interpersonal function of language in subtitling
translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
15 صفحه اولChemotactic peptide receptor modulation in polymorphonuclear leukocytes
The binding of the chemotactic peptide N-formylnorleucylleucylphenylalanine (FNLLP) to its receptor on rabbit polymorphonuclear leukocytes (PMNs) modulates the number of available peptide receptors. Incubation with FNLLP decreases subsequent binding capacity, a phenomenon that has been termed receptor down regulation. Down regulation of the chemotactic peptide receptor is concentration dependen...
متن کاملSensory adaptation of leukocytes to chemotactic peptides
The morphology and behavior of polymorphonuclear leukocytes (PMNs) were studied after rapid changes in the concentration of a chemotactic factor N-formylnorleucylleucylphenylalanine (f-NorleuLeuPhe) (Schiffmann et al., 1975, Proc. Natl. Acad. Sci. U. S. A. 72:1059--1062). After an increase in peptide concentration, the cells round, form lamellipodia or ruffles over most of their surface, and st...
متن کاملStudy of telomerase activity, proliferation and differentiation characteristics in umbilical cord blood mesenchymal stem cells
In recent years, considerable advances have been made in the field of regenerative medicine. Unlikeembryonic stem cells, which pose the problems of ethical concerns and cause severe immunological reactions as well as neoplasma formation after transplantation, umbilical cord blood is a primitive source ofmesenchymal stem cells that covers the benefits of both embryonic and adult stem cells. It h...
متن کاملPertussis toxin inhibition of chemotactic factor-induced calcium mobilization and function in human polymorphonuclear leukocytes
Chemotactic factors stimulate a rapid increase in the cytosolic concentration of intracellular calcium ions ([Ca2+]in) in human polymorphonuclear leukocytes (PMNL), which may be an event that is critical to the expression of chemotaxis and other PMNL functions. Treatment of PMNL with pertussis toxin catalyzes ADP-ribosylation of a protein similar or identical to the inhibiting regulatory protei...
