BACKGROUND: The main manifestations of radiation pneumonitis are injury of alveolar epithelial and endothelial cells, abnormal expression of cytokines, abnormal proliferation of fibroblasts and synthesis of fibrous matrix. The occurrence of radiation pneumonitis is associated with multiplecytokine level abnormality. These cytokines can also be used as bio-markers to predict the occurrence of radiation pneumonitis. This study was to evaluate the correlation between the change of apurinic/apyrimidinic endonuclease 1/redox factor-1 (Ape1/Ref-1), intercellular adhesion molecules 1 (ICAM-1) and interleukin-17A (IL-17A) before and after radiotherapy and radiation pneumonitis for local advanced non-small cell lung cancer (NSCLC) patients with concurrent chemoradiotherapy...

We have found that protocatechuic acid methyl ester (PCAME) attenuates fluoride (F- ) toxicity in lung epithelial cells (A549). However, these finding has to be confirmed with in vivo studies. Further, the effect of PCAME on F- induced pulmonary fibrosis and inflammation remains limited. Hence, the present study is aimed to determine the protective effect PCAME against F- induced pulmonary toxicity in female albino Wistar rats. The animals were treated with sodium fluoride (NaF, 300 ppm in drinking water ad libitum) alone or in combination with PCAME (25 or 50 mg/kg bw/day by oral intubation) for 60 days and analyzed for changes in lung histology, oxidative stress, inflammation, apoptosis and fibrosis markers...

Smoking is a significant risk factor in fatal pathologies including cardio-cerebrovascular and respiratory diseases. Aluminum (Al) is a toxic element without known biological function, but with recognized toxic effects. Manganese (Mn) and selenium (Se) are essential trace elements involved in cellular antioxidant defense mechanisms. Al, Mn, and Se carry out their metabolic activities via blood flow and tissue oxygenation. The structure and number of red blood cells (RBC) play important role in tissue oxygenation throughout blood flow...

BACKGROUND: Systemic sclerosis (SSc) is a major cause of pulmonary arterial hypertension (PAH). Murine models indicate key roles of chemokines CCL19/21 and their receptor CCR7 in lung inflammation leading to PAH. OBJECTIVE: We assessed the chemokine CCL19/21 axis in SSc-PAH. METHODS: Sera from two independent prospective SSc cohorts (n=326), idiopathic PAH (n=12) and controls (n=100) were analysed for CCL19/CCL21 by ELISA. Levels were defined as high or low using [mean + 2SD] in controls as cut-off...

Studies suggest elevated serum intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) levels may be markers of pulmonary arterial hypertension in systemic sclerosis (SSc-PAH). We sought to evaluate whether ICAM-1 and VCAM-1 levels are useful screening biomarkers for incident SSc-PAH. In this cross-sectional study, four groups were selected from the Australian Scleroderma Cohort Study: group 1 (n = 15) had definite PAH; group 2 (n = 19) had interstitial lung disease (ILD); group 3 (n = 30) were SSc-controls; and group 4 (n = 34) were healthy controls...

Sulfur mustard is a vesicant chemical warfare agent, which has been used during Iraq-Iran-war. Many veterans and civilians still suffer from long-term complications of sulfur mustard exposure, especially in their lung. Although the lung lesions of these patients are similar to Chronic Obstructive Pulmonary Disease (COPD), there are some differences due to different etiology and clinical care. Less is known on the molecular mechanism of sulfur mustard patients and specific treatment options. microRNAs are master regulators of many biological pathways and proofed to be stable surrogate markers in body fluids...
