Retinal findings in membranoproliferative glomerulonephritis

American Journal of Ophthalmology Case Reports, 2017
Purpose: To assess the evolution of retinal findings in patients with membranoproliferative glomerulonephritis (MPGN) by funduscopy, intravenous fluorescein angiography and optical coherence tomography. Observations: Three women and one man were followed

Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

Environmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.

Bile acid metabolism and signaling in human and animal health: A One Health perspective

iMetaOmics, EarlyView.
Bile acids maintain host homeostasis through enterohepatic circulation, microbial transformation, and bile acid receptor signaling, thereby regulating glucose and lipid metabolism, intestinal barrier integrity, and immunity. These effects support human disease intervention and health‐oriented animal production, reducing drug dependence and residue ...

Low‐contrast visual acuity versus low‐luminance visual acuity in choroideremia

Clinical and Experimental Optometry, EarlyView., 2020
Clinical relevance Choroideremia is a progressive X‐linked inherited rod‐cone dystrophy. Patients present with nyctalopia and progressive visual field loss, but visual acuity remains well preserved early on. This study showed that low‐luminance visual acuity may be a useful clinical outcome measure during earlier disease stages.

Eye Darkening Under Dehydration Stress in the Neotropical Frog Boana punctata (Schneider, 1799)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
Dehydration induces a strong and partially reversible increase in iris pigmentation in the Neotropical frog Boana punctata. The tight relationship between iris darkening and hydration state identifies ocular pigmentation as a simple, non‐invasive physiological biomarker with broad potential for assessing hydric stress in amphibian populations ...

Beyond the Classics: The Synergy of AI and Genomics Reveals an Expanded Repertoire of Pigmentation Genes

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Classical approaches for coloration analysis are limited by human low‐resolution phenotyping and genetic analysis. Artificial intelligence allows us to find genes beyond the tip of the iceberg that explain color and pattern diversity in nature. ABSTRACT Pigmentation has long served as a powerful system for exploring gene–trait relationships, yet much ...

Norbixin Protects Retinal Pigmented Epithelium Cells and Photoreceptors against A2E-Mediated Phototoxicity In Vitro and In Vivo.

PLoS ONE, 2016
The accumulation of N-retinylidene-N-retinylethanolamine (A2E, a toxic by-product of the visual pigment cycle) in the retinal pigment epithelium (RPE) is a major cause of visual impairment in the elderly.

Clinical and genetic features of pediatric hereditary polyposis syndromes in Israel: A nationwide multicenter cohort

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Hereditary polyposis syndromes in children are rare, heterogeneous disorders associated with significant morbidity and long‐term risk of malignancy. Current data on their presentation, management, and outcomes in pediatric populations remain limited.
