New Nuclear SNP Markers Unravel the Genetic Structure and Effective Population Size of Albacore Tuna (Thunnus alalunga)

In the present study we have investigated the population genetic structure of albacore (Thunnus alalunga, Bonnaterre 1788) and assessed the loss of genetic diversity, likely due to overfishing, of albacore population in the North Atlantic Ocean. For this purpose, 1,331 individuals from 26 worldwide locations were analyzed by genotyping 75 novel nuclear SNPs. Our results indicated the existence of four genetically homogeneous populations delimited within the Mediterranean Sea, the Atlantic Ocean, the Indian Ocean and the Pacific Ocean. Current definition of stocks allows the sustainable management of albacore since no stock includes more than one genetic entity. In addition, short-and long-term effective population sizes were estimated for the North Atlantic Ocean albacore population, and results showed no historical decline for this population. Therefore, the genetic diversity and, consequently, the adaptive potential of this population have not been significantly affected by overfishing.

Hezkuntza Sozioekologikoa / Desazkunderako Hezkuntza

Egungo krisi sozioekologiko orokor eta sistemikoari irtenbidea emateko hezkuntza halabeharrezko elementua da. Egoera jasangaitzetik iraunkortasunera eramango gaituen trantsizio sozioekologikoan lanabes baliagarria izan daiteke hezkuntza eremu formal eta ez-formalean garatzen den ingurumen hezkuntza. Gizarte modernoetako botere ekonomiko eta politikoek hazkunde ekonomiko iraunkorraren mesederako erabili dute ingurumen hezkuntzaren oinarria den garapen iraunkorra. Desazkunde mugimenduak etengabeko hazkunde hori auzitan jarri du oinarri teoriko argiak erabiliz, eta oinarri teoriko horiek dira ikerlan honek ingurumen hezkuntzara ekarri nahi lituzkeenak. Proposamen horren egokitasuna baloratzeko, hezkuntza formalean garatu diren bi proiektu herritarren oinarriak aztertuko dira metodologia kualitatibo bidez.

Hizkuntza eskubideak estatuz gaineko Europan

Egungo Europa 50 estatu inguruk osatzen dute eta bertan 700 milioitik gora pertsonak hitz egiten dituzten 200 hizkuntza baino gehiago daude. Geografikoki eremu nahiko mugatua eta txikia izan arren, oso anitza ere badela esan dezakegu. Hizkuntza alorrean dagoen aniztasun horren gainean Europan egin den kudeaketa azaltzen ahaleginduko naiz lan honen bitartez, horretarako Europan azken hamarkadetan aintzatetsitako hizkuntza eskubideak, horien eraentza eta horien baitan emandako jurisprudentzia azalduz.

Estudios del efecto de la radiación ionizante sobre la permeabilidad de membranas modelo

La membrana biológica es una barrera hidrofóbica semipermeable de naturaleza compleja, cuya estructura consiste en una doble capa de moléculas de lípidos en la cual las proteínas están insertadas. Existen diferentes modelos para su estudio, uno de los cuales se basa en la utilización de membranas modelo. Por otra parte, la radioterapia es uno de los principales tratamientos para los distintos tipos de cáncer. En este trabajo se estudia el efecto de la radiación ionizante sobre la permeabilidad de membranas modelo, con objeto de comprender los mecanismos de su acción sobre dicho tratamiento.

Dietary animal and plant protein intakes and their associations with obesity and cardio-metabolic indicators in European adolescents: the HELENA cross-sectional study

Background: Previous studies suggest that dietary protein might play a beneficial role in combating obesity and its related chronic diseases. Total, animal and plant protein intakes and their associations with anthropometry and serum biomarkers in European adolescents using one standardised methodology across European countries are not well documented. Objectives: To evaluate total, animal and plant protein intakes in European adolescents stratified by gender and age, and to investigate their associations with cardio-metabolic indicators (anthropometry and biomarkers). Methods: The current analysis included 1804 randomly selected adolescents participating in the HELENA study (conducted in 2006-2007) aged 12.5-17.5 y (47% males) who completed two non-consecutive computerised 24-h dietary recalls. Associations between animal and plant protein intakes, and anthropometry and serum biomarkers were examined with General linear Model multivariate analysis. Results: Average total protein intake exceeded the recommendations of World Health Organization and European Food Safety Authority. Mean total protein intake was 96 g/d (59% derived from animal protein). Total, animal and plant protein intakes (g/d) were significantly lower in females than in males and total and plant protein intakes were lower in younger participants (12.5-14.9 y). Protein intake was significantly lower in underweight subjects and higher in obese ones; the direction of the relationship was reversed after adjustments for body weight (g/(kg.d)). The inverse association of plant protein intakes was stronger with BMI z-score and body fat percentage (BF%) compared to animal protein intakes. Additionally, BMI and BF% were positively associated with energy percentage of animal protein. Conclusions: This sample of European adolescents appeared to have adequate total protein intake. Our findings suggest that plant protein intakes may play a role in preventing obesity among European adolescents. Further longitudinal studies are needed to investigate the potential beneficial effects observed in this study in the prevention of obesity and related chronic diseases.

采用水平式淀粉胶电泳技术 ,对云南龙陵黄山羊、宁蒗黑头山羊、马关无角山羊和路南圭山羊等 4个保种山羊的 1 2 0个个体共 3 9个基因座位的基因多态性进行了研究。结果显示 ,云南 4个保种山羊品种在AKP、CES - 1、ESD、GOI、LAP、MDH、ME和NP基因座位出现多态。多态座位基因在不同保种山羊中分布不同。多态基因座位百分比 (P)在 4个保种山羊中分别为 0 .2 0 51 ,0 .1 53 8,0 .1 2 82和 0 .1 53 8。平均杂合度 (H)分别为 0 .0 95,0 .0 61 4 ,0 .0 4 67和 0 .0 662。用UPGMA法对由基因频率计算得到的Nei氏标准遗传距离进行聚类分析 ,结果表明云南保种山羊具地理分布及品种特点 ,龙陵黄山羊和其它 3个品种的遗传距离最远。

Cost and benefits of the Universal Basic Income implementation in Navarra

The Basic Income has been defined as a relatively small income that the public Administration unconditionally provides to all its members as a citizenship right. Its principal objective consists on guaranteeing the entire population with an income enough to satisfy living basic needs, but it could have other positive effects such as a more equally income redistribution or tax fraud fighting, as well as some drawbacks, like the labor supply disincentives. In this essay we present the argument in favor and against this policy and ultimately define how it could be financed according to the actual tax and social benefits’ system in Navarra. The research also approaches the main economic implications of the proposal, both in terms of static income redistribution and discusses other relevant dynamic uncertainties.
