Starch-based antibacterial food packaging with ZnO nanoparticle.

Unlabelled: Starch-based biofilms with embedded nanoparticles (NPs) are used to wrap food in biodegradable packaging system that has high antibacterial action against a variety of microorganisms. In this study, ZnO NPs were synthesised using both a green synthesis approach utilising (Neem) and a chemical synthesis approach using the sol-gel technique. The structural and morphological properties of all synthesized NPs were characterized through XRD, UV-VIS, UV-DRS, FTIR, and FESEM analysis.

Optimum sevoflurane concentration for I-gel insertion in unpremedicated children.

Study Objective: End-tidal concentration of sevoflurane for I-gel insertion in children has not been studied. This study was designed to determine the sevoflurane EC50 and EC95 for I-gel placement in children as compared with classic laryngeal mask airway (CLMA) placement.

Design: The design was a prospective, randomized controlled study.
