The pervasive utilization of plastic tools in aquaculture introduces significant volumes of microplastic fibers, presenting a consequential risk through the leaching of additives such as phthalates. This study scrutinizes the leaching dynamics of six prevalent phthalate esters (PAEs) from thirteen plastic aquaculture tools comprising polyethylene terephthalate (PET), polypropylene (PP), and polyethylene (PE), with ΣPAEs ranging from 0.24 to 4.

Ferroptosis nano-inducers have drawn considerable attention in the treatment of malignant tumors. However, low intratumoral hydrogen peroxide level and complex biological barriers hinder the ability of nanomedicines to generate sufficient reactive oxygen species (ROS) and achieve tumor penetration. Here a near-infrared (NIR)-driven ROS self-supplying nanomotor is successfully designed for synergistic tumor chemodynamic therapy (CDT) and photothermal therapy (PTT).

Background: Cataract is the leading cause of blindness worldwide and surgery can restore vision in most patients. Some patients have little access to surgical services due to lack of cataract surgeons and the unaffordable costs. In 2005 we built a service model that trained rural non-ophthalmologist physicians to perform cataract surgeries in rural China.

Macrophages play a pivotal role in orchestrating the immune response against pathogens. While the intricate interplay between macrophage activation and metabolism remains a subject of intense investigation, the role of glutamate oxaloacetate transaminase 1 (Got1) in this context has not been extensively assessed. Here, we investigate the impact of Got1 on macrophage polarization and function, shedding light on its role in reactive oxygen species (ROS) production, pathogen defense, and immune paralysis.

Beryllium-containing sludge (BCS) is a byproduct of the physicochemical treatment of beryllium smelting wastewater. The pollutant element beryllium within BCS is highly unstable and extremely toxic, characterized by its small ionic radius and low charge density, resulting in a high risk of leaching and migration. This study is the first to investigate the leaching behavior, influencing mechanisms, and kinetic processes of beryllium in BCS under various environmental conditions.

More information is needed to fully comprehend how acid mine drainage (AMD) affects the phototransformation of antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in karst water and sewage-irrigated farmland soil with abundant carbonate rocks (CaCO) due to increasing pollution of AMD formed from pyrite (FeS). The results showed FeS accelerated the inactivation of ARB with an inactivation of 8.7 log.

Photodynamic therapy (PDT) is a light-activated local treatment modality that has promising potential in cancer therapy. However, ineffective delivery of photosensitizers and hypoxia in the tumor microenvironment severely restrict the therapeutic efficacy of PDT. Herein, phototactic Chlorella (C) is utilized to carry photosensitizer-encapsulated nanoparticles to develop a near-infrared (NIR) driven green affording-oxygen microrobot system (CurNPs-C) for enhanced PDT.

Introduction: Chronic obstructive pulmonary disease (COPD) represents one of the leading causes of death worldwide. Published clinical trials suggest that the Chinese patent herbal medicine Shufeng Jiedu capsule (SFJD) is safe and may be effective for treating acute exacerbations of COPD (AECOPD). However, these effects have been reported with low or very low certainty evidence.

  • Bacterial AraC is a transcription factor that helps start gene transcription by recruiting RNA polymerase and regulating bacterial traits, but its role in bacterial virulence and host immunity remains unclear.
  • Research on the AraC-like gene orf02889 in the virulent strain LP-2 showed that its deletion increased biofilm and siderophore production while reducing bacterial virulence, indicating it has potential as a vaccine target.
  • Proteomics analysis revealed that ORF02889 influences various metabolic pathways, with further tests confirming that deletion of selected genes significantly reduced virulence in zebrafish, and ChIP-PCR confirmed that ORF02889 directly regulates the promoter of these genes.

T helper type 2 (Th2) cytokine-activated M2 macrophages contribute to inflammation resolution and wound healing. This study shows that IL-4-primed macrophages exhibit a stronger response to lipopolysaccharide stimulation while maintaining M2 signature gene expression. Metabolic divergence between canonical M2 and non-canonical proinflammatory-prone M2 (M2) macrophages occurs after the IL-4Rα/Stat6 axis.
