Abstract: Device for inspecting the stability of a dental implant (1) in a bone (2), the implant having a free end (1a) and an end (1b) buried in the bone (2). The device comprises an ultrasonic transducer (12) for emitting and collecting an ultrasonic wave reflected from a contact interface (4) between the implant (1) and the bone (2), and providing a measurement signal representing the reflected ultrasonic wave. The device also comprises a processing unit for computing, based on the measurement signal, an indicator (IN) whose value makes it possible to evaluate the integration of the implant (1) into the bone (2). The indicator (IN) corresponds to the average energy of the measurement signal over a time interval (t1-t2) starting at a first time (t1) and ending at a second time (t2). The first time (t1) is between 20 and 80 ?s after the start of the emission of the ultrasonic wave.

Abstract: The invention relates to the use of gingival fibroblasts for obtaining a cellular composition for treating arterial-remodelling pathology, for example an aneurysm, post-cryoplasty stenosis and restenosis, an aortic dissection or atherosclerosis.

Abstract: A charged biomaterial including at least one first hydrophilic polymer, and superparamagnetic iron oxide particles complexed with a second hydrophilic polymer substantially identical to or different from the first hydrophilic polymer, wherein the superparamagnetic iron oxide particles complexed with the second hydrophilic polymer are distributed substantially homogeneously and substantially without aggregates in the first hydrophilic polymer. A process for preparing a charged biomaterial including forming an aqueous solution of hydrophilic monomers and superparamagnetic iron oxide particles complexed with a hydrophilic polymer including monomers substantially identical to or different from the hydrophilic monomers, polymerizing the solution and forming a polymer hydrogel in which are distributed substantially homogeneously and substantially without aggregates the superparamagnetic iron oxide particles complexed with the hydrophilic polymer.

Abstract: A cell separation process for the isolation of pathogenic cells in a small concentration in a biological fluid specimen, including treating the biological specimen to modify in a differential manner selected rare cells and other cells and causing differential migration of cells that reacted during treatment versus cells that did not react during treatment.
