This process ensures full utilization of raw materials, effectively reduces water consumption, and simplifies the operating process.

PAMAM/miR-144 nanocarrier system inhibits the migration of gastric cancer by targeting mTOR signal transduction pathway.

Exogenous microRNA-144 (miR-144) is considered as a potential biological drug for gastric cancer because of its biological activity to inhibit the epithelial-mesenchymal transition (EMT). However, the specific molecular mechanisms have not been fully revealed. In addition, their vulnerability to degradation by RNA enzymes in the blood limits their bioavailability.

Transketolase attenuates the chemotherapy sensitivity of glioma cells by modulating R-loop formation.

Glioblastoma (GBM) is a highly lethal malignant brain tumor with poor survival rates, and chemoresistance poses a significant challenge to the treatment of patients with GBM. Here, we show that transketolase (TKT), a metabolic enzyme in the pentose phosphate pathway (PPP), attenuates the chemotherapy sensitivity of glioma cells in a manner independent of catalytic activity. Mechanistically, chemotherapeutic drugs can facilitate the translocation of TKT protein from the cytosol into the nucleus, where TKT physically interacts with XRN2 to regulate the resolution and removal of R-loops.

Selective Adsorption of Chlorine Species on RuO Sites for Efficient Elimination of Vinyl Chloride on the Ru/SnO Catalyst.

The main bottleneck in the catalytic combustion of chlorinated volatile organic compounds (CVOCs) is deactivation and the production of chlorine-containing byproducts originating from the chlorine species deposited on the catalyst. Herein, Ru supported on SnO (Ru/SnO) was prepared with the lattice matching principle. As RuO and SnO are both rutile phases, Ru species were present as highly dispersed RuO particles on the Ru/SnO catalyst.

Hemodynamic evaluation of symptomatic and asymptomatic intracranial atherosclerotic stenosis using cerebral angiographic images: an exploratory study.

Background: Previous studies suggest that it may be inappropriate to determine treatment strategies solely based on the degree of stenosis for patients with intracranial atherosclerotic stenosis (ICAS).

Constructing Atomic Tungsten-Based Solid Frustrated-Lewis-Pair Sites with d-p Interactions for Selective CO Photoreduction.

Solid frustrated Lewis pair (FLP) shows remarkable advantages in the activation of small molecules such as CO, owing to the strong orbital interactions between FLP sites and reactant molecules. However, most of the currently constructed FLP sites are randomly distributed and easily reunited on the surface of catalysts, resulting in a low utilization rate of FLP sites. Herein, atomic tungsten-based FLP (N···W FLP) sites are constructed for photocatalytic CO conversion through introducing W single-atoms into polymeric carbon nitride.

Embedded 3D printing of engineered lung cancer model for assisting fine-needle aspiration biopsy.

Lung cancer is a serious global health issue that requires the development of patient-specific, lung cancer model for surgical planning to train interventionalists and improve the accuracy of biopsies. Although the emergence of three-dimensional (3D) printing provides a promising solution to create customized models with complicated architectures, current 3D printing methods cannot accurately duplicate anatomical-level lung constructs with tumor(s) which are applicable for hands-on training and procedure planning. To address this issue, an embedded printing strategy is proposed to create respiratory bronchioles, blood vessels, and tumors in a photocurable yield-stress matrix bath.

Magneto-Photonic Effect of FeO@SiO Nanorods for Visualizing the Direction of Magnetic Fields with High Spatiotemporal Resolution.

In this work, we demonstrate the visualization of the complex magnetic fields by utilizing the magneto-photonic effect of FeO@SiO nanorod suspension with one-to-one correspondence between the visible colors and magnetic field directions. The selected anisotropic nanorods possess appropriate saturated magnetization and high electrostatic repulsion, which is magnetically direction-responsive but strength-insensitive, accurately detecting the field direction while eliminating the influence from intensity. The combined experiment-simulation study validates the accuracy of the simulation, allowing us to further determine the intensity distribution of the magnetic field.
