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.

Integrated Design of Cooperative Detection and Guidance Considering Equal Numbers of Aircraft on Both Sides

Aerospace
In the scenario where the number of interceptors is equal to the number of target aircraft, and recognizing that the geometric configuration of interceptors during their maneuver towards targets affects detection effectiveness and guidance accuracy, we ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Changes in physiological parameters and thermal comfort when wearing protective clothing in long-range aeromedical evacuation: a prospective, non-blinded, two-stage crossover self-controlled study

Journal of Physiological Anthropology
Background The thermos-physiological characteristics of medical personnel wearing protective clothing during prolonged activities under low oxygen pressure (LOP) and normal oxygen pressure (NOP) are crucial. Methods The average age of the 24 participants

Solution and Optimization of Aircraft Swarm Cooperating Anti-Stealth Formation Configuration

IEEE Access, 2018
There are many problems in present anti-stealth detection technologies, such as small detection range and excessive detection blind zone. Besides, the stealth target is difficult to be detected and tracked with current technology. To solve these problems,

Force Control of a Space Manipulator

Journal of Robotics and Mechatronics, 2000
This paper deals with the force control of a space manipulator for a sample-return mission. There are two difficulties in force control of this class of space manipulator: One is that a space robot has no fixed point in space and moves when its manipulator exerts force on the environment.

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

FEBS 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 ...

Dual-Channel Induced Countermeasure Strategy for Formation Control of Distributed UAV Swarms with Prescribed Flight Trajectory

Drones
For malicious distributed unmanned aerial vehicle (UAV) swarms operating in civilian airspace, this paper proposes a novel dual-channel induced countermeasure strategy (DCICS) with prescribed countermeasure flight trajectories, in which the designable ...

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.
