Hypoxia, high ROS levels and chronic inflammation are the main factors that hinder the healing of diabetic wounds. Long-term exposed wounds are prone to bacterial infection, especially MRSA infection, which exacerbates the complex wound microenvironment of diabetes and threatens patients' lives. Here, we developed a ROS nanopurifier (CSVNP), which was prepared by loading superoxide dismutase (SOD), catalase (CAT) and vancomycin into nanogels through in-situ polymerization.

Lignin serves as an ideal substrate for the synthesis of chemically functionalized hyper-cross-linked resins due to the structural composition of its aromatic rings, aliphatic side chains, and multiple active functional groups. These resins have shown to be highly effective in the adsorption of aromatic compounds. In this study, hyper-cross-linked polymer (HCPs-3), synthesized using 1,3,5-triphenyl and lignin, demonstrated a significant adsorption capacity for aniline, with a maximum adsorption capacity (q) of 189.

Background: Understanding the impact of asthma on public health is crucial for evidence-based prevention and treatment strategies.
Objective: This study aimed to identify the causes of asthma-related mortality in Pudong, Shanghai, China, offering insights for managing similar regions or countries in transition.
Methods: Mortality statistics were obtained from the Vital Statistics System of Pudong for 2005-2021.
Background: Dysbiosis of gut microbiota (GM) is intricately linked with cognitive impairment and the incidence of traumatic brain injury (TBI) in both animal models and human subjects. However, there is limited understanding of the impact and mechanisms of fecal microbiota transplantation (FMT) on brain and gut barrier function in the treatment of TBI induced by gas explosion (GE).
Methods: We have employed FMT technology to establish models of gut microbiota dysbiosis in male rats, and subsequently conducted non-targeted metabolomics and microbiota diversity analysis to explore the bacteria with potential functional roles.

An inverted DNA tetrahedron-mediated modular DNA walker was developed for the determination of sulfadimethoxine. The inverted DNA tetrahedron scaffold raises several advantages of recognition module including appropriate lateral space, multiple recognition domains, and cost-effectiveness. The proposed inverted DNA tetrahedron-based recognition module exhibited better binding affinity and kinetics toward target antibiotic than that of other DNA tetrahedron counterparts.

Our experiments support the development of a compact Sr optical-lattice clock, which leverages magneto-optical trapping at 461 nm and 689 nm without bulk free-space optics. We integrate six mm-scale metasurfaces on a fused silica substrate and illuminate them with light from optical fibers.

However, the lack of subcellular specificity, high ion concentrations, and long incubation time required for biomineralization still limit its therapeutic efficacy. Herein, we report a mitochondria-targeted polymer-gold complex (TPPM-Au) to realize mitochondrial biometallization, which involves analogous mechanisms during biomineralization, for cancer treatment .

Pervasive environmental pollutants, specifically particulate matter (PM), possess the potential to disrupt homeostasis of female thyroid hormone (TH). However, the precise mechanism underlying this effect remains unclear. In this study, we established a model of PM-induced thyroid damage in female rats through intratracheal instillation and employed histopathological and molecular biological methods to observe the toxic effects of PM on the thyroid gland.

To address the challenge of better extracting semantic information and ad-dressing class imbalance in multiclass segmentation, we propose utilizing diffusion models for remote sensing image semantic segmentation, along with a lightweight classification module based on a spatial-channel attention mechanism. Our approach incorporates unsupervised pretrained components with a classification module to accelerate model convergence.

However, strategies using bulk chemicals are rare because of the challenge of breaking two unactivated geminal bonds. Herein, we report the reactivity of ethers to form metal-carbene intermediate by cleavage of α-C-H/C-O bonds, which achieve selective coupling with arylmagnesium bromides and chlorosilanes.

This study aims to thoroughly investigate the impact of protease addition on the growth performance, intestinal function, and microbial composition of weaned piglets. Ninety 28-day-old weaned pigs were randomly assigned to the following three experimental diets based on their initial body weight for a 28-day experiment: (1) control (CC), a basic diet with composite enzymes without protease; (2) negative control (NC), a diet with no enzymes; and (3) dietary protease (PR), a control diet with protease.

Here, we report the generation of the ketyl radicals and coupling with alkynes that was enabled by cost-effective chromium catalysis, allowing for the formation of valuable -exocyclic allyl alcohols with high stereo- and chemoselectivity. A broad range of synthetically useful functional groups that are sensitive to strong reductants are compatible with the catalytic system, providing access to diverse substituted -exocyclic allyl alcohols under mild conditions.

Intricate regulatory mechanisms must exist that modulate inflammation, while controlling the infection. Here, B cells expressing choline acetyl transferase (ChAT), an enzyme required for production of the metabolite and neurotransmitter acetylcholine (ACh) are identified as such regulators of the immediate early response to influenza A virus.

The opening or closing of these channels can impact mitochondrial function and structure by interfering with intracellular ion homeostasis, thereby regulating cell fate. Nevertheless, their abnormal expression or regulation poses challenges in eliminating cancer cells, and further contributes to metastasis, recurrence, and drug resistance.
