BACKGROUND Most previous studies of the use of cervical pessaries were either retrospective or case controlled and their results showed that this intervention might be a preventive strategy for women at risk of preterm birth; no randomised controlled trials have been undertaken. We therefore undertook a randomised, controlled trial to investigate whether(More)
The aim of this article is focused on the design of an obstacle detection system for assisting visually impaired people. A dense disparity map is computed from the images of a stereo camera carried by the user. By using the dense disparity map, potential obstacles can be detected in 3D in indoor and outdoor scenarios. A ground plane estimation algorithm(More)

— This paper presents the introduction of Problem-Based learning (PBL) in a power electronics subject at the University of Oviedo (SPAIN) by means of two practical projects: the design and construction of a Switching-Mode Power Supply (SMPS) prototype and the static study of a dc-dc converter topology. The objective of this change in the traditional(More)
—The aim of the paper is focused on the design of an obstacle avoidance system for assisting visually impaired people. A disparity map will be generated thanks to the use of a stereo camera carried by the user. Working on this map will allow to develop an algorithm for the obstacle detection in any kind of scenario. The design will be completed with the(More)
BACKGROUND There is some evidence pointing toward better renal function in kidney transplant recipients (KTR) treated with once-daily tacrolimus (QD-TAC) vs. twice-daily tacrolimus (BID-TAC). METHODS This is an extension study of a 1-year, single arm prospective study of stable KTR who were converted from BID-TAC to QD-TAC (4.9 ± 4.0 years after(More)
Dysfunctional serotoninergic regulation and hypothalamic-pituitary-adrenal (HPA) axis overreactivity have been consistently reported in research studies with eating disorders (ED). In addition, the links between stress response, serotonin function, HPA axis and inflammatory mechanisms in ED have also been suggested in a number of studies. In our study,(More)
