Controversy Total War

Total war is a controversial term used in the past by politicians, publicists and military officers as well as by computer specialists and academics in the present. Since its conception by French politicians during the First World War in a time of severe crisis (1916/17), it has become a term used by historians and other academics to cover a wide array of elements when looking at wars of the past. A real total war was and is impossible. Elements of total war – total war aims, total methods of warfare, total mobilization and total control – can, however, be identified and can serve as a useful tool for further transnational research on war.

Nationalism

What is nationalism? When did it originate and how did it develop throughout the centuries? What types of nationalism have evolved in different socio-political settings and why? By addressing these questions, this entry seeks to address the key issues of the conceptualization of nationalism, followed by an analysis of its development in different structural, cultural and political contexts. The entry reflects on the writings of the most prominent social thinkers studying nationalism in order to bring the classical texts into critical discussion with contemporary thinking about this phenomenon.

Bereavement and Complicated Grief across the Lifespan

Loss can be seen as a normative life event; nevertheless for most individuals, the experience of the loss of a loved one is extremely stressful. The grief reaction is universal but shaped by cultural norms and individual expectations; grief may also become a serious health problem. The aim of this article is to review the consequences of grief as well as explanations and treatment of complicated grief disorder. Five areas are identified to be of importance to clinicians and researchers: (1) grief reactions, (2) models of grief, (3) bereavement across the life span, (4) diagnostic criteria, and (5) treatment for complicated grief.

Common target genes of palatal and gingival fibroblasts for EMD: the microarray approach.

BACKGROUND AND OBJECTIVE Connective tissue grafts are frequently applied, together with Emdogain(®) , for root coverage. However, it is unknown whether fibroblasts from the gingiva and from the palate respond similarly to Emdogain. The aim of this study was therefore to evaluate the effect of Emdogain(®) on fibroblasts from palatal and gingival connective tissue using a genome-wide microarray approach. MATERIAL AND METHODS Human palatal and gingival fibroblasts were exposed to Emdogain(®) and RNA was subjected to microarray analysis followed by gene ontology screening with Database for Annotation, Visualization and Integrated Discovery functional annotation clustering, Kyoto Encyclopedia of Genes and Genomes pathway analysis and the Search Tool for the Retrieval of Interacting Genes/Proteins functional protein association network. Microarray results were confirmed by quantitative RT-PCR analysis. RESULTS The transcription levels of 106 genes were up-/down-regulated by at least five-fold in both gingival and palatal fibroblasts upon exposure to Emdogain(®) . Gene ontology screening assigned the respective genes into 118 biological processes, six cellular components, eight molecular functions and five pathways. Among the striking patterns observed were the changing expression of ligands targeting the transforming growth factor-beta and gp130 receptor family as well as the transition of mesenchymal epithelial cells. Moreover, Emdogain(®) caused changes in expression of receptors for chemokines, lipids and hormones, and for transcription factors such as SMAD3, peroxisome proliferator-activated receptor gamma and those of the ETS family. CONCLUSION The present data suggest that Emdogain(®) causes substantial alterations in gene expression, with similar patterns observed in palatal and gingival fibroblasts.
