Retinal oximetry [PDF]

open access: yesActa Ophthalmologica, 2013
Abstract.Purpose:Malfunction of retinal blood flow or oxygenation is believed to be involved in various diseases. Among them are retinal vessel occlusions, diabetic retinopathy and glaucoma. Reliable, non‐invasive technology for retinal oxygen measurements has been scarce and most of the knowledge on retinal oxygenation comes from animal studies.

Impaired endothelial function of the retinal vasculature in hypertensive patients [PDF]

open access: yes, 2004
<p><b>Background and Purpose:</b> Arterial hypertension constitutes a central factor in the pathogenesis of stroke. We examined endothelial function of the retinal vasculature as a model of the cerebral circulation.</p> <p ...

Retinal prostheses in degenerative retinal diseases

open access: yesJournal of the Chinese Medical Association, 2015
Degenerative retinal diseases may lead to significant loss of vision. Age-related macular degeneration (AMD) and retinitis pigmentosa (RP), which eventually affect the photoreceptors, are the two most common retinal degenerative diseases. Once the photoreceptorcells are lost, there are no known effective therapies for AMD or RP.

Occlusion of retinal capillaries caused by glial cell proliferation in chronic ocular inflammation [PDF]

open access: yes, 2015
The inner blood-retinal barrier is a gliovascular unit in which glial cells surround capillary endothelial cells and regulate retinal capillaries by paracrine interactions.

Monitoring retinal changes with optical coherence tomography predicts neuronal loss in experimental autoimmune encephalomyelitis. [PDF]

open access: yes, 2019
BACKGROUND:Retinal optical coherence tomography (OCT) is a clinical and research tool in multiple sclerosis, where it has shown significant retinal nerve fiber (RNFL) and ganglion cell (RGC) layer thinning, while postmortem studies have reported RGC loss.

Photoreceptor Outer Segment-like Structures in Long-Term 3D Retinas from Human Pluripotent Stem Cells. [PDF]

open access: yes, 2017
The retinal degenerative diseases, which together constitute a leading cause of hereditary blindness worldwide, are largely untreatable. Development of reliable methods to culture complex retinal tissues from human pluripotent stem cells (hPSCs) could ...

The effects of growth factors on multicellular spheroids formed by chick embryonic retinal cells [PDF]

open access: yes, 1997
Retinal cells from chick embryos aged 7.5 days of gestation were cultured for two months in a non-adherent suspension culture dish to study the effects of growth factors and co-culture with retinal pigment epithelial cells on their differentiation ...

A Smartphone-Based Tool for Rapid, Portable, and Automated Wide-Field Retinal Imaging. [PDF]

open access: yes, 2018
Purpose:High-quality, wide-field retinal imaging is a valuable method for screening preventable, vision-threatening diseases of the retina. Smartphone-based retinal cameras hold promise for increasing access to retinal imaging, but variable image quality

Stochastic variation in the FOXM1 transcription program mediates replication stress tolerance

open access: yesMolecular Oncology, EarlyView.
Cellular heterogeneity is a major cause of drug resistance in cancer. Segeren et al. used single‐cell transcriptomics to investigate gene expression events that correlate with sensitivity to the DNA‐damaging drugs gemcitabine and prexasertib. They show that dampened expression of transcription factor FOXM1 and its target genes protected cells against ...
