BACKGROUND: Interferon-γ (IFN-γ) is conventionally regarded as an inflammatory cytokine that has a pivotal role in anti-infection and tumor immune surveillance. It has been used clinically to treat a variety of malignancies. However, increased evidence has suggested IFN-γ can act to induce tumor progression. The role of IFN-γ in regulating antitumor immunity appears to be complex and paradoxical. The mechanism underlying the dual aspects of IFN-γ function in antitumor immunity is not clear...

INTRODUCTION: There is no specific marker for lung cancer, but, in some lung cancer types, carcinoembryonic antigen (CEA) can reach high levels in the blood and pleural fluid. AIM: This study investigated the relationship of CEA levels in blood (CEAB) and intraoperative pleural lavage fluid (CEAP) in non-small-cell lung cancer (NSCLC) with the type, stage, and extent of lung cancer. MATERIAL AND METHODS: A total of 50 patients, who underwent surgery at our clinic due to NSCLC (group I) or benign lung pathology (group II), were assessed...

Here we report an in-silico approach for identification, characterization and validation of deleterious non-synonymous SNPs (nsSNPs) in the interleukin-8 gene using three steps. In first step, sequence homology-based genetic analysis of a set of 50 coding SNPs associated with 41 rsIDs using SIFT (Sorting Intolerant from Tolerant) and PROVEAN (Protein Variation Effect Analyzer) identified 23 nsSNPs to be putatively damaging/deleterious in at least one of the two tools used. Subsequently, structure-homology based PolyPhen-2 (Polymorphism Phenotyping) analysis predicted 9 of 23 nsSNPs (K4T, E31A, E31K, S41Y, I55N, P59L, P59S, L70P and V88D) to be damaging...

Asthma is a chronic allergic disease characterized by airway inflammation, airway hyper-responsiveness (AHR), and mucus hypersecretion. T-lymphocytes are involved in the pathogenesis of asthma, mediating airway inflammatory reactions by secreting cytokines. The phosphoinositide 3-kinase (PI3K) and Notch signaling pathways are associated with T cell signaling, proliferation, and differentiation, and are important in the progression of asthma. Thus, compounds that can modulate T cell proliferation and function may be of clinical value...

Lung cancer arises through the acquisition of a number of genetic lesions, with a preponderance of activating mutations in the canonical mitogen-activated protein kinase (MAPK) cascade (RTK-RAS-RAF-MEK). Braf(V600E) expression induces benign lung adenomas that fail to progress to adenocarcinoma because of oncogene-induced senescence (OIS). Braf(V600E) expression, coupled with simultaneous p53 ablation, permits bypass of senescence and progression to lung adenocarcinoma. However, spontaneous human tumors sustain mutations in a temporally separated manner...

Pulmonary hypertension due to lung diseases In 2015 the European Society of Cardiology and European Respiratory Society published new guidelines on the diagnosis and treatment of pulmonary hypertension (PH). PH due to lung diseases and/or hypoxia was classified as a separate entity. PH is common in lung diseases, but seldom severe. Nevertheless, the presence of PH in a patient with lung disease is associated with worse outcome. If there is clinical suspicion of PH in a patient with lung disease, echocardiography is recommended, and if there are signs of severe PH and/or severe right ventricular dysfunction the patient should be referred to a PH expert centre...

The prevalence of asthma and allergic diseases is disproportionately distributed among different populations, with an increasing trend observed in Western countries. Here we investigated how the environment affected genotype-phenotype association in a genetically homogeneous, but geographically separated population. We evaluated 18 single nucleotide polymorphisms (SNPs) corresponding to 8 genes (ADAM33, ALOX5, LT-α, LTC4S, NOS1, ORMDL3, TBXA2R and TNF-α), the lung function and five respiratory/allergic conditions (ever asthma, bronchitis, rhinitis, dermatitis and atopy) in two populations of Inuit residing either in the westernized environment of Denmark or in the rural area of Greenland...

INTRODUCTION: Glutathione-S-transferase (GST) P1 metabolises carcinogens from tobacco smoke in the lung. We tested whether genetically altered GSTP1 activity affects lung function and risk of tobacco-related cancer and mortality in the general population. METHODS: We genotyped 66,069 individuals from the Caucasian general population for two common, functional variants in the GSTP1 gene (Ile105Val and Ala114Val), and recorded lung function, lung cancer, tobacco-related cancer, and death as outcomes...

BACKGROUND: It has been proven that the circular RNA, possessing a stable covalently closed continuous loop, is a type of RNA molecule which is expressed widespread in mammals. The circular RNA circHIPK3 is abundantly expressed in hepatocellular carcinoma (HCC) and promotes tumourgenesis. However, a role for circHIPK3 has not been systematically examined in non-small cell lung cancer (NSCLC). In this study, we investigated whether circHIPK3 has an effect on cell proliferation in the NSCLC cell lines NCI-H1299 and NCI-H2170 and the underlying molecular mechanisms...

