Pericytes and Smooth Muscle Cells Circulating in the Blood as Markers of Impaired Angiogenesis during Combined Metabolic Impairments and Lung Emphysema

The changes in endothelial progenitor cells and progenitor cells of angiogenesis, pericytes and smooth muscle cells, were studied in female C57BL/6 mice with a combination of metabolic impairments induced by injections of sodium glutamate and lung emphysema modeled by the administration of cigarette smoke extract. It was observed that sodium glutamate significantly enhances pathological changes in the lungs (inflammation and lung emphysema) induced by the administration of cigarette smoke extract. Recruiting of endothelial progenitor cells (CD45—CD31+CD34+ and CD31+CD34+CD146—) and progenitor cells of angiogenesis (CD45—CD117+CD309+) was registered in the injured lungs. Angiogenesis impairment induced by combined exposure is related to altered migration of pericytes (CD31—CD34—CD146+) and smooth muscle cells (CD31—CD34+CD146+) in emphysema-like enlarged lung tissue.

Publication date: Available online 13 February 2020Source: Pharmacology &TherapeuticsAuthor(s): Kylie B.R. Belchamber, Louise E. DonnellyAbstractChronic pulmonary conditions now account for 1 in 15 deaths in the US and mortality is increasing. Chronic obstructive pulmonary disease (COPD) is due to become the 3rd largest cause of mortality by 2030 and mortality from other respiratory conditions such as asthma, idiopathic pulmonary fibrosis and cystic fibrosis are not reducing. There is an urgent need for novel therapies to address this problem as many of the current strategies targeting inflammation are not sufficient. ...

ConclusionsThe use of a microwave surgical instrument for lung parenchymal dissection was associated with lower blood loss during surgery, reduced air leakage after surgery, and fewer postoperative complications.

ConclusionRadiological findings of particular interest included the high burden of opacities observed and the presence of RCS ‐associated features in the majority of subjects. Radiologists are at the front line in occupational lung disease screening/diagnosis and must be aware of the imaging spectrum.

α1-antitrypsin deficiency (AATD) is a hereditary disorder associated with a risk of developing liver disease and pulmonary emphysema, and other chronic respiratory disorders (mainly asthma and bronchiectasis); Z variant is the commonest deficient variant of AAT. Determining AAT concentration in serum or plasma and identifying allelic variants by phenotyping or genotyping are fundamental in the diagnosis of AATD. Initial evaluation and annual follow-up measurement of lung function, including post-bronchodilator forced expiratory volume in 1 s and gas transfer inform on disease progression. Lung densitometry is th...

Meanwhile, her lung function deteriorated with an obstructive pattern and therefore she was treated with inhalation medication without effect. Tests of the heart, bronchoscopy, gastroscopy and a CT-scan of the lungs did not reveal the cause. Finally, an FDG-PET scan showed inflammation of t...

Diagnosing potentially life-threating trachea injuries is usually troublesome as they are often part of a polytrauma scenario [1]. Symptoms related to this injury include pneumomediastinum, subcutaneous emphysema, respiratory difficulties, hoarseness, rattled breathing and haemoptoe. The purpose of the study was to analyze the role of bronchoscopy in patients where non-foreign body tracheal injury occurred.

ConclusionsSite of the resected lobe in lung cancer is not a prognostic factor of surgical mortality and morbidity in patients with IIPs. However, the impact of upper lobectomy on postoperative respiratory function reduction is larger than lower lobectomy in non-CPFE patients.

Abstract INTRODUCTION: Influenza vaccination is the most effective way to prevent influenza. Few studies on its rate were reported throughout China and for populations with chronic diseases. An estimation of the rates in China was accomplished. METHODS: All data were from a national cross-sectional survey of a sample representing the population aged 40 years or older in mainland China in 2014-15. A total of 74,484 individuals with complete self-reported influenza vaccination status were analyzed in 2018-19. RESULTS: The overall influenza vaccination rate was 2.4% (95% CI 1.4-3.3) with 1.7% (95% CI 1...
