Leishmania is a vector-borne pathogenic parasite found in 88 countries worldwide and is the causative agent of leishmaniasis. The different Leishmania species infect macrophages and dendritic cells of the host immune system, causing symptoms that range from disfiguring cutaneous and mucocutaneous lesions, widespread destruction of mucous membranes, or visceral disease affecting the haemopoetic organs. The recent publication of the complete genome sequences of three different Leishmania species provides new insights into this leading pathogen and presents scientists with an exciting resource to improve the understanding of its complex molecular and cellular biology. In this book, internationally recognized Leishmania experts critically review the most important aspects of current Leishmania research, providing the first coherent picture of the organism's molecular and cellular biology since the publication of the genome sequence. Chapters are written from a molecular and genomic perspective and discuss in depth Leishmania-specific aspects of trypanosomatid biology and pathology. Topics include: diagnosis and epidemiology, genome structure and content, regulation of gene expression, the Leishmania proteome, the Leishmania metabolome, Leishmania differentiation, interaction with the sand fly vector, drug discovery, drug resistance, and much more. This will be essential reading for all researchers working with Leishmania, trypanosomes, and protozoa; and is recommended for all biology and medical libraries.

The Genetical Theory of Natural Selection by R.A. Fisher (1930) dictated that sexual dimorphisms may depend upon a single medelian factor. This could be true for some species but his suggestion could not take off the ground as gender in Drosophila is determined by the number of X chromosomes. Technical advances in molecular biology have revived the initial thinking of Fisher and dictate that TDF or SRY genes in humans or Tdy in mice are sex determining genes. The fortuitous findings of XX males and XY female, which are generally termed sex reversal phenomenon, are quite bewildering traits that have caused much amazement concerning the pairing mechanism(s) of the pseudoautosomal regions of human X and Y chromosomes at meiosis. These findings have opened new avenues to explore further the genetic basis of sex determination at the single gene level.
The aim of the fourth volume, titled Genetics of Sex Determination is to reflect on the latest advances and future investigative directions, encompassing 10 chapters. Commissioned several distinguished scientists, all pre-eminent authorities in each field to shed their thoughts concisely but epitomise their chapters with an extended bibliography. Obviously, during the past 60 years, the metoric advances are voluminous and to cover every account of genes, chromosomes, and sex in a single volume format would be a herculean task. Therefore, a few specific topics are chosen, which may be of great interest to scientists and clinicians. The seasoned scientists who love to inquire about the role of genes in sex determination should find the original work of these notable contributors very enlightening. This volume is intended for advanced students who want to keep abreast as well as for those who indulge in the search for genes of sex determination.

Bioinformatics is an integrative field of computer science, genetics, genomics, proteomics, and statistics, which has undoubtedly revolutionized the study of biology and medicine in past decades. It mainly assists in modeling, predicting and interpreting large multidimensional biological data by utilizing advanced computational methods. Despite its enormous potential, bioinformatics is not widely integrated into the academic curriculum as most life science students and researchers are still not equipped with the necessary knowledge to take advantage of this powerful tool. Hence, the primary purpose of our book is to supplement this unmet need by providing an easily accessible platform for students and researchers starting their career in life sciences. This book aims to avoid sophisticated computational algorithms and programming. Instead, it will mostly focus on simple DIY analysis and interpretation of biological data with personal computers. Our belief is that once the beginners acquire these basic skillsets, they will be able to handle most of the bioinformatics tools for their research work and to better understand their experimental outcomes. The third volume is titled In Silico Life Sciences: Agriculture. It focuses on plant genetic, genomic, transcriptomic, proteomic and metabolomics data. Using examples of new crop diseases-emergence, crop productivity and biotic/abiotic stress tolerance, this book illustrates how bioinformatics can be an integral components of modern day plant science research.

