FEBS Open Bio, EarlyView.Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes
FEBS Open Bio, EarlyView.Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Triple buck converter – an efficient low-distortion switch-mode power amplifier topology
The Journal of Engineering, 2019 A switch-mode power amplifier topology that can achieve both a high conversion efficiency and low-output signal distortion is introduced. Such systems are desirable for ultra-high precision amplifiers that, for example, drive actuators in nanometre ...

Computer-aided simulation of power MOSFET switch-mode convertors
Electronics Letters, 1984 A computer-aided modelling procedure for power MOSFET switching convertors is reported. Results show dynamic turn-on and turn-off device waveforms, peak stresses, switching trajectory and transient switching losses. Excellent agreement is demonstrated between predicted and measured switching characteristics on an experimental high-frequency high ...

Protocol for quantifying miRNA trafficking across the endosomal membrane
FEBS Open Bio, EarlyView.An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

Heterotropic regulation and negative homotropic cooperativity
FEBS Open Bio, EarlyView.We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.
