Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Suppression of surface charge accumulation on Al2O3-filled epoxy resin insulator under dc voltage by direct fluorination

AIP Advances, 2015
Surface charge accumulation on insulators under high dc voltage is a major factor that may lead to the reduction of insulation levels in gas insulated devices. In this paper, disc insulators made of Al2O3-filled epoxy resin were surface fluorinated using

Neutron, electron and X-ray scattering investigation of Cr1-xVx near Quantum Criticality [PDF]

, 2014
The weakness of electron-electron correlations in the itinerant antiferromagnet Cr doped with V has long been considered the reason that neither new collective electronic states or even non Fermi liquid behaviour are observed when antiferromagnetism in ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Study on surface charges accumulation characteristics of insulators for ±500 kV DC-GIL based on multi-physics coupling model [PDF]

AIP Advances
When a DC voltage is applied externally, a large amount of charge accumulates on the surface of the insulating components in the gas insulated metal-enclosed transmission line (GIL), significantly reducing the flashover voltage along the surface and ...

Graphene Oxide Addition With Low Fraction Improving Surface Charge Inhibition Performance of Epoxy/SiC Coating Under DC Stress

IEEE Access, 2020
Surface charge accumulation under DC stress is a critical factor in reducing the insulation performance of epoxy-based nanocomposite. Surface coating has been used to inhibit the charge accumulation, but the inhibition mechanism of the coating material ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Evidence of charge carrier number fluctuations in InN thin films? [PDF]

, 2011
Due to its small band-gap and its high mobility, InN is a promising material for a large number of key applications like band-gap engineering for high efficiency solar cells, light emitting diodes, and high speed devices.
