by Chayanee Noosak, Pavarish Jantorn, Jirut Meesane, Supayang Voravuthikunchai, Dennapa Saeloh Sericin, a natural protein from silk cocoon, has been reported for various biological properties in the biomaterials field. Modified forms of sericin have been studied for bone tissue engineering, while its unmodified form has been scarcely reported. Therefore, the purpose of this study was to evaluate physical and biological properties of unmodified sericin for potential use in bone surgery.

Lead toxicity accounts for 1.5% (900,000) of deaths annually in the world.

by Manel Boumegouas, Manjunath Raju, Joseph Gardiner, Neal Hammer, Yehia Saleh, Abdullah Al-Abcha, Apoorv Kalra, George S. Abela Background The interaction between pathogenic bacteria and cholesterol crystals (CCs) has not been investigated. However, CCs are found extensively in atherosclerotic plaques and sclerotic cardiac valves.

by Kuan-Wen Wang, Yoshiyuki Iizuka, Caroline Jackson Mineral soda alumina (m-Na-Al) glass is a common glass production group found around the Indo-Pacific region. In Iron Age Taiwan, its presence dates back to the early 1st millennium AD. This research discusses m-Na-Al glass beads excavated from Iron Age sites in Taiwan. No production sites for m-Na-Al have been found, but microstructural analysis suggests m-Na-Al glass appears to originate around South Asia and is exchanged widely.
