Electron Itinerancy Mediated by Oxygen Vacancies Breaks the Inert Electron Chain to Boosts Lithium-Oxygen Batteries Electrocatalysis.

The complex interaction between dopants and oxygen vacancies (Vo) in metal oxides is crucial for enhancing the adsorption and electron transfer processes of Li-O2 batteries. However, the synergetic mechanism among Vo, dopants, and the host matrix remains unclear. Herein, Ru single-atom-modified TiO2 nanorod (Ru1-TiO2-x) with abundant Vo were fabricated, serving as an efficient catalyst for Li-O2 batteries.

Serum A20 level is associated with bone mineral density in male patients with type 2 diabetes mellitus.

Background: A20, also known as TNF-α-induced protein 3 (TNFAIP3), is a crucial negative regulator of inflammation and immune responses. Emerging evidence suggests that A20 is involved in the regulation of glucose metabolism and plays a significant role in bone metabolic diseases by inhibiting nuclear factor (NF)-κB activation. However, the potential relationship between serum A20 level and bone mineral density (BMD) in patients with type 2 diabetes mellitus (T2DM) has not been explored.

Investigation of the Noise Emitted from Elevated Urban Rail Transit Paved with Various Resilient Tracks.

Based on the dynamic receptance method, a vehicle-track-bridge interaction model was developed to calculate the wheel-rail interaction forces and the forces transmitted to the bridge in an elevated urban rail transit system. A prediction model integrating the finite element method-boundary element method (FEM-BEM) and the statistical energy analysis (SEA) method was established to obtain the noise from the main girder, track slab, and wheel-rail system for elevated urban rail transit. The calculated results agree well with the measured data.

Encodes an RNase E/G-Type Endoribonuclease Required for Chloroplast Development and Seedling Growth in Rice.

Chloroplast biogenesis is a crucial biological process in plants. Endoribonuclease E (RNase E) functions in the RNA metabolism of chloroplast and plays a vital role for chloroplast development in . However, despite sharing 44.

NAD Promotes Superovulation of Huaxi Cattle Through Regulation of Cumulus Cell Proliferation and Oocyte Maturation.

Superovulation and embryo transfer are key technologies to improve the reproductive ability of female animals and enhance the efficiency of livestock production. However, poor-quality oocytes or abnormal fluctuations of hormone levels caused by superovulation affect the embryonic development environment, which may lead to a significant decline in the number and quality of transferable embryos, thus reducing the efficiency of superovulation. In this study, nicotinamide adenine dinucleotide (NAD) was injected into Huaxi cows during the superovulation period to observe the proliferation and apoptosis of transplanted embryos.
