The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Experimental study on enhancing the foam spray range of compressed air foam nozzle

Journal of Safety Science and Resilience
As the core equipment in power systems, ultra-high voltage (UHV) transformers pose a high fire risk. The compressed-air foam spray nozzle is a novel end-release device that, due to its high efficiency and excellent suppression effect on oil-based fires ...

Alienation Coefficient and Wigner Distribution Function Based Protection Scheme for Hybrid Power System Network with Renewable Energy Penetration

, 2020
The rapid growth of grid integrated renewable energy (RE) sources resulted in development of the hybrid grids. Variable nature of RE generation resulted in problems related to the power quality (PQ), power system reliability, and adversely affects the ...

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 ...

Effect of oil immersion on the horizontal flame spread over transformer insulating paperboard with different sizes

Case Studies in Thermal Engineering
Transformer oil and insulating paperboard are widely used in oil-immersed transformers and may be ignited in the event of device failure. The present study aims to investigate the effect of oil immersion on the horizontal flame spread over the ...

Analysis of Distribution Network Protection Based on Distributed Power Sources

IOP Conference Series: Materials Science and Engineering, 2018
After a distributed power supply is connected to a distribution network, the distribution network changes from a single-supply radiant network to a network. When a fault occurs in the distribution network, the size and direction of the short - circuit current will change, giving rise to conventional relay protection. Normal operation brings a series of

Adenosine‐to‐inosine editing of miR‐200b‐3p is associated with the progression of high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
A‐to‐I editing of miRNAs, particularly miR‐200b‐3p, contributes to HGSOC progression by enhancing cancer cell proliferation, migration and 3D growth. The edited form is linked to poorer patient survival and the identification of novel molecular targets.
