| 1 | Nanofibrous nerve conduits for repair of 30-mm-long sciatic nerve defects显示文摘It has been confirmed that nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) nerve conduit can promote peripheral nerve regeneration in rats. However, its efficiency in repair of over 30-mm-long sciatic nerve defects needs to be assessed. In this study, we used a nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) nerve conduit to bridge a 30-mm-long gap in the rat sciatic nerve. At 4 months after nerve conduit implantation, regenerated nerves were macroscopically observed and histologically assessed. In the nanofibrous graft, the rat sciatic nerve trunk had been reconstructed by restoration of nerve continuity and formation of myelinated nerve fiber. There were Schwann cells and glial cells in the regenerated nerves. Masson's trichrome staining showed that there were no pathological changes in the size and structure of gastrocnemius muscle cells on the operated side of rats. These findings suggest that nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) nerve conduit is suitable for repair of long-segment sciatic nerve defects. | Esmaeil Biazar Saeed Heidari Keshel Majid Pouya Hadi Rad Melody Omrani Nava Mohammad Azarbakhsh Shirin Hooshmand | 2013 | Neural Regeneration Research2013，8，24： | 1 |
| 2 | Assessing the Role of Environmental Factors in the Transmission of Infectious Diseases in Communal Spaces显示文摘Communal spaces provide different facilities for users while they are the primary place for the spread of diseases,especially respiratory.Transmission is possible through human behaviors,the way they communicate with each other and breathe in an environment by airborne pathogenic particles.Experts from various fields have gained valuable experience and achievements regarding how to prevent these diseases by means of environmental factors.Due to the spread of the corona virus in the past years,environmental planners and designers seriously considered the need to review the design and use of spatial components.This study provides a framework for decision making and design of communal spaces based on how environmental components can be effective in preventing the spread of respiratory diseases such as coronavirus and influenza.The research method used in this article is logical reasoning combined with ANP method and focus group discussion.According to the results of this research,indoor air quality plays the most crucial role in preventing the transmission of viruses(contagious respiratory diseases)based on expert groups. | Seyyed Mohammadmahdi Hosseinikia Negar Khiabanchian Hadi Rezaei Rad | 2023 | Journal of Architectural Environment & Structural Engineering Research2023，6，2： | 0 |
