DGKζ in Glycerophospholipid Metabolism Regulates the DAG and PA Balance and Interacts With PTEN to Alleviate Brain Damage in Septic Mice With Hydrogen Inhalation: A Comparative Metabolomic and Phosphoproteomic Analysis

Brain and Behavior, Volume 15, Issue 8, August 2025.
H2 downregulates DGKζ and CCTα to alleviate brain damage in septic mice. The change in DGKζ has been shown to balance the transformation between DAG and PA, and it may also interact with PTEN. ABSTRACT Objectives: Therapeutic effects of hydrogen (H2) on sepsis‐associated encephalopathy (SAE), a severe neuroinflammatory disease, have been reported, but ...

Eutrophication triggers diel and seasonal shifts of carbon dioxide and oxygen in tropical urban coastal waters

Limnology and Oceanography Letters, Volume 10, Issue 3, Page 329-339, June 2025.
Abstract Coastal waters play a pivotal role in the global carbon cycle, showing increased short‐term variability of dissolved oxygen saturation (DOsat) and partial pressure of greenhouse gases like carbon dioxide (pCO2), especially in underrepresented tropical eutrophic environments.
