background the attention of the scientific community has been recently focused on the role of tumor-infiltrating lymphocytes in non-small-cell cancer and there is a convergence of results, supporting a direct proportionality between lymphocytic infiltrate and good prognosis. objectives the aim of our research was to investigate the immune response around and inside the small-cell lung neoplasti...

The mechanical properties of lung tissue are important determinants of lung physiological functions. The connective tissue is composed mainly of cells and extracellular matrix, where collagen and elastic fibers are the main determinants of lung tissue mechanical properties. These fibers have essentially different elastic properties, form a continuous network along the lungs, and are responsible...

Non-invasive diagnosis of fetal lung immaturity. Ultrasound gray level histogram width (GLHW) tissue characterization was studied in fetal lung. GLHW ratio of fetal lung and liver was multiplied by gestational weeks, and fetal lung immaturity was diagnosed, if the product was less than 29. Ninety six per cent of neonatal respiratory distress syndrome (RDS) was predicted noninvasively in immatur...

Introduction: Planning target volume (PTV) is generated from internal treatment volume (ITV) using four-dimensional computed tomography (4D-CT) for enhanced therapeutic gain in the stereotactic body radiotherapy for lung lesions (SBRT-Lung). This study aimed to propose a strategy to generate ITV on multiple-phase 3D-CT and enhance therapeutic gain in SBRT-Lung. <stron...

UNLABELLED The expression of matrix metallo-proteinases (MMP-7 and MMP-9) and tissue inhibitors of metalloproteinases (TIMP-1 and TIMP-2), which are involved in the degradation of the extracellular matrix (ECM) and tumor growth, was investigated in normal lung tissue, tissue of benign pulmonary diseases and non-small cell lung cancer (NSCLC) tissue. PATIENTS AND METHODS Tumor tissue and surro...

background: broilers lung mechanisms that regulate endothelin (et) in the lung are complex and poorly understood. objectives: methods: in this experiment lung et-1 mrna levels and lung mrna expression for the et(a) receptors were determined in lung tissue weekly (term = 42 days, intervals = 7 days). serum endothelin concentration was also measured at these ages. results: the study showed that e...

Objective: In cardiovascular diseases, inflammatory response plays an important role and affects heart function. As a flavonoid compound, p-coumaric acid (pCA), commonly exists in many fruits and vegetables and has a therapeutic effect on inflammatory diseases due to its anti-inflammatory properties. The purpose of the present study was to investigate pCA anti-inflammatory effect and the miRNAs...

Concentrations of arsenic and selenium in lung, liver, and kidney tissue from dead smelter workers and from a control group have been determined with the aid of neutron activation analysis. A sevenfold increase of arsenic was found in lung tissue from the exposed workers compared with the control group. The median value of arsenic in lung tissue from workers dead from respiratory cancer was not...
