Associations between nitric oxide synthase genes and exhaled NO-related phenotypes according to asthma status. [PDF]

PLoS ONE, 2012
BACKGROUND: The nitric oxide (NO) pathway is involved in asthma, and eosinophils participate in the regulation of the NO pool in pulmonary tissues. We investigated associations between single nucleotide polymorphisms (SNPs) of NO synthase genes (NOS) and

Covalently Immobilized Lignin–Xanthene Conjugates for Persistent Surface Photochemistry and Self‐Sterilizing Interfaces Under Ambient Visible Light

Macromolecular Rapid Communications, Volume 47, Issue 15, 4 August 2026.
Bio‐derived lignin–Eosin Y macromolecular networks are developed as visible‐light‐responsive self‐sterilizing coatings that generate reactive oxygen species without leaching. The spray‐coated photopolymerized surfaces exhibit durable antibacterial and antiviral activity under ambient light for extended periods, demonstrating a scalable and sustainable ...

Fractionated breath condensate sampling: H₂O₂ concentrations of the alveolar fraction may be related to asthma control in children

Respiratory Research, 2012
Background Asthma is a chronic inflammatory disease of the airways but recent studies have shown that alveoli are also subject to pathophysiological changes.

De novo or Salvage? Nucleotide Availability as a Driver of Bacterial Adaptation and Virulence

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Bacterial pathogens survive in different host environments by switching between making nucleotides by de novo synthesis and scavenging them from the host. This flexibility supports growth and virulence making nucleotide metabolism an attractive therapeutic target.

Exhaled breath condensate as matrix for toluene detection: a preliminary study.

, 2006
The study was designed to investigate whether exhaled breath condensate, obtained by cooling exhaled air in spontaneous breathing, could be a suitable matrix for toluene quantitative analyses. Nine healthy subjects were exposed for a short period (20 min)

Exhaled breath condensates and COPD [PDF]

European Respiratory Journal, 2009
To the Editors: Borrill et al. 1 have recently provided a timely review of exhaled breath condensates (EBC) in chronic obstructive pulmonary disease. However, there are several issues that deserve comment. Borrill et al. 1 argue that although it would be useful to use dilutional indicators for estimating the dilution of respiratory droplets from the ...

Exhaled Breath Condensates: Analyzing the Expiratory Plume [PDF]

American Journal of Respiratory and Critical Care Medicine, 2012
The mixture of gases and droplets released during exhalation can be hydrodynamically designated as a “plume.” Traditionally, pulmonologists focused on respiratory gases in these plumes, but recent identification of biomarkers in exhaled breath condensates (EBCs) has initiated vigorous efforts to harness this simple, noninvasive approach for diagnostic ...

Obstructive Sleep Apnea: Epidemiology, Pathophysiology, Complications, Diagnosis, Management, and Emerging Fibrosis‐Linked Remodeling

MedComm, Volume 7, Issue 8, August 2026.
Obstructive sleep apnea (OSA) is characterized by recurrent upper‐airway collapse, which generates key nocturnal stressors including intermittent hypoxia, sleep fragmentation, intrathoracic pressure stress, and sympathetic activation. These physiological disturbances converge on shared biological mechanisms, including oxidative stress, inflammation ...

Detection of pulmonary amylase activity in exhaled breath condensate

, 2013
Amylase activity in exhaled breath condensate (EBC) is usually interpreted as an indication of oropharyngeal contamination despite the fact that amylase can be found in pulmonary excretions.
