Radioactive molecular iodine (I) is a critical volatile pollutant generated in nuclear energy applications, necessitating sensors that rapidly and selectively detect low concentrations of I vapor to protect human health and the environment. In this study, we design and prepare a three-component sensing material comprising reduced graphene oxide (rGO) as the substrate, silver iodide (AgI) particles as active sites, and polystyrene sulfonate as an additive. The AgI particles enable reversible adsorption and conversion of I molecules into polyiodides, inducing substantial charge density variation in rGO.

Long-term durable remission in patients with B cell malignancies following chimeric antigen receptor (CAR)-T cell immunotherapy remains unsatisfactory, often due to antigen escape. Malignant B cell transformation and oncogenic growth relies on efficient ATP synthesis, although the underlying mechanisms remain unclear. Here, we report that YTHDF2 facilitates energy supply and antigen escape in B cell malignancies, and its overexpression alone is sufficient to cause B cell transformation and tumorigenesis.

is widely used in the laboratory as an infection model for the research on pathogenesis and host defense against gram-positive intracellular bacteria. Macroautophagy (called simply "autophagy" hereafter), is important in the host defense against pathogens, such as bacteria, viruses, and parasites. BECN1 plays a pivotal role in the initiation of autophagy and accumulating evidence indicates that post-translational modifications of BECN1 provide multiple strategies for autophagy regulation.

Heptafluoropropylene oxide dimer acid (HFPO-DA), as an alternative to perfluorooctanoic acid (PFOA), has been shown to pose similar environmental and health risks as other perfluorinated compounds. The electrochemical-based advanced oxidation processes are promising techniques for the treatment of perfluorinated compounds, and the boron-doped diamond (BDD) anode could degrade HFPO-DA under mild conditions. However, the roles of radicals in the degradation and how to overcome the steric hindrance of the -CF branch on the carboxyl group were not yet clear.

Cancer-associated macrophage-like cells (CAMLs) are rare, gigantic, and atypical circulating cells found exclusively in the peripheral blood of patients with solid cancers. Obesity-induced hypoxia attracts macrophages to the tumor microenvironment, where they contribute to establishing chronic inflammation, leading to cancer progression. We hypothesized that obese patients with advanced breast cancer may have CAML profiles different from those of nonobese patients, and these profiles may correlate with proinflammatory markers or other macrophage-related markers.

Article Synopsis
  • The KCNQ1+KCNE1 potassium channel is vital for heart stress adaptation, where β-adrenergic stimulation enhances its activity via phosphorylation, essential for managing increased heart rates.
  • Variants in the KCNQ1 gene can lead to long-QT syndrome type 1 (LQT1), with some mutations making patients more susceptible to serious heart risks, but the details of how phosphorylation affects channel function and cAMP sensitivity are still unclear.
  • Research using techniques like patch clamp and induced pluripotent stem cells revealed key molecular features in LQT1 variants and identified a small molecule, ML277, that can restore function in high-risk mutations by targeting the phosphorylation axis of the channel.

Background: Lung cancer remains one of the most prevalent cancer types worldwide, with a high mortality rate. Upregulation of programmed cell death protein 1 (PD-1) and its ligand (PD-L1) may represent a key mechanism for evading immune surveillance. Immune checkpoint blockade (ICB) antibodies against PD-1 or PD-L1 are therefore widely used to treat patients with lung cancer.
