The biological activity of mycotoxins ranges from weak and/or sometimes positive effects, such as antibacterial activity (see penicillin derivatives derived from Penicillium strains) to strong mutagenic (e. g. aflatoxins, patulin), carcinogenic (e. g. aflatoxins), teratogenic, neurotoxic (e. g. ochratoxins), nephrotoxic (e. g. fumonisins, citrinin), hepatotoxic, and immunotoxic (e. g. ochratoxins, diketopiperazines) activity. Nowadays, many laboratories around the world are specialized in the detection of mycotoxins in food products and contaminated material found in housing. In this volume, a focus on the most important classes of mycotoxins is provided and their chemistry of the last ten years is discussed. In each Section, the individual biological impact is outlined. Sections are arranged according to mycotoxin classes (e. g. aflatoxins) and/or structural classes (e. g. resorcinyl lactones, diketopiperazines). The biology of mycotoxins is also described.
The volumes of this classic series, now referred to simply as "Zechmeister" after its founder, L. Zechmeister, have appeared under the Springer Imprint ever since the series' inauguration in 1938. It is therefore not really surprising to find out that the list of contributing authors, who were awarded a Nobel Prize, is quite long: Kurt Alder, Derek H.R. Barton, George Wells Beadle, Dorothy Crowfoot-Hodgkin, Otto Diels, Hans von Euler-Chelpin, Paul Karrer, Luis Federico Leloir, Linus Pauling, Vladimir Prelog, with Walter Norman Haworth and Adolf F.J. Butenandt serving as members of the editorial board. The volumes contain contributions on various topics related to the origin, distribution, ch...
Analyses of big datasets signal important directions for the archaeology of religion in the Archaic to Mississippian Native North America Across North America, huge data accumulations derived from decades of cultural resource management studies, combined with old museum collections, provide archaeologists with unparalleled opportunities to explore new questions about the lives of ancient native peoples. For many years the topics of technology, economy, and political organization have received the most research attention, while ritual, religion, and symbolic expression have largely been ignored. This was often the case because researchers considered such topics beyond reach of their methods a...
Lauren and Zack lived happily with their four-year-old daughter, Becky, until the tragic day when a car accident tore her from their lives forever.

Zack distracts himself with lavish parties, while Lauren keeps busy with work. But one day, Lauren gets a call from a lawyer. Has Zack finally decided to divorce her? Could he have fallen in love with another woman?
This book offers a radically new and definitive reappraisal of Allied responses to Nazi human experiments and the origins of informed consent. It places the victims and Allied Medical Intelligence officers at centre stage, while providing a full reconstruction of policies on war crimes and trials related to Nazi medical atrocities and genocide.
