Abstract

Gottfried Dietrich Wilhelm Berthold (1854-1937) was one the foremost botanists and phycologists at the end of the 19th century. Born and educated in Westphalia, he enrolled at the Georgia Augusta to study plant sciences and focused on algae. After research stays at the Zoological Station at Naples he succeeded his mentor Johannes Reinke on his chair at the Institute of Plant Physiology at the Georgia Augusta Göttingen until 1923. In this study we focus on the biography of Berthold, his private and scientific life, interaction with J. Reinke and other topics related to the life of Berthold. In a second part we highlight his research on algae at the Gulf of Naples. We conclude with an evaluation of his scientific work in the light of the different phases in his life including a full bibliography of his scientific publications. Our study contributes to history of science at the Georgia Augusta.

Der aus Westfalen stammende Gottfried Dietrich Wilhelm Berthold (1854- 1937) ist als Botaniker des 19. und beginnenden 20. Jahrhunderts eng mit der Geschichte der Georgia Augusta in Göttingen verwoben. Er hatte sich bereits als Student an der Universität Göttingen mit Algen beschäftigt und seine Dissertation dieser Thematik gewidmet. Nach Forschungsaufenthalten an der Zoologischen Station in Neapel, wo er intensiv Untersuchungen an Algen durchführte, habilitierte er sich 1881 in Göttingen bei Johannes Reinke. Später übernahm er dessen Professur für Botanik sowie dessen Direktorat am Pflanzenphysiologischen Institut und widmete sich entwicklungsmechanischen bzw. physiologischen Fragen bei höheren Pflanzen. Die vorliegende Monografie untersucht erstmalig anhand der gegenwärtigen Forschungslage Leben und Wirken Bertholds. Bertholds Lebensgeschichte wird chronologisch und in größtmöglicher Vollständigkeit dargestellt. Bildungsgeschichtliche Akzente, der personelle Konnex zu Johannes Reinke und der Einfluss der Zoologischen Station Neapel finden hier ebenso Platz wie die Rekonstruktion der Lehr- und Forschungstätigkeiten und der familiären Verhältnisse. Da Berthold vorrangig als Phykologe, also Algenkundler anzusehen ist, widmet sich der zweite Teil dem Forschungsschwerpunkt Algen. Dabei werden vor allem die meeresbiologischen Aspekte seiner Forschung am Golf von Neapel untersucht. Bertholds unterschiedliche Lebensstationen können in Zusammenhang mit seinen Publikationen betrachtet werden, dieser Teil untersucht daher das wissenschaftliche Wirken Bertholds. Anhand der aktuellen Quellenlage wird der Bestand seiner Werke aufgearbeitet und katalogisiert. Die vollständige Bibliografie ermöglicht die Bestimmung von Schwerpunkten in Bertholds wissenschaftlichen Untersuchungen. So bietet diese erste Monografie über Gottfried D. W. Berthold ein Fundament für die Beurteilung seines OEuvres und seiner Wirkung auf die Phykologie bzw. die Botanik. Sie ist eine angemessene Erinnerung an ihn und ermöglicht eine gebührende Würdigung seines Wirkens. Die vorliegende Studie ist ein Beitrag zur Universitäts- und Wissenschaftsgeschichte der Georgia Augusta.

Abstract

Studies have shown that alterations of epigenetics and microRNAs (miRNAs) play critical roles in the initiation and progression of human cancer. Epigenetic silencing of tumor suppressor genes in cancer cells is generally mediated by DNA hypermethylation of CpG island promoter and histone modification such as methylation of histone H3 lysine 9 (H3K9) and tri-methylation of H3K27. MiRNAs are small non-coding RNAs that regulate expression of various target genes. Specific miRNAs are aberrantly expressed and play roles as tumor suppressors or oncogenes during carcinogenesis. Important tumor suppressor miRNAs are silenced by epigenetic alterations, resulting in activation of target oncogenes in human malignancies. Stem cells have the ability to perpetuate themselves through self-renewal and to generate mature cells of various tissues through differentiation. Accumulating evidence suggests that a subpopulation of cancer cells with distinct stem-like properties is responsible for tumor initiation, invasive growth, and metastasis formation, which is defined as cancer stem cells. Cancer stem cells are considered to be resistant to conventional chemotherapy and radiation therapy, suggesting that these cells are important targets of cancer therapy. DNA methylation, histone modification and miRNAs may be deeply involved in stem-like properties in cancer cells. Restoring the expression of tumor suppressor genes and miRNAs by chromatin modifying drugs may be a promising therapeutic approach for cancer stem cells. In this Research Topic, we discuss about alterations of epigenetics and miRNAs in cancer and cancer stem cell and understand the molecular mechanism underlying the formation of cancer stem cell, which may provide a novel insight for treatment of refractory cancer.

