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

FEBS 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 ...

Comparing speaker-based and observer-based measures of the perception of physical tension during stuttering [PDF]

, 2013
People who stutter commonly experience increased levels of physical tension during moments of stuttering. These increased levels of physical tension have been shown to vary in location of the body and from individual to individual (Brutten & Shoemaker ...

Biophysical approaches for studying viral entry

FEBS 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

Velocity-Sensorless Decentralized Tension Control for Roll-to-Roll Printing Machines

IEEE Access, 2020
This paper presents a velocity-sensorless decentralized tension control scheme without true machine parameter dependence for roll-to-roll printing machines. Both the nonlinear nature and parameter uncertainties are taken into account the development task.

Applying Modified MIMO DIVSC to Synchronism and Tension Control of Dual Motor Systems

, 2014
[[abstract]]In industrial manufacturing systems, one or more client motors are often arranged to follow the velocity of the master motor. The speed difference between these motors will affect the tension of the product.

The human gut microbiome across the life course

FEBS 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.

Tension-controlled suburethral synthetic sling versus standard sling in the treatment of female stress urinary incontinence: preliminary short-term results

Вестник урологии
Introduction. Suburethral sling surgery has been successfully used for the treatment of female urinary incontinence (UI) for several decades. In addition to high efficacy, there are unresolved problems associated with the high recurrence rate of UI and ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS 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.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

FEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified
