Every day, the organ shortage crisis takes away lives of 17 patients (Health Resources & Services Administration, 2022). The number who require transplants significantly exceeds possible donors, and consequently, most pass while waiting for a matching donor organ. To address this issue, 3D bioprinting was suggested as method by which could receive functioning replica their own biocompatible...

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.                                                  material & methods: first, gelatin...

in the past decade, electrospinning as a facile and effective means in producing nanofibers with diameters ranging from microns down to a few nanometers has been developed and considered important. in this work, electrospinning of an interesting natural biopolymer, sodium alginate, has been investigated. the results showed that water solution of sodium alginate cannot be electrospun into nanofi...

background and objectives: edible films and coatings are effective method for decreasing oxidation and increasing the shelf life of pistachios. the present study investigated the effect of an edible gelatin coating containing ascorbic acid (aa: 1% w/v) and propyl gallate (pg: 100 ppm) on the oxidative stability and sensory properties of roasted pistachio nuts. materials and methods: pistachios ...

Nature builds biological materials from limited ingredients, however, with unparalleled mechanical performances compared to artificial materials, by harnessing inherent structures across multi-length-scales. In contrast, synthetic material design overwhelmingly focuses on developing new compounds, and fails reproduce the properties of natural counterparts, such as fatigue resistance. Here, a si...

microencapsulation has become a common technique in the production of controlled release dosage forms. many results have been reported, concerning the use of alginate beads as controlled release drug formulations. alginate has a unique gel-forming property in the presence of multivalent cations, in an aqueous medium. ibuprofen is an excellent analgesic and antipyretic, non-steroidal anti-inflam...

In recent years, encapsulation of drugs and antigens in hydrogels, specifically in calcium alginate particles, is an interesting and practical technique that was developed widespread. It is well known that alginate solution, under proper conditions, can form suitable nanoparticles as a promising carrier system, for vaccine delivery. The aim of this study was to synthesis alginate nanoparticles ...

alginate hydrogel and honey have a notably effect on wound healing process, therefore assessment of combined impact of those are essential. in this study, the effect of homey-based alginate hydrogel, alginate hydrogel and commercial alginate dressings in recovery of wound in a mouse model was studied. in this study, 20 wistar rats were divided into four groups of five. one wound with dimension ...