Abstract

The name DGGTB (Deutsche Gesellschaft für Geschichte und Theorie der Biologie; German Society for the History and Theory of Biology) reflects recent history as well as German tradition. The Society is a relatively late addition to a series of German societies of science and medicine that began with the »Deutsche Gesellschaft für Geschichte der Medizin und der Naturwissenschaften«, founded in 1910 by Leipzig University's Karl Sudhoff (1853-1938), who wrote: »We want to establish a ,German' society in order to gather German-speaking historians together in our special disciplines so that they form the core of an international society...«. Yet Sudhoff, at this time of burgeoning academic internationalism, was »quite willing« to accommodate the wishes of a number of founding members and »drop the word German in the title of the Society and have it merge with an international society«. The founding and naming of the Society at that time derived from a specific set of historical circumstances, and the same was true some 80 years later when in 1991, in the wake of German reunification, the »Deutsche Gesellschaft für Geschichte und Theorie der Biologie« was founded. From the start, the Society has been committed to bringing studies in the history and philosophy of biology to a wide audience, using for this purpose its Jahrbuch für Geschichte und Theorie der Biologie. Parallel to the Jahrbuch, the Verhandlungen zur Geschichte und Theorie der Biologie has become the by now traditional medium for the publication of papers delivered at the Society's annual meetings. In 2005 the Jahrbuch was renamed Annals of the History and Philosophy of Biology, reflecting the Society's internationalist aspirations in addressing comparative biology as a subject of historical and philosophical studies.

Abstract

Cancer is a transnational condition involving the unprecedented flow of health information, technologies, and people across national borders. Such movement raises questions about the nature of therapeutic citizenship, how and where structurally vulnerable populations obtain care, and the political geography of blame associated with this disease. This volume brings together cutting-edge anthropological research carried out across North and South America, Europe, Africa and Asia, representing low-, middle- and high-resource countries with a diversity of national health care systems. Contributors ethnographically map the varied nature of cancer experiences and articulate the multiplicity of meanings that survivorship, risk, charity and care entail. They explore institutional frameworks shaping local responses to cancer and underlying political forces and structural variables that frame individual experiences. Of particular concern is the need to interrogate underlying assumptions of research designs that may lead to the naturalizing of hidden agendas or intentions. Running throughout the chapters, moreover, are considerations of moral and ethical issues related to cancer treatment and research. Thematic emphases include the importance of local biologies in the framing of cancer diagnosis and treatment protocols, uncertainty and ambiguity in definitions of biosociality, shifting definitions of patienthood, and the sociality of care and support.

Abstract

Endocrinological research early recognized the importance of intercellular interactions and realized the importance of glutamatergic and GABAergic signaling. In turn this signalling depends on elaborate interactions between astrocytes and neurons, without which neurons would be unable to produce, reuse and metabolize transmitter glutamate and GABA. Details of these subjects are described in this Research Topic by key investigators in this field. It focuses on the intricate and extremely swift pathway producing these amino acid transmitters from glucose in brain but also discusses difficulties in determining expression of some of the necessary genes in astrocytes and related processes in pancreatic islets. However, it does not discuss how closely associated astrocytes and neurons are anatomically, enabling these interactions. This is elegantly shown in this cover image, kindly provided by Professor Andreas Reichenbach (University of Leipzig, Germany).

Abstract

It is well known that the activation of the circulating renin angiotensin system is involved in cardiovascular pathology including hypertension, heart failure and is responsible for important organic changes induced by diabetes. Evidence is now available that independently of the classical system, there are local renin angiotensin systems in different organs including the heart, circulatory vessels, kidney and probably brain and that components of these local systems participate in important aspects of physiology and pathology. Of particular interest is the presence of an intracellular component-the so called intracrine renin angiotensin system, which seems related to regulation of several cellular functions. A discussion of the different aspects of this important topic is of relevance to cell biology, endocrinology, physiology and pathology and justify a comprehensive presentation to the scientific community organized by experts in their respective fields.

Abstract

When organisms are deliberately or accidentally introduced into a new ecosystem a biological invasion may take place. These so-called ‘invasive species’ may establish, spread and ecologically alter the invaded community. Biological invasions by animals, plants, pathogens or vectors are one of the greatest environmental and economic threats and, along with habitat destruction, a leading cause of global biodiversity loss. In this book, more than 50 worldwide invasion scientists cover our current understanding of biological invasions, its impacts, patterns and mechanisms in both aquatic and terrestrial systems.

Abstract

In these conference proceedings particular attention is paid to the performance of burials and burial rites between 1300 and 750 BC. A change in burial customs took place in large parts of central Europe during the 13th century BC. The dead were no longer buried in inhumation graves – as was customary until then – but were burned and laid to rest in urns. This transformation of burial customs is probably connected to far reaching changes in society and religious beliefs.

In dem vorliegenden Kongressband werden Bestattung und Ritual in der Region zwischen Mitteleuropa und Griechenland zwischen 1300 und 750 v. Chr. besondere Aufmerksamkeit geschenkt. Im 13. Jahrhundert v. Chr. fand in weiten Teilen Mitteleuropas eine radikale Veränderung der Grabsitten statt. Die Toten wurden nicht mehr, wie bis dahin üblich, in Körpergräbern bestattet, sondern verbrannt und in Urnen beigesetzt. Es ist wahrscheinlich, dass sich hinter dem Wandel des Begräbnisrituals weitreichende Veränderungen der Gesellschaft und der religiösen Vorstellungen verbergen.
