Abstract

ca. 200 words; this text will present the book in all promotional forms (e.g. flyers). Please describe the book in straightforward and consumer-friendly terms.[The World Health Organization (WHO) estimates that approximately one-third of worldwide infant deaths, and one half in developing countries, can be attributed to malnutrition. More specifically, iron (Fe) deficiency is the most common nutritional deficiency worldwide and a major cause of infant mortality. Fe deficiency is particularly widespread in low-income countries because of a general lack of consumption of animal products (which can promote non-heme Fe absorption and contain highly bioavailable heme Fe) coupled with a high consumption of a monotonous diet of cereal grains and legumes. Such diets are low in bioavailable Fe due to the presence of phytic acid and certain polyphenols that are inhibitors of Fe bioavailability. Diets with chronically poor Fe bioavailability which result in high prevalence of Fe deficiency and anemia, increase the risk of all-cause child mortalities and also may lead to many pathophysiological consequences including stunted growth, low birth weight, delayed mental development and motor functioning, among others. Thus, a crucial step in alleviating Fe deficiency anemia is through understanding how specific dietary practices and components contribute to the Fe status in a particular region where Fe deficiency is prevalent. The aim of this Special Issue is to report on the recent advances and research developments related to the improvements of dietary Fe bioavailability and absorption in an effort to alleviate dietary Fe deficiency.]

Abstract

The iron element (Fe) is strictly required for the survival of most forms of life, including bacteria, plants and humans. Fine-tuned regulatory mechanisms for Fe absorption, mobilization and recycling operate to maintain Fe homeostasis, the disruption of which leads to Fe overload or Fe depletion. Whereas the deleterious effect of Fe deficiency relies on reduced oxygen transport and diminished activity of Fe-dependent enzymes, the cytotoxicity induced by Fe overload is due to the ability of this metal to act as a pro-oxidant and catalyze the formation of highly reactive hydroxyl radicals via the Fenton chemistry. This results in unfettered oxidative stress generation that, by inducing protein, lipid and DNA oxidation, leads to Fe-mediated programmed cell death and organ dysfunction. Major and systemic Fe overloads occurring in hemochromatosis and Fe-loading anemias have been extensively studied. However, localized tissue Fe overload was recently associated to a variety of pathologies, such as infection, inflammation, cancer, cardiovascular and neurodegenerative disorders. In keeping with the existence of cross-regulatory interactions between Fe homeostasis and the pathophysiology of these diseases, further investigations on the mechanisms that provide cellular and systemic adaptation to tissue Fe overload are instrumental for future therapeutic approaches. Thus, we encourage our colleagues to submit original research papers, reviews, perspectives, methods and technology reports to contribute their findings to a current state of the art on a comprehensive overview of the importance of iron metabolism in pathophysiologic conditions.

Abstract

The 1/2<111> screw dislocations in bcc iron are studied by atomistic simulations. An analytical yield criterion captures correctly the non-Schmid plastic behavior. A model Peierls potential develops a link between the atomistic modeling at 0 K and the thermally activated dislocation motion. All predicted features agree well with experimental observations. This work establishes a consistent bottom-up model that provides an insight into the microscopic origins of the plastic behavior of bcc iron.

Abstract

Nowadays, the development of magnetic data storage devices technique faces fundamental limitations which lead to a slow-down of the increase of areal storage density. Therefore, magnetoelectric coupling which allows to change the magnetic state of matter by means of an electric field attracted significant interest. In this work, scanning tunneling microscopy was used to show for the first time that magnetic information can be written on the nanometer scale by the application of electric fields.

Abstract

Focusing on Western tourism behind the Iron Curtain, this chapter introduces the main research questions addressed in the volume: firstly, how and why Eastern Europe became a tourist destination for citizens of the West; secondly what impact this had on the development of a tourism industry in the Eastern bloc; and thirdly to what extent the experiences of Western tourists in Eastern Europe influenced mutual perceptions and Cold War stereotypes of “the other”. The chapter situates these questions in three debates in recent historiography: the history of transnational tourism, of the cultural Cold War, and of mobilities in the supposedly backward and static societies in Eastern Europe.

