Driving mechanism of urban expansion in the Bohai Rim urban agglomeration from the perspective of spatiotemporal dynamic analysis.

The urban agglomeration represents the predominant form of new urbanisation, yet the evolution of its internal spatial structure exhibits pronounced spatial and temporal heterogeneity. This study concentrates on the Bohai Rim urban agglomeration, one of three major urban agglomerations in China, which has received comparatively limited research attention but has also undergone substantial urbanisation. Therefore, we reassessed and explored the spatial-temporal evolution of the spatial structure of urban expansion using Exploratory Spatiotemporal Data Analysis (ESTDA), and summarized the driving mechanisms using Geographically and Temporally Weighted Regression (GTWR).

Blocking GP130 binding in interleukin-11 through site-specific PEGylation attenuates bleomycin-induced pulmonary fibrosis in mice.

Recent insights have identified interleukin-11 (IL-11) as a pivotal profibrotic cytokine, with its signaling through IL-11Rα and GP130 receptors emerging as a promising therapeutic target for fibrotic diseases. Herein, we developed receptor-biased IL-11 via site-specific PEGylation at the GP130 binding interface, aiming to explore its therapeutic potential for bleomycin-induced pulmonary fibrosis in mice. By conducting single site-directed cysteine mutagenesis at site II or site III of IL-11, we refined the conjugation site, demonstrating that mutation at site III exhibits heightened sensitivity to GP130 binding and signaling.

Site-specific dimerization of interleukin-11 alleviates bleomycin-induced pulmonary fibrosis in mice.

Interleukin-11 (IL-11) has recently been identified as a critical profibrotic cytokine, and IL-11 signaling pathway via IL-11Rα and GP130 receptors has been shown to be a promising therapeutic target for the treatment of fibrotic diseases. Herein, we devised two kinds of IL-11 dimer with receptor-biased binding ability through site-specific crosslinking at the interface involving GP130 binding and signaling, aiming to explore their therapeutic potentials for bleomycin-induced pulmonary fibrosis in mice. A single cysteine mutation at site W147 of human IL-11 (IL-11 W147C) was conducted for site-specific crosslinking.

Dose-dependent effects of transcranial photobiomodulation on brain temperature in patients with major depressive disorder: a spectroscopy study.

This study aimed to evaluate the dose-dependent brain temperature effects of transcranial photobiomodulation (t-PBM). Thirty adult subjects with major depressive disorder were randomized to three t-PBM sessions with different doses (low: 50 mW/cm, medium: 300 mW/cm, high: 850 mW/cm) and a sham treatment. The low and medium doses were administered in continuous wave mode, while the high dose was administered in pulsed wave mode.

The legacy effect of long-term nitrogen fertilization on nitrous oxide emissions.

The primary driver of increasing atmospheric concentrations of nitrous oxide (NO) is the use of organic and synthetic fertilizer to increase agricultural crop production. Current global estimates are based on IPCC NO emission factor (EF) calculations, although there are shortcomings as many of the NO EFs are derived from measurements during the cropping season. These neglect the fallow season, and do not adequately account for double or even triple cropping systems or legacy effects on soil NO emissions in the following year.

Protocol for preparing metabolically reprogrammed human CAR T cells and evaluating their in vitro effects.

Chimeric antigen receptor (CAR) T cell therapy represents a cutting-edge cancer treatment, making the development and testing of CAR T cells crucial for advancing this therapeutic strategy. We present a protocol for creating and characterizing human epidermal growth factor receptor 2 (HER2)- and glypican-3 (GPC3)-metabolic reprogramming (MR)-CAR T cells by overexpressing adenosine deaminase 1 (ADA1) and CD26 (also known as dipeptidylpeptidase-4 or DPP4). This approach effectively converts immunosuppressive adenosine into inosine, which supports T cell survival in glucose-deficient tumor microenvironments.

Exploring the distribution and habitat preferences of Polytrichaceae (Bryophyta) in Tibet, China.

The Qinghai-Tibet Plateau stands as one of the most ecologically fragile and biodiversity-rich regions globally. Understanding the distribution of different taxa and their relationship with environmental factors is crucial for effective conservation and sustainable management. Polytrichaceae, a significant bryophyte family widely distributed in Tibet, displays distinct structural, morphological, and phylogenetic traits compared to other mosses.

prescription for preventing and treating postoperative recurrence and metastasis of gastric cancer: a randomized controlled trial protocol.

Introduction: Postoperative recurrence and metastasis of gastric cancer (GC) are primary factors that contribute to poor prognosis. GC recurs at a rate of approximately 70%-80% within 2 years after local treatment and approximately 90% within 5 years. "" is the core pathogenesis of GC recurrence and metastasis.

Soluble expression of recombinant human interleukin-2 in Escherichia coli and its facile production.

Recombinant human interleukin-2 (rhIL-2) represents one of the most difficult-to-produce cytokines in E. coli due to its extreme hydrophobicity and high tendency to formation of inclusion bodies. Refolding of rhIL-2 inclusion bodies always represents cumbersome downstream processes and low production efficiency.

