Age‐Dependent Correlation of Pulmonary Function Impairment and Aortic Arch Stiffness in Mice

open access: yesPediatric Discovery, EarlyView.
This study examined the relationship between aortic arch stiffness and lung function in aging mice. Multiple linear regression modeling showed moderate to strong correlations between the rise in aortic arch stiffness and changes in lung function as the mice progressively aged.

Oxygen Vacancies Modulation of Ammonium Tungsten Bronze by NH4+‐Assisted Heat Treatment for Highly Sensitive Detection of NO2

open access: yesRare Metals, EarlyView.
ABSTRACT Introducing oxygen vacancies has emerged as an essential strategy to affect the sensing properties of nanomaterials. However, existing methods for manipulating oxygen require high cost, complex operation, and harsh conditions. Herein, a simple NH4+‐assisted heat treatment approach was designed to regulate the concentration of oxygen vacancies ...

Classification of lung disease in HRCT scans using integral geometry measures and functional data analysis [PDF]

open access: yes, 2010
A framework for classification of chronic lung disease from high-resolution CT scans is presented. We use a set of features which measure the local morphology and topology of the 3D voxels within the lung parenchyma and apply functional data classification

Transanal minimally invasive surgery for rectal lesions [PDF]

open access: yes, 2016
Background and Objectives: Transanal minimally invasive surgery (TAMIS) has emerged as an alternative to transanal endoscopic microsurgery (TEM). The authors report their experience with TAMIS for the treatment of mid and high rectal tumors.

Identification of Clinically Distinct Clusters in Patients With Severe COPD Using Circulating Blood Cell Population Parameters

open access: yesRespirology, EarlyView.
This study investigated whether blood cell population data, in addition to cell counts, can identify clinically relevant COPD subgroups. Four distinct inflammatory profiles were identified with distinct clinical characteristics. Cell population data have the potential to provide additional insights beyond inflammatory cell counts and improve patient ...

Prevalence and Spirometric Transitions of PRISm and Obstruction: A Population‐Based Study

open access: yesRespirology, EarlyView.
ABSTRACT Background and Objective This study aims to assess the prevalence and longitudinal transitions of spirometric patterns defined by the lower limit of normal (LLN) criteria: normal airflow (FEV1/FVC≥LLN, FEV1 ≥ LLN); preserved ratio impaired spirometry (PRISm; FEV1/FVC≥LLN, FEV1 < LLN); or obstruction (FEV1/FVC

Emphysema predicts hospitalisation and incident airflow obstruction among older smokers: a prospective cohort study.

open access: yesPLoS ONE, 2014
BackgroundEmphysema on CT is common in older smokers. We hypothesised that emphysema on CT predicts acute episodes of care for chronic lower respiratory disease among older smokers.Materials and methodsParticipants in a lung cancer screening study age ...
