The goal was to determine if inhaled nitric oxide (iNO) for 3 weeks during neonatal care of high-risk preterm infants was associated with improved pulmonary function and exercise capacity or altered exhaled nitric oxide (FeNO) levels in later childhood.
Obesity is characterized by abnormal adipose tissue expansion and is associated with chronic inflammation. Obesity itself may induce several comorbidities, including psychiatric disorders. It has been previously demonstrated that proinflammatory cytokines are able to up-regulate inducible nitric oxide synthase (iNOS) and nitric oxide (NO) release, which both have a role in compulsive related behaviors.
Current management of peripheral arterial disease involves risk factor modification and revascularisation, but many patients are still left with debilitating symptoms. Therefore, new treatment strategies are needed. The importance of nitric oxide, and its role in regulating endothelial function, is well-established. Altering the nitric oxide pathway has been extensively studied as a means of treating vascular disease, including peripheral arterial disease. Statins and ACE inhibitors have been shown to enhan...
Chronic heart failure is characterized by an inability of the heart to pump enough blood to meet the demands of the body, resulting in the hallmark symptom of exercise intolerance. Chronic underperfusion of the peripheral tissues and impaired nitric oxide bioavailability have been implicated as contributors to the decrease in exercise capacity in these patients. nitric oxide bioavailability has been identified as an important mediator of exercise tolerance in healthy individuals, but there are limited studi...
Patients with chronic kidney disease have an increased cardiovascular morbidity and mortality. It has been recognized that the traditional cardiovascular risk factors could only partially explain the increased cardiovascular morbidity and mortality in patients with chronic kidney disease. Asymmetric dimethylarginine (ADMA) and N-monomethy l-arginine (L-NMMA) are endogenous inhibitors of nitric oxide synthases that attenuate nitric oxide production and enhance reactive oxidative specie generation. Increased ...
Endogenous nitric oxide (NO) may contribute to ischemic and anesthetic preconditioning while exogenous NO protects against ischemia-reperfusion (I/R) injury in the heart and other organs. Why those beneficial effects observed in animal models do not always translate into clinical effectiveness remains unclear. To mitigate reperfusion damage a source of NO is required. NO inhalation is known to increase tissue NO metabolites, but little information exists about the lifetime of these species. We therefore sou...
To examine the association of polymorphism 4a/4b and 4b/4b in endothelial nitric oxide synthase gene (eNOS) with levels of natriuretic peptide type-C, endothelin-1 and vasoregulative endothelial function in patients with chronic heart failure (CHF) depending on the ejection fraction of the left ventricle.
[This corrects the article on p. 296 in vol. 9, PMID: 29593760.].
Nitric oxide (NO) has emerged as a critical molecule in wound healing, but the mechanism underlying its activity is not well defined. Here, we explored the effect of NO on the de-adhesion of epidermal stem cells (ESCs) and the mechanism involved in this process.
Diabetes is a downregulator of atrial natriuretic peptide (ANP), resulting in reduced nitric oxide level and low expression of endothelial nitric oxide synthase by which nitric oxide level get reduced. In the present study, we examined the role of ANP in reduced nitric oxide level, which may be responsible in controlling diabetic nephropathy in rats.
Nitric oxide is produced by enzymes called nitric oxide synthases. It fulfills many important functions in the human body, but produced in excess amount has a proinflammatory activity. Fractional exhaled nitric oxide measurements are used in the diagnosis and monitoring of eosinophilic inflammation in the lower airways, but should not be used as an independent parameter to make a diagnosis of asthma or for the monitoring of asthma treatment. Evaluation of fractional exhaled nitric oxide concentrations is al...
Chronic rhinosinusitis with nasal polyps (CRSwNP) is a significant health problem, but the pathogenesis remains unclear to date. Nitric oxide (NO) has known airway modulating functions. Therefore, we investigated nitric oxide production to determine the role of eNOS in nasal polyps, with additional analysis of the effect of the monoterpene oxide 1,8-cineol on the possible regulation of eNOS signaling and thus NO production.
Research increasingly suggests that nitric oxide (NO) plays a role in the pathogenesis of schizophrenia. One important line of evidence comes from genetic studies, which have repeatedly detected an association between the neuronal isoform of nitric oxide synthase (nNOS or NOS1) and schizophrenia. However, the pathogenetic pathways linking nNOS, NO, and the disorder remain poorly understood. A deficit in sensorimotor gating is considered to importantly contribute to core schizophrenia symptoms such as psycho...
