Fishery-induced selection for slow somatic growth in European eel
2012
International audience; Both theoretical and experimental studies have shown that fishing mortality can induce adaptive responses in body growth rates of fishes in the opposite direction of natural selection. We compared body growth rates in European eel (Anguilla anguilla) from three Mediterranean stocks subject to different fishing pressure. Results are consistent with the hypotheses that i) fast-growing individuals are more likely to survive until sexual maturity than slow-growing ones under natural conditions (no fishing) and ii) fishing can select for slow-growing individuals by removing fast-growing ones. Although the possibility of human-induced evolution seems remote for a panmictic…
Reproductive monopoly enforced by sterile police workers in a queenless ant
2004
In societies of totipotent insects, dyadic dominance interactions generate a hierarchy that often underlies an extreme reproductive skew. Subordinates remain infertile but can maximize their indirect fitness benefits through collective power (worker policing): interference with challenging high-rankers can prevent an untimely replacement of the reproductive. However, police workers only benefit if they favor individuals with high fertility. In the monogynous queenless ant Streblognathus peetersi, we used behavioral, physiological, and chemical methods to show that police workers have the primary role in the selection of the reproductive, and that they probably use reliable information about…
Anakinra drug retention rate and predictive factors of long-term response in systemic juvenile idiopathic arthritis and adult onset still disease
2019
Background and Objective: Only a few studies have reported long-term efficacy of interleukin (IL)-1 inhibition in systemic juvenile idiopathic arthritis (sJIA) and adult-onset Still disease (AOSD). Herein we report on the effectiveness of anakinra (ANA), expressed in terms of drug retention rate (DRR), and evaluate the predictive factors of drug survival in a cohort of patients with sJIA and AOSD. Patients and Methods: This is a multicenter study reviewing retrospectively the medical records from 61 patients with sJIA and 76 with AOSD, all treated with ANA in 25 Italian tertiary referral centers. Results: The cumulative retention rate of ANA at 12-, 24-, 48-, and 60-month of follow-up was 7…
Drug Retention Rate and Predictive Factors of Drug Survival for Interleukin-1 Inhibitors in Systemic Juvenile Idiopathic Arthritis.
2019
Introduction: The advent of biologic agents has revolutionized therapeutic approaches in systemic juvenile idiopatic arthritis (sJIA) as their introduction has been shown to modify disease course and improve overall outcomes, particularly when initiated early. Few studies have reported the drug retention rate (DRR) of biologic drugs in JIA, and none of them has specifically investigated the DRR of interleukin (IL)-1 inhibitors on sJIA. Objectives: The primary aim of the study was to examine the overall DRR of IL-1 blockers in sJIA patients. Secondary aims of our study were to: (i) explore the influence of biologic line of treatment, adverse events (AEs), type of anti-IL-1 agent and the conc…
Diversity of extracellular vesicles from different developmental stages of Fasciola hepatica
2020
The secretion of extracellular vesicles (EVs) in Fasciola hepatica adult worms was described by our group in 2012. Since then, EVs have been found in other helminths, thus providing a new paradigm for the complete understanding of host-parasite communication. However, information was lacking regarding the possible existence and role of EVs from other developmental stages of the parasite. In this study, we confirm the secretion of EVs by F. hepatica eggs and juvenile forms. EVs were isolated by size exclusion chromatography and characterised by nanoparticle tracking analysis and electron microscopy. We observed a large diversity in the morphologies of these EVs, suggesting specific functions…
Delincuencia violenta, abuso y no consumo de drogas en adolescentes con riesgo de reincidencia
2020
espanolPresentamos un estudio original sobre consumo/abstinencia de drogas en adolescentes y su asociacion con el riesgo de reincidencia violenta. A una muestra de 192 sujetos se le aplico el cuestionario SAVRY –Structured Assessment of Violence Risk in Youth–, con el objetivo de analizar la asociacion entre el riesgo de reincidencia en delitos violentos y el consumo y abstinencia de drogas. Los resultados mostraron que: el no consumo se asocia al riesgo de reincidencia en delitos violentos intrafamiliares, el consumo de cocaina a robo con violencia e intimidacion, y el policonsumo de drogas al riesgo de reincidencia en diferentes delitos, siendo comun el ataque contra las personas. Las con…

Los contextos del uso de marihuana en Latinoamérica y culturas juveniles urbanas en México
2005
La intención de éste trabajo es dar cuenta de los contextos sociales, políticos y cultu¬rales de América Latina, especialmente el caso de México, con respecto a la situación de la producción y el consumo de la marihuana. Se trabaja la hipótesis teórica de que los contextos nos ayudan a comprender las distintas prácticas sociales con su diversi¬dad de sentidos y significados que generan los usuarios y los públicos consumidores de este bien no sólo material sino desde su valor simbólico teniendo como referente los movimientos sociales. Dentro de los públicos usuarios nos interesa enfatizar al sector de los jóvenes, es decir, a las culturas juveniles urbanas o a las adscripciones identitarias …
La educación sobre las drogas en la universidad: desde la mediación juvenil al compromiso de la comunidad universitaria
2004
Las drogas son hoy una cuestión esencial en el desarrollo de las sociedades modernas. Aunque el consumo de los diferentes tipos de drogas afecta a todas las capas poblacio¬nales, los jóvenes universitarios, por su futuro papel preponderante en la sociedad, preocupa de una manera especial, ya que ellos pueden liderar alternativas saludables y vitales. Hasta ahora han prevalecido las actitudes catastrofistas, las políticas prohibicionistas o cuando mucho las campañas meramente informativas. En este traba¬jo se presentan las drogas como tema de formación y prevención entre la población universitaria, analizándose las estrategias que puede ofrecer la universidad en sus dife¬rentes ámbitos y act…
