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

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

Natural History of Alternaria Sensitisation and Association With Asthma and Rhinitis From Childhood to Adulthood

Allergy, EarlyView.
We aimed to characterise Alternaria sensitisation trajectories from childhood to adulthood; we compared SPT, whole‐extract sIgE and rAlt a 1, and assessed their longitudinal association with asthma and rhinitis in the Isle of Wight birth cohort. Alternaria sensitisation in the Isle of Wight Birth Cohort emerges mainly in late adolescence and, when ...

Serotonin Degradation and Lipid Metabolism Regulate Human Tc2 Cell Effector Functions

Allergy, EarlyView.
Human Tc2 cells exhibit a metabolically active phenotype characterized by enhanced glycolysis, mitochondrial respiration, and fatty acid uptake dependent on PPARγ. Alarmins strongly amplify IL‐5 and IL‐13 production in Tc2 cells, supporting a shared immunometabolic program across type 2 lymphocytes.

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

Deficiency of Mitochondrial Fatty Acid Enzyme, CPT1A, Underlies Airway Epithelial Barrier Dysfunction in Severe Asthma

Allergy, EarlyView.
Mitochondrial fatty acid enzyme, CPT1A, is deficient in the airway epithelium of severe asthma patients. Restoration of CPT1A expression improved epithelial barrier integrity via increasing mitochondrial respiration and ATP production in airway epithelial cells. Restoration of deficient epithelial CPT1A may represent a new treatment approach for severe

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.
