Assessing the spatial differentiation characteristics of soil organic carbon (SOC) in cultivated land in major grain-producing areas is important for regional cultivated land quality management and national food security. We investigated 519 soil profiles of cultivated land in Hebei Province (0-120 cm equally divided into six layers), and obtained 2961 samples. We used geostatistical methods and spatial exploratory analysis to reveal the spatial distribution pattern of SOC in cultivated land in Hebei Province and the impacts of climate, topography, geomorphology, soil properties, and anthropogenic use on the spatial distribution of SOC in cultivated land soils.

While thorough investigations have been carried out on the individual environmental effects of PFU, study on comprehensive environmental effects of PFU and the spatial inequity issues stemming from the transfer of these effects are scarce. This study aims to quantify the greenhouse gas emissions (GHGE), nitrogen emissions (NE), and water consumption (WC) linked to PFU in China from 2000 to 2020.

Ferroptosis characterized by iron-dependent regulated cell death has significant involvement in AKI pathogenesis. As symptomatic treatment of AKI remains clinically limited, a new class of effective therapies has emerged, which is referred to as nanozyme.

After successfully constructing ZnTA, we proceeded to examine its effect on ROS accumulation, cellular ferroptosis and apoptosis, as well as injury severity. Malondialdehyde, Fe amounts and 4-HNE staining demonstrated that ZnTA effectively attenuated rTEC ferroptosis.

Our previous study revealed that nuclear FMR1 interacting protein 1 (NUFIP1), a specific ribophagy receptor, can alleviate T cell apoptosis in sepsis. Yet, the effect of NUFIP1-engineered exosomes elicited from human umbilical cord blood mesenchymal stem cells (hUMSCs) on nerve injury induced by propofol remains unclear.

Nevertheless, the impact of alpha-lipoic acid (α-LA, LA) on fried food-induced autism-like behavior remains unclear. This study aimed to explore how LA affects autism-related behavior and cognitive deficits caused by acrylamide in mice, a representative food hazard found in fried foods.

However, the effect of LR on obesity-associated cognitive impairment remains unclear. The present study found that an 8-week LR dramatically improved high-fat diet (HFD)-induced cognitive decline by preventing synaptic dysfunction, increasing the expressions of neurotrophic factors, and inhibiting neuroinflammation in memory-related brain regions.

The gut microbiome exhibits diurnal rhythmicity in composition and function, and this, in turn, drives oscillations in host metabolism. High-fat diet (HFD) strongly altered microbiome diurnal rhythmicity, however, the role of microbiome diurnal rhythmicity in mediating the improvement effects of MR on obesity-related metabolic disorders remains unclear.

Yb 1000 nm and Er 1536 nm emission can be efficiently sensitized by broadband absorption of Cr in almost the whole visible region in LaGaNbO(LGNO): Cr, Ln (Ln = Yb, Er) phosphor. Between the two kinds of Cr sites, tetrahedral Cr(II) mainly behaves as the broadband sensitizer for Er or Yb. Meanwhile octahedral Cr(I) may energy transfer (ET) to Cr(II), thereby influences the luminescence decay of Cr(II) as increasing Er or Yb content.
