Abstract: The present disclosure relates to nanoparticles and the uses thereof in medicine, in particular for the treatment of tumours.

Abstract: The invention relates to a statistical polysaccharide with a weight-average molecular weight of between 100 kDa and 1000 kDa of the following formula (I): in which: each Rc independently represents a group containing a chelating agent, each Z independently represents a binder which may be a single bond or a hydrocarbon chain containing between 1 and 12 carbon atoms, said chain able to be either linear or branched and being able to contain one or more unsaturations and being able to contain one or more heteroatoms, preferably chosen from nitrogen, oxygen, sulfur and atoms of the halogen family, x is between 0.005 and 0.7, preferably between 0.05 and 0.7, and preferentially between 0.2 and 0.6, y is between 0.01 and 0.7, preferably between 0.05 and 0.2, the ratio of y/x being greater than or equal to 0.05, preferably greater than or equal to 0.15, and the sum of x+y being greater than or equal to 0.30, preferably greater than or equal to 0.35.

Abstract: The present invention relates to the field of medical devices, more particularly the field of devices for extracting circulating molecules from the blood of a mammal, and their therapeutic uses, in particular in treating sepsis, cytokine release syndrome and/or any other form of systemic inflammatory response or cytokine shock, caused by bacterial, parasitic, fungal or viral infections, in particular caused by a viral infection, for example coronaviruses with human respiratory tract tropism.

Abstract: The invention concerns the field of medical devices, more particularly devices for joint extraction, within an organism, of at least one metal cation and at least one target molecule. In order to do this, the device comprises: a) at least one ligand exhibiting specific affinity for the target molecule; b) at least one means for extraction of the metal cation, said means being a perfusion fluid comprising at least one chelating agent, the perfusion fluid being contained in a dialysis or microdialysis system. The use of these devices makes it possible, for example, to prevent and/or treat pathologies linked to dysregulation of the homeostasis of metals and/or target molecules in the organism, for example neurological diseases and/or proteinopathies.
