Toxicological Profile for Ethylbenzene

Disproportionation of Ethylbenzene over Sapo-40

SAPO-40, a silicoaluminophosphate with a structure not topologically related with any aluminosilicate zeolite, was synthesised for the first time in 1984 by Lok and co-workers [1]. Recently, a synthesis procedure leading to pure SAPO40 was developed and the structure of this material was established by crystallographic methods. The framework topology (designated AFR by the International Zeolite...

Clarifying Utterances

The paper argues for the importance of utterances (as opposed to \sen-tences in context") as basic units in dialogue. The main case study is clar-iication: a characterization is provided within KOS, a recently developed synthesis of situation semantics and dialogue games, of the clariications that can follow up on an utterance. This involves outlining: (a) a theory of understanding for dialogue...

Carcinogenicity and Anti-tumoral Effect of Parasites: A Review Study

In endemic areas, some parasitic infections may be related to cancer induction or induction of immune responses against cancer. In some cases, parasites cause disease in their host, and in other cases, they reach a biological balance with them. Parasite invasion of the host depends on some factors such as parasite species, life cycle, enzyme production, and host immunity. The results of various...

Mechanism of ethylbenzene-induced mouse-specific lung tumor: metabolism of ethylbenzene by rat, mouse, and human liver and lung microsomes.

This study was conducted to determine species differences in the metabolism of ethylbenzene (EB) in liver and lung. EB (0.22-7.0mM) was incubated with mouse, rat and human liver and lung microsomes and the formation of 1-phenylethanol (1PE), acetophenone (AcPh), 2-ethylphenol (2EP), 4-ethylphenol (4EP), 2,5-ethylquinone, and 3,4-ethylquinone were measured. Reactive metabolites (2,5-dihydroxyeth...
