In several application domains (detection systems, telecommunications, video processing, etc.) the applications deal with multidimensional data. These applications are usually embedded and subjected to real-time and resource constraints. The challenge is thus to provide efficient implementations on parallel and distributed architectures. Array-OL has been designed specifically to handle this ki...

Neher and Wettstein (1) have recently published the details of a paper chromatographic method for the separation of weakly polar steroids, with a heptane-phenyl Cellosolve solvent system. Savard (2) has described the separation of 17-ketosteroids on paper with ligroin as the mobile phase and propylene glycol as the stationary phase. Starting from the basic work of these authors, a method has be...

BACKGROUND Though on-line intermittent hemodiafiltration (OL-IHDF) is a routine therapy for chronic dialysis patients, it is not yet widespread used in critically ill patients. This study was undergone to evaluate efficiency and tolerance of OL-IHDF and to appreciate inflammatory consequences of its use in intensive care unit (ICU)-acute kidney injury (AKI) patients. METHODS In this prospecti...

Oligodendrocyte (OL) differentiation and myelin development are complex events regulated by numerous signal transduction factors. Here, we report that phosphoinositide-3 kinase enhancer L (PIKE-L) is required for OL development and myelination. PIKE-L expression is up-regulated when oligodendrocyte progenitor cells commit to differentiation. Conversely, depleting phosphoinositide-3 kinase enhan...

Six nitrogen-, sulfur- and cyclopropane-containing derivatives of cholestanol were examined as inhibitors of growth and sterol biosynthesis in the trypanosomatid protozoan Crithidia fasciculata. The concentrations of inhibitors in the culture medium required for 50% inhibition of growth were 0.32 microM for 24-thia-5 alpha,20 xi-cholestan-3 beta-ol (2), 0.009 microM for 24-methyl-24-aza-5 alpha...

BACKGROUND Oral leukoplakia (OL) is a common oral precancerous lesion. Cotton-swab cryotherapy (CSC) is commonly used for treating skin lesions but is rarely used for treating OL lesions. METHODS Sixty OL lesions were treated by CSC once every 2 weeks until complete regression (CR) of the lesion had been achieved. RESULTS CR was achieved in all 60 OL lesions after an average of 6.3 treatmen...

A polar fraction obtained from banana fruit pulp by high-vacuum distillation / solvent extraction (pentane-dichloromethane, 2 + 1) and subsequent liquid chromatography on silica gel was derivatized with isopropylisocyanate. Separation of enantiomers of heptan-2-ol and Z-4-hepten-2-ol was performed via their carbamates by means of multidimensional gas chromatography using an achiral (D B -5, col...

Streptomyces spp. have the ability to produce a wide variety of secondary metabolites that interact with the environment. This study aimed to discover antifungal volatiles from the genus Streptomyces and to determine the mechanisms of inhibition. Volatiles identified from Streptomyces spp. included three major terpenes, geosmin, caryolan-1-ol and an unknown sesquiterpene. antiSMASH and KEGG pre...
