Small Airways Dysfunction and Remission in Adults With Asthma: A Longitudinal Exploratory Analysis of the AssessmenT of smalL Airways involvemeNT In aSthma (ATLANTIS) Study

Allergy, EarlyView.
We conducted a post hoc analysis of ATLANTIS, a multinational prospective study including 684 adults with asthma. Fewer small airway symptoms and lower disease activity are independently associated with asthma remission. Replicated airway transcriptomic signatures show increased IL‐4/13 signalling and reduced coagulation pathways across the ATLANTIS ...

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

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.

Exhaled Volatile Organic Compounds Identify Allergic Patients Among Individuals With Chronic Rhinitis

Allergy, EarlyView.
Exhaled decane and nonadecane discriminate allergic (AR + LAR) from non‐allergic (NAR + HC) subjects among individuals with chronic rhinitis. LAR patients display higher levels of exhaled nonadecane than NAR individuals at baseline. Subjects with FeNO≥ 25 ppb have higher levels of exhaled decane, nonanal, and styrene than individuals with FeNO < 25 ppb

Nasal Airway Transcriptome Reflects Selected Asthma‐Associated Gene Signatures in the Lower Airways

Allergy, EarlyView.
Seven genes and two gene modules were consistently associated with asthma in both airway compartments in ARMS and were validated in ATLANTIS. The two modules reflected IL‐13 related inflammation and mast cell activity, respectively. Nasal gene signatures provide a non‐invasive proxy for selected bronchial asthma‐associated gene signatures. ARMS, Asthma

Balanço de nitrogênio, degradabilidade de aminoácidos e concentração de ácidos graxos voláteis no rúmen de ovinos alimentados com feno de Stylosanthes guianensis Nitrogen balance, amino acid degradability and volatile fatty acid concentration in the rumen of sheep fed Stylosanthes guianensis hay

Revista Brasileira de Zootecnia, 2002
Foram utilizados sete ovinos alimentados com feno de S. guianensis para avaliar a degradabilidade ruminal dos aminoácidos, o balanço nitrogenado e as concentrações de ácidos graxos voláteis (AGVs) no rúmen. A técnica de sacos de náilon foi empregada para

Assessing the suitability of Fractional Exhaled Nitric Oxide (FENO) cut-off ranges for aboriginal and/or Torres Strait Islander children and young adults

, 2018
Introduction/Aim Fractional exhaled nitric oxide (FeNO) is used as a non‐invasive measure of eosinophilic airway inflammation. It is unknown how appropriate the recommended FeNO cut‐off ranges are for Aboriginal and/or Torres Strait Islander patients ...

Oxidative Stress and Pteridines in Pediatric Asthma: Relationship to Exhaled Nitric Oxide

Pteridines, 2012
Fractional exhaled nitric oxide (FeNO) is a useful marker of airway inflammation in asthmatics. Nitric oxide synthase (NOS) requires tetrahydrobiopterin as a cofactor and produces superoxide during NO generation.
