"Advances in Cancer Research" provides invaluable information on
the exciting and fast-moving field of cancer research. This
thematic volume looks at "Histone Deacetylase Inhibitors as Cancer
Therapeutics."
Described as the earliest, simplest life forms, with unlimited metabolic versatility, bacteria are ideally suited to answer some very fundamental questions on life and its processes. They have been employed in almost all fields of biological studies, including Genetics. The whole edifice of science of Genetics centers around three processes: the generation, expression, and transmission of biological variation, and bacteria offer immediate advantages in studying all the three aspects of heredity. Being haploid and structurally simple, it becomes easy to isolate mutations of various kinds and relate them to a function. The availability of such mutants and their detailed genetic and biochemical analyses lead to a gamut of information on gene expression and its regulation. While studying the transmission of biological variation, it is clear that unlike their eukaryotic counterpart, a more genetic approach needs to be employed. Transmission of genetic information in most eukaryotic organisms rests on sexual reproduction that allows the generation of genetically variable offspring through the process of gene recombination. Even though bacteria show an apparent preference for asexual reproduction, they too have evolved mechanisms to trade their genetic material. In fact, bacteria not only could acquire many genes from close relatives, but also from entirely distant members through the process of horizontal gene transfer. Their success story of long evolutionary existence will stand testimony to these mechanisms. While teaching a course on Microbial Genetics to the post-graduate students at Delhi University, it was realized that a book devoted to bacterial genetics may be very handy to the students, researchers, and teachers alike. A strong foundation in genetics also helps in comprehending more modern concepts of molecular biology and recombinant DNA technology, always a favorite with the students and researchers. Planning the format of the book, emphasis has been laid on the generation and transmission of biological variability. The omission of expression part is indeed intentional because lots of information is available on this aspect in any modern biology book. The contents are spread over seven chapters and the text is supported with figures/tables wherever possible. The endeavor has been to induce the readers to appreciate the strength of bacterial genetics and realize the contribution of these tiny organisms to the growth of biological sciences as a whole and genetics in particular.
In the last 3 decades, stem cells have greatly impacted the scientific and lay communities, providing huge advances in the treatment of devastating human diseases, including myocardial infarction, diabetes, muscular dystrophy, cystic fibrosis, cirrhosis, and osteoporosis. Alongside debates of induced pluripotent stem cells and embryonic stem cells has been the discovery of adult stem cells in many different tissues. While these organ resident or progenitor stem cells offer prospects to contribute to tissue regeneration, they also present challenges because of the complexity of organ structures. This book will present the main findings to date and the
important factors to be considered when considering resident stem
cells in regenerative therapies. Chapters on cardiac, brain,
neural, liver, kidney, skeletal muscle, bone, pancreatic, skin, and
lung resident stem cells will assist in defining the level of
success that has been achieved and the direction for the road
ahead. With contributions from leading laboratories, open questions
related to resident stem cells and regenerative therapies will also
be presented for debate. Highlights basic research in tissue specific stem cells, experiments with animal models and clinical trials that are transforming the field of regeneration. Provides a clear understanding of endogenous stem cells, their role in current regenerative therapies, and prospects for future research Reports on the main-stream clinical approaches and in vivo experiments published in primary literature to help categorizes the advances in various aspects of regenerative therapy and illustrate opportunities for clinical applications "
This book explores the socio-political implications of human heredity from the second half of the nineteenth century to the present postgenomic moment. It addresses three main phases in the politicization of heredity: the peak of radical eugenics (1900-1945), characterized by an aggressive ethos of supporting the transformation of human society via biological knowledge; the repositioning, after 1945, of biological thinking into a liberal-democratic, human rights framework; and the present postgenomic crisis in which the genome can no longer be understood as insulated from environmental signals. In Political Biology, Maurizio Meloni argues that thanks to the ascendancy of epigenetics we may be witnessing a return to soft heredity - the idea that these signals can cause changes in biology that are themselves transferable to succeeding generations. This book will be of great interest to scholars across science and technology studies, the philosophy and history of science, and political and social theory.

chromatin and has chapters on dynamic mapping of histone-DNA
interactions in nucleosomes by unzipping single molecules of DNA,
digital DNase technology, and genome-wide analysis of chromatin
transition.
Despite the popular perception that genetic explanations of the causes of crime are new, biological determinism dates back to the birth of criminology, and the ideas of the man widely regarded as its founder, Cesare Lombroso. His 1876 work, DEGREESICriminal Man DEGREESR, drew on Darwin to propose that most lawbreakers were throwbacks to a more primitive level of human evolution--identifiable by their physical traits, such as small heads, flat noses, large ears, and the like. These born criminals could not escape their biological destiny. The scientific appeal of these theories of criminal anthropology had a powerful and long-lasting impact on criminological theory and practice in contemporary Italy, Europe, and the Western world as a whole, and even today the stereotypes they created resonate in popular culture. But while these ideas had a wide influence, their origins were very much in a specific time and place--the political, economic, and social history of modern Italy. Gibson shows that understanding the development of Lombroso's thinking is much more complicated than merely pinning his ideas onto the left-right political spectrum; he influenced socialists and fascists, lawyers and doctors, policemen and social workers alike. In the end, she argues for a more subtle interpretation of his theories, emphasizing that Lombroso himself acknowledged the multifaceted nature of criminal behavior.

