Abstract: The present invention relates to the field of epidermal repair. More particularly, the invention concerns the use of a molecule able to inhibit a heteromeric receptor comprising OSMR? as a subunit, for the preparation of a composition for inhibiting the expression of inflammatory factors by the keratinocytes. In particular, the invention concerns the use of antagonists and/or expression inhibitors of OSM, IL-17, TNF?, IL-31, IFN-?, and/or the OSMR? subunit, for the preparation of cosmetic or dermatologic compositions, especially for treating inflammatory skin diseases. Methods for obtaining in vitro or animal models of skin inflammation diseases are also disclosed. These models can be used for screening molecules to find new drugs to prevent or treat psoriasis and other dermatitis.

Abstract: The present invention relates to a method and apparatus for deconvolving a noisy measured signal obtained from a sensor device (100), said noisy measured signal (y(t)) being the sum of the convolution product (x(t)N(t)) of an input signal (x(t)) of the sensor device, representative of a feature of physical quantity, by a convolution kernel (N(t)) defined by the response function of the sensor device (100) and a noise which interfere with the measure. The method is characterised in that said method comprises an estimate computation step (400) in the course of which a minimal estimate (xmin(t)N(t)) of the convolution product of the input signal by the convolution kernel of the sensor device is computed in order that said minimal estimate stays below the noisy measured signal (y(t)) and has at least one point in common with the noisy measured signal (y(t)).
Abstract: The present invention relates to a non-invasive method for assessing liver fibrosis progression in an individual, said method comprising the steps of calculating the ratio of fibrosis level to cause duration and to a non-invasive method for assessing liver fibrosis progression in an individual, said method comprising the steps of measuring, at two different times t1 and t2, the fibrosis levels FL (t1) and FL (t2) and calculating the ratio FL (t2)?FL (t1) to (t2?t1) and to a non-invasive method for assessing if an individual is a slow, medium or fast fibroser.
