    Abstract The extensive use of plastics has given rise to microplastics, a novel environmental contaminant that has sparked considerable ecological and environmental concerns. Biodegradation offers a more environmentally friendly approach to eliminating microplastics, but their degradation by marine microbial communities has received little attention. In this study, we used iron-enhanced marine sediment to augment the natural bacterial community and facilitate the decomposition of polyethylene (PE) microplastics. The introduction of iron-enhanced sediment engendered an augmented bacterial biofilm formation on the surface of polyethylene (PE), thereby leading to a more pronounced degradation effect. This novel observation has been ascribed to the oxidative stress-induced generation of a variety of oxygenated functional groups, including hydroxyl (-OH), carbonyl (-CO), and ether (-C-O) moieties, within the microplastic substrate. The analysis of succession in the community structure of sediment bacteria during the degradation phase disclosed that Acinetobacter and Pseudomonas emerged as the principal bacterial players in PE degradation. These taxa were directly implicated in oxidative metabolic pathways facilitated by diverse oxidase enzymes under iron-facilitated conditions. The present study highlights bacterial community succession as a new pivotal factor influencing the complex biodegradation dynamics of polyethylene (PE) microplastics. This investigation also reveals, for the first time, a unique degradation pathway for PE microplastics orchestrated by the multifaceted marine sediment microbiota. These novel insights shed light on the unique functional capabilities and internal biochemical mechanisms employed by the marine sediment microbiota in effectively degrading polyethylene microplastics.

    Abstract China, known as the largest carbon emitter and the second largest economy worldwide, has continued to put effort into the understandings of the main drivers of carbon emission and their decoupling statuses from its economic growth. Considering the significant differences of natural and social environments in different regions of China, this paper presents a regional-scale decomposition of energy-related carbon emission and its decoupling from economic growth by using the Logarithmic Mean Divisia Index (LMDI) and the Tapio decoupling method. The decoupling results indicate that carbon emissions in all regions show a stable decoupling trend from their economic development, which means that China is now on the right road for achieving a low-carbon economy. However, the decoupling status by the end of 2016 also indicates that most of the regions are still in the states of expansive coupling or weak decoupling, especially in Northwest (NW), which implies that the speed of decarbonization process is still not high enough. The decomposition results show that in all regions except NW, GDP per capita is the most influential factor leading to increasing carbon emissions, while energy intensity is the largest factor in reducing carbon emissions. In NW, both GDP per capita and energy intensity drive the increase in carbon emissions. The results in this paper could benefit China's regional policy-making and national strategies.

    Abstract Bisphenol A (BPA), a typical endocrine disruptor and a contaminant of emerging concern (CECs), has detrimental impacts not only on the environment and ecosystems, but also on human health. Therefore, it is essential to investigate the degrading processes of BPA in order to diminish its persistent effects on ecological environmental safety. With this objective, the present study reports on the effectiveness of biotic/abiotic factors in optimizing BPA removal and evaluates the kinetic models of the biodegradation processes. The results showed that BPA affected chlorophyll a, superoxide dismutase (SOD) and peroxidase (POD) activities, malondialdehyde (MDA) content, and photosystem intrinsic PSII efficiency (Fv/Fm) in the microalga Chlorella pyrenoidosa, which degraded 43.0 % of BPA (8.0 mg L

    Abstract During coal mining, the unsynchronized flexures of the overlying burdens that have different hardnesses and thicknesses can cause the formation of bed separation spaces in which a large amount of water can accumulate from the surrounding aquifers; this water can be stored. The impact of mining-induced bed separation spaces on a Cretaceous aquifer over water-conducting fractured zones was studied at the Yinpanhao coal mine in the Ordos Basin, China. In situ tests of the hydraulic variation were conducted using four fiber Bragg grating sensors and the strata movement was measured using 60 magnetic loops anchored at different horizons in two boreholes drilled over an active mining panel. Three bed separation spaces in the Cretaceous strata were identified at depths of about 285, 401, and 435 m, respectively. Controlled by the development of the bed separation spaces, the hydraulic variation in the Cretaceous aquifer was divided into four stages. With the approach of the mining face, the bed separation spaces extended horizontally to the vicinity of the monitoring holes which resulted in a rapid decrease of the hydraulic head. Due to the long suspending distance of the upper strata, the sudden fracture of the strata caused the closure of the lower bed separation space and an increase in the volume of the upper bed separation space, inducing an abrupt and dramatic drop of the hydraulic head of the upper aquifers in the Cretaceous strata. These test results were verified with long-term monitoring data on the hydraulic variation in different aquifers.

