BACKGROUND In an attempt to prepare scaffolds with porosity and compressive strength as high as possible, we prepared porous β-tricalcium phosphate (TCP) scaffolds and coated them with regenerative medicine-grade gelatin. The effects of the gelatin coating on the compressive strength and in vivo osteoblast compatibility were investigated. METHODS Porous β-TCP scaffolds were prepared and coate...

Characteristics and properties of gelatin from goat skin pretreated with NaOH solutions (0.50 and 0.75 M) for various times (1 to 4 days) were investigated. All gelatins contained α-chains as the predominant component, followed by β-chain. Gelling and melting temperatures of those gelatins were 23.02°C to 24.16°C and 33.07°C to 34.51°C, respectively. Gel strength of gelatins increased as NaOH c...

The swelling of isoelectric gelatin added to various volumes of acid of different concentration at 5 degrees C. has been determined. The swelling is determined only by the concentration of the supernatant solution at equilibrium and is independent of the volume of acid. Similar experiments with unpurified gelatin show that in this case, owing to the presence of neutral salts the swelling is a f...

background :gelatin and chitosan are known as biodegradable and biocompatible biopolymers.these biopolymers have recently receivedincreasingly more attention for tissueengineering.the aim of this study was to evaluate the toxicity effects of gelatin-chitosan film on bone marrow stromal cell(bmscs) culture in rat.                                                  materials & methods: first, gelat...

This study deals with the effect of gelatin on physical and mechanical properties of  calcium phosphate bone cements. The mixture of tetracalcium phosphate (TTCP) and dicalcium phosphate (DCPA) as the cement powder was mixed with 6 wt% Na2HPO4 solution containing different amount (0, 2, 5 and 8% in w/w) of foamed gelatin as liquid phase. The physical properties were determined in the terms of s...

milk-based dairy desserts have important role in human diet because of their nutritional values. the aims of this study were to investigate the effect of hull-less barley malt flour and gelatin adding on different aspects of dairy dessert with the goal of increasing nutritional value and quality parameters. desserts were prepared by different gelatin concentration (0, 0.5, 1.0, 1.5 and 2%) and ...

results gelatin films exhibited good tensile strength and elongation at break, water solubility, swelling, and water vapor permeability. incorporation of tam into the gelatin films caused a significant decrease in tensile strength and swelling, and a significant increase in elongation at break, water solubility, water vapor permeability and whiteness of the films. gelatin films exhibited low an...

Fabricating ideal scaffolds for bone tissue engineering is a great challenge to researchers. To better mimic the mineral component and the microstructure of natural bone, several kinds of materials were adopted in our study, namely gelatin, polycaprolactone (PCL), nanohydroxyapatite (nHA), and bone powder. Three types of scaffolds were fabricated using electrospinning; gelatin/PCL, gelatin/PCL/...
