Effect of Inhaled β2-Agonist on Exhaled Nitric Oxide in Chronic Obstructive Pulmonary Disease. [PDF]

PLoS ONE, 2016
The fractional exhaled nitric oxide measured at an expiratory flow of 50mL/s (FENO50) is a marker of airway inflammation, and high levels are associated with greater response to steroid treatment.

Betaine‐, xylitol‐, and extra virgin olive oil–based toothpaste modulates inflammation and oral nitric oxide pathway: Clinical trial in gingivitis

Journal of Periodontology, EarlyView.
Abstract Background Gingivitis is a prevalent and reversible inflammatory condition driven by microbial dysbiosis. Beyond plaque control, interest has grown in oral hygiene formulations capable of modulating inflammation while preserving key microbial functions. Extra virgin olive oil (EVOO), together with xylitol and betaine, has demonstrated clinical

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.

Nebulization of the acidified sodium nitrite formulation attenuates acute hypoxic pulmonary vasoconstriction

Respiratory Research, 2010
Background Generalized hypoxic pulmonary vasoconstriction (HPV) occurring during exposure to hypoxia is a detrimental process resulting in an increase in lung vascular resistance. Nebulization of sodium nitrite has been shown to inhibit HPV.

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Exhaled Nitric Oxide and Nitric Oxide Synthase Expression in Hodgkin's Disease [PDF]

International Journal of Immunopathology and Pharmacology, 2009
Hodgkin's disease (HD) is a malignant lymphoma with frequent mediastinal involvement, characterized by a significant inflammatory infiltration. Exhaled Nitric Oxide (F E NO), is present in healthy humans, and has been proven to be increased in eosinophilic diseases such as allergic asthma. We

Efficacy of Exhalation Delivery System With Fluticasone in Chronic Rhinosinusitis With Versus Without Polyps

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective To evaluate whether treatment responses to the exhalation delivery system with fluticasone (EDS‐FLU; XHANCE®) differ between patients with CRS with nasal polyps (CRSwNP) and patients without nasal polyps (CRSsNP). Study Design Post hoc analysis of the ReOpen clinical trials conducted between November 2018 and November 2021 for a 24 ...
