The purpose of the present study was to investigate the protective effect and mechanism of chitosan oligonucleotides (COS) on retinal ischemia and reperfusion (I/R) injury. Rats pretreated with PBS, low-dose COS (5 mg/kg), or high-dose COS (10 mg/kg) were subjected to retinal ischemia by increasing their intraocular pressure to 130 mm Hg for 60 min. The(More)
To analyze the influence of spectral-domain optical coherence tomography (SD-OCT) features on visual acuity changes in patients with idiopathic epiretinal membranes (ERMs). Seventy-nine eyes of 71 patients were included in this study. SD-OCT was performed for all patients; data were collected upon ERM diagnosis and at the final visit. The patients were(More)
High linoleic acid (LA) intake is known to correlate with age-related macular degeneration (AMD), but the molecular mechanisms remain unclear. This study was conducted to investigate the effects of LA on expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase II (COX-2) and their associated signaling pathways in human retinal pigment(More)
We investigated the protective effects and mechanisms of chitosan oligosaccharides (COS) on experimental autoimmune anterior uveitis (EAAU) in rats. EAAU was induced in Lewis rats by footpad and intraperitoneal injections of melanin-associated antigen. The rats received intraperitoneal injections of low-dose (5 mg/kg) or high-dose (10 mg/kg) COS or PBS(More)
Induced pluripotent stem cells (iPSC) are novel stem cell populations, but the role of iPSC in retinal ischemia and reperfusion (I/R) injury remains unknown. Since oncogene c-Myc is substantially contributed to tumor formation, in this study, we investigated the effects, mechanisms and safety of subretinal transplantation of iPSC without c-Myc (non-c-Myc(More)
Transplantation of retinal pigment epithelium (RPE) following removal of choroidal neovascular membranes has been attempted in patients with age-related macular degeneration (AMD). However, inability of transplanted RPE to initially attach and subsequently proliferate on Bruch's membrane may lead to failure of RPE transplants and poor visual outcomes.(More)
Differentiation of totipotent mouse embryonic stem (ES) cells to various lymphohematopoietic cells is an in vitro model of the hematopoietic cell development during embryogenesis. To understand this process at cellular levels, differentiation intermediates were investigated. ES cells generated progeny expressing CD34, which was significantly enhanced by(More)
The purpose of this study is to investigate the sequential expression of certain chemokines and chemokine receptors in the iris-ciliary body and popliteal lymph nodes of Lewis rats and, thus, to establish their roles in experimental autoimmune anterior uveitis. Uveitis was induced with the injection of melanin-associated antigen intraperitoneally and into(More)
PURPOSE To demonstrate the expression and location of CX3C chemokine, fractalkine, and its receptor, CX3CR1, in the iris/ciliary body and thus establish their roles in experimental autoimmune anterior uveitis, an animal model of human acute anterior uveitis. METHODS Uveitis was induced in Lewis rats by injection of melanin associated antigen into the(More)
PURPOSE To determine the effect of pyrrolidine dithiocarbamate (PDTC), a nuclear factor (NF)-kappaB inhibitor, on chemokine and chemokine receptor expression and thus elucidate the role of NF-kappaB in the pathogenesis of experimental autoimmune anterior uveitis (EAAU). METHODS Uveitis was induced in Lewis rats with the injection of melanin-associated(More)
