Structural characterization of newt tendon regeneration after complete transection: In vivo two‐photon imaging and transmission electron microscopy

open access: yesJournal of Anatomy, Volume 248, Issue 3, Page 383-394, March 2026.
The present study characterized newt digital flexor tendon regeneration structurally at both micro‐ and nanoscales following complete transection and suggested that the mechanism of tissue regeneration differs between the early phase (until 6 weeks) and the late phase (after 6 weeks). Tendon stubs remained separated for up to 2 weeks after transection,

Histone methyltransferase G9a crosstalks with H3K36 histone methyltransferases NSD3 and SETD2 to mediate gene activation

open access: yesFrontiers in Cell and Developmental Biology
The euchromatic histone methyltransferase G9a/KMT1C/EHMT-II functions as a corepressor and a coactivator of transcription, depending upon its association with distinct protein complexes. While the mechanisms of G9a-mediated repression are well understood,

Loading Mode Dependence of Twin‐Twin Boundary Formation in a Textured Magnesium Alloy

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 4, 17 February 2026.
The structures of twin‐twin boundaries formed by interactions between twin variants sharing the same or different zone axes in a deformed magnesium alloy are demonstrated. Lattice distortion around complicated interfaces promotes grain refinement in the subsequent thermomechanical process, enhancing the mechanical performance of magnesium alloys ...

In Situ Liquid‐Cell Transmission Electron Microscopy Insights Into Lithium‐Ion Battery Materials Degradation: Challenges and Emerging Solutions

open access: yesAdvanced Science, Volume 13, Issue 8, 9 February 2026.
Lithium‐ion battery degradation arises from complex, localized processes during operation, limiting long‐term performance. In situ electrochemical liquid cell TEM provides unique access to these mechanisms. This review summarizes degradation phenomena revealed by liquid cell TEM, traces the evolution of the three main cell designs, compares their ...

A syntactic perspective on rhetorical purpose: The example of if-conditionals in medical editorials [PDF]

open access: yesIbérica, 2014
This paper provides an in-depth analysis of the functioning of if-conditionals in medical editorials (MEDs). As previous genre-based studies of medical discourse genres have shown, MEDs need to address at least three different types of readers and are ...

A smart contract system for decentralized borda count voting [PDF]

open access: yes, 2020
In this article, we propose the first self-tallying decentralized e-voting protocol for a ranked-choice voting system based on Borda count. Our protocol does not need any trusted setup or tallying authority to compute the tally.
