Several years ago, when the discovery of catalytic RNA was recognized in a public manner,many people asked if new ?elds of therapy would soon be available. Although some tentative positive answers were given,nobody would say with certainty that RNA of various kinds was a truly promising means of altering gene expression. In fact,over the past decade,both our knowledge of RNAs with different functions and the utility of RNA in the inhibition or enhancement of gene expression have occurred with great drama. We proceeded in terms of possible therapeutic tools from RNase P and group I introns through "hammerhead" RNA enzymes, antisense technology, and more recently, to RNAi and its derivatives. A useful practical method of RNA delivery in animals will complete the picture. The diversity of RNA and the varied role of it inside cells and in therapy should be a tremendous challenge for young molecular biologists. This volume will make their task easier. Sidney Altman Sterling Professor of Molecular,Cellular & Devel- mental Biology,Nobel Laureate Department of Molecular,Cellular and Developm- tal Biology Yale University V NGTPR 4/23/05 1:00 PM Page VI VI Foreword Delivery of nucleic acids to cells in an animal remains a challenging problem. It is the major obstacle to success of therapeutic approaches using genes and oli- nucleotides,including siRNAs. Solutions found so far by chemists are satisfactory only for transfection of cells in culture.

In order to feed the world, global agriculture will have to double food production by 2050. As a result, the use of soils with fertilizers and pesticides in agronomic ecosystems will increase, taking into account the sustainability of these systems and also the provision of food security. Thus, soil ecosystems, their health, and their quality are directly involved in sustainable agronomical practices, and it is important to recognize the important role of soil microbial communities such as mycorrhizal fungi, their biodiversity, interactions, and functioning. Soil ecosystems are under the threat of biodiversity loss due to an increase of cultivated areas and agronomic exploitation intensity. Also, changes in land use alter the structure and function of ecosystems where biodiversity is vital in the ecosystem. Soils are a major aid in food production in all terrestrial ecosystems; however, this means they are also involved in gas emission and global warming. Thus, in agronomic ecosystems, several mitigation practices have been proposed to promote the increase of carbon soil stock, and the reduction of warming gas emission from soils. In South America, most of the rural population depends economically on agriculture and usually works in family units. New, organic, safe, and sustainable agro-forestry practices must be applied to support local communities and countries to achieve hunger eradication, rural poverty reduction, and sustainable development. This book compiles new information for mycorrhizal occurrence in natural and anthropic environments in South America. It includes new reports of mycorrhizal fungi diversity along different mycorrhizal types and their effect on plant communities, plant invasions, the use of mycorrhizal fungi for ecological and sustainable studies, management programs of natural and agroecosystems, and forestry and food-secure production. This book fills the gaps in biodiversity knowledge, management and safe food production of mycorrhizas. It should be a valuable help to researchers, professors and students, to aid in use of mycorrhizal fungi while also focusing on their biodiversity, sustainable safe food production, and conservation perspectives.
Biotic stresses cause yield loss of 31-42% in crops in addition to 6-20% during post-harvest stage. Understanding interaction of crop plants to the biotic stresses caused by insects, bacteria, fungi, viruses, and oomycetes, etc. is important to develop resistant crop varieties. Knowledge on the advanced genetic and genomic crop improvement strategies including molecular breeding, transgenics, genomic-assisted breeding and the recently emerging genome editing for developing resistant varieties in technical crops is imperative for addressing FHEE (food, health, energy and environment) security. Whole genome sequencing of these crops followed by genotyping-by-sequencing have facilitated precise information about the genes conferring resistance useful for gene discovery, allele mining and shuttle breeding which in turn opened up the scope for 'designing' crop genomes with resistance to biotic stresses. The 15 chapters dedicated to 13 technical crops and 2 technical crop groups in this volume will deliberate on different types of biotic stress agents and their effects on and interaction with crop plants; will enumerate on the available genetic diversity with regard to biotic stress resistance among available cultivars; illuminate on the potential gene pools for utilization in interspecific gene transfer; will brief on the classical genetics of stress resistance and traditional breeding for transferring them to their cultivated counterparts; will enunciate the success stories of genetic engineering for developing biotic stress resistant varieties; will discuss on molecular mapping of genes and QTLs underlying biotic stress resistance and their marker-assisted introgression into elite varieties; will enunciate on different emerging genomics-aided techniques including genomic selection, allele mining, gene discovery and gene pyramiding for developing resistant crop varieties with higher quantity and quality; and will also elaborate some case studies on genome editing focusing on specific genes for generating disease and insect resistant crops.
