Assembly of soil multitrophic community regulates multifunctionality via multifaceted biotic factors in subtropical ecosystems.

Soil biodiversity underpins multiple ecosystem functions and services essential for human well-being. Understanding the determinants of biodiversity-ecosystem function relationships (BEFr) is critical for the conservation and management of soil ecosystems. Community assembly processes determine community diversity and structure.

State of Health Estimation and Battery Management: A Review of Health Indicators, Models and Machine Learning.

Lithium-ion batteries are a key technology for addressing energy shortages and environmental pollution. Assessing their health is crucial for extending battery life. When estimating health status, it is often necessary to select a representative characteristic quantity known as a health indicator.

Host metabolism balances microbial regulation of bile acid signalling.

Metabolites derived from the intestinal microbiota, including bile acids (BA), extensively modulate vertebrate physiology, including development, metabolism, immune responses and cognitive function. However, to what extent host responses balance the physiological effects of microbiota-derived metabolites remains unclear. Here, using untargeted metabolomics of mouse tissues, we identified a family of BA-methylcysteamine (BA-MCY) conjugates that are abundant in the intestine and dependent on vanin 1 (VNN1), a pantetheinase highly expressed in intestinal tissues.

Xuefu Zhuyu Decoction Improves Blood-Brain Barrier Integrity in Acute Traumatic Brain Injury Rats via Regulating Adenosine.

Objective: To explore the neuroprotective effects of Xuefu Zhuyu Decoction (XFZYD) based on in vivo and metabolomics experiments.

Methods: Traumatic brain injury (TBI) was induced via a controlled cortical impact (CCI) method. Thirty rats were randomly divided into 3 groups (10 for each): sham, CCI and XFZYD groups (9 g/kg).

Annealing Effect on Linear and Ultrafast Nonlinear Optical Properties of BiTe Thin Films.

In recent years, the fabrication of materials with large nonlinear optical coefficients and the investigation of methods to enhance nonlinear optical performance have been in the spotlight. Herein, the bismuth telluride (BiTe) thin films were prepared by radio-frequency magnetron sputtering and annealed in vacuum at various temperatures. The structural and optical properties were characterized and analyzed using X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy, spectroscopic ellipsometry, and UV/VIS/NIR spectrophotometry.
