Unraveling the active site cover of coproheme decarboxylase from Listeria monocytogenes

The FEBS Journal, EarlyView.
During heme biosynthesis in Gram‐positive bacteria, coproheme decarboxylase (ChdC) catalyzes the conversion of four‐propionate substrate coproheme to the two propionate product heme b. Its active site is universally covered by a flexible linking loop. This study identifies an important histidine residue, which stabilizes the loop in a ChdC homolog.

Lightning Protection against Winter Lightning

IEEJ Transactions on Power and Energy, 2007
Winter lightning, which occurs along the Sea of Japan coast, often damages transmission lines and distribution lines with the conventional lightning protection. These lines in mountainous areas suffer extensive damage from winter lightning. It is very important to investigate the features of lightning outages in detail to improve the lightning ...

Two Faces of the Anti‐Inclusion Neoconservative Coin in Brazil: Neoliberalism and Far‐Right

Gender, Work &Organization, EarlyView.
ABSTRACT Brazil has recently experienced the resurgence of the far‐right, a movement that has also occurred in other countries around the world. Given this context, this article seeks to understand the factors that enabled the union among neoliberalism, neoconservatism, and the far‐right in Brazil, demonstrating that in times of economic crisis the ...

Prediction of Breakdown Voltage of Long Air Gaps Under Switching Impulse Voltage Based on the ISSA-XGBoost Model

Energies
In transmission lines, the discharge characteristics of long air gaps significantly influence the design of external insulation. Existing machine learning models for predicting breakdown voltage are typically limited to single gaps and do not account for

Assessment of the lightning transient coupling to control cables interconnecting structures in large industrial facilities and power plants

, 2005
Large industrial facilities and power plants often require a huge number fo information and control cables between the differnet structures. These I&C-cables can be routed in reinforced concrete cable ducts or in isolated buried cable runs.

Indirect lightning performance of a real distribution network with focus on transformer protection

, 2014
The paper applies the Monte Carlo procedure proposed by the Authors to evaluate the indirect lightning performance of a real medium-voltage distribution network, which includes feeders and laterals, poles, secondary substations and surge protection ...

Hypoxia‐preconditioned adipose‐derived mesenchymal stem cells‐derived exosomes transferring H19 obstruct neutrophil extracellular traps formation via HOXA5‐mediated inactivation of TLR4/NF‐κB/NLRP3 inflammatory signaling

Journal of Diabetes Investigation, EarlyView.
In this study, we uncovered that Hypo‐Exo transferring H19 promoted diabetic wound healing by repressing NETs formation via the miR‐130a/b‐3p/HOXA5 pathway to inactivate the TLR4/NF‐κB/NLRP3 inflammatory signaling. ABSTRACT Background Hypoxia‐stimulated adipose‐derived mesenchymal stem cells (ADSCs)‐derived exosomes (Hypo‐Exo) have a positive impact on

Refined risk assessment and differentiated protection of lightning damage in distribution network lines considering the underlying surface environment

Frontiers in Energy Research
The distribution line is widely distributed and the span of pole-towers is small. However, the existing lightning positioning system has limited positioning accuracy, and the lightning strike coordinates it locates have certain deviations for the ...

Quality Regulation and Unexpected Gaming: Evidence From Mandating Flight Delay Compensation

Journal of Economics &Management Strategy, EarlyView.
ABSTRACT Policies that target a single aspect of agents' motivation may lead to their diminished efforts in other areas. This paper examines the effect of the European Union's flight delay compensation policy on flight on‐time performance by exploiting a unique policy variation in a difference‐in‐differences framework.
