The blood system transports nutrients, oxygen, carbon dioxide and nitrogenous wastes; other functions include defence. Fish have a closed, single circulation in which blood is pumped by a contractile heart via a ventral aorta to the gills, then via the dorsal aorta to vessels supplying the tissues and organs, with a venous return to the heart. Large venous sinuses occur in elasmobranchs. Air-breathing fish have modifications of the circulation. Complex networks of narrow blood vessels can occur as red patches, retia, maximizing transfer of nutrients, oxygen or heat. Most fish have nucleated red blood cells (erythrocytes) with haemoglobin. The types of white blood cells (leucocytes) are similar to those of other vertebrates but there are thrombocytes rather than platelets. Nutrient transport is in the plasma, the fluid component of the blood, which may also carry antifreeze agents and molecules (e.g. urea in elasmobranchs) which counteract deleterious osmotic effects

As a result of his classical training in the Honours School of Literæ Humaniores at Oxford, Oscar Wilde drew frequently on the works of Plato for inspiration, especially the Republic. The idea of a New Republic and its philosophy resonated profoundly with Wilde—so much so that the philosophical questions raised in Plato’s Republic become the central problems of The Picture of Dorian Gray. This chapter maps the parallels between the Republic and Dorian Gray, with specific focus on several of Plato’s most striking images from the Republic. In particular, the depiction of Lord Henry suggests not only the philosophical soul gone corrupt, but also the ‘drone’ who seduces the oligarchic young man into a life of ‘unprincipled freedom’, according to Plato’s definition of democracy. By invoking the Socratic lens, Wilde critiques Lord Henry’s anti-philosophy of the ‘New Hedonism’ and contrasts it with the Socratic eros.

The book’s subject is the widespread and formative reception of classical culture that takes place in childhood, with a specific focus on children’s pleasure reading in Britain and America from the mid-nineteenth to the mid-twentieth century. The production of literature designed to foster children’s connection to antiquity is identified as an adult project, which begins with the retelling of classical myths in the 1850s and which this study traces primarily in myth collections and works of historical fiction. Attention is also given to adults’ memories of their own childhood encounters with antiquity and the uses and meanings assigned to those encounters in memoirs and other works for adult readers.

The paper reflects on the experience of preparing a ‘From the Editors’ (FTE) editorial for The Academy of Management Review that went through a process of editorial evaluation prior to its rejection. It provides a detailed example of an encounter between orthodox and heterodox forms of scholarship, illuminating their distinctive value-orientations and forms of engagement. Its specific focus is upon evaluative criteria applied, accountability of decision-making and the mobilization of scholarly aspirations and ethical principles in the preparation and assessment of the FTE. Its intent is to stimulate debate on what it means to ‘challenge conventional wisdom’ – an aim that is broadly shared by ‘top’ journals in the field of management and organization.

AbstractThere is a high interest on gut health in poultry with special focus on consequences of the intestinal diseases, such as coccidiosis and C. perfringens-induced necrotic enteritis (NE). We developed a custom gene expression panel, which could provide a snapshot of gene expression variation under challenging conditions. Ileum gene expression studies were performed through high throughput reverse transcription quantitative real-time polymerase chain reaction. A deep review on the bibliography was done and genes related to intestinal health were selected for barrier function, immune response, oxidation, digestive hormones, nutrient transport, and metabolism. The panel was firstly tested by using a nutritional/Clostridium perfringens model of intestinal barrier failure (induced using commercial reused litter and wheat-based diets without exogenous supplementation of enzymes) and the consistency of results was evaluated by another experiment under a coccidiosis challenge (orally gavaged with a commercial coccidiosis vaccine, 90× vaccine dose). Growth traits and intestinal morphological analysis were performed to check the gut barrier failure occurrence. Results of ileum gene expression showed a higher expression in genes involved in barrier function and nutrient transport in chickens raised in healthy conditions, while genes involved in immune response presented higher expression in C.perfringens-challenged birds. On the other hand, the Eimeria challenge also altered the expression of genes related to barrier function and metabolism, and increased the expression of genes related to immune response and oxidative stress. The panel developed in the current study gives us an overview of genes and pathways involved in broiler response to pathogen challenge. It also allows us to deep into the study of differences in gene expression pattern and magnitude of responses under either a coccidial vaccine or a NE.
