LAMTOR1/mTORC1 promotes CD276 to induce immunosuppression via PI3K/Akt/MMP signaling pathway in Clostridium perfringens-induced necrotic enteritis of laying hens.

Clostridium perfringens (C. perfringens) causes avian necrotic enteritis, leading to huge economic losses to the poultry industry. This pathogen induces host immunosuppression; however, the molecular mechanism is still unclear.

G band enhancement in ABt-twisted trilayer graphene.

G band, originating from the in-plane vibrations of carbon atoms, is the main signature in Raman spectroscopy of graphene-based systems. It is often used to characterize the sample quality and obtain molecular vibration information. Here we investigate the Raman spectroscopy of ABt-twisted trilayer graphene (ABt-TTG) and observe two enhancement centers for the G band across samples with different twist angles.

Baicalin attenuates PD-1/PD-L1 axis-induced immunosuppression in piglets challenged with Glaesserella parasuis by inhibiting the PI3K/Akt/mTOR and RAS/MEK/ERK signalling pathways.

Infection of piglets with Glaesserella parasuis (G. parasuis) induces host immunosuppression. However, the mechanism underlying the immunosuppression of piglets remains unclear.

Baicalin and probenecid protect against Glaesserella parasuis challenge in a piglet model.

Glaesserella parasuis (G. parasuis) induces vascular damage and systemic inflammation. However, the mechanism by which it causes vascular damage is currently unclear.

Dicarbon nitride and Janus transition metal chalcogenides van der Waals heterojunctions for photocatalytic water splitting.

Two-dimensional graphene-like dicarbon nitride (CN) is a newly synthesized metal-free material, which has attracted significant research interest owing to the direct band gap, high carrier mobility, thermal stability, and great tunable properties. However, their application in photocatalytic water splitting has not been well explored. In this work, the properties of photocatalytic water decomposition in heterojunctions composed of CN and transition metal dichalcogenides (TMDs) with Janus structure MoXY (X, Y = S, Se, Te) are systematically studied by the first-principles calculations based on density functional theory.

Tuning the Thermal Transport of Hexagonal Boron Nitride/Reduced Graphene Oxide Heterostructures.

Tuning the thermal properties of materials is considered to be of crucial significance for improving the performance of electronic devices. Along these lines, the development of van der Waals (vdW) heterostructures becomes an effective solution to affect the thermal transport mechanisms. However, vdW interactions usually block phonon transport, which leads to a reduction in thermal conductivity.

Photothermal-Transport Imaging and Thermal Management of 2D Materials.

Thermal management plays an important role in miniaturized and integrated nanoelectronic devices, where finding ways to enable efficient heat-dissipation can be critical. 2D materials, especially graphene and hexagonal boron nitride (h-BN), are generally regarded as ideal materials for thermal management due to their high inherent thermal conductivity. In this paper, a new method is reported, which can be used to characterize thermal transport in 2D materials.

Optimization of grating duty cycle in non-interferometric grating-based X-ray phase contrast imaging.

Grating-based X-ray phase contrast imaging technology is one of the most potential imaging methods in real applications. It can be classified into two categories: interferometry and non-interferometric imaging. The non-interferometric grating-based X-ray phase contrast imaging (NIGPCI) instrument has a great advantage in the forthcoming commercial applications for the flexible system design and the use of large periodic gratings.

A modified equally sloped algorithm based on the total variation algorithm in computed tomography for insufficient data.

Computed tomography (CT) has become an important technique for analyzing the inner structures of material, biological and energy fields. However, there are often challenges in the practical application of CT due to insufficient data. For example, the maximum rotation angle of the sample stage is limited by sample space or image reconstruction from the limited number of views required to reduce the X-ray dose delivered to the sample.
