Recovery and Purification of Cutin from Tomato By-Products for Application in Hydrophobic Films.

Tomato pomace is a low-cost, renewable resource that has been studied for the extraction of the biopolyester cutin, which is mainly composed of long-chain hydroxy fatty acids. These are excellent building blocks to produce new hydrophobic biopolymers. In this work, the monomers of cutin were extracted and isolated from tomato pomace and utilized to produce cutin-based films.

Blood absorption capacity of different xenograft bone substitutes. An in-vitro study.

Background: Commercially available xenograft blocks, claim to have adequate characteristics to interact with biological media and thus permitting biological fluid absorption. The objective of this in vitro study was to compare the blood absorption capacity of four different xenograft block materials of different composition of collagen and porosity.

Material And Methods: Four brands of xenograft block materials were used (NuOss®, Bio-Oss®, Osteobiol® and Smartbone®).
