After 4K, 8K UHD resolution can be considered the new challenge for film, visualization and television. Due to the dimension of 8K image, the remote micro and macro images are considered appropriate for visualization with scientific and educational purposes. This article describes the implementation of the 8K video plug-in to play UHD videos into the SAGE, a collaborative environment for the advancement of scientific research and education developed by EVL (Electronic Visualization Laboratory), upgrading its current resolution for video playing. It also presents the challenges of producing 8K content, the development of the code and introduces the features to view 8K ultra high definition videos in multiple tiles through the use of low cost computer clusters. The SAGE 8K video plug-in implementation was made possible because of the previous development of the Fogo Player, a system to run 4K and 8K content. The results were successfully presented at the CineGrid International Workshop 2013 in San Diego.

Background: In recent years, so-called “non-ablative rejuvenation” has been carried out with the use of lasers or intense pulsed light (IPL) to stimulate collagen production by dermal fibroblasts. Intradermal infusion of CO2 stimulates fibroblasts and the synthesis of collagen and elastin, contributing to the retraction of the skin and tissue rejuvenation. Objectives: To evaluate the effects of IPL and the intradermal infusion of CO2 on fibroblast proliferation and collagen in the skin of female rats. Methods: Sixteen adult female Wistar rats were divided into two groups of eight animals. Group 1 underwent IPL and group 2 underwent intradermal CO2 infusion. There was a total of 8 weeks of treatment. We conducted a punch in each animal before any procedure (T0), another punch in the middle of treatment at 4 weeks post-procedure (T1) and a punch at the end of treatment at 8 weeks post-procedure (T2). The cells involved in inflammation, fibrosis and vascularization of the injured tissue by histopathology were analyzed. Results: There was statistically significant fibroblast proliferation and collagen proliferation noted when analyzing all 16 animals together and also when considering the two study groups separately. In both groups, the greatest proliferation of fibroblasts coincided with periods of increased collagen production. Conclusion: Both IPL and intradermal CO2 infusion stimulated fibroblast and collagen proliferation in the skin of the rats studied.
