Deployment of spatial attention without moving the eyes is boosted by oculomotor adaptation

open access: yesFrontiers in Human Neuroscience, 2015
Vertebrates developed sophisticated solutions to select environmental visual information, being capable of moving attention without moving the eyes. A large body of behavioural and neuroimaging studies indicate a tight coupling between eye movements and ...

Adapting to blur produced by ocular high-order aberrations

open access: yesJournal of Vision, 2011
The perceived focus of an image can be strongly biased by prior adaptation to a blurred or sharpened image. We examined whether these adaptation effects can occur for the natural patterns of retinal image blur produced by high-order aberrations (HOAs) in the optics of the eye.

Dapagliflozin prevents methylglyoxal‐induced retinal cell death in ARPE‐19 cells

open access: yesFEBS Open Bio, EarlyView.
Diabetic macular oedema is a diabetes complication of the eye, which may lead to permanent blindness. ARPE‐19 are human retinal cells used to study retinal diseases and potential therapeutics. Methylglyoxal is a compound increased in uncontrolled diabetes due to elevated blood glucose.

Symptomatic recovery in Miller Fisher Syndrome parallels vestibular-perceptual and not vestibular-ocular reflex function

open access: yesFrontiers in Neurology, 2011
Unpleasant visual symptoms including oscillopsia and dizziness may occur when there is unexpected motion of the visual world across the subject’s retina (‘retinal-slip’) as in an acute spontaneous nystagmus or on head movement with an acute ...

Randomized trial of polychromatic blue-enriched light for circadian phase shifting, melatonin suppression, and alerting responses. [PDF]

open access: yes, 2019
Wavelength comparisons have indicated that circadian phase-shifting and enhancement of subjective and EEG-correlates of alertness have a higher sensitivity to short wavelength visible light.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Ocular Clocks: Adapting Mechanisms for Eye Functions and Health

open access: yesInvestigative Opthalmology & Visual Science, 2018
Vision is a highly rhythmic function adapted to the extensive changes in light intensity occurring over the 24-hour day. This adaptation relies on rhythms in cellular and molecular processes, which are orchestrated by a network of circadian clocks located within the retina and in the eye, synchronized to the day/night cycle and which, together, fine ...

Antimalarials and the eye [PDF]

open access: yes, 1989
Following the first reports in 1954 of the beneficial effects of chloroquine in cases of lupus erythematosus, this drug and its numerous derivatives have been used extensively in the treatment of systemic and discoid lupus erythematosus and rheumatoid ...

Glaucomatous vertical vessel density asymmetry of the temporal raphe detected with optical coherence tomography angiography. [PDF]

open access: yes, 2020
Changes in retinal vasculature and ocular circulation may play an important role in the glaucoma development and progression. We evaluated the vertical asymmetry across the temporal raphe of the deep retinal layer vessel density, using swept-source ...

Applicability of mitotic figure counting by deep learning: a development and pan‐cancer validation study

open access: yesFEBS Open Bio, EarlyView.
In this study, we developed a deep learning method for mitotic figure counting in H&E‐stained whole‐slide images and evaluated its prognostic impact in 13 external validation cohorts from seven different cancer types. Patients with more mitotic figures per mm2 had significantly worse patient outcome in all the studied cancer types except colorectal ...
