PURPOSE The aim of this study was to evaluate the relationship, if any, between pesticide exposure and overexpression of the HER-2/neu oncoprotein in extensive stage small cell lung cancer (ESSCLC). EXPERIMENTAL DESIGN The records of all patients with a diagnosis of ESSCLC from January 1991 through April 2001 were reviewed in our retrospective study. Pesticide risk (herbicide and insecticide)...

A set C can be strongly coded under condition < B, C(A) >, where B and C are classes of sets possibly with other parameters, iff there exists A ∈ B such that every Z ∈ C(A) can be used to compute C. The issue is widely studied especially in effective mathematics and reverse mathematics. In this paper, we focus on three kinds of conditions, namely, density condition, enumeration condition and pa...

A bstract We show that barotropic flows of a perfect, charged, classical fluid exhibit an anomaly analogous to the chiral known in quantum field theories with Dirac fermions. prominent effect is transport electric current at equilibrium reservoir. find it also property celebrated Beltrami — stationary solutions Euler equation extensive helicity.

This Article offers an explanation of the role of intellectual property rights (IPRs) in information-intensive vertical supply relationships. In particular, we explore the connection between stronger property rights and the enhanced viability of independent (versus vertically integrated) input supply firms when contracts are incomplete. We start by modeling a tradeoff between two types of infor...

Focal epithelial hyperplasia (FEH) or Heck’s disease is a rare viral infection of the oral mucosa caused by human papilloma virus especially subtypes 13 or 32. The frequency of this disease varies widely from one geographic region and ethnic groups to another. This paper reports an Iranian case of extensive focal epithelial hyperplasia. A 35-year-old man with FEH is described, in whom the lesio...

Does extensive practice reduce or eliminate central interference in dual-task processing? We explored the reorganization of task architecture with practice by combining interference analysis (delays in dual-task experiment) and random-walk models of decision making (measuring the decision and non-decision contributions to RT). The main delay observed in the Psychologically Refractory Period at ...
