Vincristine exerts antiglioma effects by inhibiting the PI3K/AKT signaling pathway: A mechanistic study based on network pharmacology, bioinformatics analysis, and experimental validation.

In clinical settings, glioma patients often develop secondary resistance to first-line chemotherapy drugs. Vincristine has been reported for its application in cancer chemotherapy, but its molecular mechanism of action remains unclear. This study aimed to identify potential targets of vincristine in glioma using network pharmacology and to experimentally validate the possible molecular mechanisms against glioma.

Online registry of neonatal necrotising enterocolitis in Shenzhen: protocol for a multicentre, prospective, open, observational cohort study.

Introduction: Necrotising enterocolitis (NEC) of the intestine of preterm infants leads to the risk of abdominal surgery, short bowel syndrome, neurodevelopmental disorders and death. Although the risks of NEC and its complications have been recognised in many countries, few countries have established NEC-specific registries to continuously monitor its aetiology and prognosis. In China, the understanding of risk factors and prognosis of NEC is incomplete, characterised by a lack of evidence from prospective and multicentre studies.

KMT2A regulates the autophagy-GATA4 axis through METTL3-mediated mA modification of ATG4a to promote NPCs senescence and IVDD progression.

Intervertebral disc degeneration (IVDD), a disease associated with ageing, is characterised by a notable increase in senescent nucleus pulposus cells (NPCs) as IVDD progresses. However, the specific mechanisms that regulate the senescence of NPCs remain unknown. In this study, we observed impaired autophagy in IVDD-NPCs, which contributed to the upregulation of NPCs senescence and the senescence-associated secretory phenotype (SASP).

Inhibition of cathepsin L ameliorates inflammation through the A20/NF-κB pathway in endotoxin-induced acute lung injury.

Acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) is a severe inflammatory condition that remains refractory; however, its molecular mechanisms are largely unknown. Previous studies have shown numerous compounds containing 4-indolyl-2-aminopyrimidine that display strong anti-inflammatory properties. In our research, we identified that a 4-Indole-2-Arylaminopyrimidine derivative named "IAAP" suppressed lipopolysaccharide (LPS)-induced inflammation.

Combining high-resolution CT parameters and inflammatory markers to predict spread through air spaces in lung cancer.

Objective: To explore the predictive value of high-resolution computed tomography (CT) parameters and inflammatory markers for spread through air spaces (STAS) in lung cancer patients.

Methods: A retrospective analysis was conducted on 72 lung cancer patients with STAS and 128 STAS-negative patients treated during the same period. Differences in high-resolution CT indicators and inflammatory markers between the two groups were assessed.

Experimental study on negative skin friction characteristics of double-sleeve pile.

Pile foundation structures are widely used in the construction of high-piled wharves in coastal soft soil areas due to their excellent adaptability to such environments. However, the extensive, deep backfilling involved in constructing these wharves can easily induce negative skin friction (NSF) on the piles, resulting in safety issues such as excessive settlement during the service life of the structures. This paper presents an indoor model experiment to examine the distribution of the THE NSF under varying pile-top loads and surcharge effects on single pile and double-sleeve pile foundations.

Silencing AREG Enhances Sensitivity to Irradiation by Suppressing the PI3K/AKT Signaling Pathway in Colorectal Cancer Cells.

Background: It has been established that Spalt-Like Transcription Factor 4 (SALL4) promotes Colorectal Cancer (CRC) cell proliferation. Furthermore, Amphiregulin (AREG) is crucially involved in cancer cell proliferation and therapeutic resistance regulation. In this regard, this study aimed to establish whether SALL4 affects the radiosensitization of CRC cells via AREG expression regulation.

Transcriptome and Metabolome Based Mechanisms Revealing the Accumulation and Transformation of Sugars and Fats in Seed Kernels during the Harvesting Period.

seed kernel is a nutrient-rich and widely consumed nut whose yield and quality are affected by, among other things, harvesting time and climatic conditions, which reduce economic benefits. To investigate the optimal harvesting period of seed kernels, this study determined the nutrient composition and seed kernel morphology and analyzed the gene expression and metabolic differences of seed kernels during the harvesting period by transcriptomics and metabolomics. The results revealed that during the maturation of seed kernels, there was a significant increase in the width, thickness, and weight of the seed kernels, as well as a significant accumulation of sucrose, soluble sugars, proteins, starch, flavonoids, and polyphenols and a significant decrease in lipid content.

Controlling size and distribution of Au nano-particles on C3N4 for high-efficiency photocatalytic hydrogen production.

With advantages such as low cost, high stability, and ease of production, visible light photocatalytic C3N4 with a unique microscopic layered structure holds significant potential for development. However, its hydrogen production efficiency remains low due to the pronounced recombination of photo-generated charge carriers and limited surface reaction sites. Normally, the photocatalytic performance of C3N4 can be enhanced by loading noble metals with surface plasmon resonance.

TGF-β signaling promotes eosinophil activation in inflammatory responses.

Eosinophils, traditionally associated with allergic phenomena, play a pivotal role in inflammatory responses. Despite accumulating evidence suggesting their pro-inflammatory function upon activation, the underlying mechanisms governing eosinophil activation remain incompletely characterized. In this study, we investigate the local activation of pulmonary and colon eosinophils within the inflammatory microenvironment.

Effect of biochar and iron ore tailing waste amendments on cadmium bioavailability in a soil and peanut seedling system.

Biochar and iron ore tailing waste have been widely separately applied for remediation of various contaminants, but the remediation effect of their combination on cadmium (Cd) pollution is unclear. In this study, the peanut biochar (BC), thermally activated iron ore tailing waste (TS), and the products of the co-pyrolysis of peanut shell and iron ore tailing waste (TSBC) were prepared for stabilizing Cd and reducing its bio-accessibility in soil and peanut seedling system. Present amendments enhanced soil pH, cation exchange capacity, electrical conductivity, and organic carbon content.

Towards advanced removal of organics in persulfate solution by heterogeneous iron-based catalyst: A review.

Heterogeneous iron-based catalysts have drawn increasing attention in the advanced oxidation of persulfates due to their abundance in nature, the lack of secondary pollution to the environment, and their low cost over the last a few years. In this paper, the latest progress in the research on the activation of persulfate by heterogeneous iron-based catalysts is reviewed from two aspects, in terms of synthesized catalysts (Fe, FeO, FeO, FeOOH) and natural iron ore catalysts (pyrite, magnetite, hematite, siderite, goethite, ferrohydrite, ilmenite and lepidocrocite) focusing on efforts made to improve the performance of catalysts. The advantages and disadvantages of the synthesized catalysts and natural iron ore were summarized.
