Description : It is instructive to compare the response of biologists to the two themes that comprise the title of this volume. The concept of the cell cycle-in contra distinction to cell division-is a relatively recent one. Nevertheless biologists of all persuasions appreciate and readily agree on the central problems in this area. Issues ranging from mechanisms that initiate and integrate the synthesis of chro mosomal proteins and DNA during S-phase of mitosis to the manner in which assembly of microtubules and their interactions lead to the segregation of metaphase chromosomes are readily followed by botanists and zoologists, as well as by cell and molecular biologists. These problems are crisp and well-defined. The current state of "cell differentiation" stands in sharp contrast. This, one of the oldest problems in experimental biology, almost defies definition today. The difficulties arise not only from a lack of pertinent information on the regulatory mechanisms, but also from conflicting basic concepts in this field. One of the ways in which this situation might be improved would be to find a broader experimental basis, including a better understanding of the relationship between the cell cycle and cell differentiation.

Description : The Cell Cycle: Gene Enzyme Interactions presents the primary regulatory mechanisms of the cell cycle. This book provides theoretical and methodological discussions concerning cell cycles. Organized into 17 chapters, this book begins with an overview of cell evolution and thermodynamics. This text then examines the regulation of initiation of chromosome replication, and the coordination between this event and cell division, in Escherichia coli. Other chapters consider the operon model for the control of genetic expression in bacterial cells, which provides an understanding of the regulatory mechanisms of gene function. This book discusses as well the observations and experiments on the timing of events in the cell cycles of some bacteria and attempts to provide explanations in terms of established control systems. The final chapter deals with DNA markers, which serve as a convenient starting point for exploring the general principles of cell cycle markers. This book is a valuable resource for cell biologists.

Description : This book discusses central concepts and theories in cell biology from the ancient past to the 21st century, based on the premise that understanding the works of scientists like Hooke, Hofmeister, Caspary, Strasburger, Sachs, Schleiden, Schwann, Mendel, Nemec, McClintock, etc. in the context of the latest advances in plant cell biology will help provide valuable new insights. Plants have been an object of study since the roots of the Greek, Chinese and Indian cultures. Since the term “cell” was first coined by Robert Hooke, 350 years ago in Micrographia, the study of plant cell biology has moved ahead at a tremendous pace. The field of cell biology owes its genesis to physics, which through microscopy has been a vital source for piquing scientists’ interest in the biology of the cell. Today, with the technical advances we have made in the field of optics, it is even possible to observe life on a nanoscale. From Hooke’s observations of cells and his inadvertent discovery of the cell wall, we have since moved forward to engineering plants with modified cell walls. Studies on the chloroplast have also gone from Julius von Sachs’ experiments with chloroplast, to using chloroplast engineering to deliver higher crop yields. Similarly, advances in fluorescent microscopy have made it far easier to observe organelles like chloroplast (once studied by Sachs) or actin (observed by Bohumil Nemec). If physics in the form of cell biology has been responsible for one half of this historical development, biochemistry has surely been the other.

Description : Cell Culture and Its Application covers the proceedings of the First International Cell Culture Congress Symposium, which focuses on how cell culture technology could impact on cell biology. The symposium aims to establish facilities for the cultivation of mammalian cells, which in turn would hopefully enhance basic cell biology research. The book is organized into four symposium and workshop sessions, encompassing 45 chapters. The opening chapter recognizes the interlocking relationship of cell culture technology and substantive cell biology. Chapters 2-5 describe the biochemical events that mark the cell cycle, with emphasis on occurrence of histone phosphorylation at each cycle. A discussion on cell differentiation, as a phenomena of interacting, inductive, and inhomogeneous cell populations, is included in these chapters. The second symposium session deals with signs of a revolution in progress in cell culture technology. This includes impact of tissue culture in physiological research course and in understanding of integrated physiology. The last two symposium sessions cover the large-scale production of virus from tissue cultures for cell antigens. An approach to the study of aging using diploid human cells in culture as a model system is also presented. It involves isolation and characterization of HLA antigens from cultured cells and their contribution to the study of disease. A brief discussion on mycoplasma contamination, microplasma-cell-virus interaction, and advantages and limitations of direct and indirect culture for primary isolation and detection of mycoplasma contamination is provided. The book then proceeds by discussing cell differentiation of specific cell or organ, such as testis, sensory cell, hepatocyte, embryonic muscle cell, and brain cortex. The concluding chapters cover nutritional requirements for cell growth, defined culture media for specific cell type, issues and problems related to large-scale cell production, and quality control. Cell biologists and researchers will find this book invaluable.

