The ability of nickel sulphate and potassium dichromate to induce contact sensitization in mice has been investigated. Topical exposure of mice to 0.5% potassium dichromate in dimethylsulphoxide (DMSO) under occlusion resulted in specific contact sensitization in each of 7 experiments. Although sensitization to nickel sulphate under the same conditions was(More)
Exogenous administration of pineal hormone melatonin (MEL) has been demonstrated to attenuate organ damage in models of I/R and inflammation by antioxidative effects. However, specific organ-protective effects of MEL with respect to hemorrhagic shock have not been investigated yet. In the present study, we evaluated the role of MEL pretreatment for hepatic(More)
OBJECTIVE Melatonin has been demonstrated to attenuate organ damage in models of ischemia and reperfusion. Melatonin treatment before hemorrhagic shock has been shown to improve liver function and hepatic perfusion. Proposed mechanisms of the pineal hormone involve direct inactivation of reactive oxygen species and induction of antioxidative enzymes.(More)
Two different approaches to the interrogation of prokaryotic and eukaryotic cells have been explored, with the objective of developing biosensor based rapid ecotoxicity test protocols for use in a wide range of applications. Prokaryotic cells and some eukaryotic cell types lend themselves to interrogation by mediated amperometry, a technique that allows(More)
Michael Schiffer’s theoretical and methodological contributions to archaeology are substantial. For the last two decades, Schiffer has become increasingly interested in the history of electrical technology, including portable radios, electric automobiles, eighteenth-century electrostatic technology, and, most recently, nineteenth-century electric light and(More)
2,4,6-Trinitrochlorobenzene (picryl chloride) and 2,4-dinitrochlorobenzene (DNCB) fail to cross-sensitize with respect to contact sensitivity in mice. Nevertheless, topical exposure of mice to DNCB and other skin-sensitizing dinitrobenzene derivatives was found to result in a significant impairment of draining lymph node cell proliferative responses induced(More)
Perhaps the one theoretical position available to archaeologists today that has the potential to integrate culture history, processualism, and post-processualism is the study of complexity and complex systems. Not to be confused with political complexity and the rise of social hierarchies, complexity theory is the study of how new complex properties emerge(More)
The requirements for the induction of antigenic competition in murine contact sensitivity have been examined. Experiments with a variety of skin-sensitizing chemicals revealed a correlation between immunogenicity and the ability to inhibit subsequent responses to an unrelated contact allergen, oxazolone. Previous studies have suggested that, in contact(More)
