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 RNA interference, the ecdysone receptor crystal structures and structure activity relationships, etc. Each article may also be read independently, as a review of that particular subject. Complete up-to-date coverage of many important topics - the book is divisible into five conceptual areas: (1) Distribution and diversity of ecdysteroids in the two kingdoms is still basis, (2) In the post-genomic era, ecdysteroid genetic hierarchies in insect growth and reproduction, (3) Role of cross talk of genes and growth factors in ecdysteroid titers and signaling, (4) Ecdysteroids function through nuclear and membrane receptors, and (5) Ecdysteroids in modern agriculture, medicine, doping and ecotoxicology. Each of the 23 chapters is written by scientists active in the reviewed research area and a truly distinguished international team of contributors has been chosen. Ecdysone, Structures and Functions will be of immense use and contains essential information for scientists, students, and professionals alike in entomology, endocrinology, physiology, chemistry, and agricultural, plant, biomedicine and environmental sciences. |

| 22r intake manifold diagram: Aging Methods and Protocols Yvonne A. Barnett, Christopher R. Barnett, 2010-11-09 Aging is an almost universal process within biological systems, one which leads to a decline in functional capacity, disease onset, and eventually death. There has been much interest in recent years to elucidate the molecular mec- nisms that underlie the aging process. Many theories have been proposed since the last century that aim to explain the causes of aging. There is no one theory that completely satisfies the phenotype of aging, but genetics and environm- tal factors play an important role in the etiology of age-related pathologies and the aging process. However, there is still much to be learned about the aging process which has been termed one of the last great frontiers in biology. De- graphic changes worldwide are leading to increased average life expectancies within our populations. These changes in population characteristics will impact upon the economies of the supporting society, with increasing healthcare and infrastructural costs arising from the prevalence of age-related pathologies and other physical disabilities associated with advancing years. Many researchers worldwide are working in the attempt to identify key cellular processes through which it might one day be possible to slow down the aging process and thus increase the health span of humans. Numerous research projects—from the cellular through to tissue, organ, and whole organism studies—are currently underway to investigate the mul- factorial aging process. |
