The Role of Legumes in the Farming Systems of the Mediterranean Areas: Proceedings of a Workshop on the Role of Legumes in the Farming Systems of the Mediterranean Areas UNDP/ICARDA, Tunis, June 20–24, 1988 (Developments in Plant and Soil Sciences #38)
by A. E. Osman M. M. Ibrahim M. A. JonesLegumes are an important source of protein for humans and animals. They provide nutritionally rich crop residues for animal feed, and playa key role in maintaining the productivity of soils particularly through biological nitro gen fixation. They are, therefore, of immense value in rainfed farming systems. The International Center for Agricultural Research in the Dry Areas (ICARDA) has a responsibility for research on food, pasture, and forage legumes. The Center also has the broad objective of improving livestock production in rainfed farming systems. Although food legumes have be~n known and grown by farmers in the WANA region for a long time, their productivity has remained low and variable. Forage legumes, on the other hand, are not so well known by farmers of the region, and their role in the farming systems is not so well understood. Thus, we need to develop the concept of using forage legumes as crops and to fit them into cropping systems. In its efforts to increase the productivity of food legumes and develop the legume-based crop/livestock systems, ICARDA has established a network of scientists in the different National Agricultural Research Systems in the region. To further strengthen this network, ICARDA convened a workshop on 'The Role of Legumes in the Farming Systems of Mediterranean Areas' in Tunis, Tunisia, 20-24 June 1988. This workshop was co-sponsored by UNDP, who also contributed funds for this publication.
The Role of Microenvironment in Axonal Regeneration: Influences of Lesion-Induced Changes and Glial Implants on the Regeneration of the Postcommissural Fornix (Advances in Anatomy, Embryology and Cell Biology #137)
by Christine C. Stichel-GunkelSince the pioneering studies of Ramon y Cajal the inability of lesioned adult CNS axons to regenerate has been well established. During the past years advancements in molecular, cellular and biochemical knowledge have provided new insights into the extrinsic mechanims underlying regeneration failure. The rapid progress in this field has already led to the development of new concepts for therapeutic manipulations. This book provides a comprehensive overview of structural and molecular changes induced by an invasive CNS lesion and their involvements in regeneration processes. Moreover, it demonstrates the strong growth-promoting actitivies of implanted glial cells. The data is discussed in relation to current knowledge on the mechanisms of axonal degeneration and regeneration and in terms of their relevance for the development of novel therapeutic strategies.
The Role of Neurotransmitters in Brain Injury
by W. D. Dietrich M. Y. T. GlobusNeuroscientists from various disciplines have given extraordinary attention to the role of neurotransmitters in the field of neuronal injury. This volume summarizes the original oral and poster contributions which were presented at the symposium, "The Role of Neurotransmitters in Brain Injury," in Key West, Florida, between June 7-9, 1991. This symposium was the official Satellite of Brain-91, the Fifteenth International Symposium on Cerebral Blood Flow and Metabolism, held in Miami the previous week. The two principal goals of the Key West satellite meeting were to document recent progress and, more importantly, to explore future directions for investigative studies of the role of neurotransmitters in brain injury. To achieve these goals we assembled participants from diverse scientific fields and specialties who brought their collective expertise to discussions on the importance of neurotransmitters in neuronal and vascular injury following brain ischemia, trauma, and epilepsy. Their contributions are reflected in this volume. An important section of this volume is devoted to the role of glutamate and glutamatergic receptors in the development of ischemic neuronal damage. Topics covered include the mechanisms of glutamate and other excitatory amino acids, and the role of underlying injury-induced release different glutamatergic receptors in brain injury, including the NMDA and the non-NMDA receptors. The involvement of other neurotransmitters in the process of ischemic brain injury is well established.
The Role of Organismal Oxidative Stress in the Ecology and Life-History Evolution of Animals (Fascinating Life Sciences)
by David CostantiniThis book illustrates the role of cellular oxidative stress as one of the most important physiological cornerstones in the evolution of biodiversity. The first part of the book provides the fundamentals to navigate the field and analyse the cross-talk between oxidative status homeostasis and other fundamental organismal functions, such as immunity and stress physiology. The second part of the book argues that oxidative stress underpins the astonishing diversity of adaptations to the environments and the evolution of life-history strategies, from growth to reproduction. Unravelling the (un)expected ways through which the need of regulating the organismal oxidative status has influenced the evolution of life, this book presents a novel integrative way of thinking about how a cellular mechanism has shaped the evolution of life and death.
