Abstract: Aim: To develop hydrogel films for hydrophilic drug delivery with citric acid-cross-linked Hydroxypropyl Methylcellulose (HPMC) and (MC). Materials Methods: The existing study is concerned the development of HPMC/MC employing acid as a cross-linking agent in order to accomplish loading while simultaneously releasing drugs (ciprofloxacin hydrochloride). Thermal analysis ATR-FTIR spectr...

Noncovalent attachment of avidin to the membrane of prebiotinylated red blood cells (RBCs) induces lysis via the alternative pathway of complement (APC). Lysis is not species-dependent; RBCs from humans, rabbits, rats, and sheep were lysed with both autologous and all heterologous sera. Both biotinylated and native cells were not lysed. Lysis was observed at an avidin surface density of about 1...

This paper reports a method for preparing artificial leather with high comfort and useful mechanical property. Blending thermoplastic polyurethane elastomer (TPU), Toluene diisocyanate (TDI) prepolymer 4,4-Methylene bis(2-chloroaniline) (MOCA), nanofiber was obtained by using online reactive electrospinning technology heat cross-linking. Compared the commercial PU leather, tensile strength of f...

The aim of present study involves preparation and characterization of floating microspheres using trimetazidin dihydrochloride as a model drug to increase the residence time in the stomach without contact with the mucosa, Floating microspheres were prepared by the capillary extrusion technique using chitosan as polymer and sodium lauryl sulphate as cross linking agent. The surface morphology of...

In dentistry, pure gutta-percha (trans-1,4-polyisoprene (TPI)) is widely used as a main component of root canal filling materials. TPI has an interesting shape memory formed through cross-linking, and this characteristic is expected to be very effective for development of novel dental treatments; in particular, modification of the shape recovery temperature to the intraoral temperature (37 ̋C) ...

In this study, the development of a model tracheal mucus with chemical composition and physical properties (bulk viscoelasticity and surface tension) matched to that of native tracheal mucus is described. The mucus mimetics (MMs) were formulated using components that are abundant in tracheal mucus (glycoproteins, proteins, lipids, ions, and water) at concentrations similar to those found native...

PURPOSE GS-E3D is a newly developed pectin lyase-modified red ginseng extract. The purpose of this study was to evaluate the inhibitory effects of GS-E3D against advanced glycation end products. METHODS In this study, we evaluated the inhibitory effects of GS-E3D on the formation of advanced glycation end products (AGEs) and their cross-linking with collagen in vitro and in streptozotocin-ind...

We investigated the feasibility of oleuropein as a cross-linking agent for fabricating three-dimensional (3D) porous composite scaffolds for bone tissue engineering. Human-like collagen (HLC) and nanohydroxyapatite (n-HAp) were used to fabricate the composite scaffold by way of cross-linking. The mechanical tests revealed superior properties for the cross-linked scaffolds compared to the uncros...
