OBJECTIVE The aim of the study was to assess the diagnostic yield of the endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-NA) in the mediastinal staging in non-small cell lung cancer (NSCLC) patients. METHODS Consecutive NSCLC patients with enlarged or normal mediastinal nodes on CT scans underwent EBUS-NA. All patients with negative(More)
Interleukin (IL)-27 is a novel cytokine secreted by stimulated antigen-presenting cells. Initial studies on the biology of IL-27 provided evidence for its role in the initiation of T(H)1 responses; however, subsequent work has indicated that IL-27 has broad inhibitory effects on T(H)1, T(H)2, and T(H)17 subsets of T cells as well as the expansion of(More)
INTRODUCTION Free-circulating DNA is present in minute amounts in plasma of healthy individuals, whereas increased levels are found in a number of malignant pathologies including non-small cell lung cancer (NSCLC). The objective of this research was the evaluation of the plasma DNA quantification capacity to distinguish between healthy subjects and(More)
Alterations in the expression of growth factors and their receptors are associated with the growth and development of human tumors. One such growth factor is IGF-I (insulin-like growth factor I ), a 70-amino-acid polypeptide expressed in many tissues, including brain. IGF-I is also expressed at high levels in some nervous system-derived tumors, especially(More)
Aptamers are in vitro selected DNA or RNA molecules that are capable of binding a wide range of nucleic and non-nucleic acid molecules with high affinity and specificity. They have been conducted through the process known as SELEX (Systematic Evolution of Ligands by Exponential Enrichment). It serves to reach specificity and considerable affinity to target(More)
The exact role of FasL, and particularly its soluble and membrane-bound forms, in the development of chronic ILDs and lung fibrosis has not been extensively explored. We aimed at analyzing membrane-bound FasL expression on alveolar macrophages (AM) and lymphocytes (AL) as well as soluble FasL (sFasL) levels in bronchoalveolar lavage (BAL) from ILDs(More)
BACKGROUND AND PURPOSE The aim of the study was to estimate the usefulness of the antineoplastic vaccination in treatment of malignant brain tumors. According to medical knowledge there is no cure for this kind of tumors. MATERIAL AND METHODS Between 2001 and 2005, ten patients suffering from malignant glial tumors were treated. There were 5 male and 5(More)
Little is known about IGF-I expression in the alveolar lymphocytes (AL), and about local role of IGF-I in physiological conditions and in interstitial lung diseases. Bronchoalveolar lavage was carried out in patients with silicosis, asbestosis, idiopathic pulmonary fibrosis (IPF) and sarcoidosis, as well as in control subjects (n = 13, 9, 12, 56, 15, resp).(More)
