Regulatory effects of luteolin on apoptosis and autophagy in lung cancer A549 cells
ABSTRACT Lung cancer is a common cause of cancer-related mortality worldwide. Luteolin, a naturally occurring flavonoid compound, was reported to exert anticancer effects through various mechanisms: A549 cell non-small cell lung cancer (NSCLC) serves as a model system. The objective of this study was to investigate the effects of luteolin on apoptosis and autophagy using A549 cells.

WTAP stabilized by USP7 contributes to enzalutamide resistance in prostate cancer via mediating AKT m 6 A-modification
Abstract Castration-resistant prostate cancer (CRPC) is one of the most prevalent cancers in men. The new generation androgen receptor (AR) inhibitor enzalutamide can improve the therapeutic effectiveness of patients with CRPC. However, these patients eventually develop acquired enzalutamide resistance (ENZR), and the mechanisms underlying resistance are not well understood.

Citywide community-based colorectal cancer screening in urban Shanghai: age and sex variations in risk mitigation from 1973 to 2020
Introduction Colorectal cancer (CRC) is one of the most diagnosed cancer worldwide, imposing a substantial disease burden on public health due to its high incidence. According to the latest estimates from GLOBOCAN 2022, there were nearly 2 million new cases and 1 million deaths of CRC in 2022, corresponding to the 3rd in incidence spectrum of malignancies and the 2nd in mortality spectrum, respectively (1).

Cardiac fibroblast heterogeneity in cardiac fibrosis implication for cell-type-specific treatment
Abstract Cardiac fibrosis is a central feature of heart disease, driven by excessive extracellular matrix (ECM) accumulation and associated with mechanical stiffening, electrical instability, and heart failure. While cardiac fibroblasts (CFs) were historically viewed as a uniform ECM-producing population, lineage tracing and single-cell/spatial transcriptomics reveal substantial fibroblast heterogeneity in healthy myocardium and distinct activation trajectories in disease.
Performance comparison of quantitative and qualitative fecal immunochemical tests in community-based colorectal cancer screening
Abbreviations CIR (cecal incubation rate) CRC (colorectal cancer) DR (detection rate) FIT (fecal immunochemical test) gFOBT (guaiac-based fecal occult blood test) NNS (number needed to scope) PPV (positive predictive value) qlFIT (qualitative fecal immunochemical test) qnFIT (quantitative fecal immunochemical test) Introduction According to the International Agency for Research on Cancer, colorectal cancer (CRC) has been the third most-commonly diagnosed cancer and the second-leading...
Wavelength-tuned transformation of the topological charge of a plasmonic vortex excited by linearly polarized light
Plasmonic vortex lenses (PVLs) have been developed to simplify the excitation conditions of surface plasmon polariton (SPP) vortex fields, transitioning from vector light with orbital angular momentum or circularly polarized light with spin angular momentum to linearly polarized (LP) light. However, these structures are typically designed for specific wavelengths.
Visualizing Back Electron Transfer in Eosin Y Photoredox Catalysis
Visualizing Back Electron Transfer in Eosin Y Photoredox Catalysis Back electron transfer (BET) in eosin Y (EY) photoredox catalysis was visualized via the fluorescence of single EYs. Commonly used quenchers, alkyl bromides and tertiary amine, were studied. BET was observed in alkyl bromides, but not in tertiary amine. The finding helped explain the mechanism of EY-catalyzed polymerization. This article is Open Access This article has not yet been cited.

The Impact of Special Character Areas on Property Values and Homeowners’ Experiences: Cases from Auckland, New Zealand
5. The Impact of Special Character Areas on Property Values and Homeowners’ Experiences An examination of capital values (CV) was completed, as presented in Table 1. The table shows the median and mean differences between capital values inside the SCAs and the surrounding areas, as well as the standard deviation. The highest median capital value was identified in designated SCA properties in Freemans Bay, at NZD 1,850,000.
Predictors of pacemaker implantation within three months after catheter ablation of atrial fibrillation
Abstract Background It is inevitable for patients to have a temporary or permanent pacemaker implanted during or after radiofrequency catheter ablation (RFCA) for treatment of atrial fibrillation (AF) in some cases. The aim of our study was to evaluate the incidence of pacemaker implantation (PMI) during or within 3 months of RFCA for AF and to identify the risk factors that were associated with PMI.

Details of the SBCSS have been described elsewhere.25 Briefly, the SBCSS is a longitudinal, population-based study of 5042 women, aged 20 to 75 years, who were diagnosed with primary breast cancer between March 2002 and April 2006.
An interference screw made by silk fibroin-based bulk material with high content of hydroxyapatite for anterior cruciate ligament reconstruction in a rabbit model
An interference screw made by silk fibroin-based bulk material with high content of hydroxyapatite for anterior cruciate ligament reconstruction in a rabbit model Upgradation is still in need for the clinical-applied interference screws in anterior cruciate ligament reconstruction for more reliable fixation. Silk fibroin bulk materials offer a promising opportunity for this application except lacking osteoinductivity to some extent.
Degradable Holey Palladium Nanosheets with Highly Active 1D Nanoholes for Synergetic Phototherapy of Hypoxic Tumors
Pd nanosheets (Pd NSs) have attracted extensive attention due to their promising application in photothermal therapy. However, their photodynamic properties have rarely been reported. Herein, holey Pd NSs (H-Pd NSs) with intrinsic photodynamic and hypoxia-resistant capacities are fabricated for the first time using an anisotropic oxidative etching strategy, which introduces one-dimensional nanoholes with active (100) facets on the hole walls.
Covalent immobilization of halohydrin dehalogenase for efficient synthesis of epichlorohydrin in an integrated bioreactor
Halohydrin dehalogenase (HHDH)‐mediated dehalogenation of 1,3‐dichloro‐2‐propanol (1,3‐DCP) is a key step in the chemoenzymatic synthesis of epichlorohydrin (ECH) from glycerol. In this study, a covalent immobilization strategy was employed to enhance the stability of Agrobacterium tumefaciens HHDH using epoxy resin ES‐103B as a carrier. Under optimal conditions, the activity recovery of ES‐103B‐immobilized HHDH (HHDH@ES‐103B) was 62.4% and the specific activity was 1604 U/g.
