摘要:
The invention relates to a cell culture device. This cell culture device (100), intended for receiving cells with their culture medium, is characterised in that it contains at least one cell-supporting layer of porous material, this layer being obtained by dehydration of an aqueous gel which is poured directly either into said well bottom (110-111), or into the bottom of a cradle or insert (150) of a size which is adapted for being insertable into the volume of the well. The invention enables a culture to be made which can be automated.
摘要:
The invention concerns a substance for restoring normal co-expression and interaction between LOX and NRAGE proteins. In particular, the invention concerns the use of an effective amount of at least one substance modulating the expression and/or the activity of LOX having the sequence ID N°1 and/or modulating the expression and/or the activity of NRAGE having the sequence ID N°2 for making a composition for modulating the interaction between the LOX and NRAGE proteins so as to regulate the balance between the phenomena of proliferating cells, of differentiation and apoptosis, in particular in cases where the interaction between LOX and NRAGE proteins is absent or altered. The invention enables in particular skin aging, lichen planus, a graft-versus-host reaction disease, an eczema, a psoriasis, and a cancer, in particular an epithelial cancer, particularly an epithelial skin cancer, of basocellular type, or of spinocellular type to prevented or treated.
摘要:
This invention relates to the use of a preparation comprising sulfated oligosaccharides which trap spermine and/or spermidine, as an active slimming ingredient in a cosmetic, pharmaceutical and/or nutraceutical composition. One aspect of the invention is to supply a cosmetic, pharmaceutical or nutriceutical composition with a slimming effect.
摘要:
The invention concerns active substances modulating the expression of the receptors of the products of the POMC gene (MC-IR, MC-2R, and the μ opioid receptor), and possibly modulating the expression of POMC in cutaneous cells, notably to modulate the proliferation and differentiation of epidermal cells in order to re-epithelial, maintain innervation, irrigate the skin, or restore normal pigmentation, or to fight against aging, or to modulate pigmentation independently or not of cutaneous aging. The invention also concerns a method of screening such active substances.
摘要:
The invention relates to the use, as active ingredient, of at least one substance that promotes AGE deglycation, for the preparation of a composition, especially for limiting the presence of AGEs in a tissue. The invention relates in particular to the use of such a substance for the preparation of a composition for use in preventing and/or combating the decrease in flexibility and/or plasticity and/or elasticity and/or functionality of a tissue, and/or in preventing and/or combating ageing of a tissue, by promoting AGE deglycation in the tissue, wherein said tissue is preferably the skin, or the tissue wall of a blood vessel or of an organ.
摘要:
The present invention relates to the use of an active substance that promotes the inhibition of AGE formation, for the preparation of a composition for preventing and/or combating the decrease in elastic and plastic properties of tissues, and in particular of the skin, for inhibiting AGE formation, or for preventing and/or combating protein glycation at the cutaneous level. The invention also relates to a method of screening for such active substances.