    Abstract Hydration of fat-free mass (FFM), defined as the ratio of total body water (TBW) to FFM (TBW/FFM), is stable at 0.739 in adult mammals. However, an increase in the TBW/FFM ratio is common in hemodialysis (HD) patients. This study aimed to evaluate the determinants of TBW/FFM and investigate its predictive value for the prognosis of all-cause mortality in HD patients. We enrolled patients undergoing maintenance HD between July 2020 and May 2021. All patients were prospectively followed until death, HD dropout, or until the end of the study (November 1, 2021). A forward stepwise multivariable linear regression analyses was performed to test the independent relationship between TBW/FMM and other clinical variables. Receiver operating characteristic (ROC) analysis was used to discriminate the TBW/FFM with respect to 180-day mortality. Of the 106 patients, 42 had elevated TBW/FFM levels. Multiple linear regression analysis revealed that the TBW/FFM ratio was significantly associated with extracellular water (ECW)/TBW (standardized regression coefficient [β = 1.131, P < .001], phase angle (PhA) [β = 0.453, P < .001], and sex (β = 0.440, P < .001). We calculated the ROC curve (AUC) of TBW/FFM, ECW, ECW/TBW, and intracellular water (ICW) to compare the discriminatory capacities of these parameters in predicting 180-day mortality. The AUC for TBW/FFM (AUC = 0.849; 95% CI, 0.745-0.953) exhibited better discriminatory potential than ECW (AUC = 0.562; 0.410-0.714), although it had a similar predictive potential as the ECW/TBW ratio (AUC = 0.831; 0.731-0.932). High TBW/FFM can be used as a valuable prognostic index for predicting all-cause mortality in patients on HD.

    Abstract Inflammatory bowel disease (IBD) is a worldwide issue, and the increased incidence has brought a heavy burden to patients and society. Gut microbiota is involved in the pathogenesis of IBD, and targeting the microbiota, such as probiotics, has emerged as a potential therapy for the treatment of IBD. Here, the effect of Bifidobacterium animalis ssp. lactis LKM512 (LKM512), an anti-aging probiotic, on dextran sulfate sodium salt (DSS)-induced IBD in larval zebrafish was determined. Supplementation of LKM512 promoted the survival rate of the larvae, together with increased locomotor activities and body length. In addition, LKM512 treatment enhanced mucus secretion and alleviated intestinal injury, and these results were associated with the upregulation of mucin-related and downregulation of inflammatory markers. Moreover, LKM512 increased the diversity of the microbiota and ameliorated the dysbiosis by increasing the abundance of Bacteroidetes and Firmicutes and reducing the abundance of Proteobacteria. Specifically, the abundance of beneficial bacteria, including the short-chain fatty-acids (SCFAs)-producing genera Lachnospiraceae_NK4A136_group, Muribaculaceae, and Alloprevotella, was increased by LKM512, while the abundance of harmful genera, such as Pseudomonas, Halomonas, and Escherichia-Shigella, was reduced by LKM512. Consistent with these findings, the microbial functions related to metabolism were partly reversed by LKM512, and importantly, fermentation of short-chain fatty acids-related functions were enhanced by LKM512. Therefore, LKM512 might be one potential probiotic for the prevention and treatment of IBD, and further studies that clarify the mechanism of LKM512 would promote the application of LKM512.
