The invention provides compositions featuring chitosan and methods for using such compositions for the local delivery of biologically active agents to an open fracture, complex wound or other site of infection. Advantageously, the degradation and drug elution profiles of the chitosan compositions can be tailored to the needs of particular patients at the point of care (e.g., in a surgical suite, clinic, physician's office, or other clinical setting).

Described herein are compounds of Formula (I), polymers and implantable elements comprising compounds of Formula (II), and compositions and methods of use thereof. In particular, the compounds, modified polymers, implantable elements and related compositions may be used in methods for the prevention and treatment of a disease, disorder or condition in a subject.

The disclosure describes nanocarried and/or microcarried jasmonate compounds and their pharmaceutical compositions, as well as use thereof for treating or preventing angiogenesis-related or NF-κB-related disorders. Also disclosed are methods of making the nanocarried and/or microcarried compounds and their compositions.

The invention relates to chitin, a hydrolysate and a method for the production of at least one desired product from insects. More specifically, the invention relates to a method for the production of chitin and/or chitosan from insect cuticles, comprising a step in which insect cuticles are treated with an oxidising agent, followed by a step involving the enzymatic hydrolysis of the insect cuticles using a proteolytic enzyme.

The present invention relates to a beetle powder containing at least 67% by weight protein and at least 5% by weight chitin, the weight percentages relating to the total weight of the beetle powder. The invention is also directed to a method for preparing the beetle powder and to the uses thereof, in particular in human or animal nutrition.

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 is a product and process to produce a new inclusion of a Chitosan-based compound and herbal extract, to provide consistent and long-lasting antimicrobial, antiviral, antibacterial, antifungal, anti-spore, and anti-odor characteristics.

A plant-based functional polyester filament and a preparation method of the plant-based functional polyester filament are provided. The plant-based functional polyester filament includes polyester, and plant extract in a weight percentage range of approximately 0.1%-1.5%. The plant extract includes one or more of a peppermint extract, a valerian extract, a lavender extract, a wormwood extract, a chitin extract and a seaweed extract. The method includes preparing a plant-based functional polyester masterbatch, including: heating polyethylene terephthalate (PET) chips to a molten state, adding an antioxidant and a dispersant to the molten PET, stirring the molten PET, adding a protective agent and a plant extract to the molten PET, stirring the molten PET at a high speed, adding a modifier to the molten PET, obtaining a mixture by uniformly mixing the molten PET, and performing an extrusion granulation process on the mixture.

A composition comprising a doubly conjugated chitosan polymer or oligomer, and a functionalized metal work piece including the doubly conjugated chitosan polymer or oligomer.

The invention provides compositions featuring chitosan and methods for using such compositions for the local delivery of biologically active agents to an open fracture, complex wound or other site of infection. Advantageously, the degradation and drug elution profiles of the chitosan compositions can be tailored to the needs of particular patients at the point of care (e.g., in a surgical suite, clinic, physician's office, or other clinical setting).
