Chitosan with a molecular weight (MW) of 10 Da and 13% degree of acetylation (DA) was extracted from the mycelia of the fungus Gongronella butleri USDB 0201 grown in solid substrate fermentation and used to prepare scaffolds by the freezedrying method. The mechanical and biological properties of the fungal chitosan scaffolds were evaluated and compared with those of scaffolds prepared using chi...

Every year, close to 8 million tons of waste crab, shrimp and lobster shells are produced globally, as well 10 oyster, clam, scallop mussel shells. The disposed frequently dumped at sea or sent landfill, where they modify soils, waters marine ecosystems. Waste a major by-product, which should become new raw material be used the best their potential. There number applications for in many fields,...

Animals with highly inducible traits may show no inducible response when exposed to a related but wholly novel cue. This appears to be true for the intertidal whelk Nucella lamellosa faced with a voracious introduced predator. In the laboratory, we exposed whelks to effluent from two species of predatory crab, the native red rock crab Cancer productus and the invasive European green crab Carcin...

Background: Bone resorption due to tooth extraction leads unpredictable bone volume for future prosthetics. Crab shells were promoted as a solution prevent resorption, along with an effort reduce biological waste. Purpose: This study aimed analyze the expression of sialoprotein (BSP) and dentine matrix protein-1 (DMP1) in wound healing process tooth-extraction sockets after applying crab shell-...
