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.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Unsupervised motion segmentation of image sequences using adaptive filtering

open access: yes, 2022
S.451-454 : Lit.In this paper we present a new method for feature extraction in unsupervised motion segmentation of image sequences. This method is based on the multichannel filtering of the input image sequence using adapted Gabor filters.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Multiple dim targets detection in infrared image sequences

open access: yes, 2014
Strong noises interference is a difficult technical problem for signals detection. Multiple targets detection with strong noises makes the problem more complicated.

Mosaicing of multiplanar regions through autonomous navigation of off-the-shelf quadcopter

open access: yesIET Cyber-systems and Robotics, 2019
The real world is made up of multiplanar and curved surfaces. Imaging such surfaces with an orthographic view using a handheld camera is tiring if the scene encompasses a view larger than the camera field of view.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

A microarray image gridding method based on image projection difference sequences analysis and local extrema searching

open access: yes, 2012
Microarray image gridding is one important step of microarray image analysis to determine 2D image coordinates of all array spots in the hybridized gene chip image.

Segmentation-assisted detection of dirt impairments in archived film sequences

open access: yes, 2007
A novel segmentation-assisted method for film dirt detection is proposed. We exploit the fact that film dirt manifests in the spatial domain as a cluster of connected pixels whose intensity differs substantially from that of its neighborhood and we ...
