This paper presents our more recent research on the area of text reading and understanding and knowledge extraction. More specifically, we give an overview of TextStorm and Clouds: two modules for the construction of concept maps. The first one deals with the task of extracting relations between concepts from a text file, while the latter concentrates on(More)
Uncovering the operating principles underlying cellular processes by using 'omics' data is often a difficult task due to the high-dimensionality of the solution space that spans all interactions among the bio-molecules under consideration. A rational way to overcome this problem is to use the topology of bio-molecular interaction networks in order to(More)
BACKGROUND The ankle-brachial index (ABI) is a noninvasive method to evaluate peripheral artery disease (PAD). ABI <0.9 diagnoses PAD; ABI >1.3 is a false negative caused by noncompressible arteries. The aim of this study is to evaluate the association between ABI with vascular calcifications (VC) and with mortality, in haemodialysis (HD) patients. (More)
Persistent high-risk human papillomavirus (HPV) infection is considered as the central cause of invasive cervical cancer. Specific HPV 16 and 18 sequence variations were associated with an increased risk for progression. The purpose of this study was to analyze intratypic variations of HPV 16 and 18 within the E6 gene, MY09/11 and LCR regions, and to(More)
In the yeast Saccharomyces cerevisiae, the presence of high levels of glucose leads to an array of down-regulatory effects known as glucose repression. This process is complex due to the presence of feedback loops and crosstalk between different pathways, complicating the use of intuitive approaches to analyze the system. We established a logical model of(More)
INTRODUCTION Obesity became a major public health problem as a result of its increasing prevalence worldwide. Paraoxonase-1 (PON1) is an esterase able to protect membranes and lipoproteins from oxidative modifications. At the PON1 gene, several polymorphisms in the promoter and coding regions have been identified. The aims of this study were i) to assess(More)
Congenital pulmonary airway malformation (CPAM) is a rare entity with potential for malignant transformation. We describe the case of a fourteen-year-old boy evaluated for the presence of a nodular image on the right lung on the chest x-ray. Computerized Tomography (CT) showed a round lesion of medium density with cavitation on the right lung. After one(More)
Persistent infection by high-risk human papillomavirus (HR-HPV) is a cause of cervical cancer. The use of HPV detection in cervical screening programs may improve the ability to identify women at risk of cervical cancer. Therefore, the development of appropriate methods for the detection of HR-HPV is essential. The aim of this study was to evaluate the(More)
The development of graphical user interfaces (GUIs) has been an emergent demand in the area of healthcare technologies. Specifically for respiratory healthcare there is a lack of tools to produce a complete multimedia database, where respiratory sounds and other clinical data are available in a single repository. This is essential for a complete patient's(More)