Selective refueling of CAR T cells using ADA1 and CD26 boosts antitumor immunity.

Chimeric antigen receptor (CAR) T cell therapy is hindered in solid tumor treatment due to the immunosuppressive tumor microenvironment and suboptimal T cell persistence. Current strategies do not address nutrient competition in the microenvironment. Hence, we present a metabolic refueling approach using inosine as an alternative fuel.

Partial substitution of manure increases NO emissions in the alkaline soil but not acidic soils.

The fertilization regimes of combining manure with synthetic fertilizer are benefits for crop yields and soil fertility in cropping systems as compared to sole synthetic fertilization, but the responses of nitrous oxide (NO) emissions to these practices are inconsistent in the literatures. We hypothesized that it is caused by different proportions of nitrogen (N) applied as manure and various soil properties. Here, we conducted a microcosm experiment, and measured the NO emissions from control (no N) and five manure substitution treatments (supplied 100 mg N kg using the combination of urea with manure) with a range of proportions of N applied as manure (0, 25%, 50%, 75%, and 100%) in three different soil types (fluvo-aquic soil, black soil, and latosol) under aerobic condition.

RTCB deficiency triggers colitis in mice by influencing the NF-κB and Wnt/β-catenin signaling pathways.

RNA terminal phosphorylase B (RTCB) has been shown to play a significant role in multiple physiological processes. However, the specific role of RTCB in the mouse colon remains unclear. In this study, we employ a conditional knockout mouse model to investigate the effects of RTCB depletion on the colon and the potential molecular mechanisms.

Study on the mechanism of MDSC-platelets and their role in the breast cancer microenvironment.

Myeloid-derived suppressor cells (MDSCs) are key immunosuppressive cells in the tumor microenvironment (TME) that play critical roles in promoting tumor growth and metastasis. Tumor-associated platelets (TAPs) help cancer cells evade the immune system and promote metastasis. In this paper, we describe the interaction between MDSCs and TAPs, including their generation, secretion, activation, and recruitment, as well as the effects of MDSCs and platelets on the generation and changes in the immune, metabolic, and angiogenic breast cancer (BC) microenvironments.

Digestate induces significantly higher NO emission compared to urea under different soil properties and moisture.

Digestate is considered as an option for recycling resources and a part of the substitution for chemical fertilizers to reduce environmental impacts. However, its application may lead to significant nitrous oxide (NO) emissions because of its high concentration of ammonium and degradable carbon. The research objectives are to evaluate how NO emissions respond to digestate as compared to urea application and whether this depends on soil properties and moisture.

Traditional Chinese medicine is an important part of complementary alternative medicine. Jiedu Qingjin formula (JDQJF) is an effective national invention patent for the treatment of non-small cell lung cancer (NSCLC). We investigated the molecular biological mechanisms based on network pharmacology, molecular docking, and molecular dynamics simulations.

Nitrite stimulates HONO and NO but not NO emissions in Chinese agricultural soils during nitrification.

The long-lived greenhouse gas nitrous oxide (NO) and short-lived reactive nitrogen (N) gases such as ammonia (NH), nitrous acid (HONO), and nitrogen oxides (NO) are produced and emitted from fertilized soils and play a critical role for climate warming and air quality. However, only few studies have quantified the production and emission potentials for long- and short-lived gaseous nitrogen (N) species simultaneously in agricultural soils. To link the gaseous N species to intermediate N compounds [ammonium (NH), hydroxylamine (NHOH), and nitrite (NO)] and estimate their temperature change potential, ex-situ dry-out experiments were conducted with three Chinese agricultural soils.

Delineating the Role of Toll-Like Receptors in Inflammatory Bowel Disease.

Toll-like receptors (TLRs) recognize altered gut microbiota triggering an immune response. These responses play a critical role in the pathogenesis and treatment of inflammatory bowel disease (IBD). IBD is characterized by inflammation of the intestinal tracts as in Crohn's disease and ulcerative colitis.

Metagenomic and network analyses reveal key players in nitrification in upland agricultural soils.

Nitrification, a key step in soil nitrogen cycling, is a biologically mediated process crucial to the ecological environment. However, how nitrifiers drive nitrification under different soil properties and climatic factors at large spatial scales is poorly understood. Here, using metagenomic sequencing and network-based approaches, we identified key nitrifying species of upland agricultural soils in northern China, which spans a wide range of climates and geographic distances.

Soil pore structure mediates the effects of soil oxygen on the dynamics of greenhouse gases during wetting-drying phases.

The timing and magnitude of greenhouse gas (GHG) production depend strongly on soil oxygen (O) availability, and the soil pore geometry characteristics largely regulate O and moisture conditions relating to GHG biochemical processes. However, the interactions between O dynamics and the concentration and flux of GHGs during the soil moisture transitions under various soil pore conditions have not yet been clarified. In this study, a soil-column experiment was conducted under wetting-drying phases using three pore-structure treatments, FINE, MEDIUM, and COARSE, with 0 %, 30 %, and 50 % coarse quartz sand applied to soil, respectively.
