There is a medical need for robust, biocompatible hydrogels that can be rapidly crosslinked in situ through the use of gentle and non-toxic triggers, which could be used as a surgical adhesive, a bone-inductive material, or for drug and gene delivery. The complete gelation system described here includes calcium-loaded liposomes, hrFactor XIII. thrombin, and an enzymatic substrate based on a fou...

The aim of this study was the formulation and examination of a novel thermoresponsive and bioadhesive, in situ gelling drug delivery system, which can be used in the treatment of oesophageal pain and inflammation. A bioadhesive cellulose derivative (Metolose) 60SH) was used as a thermoresponsive material, because Metolose has thermal gelation properties at certain temperature. The thermal gelat...

The main aim of the present investigation was to develop in situ gelling mucoadhesive liquid suppositories of ondansetron by using mucoadhesive polymers such as sodium alginate, methyl cellulose and polyvinylpyrrolidone. Polyethylene glycol was used to modify gelation temperature. Mucoadhesive liquid suppositories of ondansetron were prepared by adding mucoadhesive polymers (0.8% w/w) to the fo...

An in situ fast-forming BMSC-laden Col-PEG/SF hydrogel with short gelation time, great biocompatibility and good mechanical properties was fabricated for cartilage regeneration.

This paper reports the rheological behavior of chitosan solutions that have been cross-linked with different amounts of genipin, at body temperature and physiological pH. The effect of the cross-linker loading on the rheological properties of hydrogels has been evaluated. The oscillatory time sweep method was used to monitor the dynamic viscoelastic parameters during in situ (i.e., in the rheom...

Alginate is a commonly used biomedical hydrogel whose in vivo degradation behavior is only beginning to be understood. The use of alginate in the central nervous system is gaining popularity as an electrode coating, cell encapsulation matrix, and for duraplasty. However, it is necessary to understand how the hydrogel will behave in vivo to aid in the development of alginate for use as a neural ...

The present study was aimed at formulating thermoreversible in situ gel of local anesthetic by using xyloglucan based mucoadhesive tamarind seed polysaccharide (TSP) into periodontal pocket. Temperature-sensitive in situ gel of lidocaine hydrochloride (LH) (2% w/v) was formulated by cold method. A full 3(2) factorial design was employed to study the effect of independent variables concentration...
