    The women on stieve's list: Victims of national socialism whose bodies were used for anatomical research

    Full text link
    Research on the history of anatomy in the Third Reich has often concentrated on the influence of the National Socialist (NS) regime on anatomists and their consequent unethical activities. Only recently, the focus has shifted to NS victims whose bodies were used for anatomical purposes. As a first approach to learning more about the victims, this study investigated the persons whose names Hermann Stieve, chairman of the Anatomical Department at the University of Berlin, had listed after using their bodies for his research. The study draws a group portrait and recounts selected biographies of the 174 women and eight men on the list. Most women were of reproductive age, two‐thirds were German and a majority was executed for political reasons. Among the executed were at least two pregnant women. The corrected names, biographical data, and nationalities of all persons on the list are published here. None of them volunteered to be dissected, nor were the anatomists at the time interested in the victims' personal background. Future work will have to focus on the investigation of further biographies so that numbers can be turned back into people. This history is a reminder to modern anatomy that ethical body procurement and the anatomists' caring about the body donor is of the utmost importance in a discipline that introduces students to professional ethics in the medical teaching curriculum.

    The anatomist Hans Elias: A Jewish German in exile

    Full text link
    Hans Elias (1907 to 1985) was an anatomist, an educator, a mathematician, a cinematographer, a painter, and a sculptor. Above all, he was a German of Jewish descent, who had to leave his home country because of the policies of the National Socialist (NS) regime. He spent his life in exile, first in Italy and then in the United States. His biography is exemplary for a generation of younger expatriates from National Socialist Germany who had to find a new professional career under difficult circumstances. Elias was a greatly productive morphologist whose artistic talent led to the foundation of the new science of stereology and made him an expert in scientific cinematography. He struggled hard to fulfill his own high expectations of himself in terms of his effectiveness as a scientist, educator, and politically acting man in this world. Throughout his life this strong‐willed and outspoken man never lost his great fondness for Germany and many of its people, while reserving some of his sharpest criticism for fellow anatomists who were active in National Socialist Germany, among them his friend Hermann Stieve, Max Clara, and Heinrich von Hayek. Hans Elias' life is well documented in his unpublished diaries and memoirs, and thus allows fresh insights into a time period when some anatomists were among the first victims of NS policies and other anatomists became involved in the execution of such policies.

    Research on bodies of the executed in German anatomy: An accepted method that changed during the Third Reich. Study of anatomical journals from 1924 to 1951

    Full text link
    While it is known that bodies of the executed were used for anatomical research in Germany during the Third Reich, it is unclear whether this type of work was unique to the time period or more common in Germany than elsewhere. The dissected persons and the anatomists involved have not been fully investigated. This study of anatomical journals from 1924 to 1951 shows that 166 out of 7,438 [2.2%] German language articles mentioned the use of “material” from the bodies of executed persons. In comparison, only 2 out of 4,702 English language articles explicitly mentioned bodies of the executed. From 1924 to1932, 33 of a total of 3,734 [1%] German articles listed the use of the executed. From 1933 to 1938 the number rose to 46 out of 2,265 [2%], and increased again from 1939 to 1945 to 73 out of 984 [7%]. After the war 15 out of 455 [3%] still dealt with “material” from the executed. German anatomists' familiarity with the use of the executed as a standard for healthy tissues even before 1933 may have contributed to the ease with which they accepted the “opportunities” (large‐scale studies and research on women) presented to them by unlimited access to bodies of the executed provided by the abusive National Socialist (NS) legislation and continued using them for some years after the war. German postwar anatomy was built in part on the bodies of NS victims. Information given in some publications will help with further identification of these victims. Clin.

