Increased Collagen Synthesis by Gingival Fibroblasts Derived from a Papillon-Lefevre Patient

Both skin and gingival fibroblasts in the Papillon-Lefévre patient synthesized Type I and Type III collagen in a ratio very similar to fibroblasts of control cells. The only abnormality appeared to be elevated levels of collagen and protein synthesis by gingival cells derived from the Papillon-Lefévre patient

Mapping conversations about new media: the theoretical field of digital communication

This article reflects on the current state of digital communication studies in the context of mass communication research. The objectives of the article are: 1) to characterize the enunciators and the contents of scientific conversations about digital communication; and 2) to sketch a map of possible interlocutors who might enrich this new research field. After quickly exploring the paradigms of mass communication studies, the article deals with the main theoretical conversations about digital communication. The second part of the article describes the transformations that the appearance of digital technology has generated in communication processes. The article concludes with an agenda of the main issues and partners that theoretical conversations about digital communication should include. The article analyzes the constitution of a new scientific field and describes the process that may, in the future, lead to the creation of a theory of digital communication
