Abstract: The present disclosure concerns a cell or tissue culture system comprising a solid support for the culture of adherent cells or adherent tissues and a plurality of cationic dendrimers associated to the surface of the solid support. Each cationic dendrimer includes one or more functional amine group. The cationic dendrimer is protonated at physiological pH. The cell or tissue culture system can be used for the culture of adherent cells or tissues and be used for the differentiation of stem cells.

Abstract: A comfort liner provided with a wedging element made of foam having thermoplastic qualities rendering it capable of being adjusted and/or adapted, after being heated at its thermoforming temperature, to the specific volume of the user's foot. The liner in its entirety is preformed at an initial fitting volume corresponding to a standard of a given size, and its wedging element, constituted of foam formed from at least one thermoplastic material, is thermocompressed and micro-perforated. The micro-perforations confer to the wedging element a certain flexibility and elastic compressibility, as well as a certain permeability rendering it sufficiently comfortable to be used as such, and adapted to be easily thermoformed by reheating, due to the rapid and in-depth diffusion of the heat across the micro-perforations.

Abstract: A comfort liner for a ski boat provided with a wedging element made of foam having thermoplastic qualities rendering it adapted to be adjusted and/or adapted, after being heated at its thermoforming temperature, to the specific volume of the foot of the skier, and a ski boot incorporating such liner. The liner in its entirety is preformed to an initial foot fitting volume corresponding to the standard of a given size, and its wedging element, constituted by a foam formed from at least one thermoplastic material, is thermocompressed and micro-perforated. The micro-perforations confer to the wedging element a certain flexibility and elastic compressibility, as well as a certain permeability rendering it sufficiently comfortable to be used as such for skiing, and adapted to be easily thermoformed by reheating, by virtue of the rapid and in-depth diffusion of the heat across the micro-perforations.

Abstract: The invention relates to a ski boot in which the shell base includes a single abutment, adjustable in position, with which cooperates the upper for its rearward support and its retention in front inflexion by means of the ends of an oblong slot and a movable element. This movable element, mounted on the upper in combination with the single abutment, provides, at will, the latching of the upper by adjustment under the abutment, or the unlatching of the upper in forward flexion alone, and along a predetermined amplitude by retraction of the abutment.

Abstract: An interface device between a ski (1) and bindings (3, 4) designed to hold in place the ends of a ski boot on a ski. The device comprises a longilinear plate (15) which extends above the ski, in the runner area. One end of the plate (15) is connected to the ski by a linkage (17, 18, 19) which permits this end to slide freely in relation to the ski. A stop blocks this sliding motion beyond a determinate ski flexion. The other end of the plate is connected to the ski by a linkage (30, 33, 31) which can become deformed longitudinally by elastic stretching. This linkage is constituted by a glue layer (33) which exhibits both adhesive and stretching properties.

Abstract: Ski, especially an alpine ski, having the shape of an elongated beam including a core, a lower reinforcement and an upper reinforcement and including, in the assembly zone of the bindings, at least one shock absorption element, wherein the shock absorption element is arranged on the first upper reinforcement and beneath a second upper central reinforcement.
