Transendothelial migration of neutrophils involves integrin-associated protein (CD47).

Inflammation is a primary pathological process. The development of an inflammatory reaction involves the movement of white blood cells through the endothelial lining of blood vessels into tissues. This process of transendothelial cell migration of neutrophils has been shown to involve neutrophil beta 2 integrins (CD18) and endothelial cell platelet-endothelium cell adhesion molecules (PECAM-1; CD31). We now show that F(ab')2 fragments of the monoclonal antibody B6H12 against integrin-associated protein (IAP) blocks the transendothelial migration of neutrophils stimulated by an exogenous gradient of the chemokine interleukin 8 (IL-8; 60% inhibition), by the chemotactic peptide N-formyl-methionylleucylphenylalanine (FMLP; 76% inhibition), or by the activation of the endothelium by the cytokine tumor necrosis factor alpha (98% inhibition). The antibody has two mechanisms of action: on neutrophils it prevents the chemotactic response to IL-8 and FMLP, and on endothelium it prevents an unknown but IL-8-independent process. Blocking antibodies to IAP do not alter the expression of adhesion proteins or production of IL-8 by endothelial cells, and thus the inhibition of neutrophil transendothelial migration is selective. These data implicate IAP as the third molecule essential for neutrophil migration through endothelium into sites of inflammation.

Theory of Systems, Systems Metaphysics and Neoplatonism

Science has been developed from the rational-empirical methods, having as a consequence, the representation of existing phenomena without understanding the root causes. The question which currently has is the sense of the being, and in a simplified way, one can say that the dogmatic religion lead to misinterpretations, the empirical sciences contain the exact rational representations of phenomena. Thus, Science has been able to get rid of the dogmatic religion. The project for the sciences of being looks to return to reality its essential foundations; under the plan of theory of systems necessarily involves a search for the meaning of Reality.

The migration of Ukrainians in times of crisis. OSW COMMENTARY Number 187, 2015-10-19

Before the Russian annexation of Crimea and the outbreak of the conflict in eastern Ukraine, the scale of labour outward migration of Ukrainians had been characterised by a slight downward trend. Back in 2014, an increase in the number of Ukrainians who migrated to Russia was observed, although no similar increase was recorded for EU countries (excluding Poland). The year 2015 brought a more rapid surge in the number of Ukrainians migrating to the EU, again mainly to Poland. Due to the lack of current EU-wide data, estimates can be made based only on data compiled by national statistical offices in countries which are the most popular with Ukrainian migrants. In Poland, as of October 2015 Ukrainians held 52,000 valid residence cards. Much greater migration dynamics have been observed in the case of temporary migration – the number of declarations which enable an individual to take up a temporary job in Poland, issued in the first half of 2015, was a staggering 400,000. This means a more than twofold increase – in the whole of 2014 372,000 declarations were issued to Ukrainian citizens. No similar increase has so far been observed in other EU states, including Italy and the Czech Republic, which have always been popular destinations for Ukrainian migration. In late 2014, 233,000 Ukrainian migrants were registered in Italy (in late 2013 the figure was 191,000), whereas in the Czech Republic the number of Ukrainian migrants remains stable – 104,000 in June 2015.
