Objectives: This review endeavors to elucidate the complex interplay underlying diseases associated with ferroptosis and to delineate the multifaceted mechanisms by which triterpenoid and steroidal saponins modulate this form of cell death.
Methods: A meticulous examination of the literature was undertaken, drawing from an array of databases including Web of Science, PubMed, and Wiley Library, with a focus on the keywords "ferroptosis," "saponin," "cancer," "inflammation," "natural products," and "signaling pathways."
Key Findings: Ferroptosis represents a distinctive mode of cell death that holds considerable promise for the development of innovative therapeutic strategies targeting a wide range of diseases, especially cancer and inflammatory disorders.
Microorganisms, the major decomposers of plant residues, are crucial for soil nutrient cycling. Living grass mulching effectively alters microbial community structure and promotes nutrient cycling. However, its consistency with mulching ages and growth periods remains unclear.

It remains poorly investigated how to optimise temporary pacing in these patients. This study aimed to explore the potential reduction in the PPM implantation rate using temporary-permanent pacemaker (TPPM) as a 1-month bridge.

Soil phosphorus (P) availability is critical for productivity in tropical and subtropical forests. However, it was still poorly understood how soil P content and fraction respond to various forest management practices in these regions.

Materials And Methods: Data were collected retrospectively from 685 HCC patients undergoing percutaneous cryoablation at Tianjin Medical University Cancer Hospital between January 2018 and December 2021. Of these, 106 patients had lesions in high-risk sites, defined as a minimum distance of less than 10 mm from the heart/great vessels, diaphragm, gastrointestinal tract, and gallbladder, as determined by preoperative CT or MRI imaging.

Clarifying the accumulation pattern of soil microbial residue carbon and its contribution to soil organic carbon (SOC) across stand age is helpful to understand the mechanism underlying soil carbon cycling. In this study, we analyzed the differences of amino sugar content, physicochemical properties and microbial composition in surface soil (0-10 cm) in young (6 a), middle-aged (13 a), near-mature (29 a), mature (38 a) and over-mature (57 a) plantations of subtropical China, quantified the microbial residue carbon content and its contribution to SOC, and discussed the mechanism. The results showed that SOC, total nitrogen, amorphous iron oxide and leucine aminopeptidase contents in the middle-aged plantation were significantly lower than those in the mature plantation.

The patients received sintilimab (200 mg) plus IBI305 (7.5 mg/kg) and HAIC (FOLFOX for 23 h) and were treated every 3 weeks.

Methods: In this study, we utilized multi-center RNA sequencing and non-negative matrix factorization clustering (NMF) to identify a group of metabolism-related genes that could effectively predict the immune status and survival (both disease-free survival and overall survival) of pancreatic ductal adenocarcinoma (PDAC) patients. Subsequently, through the integration of single cell sequencing and our center's prospective and retrospective cohort studies, we identified ABHD17C, which possesses metabolic and immune-related characteristics, as a potential biomarker for predicting the prognosis and response to anti-PD1 therapy in PDAC.
Background: Molecular targeted therapy combined with immunotherapy significantly improves the prognosis of patients with advanced liver cancer. Additionally, hepatic arterial infusion chemotherapy (HAIC) can improve the prognosis of patients with advanced liver cancer. This real-world study aimed to evaluate the clinical efficacy and safety of HAIC combined with molecular targeted therapy and immunotherapy in the treatment of primary unresectable hepatocellular carcinoma (uHCC).

Pinus massoniana Lamb. Plantations are widely distributed in China and play a vital role in forest carbon sequestration.
View Article and Find Full Text PDFLiving grass mulching (LGM) is an important orchard floor management that has been applied worldwide. Although LGM can effectively enhance soil nutrient availability and fertility, its effects on microbial-mediated soil nutrient cycling and main drivers are unclear. Meanwhile, the variation of enzyme activities and soil nutrient availability with LGM duration have been rarely studied.

Morphological classification and corresponding TAVR strategies for AR are lacking yet.
Methods: The AURORA study is a prospective, multicenter, single-arm cohort study to evaluate the safety and efficacy of transfemoral TAVR for severe AR in patients with high or prohibitive risk for surgery.
Background: The incidence rate of lung large cell neuroendocrine carcinoma (LCNEC) in lung cancer is low, but the malignancy is high and the prognosis is poor. We used the Surveillance, Epidemiology, and End Results (SEER) database to determine the population distribution of organ metastasis in LCNEC, conduct survival analysis, judge prognostic factors, and provide direction for follow-up diagnosis and treatment.
Materials And Methods: By logging into the SEER database, the data of lung LCNEC were retrieved and the target population was selected.
In the context of rapid socio-economic development, eliciting "production-living-ecological" space (PLES) changes with corresponding ecosystem service benefits is critical for national land optimization and regional sustainability. Based on land use data obtained via remote sensing of 1980, 2000, 2018, and from a PLES perspective, we applied geo-information Tupu to depict land use transformations in the Three Gorges Reservoir Area (TGRA) from 1980 to 2018. The ecological/environmental effects of land use transformation were also explored based on the contribution value of ecosystem service.
View Article and Find Full Text PDFTumor-associated macrophages (TAMs), one of the most common cell components in the tumor microenvironment, have been reported as key contributors to cancer-related inflammation and enhanced metastatic progression of tumors. To explore the underlying mechanism of TAM-induced tumor progression, TAMs were isolated from colorectal cancer patients, and the functional interaction with colorectal cancer cells was analyzed. Our study found that coculture of TAMs contributed to a glycolytic state in colorectal cancer, which promoted the stem-like phenotypes and invasion of tumor cells.

The sibling rivalry between HIF-1α and HIF-2α in hypoxic tumor growth and progression still remains to be resolved, including in HCC. In this study, we aimed to analyze the mechanism by which HIF-1α and HIF-2α balance the proliferative response of HCC cells to hypoxia.
