Gelatin composite films were prepared from gelatin solutions (10% w/v) containing multi-walled carbon nanotubes (MWCNT, 0.5, 1, 1.5, and 2% w/w gelatin) as nanofiller. The water solubility, water swelling, water uptake, water vapor permeability (WVP), mechanical, and antibacterial properties of the films were examined. Water solubility, water swelling, water uptake, and WVP for gelatin films we...

The human 72-kDa (CLG4A) and 92-kDa (CLG4B) type IV collagenases contain a domain consisting of three contiguous copies of the fibronectin (FN)-derived type II homology unit (T2HU), T2HU-1, T2HU-2, and T2HU-3. To investigate the functional role of this domain, we have constructed plasmids expressing beta-galactosidase fusion proteins with one or more of the CLG4B-derived T2HU. The gelatin bindi...

Background This study examines the effects of adding gelatin to a starch-chitosan composite foam, focusing on the altered structural and biological properties. The compressive modulus of foams containing different gelatin concentrations was tested in dry, wet, and lyophilized states. MC3T3 mouse osteoblast cells were used to test the composite's ability to support cell growth. The stability of ...

The objective of this study was to evaluate the proliferation and chondrogenic differentiation of rat bone marrow-derived mesenchymal stem cells (MSCs) cultured with gelatin hydrogel microspheres of cell scaffold which can release transforming growth factor-beta1 (TGF-beta1). Gelatin was dehydrothermally cross-linked in different conditions in a water-in-oil emulsion state to obtain gelatin hyd...

INTRODUCTION Carriers for controlled drug release offer many advantages compared with conventional dosage forms. Gelatin has been investigated extensively as a drug delivery carrier, due to its properties and history of safe use in a wide range of medical applications. AREAS COVERED Gelatin was shown to be versatile due to its intrinsic features that enable the design of different carrier sys...

For tissue engineered bone constructs, calcium phosphate cement (CPC) has a high potential as scaffold material because of its biocompatibility and osteoconductivity. However, in vivo resorption and tissue ingrowth is slow. To address these issues, microspheres can be incorporated into the cement, which will create macroporosity after in situ degradation. The goal of this study was to investiga...

Polymer blends of cold water soluble starches (amylose or amylopectin soluble starch) with gelatin were prepared using solvent casting method. The solid state miscibility and polymer-polymer interactions between the constituent polymers were studied by fourier transforms infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential scanning calorirmetry (DSC), light optical microscopy (OP...

Many methods have been devised to detect the action of bacterial cultures in or on gelatin media. The traditional gelatin stab technique involves incubation of the culture below the thermal liquefaction point of the gelatin in order to inaintain the gel structure so that the shape and size of the liquefied portion can be observed. A long incubation time is usually required. Bertiau (1914) sugge...

In a general way the chemical nature and composition of gelatin have been established for many years, but the more thorough chemical study of various forms of connective tissue, which has been carried on so successfully during the last decade, has revealed the existence of at least three distinct varieties of collagen, characterized by marked differences in chemical composition. The collagen of...

~emistry of the crosslinking of gelatin is a complex phenomenon. the nature of which is dependent on several factors. The present manuscript represents an attempt to answer some specific basic science issues. Two "stress" conditions are commonly known in connection with gelatin capsules. The first condition is induced by exposure to formaldehyde. The second stress condition is created by exposi...
