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 ...

Heat Line formation in a roll caster

Applied Scientific Research, 1987
A steady state two dimensional finite difference model has been developed to describe the roll casting process. The model explains the formation of the speed limiting defects called ‘Heat Lines’. The results of subsequent casting speed trials are compared with the predictions made by the numerical model.

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 ...

Molecule-dependent abundance behavior of oxygen-bearing complex organics in high-mass star-forming regions: A uniform 50-source survey

Astronomy & Astrophysics
We present a uniform IRAM-30 m survey analysis of four oxygen-bearing complex organic molecules (COMs) – methanol (CH3OH), acetaldehyde (CH3CHO), methyl formate (CH3OCHO), and dimethyl ether (CH3OCH3) – toward 50 high-mass star-forming regions (HMSFRs ...

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

FEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Unravelling the complex structure of the Fe II emission region in Type 1 active galactic nuclei

Astronomy & Astrophysics
Aims. Using a large sample of Type 1 active galactic nucleus spectra, we investigated the complex structure of the Fe II emission region with the aim of understanding the atomic processes responsible for the enhancement of the Fe II emission. We explored

A Low-mass line-rich Core Found in Massive Star-forming Region IRAS 16351-4722

The Astrophysical Journal, 2023
We present Atacama Large Millimeter/submillimeter Array subarcsecond-resolution observations of both continuum and molecular lines at 345 GHz toward the massive star-forming region IRAS 16351-4722 (hereafter I16351).

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.
