The property of functional avidity is recognized to be of critical importance in determining pathogen clearance. An unresolved question with regard to this property is whether distinct naive subsets exist that display inherent differences in their peptide sensitivity requirements for activation, i.e., functional avidity, or whether differences in peptide sensitivity are induced following peptid...

Last year‘s COSIT, part of a conference series running (depending on who you ask) since 1992 or 1993, was held at the beautifully located Melbourne Business School at Mount Eliza, Victoria in September 2007. Official counting lists this conference as the 8th in line. It has been the first time that COSIT has taken place outside Europe and the USA. Still, with over 100 participants from all over...

power over nature, can work with natural means to effect cures. There is much that is theologically remarkable and psychologically astute, such as the description of the soul's desire for, and integral connection to, the body (chapter 4) or the account, which mingles physiological predisposition and psychological dynamic, of how anger rises from black bile (chapters 3.8 and 6.1). As Berger reco...

Acute Toxoplasma gondii infection in early pregnancy carries the risk of transmitting the infection to the fetus with serious sequelae. However, serological testing for IgG/IgM anti-Toxoplasma antibodies may fail to differentiate between a recent and past infection. Two hundred and twenty-four Kuwaiti women in their first trimester were screened for IgG/IgM antibodies by the Vitek Immuno Diagno...

OBJECTIVE Toxoplasma gondii infection, an intracellular parasite, is often asymptomatic or is caused by different clinical diseases without being detected. Evaluation of IgG, IgA, and IgM in order to diagnose the pending Toxoplasmosis may confront some problems. Several researches has showned that Toxo IgG avidity can be useful in the recent active Toxoplasmosis. In current study, modification ...

We present a novel approach for creating intelligent conversational agents based on a “schizophrenic” model implemented using the EVA (Evolutionary Virtual Agent) nano-agent architecture. The Ms House experiment developed using this approach is compared with Eliza and the Alice chatterbot.
