An aptamer-tethered DNA origami amplifier for sensitive and accurate imaging of intracellular microRNA

Nanoscale. 2022 Jan 27;14(4):1327-1332. doi: 10.1039/d1nr06399e. ABSTRACT Accurate detection and imaging of low-abundance microRNA (miRNA) in living cells are essential for the diagnosis and prognosis of diseases. Designing nanoprobes with resistance to enzyme degradation, effective cell-binding, and efficient signal amplification is crucial for in vivo imaging. In this study, we present an aptamer-tethered DNA origami […]

Mitochondrial Retinopathies

Int J Mol Sci. 2021 Dec 25;23(1):210. doi: 10.3390/ijms23010210. ABSTRACT The retina is an exquisite target for defects of oxidative phosphorylation (OXPHOS) associated with mitochondrial impairment. Retinal involvement occurs in two ways, retinal dystrophy (retinitis pigmentosa) and subacute or chronic optic atrophy, which are the most common clinical entities. Both can present as isolated or […]

Omega-3 fatty acids promote neuroprotection, decreased apoptosis and reduced glial cell activation in the retina of a mouse model of OPA1-related autosomal dominant optic atrophy

Exp Eye Res. 2022 Feb;215:108901. doi: 10.1016/j.exer.2021.108901. Epub 2021 Dec 20. ABSTRACT The purpose of this study was to evaluate the neuroprotective effects of omega-3 polyunsaturated fatty acid (ω3-PUFA) supplementation in a mouse model of OPA1-associated autosomal dominant optic atrophy (ADOA). The blood level of arachidonic acid (AA) and eicosapentaenoic acid (EPA) served to adjust […]

Autosomal dominant optic atrophy: A novel treatment for OPA1 splice defects using U1 snRNA adaption

Mol Ther Nucleic Acids. 2021 Oct 21;26:1186-1197. doi: 10.1016/j.omtn.2021.10.019. eCollection 2021 Dec 3. ABSTRACT Autosomal dominant optic atrophy (ADOA) is frequently caused by mutations in the optic atrophy 1 (OPA1) gene, with haploinsufficiency being the major genetic pathomechanism. Almost 30% of the OPA1-associated cases suffer from splice defects. We identified a novel OPA1 mutation, c.1065+5G>A, […]

Induced Pluripotent Stem Cells for Inherited Optic Neuropathies-Disease Modeling and Therapeutic Development

J Neuroophthalmol. 2022 Mar 1;42(1):35-44. doi: 10.1097/WNO.0000000000001375. Epub 2021 Sep 30. ABSTRACT BACKGROUND: Inherited optic neuropathies (IONs) cause progressive irreversible visual loss in children and young adults. There are limited disease-modifying treatments, and most patients progress to become severely visually impaired, fulfilling the legal criteria for blind registration. The seminal discovery of the technique for […]

Red Light Irradiation In Vivo Upregulates DJ-1 in the Retinal Ganglion Cell Layer and Protects against Axotomy-Related Dendritic Pruning

Int J Mol Sci. 2021 Aug 4;22(16):8380. doi: 10.3390/ijms22168380. ABSTRACT Retinal ganglion cells (RGCs) undergo dendritic pruning in a variety of neurodegenerative diseases, including glaucoma and autosomal dominant optic atrophy (ADOA). Axotomising RGCs by severing the optic nerve generates an acute model of RGC dendropathy, which can be utilized to assess the therapeutic potential of […]

The effect of serifs and stroke contrast on low vision reading

Acta Psychol (Amst). 2023 Feb;232:103810. doi: 10.1016/j.actpsy.2022.103810. Epub 2022 Dec 21. ABSTRACT PURPOSE: Patients with low vision are generally recommended to use the same fonts as individuals with normal vision. However, we are yet to fully understand whether stroke width and serifs (small ornamentations at stroke endings) can increase readability. This study’s purpose was to […]

Expectation-Maximization-Based Simultaneous Localization and Mapping for Millimeter-Wave Communication Systems

Sensors (Basel). 2022 Sep 14;22(18):6941. doi: 10.3390/s22186941. ABSTRACT In this paper, we proposed a novel expectation-maximization-based simultaneous localization and mapping (SLAM) algorithm for millimeter-wave (mmW) communication systems. By fully exploiting the geometric relationship among the access point (AP) positions, the angle difference of arrival (ADOA) from the APs and the mobile terminal (MT) position, and […]

Autosomal dominant optic atrophy caused by six novel pathogenic OPA1 variants and genotype-phenotype correlation analysis

BMC Ophthalmol. 2022 Jul 26;22(1):322. doi: 10.1186/s12886-022-02546-0. ABSTRACT PURPOSE: To describe the genetic and clinical features of nineteen patients from eleven unrelated Chinese pedigrees with OPA1-related autosomal dominant optic atrophy (ADOA) and define the phenotype-genotype correlations. METHODS: Detailed ophthalmic examinations were performed. Targeted next-generation sequencing (NGS) was conducted in the eleven probands using a custom […]
