogo, Ouermi Djeneba, Salvatore Pignatelli, Virginio Pietra, Augustin Bere, Jacques Simporé, Alfred S. Traoré
The aims of this research are: i) to evaluate the prevalence of HHV-8, HBV and HIV among pregnant women, ii) to determine the percentage of these co-infections and iii) to estimate the frequency of the mother-to-child transmission of HIV among HBV and HHV-8 positive mothers. Thus, 379 pregnant women attending ante-natal consultation in Saint C(...)

Uniqueness of entropy solutions to nonlinear elliptic-parabolic problems.
S. Ouaro, H. Touré
We study the Cauchy problem associated with the nonlinear elliptic-parabolic equation
b(u)t−a(u,φ(u)x)x=f.
We prove an L1-contraction principle and hence the uniqueness of entropy solutions, under rather general assumptions on the data.

A Geometric Method for PAPR Reduction in a Signal Adding Context for OFDM Signals
Desire Guel; Yves Louet; Jacques Palicot
This paper presents a new technique for OFDM signal PAPR reduction by adding an artificial signal in order to restrict the envelope of the resulting signal. The algorithm is presented, some simulation results and a complexity study are given. According to these results, the new method outperforms the conclusions presented in [1]. The PAPR is r(...)

The present research was aimed to prevent mother-to-child transmission of HIV; to use RT-PCR in order to detect, 6 months after birth, infected children; and to test the antiretroviral resistance of both children and mothers in order to offer them a suitable therapy. At the Saint Camille Medical Centre, 3,127 pregnant women (aged 15-44 years)(...)
