The disclosure relates to synthetic oligonucleotides that are unique in that they are RNA molecules that have the capacity to form a hydrogel. Also disclosed are DNA oligonucleotides that encode the RNA oligos so that the oligos can be prepared using in vitro transcription. The disclosure further pertains to pharmaceutical compositions comprising these hydrogels.
摘要:
The technology described herein is directed to compositions comprising at least a first porous biomaterial layer and a second impermeable biomaterial layer and methods relating thereto. In some embodiments, the compositions and methods described herein relate to wound healing, e.g. repair of wounds and/or tissue defects.
摘要:
The invention relates to a method for sterilising functionalised coated surfaces containing nucleotides and/or nucleotide derivatives, according to which a) the surface is coated in a functionalising manner with nucleotides and/or nucleotide derivatives such that there is an surplus thereof, wherein the surplus nucleotides and/or nucleotide derivatives as sacrificial strands are not washed out of the coating, b) the atmosphere above the coated surface is enriched with ethanol, and c) the coated surface is irradiated with ionising radiation.
摘要:
Methods for treating or preventing neointima stenosis are disclosed. The methods generally involve the use of a TGFβ inhibitor, a SMAD2 inhibitor, an FGF Receptor agonist, a Let-7 agonist, or a combination thereof, to inhibit endothelial-to-mesenchymal transition (Endo-MT) of vascular endothelial cells into smooth muscle cells (SMC) at sites of endothelial damage. The disclosed methods can therefore be used to prevent or inhibit neointimal stenosis or restenosis, e.g., after angioplasty, vascular graft, or stent. Also disclosed are methods for increasing the patency of biodegradable, synthetic vascular grafts using a composition that inhibits Endo-MT. A cell-free tissue engineered vascular graft (TEVG) produced by this method is also disclosed.
摘要:
Electrospun scaffolds crosslinked with acrylates and methods of making the same are provided. Because the crosslinking is carried out under mild conditions, biologically active agents are incorporated into the scaffolds in a facile manner.
摘要:
The present invention relates to a temperature-sensitive bioactive material carrier and to a method for preparing same. More particularly, the present invention relates to a temperature-sensitive bioactive material carrier and to a method for preparing same, wherein the carrier comprises a biodegradable amphiphilic block copolymer, wherein said coplymer comprises polysaccharides or both polysaccharides and succinic anhydrides as a hydrophilic block, and polylactides as a nonionic block. The hydrophilic polymer/polylactide copolymer according to the present invention forms stable composites in in-vivo conditions through ionic bonding or temperature-sensitive hydrophobic bonding to bioactive materials such as proteins, polynucléotides, or the like, thus enabling the easy in vivo delivery of bioactive material, and therefore can be used as an in vivo drug delivery system.
摘要:
The present invention relates to hydrogels based on hyaluronic acid based derivatives, that are more resistant than hyaluronic acid alone towards chemical and enzymatic degradation and are endowed with a mix of chemical and mechanical properties such that they are of optimal use in several surgeries, for instance for injection in bone fractures or cavities and for the production of coatings of prostheses in orthopedic surgery, as fillers in cosmetic and maxillo-facial surgery, as anti- adhesion barrier in the prevention of postoperative adhesions in abdominal and abdomino/pelvic surgey, and in general surgery. These hydrogels can be loaded with several different kinds of compounds having pharmacological and biological activity, that are then released from the hydrogel in the site of intervention.
