Example Sentences:

(2) We therefore conclude that the protective effect displayed by solid grafts might be a local process dependent on the release of diffusible trophic agents.
(3) The flounder developed renal and pancreatic neoplasms and hepatotoxic neoplastic precursor lesions, demonstrating trophic transfer of sediment-bound carcinogens up the food chain.
(4) Taken together, our results have demonstrated direct trophic effects of RA on spinal cord neurons and have suggested another role for astrocytes in the maintenance of normal neural physiology by regulating RA concentrations through the oxidation of retinol.
(5) Under conditions of disturbed blood supply, irrespective of the method of anastomosing, the trophicity of tissues in the zone of suture is sharply disturbed.
(6) The transformations described are interpreted as a response of the immune system to the nerve cut, and as a result of it--denervation of the crural tissues, disturbance of their nervous trophic, as well as--to transplantation of the allogeneic nervous trunk.
