    Abstract Background: Alginate oligosaccharide (AOS) has been reported to exert a crucial role in maintaining the intestinal mucosal barrier (IMB) function. The current study aimed at ascertaining the protective effects of AOS on aging-induced IMB dysfunction and to elucidate the underlying molecular mechanisms.
    Methods: An aging mouse model and a senescent NCM460 cell model were established using d-galactose. AOS was administered to aging mice and senescent cells, and IMB permeability, inflammatory response and tight junction proteins were assessed. In silico analysis was conducted to identify factors regulated by AOS. Using gain- and loss-of-function approaches, we evaluated the roles of FGF1, TLR4 and NF-κB p65 in the aging-induced IMB dysfunction and NCM460 cell senescence.
    Results: AOS protected the IMB function of aging mice and NCM460 cells by reducing permeability and increasing tight junction proteins. In addition, AOS up-regulated FGF1, which blocked the TLR4/NF-κB p65 pathway, and identified as the mechanism responsible for the protective effect of AOS.
    Conclusion: AOS blocks the TLR4/NF-κB p65 pathway via inducing FGF1, ultimately reducing the risk of IMB dysfunction in aging mice. This study highlights the potential of AOS as a protective agent against aging-induced IMB disorder and provides insight into the underlying molecular mechanisms.

    Abstract The spatiotemporal pattern of sediment yield is critical for the management of mega cascade reservoirs in the Lower Jinsha River Basin (LJRB), despite that the scarcity of information has limited our knowledge. This study used a stepwise statistical approach to determine the synergistic factors controlling sediment yield, and relevant models were established to provide predictions for ungauged areas in the mountainous basin. Existing observations for 18 catchments (10²–10⁴ km²) displayed an imbalanced distribution pattern of specific sediment yield (SSY = 83–1269 t km⁻² a⁻¹) in the LJRB, while 6 combinations of local characteristics were found to properly explain the variability (63–92%). The synthesis of temperature, slope proportion, and drainage area exhibited the most explanatory power, where the temperature factor appeared to exert the dominant effect on SSY. This study has effectively simplified the redundant factor dataset by multivariate and partial correlation methods, lowering the bar for modeling analysis. Predictions have been made to present full distribution patterns of sediment yield in the LJRB, characterized by high yields in the middle (cold and steep) and low yields at both ends (warm and flat). This enabled us to detect considerable ungauged areas with abundant sediment yields between cascade reservoirs Xiluodu and Baihetan. Regionalized SSY has decreased by 10–71% over the past 50 years, associating with the superior vegetation condition in response to rising temperatures. Moreover, 2050 projections via two extreme Shared Socioeconomic Pathways (SSP119 and SSP585) suggested that regionalized SSY would continue to decrease by 32–51% on average. The current assessment and future prediction of sediment yield in the LJRB should be useful for engineering purposes, and the proposed modeling approach can provide reference for upper lands and mountainous basins.

    Abstract Macrolides, lincosamides, and streptogramin B (MLS) are structurally distinct molecules that are among the safest antibiotics for prophylactic use and for the treatment of bacterial infections. The family of erythromycin resistance methyltransferases (Erm) invariantly install either one or two methyl groups onto the N6,6-adenosine of 2058 nucleotide (m6A2058) of the bacterial 23S rRNA, leading to bacterial cross-resistance to all MLS antibiotics. Despite extensive structural studies on the mechanism of Erm-mediated MLS resistance, how the m6A epitranscriptomic mark affects ribosome function and bacterial physiology is not well understood. Here, we show that Staphylococcus aureus cells harboring m6A2058 ribosomes are outcompeted by cells carrying unmodified ribosomes during infections and are severely impaired in colonization in the absence of an unmodified counterpart. The competitive advantage of m6A2058 ribosomes is manifested only upon antibiotic challenge. Using ribosome profiling (Ribo-Seq) and a dual-fluorescence reporter to measure ribosome occupancy and translational fidelity, we found that specific genes involved in host interactions, metabolism, and information processing are disproportionally deregulated in mRNA translation. This dysregulation is linked to a substantial reduction in translational capacity and fidelity in m6A2058 ribosomes. These findings point to a general "inefficient translation" mechanism of trade-offs associated with multidrug-resistant ribosomes.

