Article Synopsis
  • Deep nitrate accumulation has been found below 1 meter in various soil regions, but there is a lack of documentation in the black soil areas of northeast China, specifically Phaeozems and Chernozems.
  • A study analyzed nitrate levels and soil properties down to 10 meters in three locations (Fujin, Hailun, and Lindian), revealing that Lindian had the highest nitrate concentration, especially at 3 meters.
  • The findings suggest that nitrate makes up a significant portion of the nitrogen stock in Lindian, and the soil's characteristics, like clay and pH, are important for understanding nitrate distribution, which is relevant for sustainable soil management and groundwater pollution prevention.

Objective: Clinical practice guidelines (CPGs) for Integrated Traditional Chinese and Western Medicine (TCM and WM) are important medical documents used to assist medical decision-making and are of great significance for standardizing clinical pathways. However, due to the constraints of text format, it is difficult for Integrated TCM and WM CPGs to play a real role in medical practice. In addition, how to standardize the structure and semantic relationships between Integrated TCM and WM CPG knowledge, and realize the construction of computable, sharable and reliable CPGs, remains an urgent issue to be addressed.

  • Combined pollution from cadmium (Cd) and arsenic (As) poses risks to crop safety and human health, particularly in rice cultivation.
  • A study investigated the effects of a silicon-rich amendment (HA) made from rice husk on reducing the uptake of Cd and As in rice seedlings, showing that it enhanced growth and decreased metal concentrations in the plants.
  • Findings indicated that HA improved iron plaque composition in rice, leading to lower Cd absorption and higher As retention, making HA a promising eco-friendly solution for remediating contaminated paddy fields.

The main pathogenic features of immunoglobulin A vasculitis (IgAV) are overactive B cells and elevated production of IgA, which requires help from T follicular helper 17 (Tfh17) cells. To evaluate the pathological role of Tfh17 cells in IgAV, we investigated the mechanism responsible for Tfh17 differentiation and explored how to ameliorate IgAV by modulating Tfh17 generation. Peripheral blood mononuclear cells from IgAV patients were analyzed by flow cytometry.

TIMM9 has been identified as a mediator of essential functions in mitochondria, but its association with pan-cancer is poorly understood. We herein employed bioinformatics, computational chemistry techniques and experiments to investigate the role of TIMM9 in pan-cancer. Our analysis revealed that overexpression of TIMM9 was significantly associated with tumorigenesis, pathological stage progression, and metastasis.

Background: Hepatitis B poses a significant global public health challenge, with mother-to-child transmission (MTCT) being the primary method of hepatitis B virus (HBV) transmission. The prevalence of HBV infection in China is the highest in Asia, and it carries the greatest burden globally.

Objective: This study aims to critically evaluate the existing local strategies for preventing MTCT and the proposed potential enhancements by analyzing the prevalence of hepatitis B among pregnant women and their neonates in Yinchuan.

The widespread adoption of wireless communication technology, especially with the introduction of artificial intelligence and the Internet of Things, has greatly improved our quality of life. However, this progress has led to increased electromagnetic (EM) interference and pollution issues. The development of advanced microwave absorbing materials (MAMs) is one of the most feasible solutions to solve these problems, and has therefore received widespread attention.

Background: "The hidden costs of informal caregiving" is an interdisciplinary concept. While caregivers make a significant contribution to the process of caregiving, they sacrifice their leisure time, and incur risks of dropping out of the job, impaired mental and physical health, and decreased well-being within the context of caregiving. Those invisible sacrifices are often overlooked and described as hidden costs of informal caregiving.

  • Fuchs endothelial corneal dystrophy (FECD) leads to corneal endothelial degeneration and impaired vision due to the accumulation of guttae on Descemet's membrane.
  • Researchers established a FECD mouse model using UVA exposure and utilized various staining techniques, including aniline blue (AB) and Masson's trichrome, to analyze corneal structures.
  • AB staining proved to be a quick and effective method for identifying guttae areas in the corneas of FECD mice, showing significant correlation with collagen I presence in the affected regions.

Magnetic resonance vessel wall imaging (MR-VWI) is an emerging imaging technology used to assess the progressive risk of unruptured intracranial aneurysms (UIAs). Unlike the standard evaluation model, MR-VWI is still debatable. This study aims to further define the potential relationship between aneurysm wall enhancement (AWE) and aneurysm stability.

Article Synopsis
  • - Triple-negative breast cancer (TNBC) is a highly lethal subtype of breast cancer, and the study focuses on how extracellular vesicles (EVs) derived from TNBC tumors promote tumor growth by influencing macrophage polarization towards an M2 phenotype.
  • - The research discovered that the long non-coding RNA (lncRNA) MALAT1 is packaged in TNBC-derived EVs and, upon being transferred to macrophages, enhances M2 polarization, which is linked to worse patient prognosis.
  • - The findings suggest that MALAT1 activates the Hippo/YAP signaling pathway through the upregulation of POSTN, thereby facilitating both the onset and spread of TNBC, indicating potential therapeutic targets for intervention.

Chitosan-based biomass packaging materials are a promising material for food preservation, but their limited solubility, antioxidant capacity, UV resistance, and mechanical properties severely restrict their application. In this study, we developed a novel chitosan-based coating/packaging composite (QCTO) using quaternary ammonium salt and tannic acid (TA)-modified chitosan (QCS-TA) and oxidized chitosan (OCS). The introduction of quaternary ammonium salt and TA effectively improves the water solubility and antibacterial, antioxidant, and UV-resistant properties of chitosan.

Alzheimer's disease is associated both with imbalances in Al production and changes in viscosity in cells. Their simultaneous measurement could therefore provide valuable insights into Alzheimer's disease pathology. Their simultaneous measurement would therefore be of great value in investigating the pathological mechanism of Alzheimer's disease.

Active road noise control (ARNC) systems have been widely investigated for low-frequency road noise attenuation in vehicle cabins. Multiple reference and error sensors are usually required to ensure noticeable noise reduction. However, this tends to slow down the convergence speed of adaptive algorithms due to the coupling of secondary paths and the cross correlation of reference signals.
