We have recently reported spinal blood flow-metabolism uncoupling in an amyotrophic lateral sclerosis (ALS) animal model using Cu/Zn-superoxide dismutase 1 (SOD1)-transgenic (Tg) mice, suggesting a relative hypoxia in the spinal cord. However, the hypoxic stress sensor pathway has not been well studied in ALS. Here, we examined temporal and spatial changes(More)
Interphotoreceptor retinoid-binding protein (IRBP) secreted by photoreceptors plays a pivotal role in photoreceptor survival with an unknown mechanism. A mutation in the human IRBP has been linked to retinitis pigmentosa, a progressive retinal degenerative disease. Mice lacking IRBP display severe early and progressive photoreceptor degeneration. However,(More)
PURPOSE To describe the clinical and genetic characteristics of a Japanese family in which one member exhibited Bietti's crystalline corneoretinal dystrophy (BCD). METHODS Using direct sequencing, mutation screening was performed in the CYP4V2 gene of both the patient with BCD and her daughter. Ophthalmic examinations were performed to determine the(More)
PURPOSE The 65 kDa retinal pigment epithelium-specific protein, RPE65, is an essential enzyme for 11-cis-retinal synthesis in the eye. Mutations of the RPE65 gene in humans result in severe vision loss, and Rpe65(-/-) mice show early cone photoreceptor degeneration. We used an explant culture system to evaluate whether posttranslational downregulation of(More)
Apolipoprotein E (ApoE) plays important roles in the body, including a carrier of cholesterols, an anti-oxidant, and a ligand for the low-density lipoprotein receptors. In the nervous system, the presence of ApoE4 isoforms is associated with Alzheimer's disease. ApoE gene polymorphisms are also associated with glaucoma, but the function of ApoE in the(More)
We herein report the case of a 60-year-old man showing overexpression of creatine kinase (hyperCKemia) related to initial and recurrent attacks of neuromyelitis optica (NMO). He showed reduced vision, ataxia and dysesthesia, but no symptoms originating in the muscles. Magnetic resonance imaging (MRI) revealed lesions in the optic nerve, medulla oblongata,(More)
Recently, topical dexamethasone-induced ocular hypertension and a consequent loss of retinal ganglion cells (RGCs) have been described in mice. This has been proposed as a model of steroid-induced glaucoma. In this study, we set up and evaluated a similar model in rats. Ten-week old Sprague Dawley (SD) rats (N = 12) were used to evaluate the effect of(More)
Parkinson's disease with dementia (PDD) and dementia with Lewy bodies (DLB) both commonly exhibit brain Lewy body pathology and similar end-stage symptoms, but early symptoms differ. To clarify these differences, we compared the demographic characteristics, symptoms, cognitive and affective functioning, activities of daily life, and neuroimaging results(More)
The objective of this study is to determine whether diffusion tensor imaging (DTI) tractography analysis is a potential method for differentiating cerebellar ataxia patients with multiple system atrophy with predominant cerebellar ataxia (MSA-C) and cortical cerebellar atrophy (CCA). Forty-one MSA-C patients (62.7 ± 8.1 years old, mean ± SD) and age- and(More)
Clinical data from Japan on the safety and real-world outcomes of alteplase (tPA) thrombolysis in the extended therapeutic window are lacking. The aim of this study was to assess the safety and real-world outcomes of tPA administered within 3–4.5 h of stroke onset. The study comprised consecutive acute ischemic stroke patients (n = 177) admitted across five(More)
