Functional Lung Imaging Identifies Peripheral Ventilation Changes in ꞵ‐ENaC Mice

Respirology, Volume 30, Issue 4, Page 335-345, April 2025.
β‐ENaC‐Tg mice have previously been shown to exhibit muco‐obstructive disease and emphysema. This study analysed lung function in β‐ENaC‐Tg mice using XV functional imaging and flexiVent assessments. XV enabled ventilation defects to be identified and localised, and the flexiVent comfirmed increased lung compliance and reduced tissue elastance ...

Effects of some physical conditions on leaching rate of radon from radioactive minerals originating from some hot springs [PDF]

, 2007
In order to determine the best physical conditions for leaching more radon from minerals into water, we measured the leaching rate of radon from radioactive minerals under the conditions of some different grain sizes and water temperatures.

T1‐T2 Interplay in the Complex Immune Landscape of Severe Asthma

Immunological Reviews, Volume 330, Issue 1, March 2025.
ABSTRACT Asthma is orchestrated by an aberrant immune response involving a complex interplay between multiple inflammatory cell types. An increase in Th2 cells in the asthmatic airway is a hallmark of asthma, and biologics blocking their effector functions have been life‐changing for many severe asthma patients who poorly respond to immunosuppression ...

Improvement of glucocorticoid sensitivity and attenuation of pulmonary allergic reactions by exogenous supplementation with betaine in HDM and LPS‐induced allergic mouse model

Clinical and Translational Allergy, Volume 15, Issue 2, February 2025.
Abstract Background Childhood asthma is a heterogeneous disease that exhibits different characteristics and varying severity; however, the metabolite alterations underlying the difference in asthma severity, especially in severe asthma, are not well understood.

Deciphering and Predicting Microscale Controls on Radon Production in Soils, Sediments and Rock [PDF]

, 2018
Soils, sediments and rock are natural sources of radon (Rn), which poses an ongoing threat to human health. Numerous studies have measured Rn release from bulk earth materials, yet few have examined microscale controls on Rn flux from solids (emanation),

Differentiating Pulmonary Nodule Malignancy Using Exhaled Volatile Organic Compounds: A Prospective Observational Study

Cancer Medicine, Volume 14, Issue 1, January 2025.
ABSTRACT Background Advances in imaging technology have enhanced the detection of pulmonary nodules. However, determining malignancy often requires invasive procedures or repeated radiation exposure, underscoring the need for safer, noninvasive diagnostic alternatives.

Using Radiogenic Noble Gas Nuclides to Identify and Characterize Rock Fracturing

Earth and Space Science, Volume 12, Issue 1, January 2025.
Abstract Fracture‐released radiogenic noble gas nuclides are used to identify locations and constrain the volume of new fracture creation during subsurface detonations. Real‐time, in situ noble gases and reactive gases were monitored using a field‐deployed mass spectrometer and automated sampling system in a multilevel borehole array.
