Chemical warfare threats require the development of diverse models for the assessment of countermeasures. Human skin products, Skin2 (differentiating keratinocytes on a fibroblast-collagen matrix) and EpiDerm (differentiating keratinocytes) were exposed (2 h) to the sulfur mustard 2-chloroethyl ethyl sulfide (CEES, 1-2 mg l(-1) min(-1)) in humidified air or(More)
Ultrastructural and terminal deoxynucleotidyl transferase nick end labeling (TUNEL) studies were conducted to compare mechanisms of 2-chloroethyl ethyl sulfide (CEES) and heat-induced injury to EpiDerm. Twenty-two hours after 2-h exposure to the monofunctional alkylating agent CEES, budding of cytoplasm, clumping of nuclear chromatin, disintegration of(More)
Sulfur mustard provokes an acute inflammatory response in skin. To determine if keratinocytes regulate this response and whether three potential vesicant antagonists can counteract adverse changes, specimens of EpiDerm (MatTek Corp., Ashland, MA), a human skin model of differentiating keratinocytes, were exposed 2 h to humidified air with or without(More)
We discuss infinite zero-sum perfect-information games with more than two players. They are not determined in the traditional sense, but as soon as you fix a preference function for the players and assume common knowledge of rationality and this preference function among the players, you get determinacy for open and closed payoff sets. 2000 AMS Mathematics(More)
The P2Y(4) receptor is selectively targeted to the apical membrane in polarized epithelial cell lines and has been shown to play a key role in intestinal chloride secretion. In this study, we delimit a 23 amino acid sequence within the P2Y(4) receptor C-tail that directs its apical targeting. Using a mutagenesis approach, we found that four hydrophobic(More)
Generalized Catalan Numbers and Some Divisibility Properties by Jacob Bobrowski Dr. Peter Shiue, Examination Committee Chair Professor of Mathematical Sciences University of Nevada, Las Vegas I investigate the divisibility properties of generalized Catalan numbers by extending known results for ordinary Catalan numbers to their general case. First, I define(More)

Living skin equivalent (LSE) was used to identify nonvascular aspects of freeze-thaw injury to human skin cells. Pairs of transwell cell culture inserts, containing LSE, were washed twice for 30 min in maintenance media at 37 degrees C in a CO2 incubator and placed in two wells of a six-well assay tray (containing assay media). One specimen was maintained(More)
