Twenty-seven dimeric lindenane sesquiterpenoid (LS) derivatives, including thirteen new hetero- or homo-dimers (1-13), were discovered from rare Chloranthaceae plant Chloranthus holostegius var. shimianensis. Their structures were elucidated by a combination of HRMS, spectroscopic analysis, single-crystal X-ray diffraction and CD exciton chirality method.

However, protein detection in clinical samples using solid-state nanopores remains challenging due to their heterogeneously charged spherical structure, which results in signals with extremely low signal-to-noise ratios (SNR) and low capture rates that are difficult to analyze. In this study, we employed a double-antibody sandwich technique to specifically capture and amplify the target antigen, which significantly improves the SNR and effectively distinguishes the target signal from background interference.

Introduction: Heat exposure and heatwaves are becoming more frequent and prolonged due to global warming. Heat exposure poses a significant potential risk for respiratory diseases. However, a comprehensive synthesis of existing evidence on the health impacts of heat exposure on respiratory diseases is lacking.
View Article and Find Full Text PDFPhages have garnered increasing attention due to their potential roles in biogeochemical cycling. However, their impacts on nitrogen cycling have primarily been inferred from the presence of putative auxiliary metabolic genes (AMGs) and the virus-host linkage, despite of very limited direct experimental evidence. In this study, a series of microcosms were established with the inoculation of either native or non-native phages to simulate coastal wetlands with different phage sources and different levels of copper (Cu) contamination.

Additionally, the study explored the potential of tRF-Pro-CGG as a diagnostic biomarker and therapeutic target in PC.
Methods: The expression levels of tRF-Pro-CGG in PC tissues and cell lines were analyzed using next-generation sequencing and quantitative real-time PCR (qRT-PCR).
Background: To investigate whether leukocyte telomere length (LTL) causally influences renal cell carcinoma (RCC) risk, this study applied Mendelian randomization (MR) analysis. Prior research examining LTL as a potential biomarker for RCC risk has yielded inconsistent findings.
Methods: We obtained summary-level LTL data from the UK Biobank genome-wide association study (n = 472,174) and gathered RCC data from both the FinnGen Consortium (n = 289,360) and the International Agency for Research on Cancer (IARC) (n = 13,230).
The current study explores the relationship between genetically predicted gut metabolites and functional outcomes following ischemic stroke, utilizing the Mendelian Randomization (MR) framework. Genetic information regarding gut microbiota-derived metabolites was sourced from 2076 participants of European descent participating in the Framingham Heart Study. Data on functional outcomes 90 days post-ischemic stroke were acquired from the Genetics of Ischemic Stroke Functional Outcomes Network (n = 6,021).

Approach And Results: Adult patients (≥ 18 years) who had received camrelizumab as part of AEC treatment were pooled from three independent, prospective observational cohort studies (NCT04616040, ChiCTR1900027275, and ChiCTR2000039499). The main outcomes were patterns of camrelizumab use, progression-free survival (PFS), overall survival (OS), and safety in the overall population and specific subgroups of underrepresented patients.
Olfactomedin 4 (OLFM4) is a member of the olfactomedin domain-containing olfactomedin glycoprotein family and plays important roles in innate immunity, inflammation, and cancer. It exhibits increased expression in gastric cancer patient tissues and has been shown to regulate proliferation and apoptosis in gastric cancer cells. However, the molecular mechanism(s) underlying OLFM4's role in gastric cancer remain unknown.

Among its polymorphs, β-Ga₂O₃ stands out due to the availability of high-quality, large-area single-crystalline substrates, particularly on the (100) surface, grown via melt-based bulk crystal growth. However, the low surface energy of β-Ga₂O₃ (100), akin to 2D materials, presents challenges in homoepitaxy, including poor nucleation and twin formation, which hinder its practical application.

Bovine herpesvirus 1 (BoHV-1) productive infection stimulates β-catenin-dependent transcription to facilitate virus replication. Phosphoglycerate kinase 1 (PGK1), which catalyses the initial step of ATP production during glycolysis, also has a mitochondrial form that is implicated in tissue injury across various diseases. However, the relationship between BoHV-1 replication and the PGK1 signalling pathway is not yet fully understood.
