| 1 | Photodynamic therapy guidelines for the management of oral leucoplakia显示文摘With recent developments in photosensitizers and light delivery systems,topical 5-aminolevulinic acid-mediated photodynamic therapy (ALA-PDT) has become the fourth alternative therapeutic approach in the management of oral leucoplakia (OLK) due to its minimally invasive nature,efficacy,and low risk of systemic side effects and disfigurement.This report presents step-by-step guidelines for applying topical ALA-PDT in the management of OLK based on both the clinical experience of the authors and a systematic review of the current literature.Studies using protocols with standardized parameters and randomized clinical trials at multiple centres with adequate sample sizes and both interim and long-term follow-ups are needed before universally applicable guidelines can be produced in this field. | Qianming Chen Hongxia Dan Fan Tang Jiongke Wang Xiaoying Li Junxin Cheng Hang Zhao Xin Zeng | 2019 | International Journal of Oral Science2019，11，2： | 18 |
| 2 | Dynamic photoelectrical regulation of ECM protein and cellular behaviors显示文摘Dynamic regulation of cell-extracellular matrix(ECM)-material interactions is crucial for various biomedical applications.In this study,a light-activated molecular switch for the modulation of cell attachment/detachment behaviors was established on monolayer graphene(Gr)/n-type Silicon substrates(Gr/Si).Initiated by light illumination at the Gr/Si interface,pre-adsorbed proteins(bovine serum albumin,ECM proteins collagen-1,and fibronectin)underwent protonation to achieve negative charge transfer to Gr films(n-doping)throughπ-πinteractions.This n-doping process stimulated the conformational switches of ECM proteins.The structural alterations in these ECM interactors significantly reduced the specificity of the cell surface receptor-ligand interaction(e.g.,integrin recognition),leading to dynamic regulation of cell adhesion and eventual cell detachment.RNA-sequencing results revealed that the detached bone marrow mesenchymal stromal cell sheets from the Gr/Si system manifested regulated immunoregulatory properties and enhanced osteogenic differentiation,implying their potential application in bone tissue regeneration.This work not only provides a fast and feasible method for controllable cells/cell sheets harvesting but also gives new insights into the understanding of cell-ECM-material communications. | Xiaozhao Wang Cai Yao Xudong Yao Junxin Lin Rui Li Kun Huang Weiming Lin Xiaojun Long Chao Dai Jiajun Dong Xuegong Yu a Wenwen Huang Wenjian Weng Qi Wang Hongwei Ouyang Kui Cheng | 2023 | Bioactive Materials2023，，4： | 0 |
