PURPOSE Doxifluridine (5'-deoxy 5-fluorouridine) is an oral anticancer drug with antiangiogenic effects, with vasoclastic action that is enhanced by a major member of the pyrimidine phosphorylases, thymidine phosphorylase (TP). Previous studies have demonstrated that TP is upregulated in the lesions where pathologic angiogenesis occurs and TP itself promotes angiogenesis. To investigate the pos...
The OCT angiograms showed reduced CNV flow area and CNV vessel loss following treatment. Because retinal vessel density did not decrease, reduced areas of CNV flow likely represent therapeutic effect. Optical coherence tomographic angiography can also be used to evaluate blood flow of the choriocapillaris. In healthy eyes, the choriocapillaris appears confluent on OCTangiograms.4 In this case, ...
We present a case of choroidal nevus, complicated by a choroidal neovascular membrane (CNV) that was detected by OCT angiography. Choroidal nevi are relatively common intraocular tumors. The presence of subretinal and intraretinal fluids can indicate that a CNV has occurred as a complication, warranting prompt management. However, subretinal and intraretinal fluids are also documented in nevi w...
PURPOSE Age-related macular degeneration caused by choroidal neovascularization (CNV) remains difficult to be treated despite the recent advent of several treatment options. In this study, we investigated the in vivo angiogenic control by intravenous injection of polyion complex (PIC) micelle encapsulating plasmid DNA (pDNA) using a mice CNV model. METHODS The transfection efficiency of the P...
Accurate and efficient genome-wide detection of copy number variants (CNVs) is essential for understanding human genomic variation, genome-wide CNV association type studies, cytogenetics research and diagnostics, and independent validation of CNVs identified from sequencing based technologies. Numerous, array-based platforms for CNV detection exist utilizing array Comparative Genome Hybridizati...
We report a case of recurrent choroidal neovascularization (CNV) in an eye with chorioretinal coloboma. A 36-year-old woman presented complaining of decreased visual acuity (VA) in her left eye. Best corrected visual acuity (BCVA) was 20/200 and iris coloboma was observed. Funduscopy and fluorescein angiography (FA) showed CNV in the superior extrafoveal region with chorioretinal coloboma reach...
The contingent negative variation (CNV) is a long-latency electroencephalography (EEG) surface negative potential with cognitive and motor components, observed during response anticipation. CNV is an index of cortical arousal during orienting and attention, yet its functional neuroanatomical basis is poorly understood. We used functional magnetic resonance imaging (fMRI) with simultaneous EEG a...
Genome-wide copy-number-variation study identified a susceptibility gene, UGT2B17, for osteoporosis.
Osteoporosis, a highly heritable disease, is characterized mainly by low bone-mineral density (BMD), poor bone geometry, and/or osteoporotic fractures (OF). Copy-number variation (CNV) has been shown to be associated with complex human diseases. The contribution of CNV to osteoporosis has not been determined yet. We conducted case-control genome-wide CNV analyses, using the Affymetrix 500K Arra...
PURPOSE Vasostatin 48 (VS48) is a peptide of 48 amino acids derived from calreticulin. This study aimed to investigate the effects of topical application of VS48 eyedrops on experimental choroidal neovascularization (CNV). METHODS Recombinant VS48 was expressed and purified as a thioredoxin (TRX)-fused protein, TRX-VS48. The anti-angiogenic effects of TRX-VS48 were validated by migration and ...
PURPOSE To detect and quantify choroidal neovascularization (CNV) in patients with age-related macular degeneration (AMD) using optical coherence tomography (OCT) angiography. DESIGN Observational, cross-sectional study. PARTICIPANTS A total of 5 normal subjects and 5 subjects with neovascular AMD were included. METHODS A total of 5 eyes with neovascular AMD and 5 normal age-matched contr...
