Background: In patients with resectable non-small cell lung cancer (NSCLC), immune checkpoint inhibitor (ICI)-based regimens in both neoadjuvant and perioperative settings have demonstrated a survival benefit. However, no previous study has compared the efficacy between pure neoadjuvant and perioperative approaches, especially in patients who achieve a substantial pathologic response.

Methods: In this retrospective study, patients with clinical stage II-IIIB NSCLC who achieved either a major pathologic response (MPR) or pathologic complete response (pCR) after induction ICI plus chemotherapy, followed by resection, between 2019 and 2023 were identified from multicenter databases.

Article Synopsis
  • - The study investigates the role of fungi in degrading dimethylsulfoniopropionate (DMSP) and producing dimethylsulfide (DMS), a volatile gas relevant to climate change.
  • - Researchers found that specific fungi from deep coal-bearing sediments, like Aspergillus spp. and others, can effectively degrade DMSP and release DMS, highlighting a previously unrecognized function of these organisms.
  • - A particular fungus, Aspergillus sydowii, was identified as having the highest rate of DMS production and contained unique DMSP lyase genes (dddP and dddW), with dddW being a gene typically associated with bacteria, showcasing fungal diversity in DMSP metabolism

Fungi represent the dominant eukaryotic group of organisms in anoxic marine sedimentary ecosystems, ranging from a few centimeters to ~ 2.5 km below seafloor. However, little is known about how fungi can colonize anaerobic subseafloor environments for tens of millions of years and whether they play a role in elemental biogeochemical cycles.

Phthalic acid esters (PAEs) are ubiquitous environmental pollutants and are recognized as a threat to the environment and agricultural product safety across the world. In order to investigate the level of PAEs in garlic, soils, and agricultural films from Pizhou City, Jiangsu province, China, 11 garlic samples, 106 soil samples, and 4 agricultural film samples were collected and analyzed using GC-MS. In addition, the uptake and transport characteristics of six PAEs compounds classified as priority pollutants by the United States Environmental Protection Agency (EPA) in the garlic cultivar Daqingke were investigated under hydroponic conditions.

Article Synopsis
  • - The study investigates the roles of Alpha-L-fucosidase-1 (FUCA1) and matrix metalloproteinase 9 (MMP-9) in esophageal squamous cell carcinoma (ESCC), as previous research highlighted their opposing effects in various cancer types but not specifically in ESCC.
  • - Analysis of 90 ESCC patients showed high expressions of FUCA1 and MMP-9 were significantly associated with advanced disease stages and lymphatic invasion, suggesting a link between FUCA1 levels and worse prognostic factors.
  • - Univariate and multivariate analyses indicated that high FUCA1 and MMP-9 expressions independently predicted shorter overall survival, marking these proteins as potential prognostic markers in ES

  • * The insecticide demonstrated specific lethal doses (LD) and lethal concentrations (LC) for three rice planthopper species, revealing it to be effective in both adult and nymph stages.
  • * Monitoring from 2015-2019 shows N. lugens populations remained susceptible to triflumezopyrim, with no cross-resistance to other neonicotinoids, although artificial selection indicated a potential for resistance development over generations.

Background: In this study, we aimed to assess the clinical utility of detection of plasma microRNAs (miRNAs) in the diagnosis of pulmonary nodules.

Methods: Fifty-seven patients with pulmonary nodules who had undergone surgery were enrolled in our study from July 2016 to July 2017 at Sun Yat-sen University Cancer Center. We measured the expression levels of 12 miRNAs (miRNA-17, -146a, -200b, -182, -155, -221, -205, -126, -7, -21, -145, and miRNA-210) in plasma samples of 57 patients, including 15 benign pulmonary nodules patients and 42 malignant pulmonary nodules patients.

Article Synopsis
  • Aberrant expression of PD-L1 and P53 has been linked to cancer, and this study investigates their correlation with prognosis in patients with resected pulmonary lymphoepithelioma-like carcinoma (LELC).
  • The study analyzed data from 67 patients, finding that positive expressions of PD-L1 in tumor cells and P53 were associated with longer disease-free survival, especially in early-stage LELC, but not with overall survival.
  • The research suggests that PD-L1 and P53 could serve as potential therapeutic targets and recommends routine detection of these markers to help predict patient outcomes and responses to adjuvant therapy.

  • Rifampicin resistance mutations in the RNA polymerase β subunit gene cause diverse effects on bacterial metabolism and physiology, but the specific impacts of these mutations were not well understood before this study.
  • Researchers identified seven Rif mutations in the endophytic strain CC09, including six single point mutations and one double point mutation, and discovered varying effects on spore germination and antibiotic production.
  • The study indicates that these Rif mutations are not only useful for understanding transcription regulation but may also enhance the production of beneficial metabolites in bacteria.

To evaluate the effect of biochar amendment on the bioavailability of chlorantraniliprole (CAP) in soils with different physico-chemical properties, the uptake of CAP from various soils by earthworms was studied. It was observed that the biochar amendment of the soils affected the sorption of CAP, but the magnitude of the sorption enhancement by biochar amendment among the soils was varied, presumably due to the attenuation of the sorptivity of the biochar when amended in the soil. The amendment with biochars leads to a decrease in the bioavailability of CAP in the soils to earthworms, and more prominent for biochar BC850 amendment.

Pyrolysis of vegetative biomass into biochar and application of the more stable form of carbon to soil have been shown to be effective in reducing the emission of greenhouse gases, improving soil fertility, and sequestering soil contaminants. However, there is still lack of information about the impact of biochar amendment in agricultural soils on the sorption and environmental fate of pesticides. In this study, we investigated the sorption and dissipation of a neonicotinoid insecticide acetamiprid in three typical Chinese agricultural soils, which were amended by a red gum wood (Eucalyptus spp.
