and P03-01). We are indebted to our research team members Jason Fong, Yaqiang Qi, and Emre Uyar. Nanotechnology data used in this paper is part of NanoBank.org, a community resource building project funded by NSF. In this paper, we both introduce and demonstrate some of the potential uses for this new database, as well as test the underlying data in(More)
What are middle school students' attitudes toward digital cheating and plagiarism? To answer the question, an empirical study was conducted in three middle schools using multiple focus groups and interviews. Students participated in the focus groups, and teachers, and parents participated in interviews. The study found that peer culture contributed to the(More)
Anthocyanins are a class of naturally occurring polyphenols which have been most widely studied in recent decades for the rapid development of relative techniques. This article first reviews the various anthocyanin resources including fruits, flowers, vegetables and beverages. Besides the direct extraction from natural resources, anthocyanins can also be(More)
Melon, Cucumis melo L. is an important vegetable crop worldwide. At present, there are phenomena of homonyms and synonyms present in the melon seed markets of China, which could cause variety authenticity issues influencing the process of melon breeding, production, marketing and other aspects. Molecular markers, especially microsatellites or simple(More)
To better engineer and analyze beneficial biofilms as well as to develop strategies to control detrimental biofilms (e.g., biomedical device-based infections), it is critical to quantify bacterial species compositions within biofilms. A non-invasive method is described here that determines local and overall bacterial concentrations within a biofilm, using(More)
Staphylococcus epidermidis is an opportunistic bacterium that thrives as a commensal cutaneous organism and as a vascular pathogen. The S. epidermidis extracellular matrix binding protein (Embp) has been reported to be a virulence factor involved in colonization of medical device implants and subsequent biofilm formation. Here, we characterize the(More)
Macrophage migration inhibitory factor (MIF) is up-regulated in diverse solid tumors and acts as the critical link between immune response and tumorigenesis. In this study, we demonstrated that MIF overexpression promoted migration of breast cancer cells by elevating TLR4 expression. Further investigation evidenced that MIF induced ROS generation.(More)
BACKGROUND The role of low-dose hydrocortisone in attenuating septic shock and reducing short-term mortality in adult patients with septic shock is unclear. We conducted a meta-analysis of previous studies to determine whether hydrocortisone could ameliorate the effects of septic shock at 7 and 28 days and reduce 28-day morality. METHODS Randomized(More)
Traditional antibiotic therapy to control medical device-based infections typically fails to clear biofilm infections and may even promote the evolution of antibiotic resistant species. We report here the development of two novel antibiofilm agents; gallium (Ga) or zinc (Zn) complexed with protoporphyrin IX (PP) or mesoprotoporphyrin IX (MP) that are both(More)
