INTRODUCTION The functions of large noncoding RNAs (ncRNAs) have remained elusive in many cases. Metastasis-Associated-in-Lung-Adenocarcinoma-Transcript-1 (MALAT-1) is an ncRNA that is highly expressed in several tumor types. METHODS Overexpression and RNA interference (RNAi) approaches were used for the analysis of the biological functions of MALAT-1(More)
Recurrent respiratory papillomatosis (RRP) is a primary benign disease, which is characterized by papilloma-tous growth in the respiratory tract. Malignant transformation occurs in only 3-5% of cases, however, local growth of the benign papillomas is interpreted as clinically malignant in a markedly higher proportion of patients. Local surgical or(More)
Thymomas are tumors of thymic epithelial cells. They associate more often than any other human tumors with various autoimmune diseases; myasthenia gravis is the commonest, occurring in 10-50% of thymoma patients, depending on the World Health Organization-defined histologic subtype. Most thymomas generate many polyclonal maturing T lymphocytes but in(More)
OBJECTIVE The experience at our institution with various forms of lung transplantation (heart-lung, double lung and single lung) from December 1987 to September 1998 is reviewed and discussed. METHODS During this decade, 282 procedures (46 heart-lungs (HLTx), 142 double lungs (DLTx) and 94 single lungs (SLTx)) have been performed in 258 patients (140(More)
OBJECTIVE Patients with primary pulmonary hypertension (PPHT) have a worse natural outcome compared with those with secondary pulmonary hypertension in Eisenmenger's syndrome (ES) and chronic pulmonary embolism (CPE). Lung transplantation (SLTx, DLTx, HLTx) still remains the only therapeutical option for patients with this type of endstage lung disease. (More)
Acute renal failure (ARF) is a serious complication following cardiac surgery. This first controlled study was undertaken to verify, if Urodilatin (URO) infusion can revert incipient oliguric ARF after cardiac surgery. We conducted a randomized, double blind trial comparing 7 URO (20 ng/kg/min) with 7 placebo patients. Inclusion criterion was(More)
Comprehensive expression analysis using microarrays has identified a number of differentially expressed genes in smoke-exposed bronchial epithelium and non-small cell lung cancers (NSCLCs). To evaluate the prognostic relevance of these proteins in NSCLCs, we used immunohistochemistry to investigate the expression of beta-catenin (CTNNB1), dickkopf, Xenopus,(More)
OBJECTIVE Collateral artery growth or arteriogenesis is the primary means of the circulatory system to maintain blood flow in the face of major arterial occlusions. Arteriogenesis depends on activation of fibroblast growth factor (FGF) receptors, but relatively little is known about downstream mediators of FGF signaling. METHODS AND RESULTS We screened(More)
BACKGROUND  Major thoracic wall resections require the implantation of foreign materials for reconstruction and stabilization. Recently, biological collagen matrixes have emerged as an alternative to the routinely used synthetic materials. MATERIALS AND METHODS  Retrospectively, we analyzed our initial experience of chest wall reconstruction on large(More)