Description : Biochemical Correlates of Brain Structure and Function deals with the biochemical correlates of brain structure and function, providing some examples of contemporary work interrelating structure with function of the nervous system. The developing brain provides a system for this kind of study, but broad correlates are also drawn between changing biochemistry and increasing physiological activity. This book is organized into nine chapters and begins with an overview of biochemical, morphological, and functional changes in the developing brain, as well as the underlying molecular basis of nerve differentiation and growth of the developing brain. An account of the concept of the cell cycle and its control is also given. The reader is methodically introduced to the properties of the developing retina and its functional biochemistry, with specific reference to the cyclic nucleotides; the use of selective lesioning to delineate GABA-ergic and cholinergic tracts as well as the catecholamine pathways; and cerebral blood flow alteration in concert with mental activity. The remaining chapters explore regions of the brain with altered glucose utilization in response to changes in local functional activity; the physiologically important factors regulating the supply of oxygen and glucose and the relation of metabolic rate to the metabolic state of the brain; and varying aspects of behavioral neurochemistry. This book is intended for chemists and biologists as well as students of biochemistry.

Description : Interest in the cell cycle has grown explosively in recent years as a result of the identification of key cell cycle regulators and their substrates. Aside from enhancing our understanding of normal cellular growth controls, this new knowledge has also becn valuable in elucidating mechanisms of growth deregulation which occur in diseased states, such as cancer and, in some instances, viral or parasitic infections. The Thirteenth Washington International Spring Symposium was organized with the intention of bringing together scientists working on different aspects of the cell cycle. Scientific topics presented ranged from molecular regulators and effectors to mitosis specific changes in cell architecture to the role of the cell cycle in development and disease. The goal of this gathering was to help formulate a more comprehensive and integrated picture of events driving and being driven by the cell cycle, as well as to evaluate the possibilities for clinical application of this knowledge. This symposium, held in Washington, D.C. from May 10-14, 1993, was attended by more than 400 scientists from 20 countries, including many of the scientific leaders in this field. This volume contains most of the papers presented at the seven plenary sessions in addition to selected contributions from a total of nine special oral and poster sessions.

Description : Promoted by advanced experimental techniques for obtaining high-quality data and the steadily accumulating knowledge about the complexity of life, modeling biological systems at multiple interrelated levels of organization attracts more and more attention recently. Current approaches for modeling multilevel systems typically lack an accessible formal modeling language or have major limitations with respect to expressiveness. The aim of this thesis is to provide a comprehensive discussion on associated problems and needs and to propose a concrete solution addressing them. At first, several formal modeling approaches are examined regarding their suitability for describing biological models at multiple organizational levels. Thereby, diverse aspects are taken into account, such as the ability to describe dynamically changing hierarchical model structures and how upward and downward causation between different levels can be expressed. Based on the results of this study, a domain-specific language concept is developed to facilitate multilevel modeling in systems biology. The presented approach combines a rule-based modeling paradigm with dynamically nested model structures, attributed entities, and flexibly constrained reaction rates. Its expressive power, accessibility, and general usefulness for describing biological multilevel models are illustrated with the help of two exemplary case studies.

Description : Written for the undergraduate Cell Biology course, Principles of Cell Biology provides students with an accessible approach to the fundamental concepts of cell biology. The text focuses on the underlying principles that illustrate both how cells function as well as how we study them. It identifies 10 specific principles of Cell Biology, and devotes a separate chapter to illustrate each. The result is a shift away from the traditional focus on technical details and towards a more integrative view of cellular activity that is flexible and can be tailored to suit students with a broad range of backgrounds. An informal, narrative writing style makes even the most complex concepts accessible to students new to the scientific field, including eliminating much of the technical complexity that many students find intimidating. With a wealth of student and instructor ancillary items to round out the course Principles of Cell Biology is the clear choice for your students. Key Features include: -Ten Principle-based chapters build on the foundation laid out in the first four chapters of the text, with heavy emphasis on linking concepts across multiple chapters. -New vocabulary terms are introduced gradually, after the concepts have been established, thereby de-emphasizing memorization of names. -Marginal boxes throughout each chapter include studying tips, clarifications of apparent contradictions, explanations of naming schemes, FAQ, and more. -Analogies are used throughout to clarify concepts and help students retain the material at hand. -Cellular metabolism, a topic that many student struggle with, is introduced and expanded upon in a very accessible way, providing a "big picture" approach to the material. -Provides extensive cross referencing between specific figures and sections of text in different chapters to emphasize that multiple topics are functionally, spatially, and temporally linked. -Concept Check questions, at the end of each section, test comprehension of the section, with answers provided at the end of the chapter. -End-of-chapter questions ask students to integrate material across chapter sections and across different chapters.

