Visible Light Cured Thiol-vinyl Hydrogels with Tunable Gelation and Degradation
Hydrogels Visible light photopolymerization Tissue engineering
2015/1/12
Hydrogels prepared from photopolymerization have been widely used in many biomedical applications. Ultraviolet (200-400 nm) or visible (400-800 nm) light can interact with light-sensitive compounds ca...
Small-Molecule Hydrophobic Tagging Induced Degradation of HaloTag Fusion Proteins
Degradation of HaloTag Fusion Proteins Small-Molecule Hydrophobic Tagging
2014/11/25
The ability to regulate any protein of interest in living systems with small molecules remains a challenge. We hypothesized that appending a hydrophobic moiety to the surface of a protein would mimic ...
Susceptibility of methacrylate-based root canal filling to degradation by bacteria found in endodontic infections
clear zone degradation endodontic bacteria Resilon
2014/11/6
Objectives: To present a case of endodontic failure obturated with a methacrylate-based root filling material, Resilon/ RealSeal (RS). To determine if RS is susceptible to biodegradation by endodontic...
Changes in Microfungal Community in Cherrapunji—The Wettest Patch on Earth as Influenced by Heavy Rain and Soil Degradation
