Toxicity Differences Between Microplastics and Nanoplastics in Organs: From Molecular Mechanisms to Potential Therapeutic Strategies

Med Research, EarlyView.
This review systematically compares the size‐dependent toxicity of microplastics and nanoplastics in the intestine, liver, kidney, lung, and brain. Particle size determines bioavailability, barrier penetration, and injury mechanisms. Because of their small size and high surface reactivity, NPs readily cross the intestinal epithelium and blood–brain ...

Glucocorticoids Impair the Airway Epithelial Barrier via Autophagy‐Associated Apoptosis in Asthma: A Preliminary Study Both In Vitro and In Vivo

Pediatric Discovery, EarlyView.
Mechanism underlying the negative effects of glucocorticoids on the airway epithelial barrier. Glucocorticoids upregulate autophagy factors and downregulate anti‐autophagy factors. Enhanced autophagy promotes excessive apoptosis and epithelial detachment, impairing airway barrier function.

LUNG FUNCTION TESTING IN CHILDREN

Zdravniški Vestnik, 2004
Background. Lung function testing in children above five years old is standardised similarly as is in adult population (1). Nevertheless bronchial provocation testing can be more hazardous since the calibre and reactivity of childhood airway is different.

Development and validation of a nomogram for predicting cough variant asthma diagnosis

BMC Pulmonary Medicine
Background Cough variant asthma (CVA) is a specific type of asthma characterized by chronic cough as the sole or predominant symptom. Accurate diagnosis is crucial for effective treatment, yet bronchial provocation test is not always feasible in clinical

Elevated fractional exhaled nitric oxide (FENO) in allergic asthmatics following bronchial allergen provocation.

, 2014
FENO was assessed in exhaled breath of asthmatics allergic to birch pollen (n = 13), before (light grey), 1 hour after (grey) and 24 hours after (dark grey) bronchial provocation with birch pollen. Bars indicate mean value of all individuals. Significant

Release of Mast Cell Tryptase into Saliva: A Tool to Diagnose Food Allergy by a Mucosal Challenge Test? [PDF]

, 2011
Background: Our aim was to examine whether measurement of the saliva mast cell tryptase (MCT) concentrations before and after a mucosal challenge test with the offending food would be helpful in diagnosing food allergy.

Optimizing and evaluation of a methacholine provocation test [Elektronisk resurs] : with application in occupational research

, 2002
We have developed a methacholine provocation method, which detects bronchial responsiveness in more than 80% of healthy subjects. The method enables us to detect differences in bronchial responsiveness within the normal range.
