Hydrogels that solidify in response to a dual, physical and chemical, mechanism upon temperature increase were fabricated and characterized. The hydrogels were based on N-isopropylacrylamide, which renders them thermoresponsive, and contained covalently cross-linkable moieties in the macromers. The effects of the macromer end group, acrylate or(More)
Background Increasing the nasolabial angle (NLA) with tip rotation generates the appearance of a lengthened lower facial third. In particular, the upper lip show seems increased following elevation of the nasal tip. Objectives The purpose of this study is to quantify the impact of tip rotation on upper lip length (ULL), and to establish a predictable(More)
The discovery of structured non-coding RNAs (ncRNAs) in bacteria can reveal new facets of biology and biochemistry. Comparative genomics analyses executed by powerful computer algorithms have successfully been used to uncover many novel bacterial ncRNA classes in recent years. However, this general search strategy favors the discovery of more common ncRNA(More)
