Identification of Female Cod (Gadus morhua) from Flemish Cap (Northwest Atlantic) at the Beginning of Ripening

18 páginas, 3 figuras, 6 tablas.-- Scientific Council MeetingOvaries of cod from Flemish Cap were sampled at three different times during the reproductive cycle. We study the use of the oocytes in the circumnuclear ring, cortical alveoli and vitellogenesis stages, the postovulatory follicles and gonosomatic index for the identification of females at the beginning of the ripening. The results obtained indicate that there is a period of less than two months between the end of spawning and the beginning of the development of the cortical alveoli stage, and more than three months to the beginning of vitellogenesis in all mature females. It is necessary to wait for these periods to use these structures to identify all the females at the beginning of ripening. Postovulatory follicles last a long time in the ovary, and their identification is possible seven months after spawning; the reconstruction of the last maturation ogive can be made three months after spawning. The mean gonosomatic index of mature and immature females showed significant differences three months after spawning, but the overlap between the maximum and minimum values impedes the use of this index to identify all females at the beginning of ripening.Peer reviewe

El trabajo decente en las cadenas mundiales de suministro

El trabajo ocupa una parte muy importante de la vida de las personas, permite que cubran sus necesidades y sentirse realizadas. Por ello se hace necesario que el ambiente y las condiciones en las que se realice sean los apropiados. Los avances en materia laboral de los últimos años para alcanzar estas metas, han conllevado al surgimiento del concepto de trabajo decente. En las grandes cadenas mundiales de suministro, se producen situaciones que ponen de manifiesto el incumplimiento de este concepto. Este trabajo trata de acercarse al ambiguo concepto del trabajo decente y relacionarlo con su cumplimiento en las grandes empresas españolas del sector textil, citando acuerdos que han adoptado para garantizarlo, así como, accidentes que se han producido en sus fábricas y que han puesto de manifiesto su incumplimiento.Grado en Relaciones Laborales y Recursos Humano

Dynamic Edematous Response of the Human Heart to Myocardial Infarction Implications for Assessing Myocardial Area at Risk and Salvage

BACKGROUND: Clinical protocols aimed to characterize the post-myocardial infarction (MI) heart by cardiac magnetic resonance (CMR) need to be standardized to take account of dynamic biological phenomena evolving early after the index ischemic event. Here, we evaluated the time course of edema reaction in patients with ST-segment-elevation MI by CMR and assessed its implications for myocardium-at-risk (MaR) quantification both in patients and in a large-animal model. METHODS: A total of 16 patients with anterior ST-segment-elevation MI successfully treated by primary angioplasty and 16 matched controls were prospectively recruited. In total, 94 clinical CMR examinations were performed: patients with ST-segment-elevation MI were serially scanned (within the first 3 hours after reperfusion and at 1, 4, 7, and 40 days), and controls were scanned only once. T2 relaxation time in the myocardium (T2 mapping) and the extent of edema on T2-weighted short-tau triple inversion-recovery (ie, CMR-MaR) were evaluated at all time points. In the experimental study, 20 pigs underwent 40-minute ischemia/reperfusion followed by serial CMR examinations at 120 minutes and 1, 4, and 7 days after reperfusion. Reference MaR was assessed by contrast-multidetector computed tomography during the index coronary occlusion. Generalized linear mixed models were used to take account of repeated measurements. RESULTS: In humans, T2 relaxation time in the ischemic myocardium declines significantly from early after reperfusion to 24 hours, and then increases up to day 4, reaching a plateau from which it decreases from day 7. Consequently, edema extent measured by T2-weighted short-tau triple inversion-recovery (CMR-MaR) varied with the timing of the CMR examination. These findings were confirmed in the experimental model by showing that only CMR-MaR values for day 4 and day 7 postreperfusion, coinciding with the deferred edema wave, were similar to values measured by reference contrast-multidetector computed tomography. CONCLUSIONS: Post-MI edema in patients follows a bimodal pattern that affects CMR estimates of MaR. Dynamic changes in post-ST-segment-elevation MI edema highlight the need for standardization of CMR timing to retrospectively delineate MaR and quantify myocardial salvage. According to the present clinical and experimental data, a time window between days 4 and 7 post-MI seems a good compromise solution for standardization. Further studies are needed to study the effect of other factors on these variables.This study was partially supported by a competitive grant from the Spanish Society of Cardiology (Proyectos de Investigacion Traslacional en Cardiologia de la Sociedad Espanola de Cardiologia 2015, for the project Caracterizacion tiSUlar miocaRdica con resonancia magnetica en pacientes tras inFarto agudo de mioCardio con elevacioN de ST sometidos a angloplastia Coronaria primaria.

Spawning process of the Yellowtail flounder (Limanda ferruginea)

11 páginas, 7 figuras, 3 tablas.-- Scientific Council MeetingThe spawning of Limanda ferruginea (Pleuronectidae) is analysed from 1892 mature females of 35 different samples. Batch fecundity is calculated using the "hydrated oocytes" method obtaining a value of 200.000+20.000 eggs. Hystological analysis of 103 ovaries showed the maturation process being continuous. Once a batch of eggs is spawned the next one is ending the nuclear migration. Based on the percentages of maturity stages found through the hours of the day and assuming hydratation process lasting the same that in other species (12 h), a daily spawning frequency is proposed for yellowtail flounder.Peer reviewe

Feeding Behaviour of the American Plaice (Hippoglossoides platessoides) on the Southern Grand Bank of Newfoundland

24 páginas, 14 figuras, 5 tablas.-- Scientific Council MeetingThis study shows that the diet of American plaice on the Southern Grand Bank, at sizes between 40 and 55cm, is mainly A.dubius and brittle stars, the third prey in importance is M. villonun To analyse feeding intensity during a daily and annual cycle, we used three different indices, the mean weight fullness index, the percentage of empty stomachs and the daily ration. The daily feeding intensity shows maxima related to the kind of prey eaten. A.dubius is consumed in larger amounts late in the day (18-24 hours), M.villosus and brittle stars are preyed upon more intensety'between 12 and 18 hours. Maximum feeding activity is in April, with a summer period of relatively high values, followed by autumn and winter when feeding intensity is low. The American plaice shows flexibility in its feeding behaviour, that allows it to consume its prey in larger amounts when they are more accessible; this accessibility may be the cause of its daily and annual feeding cycle.Peer reviewe

Determination of Fecundity in American Plaice (Hippoglossoides platessoides) and its Variation from 1987 to 1989

10 páginas, 2 figuras, 3 tablas.-- Scientific Council MeetingThe American plaice presents an oocyte development of the kind "group sychronous", with a fecundity determined in the beginning of its vitellogenesis (May). There are neither new recruitments of vitellogenic oocytes during the gonad development nor losses by atresic processes, which do not have a re ,julator importance over fecundity. The relative fecundity was very constant in 3N division, for the range of sizes analyzed, with a mean value of 409 eggs per gram of female weight, but there were changes in the somatic index, and for that reason in the length-fecundity relation. From these results some considerations are doing in relation to the vital strategy of this species.Peer reviewe