This compendium presents some of the major applications of neutron scattering techniques to problems in biology. It is a record of the papers presented at the Neutrons in Biology Conference, the third in an occasional series held to highlight progress in the field and to provide a focus for future direction. The strength ofthe neutron scattering technique remains principally in the manipula tion of scattering density through hydrogen and deuterium atoms. The development ofad vanced detectors, innovative instrument and beamline components, and sophisticated data acquisition systems through the 1970s and early 1980s provided a sound foundation for the technique. With continued development, some of the exotic and expensive equipment has become affordable by the medium-sized facilities, thereby broadening the user base considerably. Despite problems with the major neutron sources in the late 1980s and early 1990s, some spectacular results have been achieved. Whilst the high and medium flux beam reac tors will continue to make a major impact in the field, the results from the first experi ments, and the planned developments on spallation neutron sources, clearly indicate that the technique has enormous potential.

In Human Cloning a panel of distinguished philosophers, medical ethicists, religious thinkers, and social critics tackle the thorny problems raised by the now real possibility of human cloning. In their wide ranging reviews, the distinguished contributors critically examine the major arguments for and against human cloning, probe the implications of such a procedure for society, and critically evaluate the "Report and Recommendations of the National Bioethics Advisory Commission." The debate includes both religious and secular arguments, as well as an outline of the history of the cloning debate and a discussion of human cloning's impact on our sense of self and our beliefs about the meaning of life.

Few would dispute the truth of the statement People are Different', but there is much controversy over why. This book authoritatively explains the methods used to understand human variation, and extends them far beyond the primary nature or nurture' question. After chapters on basic statistics, biometrical genetics, matrix algebra and path analysis, there is a state-of-the-art account of how to fit genetic models using the LISREL package. The authors explain not only the assumptions of the twin method, but how to test them. The elementary model is expanded to cover sex limitation, sibling interaction, multivariate and longitudinal data, observer ratings, and twin-family studies. Throughout, the methods are illustrated by applications to diverse areas such as obesity, major depression, alcohol comsumption, delinquency, allergies, and common fears.

Splicing of primary RNA transcript is a quasi-systematic step of gene expression in higher organisms. This is the first book to highlight the medical implications, i.e. diseases, caused by alternative splicing. Alternative splicing not only vastly increases protein diversity but also offers numerous opportunities for aberrant splicing events with pathological consequences. The book also outlines possible targets for therapy.

The in situ hybridization and PCR technologies are now well-established molecular techniques for studying chromosomal aneuploidy and rearran- ments, gene localization and expression, and genomic organization. Over the last decade, we have seen increasing applications in these fields. By combining the high sensitivity of the PCR reaction and the cytological localization of target sequences, both PRINS and in situ PCR techniques have provided highly powerful complements to FISH for in situ cellular and molecular investigations. Both these approaches have several advantages in terms of sensitivity and specificity, owing to the use of primers and to the fast kinetics of annealing and elongation reactions in situ. In the first edition of PRINS and In Situ PCR Protocols edited by John R. Gosden, experts in the field presented in detail a variety of applications of PRINS and in situ PCR techniques, in a wide range of clinical conditions. Since the publication of this successful reference book, there have been s- nificant improvements in in situ detection techniques. This completely revised and updated second edition presents a compreh- sive selection of new procedures developed in the field of PRINS and in situ PCR technologies. The book has two sections. Part I, Basic Methodology, contains chapters that provide useful protocols for many variations of PRINS and in situ PCR, including a new fast multicolor PRINS method, and protocols for PRINS detection of unique sequences in situ.

A one-stop resource that provides the most frequently needed information on the human genome What are the genes that manke-up the human genome, what do the genes do when they are acting properly, and what happens when these genes are damaged? Designed for today's reader who demands quick answers to a wide range of questions, The Human Genome Sourcebook is intended to offer the non-specialist an accessible but detailed guide to the genome. The information it provides is given context: namely, the basic scientific principles of genome research, the new knowledge unearthed or created by this research, and the social and ethical implications of this knowledge. The Human Genome Sourcebook is organized in several sections to simplify the location of pertinent information: an extensive section that comprises an in-depth catalogue of human genes listed according to the roles they play in life; a chapter that relates genetic diseases to the specific genes that cause the disease; a detailed glossary giving readers a deeper understanding of genetic terms and concepts; an overview or roadmap of the physical layout of the genome sections. provides both information as well as the tools necessary to access that information.. Provides in-depth information on the relationships between our genes and all aspects of our daily lives. Addresses health issues that are related to genetic abnormalities