Role of Signaling Pathways in Brain Tumorigenesis
by Mehdi Hayat ShahiThis book provides acomprehensive overview of cell signalling pathways and morphogens in the genesis of brain tumours. It also explains the role of brain tumour stem cells in the brain tumour progression. It also elucidates the novel early biomarkers that can be utilized to diagnose brain tumours. It presents the basic developmental pathways and morphogens, including retinoic acid and TGF-b that promote brain tumorigenesis. The chapters illustrate the role of stem cells and stem cells mediated cell signalling pathways including, Sonic hedgehog, Notch, Wnt in the brain tumour growth. The chapters also emphasize the role of transcription factors, mainlyNanog, Sox, BMI1, HIF1 and Pax6 in the brain tumouriogensis. It highlights the role of NF-kb, Myc and neurotrophins in the brain tumour development. Finally, the book summarizes the potential early therapeutic targets and targeted drug discovery for brain tumours.
Role of the Choroid Plexus in Health and Disease (Physiology in Health and Disease)
by Jeppe Praetorius Bonnie Blazer-Yost Helle DamkierThis book highlights the importance of the choroid plexus, which forms the blood-cerebrospinal fluid barrier and is the site of the major production of the cerebrospinal fluid (CSF). The authors show that this barrier is crucial for maintaining important compositional differences between the blood plasma and the CSF. The choroid plexus epithelial cells also prevent the spread of infectious agents and other blood-borne entities to the brain tissue. Chapter topics range from the production of CSF by electrolyte regulation in the choroid plexus, to details on the selectively transporting nature of this barrier. Further, the authors elaborate on the important roles of CSF in sustaining brain health by providing hydration, solutes, and nutrients to the brain tissue. Readers will also learn how CSF circulates signaling molecules within the compartments of the brain and removes waste products from the brain tissue. Elucidating the regulation of these processes in the choroid plexus is not only important for the readers’ understanding of normal brain development and function, but is also crucial for resolving a variety of cerebral challenges that lead to brain edema, as well as developing treatments for diseases. The book discusses disease models like hydrocephalus, sleep disorders, and age-related dementia. Its comprehensive coverage makes this volume a valuable resource for researchers in cell and neurophysiology, as well as graduate students of the neurosciences.

Rosewood: Endangered Species Conservation and the Rise of Global China
by Annah Lake ZhuA riveting study of the booming rosewood trade between China and Madagascar uncovers an alternative approach to environmentalism that disrupts Western models. Rosewood is the world’s most trafficked endangered species by value, accounting for larger outlays than ivory, rhino horn, and big cats put together. Nearly all rosewood logs are sent to China, fueling a $26 billion market for classically styled furniture. Vast expeditions across Asia and Africa search for the majestic timber, and legions of Chinese ships sail for Madagascar, where rosewood is purchased straight from the forest. The international response has been to interdict the trade, but in this incisive account Annah Lake Zhu suggests that environmentalists have misunderstood both the intent and the effect of China’s appetite for rosewood, causing social and ecological damage in the process. For one thing, Chinese consumers are understandably seeking to reclaim their cultural heritage, restoring a centuries-old tradition of home furnishing that the Cultural Revolution had condemned. In addition, Chinese firms are investing in environmental preservation. Far from simply exploiting the tree, businesses are carefully managing valuable forests and experimenting with extensive new plantings. This sustainable-use paradigm differs dramatically from the conservation norms preferred by Western-dominated NGOs, whose trade bans have prompted speculation and high prices, even encouraging criminal activity. Meanwhile, attempts to arm conservation task forces—militias meant to guard the forests—have backfired. Drawing on years of fieldwork in China and Madagascar, Rosewood upends the pieties of the global aid industry. Zhu offers a rigorous look at what environmentalism and biodiversity protection might look like in a world no longer dominated by the West.
