Compendium of Clinical Variant Classification for 2,246 Unique ABCA4 Variants to Clarify Variant Pathogenicity in Stargardt Disease Using a Modified ACMG/AMP Framework

open access: yesHuman Mutation, Volume 2023, Issue 1, 2023., 2023
Biallelic variants in ABCA4 cause Stargardt disease (STGD1), the most frequent heritable macular disease. Determination of the pathogenicity of variants in ABCA4 proves to be difficult due to (1) the high number of benign and pathogenic variants in the gene; (2) the presence of many rare ABCA4 variants; (3) the presence of complex alleles for which ...

Aster la vista: Unraveling the biochemical basis of carotenoid homeostasis in the human retina

open access: yesBioEssays, Volume 44, Issue 11, November 2022., 2022
Carotenoid pigments play critical roles as colorants, light filters, and chromophores. A novel class of lipid transfer proteins, the Aster proteins (GRAM‐domain containing) were identified. We discuss how the differential expression of Aster proteins and beta‐carotene‐oxygenase 2 (BCO2) establish the unique carotenoid distribution patterns in the ...

Retinal organoids derived from rhesus macaque iPSCs undergo accelerated differentiation compared to human stem cells

open access: yesCell Proliferation, Volume 55, Issue 4, April 2022., 2022
Stage 3 rhesus retinal organoids are composed of mature cell types including cone and rod photoreceptors. Abstract Purpose To compare the timing and efficiency of the development of Macaca mulatta, a nonhuman primate (NHP), induced pluripotent stem cell (rhiPSC) derived retinal organoids to those derived from human embryonic stem cells (hESCs ...

[Retracted] The Optos 200Tx Scanning Laser Ophthalmoscope Application in Retinoblastoma Patients’ Follow‐Up

open access: yesBioMed Research International, Volume 2022, Issue 1, 2022., 2022
Background and Objective. Examination under general anesthesia is the conventional method of follow‐up examination for retinoblastoma (RB) patients. As most of the RB patients are infants or children, general anesthesia for examination often put the children at great risk and affect their growth and development.

Alterations of retinal thickness measured by optical coherence tomography correlate with neurophysiological measures in diabetic polyneuropathy

open access: yesJournal of Diabetes Investigation, Volume 12, Issue 8, Page 1430-1441, August 2021., 2021
(1) The thickness of the foveal and parafoveal inner nuclear layer/outer plexiform layer increased in patients with clinical diabetic polyneuropathy compared with patients without clinical diabetic polyneuropathy. (2) A decrease in the thickness of the parafoveal ganglion cell complex correlated with deterioration of nerve functions in the nerve ...

Segmentation of Laser Marks of Diabetic Retinopathy in the Fundus Photographs Using Lightweight U‐Net

open access: yesJournal of Diabetes Research, Volume 2021, Issue 1, 2021., 2021
Diabetic retinopathy (DR) is a prevalent vision‐threatening disease worldwide. Laser marks are the scars left after panretinal photocoagulation, a treatment to prevent patients with severe DR from losing vision. In this study, we develop a deep learning algorithm based on the lightweight U‐Net to segment laser marks from the color fundus photos, which ...

Cardiovascular Properties of the Androgen‐Induced PCOS Model in Rats: The Role of Oxidative Stress

open access: yesOxidative Medicine and Cellular Longevity, Volume 2021, Issue 1, 2021., 2021
Polycystic ovary syndrome (PCOS) is a multifaced reproductive endocrinopathy affecting 6‐20% of women of childbearing age. It was previously shown that women with PCOS have an increased risk of cardiovascular (CV) diseases. The aim of this study was to evaluate the cardiodynamic parameters of isolated rats’ hearts, blood pressure levels, and ...
