Описание: This updated second edition of the highly successful "Seafood and Freshwater Toxins" provides an expanded exploration of the chemistry of toxins produced
by marine bacteria and plants. Comprehensive coverage includes the ecobiology, pharmacology, chemistry, detection, legal ownership rights, and toxicology of each group of toxins.
Chapters highlight newly discovered toxins such as pfiesteria, ostreocin, ovatatoxin, cyclic imines, and spirolides.
The authors also discuss toxin monitoring programs and
international validation of new detection methods. Featuring contributions from international experts, this text is an essential reference for food technologists, pharmacologists,
toxicologists and food safety inspectors, microbiologists, and chemists.

Описание: Viscoelasticandtransportpropertiesofpolymersintheliquid(solution, melt)or liquid-like (rubber) state determine their processing and application to a large extent and are of basic physical interest 1--3]. An understanding of these dynamic properties at a molecular level, therefore, is of great importance. However, thisunderstandingiscomplicatedbythefactsthatdi?erentmotional processes may occur on di?erent length scales and that the dynamics are governed by universal chain properties as well as by the special chemical structure of the monomer units 4,5]. The earliest and simplest approach in this direction starts from Langevin equations with solutions comprising a spectrum of relaxation modes 1--4]. Special features are the incorporation of entropic forces (Rouse model, 6]) which relax uctuations of reduced entropy, and of hydrodynamic interactions (Zimm model, 7]) which couple segmental motions via long-range back ow elds in polymer solutions, and the inclusion of topological constraints or entanglements (reptation or tube model, 8--10]) which are mutually imposed within a dense ensemble of chains. Another approach, neglecting the details of the chemical structure and concentratingontheuniversalelementsofchainrelaxation, isbasedondynamic scalingconsiderations 4,11].Inparticularinpolymersolutions, thisapproach o?ers an elegant tool to specify the general trends of polymer dynamics, although it su?ers from the lack of a molecular interpretation. A real test of these theoretical approaches requires microscopic methods, which simultaneously give direct access to the space and time evolution of the segmental di?usion. Here, quasi-elastic scattering methods play a crucial role sincetheyallowthemeasurementofthecorrespondingcorrelationfunctions.In particular, thehigh-resolutionneutronspinecho(NSE)spectroscopy 12--15]is very suitable for such investigations since this method covers an appropriate range in time (0.005)t/ns)40) and space (r/nm 15). Furthermore, the possibilityoflabellingbyhydrogen-deuteriumexchangeallowstheobservation of single-chain behavior even in the melt.

Описание: This succinct volume addresses the production of inactive, potentially toxic proteins in the absence of correct protein folding and the resultant neurodegenerative diseases. Other topics include intrinsic disorder in protein structure and function and the effects of molten globules on protein toxicity. This concise and yet thorough text also discusses using toxin structure as a model for studying structural and functional aspects of protein chemistry.
Protein Toxins in Modeling Biochemistry, a SpringerBrief, is essential reading for advanced researchers, scientists and advanced graduate students interested in protein chemistry and related areas of biochemistry and molecular science.
