Nitric oxide represses inhibitory κB kinase through S-nitrosylation
TLDR
It is demonstrated here that S-nitrosothiols (SNO) caused a dose-dependent inhibition of the enzymatic activity of IKK, in lung epithelial cells and in Jurkat T cells, which was associated with S- Nitrosylation of the IKK complex, providing an additional mechanism for its antiinflammatory properties.

Inhibition of Arginase Activity Enhances Inflammation in Mice with Allergic Airway Disease, in Association with Increases in Protein S-Nitrosylation and Tyrosine Nitration1
TLDR
In contrast to expectations, BEC enhanced perivascular and peribronchiolar lung inflammation, mucus metaplasia, NF-κB DNA binding, and mRNA expression of the NF-σκB-driven chemokine genes CCL20 and KC, and lead to further increases in airways hyperresponsiveness. Expand
In situ detection and visualization of S-nitrosylated proteins following chemical derivatization: identification of Ran GTPase as a target for S-nitrosylation.
TLDR
It is demonstrated that biotin derivatization is a useful approach to detect S-nitrosylated proteins in situ in cellular compartments or tissues, and will be useful in the assessment of altered S-Nitrosylation in pathological conditions. Expand
Electrochemistry of Caffeic Acid Aqueous Solutions with pH 2.0 to 8.5
The electrochemical behavior of caffeic acid (H3CAF) in aqueous solutions with pH 2.0 to 8.5 was studied by cyclic voltammetry, controlled potential electrolysis and UV-vis spectroscopy. TheExpand
Anti-inflammatory and antioxidant effects of Croton celtidifolius bark.
TLDR
It is demonstrated that Croton celtidifolius bark has significant anti-inflammatory and antioxidant activity. Expand
Serum Amyloid A Activates the NLRP3 Inflammasome and Promotes Th17 Allergic Asthma in Mice
TLDR
It is demonstrated that Saa3 is expressed in the lungs of mice exposed to several mixed Th2/Th17-polarizing allergic sensitization regimens, and administration of SAA to the lungs functions as an adjuvant to sensitize mice to inhaled OVA, resulting in leukocyte influx after Ag challenge and a predominance of IL-17 production from restimulated splenocytes that is dependent upon IL-1R signaling.

Study of antioxidant and mutagenic activity of different orange juices
The mutagenic effects of in natura and processed (fresh and frozen) orange juices were evaluated by the Salmonella /microsome assay (Ames Test). Antioxidant potential was determined by deoxyriboseExpand
In situ detection of S-glutathionylated proteins following glutaredoxin-1 catalyzed cysteine derivatization.
TLDR
The derivatization approach described here preferentially detects S-glutathionylation and provides an important means to visualize this post-translational modification in sub-cellular compartments and to investigate its relation to normal physiology as well as pathology. Expand
Antioxidant and anti-inflammatory effects of products from Croton celtidifolius Bailon on carrageenan-induced pleurisy in rats.
TLDR
Results show that C. celtidifolius contains substances with antioxidant and anti-inflammatory activity that, at least in part, act by a modulation of oxidative stress by phenolic compounds. Expand
Butanolic fraction from Cuphea carthagenensis Jacq McBride relaxes rat thoracic aorta through endothelium-dependent and endothelium-independent mechanisms.
TLDR
The data indicate that the BF of C. carthagenensis induces relaxation of the rat thoracic aorta by two mechanisms: an endothelium-dependent component of action, which clearly depends on the NO/cyclic guanosine monophosphate (cGMP) pathway and can be attributed, at least in part, to free radical-scavenging properties; and an endotchelium-independent component ofaction, which becomes evident at higher doses.
