SS-OCTA assessment of fundus microvascular changes and their correlation with coronary lesion severity in severe coronary heart disease.

This study aimed to quantify fundus microvascular alterations in patients requiring revascularization for coronary heart disease (CHD) using swept-source optical coherence tomography angiography (SS-OCTA) and to investigate the correlation between these alterations and the severity of coronary artery lesions. SS-OCTA was employed to assess the fundus neurovascular parameters of all participants, while the Gensini score was utilized to gauge the severity of coronary artery lesions in observation group. A total of 98 participants (49 CHD patients and 49 controls) were included.

Caspase-1 Inhibition Ameliorates Photoreceptor Damage Following Retinal Detachment by Inhibiting Microglial Pyroptosis.

Retinal detachment (RD) is a sight-threatening condition that occurs in several retinal diseases. Microglia that reside in retina are activated after RD and play a role in the death of photoreceptor cells. The involvement of microglial pyroptosis in the early pathological process of RD is still unclear.

Metagenomic Next-Generation Sequencing to Investigate Infectious Endophthalmitis of Brucella: A Case Report.

Introduction: Brucellosis is a systemic disease that exists prevalently in clinical manifestations. The symptoms present in organs such as the eyes (in ocular brucellosis) can lead to misdiagnosis or even failure to diagnose. Metagenomic Next-Generation Sequencing (mNGS), a high-throughput sequencing approach, could be applied for the detection of microorganisms.

CD24 blunts the sensitivity of retinoblastoma to vincristine by modulating autophagy.

Retinoblastoma (RB) is the most common childhood malignant intraocular tumor. The clinical efficacy of vincristine (VCR) in the treatment of RB is severely limited by drug resistance. Here, we found that CD24, a GPI-anchored protein, was overexpressed in human RB tissues and RB cell lines, and was associated with the sensitivity of RB cells in response to VCR therapy.

Biomarkers in retinoblastoma.

Retinoblastoma (RB) is the most common intraocular malignancy of childhood caused by inactivation of the genes. The prognosis of RB is better with an earlier diagnosis. Many diagnostic approaches and appropriate clinical treatments have been developed to improve clinical outcomes.

Single-Cell RNA Sequencing of hESC-Derived 3D Retinal Organoids Reveals Novel Genes Regulating RPC Commitment in Early Human Retinogenesis.

The development of the mammalian retina is a complicated process involving the generation of distinct types of neurons from retinal progenitor cells (RPCs) in a spatiotemporal-specific manner. The progression of RPCs during retinogenesis includes RPC proliferation, cell-fate commitment, and specific neuronal differentiation. In this study, by performing single-cell RNA sequencing of cells isolated from human embryonic stem cell (hESC)-derived 3D retinal organoids, we successfully deconstructed the temporal progression of RPCs during early human retinogenesis.

The rescue effect of mesenchymal stem cell on sodium iodate-induced retinal pigment epithelial cell death through deactivation of NF-κB-mediated NLRP3 inflammasome.

Age-related macular degeneration (AMD) is a multifactorial disease resulting in the gradual loss of retinal pigment epithelium (RPE) and the permanent visual damage. Various risk factors, including oxidative stress, form a complex network at the confluence of inflammation. Mesenchymal stem cell (MSC) is a well-studied population of adult stem cell with strong neuroprotective and immunoregulatory properties.
