Application


  • Sex differences in cholinergic signaling affect functional outcomes for theta-gamma coordination in hippocampal subcircuits following experimental febrile status epilepticus.: This study uses urethane anesthesia to investigate the impact of sex differences on cholinergic signaling in the hippocampus, shedding light on neurological responses and potential therapeutic targets (Kloc et al., 2024).

  • Postinspiratory and preBötzinger complexes contribute to respiratory-sympathetic coupling in mice before and after chronic intermittent hypoxia.: Urethane is utilized in this study to explore respiratory and sympathetic nervous system interactions, providing insights into adaptive physiological mechanisms (Karlen-Amarante et al., 2024).

  • Instant clot forming and antibacterial wound dressings: Achieving hemostasis in trauma injuries with S-nitroso-N-acetylpenicillamine-tranexamic acid-propolis formulation.: This paper presents innovative urethane-based wound dressings that offer rapid clot formation and antibacterial properties, crucial for trauma care (Nguyen et al., 2024).
