Ecología de las currucas mediterráneas en ambientes naturales y agrícolas del este de la península ibérica.

2018

RESUMEN En la presente tesis doctoral se investigan cuatro especies de currucas mediterráneas, la curruca capirotada (Sylvia atricapilla), curruca carrasqueña (S. cantillans), curruca cabecinegra (S. melanocephala) y curruca rabilarga (S. undata); concretamente se estudió su ecología en ambientes naturales y agrícolas del este de la Península Ibérica. En ella se describe la selección y preferencia de hábitat que realizan las especies, así como aspectos de su biología reproductiva. Los objetivos específicos van dirigidos a: 1) determinar la selección de hábitat realizada por las currucas durante su periodo reproductivo, y cómo es dicha selección con la presencia de especies congéneres en eco…

Simulating the impact of non-pharmaceutical interventions limiting transmission in COVID-19 epidemics using a membrane computing model

2021

Epidemics caused by microbial organisms are part of the natural phenomena of increasing biological complexity. The heterogeneity and constant variability of hosts, in terms of age, immunological status, family structure, lifestyle, work activities, social and leisure habits, daily division of time and other demographic characteristics make it extremely difficult to predict the evolution of epidemics. Such prediction is, however, critical for implementing intervention measures in due time and with appropriate intensity. General conclusions should be precluded, given that local parameters dominate the flow of local epidemics. Membrane computing models allows us to reproduce the objects (virus…

Novel hereditary angioedema linked with a heparan sulfate 3-O-sulfotransferase 6 gene mutation

2020

Background Hereditary angioedema (HAE) is a potentially fatal disorder resulting in recurrent attacks of severe swelling. It may be associated with a genetic deficiency of functional C1 inhibitor or with normal C1 inhibitor (HAEnCI). In families with HAEnCI, HAE-linked mutations in the F12, PLG, KNG1, ANGPT1, or MYOF genes have been identified. In many families with HAEnCI the genetic cause of the disease is currently unknown. Objective The aim of this study was to identify a novel disease-linked mutation for HAEnCI. Methods The study methods comprised whole exome sequencing, Sanger sequencing analysis, pedigree analysis, bioinformatic analysis of the mutation, and biochemical analysis of p…

A finite element-based machine learning approach for modeling the mechanical behavior of the breast tissues under compression in real-time

2017

[EN] This work presents a data-driven method to simulate, in real-time, the biomechanical behavior of the breast tissues in some image-guided interventions such as biopsies or radiotherapy dose delivery as well as to speed up multimodal registration algorithms. Ten real breasts were used for this work. Their deformation due to the displacement of two compression plates was simulated off-line using the finite element (FE) method. Three machine learning models were trained with the data from those simulations. Then, they were used to predict in real-time the deformation of the breast tissues during the compression. The models were a decision tree and two tree-based ensemble methods (extremely…

Hereditary angioedema with a mutation in the plasminogen gene

2017

Background Hereditary angioedema (HAE) with normal C1-INH (HAEnCI) may be linked to specific mutations in the coagulation factor 12 (FXII) gene (HAE-FXII) or functional mutations in other genes that are still unknown. We sought to identify and characterize a hitherto unknown type of HAE with normal C1-INH and without mutation in the F12 gene. Methods The study comprised analysis of whole-exome sequencing, Sanger sequencing, and clinical data of patients. Results We detected a mutation in the plasminogen (PLG) gene in patients with HAEnCI. The mutation c.9886A>G was located in exon 9 leading to the missense mutation p.Lys330Glu (K330E) in the kringle 3 domain of the PLG protein. The mutation…

Hereditary angioedema in a single family with specific mutations in both plasminogen and SERPING1 genes

2019

BACKGROUND Hereditary angioedema (HAE) is a group of genetic diseases characterized by recurrent, painful and potentially lethal tissue swelling. The most common form results from mutations in the SERPING1 gene, leading to reduced function of complement 1 inhibitor (C1-INH). Rarer forms with normal C1-INH may arise from mutations in the coagulation factor F12 gene, but mostly the genetic background is unknown. Recently, a novel HAE mutation in the plasminogen (PLG) gene was shown. PATIENTS AND METHODS We analyzed the various clinical manifestations of HAE in 14 related patients using clinical data, biochemical analysis for C1-INH and C4 as well as gene sequencing. RESULTS Patients' symptoms…

Treatment of skin swellings with C1-inhibitor concentrate in patients with hereditary angio-oedema.

2008

Background:  Skin swellings are the most frequent symptoms in hereditary angio-oedema (HAE) arising out of C1-inhibitor (C1-INH) deficiency. They may be painful and impact daily activities of patients. Detailed clinical data concerning the treatment of skin swellings by C1-INH concentrate have not been reported yet. Methods:  From 1976 through 2007, a total of 2104 skin-swelling attacks in 47 patients with HAE were treated with the C1-INH concentrate. Time to relief and duration of the swellings were documented during personal interviews using standardized questionnaires. The results were compared with 9046 untreated skin swellings in the same patients. Results:  The first clinical sign of …

Determinants of leisure-time physical activity and future intention to practice in Spanish college students

2009

Few studies analyze determinants and patterns of physical activity among college students, so it has not been possible to carry out effective interventions to promote this practice. The aim of this study was to analyze the associations between some personal, social, and environmental determinants, practice of physical activity and future intention to practice in a sample of 639 university students (321 men and 318 women), mean age 21.43 years (+/- 2.78). Physical fitness self-perception, physical activity history, and coach's support to practice physical activity have a direct effect on the practice of physical activity and an indirect effect on future intention to practice, both in men and…
