Regulation of cardiac myocyte cell death.

Cardiac myocyte death, whether through necrotic or apoptotic mechanisms, is a contributing factor to many cardiac pathologies. Although necrosis and apoptosis are the widely accepted forms of cell death, they may utilize the same cell death machinery. The environment within the cell probably dictates the final outcome, producing a spectrum of response between the two extremes. This review examines the probable mechanisms involved in myocyte death. Caspases, the generally accepted executioners of apoptosis, are significant in executing cardiac myocyte death, but other proteases (e.g., calpains, cathepsins) also promote cell death, and these are discussed. The two principal cell death pathways (death receptor- and mitochondrial-mediated) are described in relation to the emerging structural information for the principal proteins, and they are discussed relative to current understanding of myocyte cell death mechanisms. Whereas the mitochondrial pathway is probably a significant factor in myocyte death in both acute and chronic phases of myocardial diseases, the death receptor pathway may prove significant in the longer term. The Bcl-2 family of proteins are key regulators of the mitochondrial death pathway. These proteins are described and their possible functions are discussed. The commitment to cell death is also influenced by protein kinase cascades that are activated in the cell. Whereas certain pathways are cytoprotective (e.g., phosphatidylinositol 3'-kinase), the roles of other kinases are less clear. Since myocyte death is implicated in a number of cardiac pathologies, attenuation of the death pathways may prove important in ameliorating such disease states, and possible therapeutic strategies are explored.

‘Rapt up with joy’: children’s emotional responses to death in early modern England

The chapter is an investigation of the child’s emotional response to death in early modern England. While much valuable scholarship has been produced on parents’ responses to the deaths of children, the reactions of the young themselves have rarely been explored. Drawing on a range of printed and archival sources, I argue that children expressed diverse and conflicting emotions, from fear and anxiety, to excitement and ecstasy. By exploring the emotional experiences of Protestants, the chapter contributes to the bourgeoning literature on emotion and religion, and contests earlier depictions of reformed Protestantism as an inherently intellectual, rather than an affective, faith. This study also suggests that we revise the way we classify the emotions, resisting the intuitive urge to categorise them as ‘positive’ or ‘negative’. The fear of hell, for example, though profoundly unpleasant, was regarded as a rational, commendable response, which demonstrated the work of the Holy Spirit in the soul, and was a prerequisite for the attainment of a joyful assurance of heaven. An underlying question is to what extent children’s responses to death differed from those of adults. I propose that although their reactions were broadly similar, the precise preoccupations of dying children were different. Through highlighting these distinctive features, we can come to a closer idea of what it was like to be a child in the early modern period.
