Brain derived neurotrophic factor keeps pattern electroretinogram from dropping after superior colliculus lesion in mice [PDF]

International Journal of Ophthalmology, 2016
AIM: To determine if brain-derived neurotrophic factor (BDNF) could offer protention to retinal ganglion cells following a superior colliculus (SC) lesion in mice using pattern electroretinogram (PERG) and optical coherence tomography (OCT) as a measures

Effect of Active and Passive Smoking on Retinal Nerve Fibre Layer and Ganglion Cell Complex

Journal of Ophthalmology, 2017
Aim. To evaluate the possible structural and functional changes in the retinal nerve fibre layer (RNFL) and the ganglion cell complex (GCC) of chronic smokers and compare them with those of passive healthy smokers using spectral domain optical coherence ...

Pattern electroretinography (PERG).

, 2014
The larger graphs represent averaged (bolded) and invididual PERG traces (thin dashed lines) for R6/2 (blue) and wild-type (red) mice. The ratio analysis (insert) derived from PERG amplitude/photopic b-wave amplitude shows no difference between the ...

Early Retinal UCHL1 Dysregulation Coupled With Synaptic Loss Reflects Alzheimer's Disease Severity

Advanced Science, EarlyView.
This study identifies synapse‐enriched deubiquitinase UCHL1 as an early Aβ‐responsive regulator of retinal synaptopathy in Alzheimer's disease. Retinal UCHL1 loss accompanies excitatory synapse degeneration, p75NTR activation, and neuroinflammation, and predicts Braak stage and cognitive decline. Aβ42 fibrils trigger synaptic and UCHL1 depletion before

Insect communities of late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada

Journal of Quaternary Science, EarlyView.
ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...
