This study investigates the association between irAEs and ICI outcomes in patients with recurrent or metastatic nasopharyngeal carcinoma (R/M NPC).

Methods: A post hoc analysis was performed on 153 patients with R/M NPC who received anti-PD-L1 inhibitors between February 26, 2019, and January 13, 2021.

Tailoring Robust 2D Nanochannels by Radical Polymerization for Efficient Molecular Sieving.

Two-dimensional (2D) nanochannels have demonstrated outstanding performance for sieving specific molecules or ions, owing to their uniform molecular channel sizes and interlayer physical/chemical properties. However, controllably tuning nanochannel spaces with specific sizes and simultaneously achieving high mechanical strength remain the main challenges. In this work, the inter-sheet gallery d-spacing of graphene oxide (GO) membrane is successfully tailored with high mechanical strength via a general radical-induced polymerization strategy.

Aberrant brain structural-functional coupling and structural/functional network topology explain developmental delays in pediatric Prader-Willi syndrome.

Prader-Willi syndrome (PWS) is a neurodevelopmental disorder characterized by dysplasia in early life. Psychoradiology studies have suggested that mental and behavioral deficits in individuals with PWS are linked to abnormalities in brain structural and functional networks. However, little is known about changes in network-based structural-functional coupling and structural/functional topological properties and their correlations with developmental scales in children with PWS.

YTHDF2 promotes ATP synthesis and immune evasion in B cell malignancies.

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.

N, S-Codoped Carbon Quantum Dots with High Inhibition Efficiency: Implications for Corrosion Mitigation of Carbon Steel in Acidic Environments.

The environmental friendliness, economic feasibility, and high efficiency of carbon quantum dots (CQDs) render them as highly promising candidates for corrosion inhibitors. The present study proposed the fabrication of nitrogen- and sulfur-codoped CQDs via an one-step hydrothermal method using l-cysteine and 4-aminosalicylic acid as precursors. The structure, particle size, and surface ligands of the prepared CQDs were determined through spectroscopy and transmission electron microscopy characterization.

One-step detection of nanoplastics in aquatic environments using a portable SERS chessboard substrate.

Nanoplastics present a significant hazard to both the environment and human health. However, the development of rapid and sensitive analysis techniques for nanoplastics is limited by their small size, lack of specificity, and low concentrations. In this study, a surface-enhanced Raman scattering (SERS) chessboard substrate was introduced as a multi-channel platform for the pre-concentration and detection of nanoplastics, achieved by polydomain aggregating silver nanoparticles (PASN) on a hydrophilic and a punched hydrophobic PVDF combined filter membrane.

Lhx6 deficiency causes human embryonic palatal mesenchymal cell mitophagy dysfunction in cleft palate.

Background: Overconsumption of retinoic acid (RA) or its analogues/derivatives has been linked to severe craniomaxillofacial malformations, such as cleft palate and midface hypoplasia. It has been noted that RA disturbed the proliferation and migration of embryonic palatal mesenchymal (EPM) cells in these malformations, yet the exact mechanisms underlying these disruptions remained unclear.

Methods: A model of retinoic acid (RA)-induced cleft palate in fetal mice was successfully established.

Combined HDAC8 and checkpoint kinase inhibition induces tumor-selective synthetic lethality in preclinical models.

The elevated level of replication stress is an intrinsic characteristic of cancer cells. Targeting the mechanisms that maintain genome stability to further increase replication stress and thus induce severe genome instability has become a promising approach for cancer treatment. Here, we identify histone deacetylase 8 (HDAC8) as a drug target whose inactivation synergized with the inhibition of checkpoint kinases to elicit substantial replication stress and compromise genome integrity selectively in cancer cells.

E2F8-TPX2 axis regulates glycolysis and angiogenesis to promote progression and reduce chemosensitivity of liver cancer.

Unlabelled: Liver cancer (LC) is a global health concern, marked by its high prevalence and mortality rates and known for its resistance to chemotherapy. The treatment of LC patients is facing great challenges. Targeting protein for Xenopus kinesin-like protein 2 (TPX2) is a LC marker that has been discovered in recent years, and there are sporadic data suggesting that it has an impact on the level of chemoresistance, but the exact mechanism remains to be deciphered.
