Antioxidant and Protective Effects of the Polyphenolic Glycoconjugate from L. Herb in the Prevention of Inflammation in Human Cells.

Herein, structural and biological studies of a complex biopolymer (polyphenolic glycoconjugate) isolated from the flowering parts of L. () are presented. Spectroscopic analyses (UV-Vis and H NMR) of the aglycone component of confirmed that it consists mainly of aromatic and aliphatic structures characteristic of polyphenols.

Biological Properties of Low-Toxicity PLGA and PLGA/PHB Fibrous Nanocomposite Implants for Osseous Tissue Regeneration. Part I: Evaluation of Potential Biotoxicity.

In response to the demand for new implant materials characterized by high biocompatibility and bioresorption, two prototypes of fibrous nanocomposite implants for osseous tissue regeneration made of a newly developed blend of poly(l-lactide--glycolide) (PLGA) and syntheticpoly([]-3-hydroxybutyrate), PLGA/PHB, have been developed and fabricated. Afibre-forming copolymer of glycolide and l-lactide (PLGA) was obtained by a unique method of synthesis carried out in blocksusing Zr(AcAc)₄ as an initiator. The prototypes of the implants are composed of three layers of PLGA or PLGA/PHB, nonwoven fabrics with a pore structure designed to provide the best conditions for the cell proliferation.
