Definitions
- the invention relates to the implementation of simultaneous and / or sequential steps aimed at separating, extracting and / or isolating all or part of the components contained in the internal aragonitic organo-mineral layer and in the calcitic organo-mineral layer outer shell of marine bivalve molluscs such as: Pinctada Maxima- Margaritifera- Martensi- Fucata, as well as Tridacnae Gigas- Maxima- Hippopus Hippopus- Derasa- Tevaroa- Crocea- Squamosa, Porcelanus.
- the external calcitic organo-mineral layer of the shell of these same mollusks also consists of a mineral fraction, composed of prisms of calcite, another polymorphic form of calcium carbonate, crystallizing in the rhombohedral system and of a fraction organic also consisting of soluble and insoluble protein and non-protein components, pigments and metals.
- the outer calcitic organo-mineral layer is richer than the inner aragonitic organo-mineral layer in melanin pigments and in metals associated with porphyrins and enzymes.
- the active molecules contained in the organic fractions of the internal organo-mineral aragonitic and external calcitic layers of the shells of the molluscs mentioned above are protein and non-protein components extracted by cold hydrolysis. These components are soluble and insoluble biopolymers which group together proteins, polypeptides and polysaccharides, as well as bio-monomers, amino acids and monosaccharides. All of them have many biological and pharmacological, osteo-inducing and healing properties among others. These properties are due to the presence of glycoproteins related to growth factors.
- the methods conventionally used to extract these molecules do not make it possible to extract all of the molecules, in particular those of low molecular weight having interesting properties, mainly antibiomimetics such as glycosamines, as well as lipids and polyunsaturated fatty acids, without forget about pigments, metalloenzymes and metalloporphyrins.

They are mostly polar and non-polar compounds represented by hydroxylated and non-hydroxylated ceramides, sulfate and / or acetate cholesterols, triglycerides and omega 3s.
- fatty acids have anti-inflammatory and immune properties, that they seem to play an inhibitory role in the development of certain tumor processes, in rheumatoid arthritis and in autoimmune diseases, and that these same lipids and fatty acids induce overexpression of filaggrin, a protein of the surface layer of the skin which has inhibitory properties of membrane transglutaminase (set of insoluble protein polymers involved in certain dermatoses), we can therefore understand their interest in the formulation of preparations for therapeutic purposes.

- Step (c) of separation In order to separate the liquid phase and the solid phase from the saturated solution resulting from the hot percolation step (b), a separation step (c) can be applied to the saturated solution to recover on the one hand the liquid phase and on the other hand the solid phase.
- this separation step (c) can be carried out by centrifugation and the liquid phase recovered is called the supernatant and the solid phase recovered is called the pellet. Only this example is described here, but those skilled in the art will know how to implement separation techniques other than centrifugation to carry out this step (c).

- Sonication is a process using mechanical and acoustic waves in a liquid medium, for example using a sonotrode, at a frequency between 20 kHz and 200 kHz depending on the initial viscosity of the concentrate.
- sonication makes it possible to trigger and accelerate the reactions and hence, to modify and potentiate the pharmacological and pharmacodynamic properties of the active soluble molecules.
- cavitation causes the formation of highly reactive hydroxyl radicals, which results in an improvement in the yield of the reactions, a reduction in the reaction time of the molecules of interest between them and an exponential potentiation of the anti-radical properties of some of them.

- the stem of the femoral prosthesis and the cup are usually either sealed with a surgical cement based on methyl methacrylate or impacted.
- the use of the spheronized aragonite powder, with a particle size between 50 nm and 10 ⁇ m, is justified for the following reasons: the spheronization is intended initially to ensure better injectability and flowability of the cement and to promote the creation of an interconnected porosity with pores of 10 to 100 ⁇ m essential for osteoconduction.
- Soluble and insoluble proteins which stimulate cell differentiation and proliferation as well as osteogenesis, play a capital role in building bone architecture.

It results in depigmentation of the skin, either by diffuse plaques, by zones or generalized. It is manifested by the appearance of white patches due to the disappearance of melanocytes, cells that make melanin, the main pigment in the skin.
- the therapeutic possibilities are limited. They range from UVB use, topical corticosteroids and biosimilars, to topical preparations, and as a last resort to surgical melanocyte grafts or thin skin grafts.
