3D ophthalmic ultrasonography at the slit lamp using existing ultrasound systems.

PLoS One

January 2025

Department of Ophthalmology, Gavin Herbert Eye Institute, University of California Irvine, Irvine, California, United States of America.

Purpose: This study aims to explore the feasibility and performance of three-dimensional ultrasound (3DUS) imaging in ophthalmology using commercially available ultrasound probes adapted to a slit lamp.

Significance: Despite ultrasound's long-standing application in eye care for visualizing ocular components, the evolution of 3DUS technology has remained inactive, with limited development and commercial availability. This study introduces a novel method that could potentially enhance ophthalmic diagnostics and treatment planning by providing comprehensive 3D views of ocular structures using existing ultrasound probes adapted to the conventional slit lamp.

Retinopathy with Vitamin E Deficiency (RVED) is a familial disease in the English Cocker Spaniel (ECS) dog breed. Ophthalmic abnormalities observed in RVED-affected ECS include lipofuscin granule deposition within the tapetal fundus and subsequent retinal degeneration resulting in visual deficits. Affected dogs may also exhibit neurological signs that include ataxia and hindlimb proprioceptive deficit.

Integrin Trafficking, Fibronectin Architecture, and Glomerular Injury upon AdipoR1 Depletion.

J Am Soc Nephrol

January 2025

Research Program for Clinical and Molecular Metabolism, Faculty of Medicine, University of Helsinki, Helsinki, Finland.

Background: Deficiency of adiponectin and its downstream signaling may contribute to the pathogenesis of kidney injury in type 2 diabetes. Adiponectin activates intracellular signaling via adiponectin receptors 1 and 2 (AdipoR1 and AdipoR2), but the role of AdipoR-mediated signaling in glomerular injury in type 2 diabetes remains unknown.

Methods: The expression of AdipoR1 in the kidneys of people with type 2 diabetes and the expression of podocyte proteins or injury markers in the kidneys of AdipoR1-knockout (AdipoR1-KO) mice and immortalized AdipoR1-deficient human podocytes were investigated by immunohistochemistry and immunoblotting.

A nationwide survey in the USA reported that healthcare workers had the highest prevalence of short sleep duration compared with other professions. Moreover, several studies have reported poor sleep quality among healthcare professionals and described insufficient sleep as a potential driver of reduced physician well-being. This study aims to explore sleep quality and mental health issues among Syrian medical residents, with the goal of informing targeted interventions to enhance their well-being and professional performance.

The neuronal ceroid lipofuscinoses (NCLs) are a group of recessively inherited neurodegenerative diseases characterizsed by lysosomal storage of fluorescent materials. CLN3 disease, or juvenile Batten disease, is the most common NCL that is caused by mutations in the Ceroid Lipofuscinosis, Neuronal 3 (CLN3) gene. Sleep disturbances are among the most common symptoms associated with CLN3 disease that deteriorate the patients' life quality, yet this is understudied and has not been delineated in animal models of the disease.

Glia Modulates Immune Responses in the Retina Through Distinct MHC Pathways.

Glia

January 2025

Department of Ophthalmology, Bern University Hospital and Department of BioMedical Research, University of Bern, Bern, Switzerland.

Glia antigen-presenting cells (APCs) are pivotal regulators of immune surveillance within the retina, maintaining tissue homeostasis and promptly responding to insults. However, the intricate mechanisms underlying their local coordination and activation remain unclear. Our study integrates an animal model of retinal injury, retrospective analysis of human retinas, and in vitro experiments to gain insights into the crucial role of antigen presentation in neuroimmunology during retinal degeneration (RD), uncovering the involvement of various glial cells, notably Müller glia and microglia.

Purpose: The Teller Acuity Card (TAC) procedure is a preferential-looking method to assess visual acuity in infants and preverbal children and provides a quantitative measure of grating acuity. Several studies containing reference values have been published, the majority based on an older version of the TAC card set. In 2003, a new version of the TAC was released, called the TAC II.

Research on the function of epigenetic regulation in the inflammation of non-alcoholic fatty liver disease.

Life Med

August 2024

Department of Hepatobiliary Surgery, Xi-Jing Hospital, Fourth Military Medical University, Changle West Road, Xincheng District, Xi'an, Shaanxi 710032, China.

Nonalcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver condition, characterized by a spectrum that progresses from simple hepatic steatosis to nonalcoholic steatohepatitis, which may eventually lead to cirrhosis and hepatocellular carcinoma. The precise pathogenic mechanisms underlying NAFLD and its related metabolic disturbances remain elusive. Epigenetic modifications, which entail stable transcriptional changes without altering the DNA sequence, are increasingly recognized as pivotal.

Deciphering the dynamic single-cell transcriptional landscape in the ocular surface ectoderm differentiation system.

Life Med

October 2024

State Key Laboratory of Ophthalmology, Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangdong Provincial Key Laboratory of Ophthalmology Visual Science, Guangzhou 510060, China.

The ocular surface ectoderm (OSE) is essential for the development of the ocular surface, yet the molecular mechanisms driving its differentiation are not fully understood. In this study, we used single-cell transcriptomic analysis to explore the dynamic cellular trajectories and regulatory networks during the differentiation of embryonic stem cells (ESCs) into the OSE lineage. We identified nine distinct cell subpopulations undergoing differentiation along three main developmental branches: neural crest, neuroectodermal, and surface ectodermal lineages.
