Under the name of programmed cell death (PCD) are included diverse molecular mechanism of cell suicide which play an essential role in the development of multicellular organisms. The best known PCD mechanism in multicellular organisms is called apoptosis. However, recent studies indicate that PCD is also present in protozoa and unicellular eukaryotes. The eleven chapters of this book give the reader a comprehensive update of the progress in the understanding of the mechanisms of PCD in protozoa. The chapters have been written by experts in this field of research and are arranged following...

Combining research approaches from biology, philosophy and linguistics, the field of Biosemiotics proposes that animals, plants and single cells all engage in semiosis the conversion of objective signals into conventional signs. This has important implications and applications for issues ranging from natural selection to animal behavior and human psychology, leaving biosemiotics at the cutting edge of the research on the fundamentals of life.

Drawing on an international expertise, the book details the history and study of biosemiotics, and provides a state-of-the-art summary of the...

Three-dimensional x-ray diffraction (3DXRD) microscopy is a novel experimental method for structural characterisation of polycrystalline materials. The position, morphology, phase, strain and crystallographic orientation of hundreds of grains or sub-grain embedded within mm-cm thick specimens can be determined simultaneously. Furthermore, the dynamics of the individual structural elements can be monitored during typical processes such as deformation or annealing.

The book gives a comprehensive account of the methodology followed by a summary of selected applications. The...

Fitness and adaptation are fundamental characteristics of plant and animal species, enabling them to survive in their environment and to adapt to the inevitable changes in this environment. This is true for both the genetic resources of natural ecosystems as well as those used in agricultural production.

Extensive genetic variation exists between varieties/breeds in a species and amongst individuals within breeds. This variation has developed over very long periods of time. A major ongoing challenge is how to best utilize this variation to meet short-term demands...

NanoScience in Biomedicine provides up-to-date information in the frontier fields of nano biomedicine focusing on basic concepts and recent developments in many topical areas including particular nanomaterials synthesis, field emission of carbon nanotubes, flexible dye-sensitized nano-porous films, magnetic nanofluids, and intrinsically electroconducting nanoparticles. Novel methods of synthesizing nanoscale biomaterials and their applications in biomedicine are also included such as nano-sized materials for drug delivery, bioactive molecules for regenerative medicine, nanoscale...

Ecdysone is the steroidal prohormone of the major insect moulting hormone 20-hydroxyecdysone. It groups with its homologues the steroidal molting hormones in arthropods, but they also occur in other phyla where they can play different roles. Besides ecdysteroids appear in many plants mostly as protection agents (toxins or antifeedants) against herbivorous insects.

The important developments and achievements in modern ecdysone science since the first edition in 1989 by J. Koolman have led to this new revised, expanded and retitled reference work. New chapters in this edition include...
