VISULYZE-assisted nomogram optimization enhances astigmatism correction accuracy in keratorefractive lenticule extraction: a stratified retrospective analysis

open access: yesFrontiers in Medicine
BackgroundKeratorefractive lenticule extraction (KLEx) commonly relies on empirical nomogram adjustments to improve refractive accuracy; however, astigmatism correction remains suboptimal.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Emerging experimental and computational methods for studying redox‐regulated structural transitions

open access: yesFEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Estimation of breakage position in wire rope cross-section by geometrical formulation of wire shape

open access: yesNihon Kikai Gakkai ronbunshu, 2022
A wire rope is one of the main components of cranes and elevators. The wires of the rope gradually break with long-term use, and the rope eventually leads to fracture.

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...
