The present work describes, for the first time, the changes that take place in the leaf apoplastic antioxidant defenses in response to NaCl stress in two pea (Pisum sativum) cultivars (cv Lincoln and cv Puget) showing different degrees of sensitivity to high NaCl concentrations. The results showed that only superoxide dismutase, and probably(More)
Massive amounts of acidic waters and mud (pH approximately 3) containing toxic metals such as zinc, lead, arsenic, copper, antimony, cobalt, thallium, bismuth, cadmium, silver, mercury and selenium were released in the surroundings of Doñana Park as a consequence of the mine tailings spill accident in Aznalcollar (SW Spain).

1. The booted eagle Hieraaetus pennatus is a poorly known and scarce raptor that breeds in Spain. In DonÄ ana National Park (south-west Spain) its population has increased from only six breeding pairs in the early 1980s to about 150 today. 2. In order to guide habitat management for this raptor in DonÄ ana National Park, we related nesting habitat selection(More)
Despite recovery plans, the Spanish Imperial Eagle (Aquila adalberti) and the Iberian lynx (Lynx pardinus) are in danger of extinction. These two flagship species tend to occur in pristine Mediterranean forests, and both prey preferentially on the rabbit (Oryctologus cuniculus). Spanish lynxes and eagles have sister species in continental Europe, the(More)
Heterologous expression in yeast has previously shown that the tomato cDNA LE-ACO1 encodes a functional 1-aminocyclopropane-1-carboxylate (ACC) oxidase (ACO) protein [Hamilton, A. J., Bouzayen, M. & Grierson, D. (1991) Proc. Natl Acad. Sci. USA 88, 7434-7437]. In the present work, full-length cDNAs encoding the two other members of the tomato ACO family(More)

A Hidden Markov Model (HMM) Toolbox within the Matlab environment is presented. In this toolbox, the conventional techniques for the continuous and discrete HMM are developed for the training as well as for the test phases. The ability to make different groups of components for the vector pattern is provided. Multilabeling techniques for the discrete HMM is(More)
BACKGROUND Despite best-possible medical management, many patients with end-stage cancer experience breathlessness, especially towards the end of their lives. We assessed the acceptability and effectiveness of non-invasive mechanical ventilation (NIV) versus oxygen therapy in decreasing dyspnoea and the amount of opiates needed. METHODS In this randomised(More)
Biomarkers are useful in community-acquired pneumonia (CAP). Recently, midregional (MR) proadrenomedullin (proADM) has been shown to be of potential prognostic use. We sought to determine whether this prognostic role depends on the cause of CAP. We conducted a prospective cohort study of immunocompetent patients with CAP. Pneumonia Severity Index (PSI) and(More)
—Over a period of 19 years, we studied 237 breeding attempts of Spanish Imperial Eagles (Aquila adalberti) in Doñana National Park (southwestern Spain), including 29 pairs with at least one immature member, to investigate age-related effects on population fecundity. Without considering effect of territory quality, adult pairs were signifi cantly more(More)
