Objective: This study evaluates the poly inosinic acid (poly I)-induced activation in the murine monocytemacrophage cell line RAW 264.7, which led to an inflammatory phenotype. Material: RAW 264.7, and WEHI 164 cell lines were used. Results: The activation process is characterized by the acquisition of a mature macrophage morphology and the production of(More)
OBJECTIVE The aim of this study was to characterize the human response to motion-cuing algorithms (MCAs) by comparing users' perception to several proposed objective indicators. BACKGROUND Other researchers have proposed several MCAs, but few improvements have been achieved lately. One of the reasons for this lack of progress is that fair comparisons(More)
An intronic variant in ANKRD55, rs6859219, is a genetic risk factor for multiple sclerosis, but the biological reasons underlying this association are unknown. We characterized the expression of ANKRD55 in human PBMCs and cell lines. Three ANKRD55 transcript variants (Ensembl isoforms 001, 005, and 007) could be detected in PBMCs and CD4(+) T cells but were(More)
Studies on plant metabolic activation with the S2 fraction from Zea mays have been developed. The 4-nitro-o-phenylenediamine (NOP) activation by S2 has been analyzed with the Ames test as a short-term assay. The NOP mutagenic potency was increased two-fold by S2, while rat liver S9 produced the contrary effect. The presence of a NADPH-generating system and(More)
Microsomal fractions from different tissues of various plants (potato, cauliflower, aubergine, avocado pear, courgette, cucumber, banana, kiwi and strawberry) were prepared and their content of cytochrome P-450 (cyt-P450) determined. A S117 fraction from Persea americana (avocado pear) presented the highest content of cyt-P450. As a consequence of these(More)
