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 ...

Assessment of residual stress using thermoelastic stress analysis [PDF]

, 2011
The work described in this thesis considers the application of thermoelastic stress analysis (TSA) to theassessment of residual stresses in metallic materials. Residual stresses exist within almost all engineeringcomponents and structures.

Oxidative Stress Monitoring: Needs and Opportunities [PDF]

Oxidative stress is characterized by the diminished capacity of a biological system to overcome the overproduction of reactive species (RS) and free radicals (FR). This process has been related to the pathogenesis of virtually every disease.

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

Enhancing drought tolerance in Cannabis sativa L. by Trichoderma hamatum through optimized water usage

Current Plant Biology
Drought stress in hemp (Cannabis sativa L.) is exacerbated by climate change, posing significant abiotic challenges. Trichoderma hamatum, known for mitigating abiotic stresses, was evaluated for its effects on hemp under drought conditions.

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.

Influence of T-stress on fatigue crack propagation

, 2015
Mechanical components of aircraft may suffer from shocks and scratches during their and assembly. Under service, these structures are subjected to fatigue loading. This might lead to the initiation of micro-cracks, which will propagate, and in the worst cases, the fracture of the component might occur.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...