Early anthropological evidence for plant use as medicine is 60,000 years old as reported from the Neanderthal grave in Iraq. The importance of plants as medicine is further supported by archeological evidence from Asia and the Middle East. Today, around 1.4 billion people in South Asia alone have no access to modern health care, and rely instead on traditional medicine to alleviate various symptoms. On a global basis, approximately 50 to 80 thousand plant species are used either natively or as pharmaceutical derivatives for life-threatening conditions that include diabetes, hypertension and cancers. As the demand for plant-based medicine rises, there is an unmet need to investigate the quality, safety and efficacy of these herbals by the "scientific methods". Current research on drug discovery from medicinal plants involves a multifaceted approach combining botanical, phytochemical, analytical, and molecular techniques. For instance, high throughput robotic screens have been developed by industry; it is now possible to carry out 50,000 tests per day in the search for compounds which act on a key enzyme or a subset of receptors. This and other bioassays thus offer hope that one may eventually identify compounds for treating a variety of diseases or conditions. However, drug development from natural products is not without its problems. Frequent challenges encountered include the procurement of raw materials, the selection and implementation of appropriate high-throughput bioassays, and the scaling-up of preparative procedures. Research scientists should therefore arm themselves with the right tools and knowledge in order to harness the vast potentials of plant-based therapeutics. The main objective of Plant and Human Health is to serve as a comprehensive guide for this endeavor. Volume 1 highlights how humans from specific areas or cultures use indigenous plants. Despite technological developments, herbal drugs still occupy a preferential place in a majority of the population in the third world and have slowly taken roots as alternative medicine in the West. The integration of modern science with traditional uses of herbal drugs is important for our understanding of this ethnobotanical relationship. Volume 2 deals with the phytochemical and molecular characterization of herbal medicine. Specifically, it will focus on the secondary metabolic compounds which afford protection against diseases. Lastly, Volume 3 focuses on the physiological mechanisms by which the active ingredients of medicinal plants serve to improve human health. Together this three-volume collection intends to bridge the gap for herbalists, traditional and modern medical practitioners, and students and researchers in botany and horticulture.

The last section examines the utilization of biomass for the production of bioactive materials, including biofertilizers, bioadsorbents, activated carbon, nano-materials, and pigments. This book explores the relation between biofuels and the sustainable development goals (SDGs) 7.
Biomaterials are advanced materials that garner interdisciplinary research. Wastewater pollution causes many adverse effects on human health and the environment. In order to rectify this, biomaterials and other nanomaterials have been utilized as photocatalysts against environmental waste. In this book, biomaterials are highlighted as a promising material for waste management, as biomaterials are cost-effective, eco-friendly and closer to nature.
The book reviews the history, present, and likely future of intellectual property for plant-related inventions. It describes "what works" and "what does not work" in the current situation and analyzes whether the current intellectual property framework will be able to cope with the rise of genome editing/new breeding technologies (especially CRISPR Cas). Based on trend data, the analysis shows that the current system, including stakeholder initiatives, will most likely not be able to adapt to the technology change. It then evaluates different options for legislators to respond and proposes in detail a new holistic IP system which merges elements of the patent and the plant variety protection system into one new system.
Despite advances in the long-range electrostatic double-layer force, which depends strongly on ionic strength in water by using theoretical models such as DLVO (Derjaguin, Landau, Verwey, and Overbeek), the structure of confined water in air still remains widely unknown and has led to a variety of unexplained phenomena. This book bridges that gap by introducing a newly developed scanning probe miscroscopy (SPM) approach, which enables one to probe confined water at the molecular and atomic scale. Written by the developer of SPM, this book covers this new approach, as well as original approaches to addressing general interfacial water issues. It also introduces the cantilever-based optical interfacial force microscope (COIFM), which was invented by the author along with the methodology. The improved understanding will contribute to liquid-based nano- and bio-technologies such as lab-on-a-chip technologies, nanofluidic devices, dip-pen nanolithography, nano-oxidation, water-based granular interactions, liquid-based nanolubricants, hydration layers in biopolymers, manipulation of biomolecules, protein folding, stability of colloid suspensions, enzyme activity, swelling in clays, development of bioactive surfaces, water columns and ion channeling in membranes and scanning probe microscopy (SPM). It will also contribute to the improved performance of moving components in silicon-based micro-electro-mechanical system (MEMS) devices, where water plays a key role in interfacial interactions.
The main driving force behind the development of new applications
for chitin and its derivative chitosan lies with the fact that
these polysaccharides represent a renewable source of natural
biodegradable polymers. Since chitin is the second most abundant
natural polymer, academic as well as industrial scientists are
faced with a great challenge to find new and practical applications
for this material. This book provides an examination of the state
of the art, and discusses new applications as well as potential
products. Applications of Chitin and Chitosan deals almost
exclusively with applications. Previous books in the field have
devoted less than 30% of their material to commercial or medical
uses.

This thesis presents original research on how to seamlessly integrate electronics with living biological systems. Jia Liu has used silicon nanowires as active sensors to investigate biological signals at the cellular level. He has also designed nanoelectronic networks into flexible, three-dimensional (3D) and macroporous architectures, which mimic the structure of tissue scaffolds for in vitro 3D integrations with synthetic tissues and in vivo implantation by means of syringe injection. Importantly, the results demonstrate 3D interpenetrations of nanoelectronic networks with neural networks, 3D mapping of tissue activity and long-term implantation with minimal immunoresponses. Further, the book discusses potential applications for pharmacological studies, brain activity mapping and nanoelectronics enabled therapies. The findings presented here have gained wide recognition, including a top research ranking by Chemical & Engineering News and being listed among Scientific American's 10 world changing ideas in 2015.
