The invention relates to a new form of a drug in the form of anthracycline encapsulated with a polysaccharide selected from epirubicin, daunorubicin, doxorubicin, idarubicin, especially encapsulated with dextran, for use in the treatment of specific tumours.

Provided herein is chitosan dually derivatized with arginine and gluconic acid; and methods of making and using the same, e.g., for gene delivery in vivo.

The present invention relates to the field of medical devices, more particularly to devices for extracting metals from an organism. The use of these devices makes it possible, for example, to prevent and/or treat pathologies linked to dysregulation of metal homeostasis in the organism, for example neurological diseases.

The present disclosure provides bioorthogonal compositions for delivering agents in a subject. The disclosure also provides methods of producing the compositions, as well as methods of using the same.

Blood-brain barrier permeable peptide compositions that contain variable antigen binding domains from camelid and/or shark heavy-chain only single-domain antibodies are described. The variable antigen binding domains of the peptide compositions bind to therapeutic and diagnostic biomarkers in the central nervous system, such as the amyloid-beta peptide biomarker for Alzheimer's disease. The peptide compositions contain constant domains from human IgG, camelid IgG, and/or shark IgNAR. The peptide compositions include heavy-chain only single-domain antibodies and compositions with one or more variable antigen binding domain bound to one or more constant domains.

Provided herein are particles comprising a polymer substrate comprising one or more hyaluronic acid chains; and two or more peptide moieties bound directly to each hyaluronic acid chain. In some embodiments, the two or more peptide moieties comprising collagen-binding peptide (CBP) and von Willebrand binding peptide (VBP). The particles can be utilized in, e.g., methods of hemostatic treatment.

A phosphorous compound such as STMP is used as a cross-linking agent while making a starch nanoparticle in an emulsion process. Negative charge of the nanoparticle is reduced or reversed by adding cations and/or cationizing the starch optionally while forming the nanoparticles. Anionic active agents, such as fluoride or fluorescein, are optionally incorporated into the nanoparticle during the formation process. For example, a fluoride salt can also be used, which promotes the crosslinking reaction while also providing fluoride in the nanoparticle. The retention of both calcium and fluoride in the nanoparticle is improved when both salts are used. Alternatively, the nanoparticle may be used without added calcium and/or fluoride. The nanoparticles may be useful for tooth remineralization, the treatment of dentinal hypersensitivity, to treat caries, or as a diagnostic agent to locate carious lesions.

In certain embodiments, this disclosure provides methods to generate DNA. RNA and/or DNA-peptide nanostructures based chimeric antigen receptor (CAR) T cell (engineered T cell) for cancer immunotherapy, and compositions made by these methods.

The invention provides a new method for preparing ultra-small polymeric-lipidic delivery nanoparticles (USDNs) that were synthesized by a nanoprecipitation method followed by a layer-by-layer nanodeposition. The USDNs particle size can be controlled between 5-25 nm and provides loading capacities of 22.12% to 72.08%. Moreover, the USDNs platform provides pH controlled drug release, within a terminal release ratio of 68% at pH 5.0 and almost no release to pH of 7.5. Furthermore, based on their small sizes (5-25 nm) and unique composition, the USDNs penetrates the skin strata efficiently, release the payload at the target site as topical or transdermal treatment of a variety of skin disorders. Additionally the USDNs system can be used to treat and diagnoses other crucial diseases (Cancer, Alzheimer, etc) can be combined with various micro-needles or needles free array technologies for special application.
