Concurrent macular neovascularization in shallow irregular retinal pigment epithelium elevation phenotypes in age‐related macular degeneration and chronic central serous chorioretinopathy: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract This systematic review and meta‐analysis synthesized the reported frequency of concurrent macular neovascularization (MNV) among selected eyes with author‐defined shallow irregular retinal pigment epithelium (RPE) elevations in age‐related macular degeneration (AMD) and chronic central serous chorioretinopathy (CSC).

Regional growth kinetics of geographic atrophy in age‐related macular degeneration with and without fovea‐sparing

Acta Ophthalmologica, EarlyView.
Abstract Purpose Fovea‐sparing geographic atrophy (GA) patients retain near‐normal central vision. To better understand GA progression in relation to the fovea, we performed a semi‐automated image analysis of regional atrophy growth in a long‐term GA natural‐history cohort. Methods Prospective‐observational, single‐centre‐study (02/2013–07/2025) at the

A Bias-free Deep Learning Approach for Automated Sunspot Segmentation

The Astrophysical Journal
Solar activities significantly influence space weather and the Earth’s environment, necessitating accurate and efficient sunspot detection. This study explores deep learning methods to automate sunspot identification in solar satellite images, keeping ...

Optic nerve head blood flow autoregulation during isometric exercise in primary open‐angle glaucoma assessed by laser speckle flowgraphy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To assess optic nerve head blood flow (ONHBF) autoregulation in patients with early‐ to moderate‐stage primary open‐angle glaucoma (POAG) and age‐ and sex‐matched healthy controls using laser speckle flowgraphy (LSFG) and isometric handgrip exercise.

A novel myopathy with autophagic vacuoles associated with biallelic variants in CLN8

Brain Pathology, EarlyView.
We describe a novel adult‐onset myopathy with autophagic vacuoles and characteristic features of ceroid lipofuscinosis associated with biallelic CLN8 variants, seizures, and muscle weakness. Autophagosomal/lysosomal deposition of curvilinear, autofluorescent material containing the mitochondrial adenosine triphosphate (ATP) synthase membrane subunit c ...

Superstrong Magnetic Fields in Sunspot Bipolar Light Bridges

The Astrophysical Journal Letters
Recent solar observations of bipolar light bridges (BLBs) in sunspots have, in a few individual cases, revealed magnetic fields up to 8.2 kG, which is at least twice as strong as typical values measured in sunspot umbrae.

Renal‐vascular axis: unmasking its role in vascular endothelial growth factor‐inhibitor vascular toxicity in cancer patients

British Journal of Pharmacology, EarlyView.
Abstract Vascular toxicity is a growing concern in cancer patients receiving vascular endothelial growth factor inhibitor (VEGFi) therapy, posing a significant threat to patient prognosis. While the primary mechanism of VEGFi‐induced vascular toxicity is linked to redox‐sensitive reactions that disrupt vascular tone, leading to hypertension and ...

Differential Rotation of Individual Sunspots and Pores

The Astrophysical Journal
The analysis of the rotation rate of individual sunspots and pores was performed according to the data from the processing of observations by the Solar Dynamics Observatory/Helioseismic and Magnetic Imager in the period 2010–2024.

CRB1‐Associated Inherited Retinal Dystrophies: Prospective Natural History Study With 4 Years of Follow‐Up

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background The lack of validated and sensitive clinical endpoints remains a major challenge in the design of gene therapy trials for inherited retinal dystrophies (IRDs). This prospective longitudinal cohort study describes the natural disease progression of IRDs caused by pathogenic mutations in the Crumbs homologue 1 (CRB1) gene, and ...

Can a Major Geomagnetic and Auroral Disturbance Originate From a Solar Active Region Close to the Limb?

Space Weather
When forecasting major geomagnetic storms, it is commonly assumed that coronal eruptions near the solar limb are not of concern. We here discuss two sequences of events: the Fátima storms of January 1938 and the Halloween storms of October/November 2003.
