Arrangement of Type IV Collagen on NH2 and COOH Functionalized Surfaces

Miranda Coelho, Nuno; González García, Cristina; Salmerón Sánchez, Manuel; Altankov, George (Wiley-Blackwell, 2011-07)

Apart from the paradigm that cell-biomaterials interaction depends on the adsorption of soluble adhesive proteins we anticipate that upon distinct conditions also other, less soluble ECM proteins such as collagens, associate ...
Assessment of non-invasive time and frequency atrial fibrillation organization markers with unipolar atrial electrograms

Alcaraz, Raúl; Hornero, Fernando; Rieta, J J (IOP Publishing: Hybrid Open Access, 2011-01)

The standard electrocardiogram (ECG) is the most common non-invasive way to study atrial fibrillation (AF). In this respect, previous works have shown that the surface lead V 1 reflects mainly the dominant atrial frequency ...
Automatic speech recognition in cocktail-party situations : a specific training for separated speech

Martí Guerola, Amparo; Cobos Serrano, Máximo; López Monfort, José Javier (Acoustical Society of America, 2012-02)

Automatic speech recognition (ASR) refers to the task of extracting a transcription of the linguistic content of an acoustical speech signal automatically. Despite several decades of research in this important area of ...
Chemotherapy-induced neutropenia does not correlate with DNA repair gene polymorphisms and treatment efficacy in advanced non-small-cell lung cancer patients

Sirera Pérez, Rafael (Elsevier, 2011-07)

[EN] Background: Platinum doublets are standard chemotherapy for advanced non-small-cell lung cancer (NSCLC). The aim of this study was to assess whether neutropenia is: (1) an indicator for treatment efficacy, or (2) ...
Circulating DNA is a useful prognostic factor in patients with advanced non-small cell lung cancer

Sirera Pérez, Rafael; Bremnes, Roy M.; Cabrera, Andrea; Jantus Lewintre, Eloisa; Sanmartin, Elena; Blasco, Ana; del Pozo, Nieves; Rosell, Rafael; Guijarro, Ricardo; Galbis, Jose; Sanchez, Jose Javier; Camps, Carlos (Lippincott, Williams & Wilkins, 2011-02)

Background: Circulating DNA is observed at higher concentrations in patients with lung cancer than in controls. Qualitative and quantitative analysis of circulating DNA is a promising noninvasive tool. Our aim was to ...
Classification of paroxysmal and persistent atrial fibrillation in ambulatory ECG recordings

Alcaraz, Raúl; Sandberg, Frida; Sornmo, Leif; Rieta Ibañez, José Joaquín (Institute of Electrical and Electronics Engineers (IEEE), 2011-05)

The problem of classifying short atrial fibrillatory segments in ambulatory ECG recordings as being either paroxysmal or persistent is addressed by investigating a robust approach to signal characterization. The method ...