    Abstract Rice is an important dietary source of the toxic mineral cadmium (Cd) for populations in which rice is the main staple food. When grown in agricultural soils that are contaminated with Cd, rice often accumulates excessive Cd into the grains, which is a serious threat to agricultural sustainability and human health. To limit Cd accumulation in rice grains, studies on the genetic basis of Cd accumulation in rice have been carried out extensively, and some low-Cd rice varieties have also been developed in recent years. However, the challenges in low-Cd rice breeding still exist because the outcomes of the current genetic improvements for low-Cd rice cannot fully meet the requirements for the development of Cd-safe rice at present. In this review, we outline the progress in understanding the physiological mechanisms and the genetic nature of Cd accumulation in rice and summarize the strategies and outcomes of low-Cd rice breeding over the past decade. By graphing the physiological mechanism of Cd transport in the rice plant, three key steps and some underlying genes are summarized and discussed. Also, two genetic features of the natural variation in rice grain-Cd accumulation, the phenotypic plasticity and subspecies divergence, and the potential genetic explanations for these features are also discussed. Finally, we summarize and discuss current progress and the potential issues in low-Cd rice breeding using different breeding strategies. We hope to propose strategies for future success in the breeding of low-Cd rice varieties over the next decade.

    Abstract Currently, nonalcoholic fatty liver disease (NAFLD) is the main cause of chronic liver disease and liver-related mortality worldwide. Hepatocellular carcinoma (HCC) is a fatal complication in patients with NAFLD. However, whether statins can reduce the risk of HCC in patients with NAFLD remains controversial. We aimed to determine the relationship between statin use and HCC occurrence among patients with NAFLD. We independently retrieved related studies from PubMed, EMBASE, Cochrane Library, Web of Science, and ClinicalTrial.gov (from 1 January 2000 to 27 February 2022). The main outcome was the development of HCC. A fixed-effects model was used to merge odds ratio (OR) in the meta-analysis. Five studies involving 684 363 patients were included. The results of the meta-analysis suggested a significantly lower risk of HCC among statin users with NAFLD [OR = 0.59; 95% confidence interval (CI), 0.39-0.89; I2 = 87.90%]. Additionally, a lower risk of HCC was observed among patients with NAFLD aged less than 65 years (OR = 0.59; 95% CI, 0.46-0.77; I2 = 20.50%). Statins can reduce the risk of HCC in patients aged less than 65 years with NAFLD.

    Abstract Introduction: Objectives: to determine the effects of vitamin B12 supplementation on neuropsychological function and disease progression in middle aged and elderly patients with cognitive impairment. Methods: this was a prospective case-control study. From May 2020 to May 2021, 307 participants clinically diagnosed with cognitive impairment in the Department of Neurology of the First Affiliated Hospital of Chongqing Medical University were enrolled. A total of 115 patients were included in this study. Meanwhile, 115 participants with cognitive impairment were randomly assigned in equal proportions to two groups: vitamin B12 treatment group (n = 58, vitamin B12 500 mg/d intramuscularly for seven days, followed by cobamamide 0.25 mg/d and methylcobalamin 0.50 mg/d) and the control group (n = 57). Demographic characteristics and blood biochemical variables were obtained from all participants. Cognitive performance was measured using the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA). Cognitive performance was measured at baseline and after six months. Results: the vitamin B12 supplementation treatment patients who presented with cognitive impairment showed significant improvement, especially in attention, calculation (p < 0.01) and visual-constructional ability (p < 0.05), in their neuropsychological function compared to their matched group. Conclusion: vitamin B12 supplementation may improve frontal function in patients with cognitive decline. Vitamin B12 levels should be investigated in all patients with cognitive impairment.

    Abstract Background: Fluorescence immunoassays are commonly employed for the detection of pathogenic bacteria as a means of ensuring food safety and preserving public health. However, the challenges such as poor photostability and background interference have limited their sensitivity and accuracy. The emergence of metal-organic frameworks (MOFs) as a label probe offers a promising solution for advancing fluorescence immunoassays owing to their tunable nature. Nonetheless, the low fluorescence efficiency of MOFs and the potential risk of dye leakage pose obstacles to achieving high detection sensitivity. Therefore, there exists a pressing need to fully utilize the potential of MOF composites in fluorescence immunoassays.
    Results: We explored the potential of glucose oxidase-encapsulated zeolitic imidazole framework-90 (GOx@ZIF-90) as a label probe to construct a time-resolved fluorescence immunoassay with amplified detection signal. This immunoassay involved functionalizing Fe
    Significance: This study not only presented a new method for detecting foodborne pathogens but also highlighted the potential of enzyme-encapsulated MOF composites as label probes in immunoassays, providing valuable insights for the design and fabrication of MOF composites for various applications.
