Journal ArticleDOI
Effects of HEMA on water evaporation from water-HEMA mixtures.
TL;DR: The results indicate that as water evaporates from water-HEMA mixtures, the concentration of HEMA rises because it is relatively non-volatile, making it more difficult to remove the last amounts of water.
Journal ArticleDOI
Relating nickel-induced tissue inflammation to nickel release in vivo.
John C. Wataha,Norris L. O'Dell,Baldev B. Singh,Mohamed Ghazi,Gary M. Whitford,Petra E. Lockwood +5 more
TL;DR: The current study showed that the laser-ablation technique was well suited for the analysis of soft tissues for metal-ion content, and that the nickel distribution in tissues correlated well with overt tissue inflammation.
Journal ArticleDOI
Fatigue of Dental Ceramics in a Simulated Oral Environment
TL;DR: Lifetime prediction curves in 37°C water, constructed from the n-values and inert strengths, showed that fatigue failure within five years is a good possibility for feldspathic porcelain specimens at stress levels which can reasonably be anticipated to occur in the oral environment.
Journal ArticleDOI
Green Tea Polyphenol Causes Differential Oxidative Environments in Tumor versus Normal Epithelial Cells

TL;DR: It is concluded that pathways activated by GTPPs or EGCG in normal epithelial versus tumor cells create different oxidative environments, favoring either normal cell survival or tumor cell destruction, which may lead to applications of naturally occurring polyphenols to enhance the effectiveness of chemo/radiation therapy to promote cancer cell death while protecting normal cells.
Journal ArticleDOI
Ability of Ni-containing biomedical alloys to activate monocytes and endothelial cells in vitro.
TL;DR: In vitro results indicate that NiTi alloys pose a risk of promoting an inflammatory response in soft tissues by activating monocytes.
