Therapeutic protein depots have limited clinical success because of the presence of critical preparation barriers such as low encapsulation, uncontrolled release, and activity loss during processing and storage. In the present study, we used our novel protein-nanoencapsulation (into sugar-glass nanoparticle; SGnP) platform to prepare a protein depot to overcome the abovementioned formidable challenges. The SGnP-mediated microparticle protein depot has been validated using four model proteins (bovine serum albumin, horseradish peroxidase, fibroblastic growth factor, and epidermal growth factor) and model biodegradable poly(lactic--glycolic acid) polymer system. The results show that our protein-nanoencapsulation-mediated platform provides a new generic platform to prepare a protein depot through the conventional emulsion method of any polymer and single/multiple protein systems. This protein depot has the required pharmaceutical properties such as high encapsulation efficiency, burst-free sustained release, and protein preservation during processing and storage, making it suitable for off-the-shelf use in therapeutic protein delivery and tissue engineering applications.

Severe distortions in the development of many basic psychological functions that are not normal for any stage in development. These distortions are manifested in sustained social impairment, speech abnormalities, and peculiar motor movements.
A nervous tissue specific protein which is highly expressed in NEURONS during development and NERVE REGENERATION. It has been implicated in neurite outgrowth, long-term potentiation, SIGNAL TRANSDUCTION, and NEUROTRANSMITTER release. (From Neurotoxicology 1994;15(1):41-7) It is also a substrate of PROTEIN KINASE C.
Composite materials composed of an ion-leachable glass embedded in a polymeric matrix. They differ from GLASS IONOMER CEMENTS in that partially silanized glass particles are used to provide a direct bond to the resin matrix and the matrix is primarily formed by a light-activated, radical polymerization reaction.
A framework for development and promotion of common data formats and exchange protocols linked in a way that can be read directly by computers. Semantic Web is a platform for sharing and reusing data across application, enterprise, and community boundaries, by linking concepts rather than just documents.

Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
Gene therapy is the use of DNA as a pharmaceutical agent to treat disease. It derives its name from the idea that DNA can be used to supplement or alter genes within an individual's cells as a therapy to treat disease. The most common form of gene th...
