A Non-linear Diffeomorphic Framework for Prostate Multimodal Registration
2011
International audience; This paper presents a novel method for non-rigid registration of prostate multimodal images based on a nonlinear framework. The parametric estimation of the non-linear diffeomorphism between the 2D fixed and moving images has its basis in solving a set of non-linear equations of thin-plate splines. The regularized bending energy of the thin-plate splines along with the localization error of established correspondences is jointly minimized with the fixed and transformed image difference; where, the transformed image is represented by the set of non-linear equations defined over the moving image. The traditional thin-plate splines with established correspondences may p…
The Wnt-specific astacin proteinase HAS-7 restricts head organizer formation in Hydra
2021
Abstract Background The Hydra head organizer acts as a signaling center that initiates and maintains the primary body axis in steady state polyps and during budding or regeneration. Wnt/beta-Catenin signaling functions as a primary cue controlling this process, but how Wnt ligand activity is locally restricted at the protein level is poorly understood. Here we report a proteomic analysis of Hydra head tissue leading to the identification of an astacin family proteinase as a Wnt processing factor. Results Hydra astacin-7 (HAS-7) is expressed from gland cells as an apical-distal gradient in the body column, peaking close beneath the tentacle zone. HAS-7 siRNA knockdown abrogates HyWnt3 proteo…
Características que definen el fenómeno del botellón en universitarios y adolescentes
2007
Se presentan algunos de los principales parametros del patron de conducta de los jovenes cuando realizan botellon, intentando superar la vision poco precisa que han generado los estudios de campo. Se han recogido 4083 encuestas de jovenes entre 14-25 anos de la ciudad de Valencia, durante el curso academico 2005/2006 a partir de una muestra aleatoria de centros educativos, acudiendo a las aulas y solicitando la colaboracion anonima y voluntaria. Los resultados confirman la reduccion progresiva en la edad de inicio en la practica del botellon, situandose en 13 anos para los adolescentes que en estos momentos tienen 14 anos. Asimismo niegan que se trate de una practica mayoritaria entre varon…
The long-term use of psychiatric services within the Open Dialogue treatment system after first-episode psychosis
2017
AbstractOpen Dialogue is a family-oriented early intervention model for mental health problems developed in the health district of Western Lapland, Finland. In the present study, the aim was to describe how psychiatric services were used in Western Lapland after decades of first-episode psychosis services, and to analyze how baseline characteristics were related to re-admission rates and the total duration of psychiatric treatment in geographical area where Open Dialogue approaches were developed and efforts made to systematically apply them to all psychiatric treatments. The data were obtained from the medical histories of patients who had first-episode psychosis in 1992–2005 and who lived…

Research trends in the journal Hormones and Behavior (1987-2000).
2003
As a continuation of the study carried out by Svare more than 15 years ago (Horm. Behav. 22 (1988), 139) and to determine the tendencies of the evolution of behavioral endocrinology since then, our aim was to extend his work until 2000, assuming that the journal Hormones and Behavior would be representative of the field at large. To study this 14-year period and compare it with Svare's data, we kept the same criteria and categories, behavioral patterns, and species. Our results show that "sexual behavior" in "rodents" is still the most extensive field studied by behavioral endocrinologists, although frequency of other topics is increasing, above all "aggressive and emotional responses," and…
Asthma management in a specialist setting: Results of an Italian Respiratory Society survey.
2017
Abstract Background Asthma considerably impairs patients' quality of life and increases healthcare costs. Severity, morbidity, and degree of disease control are the major drivers of its clinical and economic impact. National scientific societies are required to monitor the application of international guidelines and to adopt strategies to improve disease control and better allocate resources. Aim to provide a detailed picture of the characteristics of asthma patients and modalities of asthma management by specialists in Italy and to develop recommendations for the daily management of asthma in a specialist setting. Method: A quantitative research program was implemented. Data were collected…

How pediatricians in Spain manage the first acute wheezing episode in an atopic infant. Results from the TRAP study.
2005
Abstract Background Although the treatment of asthma has been addressed in several guidelines, the management of the first acute wheezing episode in infants has not often been evaluated. We surveyed practicing pediatricians in Spain about the treatment they would provide in a simulated case. Material and methods A random sample of 3000 pediatricians and physicians who normally treated children was surveyed. The questionnaire inquired about how they would treat a first mild-to-moderate wheezing attack in a 5-month-old boy with a personal and family history of allergy. Pediatricians were asked about their professional background. Results A total of 2347 questionnaires were returned with usefu…
The International Study of Asthma and Allergies in Childhood (ISAAC) Phase Three: A global synthesis
2013
This ISAAC Phase Three synthesis provides summarised information on the main findings of the study, regional tables and figures related to the prevalence and severity of current symptoms of asthma, rhinoconjunctivitis and eczema in the main regions of the world. The large number of surveyed children (≈1,200,000), the large number of centres (233) and countries (98) that participated in ISAAC Phase Three makes this study the most comprehensive survey of these diseases ever undertaken. Globally, the prevalence for current asthma, rhinoconjunctivitis and eczema in the 13-14-year age group was 14.1%, 14.6% and 7.3%, respectively. In the 6-7-year age group the prevalence for current asthma, rhin…
