Sperm-mediated gene transfer (SMGT) represents a novel set of technologies for animal (or in the future, human) genetic modification using the sperm as a vector, as opposed to more traditional established routes such as fertilized eggs or embryonic stem cells. Studies of sperm-mediated gene transfer (SMGT) indicate that sperm cells possess the ability to be utilized as carriers of exogenous genetic sequences, offering the potential of a novel cost-effective route for germline genetic modification. The fate of transgenes borne by sperm cells has been inconsistent, and analysis of offspring from SMGT experiments has shown a mixed picture in terms of genomic integration of the transgene, suggesting an episomal mode of inheritance. Various distinct steps in transgene uptake by the sperm cell have been described or proposed, including a model based upon endogenous reverse transcriptase activity. Although mature sperm cells are naturally protected against uptake of foreign nucleic acid molecules, certain environmental conditions, for example at key times within the reproductive tract, may reduce this protection, suggesting that SMGT may occasionally take place in nature. If correct, this carries profound implications for evolution and human genetic health. This e-book brings together theoretical and empirical reviews from experts in SMGT, providing comprehensive coverage of the major trends, developments and controversies in this novel field. This e-book is intended as a reference for professional researchers in the field of animal genetic modification (transgenesis) as well as teachers, scientists and physicians interested in medical genetics in general and gene therapy in particular.

Recent advances in the fields of genomics and bioinformatics have made it increasingly clear that genetic sequence alone cannot explain how the genome regulates the development and function of complex multicellular organisms both in health and disease. This inference has led to the expansion of epigenetics as a discipline. Epigenetics refers to the way in which the environment in the wide sense participates in the regulation of gene expression. Several studies show that the well-known beneficial role of a healthy lifestyle over a number of pathologies or as a pre-emptive therapy is at least in part exerted through epigenetic mechanisms, thus giving rise to a new paradigm of preventive medicine based on the concept of genetic plasticity. In Epigenetics of Lifestyle, several contributors provide a comprehensive view of how various facets of lifestyle, including nutrition, exercise, stress, addiction or social interactions, affect chromatin (the combination of DNA and proteins that make up the contents of a cell nucleus) - resulting in profound and long-lasting changes in gene function. In summary, Epigenetics of Lifestyle is a fresh approach towards epigenetics and presents the reader with significant research findings in epigenetics and lifestyle studies. This volume is a simplified source of information for both undergraduate and working professionals interested in lifestyle medicine and life sciences in general.

Rhizobia are composed of specific groups of bacteria that have the ability to induce symbiotic nitrogen-fixing nodules on the roots or stems of leguminous plants. Rhizobia have attracted a great attention for more than 4 decades because of their enormous agricultural and economic value in sustainable agriculture. Up to the present time, many legumes have been found to be nodulated by several rhizobial species in diverse taxonomic groups. An assessment of rhizobial diversity provides pivotal information in understanding the horizontal gene transfer among bacterial genera and species, the bacterial evolution and the symbiotic effectiveness. The classification of rhizobia is becoming increasingly complex and is revised periodically because of new findings that propose new genera and new species. Phenotypic and Genotypic Diversity of Rhizobia presents the application of conventional and molecular analyses, including numerical analysis, enzyme patterns, serological studies, plasmid profile, polymerase chain reaction (PCR)-fingerprinting, amplified fragment length polymorphism (AFLP), restriction fragment length polymorphism (RFLP), PCR-RFLP and sequence-based methods, to the examination of rhizobial diversity. Principles of these techniques, the resolving power, the advantage and the limitation of these techniques are evaluated. Current taxonomy of rhizobia classifies them into 17 genera and 118 species. The book explains background knowledge about rhizobia and follows this up with a broad perspective on rhizobial diversity, information on characteristics specific to each group of rhizobia, the relationship among rhizobial groups as well as genetic factors contributed to rhizobial diversity. Contemporary methods for examination of rhizobial diversity are also suggested and discussed. Readers of this e-book will find updated information on key concepts in classification and taxonomy of rhizobia, the categories and techniques used to examine the phenotypic and genotypic diversity of rhizobia (including numerical analysis, enzyme patterns, serological study, plasmid profile, polymerase chain reaction (PCR)-fingerprinting, amplified fragment length polymorphism (AFLP), restriction fragment length polymorphism (RFLP), PCR-RFLP and sequence analysis).

