Recently, our laboratory demonstrated that Stat3 is required for the de novo development of chemically-induced skin tumors. We have further investigated the role of Stat3 in epithelial carcinogenesis using mice in which the expression of a constitutively active/dimerized form of Stat3 (Stat3C) is targeted to the proliferative compartment of epidermis(More)
In this paper, we present a spatial logic which can be used to reason about topological and spatial relationships among objects in spatial databases. The main advantages of such a formalism are its rigor-ousness, clear semantics and sound inference mechanism. We also show how the formalism can be extended to include orientation and metrical information.(More)
Aminoglycosides disrupt the outer membrane of Pseudomonas aeruginosa to facilitate access to their intracellular target. High-resolution X-ray micrography of live specimens is a relatively new technique. We used laser (nanosecond) plasma to image live cells of P. aeruginosa ATCC 27853. After exposure to 25 mg/L gentamicin for 15 min. we observed(More)
A common tool in studying the structure and function of major histocompatibility complex: (MHC) class I is the generation and analysis of beta2-microglobulin (beta2m) mutations. beta2m has been shown to affect proper class I antigen presentation at the level of structural functionality. Many studies characterizing beta2m function in class I presentation(More)
Twelve indole derivatives have been prepared and studied. Five were 1-substituted: 1, methyl; 2, n-hexyl; 3, n-octyl; 4, n-octadecyl; and 5, cholestanyloxycarbonylmethyl. Four were 3-substituted: 6, methyl; 7, n-hexyl; 8, n-octyl; and 9, n-octadecyl. Three were disubstituted as follows: 10, 1-n-decyl-3- n-decyl; 11, 1-methyl-3-n-decyl; and 12,(More)
