Bromoenol lactone enhances the permeabilization of rat submandibular acinar cells by P2X7 agonists
E. KABREThe uptake of ethidium bromide by acini incubated at 37°C in the presence of 1 mM ATP increased
with time and reached after 5 min about 10% of maximal uptake measured in the presence of
digitonin … The response to ATP was dose-dependent (half-maximal concentration around
40 μM) and it...

Nucleation and growth in electrodeposition of metals on n-Si(111)
R. Krumm a, B. Guel b, C. Schmitz a, G. Staikov a,*Initial stages of electrodeposition of Tl, Cd and Cu on n-Si(111) from sulfate electrolyte solutions are studied using cyclic voltammetry and chronoamperometry. Capacitance measurements in metal ion free solutions were used to determine the flat band potential of n-Si. Results show that the...

Isolation and characterization of Desulfovibrio burkinensis sp. nov. from an African ricefield, and phylogeny of Desulfovibrio alcoholivorans
A. S. Ouattara, B. K. C. Patel, J.-L. Cayol, N. Cuzin, A. S. Traore and J.-L. GarciaA sulfate-reducing bacterium, strain HDvT (T¯type strain), was isolated from an anoxic ricefield soil. Cells were Gram-negative, non-sporulating curved rods motile by means of a single polar flagellum. Cytochrome c3 and desulfoviridin
were present. In the presence of sulfate, glycerol, 1,2-...

Incorporating batch effects in the estimation of drug stability parameters using an Arrhenius model
I T Some, P Bogaerts, R Hanus, M Hanocq, J DuboisThe nonlinear estimation of drug stability parameters (energy of activation E a and shelf-life t Y) by conventional approaches employs equations relating drug content determination C at time t and temperature T. The identification procedures lead to the determination of only one initial drug...

Study on the activation of phospholipases A 2 by purinergic agonists in rat submandibular ductal cells
E. KABREExtracellular ATP and benzoyl-ATP (Bz-ATP) increased the release of [3H] arachidonic acid ([3H] AA) from prelabeled rat submandibular gland (RSMG) ductal cells respectively two-and threefold. Both agonists also increased the release of [3H] AA from acini but at a lower level (+ 50% and+ 100%...

Activation by P2X7 Agonists of Two Phospholipases A2 (PLA2) in Ductal Cells of Rat Submandibular Gland COUPLING OF THE CALCIUM-INDEPENDENT PLA2 W...
E. KABREIsolated ductal cells of rat submandibular gland phospholipid pools were labeled with [3 H] arachidonic acid (AA). The tracer was incorporated preferentially to phosphatidylcholine (46% of the lipidic fraction). Extracellular ATP induced the release of [3 H] AA to the extracellular medium in a...

Differential sensitivity to nickel and SK&F96365 of second messengerm operated and receptormoperated calcium channels in rat submandibular ductal cells
E. KABREThe 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+...

Activation of the Na+-K+ (NH4+)-2Cl−-cotransporter from rat submandibular glands in response to VIP
E. KABREA 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...

Double épidémie de rougeole et de méningite à Bobo-Dioulasso (BF) au 1er semestre 1996: données hospitalières pédiatriques
K. NAGALOAu 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...

Study of nonspecific cation channel coupled to P2z purinergic receptors using an acid load technique
E. KABREThe 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...
