The Role of Iron‐Hyponitrite Intermediates in Biology and Insights From Synthetic Model Complexes

Chemistry – A European Journal, EarlyView.
Despite the difference in active site architecture, NO reduction by different NOR enzymes is expected to be linked by a common intermediate: hyponitrite (N2O22−). However, experimentally, very little is known about the coordination chemistry of iron with hyponitrite and the expected Fe‐hyponitrite intermediates.

Correlation between the FeNO Angle and d−p Mixing in {FeNO}⁷ Complexes

, 2016
The great majority of low-spin {FeNO}7 complexes exhibit FeNO angles of around 140−145°, whereas a small handful are characterized by linear FeNO units. Conspicuously absent are intermediate FeNO angles of 150−170°.

Corticosteroid Exposure in Chronic Rhinosinusitis and Global Airway Disease: Adrenal and Bone Impact

The Laryngoscope, EarlyView.
ABSTRACT Objective To investigate cumulative corticosteroid (CC) burden in patients with chronic rhinosinusitis with nasal polyps (CRSwNP), with or without coexisting asthma (global airway disease, GAD), referred for biologic treatment, and to assess the prevalence of CC‐related comorbidities, including secondary adrenal insufficiency, osteopenia and ...

Combination of Fractional Exhaled Nitric Oxide (FeNO) Level and Asthma Control Test (ACT) in Detecting GINA-Defined Asthma Control in Treated Asthmatic Patients in Vietnam

Canadian Respiratory Journal, 2020
Background. FeNO has been used as a marker for Th2-mediated airway inflammation in asthma. There is evidence which recommends the use of this biomarker in asthma management. Little is known about whether the FeNO test alone or in combination with the ACT

Small Airway Dysfunction Measured by Impulse Oscillometry and Fractional Exhaled Nitric Oxide Is Associated With Asthma Control in Children

Frontiers in Pediatrics, 2022
BackgroundImpulse oscillometry (IOS) and fractional exhaled nitric oxide (FeNO) are sensitive and non-invasive methods to measure airway resistance and inflammation, although there are limited population-based studies using IOS and FeNO to predict asthma

Contemporary Concise Review 2025: Asthma

Respirology, EarlyView.
ABSTRACT Asthma research in 2025 further advanced a multidimensional view of asthma, integrating disease trajectory, exacerbation risk, structural airway changes, comorbidities, and treatment responsiveness. In mild asthma, studies published in 2025 further reinforced the importance of anti‐inflammatory reliever strategies over SABA‐only treatment by ...

Contributions of asthma, rhinitis and IgE to exhaled nitric oxide in adolescents

ERJ Open Research, 2021
Exhaled nitric oxide fraction (FeNO) is an indicator of allergic airway inflammation. However, it is unknown how asthma, allergic rhinitis (AR) and allergic sensitisation relate to FeNO, particularly among adolescents and in overlapping conditions.

Sargassum Lung Syndrome: Air Flow Obstruction and Bronchial Inflammation Are Observed After Prolonged Exposure to Sargassum Gas Emissions in the Eastern Caribbean

Environmental Toxicology, EarlyView.
ABSTRACT Sargassum inundation of Caribbean and American shorelines is a growing environmental hazard. Hydrogen sulfide (H2S) and ammonia (NH3) produced by decomposing Sargassum could be involved in airway obstruction and bronchial inflammation. The study was undertaken to evaluate the effects of exposure to H2S and NH3 gases emitted during Sargassum ...
