Beyond Upper Airway Involvement: Evidence of Intrinsic Lung Disease in a Mouse Model of Mucopolysaccharidosis I

Journal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.
ABSTRACT Almost all patients with mucopolysaccharidosis (MPS) develop respiratory dysfunction of varying severity during disease progression. While respiratory disease in MPS has traditionally been attributed to upper airway obstruction caused by glycosaminoglycan (GAG) accumulation in the trachea and bronchi, involvement of the intrapulmonary ...

QUANTIFICATION OF BACK DIFFUSION IN RADON AND THORON EXHALATION RATE MEASUREMENTS

Radiation Protection Dosimetry, 2020
Abstract The radon (222Rn) and thoron (220Rn) fluxes from the soil and building materials are the major contributors to their indoor levels. Hence, the measurement of radon and thoron exhalation rates from the source matrix becomes the foremost step in controlling the indoor radon and thoron exposure.
