Value of metalloproteinases in predicting COPD in heavy urban smokers

open access: yesRespiratory Research, 2020
Background Emphysema in asymptomatic heavy smokers can be detected during CT-scan screening for lung cancer. Metalloproteinases (MMPs) have been found to play a role in the pathogenesis of chronic obstructive pulmonary disease and to possibly serve as ...

Comorbid Conditions in Idiopathic Pulmonary Fibrosis: Recognition and Management. [PDF]

open access: yes, 2017
Idiopathic pulmonary fibrosis (IPF), a fibrosing interstitial pneumonia of unknown etiology, primarily affects older adults and leads to a progressive decline in lung function and quality of life.

Gorab deficiency in skin dermis accelerates aging and is associated with dysregulation of RCHY1‐mediated P53 ubiquitination

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Based on a dermis fibroblast Gorab knockout mouse model, this study revealed that Gorab deficiency promotes skin aging by influencing RCHY1, causing a decrease in P53 ubiquitination, damaging the activity of HDAC2, further resulting in the accumulation of aging‐related proteins (P53, P21, P16) and a reduction in extracellular matrix (ECM) components ...

Pulmonary Emphysema Regional Distribution and Extent Assessed by Chest Computed Tomography Is Associated With Pulmonary Function Impairment in Patients With COPD

open access: yesFrontiers in Medicine, 2021
Objective: This study aimed to evaluate how emphysema extent and its regional distribution quantified by chest CT are associated with clinical and functional severity in patients with chronic obstructive pulmonary disease (COPD).Methods/Design: Patients ...

Cannabis and the lung [PDF]

open access: yes, 2010
The use of cannabis is embedded within many societies, mostly used by the young and widely perceived to be safe. Increasing concern regarding the potential for cannabis to cause mental health effects has dominated cannabis research and the potential ...

Dr. Hans Kohn and the political takeover of the Berlin Medical Society by the National Socialist regime in 1933

open access: yesThe Anatomical Record, EarlyView.
Abstract To solidify their power over society, totalitarian regimes will usually eliminate any dissent, any perceived threats early on. These threats include not only political enemies but also educated and independent segments of society, such as professional associations.

Epidemiology, genetics, and subtyping of preserved ratio impaired spirometry (PRISm) in COPDGene. [PDF]

open access: yes, 2014
BackgroundPreserved Ratio Impaired Spirometry (PRISm), defined as a reduced FEV1 in the setting of a preserved FEV1/FVC ratio, is highly prevalent and is associated with increased respiratory symptoms, systemic inflammation, and mortality.

Three‐dimensional geometric morphometric analysis of diaphragmatic dome motion in COPD patients

open access: yesThe Anatomical Record, EarlyView.
Abstract Diaphragmatic dysfunction is a hallmark of chronic obstructive pulmonary disease (COPD), especially in emphysema, where hyperinflation alters diaphragm geometry and impairs inspiratory mechanics. However, quantitative three‐dimensional (3D) assessments of diaphragmatic dome shape and motion across COPD phenotypes are limited.

Autocrine insulin-like growth factor 2 signaling as a potential target in the associated development of pulmonary emphysema and cancer in smokers

open access: yesInflammation and Regeneration
Background Tobacco smoking causes pulmonary inflammation, resulting in emphysema, an independent risk factor for lung cancer. Induction of insulin-like growth factor 2 (IGF2) in response to lung injury by tobacco carcinogens, 4-(methylnitrosamino)-1-(3 ...
