Abstract

The comparative approach takes advantage of the biological diversity to select the most appropriate model organism to tackle a scientific question. Comparisons between the endocrine and nervous systems accross species have yielded major breakthroughs in endocrinology and neurobiology. For instance: a number of mammalian peptide hormones and neuropeptides have been originally identified in fish or amphibians; studies conducted in a sea slug founded the cellular and molecular basis of learning and memory; observations of neurogenesis in the forebrain of songbirds led to the discovery of adult neurogenesis in the mammalian brain. These examples illustrate the remarkable contribution of the comparative approach for the advancement of neuroendocrinological concepts.The present e-book is a unique collection of research articles and reviews that provide a representative overview of the latest developments in comparative endocrinology and neurobiology.

Abstract

Sounding Islam provides a provocative account of the sonic dimensions of religion, combining perspectives from the anthropology of media and sound studies, as well as drawing on neo-phenomenological approaches to atmospheres. Using long-term ethnographic research on devotional Islam in Mauritius, Patrick Eisenlohr explores how the voice, as a site of divine manifestation, becomes refracted in media practices that have become integral parts of religious traditions. At the core of Eisenlohr’s concern is the interplay of voice, media, affect, and listeners’ religious experiences. Sounding Islam sheds new light on a key dimension of religion, the sonic incitement of sensations that are often difficult to translate into language.&#xD;

Abstract

L'inventaire des premières gravures italiennes regroupe plus de huit cents estampes exécutées au quattrocento et au début du cinquecento, toutes reproduites, à l'exception des doubles. Ce fonds exceptionnel – l'un des plus considérables avec ceux du British Museum et de l'Albertina – compte un grand nombre d'œuvres uniques ou rarissimes parmi lesquelles la plus ancienne gravure italienne connue, une épreuve de nielle (plaque d'orfèvrerie), datée de 1452. C'est sous cette forme que l'estampe apparaît en Italie, dans les ateliers d'orfèvres de Florence. Elle connaît une évolution rapide dans les cités artistiques : Florence, Ferrare, Mantoue, Milan, Venise, Vicence, Bologne, Rome. Technique de reproduction et de multiplication de l'image, ce nouveau média utilisé par des orfèvres, des miniaturistes, des peintres, des artisans, parfois de grands maîtres, tels Pollaiuolo et Mantegna, devient un moyen d'expression artistique autonome. Imprégnés de l'idéal esthétique de la Renaissance, les graveurs affirment leur créativité par les valeurs subtiles du noir et du blanc, la recherche de la beauté formelle, l'expressivité de la ligne, le jeu de l'ombre et de la lumière, le sens de l'espace dans la feuille. Leur production facilite la diffusion du langage visuel de la Renaissance et de l'iconographie, de la culture humaniste. Les thèmes profanes se multiplient. Les mythes classiques servent souvent des allégories moralisatrices philosophiques. Les figures fascinantes inspirées de l'antique (satyres, tritons et néréides, centaures, monstres marins), les grotesques et les statues romaines récemment découvertes, animent un univers surnaturel et fantastique, proche de notre sensibilité. Cet inventaire comporte une introduction illustrée – synthèse historique et artistique des débuts de l'estampe en Italie – suivie par l'historique détaillé du fonds du Cabinet des estampes. Les œuvres sont classées par école ou par graveur, chaque ensemble étant précédé d'un texte de présentation et d'une biographie de l'artiste, permettant au lecteur de les situer dans leur contexte. Les notices détaillées signalent l'historique des gravures et mentionnent les filigranes existants, tous reproduits, la plupart par bêtagraphie. On trouvera, à la fin, trois index (artistes, provenances et sujets).

Abstract

Para perceber em toda a sua complexidade como é que as grandes empresas portuguesas se relacionam com as grandes famílias que são suas proprietárias era necessário optar por urna metodologia etnográfica. O presente livro é exemplo de como um estudo intensivo de um número de casos relativamente pequeno, pode bem ser mais revelador do que estudos que, sendo mais abrangentes em termos numéricos, estão dependentes de modelos de interpretação menos intensivos. A elite que Maria Antónia Pedroso de Lima caracteriza corresponde ao contexto social de maior acumulação de riqueza a nível nacional português e até a nível internacional. Contudo, não poderíamos afirmar que se trata da elite portuguesa, já que a vida política e cultural portuguesa contemporânea é controlada por outros sectores sociais cuja radicação social nas classes medias profissionais é bem distinta da destas famílias empresariais. O relativo distanciamento destas famílias dos meios políticos e mediáticos nacionais posiciona-as numa espécie de marginalidade superior por relação aos contextos hegemónicos dominantes na sociedade portuguesa contemporânea.

