Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

On Nested Central Configurations of the 3n Body Problem

open access: yesJournal of Nonlinear Science
In this work, we consider the existence of (3, n)–crowns in the classical Newtonian 3n–body problem, which are central configurations formed by three groups of n bodies with the same mass within each group, located at the vertices of three concentric regular polygons.

On central configurations of twisted crowns

open access: yes, 2016
We consider the planar central configurations of the Newtonian $κn$-body problem consisting in $κ$ groups of $n$-gons where all $n$ bodies in each group have the same mass, called $(κ, n)$-crown. We study the location and the number of central configurations when $κ=2$.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Root canal morphology of permanent mandibular incisors of Saudi subpopulation in Al-Baha region: A cone-beam computed tomography study

open access: yesSaudi Endodontic Journal
Introduction: A proper understanding of root canal morphology and its deviations is essential for improving the outcomes of endodontic procedures. Therefore, the current study aims to explore the root canal morphology of permanent mandibular central and ...
