Optic Nerve Head Parameters, Retinal Nerve Fiber Layer and Executive Functions in Children with Attention Deficit Hyperactivity Disorder [PDF]

open access: yes
Aim: This study aimed to evaluate the relationship between executive functions and optic nerve head parameters (the disc area, the neuroretinal rim volume and cup-to-disc ratio) and peripapillary retinal nerve fiber layer (pRNFL) in medication-free ...

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

open access: yesFEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Anatomy and evaluation of the optic nerve head

open access: yesArquivos Brasileiros de Oftalmologia, 2021
Evaluation of the optic disc is important for the correct diagnosis and follow-up of optic neuropathies, especially glaucoma. The characteristics of the optic disc depend on various factors, including demographic and population aspects, and analysis of these characteristics may vary according to the methods used.

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora

open access: yesFEBS Open Bio, EarlyView.
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

Differential Activation of Glioprotective Intracellular Signaling Pathways in Primary Optic Nerve Head Astrocytes after Treatment with Different Classes of Antioxidants

open access: yesAntioxidants, 2020
Optic nerve head astrocytes are the specialized glia cells that provide structural and trophic support to the optic nerve head. In response to cellular injury, optic nerve head astrocytes undergo reactive astrocytosis, the process of cellular activation ...

Optic nerve hypoplasia in the fetal alcohol syndrome:a mouse model [PDF]

open access: yes, 1995
Optic nerve hypoplasia is commonly observed in children affected by the fetal alcohol syndrome, and is believed to contribute to their poor visual acuity.

Approach to the Diagnosis and Differentiation of Glaucomatous and Nonglaucomatous Optic Neuropathies

open access: yes, 2014
Optic neuropathy denotes degeneration of the retinal ganglion cells with functional and structural impairment of the optic nerve. Functional damage of the optic nerve can be evaluated by checking visual acuity, color vision, pupillary function, and ...

White Matter Hyperintensity Burden and Short‐Interval Change Associated With Sleep Apnoea in the UK Biobank

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Purpose White matter hyperintensities (WMH) are a core neuroimaging marker of cerebral small vessel disease (CSVD). Sleep apnoea (SA) is a recognized vascular risk factor, but its associations with regional WMH burden, short‐interval WMH change and cognitive performance in population‐based cohorts remain incompletely defined. We

Macular Retinal Ganglion Cell Complex Thickness and Its Relationship to the Optic Nerve Head Topography in Glaucomatous Eyes with Hemifield Defects

open access: yesJournal of Ophthalmology, 2011
Purpose. To evaluate the relationship between the macular ganglion cell complex (mGCC) thickness, which is the sum of the retinal nerve fiber, ganglion cell, and inner plexiform layers, measured with a spectral-domain optical coherence tomograph and the ...
