Amniotic Stem Cells Cultured on Thermoresponsive Polymers Allow Obtaining a Full Cell Sheet.

Amniotic stem cells promote adhesion and migration of epithelial cells. Obtaining a full sheet containing amniotic stem cells seems to be the best solution for the treatment of burn wounds. The main advantage of this method is obtaining a full sheet of cells by lowering the temperature below the transition temperature, which does not affect extracellular matrix.

Essential Partners for Student Health and Safety: Round Table Discussion With School Nurses and School Resource Officers.

This article explores the partnership between school nurses and school resource officers. Through an interviewing process, the authors summarize current examples of how the partnership is essential and effective in 21st-century schools across the United States.

On the Mechanisms of the Effects of Ionizing Radiation on Diblock and Random Copolymers of Poly(Lactic Acid) and Poly(Trimethylene Carbonate).

This article demonstrates that ionizing radiation induces simultaneous crosslinking and scission in poly(trimethylene carbonate--d-lactide) diblock and random copolymers. Copolymer films were electron-beam (EB) irradiated up to 300 kGy under anaerobic conditions and subsequently examined by evaluation of their structure (FT-IR, NMR), molecular weight, intrinsic viscosities, and thermal properties. Radiation chemistry of the copolymers is strongly influenced by the content of ester linkages of the lactide component.

Synthesis of papain nanoparticles by electron beam irradiation - A pathway for controlled enzyme crosslinking.

Crosslinked enzyme aggregates comprise more stable and highly concentrated enzymatic preparations of current biotechnological and biomedical relevance. This work reports the development of crosslinked nanosized papain aggregates using electron beam irradiation as an alternative route for controlled enzyme crosslinking. The nanoparticles were synthesized in phosphate buffer using various ethanol concentrations and electron beam irradiation doses.

Thermoresponsive poly[tri(ethylene glycol) monoethyl ether methacrylate]-peptide surfaces obtained by radiation grafting-synthesis and characterisation.

This report demonstrates the feasibility of radiation grafting for the preparation of polymer layers functionalised with short peptide ligands which promote cell adhesion. Thermoresponsive poly [tri(ethylene glycol) monoethyl ether methacrylate] (PTEGMA) layers were synthesised on a polypropylene substrate by post-irradiation grafting. A cell adhesion moiety, the CF-IKVAVK peptide modified with a methacrylamide function and a fluorescent label were introduced to the surface during the polymerisation process.
