Nitrogen Transformation Survival Strategies of Ammonia-Oxidizing Bacterium N.eA1 Under High Nitrite Stress

open access: yesSustainability
Ammonia-oxidizing bacteria (AOB) are key to the nitrogen cycle, but their resistance to nitrite (NO2−-N) accumulation is unclear. This study examined N.eA1, an AOB from the completely autotrophic nitrogen removal over nitrite (CANON) process, assessing its adaptive responses to NO2−-N.

Pemt Inhibition‐Mediated Vdac1 Oligomerization Regulates Mitochondrial Dysfunction, Apoptosis, and Inflammation in High‐Fat Diet‐Derived Liver Injury

open access: yesAdvanced Science, EarlyView.
ABSTRACT High‐fat diet (HFD)‐induced hepatic injury represents a pathology observed across vertebrates, yet the underlying mechanisms remain incompletely understood. Herein, the present study identifies phosphatidylethanolamine methyltransferase (Pemt), a key enzyme in phosphatidylcholine synthesis, as a critical regulator of mitochondrial homeostasis ...

Vascularized Liver‐on‐a‐Microsphere Reveals Alanine‐Glucose Metabolism‐Driven Regulation of Liver Function and Injury

open access: yesAdvanced Science, EarlyView.
A vascularized liver‐on‐a‐microsphere system is developed to recreate lobule‐like cellular organization and endothelial barrier function within compartmentalized hydrogel particles. The platform enhances hepatic performance and reveals alanine‐glucose cycle activation linked to improved detoxification capacity, offering a high‐throughput microscale ...

Non-Invasive Characterization of Locomotor and Ventilatory Responses in Rainbow Trout Under Acute Ammonia Nitrogen Stress

open access: yesBiology
Ammonia nitrogen is one of the most common environmental stressors in aquaculture water environments, and its accumulation can induce physiological disturbance, altered ventilation regulation, and abnormal behavioral responses in fish.

ZrO2 Aerogel‐Supported Pd Nanoparticles for Photothermal CO2 Reduction

open access: yesAdvanced Science, EarlyView.
Nanoparticle‐based aerogels are promising catalysts for photothermal reactions due to optical transparency, high surface area, and low thermal conductivity. Here, we present deposition of Pd nanoparticles on ZrO2 aerogel granules by a wet‐impregnation approach.

Light‐Activated Ruthenium Nanoclusters Reprogram the Metabolic‐Quorum Sensing Axis for Precision Periodontitis Therapy

open access: yesAdvanced Science, EarlyView.
Under 660 nm visible light, Ru NCs efficiently photocatalyze nitrate‐to‐ammonium conversion and modulate oral nitrogen metabolism. They precisely perturb Veillonella parvula, block its key support to Porphyromonas gingivalis, and exert an “inhibiting without killing” antivirulence effect.

Effects of ammonia nitrogen stress on liver tissue structure and physiological indicators, and metabolomic analysis of juvenile four-finger threadfin (Eleutheronema tetradactylum)

open access: yesFrontiers in Marine Science
In intensive aquaculture, ammonia nitrogen (NH₃-N) is a major pollutant, causing oxidative stress and immune damage to aquatic organisms. The liver is crucial in protecting against biotic and abiotic stresses, but the response mechanisms to ammonia ...
