Comparative mechanistic study of RPE cell death induced by different oxidative stresses

open access: yesRedox Biology, 2023
Oxidative stress is hypothesized to drive the progression of age-related macular degeneration (AMD). Retinal pigment epithelial (RPE) cell layer is important for supporting the function of retina and is particularly susceptible to oxidative stress ...

Comparison of RPE (Rating of Perceived Exertion) Scales for Session RPE

open access: yesInternational Journal of Sports Physiology and Performance, 2019
Purpose: The session rating of perceived exertion (sRPE) is a well-accepted method of monitoring training load in athletes in many different sports. It is based on the category-ratio (0–10) RPE scale (BORG-CR10) developed by Borg. There is no evidence how substitution of the Borg 6–20 RPE scale (BORG-RPE) might influence the sRPE in athletes.

Exosomal MiRNA Transfer between Retinal Microglia and RPE

open access: yesInternational Journal of Molecular Sciences, 2020
The retinal pigment epithelium (RPE), the outermost layer of the retina, provides essential support to both the neural retina and choroid. Additionally, the RPE is highly active in modulating functions of immune cells such as microglia, which migrate to ...

RPE necroptosis in response to oxidative stress and in AMD

open access: yesAgeing Research Reviews, 2015
Age-related macular degeneration (AMD) is the leading cause of irreversible blindness in the elderly. The underlying mechanism of non-neovascular AMD (dry AMD), also named geographic atrophy (GA) remains unclear and the mechanism of retinal pigment ...

Increased LCN2 (lipocalin 2) in the RPE decreases autophagy and activates inflammasome-ferroptosis processes in a mouse model of dry AMD

open access: yesAutophagy, 2022
In dry age-related macular degeneration (AMD), LCN2 (lipocalin 2) is upregulated. Whereas LCN2 has been implicated in AMD pathogenesis, the mechanism remains unknown.

Hypoxia aggravates ferroptosis in RPE cells by promoting the Fenton reaction

open access: yesCell Death and Disease, 2022
Oxidative stress and hypoxia in the retinal pigment epithelium (RPE) have long been considered major risk factors in the pathophysiology of age-related macular degeneration (AMD), but systematic investigation of the interplay between these two risk ...

Peculiarities of the Norton conversions application when matching impedances with different transformation coefficients

open access: yesФизика волновых процессов и радиотехнические системы, 2022
The paper studies the features and consequences of the use of Norton conversions in the process of broadband and narrowband matching of circuit impedances based on filter theory in cases with different transformation ratios.

Phase frequency characteristics evaluation for E-class devices output circuits

open access: yesФизика волновых процессов и радиотехнические системы, 2022
Based on the unitarity of the E-class device circuit [S]-matrix, the phase frequency characteristics are estimated for the output circuit at any harmonic of the fundamental frequency.

Skeletal and alveolar changes in conventional rapid palatal expansion (RPE) and miniscrew-assisted RPE (MARPE): a prospective randomized clinical trial using low-dose CBCT

open access: yesBMC Oral Health, 2022
Background This prospective randomized clinical trial aimed to evaluate the immediate and short-term skeletal, dentoalveolar, and periodontal effects of rapid palatal expansion (RPE) and miniscrew-assisted RPE (MARPE) in adolescent and young adult ...
