Liu, G.; Bao, S.; Shi, J.; Xie, C.; Liao, F.; Wang, L.; Zheng, F.; Reis, R. L.; Kundu, Subhas C; Xiao, B.; Yang, X.; Duan, L.Pathogenic bacterial invasion leads to severe inflammation that hinders wound healing, and it has become a major medical threat worldwide. Photodynamic therapy (PDT) has emerged as a promising strategy for treating microbial infection; however, developing a dressing with PDT effect and excellent biological functions poses a formidable challenge. Herein, a novel cationic pyrimidine-modified conjugated microporou...

Sirunyan, A. M.; Tumasyan, A.; Adam, W.; Ambrogi, F.; Asilar, E.; Bergauer, T.; Brandstetter, J.; Dragicevic, M.; Erö, J.; Escalante Del Valle, A.Made available in DSpace on 2022-04-28T19:11:08Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-09-17; The observation of the standard model (SM) Higgs boson decay to a pair of bottom quarks is presented. The main contribution to this result is from processes in which Higgs bosons are produced in association with a W or Z boson (VH), and are searched for in final states including 0, 1, or 2 charged lepto...
