Infectious bursal disease virus affecting interferon regulatory factor 7 signaling through VP3 protein to facilitate viral replication.

Interferon regulatory factor 7 (IRF7)-mediated type I interferon antiviral response is crucial for regulating the host following viral infection in chickens. Infectious bursal disease virus (IBDV) is a double-stranded RNA virus that induces immune suppression and high mortality rates in chickens aged 3-6 weeks. Previous studies have shown that IBDV infection antagonizes the type I interferon production to facilitate viral replication in the cell, and IRF7 signaling might play an important role.

Nanomagnetism Triggering Carriers Double-Resistance Conduction and Excellent Flexible Thermoelectrics.

Nanomagnetism may enable electrical conductivity and Seebeck coefficient to be decoupled and can potentially lead to remarkable enhancements in thermoelectric (TE) performance, however, their physical mechanisms have not been explored. Herein, it is shown that the nanomagnetism from Fe and FeO nanoparticles embedded in BiSbTe/epoxy flexible films can lead to the carriers splitting into spin-up and spin-down conductive branches with different resistances and mobilities due to the exchange interaction between the spin of carriers and the nanomagnetism. The double-resistance conduction of carriers may well explain the decoupling of electrical conductivity and Seebeck coefficient and their simultaneous enhancements in the thermo-electro-magnetic flexible films.

Investigating the factors contributing to the maintenance of high levels of warm season nocturnal ozone in a basin city.

HPV E6/E7-Induced Acetylation of a Peptide Encoded by a Long Non-Coding RNA Inhibits Ferroptosis to Promote the Malignancy of Cervical Cancer.

Although a fraction of functional peptides concealed within long non-coding RNAs (lncRNAs) is identified, it remains unclear whether lncRNA-encoded peptides are involved in the malignancy of cervical cancer (CC). Here, a 92-amino acid peptide is discovered, which is named TUBORF, encoded by lncRNA TUBA3FP and highly expressed in CC tissues. TUBORF inhibits ferroptosis to promote the malignant proliferation of CC cells.

Discussion on the Gradation and Interface Effects on the Dynamic Mechanical Behaviors of Hydraulic Concrete Based on Meso-Mechanical Simulation.

Hydraulic concrete is quite different from normal concrete in the terms of aggregate gradation and construction-induced interfaces. To explore their influences on the dynamic mechanical behaviors of hydraulic concrete, several mesoscale numerical models with different aggregate gradations and interfaces were established and subjected to dynamic compressive or tensile loadings. The results show that aggregate gradation significantly affected hydraulic concrete failure patterns under dynamic loads, but interface effects were less obvious, and stressing uniformity improved with an increasing loading rate.
