Differences in the uptake and metabolism of inhaled butadiene between rodents and primates, including people, might be reflected in differences in its toxicity. In order to compare uptake and metabolism in primates to that in rodents—for which data were already available—we exposed cynomolgus ...
Performing such measurements in an environment with zero aerosol background concentration levels is essential to ensure that every detected exhaled particle arises from respiratory activity, rather than from inhaled particle-laden air33. Vaccination, social distancing and other factors have reduced SARS-...
Kids and those with small frames and faces don’t match up well with adult-size gas masks. You must have a mask that fits properly, as poor fitment can compromise the seal between the mask and the face, rendering the mask useless in a hazardous environment....
39,40,41,42]. Notably, while epidemiological evidence supports associations between non-PM fractions of air pollution and adverse health outcomes [43,44,45], studies examining the effects of WS and DE typically utilize
Dual-source dual-energy computed tomography for evaluate inhaled drugs Figure 2 Methylene blue staining and dual-energy iodine imaging in rabbits illustrating the good relationship between the two methods. Iodine is indicated in red. The iodine overlay image is superimposed on a gray-scale mixed ...
The test consisted of exhaling as fully as possible, took a fast vital capacity breath, held their breath for 8 seconds, exhaled, and then repeated the fast vital capacity breath, again holding for 8 seconds. The patients inhaled the 35% CO2/65% O2 mixture or atmospheric compressed air, ...
21.1%, p = 0.02); the prescription rates of dual bronchodilators, inhaled corticosteroid/long-acting beta-agonist, and triple agents did not significantly differ between groups. According to the baseline moderate-to-severe exacerbation history in the previous year, both the occurrence rate and...
Introduction Analysis of exhaled breath condensate (EBC) is a noninvasive method to access the epithelial lining fluid of the lungs. Due to standardization problems the method has not entered clinical practice. The aim of the study was to assess the comp
The difference in annual FEV1 decline rate did not significantly differ either between CB patients and non-CB patients or between patients with severe CB and patients with mild CB. Conclusions CB patients had worse symptoms and lung function than non-CB patients; CB patients also had more ...