A major goal of integrative research is understanding regulatory networks to such an extent as to allow researchers to model developmental and stress responses. Regulatory networks of living systems include complex and vast interactions between proteins, metabolites, RNA, various signaling molecules and DNA. One aspect of systems biology is understanding the dynamics of protein-DNA interactions affecting gene expression that are caused by transcription factors (TFs) and chromatin remodeling factors. This e-book provides a resource for summarizing current knowledge eukaryotic transcription and explores cis-elements and methods for their analysis, prediction and discovery. The book also presents an overview of exploring gene regulatory networks, chromatin, and miRNAs. Information about state-of-the-art techniques for the determination of TF - cis-element interactions in vivo and in silico give cutting edge insights on how genomic-scale research is being approached. The Analysis of Regulatory DNA provides readers with both the necessary background knowledge and provocative, up-to-date insights aimed at sparking new and vibrant experimental designs for understanding and predicting cis-elements in the eukaryotic genome.

Consanguineous marriages have been practiced for hundreds of years, predominantly by Moslems. Although it is generally accepted among communities that the social advantages outweigh other, the rate of congenital malformations and genetic diseases among the offspring borne of consanguineous marriages is higher and an increase in sterility, rates of abortions, stillbirths and neonatal deaths has been suggested by some researchers. These problems result in a substantial economic burden within the communities involved in the practice. Strategies for reducing the frequency of consanguineous marriages include expansion of educational programs, promotion of genetic testing services, and research to identify the genes responsible for genetic defects. Nowadays, with the migration of large numbers of Moslems towards Western countries, consanguinity is becoming a practical issue in places where it was barely known, previously. This eBook serves as a guide for health care workers and counselors of the phenomenon and its associated problems. This eBook begins with an introduction of the topic from a social, legal and biological perspective. It then progresses to research about associated genetic disorders, reproductive and social awareness issues through the proceeding chapters. The eBook concludes with 2 chapters exploring strategies to counter the effects of consanguinity within the general population.

RNA interference (RNAi) is a biological process in which small nucleotide sequences destroy specific mRNA molecules and, therefore, interrupt genetic expression. RNAi has rapidly developed into a widely used technique in biotechnology, experimental biology, genomics and medicine. Frontiers in RNAi is a collection of research articles covering the applications of RNAi principles and technologies and has been compiled by members of the RNAi Global Initiative, a collection of academic and industrial groups with extensive experience in genome-wide RNAi screening. Chapters included in the first volume touch on some of the recent advances in RNAi technology (i.e., applications to 3D cell culture, drug repurposing, and bioproduction) and provide guidance on how to address the continued challenges associated with off-target effects, database structuring, and pooled shRNA screens.

This volume summarizes the history and findings of the First Mariners Project, which the author, Robert G. Bednarik, commenced in 1996 in order to explore the Ice Age origins of seafaring. This is the largest archaeological replication project ever undertaken with several hundred people involved in the construction of eight primitive vessels with stone tools under scientifically controlled conditions, six of them sailing. Four bamboo rafts have succeeded in accomplishing the historically documented crossings they sought to replicate. One of the successful experiments, a 1000 kilometer journey to Australia in 1998, attempted to recreate the first human arrival in Australia, probably around 60,000 years ago. Other voyages attempted to address the much earlier sea crossings documented to have taken place in the islands of Indonesia, the earliest of which may have occurred nearly a million years ago. These experiments have also featured in BBC and National Geographic documentaries. The First Mariners comprehensively describes the archaeological background and relevant issues of the project and features an extensive pictorial record, of both the experiments and the archaeological basis of this research – giving a unique experience to readers interested in understanding the earliest marine adventurers from a historical and technical perspective.
