Abstract
Nanotechnology and tissue engineering are promising scientific fields in the development of advanced materials useful to human health. This article describes the preparation of a nanocarrier for the controlled release of a photosensitizer compound associated with low-level light therapy for skin wound healing treatment and applicable to other skin diseases. A biological model was used as an in vitro skin equivalent based on a three-dimensional culture of fibroblasts and mesenchymal stem cells and denominated by dermal equivalent (DE). Results show that it is possible to use the photomodulation process to control the wound healing in a scratching process and to induce the biomolecules release, both of which are related with the inflammatory wound healing process. In the studies, the MMP-2 and MMP-9 expression from zymography analyses were evaluated. All results showed a dependence on enzymatic activity relating to lowlevel laser applications which indicates a potential application in wound healing processes based on phototherapy and nanotechnology.

Chalcogen-modified nucleic acid analogues
Chalcogen-modified nucleosides, nucleotides and oligonucleotides have been of great interest to scientific research for many years. The replacement of oxygen in the nucleobase, sugar or phosphate backbone by chalcogen atoms (sulfur, selenium, tellurium) gives these biomolecules unique properties resulting from their altered physical and chemical properties. The continuing interest in ...read more
