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.

Effects of DC-Current for Short-Time Negative Sequence Current of Synchronous Machine
IEEJ Transactions on Industry Applications, 2001 When a line-to-lire short-circuit occurs, the positive-sequence-, the negative-sequence-and the DC-current flow in the armature winding of synchronous machine. The negative-sequence current is limited in JEC-114, as this current causes the induced current and the overheat on the surface of the rotor.

FEBS 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 ...

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Performance of generator negative-sequence protection during single-phase fault [PDF]
, 2012 Negative-sequence current is a component that resulted from unbalance conditions that occur in the system. Theoretically, problems caused by the negativesequence current are rare and can be ignored, but in reality the presence of negative sequence ...

Reassessment of Permissible Negative Sequence Current for Power Plant Operation of Taipower
Energy and Power Engineering, 2010 The N3 power plant of Taipower is located in the southern tip of Taiwan and connected to the power pool by four out-linking 345-kV overhead transmission circuits. There are two 951-MW generators. Each generator occupied 11% of the system peak load in 1985 when the generator was in commercial operation.

Turn-to-turn fault detection in transformers using negative sequence currents [PDF]
2011 IEEE Electrical Power and Energy Conference, 2011 This paper presents a new, simple and efficient protection technique which is based on negative sequence currents. Using this protection technique, it is possible to detect minor internal turn-to-turn faults in power transformers. Also, it can differentiate between internal and external faults.

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.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
