Measurement of lung volumes by plethysmography [PDF]

European Respiratory Journal, 1997
There are various ways of measuring absolute lung volume. These range from measurements derived from chest radiographs to the more common laboratory measurements employing either gas dilution or plethysmography. The principal difference between the latter two methods is that gas dilution techniques measure gas that is in free communication with the ...

Obesity alters the fitness of peritumoral adipose tissue, exacerbating tumor invasiveness in renal cancer through the induction of ADAM12 and CYP1B1

Molecular Oncology, EarlyView.
Tumor microenvironment drives cancer formation and progression. We analyzed the role of human cancer‐associated adipocytes from patients with renal cell carcinoma (RCC) stratified as lean, overweight, or obese. RNA‐seq demonstrated that, among the most altered genes involved in the tumor–stroma crosstalk, are ADAM12 and CYP1B1, which were proven to be ...

Effect of yoga exercises on lung volumes, vital capacity, and attention span in school going students

Physiotherapy Quarterly
Objective The digital age has made children more dependent on digital sources for study and entertainment, which leads to increased physical inactivity that contributes to reduced work breathing and attention.

Repeatability of small lung nodule measurement in low-dose lung screening: a phantom study

BMC Medical Imaging, 2020
Background Lung cancer screening revealed that people with small pulmonary nodules are mostly asymptomatic and that some of these people are at risk of developing lung cancer, so we intended to explore the repeatability of small lung nodule measurement ...

Toward A Quantitative Understanding of Gas Exchange in the Lung [PDF]

arXiv, 2010
In this work we present a mathematical framework that quantifies the gas-exchange processes in the lung. The theory is based on the solution of the one-dimensional diffusion equation on a simplified model of lung septum. Gases dissolved into different compartments of the lung are all treated separately with physiologically important parameters.

CFA with preserved lung volumes [PDF]

Thorax, 1998
Doherty et al 1 seem confident of their ability to distinguish emphysematous spaces from large cystic spaces of honeycomb lung on the basis of a wall thickness on HRCT scanning of greater or less than 1 mm. In cryptogenic fibrosing alveolitis (CFA) we think this is difficult unless an assessment of function (with V/Q scanning or expiratory CT scans) is

Polyfunctional CD8+CD226+RUNX2hi effector T cells are diminished in advanced stages of chronic lymphocytic leukemia

Molecular Oncology, EarlyView.
CD226+CD8+ T cells express elevated levels of RUNX2, exhibit higher proliferation capacity, cytokines and cytolytic molecules expression, and migratory capacity. In contrast, CD226−CD8+ T cells display an exhausted phenotype associated with the increased expression of co‐inhibitory receptors and impaired effector functions.

Effects of preoperative inspiratory muscle training in obese women undergoing open bariatric surgery: respiratory muscle strength, lung volumes, and diaphragmatic excursion

Clinics, 2011
OBJECTIVE: To determine whether preoperative inspiratory muscle training is able to attenuate the impact of surgical trauma on the respiratory muscle strength, in the lung volumes, and diaphragmatic excursion in obese women undergoing open bariatric ...

3D Neural Network for Lung Cancer Risk Prediction on CT Volumes [PDF]

arXiv, 2020
With an estimated 160,000 deaths in 2018, lung cancer is the most common cause of cancer death in the United States. Lung cancer CT screening has been shown to reduce mortality by up to 40% and is now included in US screening guidelines. Reducing the high error rates in lung cancer screening is imperative because of the high clinical and financial ...
