AIM Utilize the dual composition strategy to increase the pore size and solve the low cell infiltration capacity on random nanofiber meshes, an intrinsic limitation of electrospun scaffolds for tissue engineering applications. MATERIALS & METHODS Polycaprolactone and poly(ethylene oxide) solutions were electrospun simultaneously to obtain a dual composition nanofiber mesh. Selective dissoluti...

This study was designed to investigate whether 5-fluorouracil (5-Fu)-polycaprolactone sustained-release film in Ahmed glaucoma valve implantation inhibits postoperative bleb scarring in rabbit eyes. Eighteen New Zealand white rabbits were randomly divided into three groups (A, B and C; n = 6 per group). Group A received combined 5-Fu-polycaprolactone sustained-release film application and Ahmed...

In this work we bring together replicating rapid prototyping technology with electrohydrodynamic phenomena to develop a device with the ability to build structures in three-dimensions while simultaneously affording the user a degree of designing versatility and ease that is not seen in conventional computer numerically controlled machines. An attempt at reproducing an actual human ear using pol...

Attempts to improve formulation of topical products are a continuing process and the development of microandnanovesicular systems as well as polymeric microparticles has led to marketing of topical drugs and cosmetics usingthese technologies. Encapsulation of some well-known contact allergens in ethanolic liposomes have been reportedto enhance allergenicity compared with the all...

State-of-the-art tissue engineered heart valves are not strong enough to withstand aortic blood pressure levels. When a strong and slowly degrading scaffold is used, the starting position of valvular tissue engineering is a stronger valve and seeded cells are allowed more time to create a strong extracellular matrix. A polycaprolactone knitted patch with leaflets was developed as a valvular sca...

A binary blend of polycaprolactone and starch in 70:30 weight ratio (known under the tradename “Envar”) was blended in various weight ratios with organosolv lignin (L) and organosolv lignin butyrate (LB) by solvent casting and melt blending. The thermal transitions observed by DSC revealed behavior resembling that of native polycaprolactone (PCL). Depression in melting temperatures obtained by ...

BACKGROUND The combination of polycaprolactone and hyaluronic acid creates an ideal environment for wound healing. Hyaluronic acid maintains a moist wound environment and accelerates the in-growth of granulation tissue. Polycaprolactone has excellent mechanical strength, limits inflammation and is biocompatible. This study evaluates the safety and efficacy of bio-conjugated polycaprolactone mem...
