Extremely Violent Societies: Mass Violence in the Twentieth Century World

In this groundbreaking book Christian Gerlach traces the social roots of the extraordinary processes of human destruction involved in mass violence throughout the twentieth century. He argues that terms such as 'genocide' and 'ethnic cleansing' are too narrow to explain the diverse motives and interests that cause violence to spread in varying forms and intensities. From killings and expulsions to enforced hunger, collective rape, strategic bombing, forced labour and imprisonment he explores what happened before, during, and after periods of widespread bloodshed in countries such as Armenia, Indonesia, Bangladesh, Nazi-occupied Greece and in anti-guerilla wars worldwide in order to highlight the crucial role of socio-economic pressures in the generation of group conflicts. By focussing on why so many different people participated in or supported mass violence, and why different groups were victimized, he offers us a new way of understanding one of the most disturbing phenomena of our times.

In pediatric lymphoblastic leukemia of B-cell origin, a small population of primitive blast cells is noncycling, suggesting them to be leukemia stem cell candidates

Kinetic investigations in pediatric acute lymphoblastic leukemia (ALL) are based on all blast cells and, therefore, reflect the proliferative characteristics of the predominant immunophenotype of leukemic cells. Nothing is known about proliferation of immunologically defined rare subpopulations of leukemic cells. In this study, mononuclear cells from the bone marrow of 15 children with untreated CD19 B-cell precursor ALL were examined for proliferative features according to the immunophenotype. After exclusion of highly proliferating residual normal hematopoietic cells, ∼ 3% of blast cells were CD19 and showed a low percentage of cells in S-phase assessed by the bromodeoxyuridine labeling index (BrdU-LI): median BrdU-LI, 0.19% [interquartile range (IQR), 0.15-0.40%]. In contrast, a median BrdU-LI of 7.2% (IQR, 5.7-8.8%) was found for the major CD19 blast cell compartment. Staining smears of sorted CD19 cells for CD10 or CD34 revealed a small fraction of CD19CD10 or CD19CD34 blast cells. These cells were almost nonproliferating with a median BrdU-LI of <0.1% (IQR, 0-0.2%). This proliferative behavior is suggestive of a stem/progenitor cell function and, in addition, the low proliferative activity might render them more resistant to an antiproliferation-based chemotherapy. However, xenotransplantation experiments will be necessary to demonstrate a possible stem cell function.

European guidelines on management of restless legs syndrome: report of a joint task force by the European Federation of Neurological Societies, the European Neurological Society and the European Sleep Research Society

Since the publication of the first European Federation of Neurological Societies (EFNS) guidelines in 2005 on the management of restless legs syndrome (RLS; also known as Willis-Ekbom disease), there have been major therapeutic advances in the field. Furthermore, the management of RLS is now a part of routine neurological practice in Europe. New drugs have also become available, and further randomized controlled trials have been undertaken. These guidelines were undertaken by the EFNS in collaboration with the European Neurological Society and the European Sleep Research Society.

The Importance of Place Names in the Search for Ecosystem-Like Concepts in Indigenous Societies: An Example from the Bolivian Andes

This paper aims to deepen the search for ecosystem-like concepts in indigenous societies by highlighting the importance of place names used by Quechua indigenous farmers from the central Bolivian Andes. Villagers from two communities in the Tunari Mountain Range were asked to list, describe, map and categorize the places they knew on their community’s territory. Results show that place names capture spatially explicit units which integrate biotic and abiotic nature and humans, and that there is an emphasis on topographic terms, highlighting the importance of geodiversity. Farmers’ perspectives differ from the classical view of ecosystems because they ‘humanize’ places, considering them as living beings with agency. Consequently, they do not make a distinction between natural and cultural heritage. Their perspective of the environment is that of a personalized, dynamic relationship with the elements of the natural world that are perceived as living entities. A practical implication of the findings for sustainable development is that since places names make the links between people and the elements of the landscape, toponymy is a tool for ecosystem management rooted in indigenous knowledge. Because place names refer to holistic units linked with people’s experience and spatially explicit, they can be used as an entry point to implement an intercultural dialogue for more sustainable land management.
