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...

Rhodopsin is a 7-helix, integral membrane protein found in the rod outer segments, which serves as the light receptor in vision. Light absorption by the retinylidene chromophore of rhodopsin triggers an 11-cis-->all-trans isomerization, followed by a series of protein conformational changes, which culminate in the binding and activation of the G-protein transducin by the metarhodopsin II (Meta ...
متن کاملSignaling states of rhodopsin. Formation of the storage form, metarhodopsin III, from active metarhodopsin II.
Vertebrate rhodopsin consists of the apoprotein opsin and the chromophore 11-cis-retinal covalently linked via a protonated Schiff base. Upon photoisomerization of the chromophore to all-trans-retinal, the retinylidene linkage hydrolyzes, and all-trans-retinal dissociates from opsin. The pigment is eventually restored by recombining with enzymatically produced 11-cis-retinal. All-trans-retinal ...

The absorption of glutamic acid and glutamine.
The occurrence of free glutamine in plant tissue extracts has been recognized for a considerable time, but its presence in the protein-free filtrates of mammalian tissues was established only recently (1). The functional significance of the free amide in tissues cannot be appreciated without a knowledge of its quantitative relationship to glutamic acid and of the biological mechanisms regulatin...
