Dual role of the L-arginine–ADMA–NO pathway in systemic hypoxic vasodilation and pulmonary hypoxic vasoconstriction

Pulmonary Circulation, 2020
In healthy vascular endothelium, nitric oxide acts as a vasodilator paracrine mediator on adjacent smooth muscle cells. By activating soluble guanylyl cyclase, nitric oxide stimulates cyclic guanosine monophosphate (cGMP) which causes relaxation of ...

A ROS‐Responsive and Mucoadhesive Thermosensitive Hydrogel Encapsulated with Mizoribine for Synergistic Dry Eye Therapy

Advanced Science, EarlyView.
The ROS‐responsive in situ thermosensitive MZR@SPPP hydrogel system enables dual‐stage drug loading and sustained ocular delivery. Upon administration, it gelates at ocular surface temperature, enhancing ocular adhesion. By scavenging free radicals, restoring NRF2‐mediated antioxidant defense and mitochondrial homeostasis, and suppressing inflammatory ...

Effects of nitric oxide synthase inhibitor - Nitro-L-Arginine Methyl Ester, on silica-inducated inflammatory reaction and apoptosis [PDF]

, 2006
BACKGROUND: Although nitric oxide is overproduced by macrophages and neutrophils after exposure to silica, its role in silica-induced inflammatory reaction and apoptosis needs further clarification.

Endothelial nitric oxide synthase and estrogen [PDF]

Cardiovascular Research, 2000
See article by M.R. Andersen and S. Stender [1] (pages 192–199) in this issue. Andersen and Stender [1] have reported regional variations in endothelial nitric oxide synthase activity in the endothelial cells of the rabbit aorta. This paper adds an interesting new twist to the to link between atherosclerosis and e-NOS activity.

Self‐Adaptive Biomimetic Nanocomposite Hydrogel Orchestrates Dual‐Targeting and On‐Demand H2S Gasotransmission for Multifactorial Diabetic Wound Therapy

Advanced Science, EarlyView.
A self‐adaptive and biomimetic nanocomposite hydrogel is engineered to orchestrate dual‐targeting and on‐demand H2S gasotransmission for multifactorial diabetic wound therapy. By seamlessly integrating antibacterial, antioxidant, anti‐inflammatory, immunoregulatory, and pro‐angiogenic functions within a single platform, this hydrogel dynamically ...

Nitric oxide formation during cortical spreading depression is critical for rapid subsequent recovery of ionic homeostasis [PDF]

, 2003
NoCortical spreading depression (CSD) is a temporary disruption of local ionic homeostasis that propagates slowly across the cerebral cortex. Cortical spreading depression promotes lesion progression in experimental stroke, and may contribute to the ...

Precision Nanomedicine for Traumatic Neural Injury: Functional Paradigms and Translational Frameworks

Advanced Science, EarlyView.
This review presents a pathology‐driven framework unifying nanomedicine across TBI, SCI, and PNI. Epidemiological evidence and comparative single‐cell transcriptomic reanalysis define shared pathological modules, injury‐specific effectors, and therapeutic bottlenecks. Six functional paradigms connect nanomaterial structure and biological fate to injury‐

Tetrahydrobiopterin Protects Against Hypertrophic Heart Disease Independent of Myocardial Nitric Oxide Synthase Coupling

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundNitric oxide synthase uncoupling occurs under conditions of oxidative stress modifying the enzyme's function so it generates superoxide rather than nitric oxide.

Chrysanthemum Morifolium–Derived Nanovesicles Reduce Lactate‐Associated Histone Lactylation and Modulate Microglia‐Mediated Neuroinflammation in Sepsis‐Associated Encephalopathy

Advanced Science, EarlyView.
When used to treat sepsis‐associated encephalopathy, Chrysanthemum morifolium–derived nanovesicles can inhibit the H3K18la/NF‐κB axis to regulate microglia‐mediated neuroinflammation. ABSTRACT Sepsis‐associated encephalopathy (SAE)—a complication of the central nervous system in patients with sepsis—markedly diminishes cognitive functions and is linked
