A perspective on automated rapid eye movement sleep assessment

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Rapid eye movement sleep is associated with distinct changes in various biomedical signals that can be easily captured during sleep, lending themselves to automated sleep staging using machine learning systems. Here, we provide a perspective on the critical characteristics of biomedical signals associated with rapid eye movement sleep and how ...

Traction suture fixation technique using a capsular tension ring fragment for severe lens displacement during cataract surgery in dogs

open access: yesVeterinary Ophthalmology, Volume 28, Issue 2, Page 197-206, March 2025.
Abstract Objectives To describe the traction suture fixation technique for severely displaced lenses (≥180°) using a capsular tension ring (CTR) fragment during cataract surgery in dogs, and to retrospectively investigate its clinical outcomes. Animals Studied Eight dogs (nine eyes). Procedures The medical records of dogs with severe lens displacement (

Ca2+-induced Light Adaptation in Retinal ON-bipolar Cells.

open access: yesThe Keio Journal of Medicine, 1999
Retinal ON-bipolar cells possess a metabotropic glutamate receptor linked to the control of a cGMP cascade, which functions to generate high synaptic amplification of rod signals under dark-adapted conditions. We report that a major component of light adaptation of the rod visual system results from a reduction in gain in synaptic transmission from ...

Techniques for subretinal injections in animals

open access: yesVeterinary Ophthalmology, Volume 28, Issue 2, Page 506-518, March 2025.
Abstract Subretinal injections are not commonly performed during clinical treatment of animals but are frequently used in laboratory animal models to assess therapeutic efficacy and safety of gene and cell therapy products. Veterinary ophthalmologists are often employed to perform the injections in the laboratory animal setting, due to knowledge of ...

Amacrine cell inputs to OFF midget ganglion cells in macaque retina

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The goal of this study was to explain the findings from physiological studies that OFF midget ganglion cells had larger receptive field centers than expected from their dendritic field diameters. First, we confirmed that OFF mRGCs (OFF MGC) receive input from diffuse bipolar cells (DB) as well as OFF midget bipolar cells (FMB ...

Spleen Tyrosine Kinase (SYK) is Necessary for cGAS‐STING Signaling in Müller Glia and Visual Function Deficits in Diabetic Mice

open access: yesGlia, Volume 74, Issue 6, June 2026.
Hyperglycemic conditions increased mitochondrial membrane permeability and inflammatory signaling in Müller cells via cGAS‐STING activation. SYK was necessary for cGAS–STING activation and increased cytokine expression in Müller cells. Müller glia‐specific SYK deletion reduced glial activation and attenuated inflammatory cytokine expression in the ...

A Dynamic Change of Microglial States Occurs During the Transition From Photoreceptor Degeneration to Regeneration in Zebrafish pde6c Mutants

open access: yesGlia, Volume 74, Issue 6, June 2026.
Zebrafish pde6c mutants undergo photoreceptor degeneration from 5 dpf, but rods regenerate from 4 wpf. scRNA‐seq of retinal microglia reveals dynamic change of states between 5 dpf and 4 wpf. Two states emerge specifically during regeneration. ABSTRACT Microglia, brain‐resident immune cells, maintain brain homeostasis.

Efficacy of omega‐3 fatty acids as a functional food: a multifaceted approach to health reinforcement

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 8, Page 4521-4549, June 2026.
Abstract Omega‐3 fatty acids (omega‐3s) are polyunsaturated fatty acids linked with numerous health benefits. Omega‐3s exhibit multifaceted activities through various mechanisms. Eicosapentaenoic acid (EPA) alleviates oxidative stress by lowering reactive oxygen species and improving oxidative stress in brain tissues and acts against neurodegenerative ...

Vitreoretinal complications and surgical outcomes in patients with X‐linked retinoschisis

open access: yesActa Ophthalmologica, Volume 104, Issue 4, Page 410-422, June 2026.
Abstract Purpose X‐linked retinoschisis (XLRS) is an inherited vitreoretinal disorder characterized by macular retinoschisis. In a subgroup of patients, peripheral retinoschisis can occur, potentially leading to complications such as vitreous haemorrhage (VH) and retinal detachment (RD).

Genetic Loss of VGLUT1 Alters Histogenesis of Retinal Glutamatergic Cells and Reveals Dynamic Expression of VGLUT2 in Cones

open access: yesBrain Sciences
Background/Objectives: Glutamatergic neurotransmission is essential for the normal functioning of the retina. Photoreceptor to bipolar and bipolar to ganglion cell signaling is mediated by L-glutamate, which is stored in and released from vesicular ...
