Summary: The Dot/Icm type IV secretion system of Legionella pneumophila is crucial for lysosomal evasion and macrophage permissiveness, but polymorphonuclear cells (PMNs) respond to this system by rapidly restricting the pathogen. This response is triggered by the injected amylase effector, LamA, which catalyzes glycogen degradation in PMNs and leads to immunometabolic reprogramming involving increased aerobic glycolysis. Activated PMNs utilize major microbicidal processes, including granule fusion and reactive oxygen species production, resulting in rapid killing of Legionella pneumophila.

Summary: A simple strategy was provided to regulate the morphology and microstructure of (5-MnO2 via the hydrothermal reaction temperature, which improved the reactivity and lifetime of catalysts in the catalytic ozonation of toluene. The optimized MnO2-260 catalyst showed high catalytic activity and excellent stability at the approximately ambient temperature of 40 degrees C. Surface oxygen vacancy clusters, especially surface oxygen dimer vacancies, were found to be critical in ozone activation.

Summary: Ocean warming has a significant impact on microbes, and the lifestyle (such as free living or biofilm associated) affects the bacterial response to temperature increase. Biofilm formation stabilizes the metabolism of Leisingera aquaemixtae M597 under high temperature, and this stability is likely related to the glycolytic pathways.

Summary: Polyethylene (PE) is a highly durable synthetic material that is widely distributed in nature as a pollutant. This study found that a hydrocarbon-degrading bacterium in the plastisphere is capable of reducing the molecular weight of PE and inducing metabolic pathways for aliphatic compound degradation. These findings suggest that hydrocarbon-degrading bacteria may play a role in the biodegradation of PE.

Summary: In this study, a simple, green, and environmentally friendly strategy using biochar loaded with self-emulsifying orange peel essential oil (BC/SE-OPEO) was proposed to efficiently adsorb and degrade the aromatic amine p-phenylenediamine (PPD). The results showed that the PPD removal efficiency of 50 mg BC/SE-OPEO reached 98% after 110 min at 40 °C. Mechanistic investigations revealed that reactive oxygen species (ROS) played a vital role in the degradation of PPD, which was eventually degraded to carbon dioxide and water.

Summary: ATP exposure leads to a sharp decrease in glutathione (GSH) levels in macrophages, triggering NLRP3 inflammasome activation. Exogenous addition of GSH or GSSG can inhibit GSH efflux and attenuate NLRP3 inflammasome activation. This finding may contribute to the development of novel therapeutic strategies for NLRP3 inflammasome-associated disorders.

Summary: Francisella tularensis is a highly infectious Gram-negative bacterial pathogen classified as a high-priority pathogen due to its pathogenicity and potential public health impact. Tolfenpyrad, a pesticide, was found to be an effective inhibitor of F. tularensis growth. Whole-genome sequencing identified mutations in two genes that conferred resistance to tolfenpyrad, providing insight into the pathways targeted by the drug.

Summary: This study investigates the reaction mechanism of NQ oxidation of H2S to produce RSS using various experimental methods. The results show that NQ can oxidize H2S to per- and polysulfides, consuming oxygen and being accelerated by SOD while inhibited by catalase.

Summary: This study proposes a novel sonosensitizer, an oxygen-deficient piezoelectric nanocomposite. This material, with oxygen defect engineering and Schottky junction modified by bismuth nanoparticles, can efficiently generate reactive oxygen species under ultrasound irradiation, enhancing tumor cell apoptosis and exerting anti-tumor activity through the extracellular matrix disassembly pathway.

Summary: Advanced maternal age leads to an increase in meiotic chromosome segregation errors, resulting in early miscarriages and congenital disorders; The integrity of the spindle assembly checkpoint decreases rapidly with maternal age, contributing to increased chromosome segregation errors; AURKB may play a novel protective role in preserving female reproductive lifespan by safeguarding oocytes from oxidative stress.

Summary: The ancient DNA study of a child's remains from a late mediaeval cemetery in Taunton, UK, confirmed a diagnosis of tuberculosis, with sex determination suggesting a young male child. This case represents a rare description of childhood tuberculosis from this period and sheds light on the likely presence of tuberculosis in the adult population of the mediaeval era served by this cemetery.

Summary: M.leprae is a causative agent of human leprosy and exhibits phylogeography like other pathogens, providing insights into disease origins and ancient human migration routes. A study confirmed the presence of an M.leprae SNP-type 3 strain in a skeleton from a 10th-11th century individual in the UK, indicating the leprosy subtype and potential ancestral relationships to modern genotypes.