BACKGROUND: Pseudomonas spp are important opportunistic and nosocomial pathogens. One such species is Pseudomonas monteilii (P. monteilii). It has been described as an environmental contaminant and potential pathogen. We identified this organism as the causative agent of an exacerbation of bronchiectasis and an environmental contaminant in our hospital on two separate occasions. CASE PRESENTATION: P. monteilii was the cause of an exacerbation of bronchiectasis in a 30-year-old HIV negative male...

Profile signals of urine samples corresponding to patients with lung cancer and controls were obtained using a non-separative methodology. The method is based on the coupling of a headspace sampler, a programed temperature vaporizer and a mass spectrometer (HS-PTV-MS). With only a centrifugation step as prior sample treatment, the samples were subjected to the headspace generation process and the volatiles generated were introduced into the PTV where they were trapped in the Tenax® packed liner while the solvent was purged...

Clamshell (bilateral anterolateral thoracotomy combined to transverse sternotomy) is an invasive surgical approach that is helpful in particular situations, especially bilateral lung transplantation. The closure technique remains challenging because clamshell incision can end with override, separation, or sternal pseudarthrosis complications. We describe the use of new absorbable sternal pins to stabilize the sternal closure and to help avoid additional sternal complications.

BACKGROUND: The eighth tumor, node, metastasis (TNM) staging system (8-TNM) for non-small cell lung cancer (NSCLC) was newly released in 2015. This system had limitation because most patients included in the analysis were treated with surgery. Therefore, it might be difficult to reflect prognosis of patients treated with curative concurrent chemoradiotherapy (CCRT). Purpose of this study was to investigate clinical impact of the newly published 8-TNM compared to the current seventh TNM staging system (7-TNM) for locally advanced NSCLC patients treated with CCRT...

A new method is reported for fabrication of polymeric micro- and nanoparticles from an intermediate patterned surface originated by dewetting of a polymeric thin film. Poly (d, l-lactide-co-glycolide) or PLGA, a biocompatible polymer is used to develop a thin film over a clean glass substrate which dewets spontaneously in the micro-/nano-patterned surface of size range 50nm to 3.5µm. Since another water-soluble polymer, poly vinyl alcohol (PVA) is coated on the same glass substrate before PLGA thin film formation, developed micro-/nano-patterns are easily extracted in water in the form of micro- and nanoparticle mixture of size range 50nm to 3...

BACKGROUND: Recurrence rate after curative surgical resection of Hepatocellular carcinoma (HCC) remains high. Postoperative hepatic arterial infusion chemotherapy (HAIC) has been suggested to improve survival. This study is to investigate the efficacy of HAIC in the patients with poor tumor factors such as vascular invasion or multiplicity. METHODS: From 2006 to 2014, 221 patients with HCC undergoing hepatectomy and pathologically staged as ≧ T2 (American Joint Committee on Cancer TNM staging system, 7th edition) were included...

How sensory information influences the dynamics of rhythm generation varies across systems, and general principles for understanding this aspect of motor control are lacking. Determining the origin of respiratory rhythm generation is challenging because the mechanisms in a central circuit considered in isolation may be different than those in the intact organism. We analyze a closed-loop respiratory control model incorporating a central pattern generator (CPG), the Butera-Rinzel-Smith (BRS) model, together with lung mechanics, oxygen handling, and chemosensory components...

Lung cancer mortality remains high even after successful resection. Adjuvant treatment benefits stage II and III patients, but not stage I patients, and most studies fail to predict recurrence in stage I patients. Our study included 211 lung adenocarcinoma patients (stages I-IIIA; 81% stage I) who received curative resections at Taipei Veterans General Hospital between January 2001 and December 2012. We generated a prediction model using 153 samples, with validation using an additional 58 clinical outcome-blinded samples...

BACKGROUND: Massive pulmonary emboli can cause abrupt onset of symptoms simultaneous with large pulmonary artery occlusions. In contrast the temporal relationship between pulmonary vascular occlusion by smaller emboli and the development of pulmonary infarction symptoms is unknown. We describe the time interval between embolization and the onset of clinical symptoms and signs compatible with pulmonary infarction. METHODS: We examined the records of fifty six patients with Hereditary Hemorrhagic Telangiectasia (HHT) undergoing therapeutic balloon embolization of pulmonary arteriovenous malformations (PAVM's) in a single center after noting that some developed symptoms and signs compatible with pulmonary infarction...
