T1WI‐SWI Dual Modal Magnetic Resonance Nanoprobes for Accurate Diagnosis of Early Stage Alzheimer's Disease

Advanced Science, EarlyView.
We developed a smart MRI nanoprobe targeting BACE1 and Aβ plaques. It crosses the blood‐brain barrier. Upon encountering BACE1, the probe is cleaved, enabling T1WI imaging detection. Subsequent reaction with ONOO− induces probe aggregation, enhancing magnetic susceptibility for sensitive SWI imaging of Aβ plaques.

Pichinde virus induces microvascular endothelial cell permeability through the production of nitric oxide

Virology Journal, 2009
This report is the first to demonstrate infection of human endothelial cells by Pichinde virus (PIC). PIC infection induces an upregulation of the inducible nitric oxide synthase gene; as well as an increase in detectable nitric oxide (NO).

Balanced Expression of the Diiron Oxygenase BioE Is Essential for Biotin Homeostasis in Elizabethkingia meningoseptica

Advanced Science, EarlyView.
BioE is a new diiron oxygenase that catalyzes the conversion of long‐chain acyl groups into pimeloyl thioester, initiating biotin synthesis. The overexpression of EmBioE disrupts lipid metabolic homeostasis, requiring repressor BioL to maintain a balance between long‐chain fatty acids and biotin synthesis.

Mechanism of the Protective Effect of Yulangsan Flavonoid on Myocardial Ischemia/Reperfusion Injury in Rats

Cellular Physiology and Biochemistry, 2014
Aims: Effect and mechanism of Yulangsan flavonoid (YLSF) on rat myocardial ischemia/reperfusion injury (MI/RI) has been investigated. Methods: Sprague-Dawley (SD) rats were randomly divided into seven groups (sham group, model group and NS group: 2 mL of

A nitric oxide synthase transgene ameliorates muscular dystrophy in mdx mice. [PDF]

, 2001
Dystrophin-deficient muscles experience large reductions in expression of nitric oxide synthase (NOS), which suggests that NO deficiency may influence the dystrophic pathology.

Targeting the SOX9/TIMP1 Axis with iRGD‐Conjugated Nanoplatform Enhances Dendritic Cell Function and Photodynamic Immunotherapy in Gastric Cancer

Advanced Science, EarlyView.
This study identifies the SOX9/TIMP1 axis as a key regulator of immune evasion in gastric cancer. iRGD‐conjugated nanoparticles co‐delivering si‐SOX9, Ce6, and L‐Arg are developed to synergize with photodynamic therapy. The nanoplatform suppresses tumor growth, promotes dendritic cell maturation, and enhances CD8+ T‐cell activation, offering a ...

Activation of hepatic acetyl-CoA carboxylase by S-nitrosylation in response to diet

Journal of Lipid Research
Nitric oxide (NO), produced primarily by nitric oxide synthase enzymes, is known to influence energy metabolism by stimulating fat uptake and oxidation. The effects of NO on de novo lipogenesis (DNL), however, are less clear.
