Abstract: The present invention refers to a method for the synthesis of a biodegradable calcium release material that shows controlled ion release properties for tissue engineering, biomaterials containing the calcium particles as well as the calcium particles obtainable therefrom. By varying the treatment temperature of the described method, the calcium material shows different calcium release profiles. Contrary to a specific chemical composition such as CaCO3 which is associated to a specific calcium release profile, the present invention allows a manifold of compositions, with a manifold of calcium release profiles, all starting from a single specific chemical composition calcium precursor. Therefore, the invention also relates to the use of the controllable release, calcium material in tissue regeneration such as wound healing processes.

Abstract: A device for simulating an endoscopic operation via natural orifice, including a physical model of a biological organ including main and inlet modules detachable from each other. The main module may define a main body of the organ with a cavity and the inlet module may define an inlet opening to the cavity of the main module corresponding to the inlet of the biological organ. The cavity of the main module is accessible through the inlet module by an endoscopic tool to actuate in the cavity of the main module. The main module may be configured in such a way that, in use, one or more simulation modules are attachable with the main module to simulate one or more events representative of the actuation of the endoscopic tool in the cavity of the main module.

Abstract: A lamp having a first module for being attached to a ceiling or wall element, a second module connected to the first module and being rotatable with respect to the first module along a first axis, a third module having one or more light-emitting elements, the third module being connected to the second module and rotatable with respect to the second module along a second axis, the second axis being substantially perpendicular to the first axis.
