Summary: Magnetic bismuth ferrite (BiFO) microparticles were used to remove polystyrene (PS) nano/microplastics from drinking water using a combination of photocatalysis and physical adsorption. The BiFO microparticles were able to attract and melt the PS particles, while the generated oxidizing agents degraded the byproducts. After the separation of the BiFO microparticles, a complete removal of PS particles and high mineralization of byproducts were achieved. This study demonstrates the effectiveness of the photocatalysis + physical adsorption strategy for the removal of microplastic contaminants from water.

Summary: This study investigated the toxicity of florfenicol (FF) and polystyrene microplastics (PS-MPs) on rice seedlings. FF and PS-MPs caused colloidal agglomeration, changing the behavior of FF. FF inhibited rice growth, altered antioxidant enzyme activities, impaired photosynthetic systems, and down-regulated key photosynthesis related genes. PS-MPs mitigated FF toxicity, with 10 mg/L PS-MPs being the most effective. Metabolomic analysis revealed significant alterations in metabolites and metabolic pathways, particularly in phenylalanine metabolism and the citric acid cycle.

Summary: This study investigated the embedding of water-soluble poly(maleic anhydride-alt-acrylic acid) polymer in poly(2-hydroxyethyl methacrylate) cryogels, followed by immobilization of copper ions for adsorption of hemoglobin from aqueous systems. The adsorption capacity value obtained was approximately 448.62 mg hemoglobin/g polymer. The same material maintained 90.3% of its adsorption ability even after five cycles of adsorption/desorption. The adsorption interaction was suitable for the Langmuir model, with a calculated change in Gibbs free energy value of -2.168 kJ/mol.

Summary: A novel cellulose phosphonate/polyethyleneimine composite (MCCP-PEI) with abundant nano-porous structure, strong chelating sites, and excellent hydrophilicity was successfully prepared. MCCP-PEI showed rapid adsorption of Cu(II) and Pb(II) heavy metal ions and exhibited saturated adsorption capacities of 250.0 and 534.7 mg center dot g- 1, respectively. The adsorption mechanism was found to be chemical complexation and electrostatic attraction, with the phosphonate group playing a key role.

Summary: Whole genome sequencing is a useful tool for monitoring resistance mechanisms in bacteria. This retrospective study found that the major resistance mechanisms in linezolid-resistant Staphylococcus epidermidis (LRSE) were mutations in 23S rRNA and the presence of the cfr gene, with most LRSE isolates showing high resistance levels to linezolid. Linezolid usage was identified as the main factor contributing to the development of resistance, and monitoring of the cfr gene in LRSE and restriction of linezolid usage are potential key steps to reduce resistance and transmission.

Summary: Inflammation and thrombosis are closely related in various diseases, including ischemic events, sepsis, and COVID-19. Activated neutrophils, platelets, and other factors drive immunothrombosis. Research has shown that the use of heparin-functionalized adsorbents can effectively remove central effectors of immunothrombosis.

Summary: Heavy metals and their compounds are classified as one of the most toxic substances to human health, commonly entering the human body through air, water, and food. While some are naturally present in the environment, more often they pollute it due to anthropogenic activities. Limited medical agents are available for the treatment of acute heavy metal poisoning, and there is currently no specific treatment for chronically exposed individuals.

Summary: Healthcare is undergoing major transformations, necessitating the use of new technologies to support personalized medicine and disease prevention. Biomarkers in bodily fluids such as blood, urine, sweat, or saliva can be used for early diagnosis, disease monitoring, and predicting response to treatment. The development of non-invasive analysis methods has been driven by the need for patients to use and apply diagnostic approaches themselves. This review focuses on novel sensing systems for detecting various endogenous biomarkers associated with human diseases in bodily fluids and exhaled breath.

Summary: Activated platelets and platelet-derived extracellular vesicles play central roles in thromboembolic complications associated with severe COVID-19, but dysregulated platelet activation can lead to immunothrombosis. Activated platelets stimulate neutrophil activation through the release of mediators, resulting in abnormal activation of inflammation and coagulation processes.

Summary: In this study, blood-compatible matrices were developed by surface modification with polyzwitterionic polysulfobetainic and polycarboxybetainic coatings. The coating enhanced the blood compatibility of hydrophobic adsorbents, while had little effect on hydrophilic adsorbents. The coating maintained the adsorption capacity and reduced the activation of blood cells.
