Following preincubation of aprotinin with gelatin, the inhibitory effect on the trypsin activity was enhanced under the same condition as in the case of enhanced antigen-antibody reaction of aprotinin in gel in the presence of gelatin. In the immunochemical titration of aprotinin, gelatin treatment decreased the value of the equivalence point of aprotinin. Immunoprecipitation of aprotinin prein...

The discipline of tissue engineering opens up the ways for repair and regenerate damaged organs and tissues. In the current work biomimetic nanofibrous scaffolds were fabricated by electrospinning. Poly-L-lactic acid (PLLA) was blended with collagen and gelatin to fabricate PLLLA-collagen and PLLA-gelatin fibrous scaffolds respectively. Pure PLLA and gelatin scaffolds served as controls. All th...

Coating of gelatin and chitosan can improve fish fillet's quality, but the mechanism is not clear. Chitosan/gelatin coatings significantly prevented deterioration of golden pomfret fillet at 4 °C. Chitosan with 7.2% gelatin group showed the best effect on preserving the length of myofibril, which remained greater than 15 μm at day 17 of storage, while for control, chitosan and chitosan combined...

In recent years, there has been a great interest in using natural polymers in the composition of calcium phosphate bone cements to enhance their physical, mechanical, and biological performance. Gelatin is a partially hydrolyzed form of collagen, a natural component of bone matrix. In this study, the effect of blooming gelatin on the nanohydroxyapatite precipitation, physical and mechanical pro...

ease progressing to end-stage renal failure. Renal fibrosis is characterized by qualitative and quantitative changes in the composition of tubular basement membranes or interstitial matrices, tubular atrophy, and the accumulation of myofibroblasts. For chronic renal disease, persistent accumulation and deposition of extracelluar matrix (ECM) which lead to widespread tissue fibrosis, are observe...

Usually gelatin manufacturer utilises mammalian sources as principle sources to produce collagen. The collagen is partially hydrolysed to generate gelatin. However, Muslims and Jews can’t consume gelatin from pork products because of their religion and culture reasons. On the other hand, potential safety issue for gelatin made from slaughtered beef processing byproducts will pose problems such ...

Microencapsulation of liquid orange oil as a common flavoring agent in food industries by complex coacervation in a gelatin – gum arabic polymeric wall system was studied. At a fixed ratio of 10% w/v as concentration of the materials used in this study, trend of changes of microencapsulation process variables using different wall polymeric contents along with varying levels of the core to wall ...

Abstract Nowadays, continuous development of soft-electronics and wearable devices opens to the needs stretchable flexible materials able interface with human body. In this scenario, biopolymers are particularly intriguing given their biocompatibility biodegradability. For application in specific field material requires several properties such as biological mechanical performance thermal stabil...
