Journal ArticleDOI
Matrix metalloproteinases induction by pseudomonal virulence factors and inflammatory cytokines in vitro.
Seiya Miyajima,Takaaki Akaike,Koki Matsumoto,Tatsuya Okamoto,Jun Yoshitake,Kazuyuki Hayashida,Akira Negi,Hiroshi Maeda +7 more
TL;DR: Corneal destruction seen with P. aeruginosa infections may result from enhanced expression of MMPs by corneal stromal cells stimulated with pseudomonal exoproteases and proinflammatory cytokines and the proteolytic activation of M MPs by Pseudomonal elastase.
Journal ArticleDOI
Chemical modification of superoxide dismutase. Extension of plasma half life of the enzyme through its reversible binding to the circulating albumin
TL;DR: In vivo analysis revealed that intravenously administered SMA-SOD circulated bound to albumin with an extremely long half-life (6 h), while unmodified SOD rapidly underwent renal glomerular filtration with a plasma half- life of 4 min, suggesting that SMA -SOD may effectively dismutase superoxide radicals in the circulation.
Journal ArticleDOI
Nitric Oxide as an Endogenous Mutagen for Sendai Virus without Antiviral Activity
Jun Yoshitake,Takaaki Akaike,Teruo Akuta,Fumio Tamura,Tsutomu Ogura,Hiroyasu Esumi,Hiroshi Maeda +6 more
TL;DR: The results indicate unambiguously that NO has mutagenic potential for RNA viruses such as Sendai virus without affecting viral replication, possibly via 8-nitroguanosine formation and cellular oxidative stress.
Journal ArticleDOI
Role of peroxynitrite in airway microvascular hyperpermeability during late allergic phase in guinea pigs.
Hisatoshi Sugiura,Masakazu Ichinose,Tatsuya Oyake,Y Mashito,Yuzuru Ohuchi,Naomi Endoh,Motohiko Miura,Shunsuke Yamagata,Akira Koarai,Takaaki Akaike,Hiroshi Maeda,Kunio Shirato +11 more
TL;DR: The results suggest that excessive production of O(2)(-) and NO occurs in the late allergic response (LAR) in sensitized guinea pigs in vivo, and these two molecules appear to cause airway microvascular hyperpermeability via peroxynitrite formation.
Journal ArticleDOI
The serratial 56K protease as a major pathogenic factor in serratial keratitis. Clinical and experimental study.
TL;DR: In this article, two strains of Serratia marcescens were isolated: one from a patient with severe liquefactive keratitis, who had diabetes mellitus, and one from an individual with mild superficial keratitis but who had no underlying disease.
