PURPOSE Dogs fed a diet containing 30% galactose experience retinal vascular changes similar to those in human diabetic retinopathy, with selective pericyte loss as an initial lesion. In the present study the relationship among reduced nicotinamide adenine dinucleotide phosphate (NADPH)-dependent reductases, polyol formation, and flux through the polyol(More)
PURPOSE Vascular adhesion protein (VAP)-1, a multifunctional molecule with adhesive and enzymatic properties, is expressed at the surface of vascular endothelial cells of mammals. It also exists as a soluble form (sVAP-1), which is implicated in oxidative stress via its enzymatic activity. This study explores a link between increased level of sVAP-1 and(More)
PURPOSE Ultraviolet (UV) acts as low-dose ionizing radiation. Acute UVB exposure causes photokeratitis and induces apoptosis in corneal cells. Astaxanthin (AST) is a carotenoid, present in seafood, that has potential clinical applications due to its high antioxidant activity. In the present study, we examined whether topical administration of AST has(More)
PURPOSE To investigate the applicability of serine/arginine-rich protein kinase (SRPK)-specific inhibitor, SRPIN340, for attenuation of choroidal neovascularization (CNV) formation using a mouse model. METHODS Laser photocoagulation was performed to induce CNV in C57BL/6J mice, followed by intravitreal injection of SRPIN340 or vehicle. Seven days after(More)
PURPOSE A pterygium shows tumor-like characteristics, such as proliferation, invasion, and epithelial-mesenchymal transition (EMT). Previous reports suggest that tissue factor (TF) expression is closely related to the EMT of tumor cells, and subsequent tumor development. In this study, we analyzed the expression and immunolocalization of TF in pterygial and(More)
PURPOSE To investigate the alteration of vitreal N-glycans in patients with proliferative diabetic retinopathy (PDR). METHODS Plasma and vitreous samples were collected from 17 patients (10 females and 7 males) with PDR (PDR group) and 17 nondiabetic patients (8 females and 9 males) with epiretinal membrane (ERM) and idiopathic macular hole (MH)(More)
PURPOSE To investigate the antiangiogenic properties of tissue kallikrein in a murine model of laser-induced choroidal neovascularization (CNV). METHODS CNV was induced in male C57BL/6J mice by laser photocoagulation. The animals received daily subcutaneous injections of tissue kallikrein (50 μg/kg) or vehicle control for 2 days before the laser(More)
Vascular casts were made by injection of low-viscosity plastic in eight Wistar-Kyoto rats, and the posterior half of the ocular wall was observed using the semiultrathin section method. Veins which connect with the capillaries of the posterior choroid include a venous system independent of the cortex vein and running parallel to the long and short posterior(More)
