Abstract: The present invention concerns a method for detecting aggregate-forming circulating protein forms in a biological sample of human origin that may contain said aggregate-forming circulating protein forms, characterized in that it uses a non-protein agent I producing aggregation of the circulating forms of the noninfectious proteins involved in pathological aggregation processes of the central nervous system and/or a non-protein agent II for capturing the natural aggregrates of aggregate-forming circulating protein forms or the aggregates induced by said agents I.

Abstract: The present invention relates to a method for selectively extracting membrane proteins using at least one calixarene of formula (I). The use of calixarenes in the method according to the invention enables the selective solubilization of the membrane proteins while preserving the three-dimensional structure that is essential to the enzymatic activity thereof.

Abstract: The present invention relates to a method preparing co-colloidal dispersions of active hydrophobic substances, such as pharmaceutical products, products having cosmetic properties or any other chemical product. The co-colloidal dispersions thus obtained are characterized in that they are formed by amphiphilic complexes resulting from combinations by non-covalent bonds between a hydrophobic active substance and a suitable hydrophilic molecule.

Abstract: A process of concentration by precipitation of PrPsc for detecting or diagnosing PrPsc, wherein a tissue or biological fluid stemming from or obtained from an animal or human organism is brought together with an antibiotic from the family of aminoglycosides, preferably streptomycin or one of its derivatives. The use of such an antibiotic for eliminating PrPsc from a tissue or biological fluid and a kit for diagnosing pathologies associated with the presence of PrPsc is also disclosed.

Abstract: A method for detecting PrP in a biological human or animal sample that may contain said PrP. The method is characterized in that it uses a molecule containing at least one positive charge and/or at least one glycosidic bond and a ligand other than a protein ligand selected from macrocyclic ligands and glycosaminoglycans.

Abstract: This invention relates to co-crystals of at least one molecule of calyx[n]arene or at least one of its derivatives, and at least one biologically active molecule, compositions and medicines including them, and the use of these co-crystals and methods used to obtain them.

Abstract: The invention relates to a method for detecting PrP in a biological human or animal sample that may contain PrP. The inventive method is characterised in that it uses a molecule containing at least one positive charge and/or at least one osidic bond and a ligand other than a proteinic ligand selected from macrocyclic ligands and glycosaminoglycanes.

Abstract: A process for detecting the forms of the prion pathogens responsible for subacute, transmissible, spongiform encephalopathies, including a macrocyclic adjuvant ligand (AML), free or bound to a support, that is added to a biological sample capable of containing PrPsc, the resulting suspension then being reacted with an anti-PrPsc antibody, and the presence of PrP is then detected.

Abstract: Non-hydroxyalkylated cyclodextrins are disclosed wherein at least one primary alcohol function (CH2OH) is substituted, the —OH portion being replaced by a substituent with formula —O—CO—R or —NR1R2, where: R, R1 and R2 independently represent a linear or cyclic, saturated or unsaturated, hydroxylated or non-hydroxylated alkyl group containing 1 to 30 carbon atoms, preferably 1 to 22 carbon atoms, more preferably a fatty chain containing 2 to 22 carbon atoms. These cyclodextrins are used as vectors for at least one active ingredient, in particular to encourage tissue penetration, in a cosmetic application, or for the production of pharmaceutical compositions, in particular dermopharmaceuticals.
