MicroRNAs (miRNAs), endogenous noncoding regulatory mRNAs of around 22-nucleotides long, have rapidly emerged as one of the key governors of the gene expression regulatory program in cells of varying species, with ever-increasing implications in the control of the fundamental biological processes and in the pathogenesis of adult humans. The exciting findings in this field have inspired us with a premise and a promise that miRNAs will ultimately be taken to the heart for therapy of human disease. While miRNAs have been considered potential therapeutic targets for disease treatment, it...

"Alginates: Biology and Applications" provides an overview of the state of art of alginate material properties, genetics and the molecular mechanisms underlying alginate biosynthesis as well as applications of tailor-made alginates in medicine, food and biotechnology.

Topics treated are: material properties of alginates, alginate production: precursor biosynthesis, polymerization and secretion, bacterial system for alginate uptake and degradation, enzymatic alginate modification, alginate gene regulation, role of alginate in bacterial biofilms, microbial production of alginates:...

Once per life cycle, mitotic nuclear divisions are replaced by meiosis I and II - reducing chromosome number from the diploid level to a haploid genome, reshuffling the homologous chromosomes by their centromeres, and recombining chromosome arms by crossing-over. In animals, including humans, all this happens during the germ cell formation of eggs and sperm. Due to the reign of meiosis, no child is a true genetic copy of either parent. Central to mainstream meiosis, the mechanisms of reciprocal exchange at crossover/chiasma sites stand out as a controlled program of biologically...

Imaging Cellular and Molecular Biological Function provides a unique selection of essays by leading experts, aiming at scientist and student alike who are interested in all aspects of modern imaging, from its application and up-scaling to its development. The chapter content ranges from the basic through to complex overview of method and protocols, and there is also practical and detailed how-to content on important, but rarely addressed topics. This first edition features all-colour-plate chapters.

The philosophy of this volume is to provide student, researcher, PI, professional...

Branching morphogenesis, the creation of branched structures in the body, is a key feature of animal and plant development. This book brings together, for the first time, expert researchers working on a variety of branching systems to present a state-of-the-art view of the mechanisms that control branching morphogenesis. Systems considered range from single cells, to blood vessel and drainage duct systems to entire body plans, and approaches range from observation through experiment to detailed biophysical modelling. The result is an integrated overview of branching.

This book presents some of the most advanced experimental systems in which the role of forces has been dissected. It explores the physical principles accounting for how forces can affect soft matter such as our cells, and presents some of the methods used to measure or assess the role of forces.

The book helps the reader to better understand cytogenetics and the intricacies of the methodology. The different methods of fluorescence in situ hybridization are discussed and the results achieved are presented. The book provides a comprehensive review of basic and applied aspects of cytogenetics and thus is of intense interest to all those interested in chromosomes and their alterations by different types of mutagens, including chemical mutagens and ionizing and nonionizing radiation, with special reference to electromagnetic fields.

Contemporary migration involves a dramatic paradox. Although much of what is considered international or transnational migration today transforms people of a wide range of social standings in the emigration countries into laborers at the bottom social and economic ranks of the immigration countries, millions of individuals worldwide seek to migrate internationally. International Migration, Social Demotion, and Imagined Advancement argues that this paradox cannot be explained for as long as common preconceptions about immigrants economic betterment thwart even questioning why...