Abstract

Iron is an essential element for almost all organisms, a cofactor playing a crucial role in a number of vital functions, including oxygen transport, DNA synthesis, and respiration. However, its ability to exchange electrons renders excess iron potentially toxic, since it is capable of catalyzing the formation of highly poisonous free radicals. As a consequence, iron homeostasis is tightly controlled by sophisticated mechanisms that have been partially elucidated. Because of its biological importance, numerous disorders have been recently linked to the deregulation of iron homeostasis, which include not only the typical disorders of iron overload and deficiency but also cancer and neurodegenerative diseases. This leads iron metabolism to become an interesting therapeutic target for novel pharmacological treatments against these diseases. Several therapies are currently under development for hematological disorders, while other are being considered for different pathologies. The therapeutic targeting under study includes the hepcidin/ferroportin axis for the regulation of systemic iron homeostasis, complex cytosolic machineries for the regulation of the intracellular iron status and its association with oxidative damage, and reagents exploiting proteins of iron metabolism such as ferritin and transferrin receptor. A promising potential target is a recently described form of programmed cell death named ferroptosis, in which the role of iron is essential but not completely clarified. This Special Issue has the aim to summarize the state-of-the-art, and the latest findings published in the iron field, as well as to elucidate future directions.

Abstract

The International Institute of Applied Systems Analysis (IIASA), an international think tank established jointly by the United States and Soviet Union in Austria in 1972, was intended to advance scientific collaboration. Until the late 1980s, the IIASA was one of the very few permanent sites where policy scientists from both sides of the Iron Curtain could work together to articulate and solve world problems, most notably global climate change. One of the best-kept secrets of the Cold War, this think tank was a rare zone of freedom, communication, and negotiation, where leading Soviet scientists could try out their innovative ideas, benefit from access to Western literature, and develop social networks, thus paving the way for some of the key science and policy breakthroughs of the twentieth century.

Abstract

The interest in biocompatible and biodegradable metals, such as magnesium, is mainly related to their potential use as structural material for orthopedic and cardiovascular applications where a temporary medical device is required. However, in the case of magnesium, in vivo experiments have clearly shown that the corrosion degradation rate of magnesium and its alloys is too high and, hence, results in producing gas cavities that can promote the danger of gas embolism, tissue separation, and premature loss of mechanical integrity. The aim of this Special Issue on Biodegradable Metals is to explore and introduce innovative strategies to overcome the current limitations of magnesium.

Abstract

"The chapters of Fibula, Fabula, Fact – The Viking Age in Finland are intended to provide essential foundations for approaching the important topic of the Viking Age in Finland. These chapters are oriented to provide introductions to the sources, methods and perspectives of diverse disciplines in a way that is accessible to specialists from other fields, specialists from outside Finland, and also to non-specialist readers and students who may be more generally interested in the topic. Rather than detailed case studies, the contributors have sought to negotiate definitions of the Viking Age as a historical period in the cultural areas associated with modern-day Finland, and in areas associated with Finns, Karelians and other North Finnic linguistic-cultural groups more generally. Within the incredible diversity of data and disciplines represented here, the Viking Age tends to be distinguished by differentiating it from earlier and later periods, while the geographical space is quite fluidly defined for this era, which was long before the construction of modern nations with their fenced and guarded borders. Most significantly, the contributions lay emphasis on contextualizing the Viking Age within the complexities of defining cultural identities in the past through traces of cultural, linguistic or genetic features. The volume opens with a general introduction to the topic that is intended to provide a frame of reference for discussion, paralleled by a closing afterward. The following chapters are organized according to three thematic sections which reflect the three aspects of any discussion of the Viking Age in Finland: Time, Space, and People – because any discussion of the ‘Viking Age’ in ‘Finland’ is necessarily concerned with individuals, societies and cultures."
