Impact of obesity with impaired glucose tolerance on retinal degeneration in a rat model of metabolic syndrome. [PDF]

open access: yes, 2017
PurposeMetabolic syndrome (MetS) is associated with several degenerative diseases, including retinal degeneration. Previously, we reported on progressive retinal degeneration in a spontaneous obese rat (WNIN/Ob) model.

Eye shape and retinal shape, and their relation to peripheral refraction [PDF]

open access: yes, 2012
Purpose: We provide an account of the relationships between eye shape, retinal shape and peripheral refraction. Recent findings: We discuss how eye and retinal shapes may be described as conicoids, and we describe an axis and section reference system for

Retinal location and structure in squid rhodopsin [PDF]

open access: yes, 2021
In order to understand retinal we calculated the dihedral angles around carbon axis IOC-12C, since two different carbon sequences 9C-10C-11C-12C and 10C-11C-12C-13C exist. We also calculated the distances between two specified carbon pairs. Those results

Formation and enterohepatic circulation of metabolites ofc retinol and retinoic acid in bile duct-cannulated rats

open access: yesJournal of Lipid Research, 1966
Four hours after intraportal injection of retinoic acid-14C into bile duct-cannulated rats, less than 10% of the radioactivity was recovered in the liver, intestine, and kidneys. Within 6 hr, 40% of the radioactivity had appeared in bile.

Laser Photocoagulation for Retinal Detachments and Retinal Tears in Cytomegalovirus Retinitis

open access: yesOphthalmology, 1997
Retinal detachment complicates the course of cytomegalovirus (CMV) retinitis in nearly 30% of human immunodeficiency virus-infected patients. The study goal was to evaluate laser photocoagulation in the treatment of CMV retinitis-related retinal detachments and retinal tears.Nonrandomized, observational cohort study.Sixty-three patients with CMV ...

Retinal Image Restoration and Vessel Segmentation using Modified Cycle-CBAM and CBAM-UNet [PDF]

open access: yesarXiv, 2022
Clinical screening with low-quality fundus images is challenging and significantly leads to misdiagnosis. This paper addresses the issue of improving the retinal image quality and vessel segmentation through retinal image restoration. More specifically, a cycle-consistent generative adversarial network (CycleGAN) with a convolution block attention ...

Loss of synchronized retinal phagocytosis and age-related blindness in mice lacking alphavbeta5 integrin. [PDF]

open access: yes, 2004
Daily phagocytosis by the retinal pigment epithelium (RPE) of spent photoreceptor outer segment fragments is critical for vision. In the retina, early morning circadian photoreceptor rod shedding precedes synchronized uptake of shed photoreceptor ...
