Journal ArticleDOI
Chitosan preparations for wounds and burns: antimicrobial and wound-healing effects
TL;DR: The antimicrobial and wound-healing effects of chitosan, as well as its derivatives and complexes, and its use as a vehicle to deliver biopharmaceuticals, antimicrobials and growth factors into tissue are covered.
Journal ArticleDOI
Type I and Type II mechanisms of antimicrobial photodynamic therapy: An in vitro study on Gram-negative and Gram-positive bacteria
Liyi Huang,Yi Xuan,Yi Xuan,Yuichiro Koide,Yuichiro Koide,Timur Zhiyentayev,Timur Zhiyentayev,Masamitsu Tanaka,Masamitsu Tanaka,Michael R. Hamblin +9 more
TL;DR: This study examined the relative contributions of 1O2 and HO.
Journal ArticleDOI
Animal models of external traumatic wound infections.
Tianhong Dai,Gitika B. Kharkwal,Masamitsu Tanaka,Ying-Ying Huang,Vida J. Bil de Arce,Michael R. Hamblin +5 more
TL;DR: As antibiotic resistance continues to increase, more new antimicrobial approaches are urgently needed and these should be tested using standard protocols for infections in external traumatic wounds in animal models.
Journal ArticleDOI
Paradoxical potentiation of methylene blue-mediated antimicrobial photodynamic inactivation by sodium azide: Role of ambient oxygen and azide radicals
Liyi Huang,Tyler G. St. Denis,Tyler G. St. Denis,Yi Xuan,Yi Xuan,Ying-Ying Huang,Ying-Ying Huang,Masamitsu Tanaka,Masamitsu Tanaka,Andrzej Zadlo,Tadeusz Sarna,Michael R. Hamblin +11 more
TL;DR: It was found that N(3)() was formed and bacteria were killed even in the absence of oxygen, suggesting the direct one-electron oxidation of azide anion by photoexcited MB, which suggests a possible mechanism to carry out oxygen-independent PDT.
Journal ArticleDOI
Optimal Photosensitizers for Photodynamic Therapy of Infections Should Kill Bacteria but Spare Neutrophils
Masamitsu Tanaka,Manabu Kinoshita,Yasuo Yoshihara,Nariyoshi Shinomiya,Shuhji Seki,Koichi Nemoto,Takahiro Hirayama,Tianhong Dai,Liyi Huang,Michael R. Hamblin,Michael R. Hamblin,Yuji Morimoto +11 more
TL;DR: It is suggested that PDT using TB or MB can preserve host neutrophils while exerting a significant therapeutic effect on in vivo localized microbial infection.
