End-stage liver disease caused by the hepatitis C virus (HCV) is a major indication for liver transplantation. HCV re-infection after LT is constant, and it significantly impairs patient and graft survival. Factors that may influence histological recurrence in the graft remain unclear. The aim of our study is to analyse the factors that influence the(More)
During the last decade, gene expression microarrays and array-based comparative genomic hybridization (array-CGH) have unraveled the complexity of human tumor genomes more precisely and comprehensively than ever before. More recently, the simultaneous assessment of global changes in messenger RNA (mRNA) expression and in DNA copy number through "integrative(More)
Our project consists of designing and implementing an efficient general purpose web crawler. A web crawler is an automated program that accesses a web site and traverses through the site by following the links present on the pages systematically. The main purpose of web crawlers is to feed a data base with information from the web for later processing by a(More)
Relating a gene mutation to a phenotype is a common task in different disciplines such as protein biochemistry. In this endeavour, it is common to find false relationships arising from mutations introduced by cells that may be depurated using a phenotypic assay; yet, such phenotypic assays may introduce additional false relationships arising from(More)
BACKGROUND Vitamin D and vitamin D dependent antimicrobial peptides such as Cathelicidin (LL-37) and β-defensin 2 have an important role in innate and adaptative immunity, but their role in pleural effusions has not been studied before. METHODS Serum and pleural fluid samples from 152 patients with pleural effusion were collected, corresponding to 45(More)
