Pediatric eye movement-based perimetry: progress, pitfalls, and prospects

open access: yesFrontiers in Ophthalmology
IntroductionEye movement-based perimetry (EMP) is a promising, non-invasive approach for visual field assessment, particularly in pediatric populations where standard automated perimetry often fails.

A matter of time: Improvement of visual temporal processing during training-induced restoration of light detection performance

open access: yesFrontiers in Psychology, 2015
The issue of how basic sensory and temporal processing are related is still unresolved. We studied temporal processing, as assessed by simple visual reaction times (RT) and double-pulse resolution (DPR), in patients with partial vision loss after visual ...

Detection and correlation of changes on perimetry and optical coherence tomography in patients on chronic usage of hydroxychloroquine: A Cross-Sectional StudyDetection and Correlation of changes on Perimetry and Optical coherence tomography in patients on Chronic Usage of Hydroxychloroquine: A cross-sectional study

open access: yesIndian Journal of Rheumatology, 2022
Background: Early detection of retinal toxicity in patients on chronic usage of hydroxychloroquine (HCQ) and thereby the prevention of irreversible visual loss is an important goal. Methods: We performed a comprehensive ophthalmologic examination, visual

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Unexplained Progressive Visual Field Loss in the Presence of Normal Retinotopic Maps

open access: yesFrontiers in Psychology, 2018
Lesions of primary visual cortex or its primary inputs typically result in retinotopically localized scotomas. Here we present an individual with unexplained visual field loss and deficits in visual perception in the absence of structural damage to the ...

Orientation of \u3ci\u3eHylobius Pales\u3c/i\u3e and \u3ci\u3ePachylobius Picivorus\u3c/i\u3e (Coleoptera: Curculionidae) to Visual Cues [PDF]

open access: yes, 2017
Pitfall traps with above-ground silhouettes of various colors and diameters were used in field tests to evaluate the role of vision in host orientation by adult pales weevils, Hylobius pales, and pitch-eating weevils, Pachylobius picivorus.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

To compare central visual field progression using mean deviation and pointwise linear regression analysis

open access: yesIndian Journal of Ophthalmology, 2023
Purpose: To compare central visual field progression using mean deviation and pointwise linear regression (PLR) analysis. Methods: We analyzed the 10-2 Humphrey visual field (HVF) tests for moderate and advanced primary glaucoma who had undergone at ...
