ABSTRACT The reproductive potential of red porgy in coastal waters of Buenos Aires Province (Argentina) and Uruguay (34º-39ºS) was studied by means of a macroscopic and histological analysis of the gonads. Length and age at first maturity were determined, and fecundity, spawning frequency and egg quality were estimated. The spawning season extended from spring through summer between October and January with a peak of spawning in December. Length and age at maturity for sexes combined was 24.5 cm...

Fisheries support livelihood of over half a billion of people globally. Many of these people live in coastal regions of developing countries; and have limited capacity to adapt and build resilience in the face of climate change.  This research assesses the biophysical and socioeconomic characteristics of fishers in four coastal communities, Komenda, Elmina, Cape coast and Morree, in Ghana. Structured questionnaire based on selected indicators that serve as proxy for components of the vulnerabili...

Abstract Background Endolithic microbes in coral skeletons are known to be a nutrient source for the coral host. In addition to aerobic endolithic algae and Cyanobacteria, which are usually described in the various corals and form a green layer beneath coral tissues, the anaerobic photoautotrophic green sulfur bacteria (GSB) Prosthecochloris is dominant in the skeleton of Isopora palifera. However, due to inherent challenges in studying anaerobic microbes in coral skeleton, the reason for its ni...

Abstract Background An estimated one third of energy is consumed in the workplace. The workplace is therefore an important context in which to reduce energy consumption to tackle the high rates of overweight and obesity in the general population. Altering environmental cues for food selection and consumption—physical micro-environment or ‘choice architecture’ interventions—has the potential to reduce energy intake. The first aim of this pilot trial is to estimate the potential impact upon energy...

Abstract Background Nutrition guidelines recommendations differ on the use of parenteral nutrition (PN), and existing clinical trial data are inconclusive. Our recent observational data show that amounts of energy/protein received early in the intensive care unit (ICU) affect patient mortality, particularly for inadequate nutrition intake in patients with body mass indices (BMIs) of <25 or >35. Thus, we hypothesized increased nutrition delivery via supplemental PN (SPN) + enteral nutrition (EN) ...

Abstract The solar quiet (Sq) source morphology changes on a daily basis and becomes disturbed during periods of increased magnetic activity. Therefore, it may be preferable to use single-day magnetic field recordings for the analysis of Sq variations. However, in short recordings, Sq and ocean tidal magnetic signals are often indistinguishable because of the close periods. As a result, the tidal magnetic signals can be erroneously attributed to signals of Sq origin, which can potentially lead t...

The early Paleogene is critical for understanding global biodiversity patterns in modern ecosystems. During this interval, Southern Hemisphere continents were largely characterized by isolation and faunal endemism following the breakup of Gondwana. Africa has been proposed as an important source area for the origin of several marine vertebrate groups but its Paleogene record is poorly sampled, especially from sub-Saharan Africa.

Au Canada, la navigation des patients atteints de cancer a vu le jour en Nouvelle-Écosse, en 2002, à l’instigation d’infirmières en oncologie ayant décidé de soutenir les patients du diagnostic au décès. La présente étude voulait déterminer la fréquence (et la variation de fréquence) des services de navigation et de contacts pour soins palliatifs chez les adultes décédés entre 2011 et 2014 après avoir reçu un diagnostic de cancer ainsi que des services de navigation. Parmi les 2 532 sujets de l’...

This paper is a short review on the biomonitoring of aquatic environments by animal and plant species accumulators of toxic pollutants ("scavengers"). This monitoring is based on the relationship between the pollutant concentration in the organism and that in its environment, and not on alterations produced by pollution on the biota. The latter is the basis of other types of biomonitoring, such as those based on the biotic and diversity indices and saprobic scale. The various aspects of monitori...

<p>Thermal alteration is one of the adverse effects of flow regulation sharpened in recent years due to climate changes. In this work, we characterize the thermal regime of a highly regulated river located in Northern Italy, which is the emissary of Lake Maggiore. The thermal characteristics of the study reach are influenced by the presence of two dams and by climate warming. In the 15-year monitored period (1999-2013) a significant increase of the mean annual river temperature (i.e., +1.8°C) wa...

Latin American countries have historically had a strong dependence on trade, and are mostly characterized by being exporters of raw materials and importers of manufactured products. This fact has brought about a less negative impact of the world crisis on economic growth, mainly because of the high prices of raw materials. This paper focuses on this geographical area (the West Coast of Latin America) between 2008 and 2015, and adds to the literature by assessing institutional, port-related and ...

En 2012, l’agence provinciale du cancer de l’Alberta lançait un projet d’amélioration de la qualité dans le but de créer, de mettre en œuvre et d’évaluer un programme provincial de navigation pour patients cancéreux englobant 15 établissements répartis sur plus de 600 000 kilomètres carrés. Ce projet a été sélectionné pour recevoir un financement de deux ans (d’avril 2012 à mars 2014) de l’Alberta Cancer Foundation (ACF), accordé à la suite d’un processus de subvention pour améliorer les soins (...

La navigation virtuelle (NV) dans le domaine des soins de santé est un processus proactif par lequel les patients obtiennent de l’information et du soutien grâce à des ressources sur Internet afin de gérer les exigences découlant de leur maladie. L’objectif de la présente analyse était d’explorer les points de vue convergents et divergents des principaux intervenants, c’est-à-dire les patients atteints de cancer et les fournisseurs de soins de santé (FSS), au sujet de l’outil de NV Oncology Inte...