Description : The new edition of Bruce Wingerd's The Human Body: Concepts of Anatomy and Physiology helps encourage learning through concept building, and is truly written with the student in mind. Learning Concepts divide each chapter into easily absorbed subunits of information, making learning more achievable. Since students in a one-semester course may have little experience with biological and chemical concepts, giving them tools such as "concept statements," "concept check" questions, and a "concept block study sheet" at the end of each chapter help them relate complex ideas to simple everyday events. The book also has a companion Student Notebook and Study Guide (available separately) that reinvents the traditional study guide by giving students a tool to help grasp information in class and then reinforce learning outside of class. With additional, powerful options like the ADAM Interactive Anatomy Online Student Lab Activity Guide, students have access to learning activities to help them study, understand, and retain critical course information.

Description : Genetic Expression in the Cell Cycle provides an understanding of the molecular mechanisms that govern the expression of genetic information during the cell cycle. The initial five chapters describe the intimate relationships between the supramolecular complexes that form the basic structure of chromatin. Emphasis is placed on the dynamics of cycle-dependent changes in the structural organization of some of these components. Subsequent chapters demonstrate that small nuclear RNAs (SnRNA) are actively involved in gene regulation in eukaryotic cells; discuss the relationship between cell cycle regulation in the yeast Saccharomyces cerevisiae and transcription of ribosomal RNA genes; and describe the use of conditional lethal mutants to study the regulation of the cell cycle of eukaryotic cells. The remaining chapters discuss the concepts and methodologies employed to isolate and study specific cell cycle mutants of S. cerevisiae; the antiproliferative effect of interferon on cultured human fibroblasts; and the role of cell membrane and related subcellular elements in the control of proliferation, differentiation, and cell cycle kinetics.

Description : Over the past two decades there has been an explosion in knowledge about the molecular pathology of human diseases which accelerated with the sequencing of the human genome in 2003. Molecular diagnostics and molecular targeted therapy have contributed to the current concept of personalized patient care that is now routine in many medical centers. As a result, general and subspecialty pathologists, clinical practitioners of all types and radiologists must now have an understanding of the basic concepts of molecular pathology and their role in new diagnostic and therapeutic applications to patient care. The Molecular Pathology Library series was created to bridge the gap between traditional basic science textbooks in molecular biology and traditional medical textbooks for organ-specific diseases. Basic Concepts of Molecular Pathology is designed as a stand-alone book to provide the pathologist, clinician or radiologist with a concise review of the essential terminology, concepts and tools of molecular biology that are applied to the understanding, diagnosis and treatment of human diseases in the age of personalized medicine. Those medical practitioners, residents, fellows and students who need to refer to the terminology and concepts of molecular pathology in their patient care will find the Basic Concepts of Molecular Pathology to be a succinct, portable, user-friendly aid in their practice and studies. The service-based physician will find this handy reference to be valuable at the laboratory benchside, at the patient bedside, at multidisciplinary patient care conferences or as a review for examinations.

Description : Marine biological science is now studied at the molecular level and although research scientists depend on information gained using molecular techniques, there is no book explaining the philosophy of this approach. Molecular Approaches to the Study of the Ocean introduces the reasons why molecular technology is such a powerful tool in the study of the oceans, describing the types of techniques that can be used, why they are useful and gives examples of their application. Molecular biological techniques allow phylogenetic relationships to be explored in a manner that no macroscopic method can; although the book deals with organisms near the base of the marine food web, the ideas can be used in studies of macroorganisms as well as those in freshwater environments.