Inducible nitric oxide synthase (iNOS) is a key regulator of the innate immune system. The aim of the current study was to explore whether innate immune-mediated iNOS and reactive nitrogen species acutely perturb acinar cell physiology and calcium homeostasis of exocrine salivary tissues.
In the past ten years, several chromosomal loci have been identified by genome-wide association studies to influence the risk of coronary artery disease (CAD) and its risk factors. The GUCY1A3 gene encoding the αsubunit of the soluble guanylyl cyclase (sGC) resides at one of these loci and has been strongly associated with blood pressure and CAD risk. More recently, further genes in the pathway encoding the endothelial nitric oxide synthase, the phosphodiesterases 3A and 5A, and the inositol 1,4,5-trisphos...
Endothelial nitric oxide synthase (eNOS) polymorphisms have been implicated as risk factors for erectile dysfunction (ED), but the results of genetic association studies are inconclusive. We performed a meta-analysis of published studies investigating the association between ED and three eNOS polymorphisms, intron 4 VNTR, G894T and T786C in humans.
There is a well-established association between chronic inflammation and an elevated risk of heart disease among patients with systemic autoimmune conditions. This review aims to summarize existing literature on the relationship between inflammatory bowel disease and ischemic heart disease, heart failure, arrhythmia, and pericarditis, with particular attention to approaches to management and treatment.
Cytoglobin is a widely expressed heme protein that binds oxygen, carbon monoxide and nitric oxide. Recent examination of cytoglobin in the vasculature indicates that it contributes to nitric oxide availability, which is central to normal blood vessel function through regulation of smooth muscle cell tone and physiological response. Given the potential implications of cytoglobin in vascular function, we examined how cytoglobin might be uniquely regulated in vascular smooth muscle cells. Our data demonstrate ...
Homeostasis around vascular endothelium is a function of the equilibrium between the bioavailability of nitric oxide (NO) and oxidizing reactive oxygen species (ROS). Within the vascular endothelium, NO enhances vasodilatation, reduces platelet aggression and adhesion (anti-thrombotic), prevents smooth muscle proliferation, inhibits adhesion of leukocytes and expression of pro-inflammatory cytokines genes (anti-inflammatory), and counters the oxidation of low density lipoprotein (LDL) cholesterol. A shift i...
Higher-energy Collision Dissociation for the quantification by liquid chromatography-tandem ion trap mass spectrometry of nitric oxide metabolites coming from S-nitrosoglutathione in an in vitro model of intestinal barrier.
The potency of S-nitrosoglutathione (GSNO) as a nitric oxide (NO) donor to treat cardiovascular diseases (CVDs) has been highlighted in numerous studies. In order to study its bioavailability after oral administration, which represents the most convenient route for the chronic treatment of CVDs, it is essential to develop an analytical method permitting (i) the simultaneous measurement of GSNO metabolites, i.e. nitrite, S-nitrosothiols (RSNOs) and nitrate and (ii) them to be distinguished from other sources...
Matrix metalloproteinase-9, Nitric oxide and inflammation plays a role in the pathogenesis of poly cystic ovary syndrome (PCOS). Even though these parameters are altered in PCOS, the effect of clomiphene citrate on them has not been studied till date. The present study was done to assess the effect of clomiphene citrate on matrix metalloproteinase-9, nitric oxide and interleukin-10 levels in women with PCOS.
Endothelial nitric oxide synthase (eNOS), and its product nitric oxide (NO), are vital components critical for the control of vasomotor function and cardiovascular homeostasis. In the present review, we will take a deep dive into eNOS enzymology, function and mechanisms regulating endothelial NO. The mechanisms regulating eNOS and NO synthesis discussed herein include alterations to transcriptional, post-translational modifications and protein-protein regulations. Moreover, we will discuss the phenotypes as...
Homocysteine (Hcy) is an independent risk factor for endothelial dysfunction in cardiovascular diseases. We hypothesized that the eNOS transcription enhancer AVE3085 may protect the endothelial function damaged by Hcy in the human internal mammary artery (IMA). Cumulative concentration-relaxation curves to acetylcholine (-10 to -4.5 log mol/L) or sodium nitroprusside were established in IMA from patients undergoing coronary artery surgery precontracted by U46619 (-8 log mol/L) in the absence/presence of Hcy...
