Enhancing single-stage partial nitritation-anammox process with airlift inner-circulation and oxygen partition: a novel strategy for treating high-strength ammonium wastewater.

In the single-stage partial nitritation-anammox process for high-ammonium wastewater treatment, the presence of sufficient biomass with high activity is essential. This study developed an innovative airlift inner-circulation partition bioreactor (AIPBR) with a dual-cylinder structure. During the 362 days' operation, the AIPBR exhibited robust and stable nitrogen removal performance under diverse influent ammonium spanning from 300 to 1800 mg N/L.

Precipitation changes reshape desert soil microbial community assembly and potential functions.

Understanding the responses of desert microbial communities to escalating precipitation changes is a significant knowledge gap in predicting future soil health and ecological function. Through a five-year precipitation manipulation experiment, we investigated the contrasting eco-evolutionary processes of desert bacteria and fungi that manifested in changes to the assembly and potential functions of the soil microbiome. Elevated precipitation increased the alpha diversity and network complexity of bacteria and fungi, proportion of non-dominant phyla, and abundance of carbon- and nitrogen-fixing bacteria and saprophytic, symbiotic, and pathogenic fungi.

Estimating wastewater emissions and environmental levels of typical organic contaminants based on regionalized modelling.

Organic contaminants (OCs) are released into the environment through effluent discharges from wastewater treatment plants (WWTP), posing risks to environment health. However, emissions from various source, particularly large-scale investigations across different industries, remain poorly understood. Based on both sampling and statistical data, this study estimates the emissions of 10 OCs, including perfluorooctane acid (PFOA), perfluorooctane sulfonate (PFOS), 4-nonylphenol (4-NP), 4-tert-octylphenol (4-t-OP), dibutyl phthalate (DBP), di-iso-butyl phthalate (DIBP), dimethyl phthalate (DMP), butyl benzyl phthalate (BBP), di(2-ethylhexyl) phthalate (DEHP), and bisphenol A (BPA), from the effluents of 160 factories across 8 industries, 541 municipal wastewater treatment plants (MWWTPs), and 8 waste treatment plants (WTPs) in the upper Yangtze River Basin.

Comprehensive evaluation of low-carbon cementitious materials prepared with industrial by-product calcium carbide residue (CCR) as alkali source.

The preparation of low-carbon cementitious materials through the synergistic coupling of multiple solid wastes has great potential for development, which can improve the problems of resource shortage and environmental pollution. In this paper, a new type of supersulfated cement was developed by using calcium carbide residue (CCR) as an alkaline activator. The effects of CCR content on the mechanical properties and hydration behaviors of the samples under steam curing conditions were discussed.

Impacts of aquaculture on nitrogen cycling and microbial community dynamics in coastal tidal flats.

The expansion of aquaculture areas has encroached upon vast areas of coastal wetlands and introduced excessive nitrogen inputs, disrupting microbial communities and contributing to various environmental issues. However, investigations on how aquaculture affects microbial communities and nitrogen metabolism mechanisms in coastal tidal flats remain scarce. Hence, we explored the composition, diversity, and assembly processes of nitrogen-cycling (N-cycling) microbial communities in tidal flats in Jiangsu using metagenomic assembly methods.

HMGB1-mediated macrophage regulation of NF-κB activation and MMP3 upregulation in nucleus pulposus cells: A critical mechanism in the vicious cycle of intervertebral disc degeneration.

Intervertebral disc degeneration (IVDD) is a leading cause of low back pain, primarily driven by inflammatory processes within the disc, particularly involving the infiltration and activity of macrophages. High Mobility Group Box 1 (HMGB1) has been identified as a crucial mediator in this inflammatory cascade, yet its precise role in macrophage-induced disc degeneration remains unclear. In this study, we employed a combination of in vivo and in vitro models, including genetically engineered mice with macrophage-specific overexpression of HMGB1, a rat model of IVDD, and cultured macrophages and nucleus pulposus cells (NPCs), to elucidate the role of HMGB1 in IVDD.

Serum KNG and FVIII may serve as potential biomarkers for depression.

BarH1 regulates the expression of conserved odorant-binding protein 22 from Dastarcus helophoroides.

Chemical signals are pivotal in establishing tritrophic interactions among host plants, herbivorous insects, and natural enemies. Previous studies have shown that evolutionarily conserved MaltOBPs in Monochamus alternatus and DhelOBPs in Dastarcus helophoroides contribute to the establishment of pine -pest - natural enemy tritrophic interactions by recognizing the same volatile emitted by the host during crucial developmental stages. We hypothesized that the transcriptional regulatory mechanisms of evolutionarily conserved OBPs respectively from pests and enemies are similar.
