Haemoglobin C and S in natural selection against Plasmodium falciparum malaria: a plethora or a single shared adaptive mechanism?
F. Verra, G. Bancone, P. Avellino, I. Blot, J. Simporé, D. Modiano
Conclusive evidence exists on the protective role against clinical Plasmodium falciparum malaria of Haemoglobin S (beta 6Glu-->Val) and HbC (HbC; beta 6Glu-->Lys), both occurring in sub-Saharan Africa. However, the mechanism/s of the protection exerted remain/s debated for both haemoglobin variants, HbC and HbS. Recently, an abnormal display o(...)

CADMIUM ELECTRODEPOSITION FROM AN AQUEOUS 0.1 M CdSO4 SOLUTION PART 1: ELECTROCHEMICAL AND IN SITU AFM STUDIES IN THE CASE OF n-Si(100)
Boubié GUEL
Electrochemical and in situ AFM studies of cadmium electrodeposition from an aqueous 0.1 M CdSO4 solution have been carried out in the case of (100) n-type silicon single crystal. The mechanisms related to the initial stages of the nucleation and growth mechanism of cadmium have been studied as a function of different potential steps. Within(...)

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 isoascarid(...)

beta-Endorphin concentration in colostrums of Burkinabe and Sicilian women
Maria Neve Ombra, Maria Musumeci, Jacques Simporé, Grazia Maria Palano, Salvatore Musumeci
Objective: Endorphins (EPs) present in human colostrum may be relevant for immediate postnatal fetal adaptation because this compound is involved in stress response and adaptation mechanisms. Endorphin levels in human colostrum are two-fold greater than corresponding maternal plasma levels; however, the high endorphin levels in human milk decr(...)

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(...)