Cells in the developing embryo depend on signals from the extracellular environment to help guide their differentiation. An important mediator in this process is the extracellular matrix -- secreted macromolecules that interact to form large protein networks outside the cell. During development, the extracellular matrix serves to separate adjacent cell groups, participates in establishing morphogenic gradients, and, through its ability to interact directly will cell-surface receptors, provides developmental clocks and positional information. This volume discusses how the extracellular matrix influences fundamental developmental processes and how model systems can be used to elucidate ECM function. The topics addressed range from how ECM influences early development as well as repair processes in the adult that recapitulate developmental pathways. The series Biology of Extracellular Matrix is published in collaboration with the American Society for Matrix Biology.

Although they comprise one of the three fundamental branches of life, it was only the last decade that Archaea were formally recognized as a group alongside Eukaryotes and Bacteria. Bacteria-like in that they are single celled organisms that lack a nucleus and intracellular organelles, the Arachaea also share a large gene set typical of eukaryotes, for making and repairing DNA, RNA and protien. More surprisingly, they only inhabit environments typical of the extremes of early earth--hot springs, thermal ocean vents, saline lake, or oxygen deficient sediments. A breakpoint on the common evolutionary path, it is evident that the Archaea diverged early in the history of life, establishing thier importance in evolutionary sciences. "Archaea: Ancient Microbes, Extreme Environments, and the Origin of Life" tells this evolving story, furthering our understanding of the microbe commonalities, and providing for evolutionary justification in the use of archaea as mechanistic model systems.

This volume brings together the disciplines of plant and animal genome research, and serves as an opportunity for scientists from both fields to compare results, problems and prospects.

The potential now exists in many experimental systems to transfer a cloned, modified gene back into the genome of the host organism. In the ideal situation, the cloned gene is returned to its homologous location in the genome and becomes inserted at the target locus. This process is a controlled means for the repair of DNA damage and ensures accurate chromosome disjunction during meiosis. The paradigm for thinking about the mechanism of this p- cess has emerged primarily from two sources: (1) The principles of reaction mechanics have come from detailed biochemical analyses of the RecA protein purified from Escherichia coli; and (2) the principles of information transfer have been derived from genetic studies carried out in bacteriophage and fungi. A compelling picture of the process of homologous pairing and DNA strand exchange has been influential in directing investigators interested in gene t- geting experiments. The ability to find and pair homologous DNA molecules enables ac- rate gene targeting and is the central phenomenon underlying genetic recombi- tion. Biochemically, the overall process can be thought of as a series of steps in a reaction pathway whereby DNA molecules are brought into homologous register, the four-stranded Holliday structure intermediate is formed, hete- duplex DNA is extended, and DNA strands are exchanged. Not much is known about the biochemical pathway leading to homologous recombination in euka- otes.

Neglected and Underutilized Crops: Future Smart Food explores future food crops with climate resilience potential. Sections cover their botany, nutritional significance, global distribution, production technology, and tolerance to biotic and abiotic stresses of neglected and underutilized crops. By simply changing species in a crop rotation system, the cycle of some pests and diseases is disrupted and probabilities of infestations are reduced. Finally, the book provides case studies that highlight where the adaptation of crops to local environments, especially with regard to climate change, have been successful. These crops can help make agricultural production systems more resilient to climate change. Although a few books on neglected and underutilized crops are available, this comprehensive book covers the full scope of crop husbandry, nutritional significance and global distribution.

Genetic variability is an important parameter for plant breeders in any con ventional crop improvement programme. Very often the desired variation is un available in the right combination, or simply does not exist at all. However, plant breeders have successfully recombined the desired genes from cultivated crop gerrnplasm and related wild species by sexual hybridization, and have been able to develop new cultivars with desirable agronomie traits, such as high yield, disease, pest, and drought resistance. So far, conventional breeding methods have managed to feed the world's ever-growing population. Continued population growth, no further scope of expanding arable land, soil degradation, environ mental pollution and global warrning are causes of concern to plant biologists and planners. Plant breeders are under continuous pressure to improve and develop new cultivars for sustainable food production. However, it takes several years to develop a new cultivar. Therefore, they have to look for new technologies, which could be combined with conventional methods to create more genetic variability, and reduce the time in developing new cultivars, with early-maturity, and improved yield. The first report on induced mutation of a gene by HJ. Muller in 1927 was a major mi1estone in enhancing variation, and also indicated the potential applica tions of mutagenesis in plant improvement. Radiation sources, such as X-rays, gamma rays and fast neutrons, and chemical mutagens (e. g., ethyl methane sulphonate) have been widely used to induce mutations."

