Oskar The Pole

This ebook also includes an extract from Judy Nunn's new novel, Sanctuary. For eight years now Oskar the Pole has been a widower. As a homeless vagrant, pushing a supermarket trolley through the streets of life, he cuts a lonely figure. But Oskar has a talent. He can play chess, and he can play it well. Every afternoon, at the giant chessboard in the park, Oskar becomes a star, a master, the undefeated champion . . . The second of Judy Nunn’s captivating short stories featuring the homeless men and women who gather around the plastic bins near the docks, is a heart-warming tale of friendship and community.

This book combines the most recent knowledge on the maternal, i.e. oocyte/egg-specific, molecules and processes. The volume covers the most recent advances in a plethora of subjects such as: maternal transfer of immunity, localized RNAs functions and mechanisms of RNA localization, transcriptional repression of maternal messages, maternal inheritance and maternal role of CRISPR/Cas9-based genome editing, chromatin remodeling and epigenetic modifications, maternal function of nucleosomes, maternal mitochondria and energy supply, role of bacterial symbionts and their maternal transmission, acquisition of oocyte polarity and evolution of maternal effect genes, germ plasm and oosome origin and functions, mechanisms of oocyte activation and soma germ cells communication. Currently, no other book on the market combines such a comprehensive list of subjects in one volume. Moreover, the information provided is a cross-section through oocytes from various invertebrate and vertebrate species, which is another unique feature of this book. The readers, therefore, get a completely new and invaluable perspective on all covered subjects.

Coverage of the field in Instant Notes in Developmental Biology is current and focuses largely on the principles of embryonic development. It is designed to provide a clear summary of the principles of developmental biology in a compact and easily manageable structure.

In 2016 Current Topics in Developmental Biology (CTDB) will celebrate its 50th or “golden anniversary. To commemorate the founding of CTDB by Aron Moscona (1921-2009) and Alberto Monroy (1913-1986) in 1966, a two-volume set of CTDB (volumes 116 and 117), entitled Essays on Development, will be published by Academic Press/Elsevier in early 2016. The volumes are edited by Paul M. Wassarman, series editor of CTDB, and include contributions from dozens of outstanding developmental biologists from around the world. Overall, the essays provide critical reviews and discussion of developmental processes for a variety of model organisms. Many essays relate the history of a particular area of research, others personal experiences in research, and some are quite philosophical. Essays on Development provides a window onto the rich landscape of contemporary research in developmental biology and should be useful to both students and investigators for years to come.

Wassarman

International Review of Cytology presents current advances and comprehensive reviews in cell biology, both plant and animal. Articles address structure and control of gene expression, nucleocytoplasmic interactions, control of cell development and differentiation, and cell transformation and growth. Authored by some of the foremost scientists in the field, each volume provides up-to-date information and directions for future research. This volume brings together current information on the localization and roles of RNAs in cell-lineage determination and subsequent patterning in embryonic development. Guest co-editor Lawrence Etkin is one of the leading researchers in molecular genetics of Xenopus. Key Features * A number of important concepts are discussed, including: * How polarity is established during oogenesis * How germ cell determinants become organized in the establishment of the germ cell lineage * Different strategies used by organisms to establish the germ cell lineage * Similarities and differences between the mechanisms used in embryonic patterning * The mechanisms and machinery by which molecules such as RNA become asymmetrically segregated * The use of similar signaling pathways in patterning of the dorsal-ventral and right-left asymmetries, embryonic germ layers, limb, and nervous system * The link between fundamental biological processes such as RNA translation and localization in the regulation of axis specification

This book focuses on the development and biology of germ cell and is edited by Ahmed RG, associate professor and Doctor of Developmental and Experimental Biology, Division of Anatomy and Embryology, Zoology Department, Faculty of Science, Beni-Suef University, Egypt. While many articles have appeared in journals on germ cell, this book provides you with a rare treat - an extensive and intensive study on it. It is one of a kind, offering important and valuable information about the biology of germ cell. This book covers the specification, regulation, and reprogramming of germ cell and germ line stem cells. This book provides important information about the new insight into germ cell signaling and the genotoxic in vitro studies in testicular germ cells. This book offers significant results about the origin, specification, and development of the female germ line in placental mammals and the germ cell tumors and their association with pregnancy.

This book describes human development including sexual reproduction and stem cell research with the development of model organisms that are accessible to genetic and experimental analysis in readily understandable texts and 315 multi-colored graphics. The introductory account of model organisms selected from the entire animal kingdom presents general principles, which are then outlined in subsequent chapters devoted to, for example, sexual development; genes controlling development and their contemporary molecular-analysis methods; production of clones and transgenic animals; development of the nervous and circulatory systems; regenerative medicine and ageing. Finally the evolution of developmental toolkits and novelties is discussed including the genetic basis of the enlargement of the human forebrain. Separate boxes are devoted to controversial questions such as the benefits and problems of prenatal diagnostics or the construction of ancient body plans.

All the key principles of developmental biology that students need to know, which are underpinned throughout by experimental evidence, and an exploration of the molecular basis of the subject.