With the erratic changes in climate, crop plants are facing many forms of biotic stresses. When plants are under stress, among several gene families, regulatory genes play a vital role in signal transduction in modulating the expression of genes underpinning several defense pathways and targeting regulatory proteins (viz, transcription factors (TFs)) can be the alternative. Transcription factors directly regulate the downstream R genes and are excellent candidates for disease resistance breeding. Till date, numerous transcription factors have been identified and characterized structurally and functionally. Of them, TF families such as WRKY, NAC, Whirly, Apetala2 (AP2), ethylene responsive elements (ERF) etc. are found to be associated with transcriptional reprogramming of plant defense response. These TFs are responsive to the pathogen's PAMPs/DAMPs - host's PRR protein interactions and specifically binds to the cis-elements of defense genes and regulate their expression. With this background, realizing the importance of TFs in resistance breeding, this book discusses the recent research and developments in this field for various crops.
Nanorobotics and Nanodiagnostics in Integrative Biology and Biomedicine "Nanorobotics and nanodiagnostics" can be defined as a new generation of biohybrid and nanorobotics that translate fundamental biological principles into engineering design rules, or integrative living components into synthetic structures to create biorobots and nanodiagnotics that perform like natural systems. Nanorobots or nanobots are structured of a nanoscale made of individual assemblies. They can be termed as intelligent systems manufactured with self-assembly strategies by chemical, physical and biological approaches. The nanorobot can determine the structure and enhance the adaptability to the environment in interdisciplinary tasks. "Nanorobotics and nanodiagnostics" is a new generation of biohybrid that translates fundamental biological principles into engineering design rules to create biorobots that perform like natural systems. These biorobotics and diagnostics can now perform various missions to be accomplished certain tasks in the research areas such as integrative biology and biomedicine. "Nanorobotics and Nanodiagnostics in Integrative Biology and Biomedicine" sheds light on a comprehensive overview of the multidisciplinary areas that explore nanotherapeutics and nanorobotic manipulation in biology and medicine. It provides up-to-date knowledge of the promising fields of integrative biology and biomedicine for nano-assisted biorobotics and diagnostics to detect and treat diseases that will enable new scientific discoveries.
Achievements today in plant biotechnology have already surpassed all previous expectations. Plant biotechnology, integrated with classical breeding, is now on the verge of creating the evergreen revolution' to solve the world's envisaged tripled demand for food, agricultural commodities and natural products. New biotechnologies are being continuously adapted to agricultural practices, opening new vistas for plant utilization. Plant biotechnology is changing the plant scene in three major areas: (1) growth and development control (vegetative, generative and propagation), (2) protecting plants against the ever-increasing threats of abiotic and biotic stress, (3) expanding the horizons by producing specialty foods, biochemicals and pharmaceuticals. The potential for improving plant and animal productivity and their proper use in agriculture relies largely on newly-developed DNA biotechnology and molecular markers. These techniques enable the selection of successful genotypes, better isolation and cloning of favorable traits, and the creating of transgenic organisms of importance to agriculture. These areas were extensively discussed at the 9th international congress of the International Association of Plant Tissue Culture and Biotechnology, Plant Biotechnology and In Vitro Biology in the 21st Century', which was held in Jerusalem in June 1998. The present book of proceedings contains the variety of scientific achievements and techniques that were presented: Basic and Applied Aspects of Growth, Development and Differentiation; Genetic Manipulations: Transformation and Gene Expression, Hybridization, Haploidization and Mutagenesis; Genetic Stability and Instability, Selection and Variability; Regulation of Primary and Secondary Metabolism; Model Systems: Cell Cycle, Transport and Signal Transduction; Biotechnology for Plant Protection: Abiotic and Biotic Stress; Biotechnology for Crop Improvement: Yield, Quality and Production of Valuable Substances; Novel Micropropagation Methods; New Markets and Commercial Applications; Intellectual Property Rights.
East Asian medicine, biomedical research, and health care policy are framed by their own set of moral and cultural commitments. Chief among these is the influence of Confucian ideas. A rich portrayal is offered of the implications of Confucian moral and ontological understandings for medical decision-making, human embryonic stem cell research, and health care financing. What is offered is a multifaceted insight into what distinguishes East Asian bioethical reflections. This volume opens with an exploration of the Confucian recognition of the family as an entity existing in its own right and which is not reducible to its members or their interests. As the essays in this volume show, this recognition of the family supports a notion of family autonomy that contrasts with Western individualistic accounts of proper medical decision-making.
Anaerobic digestion is a major field for the treatment of waste and wastewater. Lately the focus has been on the quality of the effluent setting new demands for pathogen removal and for successful removal of unwanted chemicals during the anaerobic process. The two volumes on Biomethanation are devoted to presenting the state of art within the science and application of anaerobic digestion. They describe the basic microbiolgical knowledge of importance for understanding the processes of anaerobic bioreactors along with the newest molecular techniques for examining these systems. In addition, the applications for treatment of waste and wastewaters are presented along with the latest knowledge on process control and regulation of anaerobic bioprocesses. Together these two volumes give an overview of a growing area, which previously has never been presented in such a comprehensive way. |
