Disclosed are Somatostatin receptor ligands comprising a peptide moiety, pharmaceutical compositions and uses thereof. Disclosed are also synthetic Somatostatin receptor ligands comprising a cyclic peptide moiety and an active agent moiety covalently bonded to the cyclic peptide moiety through a nitrogen atom of a side chain functional group of an internal residue of the cyclic peptide moiety, pharmaceutical compositions and uses thereof. Disclosed are also synthetic Somatostatin receptor ligands comprising a cyclic peptide moiety and a nanoparticle active agent moiety covalently bonded to the cyclic peptide moiety, pharmaceutical compositions and uses thereof.

The field of the disclosure relates generally to cancer cell destruction and, more specifically, to cancer cell destruction by photo-magnetic irradiation mediated multimodal therapy using smart nanostructures.

The present invention relates to the field of medicine, particularly to functionalised nanoparticles (NP) for use in cancer therapy (treatment or diagnosis), to pharmaceutical compositions or nano devices comprising same, and also to a method for obtaining said functionalised nanoparticles. The nanoparticles described in the present invention can be used specifically to treat cancer efficiently, as same can selectively detect tumour cells.

Disclosed herein are antimicrobial materials comprising a carbohydrate-templated microgel and a plurality of metal ions complexed thereto. The carbohydrate-templated microgel comprises a network copolymer molecule comprising a monoacrylate monomer, a crosslinking monomer, and a ligand monomer and wherein the microgel is prepared by the copolymerization of the monoacrylate monomer, the crosslinking monomer, and the ligand monomer in the presence of a carbohydrate or a carbohydrate derivative. The microgels have antimicrobial activity and allow for implementation of multiple, simultaneous mechanisms of antimicrobial action.

Embodiments of the present disclosure provide for magnetic particle conjugates, methods of making the magnetic particle conjugates, methods of using magnetic particle conjugates, micelles (also referred to as a “magnetic composite nanocarrier” (MCNC)), methods of making micelles, methods of using micelles, and the like.

Disclosed are a double stranded oligonucleotide construct, configured such that a hydrophilic material and a hydrophobic material are conjugated through a simple covalent bond or a linker-mediated covalent bond to both ends of a double stranded oligonucleotide in order to efficiently deliver an androgen-receptor-specific oligonucleotide into a cell, a nanoparticle capable of being produced by self-assembling double stranded oligonucleotide constructs in an aqueous solution through hydrophobic interactions, and a composition for preventing hair loss or promoting hair growth containing the double stranded oligonucleotide construct. The double stranded oligonucleotide construct including the androgen-receptor-specific oligonucleotide and the composition for preventing hair loss or promoting hair growth containing the same as an active ingredient can suppress the expression of an androgen receptor with high efficiency without side effects, and can thus exhibit excellent effects on preventing hair loss, particularly androgenetic alopecia, alopecia areata, and telogen effluvium, and promoting hair growth.

The present disclosure relates to therapeutic compositions, and more particularly to redox-responsive nanoparticles that allow controlled release of therapeutics, such as vascular endothelial growth factor inhibitors, in body tissues such as in the eye.

Compositions and methods for inducing a protective mucosal immunity against an antigen in a subject include the step of administering to a mucosal tissue an effective amount of a vaccine composition including the antigen or polynucleotide encoding an antigen associated or encapsulated within carriers such as poly(amine-co-ester) polymers in the form of particles (e.g., solid nanoparticles formed of PACE) or PACE copolymers and/or blends. Typically, the subject has previously been exposed to the antigen, for example, by administering to the same subject via a systemic or mucosal route of administration a priming antigen. In some embodiments, the polynucleotides-based vaccines are messenger RNAs encoding a viral antigen such as a coronavirus spike protein sequence, or a portion thereof. In preferred embodiments, the vaccine composition is administered intranasally.

Surface-modified cell containing a cell and a conformal coating on the extracellular surface of the cell are described. The conformal coating contains two or more layers containing particles (e.g. nanoparticles) or macromolecules. The cell is an islet cell, a B cell, or a T cell. The macromolecules or particles are formed from zwitterionic polymers. Covalent linkages are employed to link the particles or macromolecules to a cell surface molecule containing an abiotic functional group, or between macromolecules and/or particles in adjacent layers. Also described are methods of making and using a surface-modified cell.

Described herein are antimicrobial (e.g., antibacterial, antiviral) compositions and methods of using such compositions.