When the late Professor C. D. Darlington founded what developed into the International Chromosome Conferences in Oxford in 1964, he was concerned that scientists who worked on different aspects of chromosomes, or who studied them in different ways, should have the opportunity of "discussing the fundamental problems of chromosomes with one another". The fact that well over 300 scientists with a wide variety of interests came to Edinburgh in August 1992 for the 11th International Chromosome Conference shows that there is still the same need, and also the desire among chromosomologists to have such discussions. The present volume contains almost all the invited contributions, and attests to the diversity of approaches and applications in chromosomal studies. A few years ago it may have seemed to some that chromosome studies were being superseded by molecular biology, but the molecular biologists have now realized that they need to know about chromosomes, and indeed an important, if ill-defined discipline of 'molecular cytogenetics' has grown up in recent years. We are pleased that in planning the Conference and this book, so much of the work presented is at the interface between cytogenetics and molecular biology. This will surely continue in the future, as boundaries between disciplines are largely artificial, and each has much to learn from the others.

As a college student, Werner Maas took a course in genetics in 1941 and wondered why so little was said about the biochemical action of genes in controlling the specific function of an organism. Just at that time, biochemists and geneticists began to investigate jointly the basis of gene action, especially in microorganisms. Thus, Maas was able to witness firsthand the spectacular developments that led in the next twenty-five years to a clear picture of the action of genes. The history of these remarkable discoveries is the core of this book. After 1965, building on insights gained from the work with microorganisms, studies of gene action turned to animals and plants and concentrated on processes not present in microorganisms, such as embryonic development, the role of genes in diseases, and the function of the nervous system. Because of the rapidity of technical advances made in handling genes, it has been possible to learn much about these complex processes. The last part of the book deals with these developments, which are ongoing parts of the history of gene action.

This manual offers detailed protocols for fluorescence in situ hybridization (FISH) and comparative genomic hybridization approaches, which have been successfully used to study various aspects of genomic behavior and alterations. Methods using different probe and cell types, tissues and organisms, such as mammalians, fish, amphibians (including lampbrush-chromosomes), insects, plants and microorganisms are described in 57 chapters. In addition to multicolor FISH procedures and special applications such as the characterization of marker chromosomes, breakpoints, cryptic aberrations, nuclear architectures and epigenetic changes, as well as comparative genomic hybridization studies, this 2nd edition describes how FISH can be combined with other techniques. The latter include immunostaining, electron microscopy, single cell electrophoresis and microdissection. This well-received application guide provides essential protocols for beginning FISHers and FISH experts alike working in the fields of human genetics, microbiology, animal and plant sciences.

The intersection of race, ethnicity and genomics has recently been a focus of debate and concern. The key areas of debate are pharmacogenomics and, to a lesser extent, racial profiling in the criminal justice system. The former poses the question as to whether certain "races" are genetically predisposed towards given diseases and whether they metabolize drugs differently; with the latter debating whether DNA analyses accurately identify the "race" of an individual. This book takes a different approach, while acknowledging the importance of these debates and their role in shaping what the issues are perceived to be in thinking about the intersection of race, ethnicity and genomics. We are interested in exploring the interconnections between race, ethnicity and nation and kinship, always bearing in mind that kinship, as a domain of human experience and a field of social study, has been reshaped by the genomic and biotechnological revolution. Peter Wade is Professor of Social Anthropology at the University of Manchester. His publications include Blackness and Race Mixture (1993), Race and Ethnicity in Latin America (1997), Music, Race and Nation: Musica Tropical in Colombia (2000), Race, Nature and Culture: An Anthropological Perspective (2002). His current research focuses on issues of racial identity, embodiment and new genetic and information technologies.
