Climate change is a complex phenomenon with a wide range of impacts on the environment. Biotic and abiotic stress are a result of climate change. Abiotic stress is caused by primary and secondary stresses which are an impediment to plant productivity. Prolonged exposure to these stresses results in altered metabolism and damage to biomolecules. Plants evolve defense mechanisms to withstand these stresses, e.g. synthesis of osmolytes, osmoprotectants, and antioxidants. Stress responsive genes and gene products including expressed proteins are implicated in conferring tolerance to the plant. This volume will provide the reader with a wide spectrum of information, including vital references. It...
This book provides a complete overview of cucurbituril chemistry, covering fundamental aspects including history, synthesis and host-guest chemistry.
This volume educates physicians on the basic knowledge of ESD, from indication of this technique to assessing suitability and technical aspects of each important step. The text is structured to guide readers to understand the principles, including history, why ESD was designed and developed, indications, as well as how to evaluate lesions and perform actual procedures. Abundant photographs and diagrams illustrate the key points and promote “pattern recognition”. The text also introduces gastroenterologists to early gastrointestinal lesions, which have not been recognized in clinical practice for many years. To assist in the treatment process of ESD, highly practical information is provided, separated by different anatomical locations, as well as management of complications. The volume is also accompanied by an online video library. Written by experts in Asian countries with vast experience with this technique, as well as experts from the U.S., South America, and Europe, Endoscopic Submucosal Dissection: Principles and Practice provides a major reference for gastroenterologists and surgeons on ESD.
This truly comprehensive treatise of foldamers, from synthesis to applications in bio-, material-, and nanoscience is at once an introduction to the topic, while providing in-depth accounts on various aspects clearly aimed at the specialist. The book is clearly structured, with the first part concentrating on structure and foldamer design concepts, while the second part covers functional aspects from properties to applications. The international team of expert authors provides overviews of synthetic approaches as well as analytical techniques.
The Chemical Components of Tobacco and Tobacco Smoke chronicles the extraordinary progress made by scientists in the field of tobacco science, from its beginnings in the early 1800s to the present. This comprehensive text provides over 6000 references on more than 8400 components identified in tobacco and tobacco smoke.Authored by two longtime rese
In biological systems, molecules hierarchically form ordered assemblies and macroscopic substances, as exemplified by the assembly of proteins. The development of such systems using oligomeric macromolecules obtained by organic synthesis can provide insights into biological phenomena and will lead to the creation of new materials. In this regard, synthetic double helix molecules are attractive subjects of study because they have an important structural motif that appears widely in nature and can exhibit dynamic structural change. This thesis describes an unprecedented bottom-up approach using synthetic ethynylhelicene oligomers, which form dynamic double helices in organic media. Oligomer synthesis, homo- and hetero-double helix formation, and higher assembly formation due to intercomplex interactions are documented. The hierarchical assembly formation is a cogent reminder of the assembly of biological proteins that create living creatures. Also notable here is the demonstration of a methodology of providing diverse hetero-double helices and their higher assemblies by changing the combination of oligomers, which can be another advantage of this synthetic system.
