background: asthma is a multifactorial disease and its severity varies with the inflammatory grade. there are conflicting reports about the roles of trace elements in asthma. this study examined the effects of zinc (zn), copper (cu), and selenium (se) concentrations in sera of patients with allergic asthma attending ghaem hospital, mashhad, iran. methods: forty-nine patients, aged 10 to 50 year...

background: the method of proton induced x-ray emission (pixe) has been widely used as a sensitive technique to trace elemental analysis in both biological and medical fields. the sensitivity of this powerful method is in the order of ppm .the aim of this work is to analyze structural composition of 4 heavy trace elements with z greater than 24 (mn, fe, cu, zn) in two kinds of gallstones and to...

We find a necessary and sufficient conditions for the simplicity and uniqueness of trace for reduced free products of finite families of finite dimensional C∗-algebras with specified traces on them.

We prove a version of the L2-index Theorem of Atiyah, which uses the universal center-valued trace instead of the standard trace. We construct for G-equivariant K-homology an equivariant Chern character, which is an isomorphism and lives over the ring Z ⊂ ΛG ⊂ Q obtained from the integers by inverting the orders of all finite subgroups of G. We use these two results to show that the Baum-Connes...

Haloperidol has been shown to enhance attentional selectivity in conditioning procedures. For example, in latent inhibition (LI) it improves animals' ability to treat as irrelevant, stimuli that have previously been presented without consequence. The present study tested whether this finding would generalize to other procedures that present animals with weak predictors. We therefore used a trac...

Biogeochemical interactions between a suite of trace elements and nutrients were examined in a series of experimental mesocosm experiments to understand how multiple stressors affect estuarine environments and how these effects are modified by the complexity of the system used to examine them. Experimental treatment included additions of nutrients and trace elements separately and combined, alo...
