Carbonate apatite (CO₃Ap) foam has gained much attention in recent years because of its ability to rapidly replace bone. However, its mechanical strength is extremely low for clinical use. In this study, to understand the potential of gelatin-reinforced CO₃Ap foam for bone replacement, CO₃Ap foam was reinforced with gelatin and the resulting physical characteristics were evaluated. The mechanic...

1. The findings of Robertson, Sia, and Woo with regard to the preservative action of 0.1 per cent gelatin in suspending fluids for the pneumococcus have been confirmed for the streptococcus. 2. In gelatin-citrate, gelatin-Locke's, and gelatin-"20:1" solutions, the streptococcus will live for 3 days or longer at room temperature and for 12 hours or longer at incubator temperature in dilutions as...

This study focused on the degradation properties of gelatin microparticles incorporated in calcium phosphate (CaP) cement and the subsequent effect of these composites on bone formation. Positively charged alkaline gelatin (type A) microparticles or negatively charged acidic gelatin (type B) microparticles were incorporated in CaP cement, which was implanted in critical-sized cranial defect in ...

23 The rheological and functional properties of gelatin from the skin of bigeye 24 snapper (Priacanthus hamrur) fish were assessed. The protein content of dried gelatin 25 was 94.6% and moisture content was 4.2 %. The amino acid profile of gelatin revealed 26 high proportion of glycine and imino acids. The bloom strength of solidified gelatin was 27 108 g. The average molecular weight of fish s...

This study investigates the effects of the gelatin concentration (10-40%, w/v), freezing temperatures (from -20℃ to -50℃) and freezing methods on the structural and physical properties of gelatin matrices. To freeze gelatin, the pressure-shift freezing (PSF) is being applied at 0.1 (under atmospheric control), 50 and 100 MPa, respectively. The freezing point of gelatin solutions decrease with i...

Fish gelatin and chitosan were used to develop composite biodegradable films using two strategies: (i) the mixture of both polymers to obtain homogeneous polymer matrixes and (ii) the formation of two layers. The films produced were characterized in terms of water absorption, solubility, water vapour permeability and mechanical properties. Both strategies revealed to produce films with a high s...

Blastocyst implantation trophoblast attachment proteases rabbit Two hypotheses have been proposed for the origin of the gelatin dissolving enzyme involved in the dissolution of blastocyst coverings in the rabbit: trophoblastic vs. matern al origin. In aseries of experiments described in the present communication, egg coverings without living blastocyst tissue (mucoprotein-covered Sephadex beads...

Controlled release of a chemokine, stromal-cell-derived factor-1 (SDF-1), could be achieved with gelatin hydrogels of release carrier. Gelatin was chemically derivatized to give it different electric charge and hydrophobicity. Among the derivatives, succinylated gelatin (Succ) of an anionic charge was the most suitable for preparation of the hydrogel in terms of SDF-1 release. The time profile ...
