In this paper, a tumor-targeted near-infrared/ultraviolet (NIR/UV) triggered PTT/GT synergistic therapeutic nanoplatform, PB-CD-PLL(NF)-FA, was designed based on Prussian blue (PB) nanoparticles, 5-chloro-2-nitrobenzotrifluoro (NF)-grafted polylysine (PLL(NF)), and folic acid (FA). PB serves as a core to load PLL(NF) through host-guest interaction and can further modify FA.

Herein, we design and develop a photocatalytic system composed of two separate reaction parts: a hydrogen evolution cell containing halide perovskite photocatalysts (MoSe-loaded CH(NH)PbBrI) and an oxygen evolution cell containing NiFe-layered double hydroxide modified BiVO photocatalysts. These components are bridged by a I/I redox couple to facilitate electron transfer, realizing efficient overall water splitting with a solar-to-hydrogen conversion efficiency of 2.

However, the calcium buffering capacity of tumor cells can maintain mitochondrial calcium homeostasis, so it is important to effectively disrupt this homeostasis to activate pyroptosis. Here, a nano-modulator CUR@CaCO-PArg@HA (CCAH) was developed to regulate calcium overload in multiple channels and activate pyroptosis.

In this study, the effects of four commonly used antibiotics (sulfadiazine, ciprofloxacin, erythromycin, and ampicillin) on the mineralization of OP were explored using16S rRNA gene sequencing technology. The results showed that ciprofloxacin, erythromycin, and ampicillin negatively affected the mineralization capacity of OP, whereas sulfadiazine positively influenced OP mineralization.

However, the mutual constraints of stealth principles across different bands and the demand for environment-adaptive camouflage raise challenges to existing multispectral compatible stealth solutions. Here a multifunctional-hierarchical flexible metasurface (MHFM) including an infrared suppression layer (IRSL), three microwave absorbing layers (MAL), an environmental adaptation layer (EAL), and a total reflective sheet (TRS), was designed to simultaneously achieve IR, radar, and dynamic visible stealth.

Using voxel-based morphometry (VBM) and region of interest (ROI) analysis, gray matter volumes (GMV) were compared in the contralesional primary motor gyrus, primary sensory gyrus, premotor area, bilateral supplementary motor area, and medial Brodmann area 8 (BA8). The results revealed that in patients with right hemisphere gliomas, the right medial BA8 volume was significantly larger in the impaired group than in the unimpaired group, with both groups exceeding the volume in 16 healthy controls (HCs).

The results revealed that the inoculation of combined bacteria induced quorum sensing, modulated hydrolytic enzyme production, and reshaped the community structure. Lignin-degraded genera (Pseudomonas and Sphingobacterium) were enriched, and the relative abundances of pectin- and cellulose-degraded genera (Chryseobacterium) decreased in the early degumming stages.

A stereolithography process with thermal assistance is proposed in this work to address the tradeoff between the flowability and the high concentration of solute loadings at room temperature, through which the improved performance of polymers prepared using stereolithography 3D printing can be achieved. For the experiment, polyethylene glycol diacrylate (PEGDA) with a high molecular weight of 4000 is adopted to improve the mechanical properties of 2-Hydroxyethyl methacrylate (HEMA). For the polymer of HEMA, the highest soluble concentration of PEGDA is about 20 wt% at 25 °C (room temperature) while the concentration could be raised up to 40 wt% as the temperature increases to 60 °C.
