Modeling of external self-excitation and force generation on magnetic nanoparticles inside vitreous cavity

open access: yesMathematical Biosciences and Engineering, 2021
The purpose of this manuscript was to design a better method for recovery from rhegmatogenous retinal detachment (RRD) surgery. We attempted to achieve this by designing a helmet that can manipulate intraocular magnetic nanoparticles (MNPs) and create a ...

Crystal Structure of the N112A Mutant of the Light-Driven Sodium Pump KR2

open access: yesCrystals, 2020
The light-driven sodium pump KR2, found in 2013 in the marine bacteria Krokinobacter eikastus, serves as a model protein for the studies of the sodium-pumping microbial rhodopsins (NaRs). KR2 possesses a unique NDQ (N112, D116, and Q123) set of the amino

Assembly of Natively Synthesized Dual Chromophores Into Functional Actinorhodopsin

open access: yesFrontiers in Microbiology, 2021
Microbial rhodopsin is a simple solar energy-capturing molecule compared to the complex photosynthesis apparatus. Light-driven proton pumping across the cell membrane is a crucial mechanism underlying microbial energy production. Actinobacteria is one of

Brain and Retinal Organoids for Disease Modeling: The Importance of In Vitro Blood–Brain and Retinal Barriers Studies

open access: yesCells, 2022
Brain and retinal organoids are functional and dynamic in vitro three-dimensional (3D) structures derived from pluripotent stem cells that spontaneously organize themselves to their in vivo counterparts.

Preoperative electrophysiological characterization of patients with primary macula-involving rhegmatogenous retinal detachment [PDF]

open access: yes, 2018
Purpose: To determine 1) which components of retinal function are impaired after rhegmatogenous retinal detachment, 2) which outer retinal pathways (rod- or cone-driven) are more severely affected, and 3) whether there is concomitant inner retinal ...
