PVC Nanoplastics Exposure Exacerbates Asthma through R-Loop Accumulation and Subsequent STING Activation in Macrophages. [PDF]

open access: yesAdv Sci (Weinh)
Polyvinyl chloride (PVC) nanoplastics (NPs) are shown to aggravate allergic airway inflammation in asthma by triggering R‐loop accumulation and activating the cGAS‐STING pathway in macrophages. This study reveals a novel immunotoxic mechanism linking environmental plastic exposure to asthma pathogenesis and highlights potential molecular targets for ...

Pulmonary surfactant and prostaglandin E2 in airway smooth muscle relaxation of human and male guinea pigs. [PDF]

open access: yesPhysiol Rep
The relaxant effect of pulmonary surfactant on airway smooth muscle (Prostaglandin E2). Abstract Pulmonary surfactant serves as a barrier to respiratory epithelium but can also regulate airway smooth muscle (ASM) tone. Surfactant (SF) relaxes contracted ASM, similar to β2‐agonists, anticholinergics, nitric oxide, and prostanoids. The exact mechanism of

Etiologies and Treatment Outcomes of Chronic Cough Diagnosed with a Pathophysiological Diagnostic Procedure: A Single-center Retrospective Observational Cohort Study [PDF]

open access: yesThorac Res Pract
OBJECTIVE: We developed a pathophysiological diagnostic procedure to identify etiologies of chronic cough (CC) like cough variant asthma (CVA), atopic cough (AC), cough predominant asthma, sinobronchial syndrome (SBS), and mucoid impaction of small ...

Smooth Muscle Hypocontractility and Airway Normoresponsiveness in a Mouse Model of Pulmonary Allergic Inflammation

open access: yesFrontiers in Physiology, 2021
The contractility of airway smooth muscle (ASM) is labile. Although this feature can greatly modulate the degree of airway responsiveness in vivo, the extent by which ASM’s contractility is affected by pulmonary allergic inflammation has never been ...

Comparison of arterial storage conditions for delayed arterial ring testing

open access: yesJVS - Vascular Science, 2023
Objective: Arterial ring testing is the gold standard for measuring arterial function. Increased arterial tone through arterial contraction and impaired endothelial relaxation (endothelial dysfunction) are key metrics of impaired arterial health in ...

The effect of nose clip on exercise‐induced bronchoconstriction in adolescents

open access: yesPediatric Pulmonology, Volume 58, Issue 9, Page 2647-2655, September 2023., 2023
Abstract Background Oral breathing is considered to increase hyper‐responsiveness of the airways. Data on the need for nose clip (NC) during exercise challenge test (ECT) in children and adolescents is scarce. Ouraim was to evaluate the role of NC during ECT in children and adolescents.
