Preparation of capecitabine-poly(p-dioxanone) electrospraying nanoparticles and influence of particle size on their colorectal cancer inhibitive efficiency.

Colorectal cancer is the fourth leading cause of cancer-related deaths worldwide. Capecitabine is a chemotherapeutic agent commonly used for the treatment of colon cancer. To realize local sustained release, promote efficient local intracellular transport, and mitigate the systemic toxic effects of capecitabine, a capecitabine prodrug, capecitabine-poly (p-dioxanone) (Cap-PPDO), was successfully synthesized.

Quantum Well Superlattice Heteronanostructures for Efficient Photocatalytic Hydrogen Evolution.

In this study, we construct a quantum well effect-based two-dimensional Z-scheme superlattice heteronanostructure photocatalyst constructed from hydrogen-bonded porphyrin organic frameworks (HOFs) and carbon nitride. Porphyrin HOFs extend spectral absorption, while their π-conjugation and electron density variations significantly enhance charge separation and exhibit favorable alignment with the energy levels of carbon nitride, thereby enabling efficient charge transfer. Carboxylic acid channels in the HOFs further promote the decomposition of water molecules, thereby boosting hydrogen production.

Low-Cost, Facile, and Scalable Manufacturing of Single-Molecule-Integrated Catalytic Electrodes.

To surmount the shortcomings of powder-based catalysts and small electrode sizes, the development of meter-scale integrated electrode materials is essential for practical electrocatalytic applications, which requires fine control over the effective surface grafting of catalytic active sites on large-size electrodes as well as addressing the challenge of balancing cost-effective and large-scale manufacturing with highly active and stable operation. Herein, we report a low-cost, facile, and scalable method for directly constructing meter-scale single-molecule-integrated catalytic electrodes using commercially available, flexible, and size-tailored conductive carbon textiles (e.g.

Statistical inference on change points in generalized semiparametric segmented models.

The segmented model has significant applications in scientific research when the change-point effect exists. In this article, we propose a comprehensive semiparametric framework in segmented models to test the existence and estimate the location of change points in the generalized outcome setting. The proposed framework is based on a semismooth estimating equation for the change-point estimation and an average score-type test for hypothesis testing.

Two-Year Hypertension Incidence Risk Prediction in Populations in the Desert Regions of Northwest China: Prospective Cohort Study.

Background: Hypertension is a major global health issue and a significant modifiable risk factor for cardiovascular diseases, contributing to a substantial socioeconomic burden due to its high prevalence.

The resultant KTi(PO)@N-doped carbon composite (KTP@NC) exhibits a preserved porous structure with abundant pores, facilitating ion diffusion and electrolyte infiltration. Various characterizations, including X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and Raman spectroscopy, reveal the successful formation of an interconnected nitrogen-doped carbon network.

Position-dependent resource competition within inflorescences of Sagittaria trifolia.

Resource competition among flowers is expected to influence variation in seed output within inflorescences, but the extent to which flower position affects competitive interactions is still incompletely understood. To investigate position effects on seed output in the perennial, monoecious macrophyte Sagittaria trifolia, we compared components of seed production (fruit set, seed number per fruit, and seed size) in control inflorescences to that in inflorescences from which half of the female flowers were experimentally removed, either from basal positions, from upper positions, or from across the inflorescence. Basal and upper flower removal reduced total seed output per inflorescence, while the throughout removal treatment maintained a seed yield comparable to the control.

Trifluoroacetic Acid Induced a Cyclophilin D-Dependent Cognitive Impairment in Mice.

Studies have linked inhalation anesthesia and surgery to increased cognitive impairment, particularly in the elderly. Our previous research showed that isoflurane, but not desflurane, affected cognitive function in mice by modulating cyclophilin D (CypD), a key regulator of the mitochondrial permeability transition pore (mPTP) and mitochondrial function. Both anesthetics metabolize into trifluoroacetic acid (TFA), which is associated with cognitive deficits.