    Feast Your Eyes on This—Markets in Ponta Delgada, Azores, and Granada and Barcelona, Spain: A Photographic Essay

    Before Publix, Winn Dixie and other chain supermarkets emerged in the 20th Century, there were markets on open, cobblestone streets somewhere near the center of many small towns throughout America. But for contemporary Americans, the open-air market has become more remote and might now be a small area in a park or public lot where weekend farmers’ markets and flea markets offer a few bins of organic fruits and vegetables and homemade or handmade goods. While the tradition has disappeared from many U.S. cities, permanent, open-air markets still thrive in Africa, Asia, and Europe where vendors set up carts and stalls alongside or even in streets and alleyways where vehicles are prohibited

    Szenischer Raum. Zur Vieldeutigkeit pädagogischer Lernorte

    Get PDF
    Die Frage nach der pädagogischen Bedeutung des Raumes stellt sich nicht erst in spezifischen Werkstätten, die der Materialität eine besondere Relevanz für ausgewählte Themenstellungen zuweisen, sondern im räumlich – szenischen Charakter von Kommunikation, Erziehung, Lehren und Lernen selbst. Welchen Einfluss entfalten Räume auf pädagogische Prozesse und wie können sie zu einem experimentellen Raum werden? In diesem Beitrag wird nach Einflüssen und Möglichkeiten der Raumerfahrung und -orientierung in Hochschulen, Schulen und Kindertageseinrichtungen gefragt. In Anknüpfung an phänomenologische Perspektiven zum szenischen Charakter des Raumes wird ein Didaktik- und Architekturprojekt an der TH Köln vorgestellt. Im Fokus stehen die Vieldeutigkeit, das Ereignishafte, die Differenzen und Irritationen von Räumen, die als entscheidendes Bildungs-Moment von Werkstätten hervorgehoben werden. (DIPF/Orig.

    In vivo testing of a bioabsorbable magnesium alloy serving as total ossicular replacement prostheses

    Magnesium alloys have been investigated in different fields of medicine and represent a promising biomaterial for implants due to characteristics like bioabsorbability and osteoinduction. The objective of this study was to evaluate the usability of magnesium as implant material in middle ear surgery. Magnesium implants were placed into the right middle ear of eighteen New Zealand White rabbits. Nine animals were euthanized after four weeks and nine animals after three month. The petrous bones were removed and embedded in epoxy resin. The specimens were then polished, stained and evaluated with the aid of a light microscope. The histological examination revealed a good biocompatibility. After four weeks, a beginning corrosion of the implant's surface and low amount of trabecular bone formation in the area of the stapes base plate was observed. A considerable degradation of implants and obvious bone formation was found three month after implantation. The magnesium alloy used in the present study partly corroded too fast, so that a complete bone reconstruction could not be established in time. The increased osteoinduction on the stapes base plate resulted in a tight bone-implant bonding. Thus, a promising application of magnesium could be a coating of biomaterials in order to improve the bony integration of implants. © The Author(s) 2012 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav

    Mesoporous silica films as a novel biomaterial: Applications in the middle ear

    Get PDF
    In this tutorial review we present the process of the development of functional implants using mesoporous silica. The different steps from chemical synthesis and physicochemical characterization followed by in vitro testing in cell culture assays to clinically relevant in vivo animal studies are examined. Since the end of the 1990s, mesoporous silicas have been considered as biomaterials. Numerous investigations have demonstrated their non-toxic and biocompatible properties. These qualities in combination with the unique properties of high surface area and pore volume, uniform and tunable pore sizes and chemical modifiability are the reasons for the great scientific interest in this field. Here we show that besides bulk materials or mesoporous silica nanoparticles, mesoporous silica films are highly promising as coatings on medical prostheses or implants. We report on the development of functionalized mesoporous silica materials specifically for middle ear applications. Middle ear prostheses are used to restore the sound transmission through this air-filled cavity when the small bones of the middle air (the ossicular chain) have been destroyed by disease or by accidents. In addition to optimal restoration of sound transmission, this technique bears several challenges, e.g. an ongoing bacterial infection or the displacement of the prosthesis due to insufficient fixation. To improve the healing process, a mesoporous silica coating was established on ceramic middle ear prostheses, which then served as a base for further functionalizations. For example, the bone growth factor BMP2 was locally attached to the coating in order to improve the fixation of the prosthesis by forming a bony connection to the remainder of the ear bones. Further, an implant-based local drug delivery system for the antibiotic ciprofloxacin was developed with the aim of fighting bacterial infections. Further possibilities using mesoporous silica nanoparticles as part of a composite on an implant are briefly discussed. © The Royal Society of Chemistry 2013