Metagenomics has taken off as one of the major cutting-edge fields of research. The field has broad implications for human health and disease, animal production and environmental health. Metagenomics has opened up a wealth of data, tools, technologies and applications that allow us to access the majority of organisms that we still cannot access in pure culture (an estimated 99% of microbial life). Numerous research groups are developing tools, approaches and applications to deal with this new field, as larger data sets from environments including the human body, the oceans and soils are being generated. See for example the human microbiome initiative (HMP) which has become a world-wide effort and the Global Ocean Sampling (GOS) surveys. The number of publications as measured through PubMed that are focused on metagenomics continues to increase. The field of metagenomics continues to evolve with large common datasets available to the scientific community. A concerted effort is needed to collate all this information in a centralized place. By having all the information in an Encyclopedia form, we have an opportunity to gather seminal contributions from the leaders in the field, and at the same time provide this information to a significant number of junior and senior scientists. It is anticipated that the Encyclopedia will also be used by many other groups including, clinicians, undergraduate and graduate level students, as well as ethical and legal groups associated with or interested in the issues surrounding metagenome science.
Considerable advances have taken place since the initial isolation and characterization of human embryonic stem (HES) cells; however, significant challenges remain before their potential for restoration and regeneration processes in patients can be realized. Understanding the diversity amongst HES cell lines and realizing the ability to isolate lines with robust differentiation potential remain difficult. In the Human Embryonic Stem Cells Handbook, experts in the field provide an assortment of protocols that have been used by various laboratories around the world so as to allow both novices and experienced investigators to compare and contrast different approaches to HES cell isolation and characterization with the hope that, from these protocols, researchers might standardize approaches for HES cell biology. Written in the Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips for troubleshooting and avoiding known pitfalls. Authoritative and accessible, Human Embryonic Stem Cells Handbook serves as a valuable reference for scientists pursuing this vital field and its enormous potential.
This book provides a premier resource on understanding the ribosome's essential nature and how it interacts with other proteins and nucleic acids to control protein synthesis.

The difference among pluripotent stem cells, multipotent stem cells, and unipotent stem cells is pointed out. Vast therapeutic applications of the following specific stem cells in disease and tissue injury are discussed: human embryonic stem cells, human mesenchymal stem cells, germ cell-derived pluripotent stem cells, induced pluripotent stem cells, human umbilical cord blood-derived stem cells, breast tumor stem cells,and hematopoietic stem cells. Because of the potential of human embryonic stem cells to produce unlimited quantities of any human cell type, considerable focus is placed on their therapeutic potential. Because of their pluripotency, these cells have been used in various applications such as tissue engineering, regenerative medicine, pharmacological and toxicological studies, and fundamental studies of cell differentiation. The formation of embryoid bodies, which are three-dimensional aggregates of embryonic stem cells, is explained as this is the first step in cell differentiation. Such embryoid body culture has been widely used as a trigger for the in vitro differentiation of embryonic stem cells. The basic capacity of self-renewal of human embryogenic stem cells is explained. The role of TGF-beta in the propagation of human embryonic stem cells is discussed. The differentiation of human embryonic stem cells into neurons, hepatocytes, cardiomyocytes, and retinal cells is fully explained. Donor policies for hematopoietic stem cells are also explained.
The fourth edition of this classic text continues to provide the basis for understanding genetic principles behind quantitative differences, and extends these concepts to the segregation of genes that cause genetic variation in quantitative traits. The authors explain key techniques and methods.
JAK tyrosine kinases and STAT transcription factors constitute a signaling pathway, which is activated by cytokines. By activating gene transcription it regulates essential biological responses to environmental cues. The Jak-Stat pathway is involved in the regulation of cell development, differentiation, proliferation and apoptosis. Improper function may contribute to hematopoietic malignancies and cancer. This book provides comprehensive insights into the latest basic and clinical developments in the field. The first part reviews recent findings and new technologies pertaining to basics of Jak-Stat function. The second part describes the evolution of Jak-Stat signaling and the role of the pathway in invertebrate organisms. The third part focuses on Jak-Stat signaling in hematopoietic cells under both physiological and pathophysiological conditions. Finally, chapters in the fourth section describe the relationship of Jak-Stat signaling to various states of disease, particularly infection, leukemias and solid cancers. The book is intended for all scientists in molecular biology, biochemistry and cell biology dealing with biomedical issues. |
