An osteoblast-like cell line derived from mice expressing FRET-based tension sensor reveals cellular tension increase during osteogenic differentiation

Biochemistry and Biophysics Reports
Mechanical stimuli significantly influence bone remodeling, although the detailed molecular mechanisms involving changes in intracellular tension during osteoblast differentiation remain unclear. The present study was performed to investigate the role of

Investigation on the Influence of Microstructure Based on Hydrogen Bonding on Surface Tension by Raman Spectroscopy

International Journal of Analytical Chemistry, 2019
Surface tension and Raman spectra containing hydrogen bonding in acetonitrile aqueous solutions with different mole ratios were obtained. Varied surface tension and hydrogen bonding in the mixed solution were discussed.

On the surface tension of directed linear polymers

Journal de Physique, 1989
The directed polymer model on a two- and three-dimensional lattice in the presence of infinite boundary is solved in the free fermion approximation. The excess surface free energy fs is studied in a wide range of the polymer density p. It is shown that fs ∼ ρ2 for d = 2 and fs ∼ ρ 3/2 for d = 3 when p is small. The law ρ3/2 coincides with that obtained

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.

A COMPARISON OF TESTING METHODS FOR DETERMINATION OF SPRAYED CONCRETE TENSILE STRENGTH

Acta Polytechnica CTU Proceedings, 2019
Sprayed concrete is important construction material in tunnelling. Primary lining is essential in NATM where the sprayed concrete can be loaded by tension due to bending moments.

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
