Leptospirosis is an emerging zoonotic disease caused by pathogenic species of the genus Leptospira. It has a broad range of clinical presentations in humans. Although progress has been made in the characterization of the host immune system factors that may affect disease progression and outcome, to date few reports have addressed the role of genetic(More)
OBJECTIVES Implantation of cell separation and mesenchymal stem cell culture techniques from human umbilical cord blood with and without using the Ficoll-Paque gradient density method (d=1.077 g/ml). METHODS Ten samples of the umbilical cord blood obtained from full-term deliveries were submitted to two different procedures of mesenchymal stem cell(More)
A method to compute the atherosclerotic plaque activity index (AI) was recently proposed in the literature to support the decision of endarterectomy. The dependency of this index on objective measures, extracted from Ultrasound and Clinical Data, aims at the increasing of the diagnosis accuracy by removing part of the subjective component associated with(More)
The aim of this study is to analyze the immediate and late evolution for death and reintervention in a thoracic endovascular aortic repair (TEVAR) group, over a follow-up period of 112 months. Retrospective data of 255 patients, from 1998 to 2007, were obtained. The most prevalent diseases were thoracic aortic aneurysms (89), thoracic and abdominal(More)
Wireless sensor networks (WSN) have been attracting growing interests for developing a new generation of large-scale embedded computing systems, with a great potential for a wide range of applications such as surveillance, environmental monitoring, emergency medical response or building automation. However, the communication paradigms in wireless sensor(More)
BACKGROUND The aim of this study was to assess by Doppler echocardiography (ECO) the functioning of the mitral valve apparatus in patients who have undergone implantation of standardized bovine pericardium chordae (SBPC) for replacement of ruptured or elongated chordae tendineae with significant thinning. METHODS SBPC were implanted in 31 patients who had(More)
Atrial fibrillation (AF) remains a frequent complication after coronary artery bypass graft surgery (CABG). We evaluate the association of AF occurrence and serum cardiac troponin I (cTnI) levels in the early postoperative period after CABG. Between April 2009 and January 2010, 95 consecutive patients with sinus rhythm who underwent CABG were evaluated. The(More)
OBJECTIVE To determine the immediate behavior and the prognostic value in terms of late survival of serum troponin I measurement in patients undergoing myocardial revascularization surgery with extracorporeal circulation. METHODS We studied 88 random patients, 65 (73.8%) of the male sex, who underwent myocardial revascularization surgery with(More)
There is a growing interest in integrating public transportation with the smartphone and mobile ticketing provides just that. To do so, different technologies can be used, such as Near Field Communication, Quick Response Codes and Bluetooth Low Energy. This paper explores the possibility of implementing a mobile ticketing solution, with focus on the ticket(More)
INTRODUCTION The conventional aortic valve replacement is the treatment of choice for symptomatic severe aortic stenosis. Transcatheter technique is a viable alternative with promising results for inoperable patients. Sutureless bioprostheses have shown benefits in high-risk patients, such as reduction of aortic clamping and cardiopulmonary bypass,(More)
