Escherichia coli Nissle 1917 (EcN) is a unique probiotic utilized to treat inflammatory bowel disease and irritable bowel syndrome. Outer membrane vesicles (OMVs) from EcN can not only deliver pro-biotic anti-inflammatory molecules to cancer cells to exert anti-rectal cancer effects, but also deliver therapeutic drugs, genes, and other "cargoes" encapsulated in the vesicles to specific cells, making them an ideal vehicle for drug delivery. In this study, we successfully isolated OMVs of probiotic origin and obtained BCN-OMVs by encapsulating baicalin (BCN) in EcN-OMVs.

Purpose: Previous studies have shown higher cardiovascular mortality risk with higher monocyte-lymphocyte ratio levels in general population. However, the levels of oxidative stress in individuals with type 2 diabetes are higher than those in the general population, which may affect the link between monocyte-to-lymphocyte ratio and cardiovascular disease deaths. And the association between the monocyte-to-lymphocyte ratio and mortality risk in people with type 2 diabetes still be unknown.

Most affected patients do not exhibit obvious discomfort symptoms or imaging findings until OA progresses, leading to irreversible destruction of articular cartilage and bone. Therefore, developing new diagnostic biomarkers that can reflect articular cartilage injury is crucial for the early diagnosis of OA.

Developing innovative drug delivery systems is crucial to address these issues by modifying the adverse microenvironment and promoting effective wound healing. Herein, we designed a novel drug delivery platform using manganese dioxide nanoflower hybridized gold nanoparticle composites (MnO-Au) synthesized via a hydrothermal reaction, and investigated the potential of MnO-Au nanoflowers to relieve the high oxidative stress microenvironment and regulate diabetic wound tissue healing.

Methods: A retrospective analysis was conducted on 73 post-transplant renal patients who underwent ultrasound contrast examinations at Yiyang Central Hospital from July 2022 to December 2023, They were diagnosed clinically and pathologically. Based on pathological and clinical diagnostic results, the patients were divided into three groups: 47 cases in the stable renal function group, 18 cases in the acute rejection (AR) group, and 8 cases in the delayed graft function (DGF) group.
Because of the complex structure and inherent inert chemical activity of lignin, it is still challenging to depolymerize lignin to obtain valuable chemicals efficiently. Here, we present an FeCl-promoted photocatalytic depolymerization strategy to realize the C-C oxidative cleavage of lignin model compounds at room temperature. The method generates benzoic acid and phenol compounds in high yields.

This study was designed to evaluate the effects of embankment dams on natural forests dominated by and test whether the dam-shrub system is a preferable updated defense.
Methods: Coastal forests on two typical flats, one before and one behind embankment dams, were investigated using quadrats and lines.
Background: Internet exclusion and depressive symptoms are prevalent phenomena among older adults; however, the association between internet exclusion and depressive symptoms remains limited. This study aims to investigate the association between internet exclusion and depressive symptoms among older adults from high-income countries (HICs) and low- and middle-income countries (LMICs).
Methods: We conducted a comprehensive longitudinal, cross-cultural analysis, and the participants were adults aged 60 years and older from 32 countries participating in five nationally representative longitudinal cohort studies: the Health and Retirement Study (HRS), the English Longitudinal Study of Ageing (ELSA), the Survey of Health, Ageing and Retirement in Europe (SHARE), the China Health and Retirement Longitudinal Study (CHARLS), and the Mexican Health and Ageing Study (MHAS).
Background: Synthetic lethality (SL) emerges as a novel concept being explored to combat cancer progression and resistance to conventional therapy. Despite the efficacy of chemotherapy in select cases of colorectal cancer (CRC), a substantial proportion of patients encounter challenges, leading to an adverse prognosis of CRC patients. CRC-related SL genes offer a potential avenue for identifying therapeutic targets.

Quorum sensing (QS) is an intercellular communication mechanism that coordinates bacterial activities involved in various virulence mechanisms, such as acquiring host nutrients, facilitating biofilm formation, enhancing motility, secreting virulence factors, and evading host immune responses, all of which play a crucial role in the colonization and infection of . The LasI/R and RhlI/R sub-systems dominate in the QS system of .

The immunological mechanisms underlying chronic colitis are poorly understood. T follicular helper (T) cells are critical in helping B cells during germinal center reactions. In a T cell transfer colitis model, a lymphoid structure composed of mature dendritic cells (DCs) and T cells was found within T cell zones of colonic lymphoid follicles.

CD8 T cells are rendered exhausted in tumor and chronic infection. Among heterogeneous exhausted T cells, a subpopulation of progenitor-like (Tpex) cells have been found important for long-term tumor or pathogen control and are also the main responders in immunotherapy. Using an RFP reporter mouse for the orphan nuclear receptor NR4A1, originally characterized as critical in T cell dysfunction, we discover that the reporter is highly expressed in Tpex cells in tumor and chronic infection.

Climate change and human activities have intensified variations of water table depth (WTD) in wetlands around the world, which may strongly affect greenhouse gas emissions. Here, we analyzed how emissions of CO, CH, and NO from the Zoige wetland on the Qinghai-Tibetan Plateau (QTP) vary with the WTD. Our data indicate that the wetland shows net positive global warming potential (11.
