Differential sensitivity to nickel and SK&F96365 of second messengerm operated and receptormoperated calcium channels in rat submandibular ductal cells
E. KABRE
The intracellular concentration of calcium ([Ca 2+] i) of rat submandibular ductal cells was measured with the intracellular fluorescent dye Fura-2. Carbachol (100 μM) and ATP (1 mM) both increased the [Ca 2+] j. The late response to ATP was blocked by 0.5 mM Ni 2+. This concentration of Ni 2+ also blocked the increase of the [Ca 2+] i and the(...)

Electrodeposition of Pb on n-Si (111)
B. Rashkova, B. Guel, R.T. Pötzschke, G. Staïkov and W. J. Lorenz
Electrodeposition of lead was studied in the system n-Si(111)/Pb2+, ClO4
ÿ, H+ using cyclic voltammetry, chronoamperometry, ex situ optical microscopy and in situ scanning probe microscopy (SPM).
Comparative studies were also performed in the system HOPG(0001)/Pb2+, ClO4
ÿ, H+. No underpotential
deposition (UPD) of 2D Pb phases could be ob(...)

Activation of the Na+-K+ (NH4+)-2Cl−-cotransporter from rat submandibular glands in response to VIP
E. KABRE
A cellular suspension from rat submandibular glands was prepared with collagenase. The intracellular pH (pH i) was estimated with 2′, 7′-bis-(2-carboxy-ethyl)-5 (6)-carboxyfluorescein (BCECF). After exposure to NH 4 Cl, the pH i transiently increased (diffusion of NH 3) and then dropped (influx of NH 4+). Isoproterenol increased 2.5-fold the r(...)

Double épidémie de rougeole et de méningite à Bobo-Dioulasso (BF) au 1er semestre 1996: données hospitalières pédiatriques
K. NAGALO
Au cours du 1er semestre 1996, une double épidémie de rougeole et de méningite cérébro-spinale a éclaté au Burkina Faso:. 528 cas de rougeoles graves et 241 méningites purulentes ont été hospitalisées entre le 1er janvier et le 30 juin dans le Service de Pédiatrie du Centre Hospitalier National Sourô Sanou (CHNSS) de Bobo-Dioulasso. Les pics d(...)

Study of nonspecific cation channel coupled to P2z purinergic receptors using an acid load technique
E. KABRE
The intracellular pH (pHi) of rat submandibular cells was measured by 2', 7'-bis (carboxyethyl)-5 (6)-carboxyfluorescein (BCECF). The cells recovered from ammonium (30 mM) prepulse to their resting pHi within 10 min. Ethylisopropylamiloride (EIPA), an inhibitor of the Na+/H+ exchanger, slows the rate of pHi recovery. ATP (1 mM), in the presenc(...)

Sur une classe d'algèbres à puissances associatives
M. OUATTARA
Many papers in connection with power associativity in genetic algebras show a class of commutative power-associative algebras which are one-dimensional modulo their maximal nil ideals. In this paper we study power-associative algebras with principal and absolutely primitive idempotent and the Peirce decomposition A= A 1⊕ A 1 2⊕ A 0 of which ei(...)

"L'imaginaire et le thème du voyage dans La Voix de Gabriel Okara"
KIEMA, Alfred
A partir d'une structure du récit de la quête et d'une narration atypique, Gabriel Okara décrit le voyage du héro Okolo à la recherche des valeurs ancestrales pour redonner sens et vie au monde dominé par le matérialisme, le déni de justice et la corruption.

"The Great Carbuncle": La quête de vérité de l'humanité
PODA Michel
L’écrivain Américain du 19ème siècle Nathaniel Hawthorne est sans aucun doute un écrivain dont la fiction allie subtilité artistique et profondeur sémantique dans le regard critique qu’il porte à la marche de l’humanité. Sa nouvelle "The Great Carbuncle" nous sert ici d’illustration. L’aventure des chercheurs de la Grande Escarboucle(...)

Structure des algèbres de Bernstein
M. OUATTARA
The theory of Bernstein's algebras is revisited. Many results concerning the structure of Bernstein algebras (ideals, nilpotency and so on) are stated. For Bernstein-Jordan algebras, we give a definitive formulation of the theorem which characterizes them. Finally, we emphasize the importance of the invariant L (this ideal doesn't depend on th(...)

Dupliquée d'une algèbre et le théorème de whitehead
M. OUATTARA
The aim of this paper is to give a definitive construction of the duplicate of an algebra using divided powers. This means that no hypothesis is stated on the prime number 2. Of course, if 2 is inversible in the base ring, our construction coincides with the already known duplicate which uses symmetric powers. Moreover, we prove a Whitehead th(...)

Characterization of Anaerovibrio burkinabensis sp. nov., a Lactate- Fermenting Bacterium Isolated from Rice Field Soils
ABOUBAKAR S. OUATTARA,' ALFRED S. TRAORE,, AND JEAN-LOUIS GARCIA'"
A strictly anaerobic, gram-negative bacterium was isolated from rice field soils by using lactate as a sole
carbon and energy source. The cells were non-spore-forming, motile, curved rods. Optimal growth occurred
at 35°C and pH 6.8. No NaCl requirement was observed. Vitamins were required for growth. Our isolate,
strain B4BoT (T = type stra(...)