Abstract

The gaseous molecule ethylene (C2H4), which is small in size and simple in structure, is a plant hormone most often associated with fruit ripening yet has a diversity of effects throughout the plant life cycle. While its agricultural effects were known even in ancient Egypt, the complexity of its mode of action and the broad spectrum of its effects and potential uses in plant physiology remain important scientific challenges today. In the last few decades, the biochemical pathway of ethylene production has been uncovered, ethylene perception and signaling have been molecularly dissected, ethylene-responsive transcription factors have been identified and numerous effects of ethylene have been described, ranging from water stress, development, senescence, reproduction plant-pathogen interactions, and of course, ripening. Thus ethylene is involved in plant development, in biotic and abiotic stress, and in reproduction. There is no stage in plant life that is not affected by ethylene, modulated by a complex and fascinating molecular machinery.

Abstract

Since the discovery of gonadotropin-releasing hormone (GnRH) at the beginning of 1970s, it has been believed that GnRH is the only hypothalamic neuropeptide that regulates gonadotropin release in vertebrates. In 2000, however, a novel hypothalamic neuropeptide that actively inhibits gonadotropin release was discovered in Japanese quail and termed gonadotropin-inhibitory hormone (GnIH). Following seventeen years of research has revealed that GnIH is highly conserved across vertebrates including humans, and GnIH is involved in a number of physiological and behavioral functions related to reproduction. The aim of this e-book is to celebrate the discovery of GnIH and the progress of GnIH research by collecting review and original articles from leading scientists in this new research field.

Abstract

Mammalian pregnancy represents a unique immunological riddle in that the mother does not reject her allogeneic fetus. In part this is largely due to a general sequestration or diminution of T cell activity, and an increased involvement of the innate immune system. The field of immunology is concerned primarily with how innate and adaptive mechanisms collaborate to protect vertebrates from infection. Although many cellular and molecular actors have evidently important roles, antibodies and lymphocytes are considered to be the principal players. Yet despite their importance, it would be definitely simplistic to conclude that they are solely essential for immunity overall. A major distinction between adaptive and innate immunity is the spontaneity of the innate immune response, which utilizes an already pre-existing but limited repertoire of responding modules. The slower onset of adaptive immunity compensates by its ability to recognize a much broader repertory of foreign substances, and also by its power to constantly improve during a response, whereas innate immunity remains relatively unaffected. The interactions between the reproductive system and the immune system are of particular interest, since the reproductive system is unique in that its primary role is to assure the continuity of the species, while the immune system provides internal protection and thus facilitates continued health and survival. The modus operandi of these two morphologically diffuse systems involves widely distributed chemical signals in response to environmental input, and both systems must interact for the normal functioning of each. Furthermore, dysregulation of normal physiological interactions between the reproductive and immune systems can lead to severe pregnancy-related disorders or complications. On the other hand, by ameliorating auto-inflammatory conditions such as MS and RA, pregnancy may provide a unique insight into novel immune modulatory strategies. The scientific focus on reproductive–immune research has historically provided substantial insight into the interface between these two physiological systems. A translational research approach would involve a tight interaction between diverse scientific and clinical disciplines including immunology, obstetrics, haematology, haemostasis and endocrinology. With so much recent progress in the field, we believe that it is valuable and well-timed to review the broad variety of the relevant physiologic and pathologic aspects – from menstruation to fertilization and implantation, and from placentation and pregnancy per se to the post partum condition - in which the immune system takes part. We are looking forward to a wide and vivid discussion of these and related issues, and we sincerely expect that our readers profoundly benefit from new exciting insights and fruitful collaborations.

Abstract

This book describes current knowledge about the mechanisms by which cells segregate their already duplicated chromosomes in preparation for cell division. Experts in the field treat several important aspects of this subject: (1) the history of research on mitotic mechanisms, to serve as a background; (2) assembly of the mitotic spindle; (3) Kinetochore assembly and function; (4) the mechanisms of chromosome congression to the metaphase plate; (5) the spindle assembly checkpoint; (6) mechanisms to avoid and correct erroneous chromosome attachments to the spindle; (7) a molecular perspective on spindle assembly in land plants; (8) chromosome segregation in anaphase A; (9) spindle elongation in anaphase B; and (10) the consequences of errors in chromosome segregation. Each chapter provides the reader with a comprehensive and accurate picture of current research in a form that is both readable and authoritative. The volume is suitable for scholars in this and related fields and for teaching at an advanced level.

Abstract

Plant reproduction is essential not only for producing offspring but also for increasing crop quality and yield. Moreover, plant reproduction entails complex growth and developmental processes, which provide a variety of opportunities for elucidating fundamental principles in biology. The combinational employment of molecular genetic approaches and emerging technologies, such as florescence-based imaging techniques and next generation sequencing, has led to important progresses in plant reproduction using model plants, crops, and trees. This e-book compiles 31 articles, including 1 hypothesis and theory, 4 perspectives, 12 reviews, and 14 original research papers. We hope that this E-book will draw attention of all plant biologists to exciting advances in the field of plant reproduction and help solve remaining challenging questions in the future. We wish to express our appreciation to all the authors, reviewers, and the Frontiers editorial office for their excellent contributions that made the publication of this e-book possible.
