Calcium and Calmodulin Function in the Cell Nucleus


Book Description

This book is about the role of calcium and calmodulin in the cell nucleus. Calcium, which is an important second messenger of signal transduction pathways, can also operate in the cell nucleus. Different calcium binding proteins, which are the targets of cellular calcium, have been identified in the nucleus of many different cell types. Prominent among these calcium binding proteins is calmodulin, which appears to be involved in the regulation of major nuclear functions such as gene expression and DNA replication.




The Cell: A Very Short Introduction


Book Description

Introduces cells, discussing their structure, life cycle, and what they can do.







Structure Of The Nucleus


Book Description

A graduate-level one-volume textbook and reference work on the structure and physics of atomic nuclei. Throughout this book the underlying emphasis is on how a nucleus is constituted through the interaction between the nucleons. The book is structured into three parts: the first part contains a detailed treatment of the two-nucleon force and of basic model-independent nuclear properties the second part discusses the experimental results of nuclear models and their bases in fundamental theory the third part deals in some detail with alpha-decay and fission.




Nuclear Physics


Book Description

Dramatic progress has been made in all branches of physics since the National Research Council's 1986 decadal survey of the field. The Physics in a New Era series explores these advances and looks ahead to future goals. The series includes assessments of the major subfields and reports on several smaller subfields, and preparation has begun on an overview volume on the unity of physics, its relationships to other fields, and its contributions to national needs. Nuclear Physics is the latest volume of the series. The book describes current activity in understanding nuclear structure and symmetries, the behavior of matter at extreme densities, the role of nuclear physics in astrophysics and cosmology, and the instrumentation and facilities used by the field. It makes recommendations on the resources needed for experimental and theoretical advances in the coming decade.




Compendium of Histology


Book Description

This book has been designed to help medical students succeed with their histology classes, while using less time on studying the curriculum. The book can both be used on its own or as a supplement to the classical full-curriculum textbooks normally used by the students for their histology classes. Covering the same curriculum as the classical textbooks, from basic tissue histology to the histology of specific organs, this book is formatted and organized in a much simpler and intuitive way. Almost all text is formatted in bullets or put into structured tables. This makes it quick and easy to digest, helping the student get a good overview of the curriculum. It is easy to locate specific information in the text, such as the size of cellular structures etc. Additionally, each chapter includes simplified illustrations of various histological features. The aim of the book is to be used to quickly brush up on the curriculum, e.g. before a class or an exam. Additionally, the book includes guides to distinguish between the different histological tissues and organs that can be presented to students microscopically, e.g. during a histology spot test. This guide lists the specific characteristics of the different histological specimens and also describes how to distinguish a specimen from other similar specimens. For each histological specimen, a simplified drawing and a photomicrograph of the specimen, is presented to help the student recognize the important characteristics in the microscope. Lastly, the book contains multiple “memo boxes” in which parts of the curriculum are presented as easy-to-remember mnemonics.




The Nucleus


Book Description

This volume presents detailed, recently-developed protocols ranging from isolation of nuclei to purification of chromatin regions containing single genes, with a particular focus on some less well-explored aspects of the nucleus. The methods described include new strategies for isolation of nuclei, for purification of cell type-specific nuclei from a mixture, and for rapid isolation and fractionation of nucleoli. For gene delivery into and expression in nuclei, a novel gentle approach using gold nanowires is presented. As the concentration and localization of water and ions are crucial for macromolecular interactions in the nucleus, a new approach to measure these parameters by correlative optical and cryo-electron microscopy is described. The Nucleus, Second Edition presents methods and software for high-throughput quantitative analysis of 3D fluorescence microscopy images, for quantification of the formation of amyloid fibrils in the nucleus, and for quantitative analysis of chromosome territory localization. Written in the successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, The Nucleus, Second Edition seeks to serve both professionals and novices with its well-honed methods for the study of the nucleus.




Principles of Biology


Book Description

The Principles of Biology sequence (BI 211, 212 and 213) introduces biology as a scientific discipline for students planning to major in biology and other science disciplines. Laboratories and classroom activities introduce techniques used to study biological processes and provide opportunities for students to develop their ability to conduct research.




The Nucleolus


Book Description

Within the past two decades, extraordinary new functions for the nucleolus have begun to appear, giving the field a new vitality and generating renewed excitement and interest. These new discoveries include both newly-discovered functions and aspects of its conventional role. The Nucleolus is divided into three parts: nucleolar structure and organization, the role of the nucleolus in ribosome biogenesis, and novel functions of the nucleolus.




The Nucleus, Second Edition


Book Description

The nucleus is the most prominent structure in eukaryotic cells. It houses the cell's DNA and is the hub for DNA replication, transcription, and RNA processing. Despite its prominence and importance, our understanding of how the nucleus and its DNA are organized in space and time--and the implications of that organization for proper function--has lagged behind that of other cellular structures. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology covers recent advances in our understanding of nuclear organization and function. The contributors discuss the 3D organization of chromatin, the various nuclear bodies and compartments that have been identified, and the roles of RNA and actin in shaping nuclear organization, as well as how these structures interact with each other and with peripheral features (e.g., the nuclear pore complex and inner nuclear membrane proteins) to carry out the work of the nucleus. Insights into DNA replication timing and RNA processing dynamics based on new technologies aimed at examining chromatin and other intranuclear structures at high resolution are also included. Multiple chapters are devoted to physiological and disease processes involving disruption of nuclear structure and function (e.g., viral infection). This volume is therefore essential reading for all cell and molecular biologists, as well as pathologists interested in the role of nuclear architecture in disease.
