Orchestrated copper-loaded nanoreactor for simultaneous induction of cuproptosis and immunotherapeutic intervention in colorectal cancer.

Ion interference, including intracellular copper (Cu) overload, disrupts cellular homeostasis, triggers mitochondrial dysfunction, and activates cell-specific death channels, highlighting its significant potential in cancer therapy. Nevertheless, the insufficient intracellular Cu ions transported by existing Cu ionophores, which are small molecules with short blood half-lives, inevitably hamper the effectiveness of cuproptosis. Herein, the ESCu@HM nanoreactor, self-assembled from the integration of H-MnO nanoparticles with the Cu ionophore elesclomol (ES) and Cu, was fabricated to facilitate cuproptosis and further induce relevant immune responses.

Sensitive detection of gallic acid in food by electrochemical sensor fabricated by integrating nanochannel film with nanocarbon nanocomposite.

Sensitive detection of gallic acid (GA) in foods is of great significance for assessing the antioxidant properties of products and ensuring consumer health.

A water-soluble mixture of graphene oxide (GO) and NGQDs was drop-cast onto the common carbon electrode, glassy carbon electrode (GCE), followed by rapid growth of VMSF using an electrochemically assisted self-assembly method (EASA).

Amino-functionalized vertically ordered mesoporous silica film on electrochemically polarized screen-printed carbon electrodes for the construction of gated electrochemical aptasensors and sensitive detection of carcinoembryonic antigens.

Disposable electrochemical biosensors with high sensitivity are very fit for point-of-care testing in clinical diagnosis. Herein, amino-functionalized, vertically ordered mesoporous silica films (NH-VMSF) attached to an electrochemically polarized screen-printed carbon electrode (p-SPCE) are prepared using a simple electrochemical method and then utilized to construct a gated electrochemical aptasensor for rapid and sensitive determination of carcinoembryonic antigen (CEA). After being treated with the electrochemical polarization procedure, p-SPCE has plentiful oxygen-containing groups and improved catalytic ability, which help promote the stability of NH-VMSF on SPCE without the use of an adhesive layer and simultaneously generate a highly electroactive sensing interface.

A primary intracranial neuroepithelial neoplasm with novel TCF3::BEND2 fusion: a case report.

Astroblastoma, MN1-altered, is a rare circumscribed glial neoplasm that is composed of round, cuboidal, orcolumnar cells with astroblastic perivascular pseudorosettes, often associated with MN1::BEND2 and MN1::CXXC5 fusions. Atroblastoma-like gliomas harbouring EWSR1::BEND2 have been reported that they defined an epigenetically distinct subtype of astroblastoma. We report a case of a 19-year-old female with an intracranial neuroepithelial tumor featuring a novel TCF3::BEND2 fusion.

Effects of Postharvest SO Treatment on Longan Aril Flavor and Glucosinolate Metabolites.

SO fumigation treatment (commonly known as sulfur treatment, ST) is a key method in the postharvest preservation of imported and exported fresh longan fruits, effectively reducing pericarp browning and enhancing color.

Tuning Proton Affinity on Co-N-C Atomic Interface to Disentangle Activity-Selectivity Trade-off in Acidic Oxygen Reduction to HO.

In oxygen reduction reaction to HO via two-electron pathway (2e ORR), adsorption strength of oxygen-containing intermediates determines both catalytic activity and selectivity. However, it also causes activity-selectivity trade-off. Herein, we propose a novel strategy through modulating the interaction between protons and *OOH intermediates to break the activity-selectivity trade-off for highly active and selective 2e ORR.

Therapeutic effects of Mudan granules on diabetic retinopathy: Mitigating fibrogenesis caused by FBN2 deficiency and inflammation associated with TNF-α elevation.

Exploration of the shared gene signatures and comorbidity mechanisms of primary aldosteronism and atrial fibrillation.

Background: Primary aldosteronism (PA) is a prevalent cause of endocrine hypertension characterized by an excess of aldosterone that can induce proinflammatory, prooxidant and profibrotic effects on the heart. Emerging evidence indicates a heightened incidence of atrial fibrillation (AF) in patients with PA, suggesting a significant association between the two conditions. However, the underlying mechanisms remain unclear.
