Bacterial Chromatin


Book Description







Chromatin Structure and Dynamics


Book Description

Biological processes that replicate, preserve and use the genetic information encoded in DNA must operate in the context of chromatin, a highly organized complex of DNA and proteins. These proteins do not merely package the DNA in the tiny volume of the nucleus, but impart the structure the ability to change according to the requirements of the specific process the DNA is involved in. Moreover, chromatin structure is used by the cell to control the activity of DNA. In this volume the basics of chromatin structure and dynamics are presented by established experts in the field.




Unraveling the Exposome


Book Description

This volume presents a comprehensive overview of the science and application of the Exposome through seventeen chapters from leaders in the field. At just over ten years since the term was coined by Christopher Wild in 2005, this is the first, field-defining volume to offer a holistic picture of the important and growing field of Exposomics. The term “Exposome” describes the sum of all exposures (not only chemical) that an individual can receive over a lifetime from both exogenous sources (environmental contaminants, food, lifestyle, drugs, air, etc.) and endogenous sources (metabolism, oxidative stress, lipid peroxidation, chemicals synthesized by the microbiome, etc.). The first section of this book contains chapters that discuss how the Exposome is defined and how the concept fits into the fields of public health and epidemiology. The second section provides an overview of techniques and methods to measure the human Exposome. The third section contains methods and applications for measuring the Exposome through external exposures. Section four provides an overview on statistical and computational techniques- including big data analysis - for characterizing the Exposome. Section five presents a global collection of case studies




DNA


Book Description

In the fall of 2005, leading scientists from the National Cancer Institute announced the beginning of the cancer genome atlas project, a large-scale endeavor to map every gene implicated in cancer and the first step toward development of new therapies for treating this still baffling disease. This spin-off of the human genome project is only the latest exciting research advance in a decades-long quest to fully understand the biochemistry of the human body and thereby gain insights into the secrets of health, disease, and aging. Biochemist and veteran lab researcher Frank H. Stephenson tells the compelling story of how scientists on many fronts are succeeding in the battle against disease. With a gift for making the complexities of genetics and biochemistry understandable to the average reader, Stephenson offers a fascinating tour of the mechanisms of our body and the therapeutic techniques that are gaining in sophistication and effectiveness every year. From heart disease to AIDS and cancer, he helps you understand how the tools of biotechnology are being used to combat our most common afflictions. Stephenson examines a wide variety of health threats and illnesses: HIV infection, the many forms of cancer, asthma, diabetes, Alzheimer''s, obesity, and even erectile dysfunction. Each is discussed in terms of its root cause and treatment in plain, jargon-free language that not only educates but also entertains. This is the ideal primer on the biotechnology revolution for the layperson. Stephenson offers many insights into both the diseases that destroy health and the great promises that biotechnology offers for preserving and prolonging a healthy life.




Sperm Chromatin


Book Description

Sperm DNA damage is common and has been associated with reduced rates of conception, impaired embryonic development and increased risk of miscarriage. Although the exact causes of sperm DNA damage are unknown, it is clear that infertile men possess substantially higher levels of sperm DNA damage than do fertile men. Written by leading, internationally renowned clinicians and basic scientists with expertise in sperm DNA, Sperm Chromatin: Biological and Clinical Applications in Male Infertility and Assisted Reproduction provides readers with a thoughtful and comprehensive review of the biological and clinical significance of sperm DNA damage. The work covers the fundamental principles of sperm chromatin architecture and function, the proposed modes of DNA damage and repair, the tests of sperm DNA damage, the clinical aspects of DNA damage and the impact of DNA damage on reproductive outcome. Unlike any other title on the topic, Sperm Chromatin: Biological and Clinical Applications in Male Infertility and Assisted Reproduction is an invaluable addition to the literature and will serve as an indispensable resource for basic scientists with an interest in sperm biology and for urologists, gynecologists, reproductive endocrinologists, and embryologists working in the field of infertility.




Cell Biology A Comprehensive Treatise V2


Book Description

Cell Biology, A Comprehensive Treatise, Volume 2: The Structure and Replication of Genetic Material is mainly about the structure and replication of genetic material in both the nucleus and cytoplasmic organelles. This volume is part of the first four volumes that establish a firm foundation regarding issues of cell structure and function. These issues include cell reproduction, differentiation, and cell-to-cell interactions. This book is divided into nine chapters. Each chapter deals extensively with chromosomes – its physical, genetic, and chemical structures. In addition, this book explains the replication of chromosomes in terms of the cell cycle, as well as their coding capacity. It also discusses the functional organization (structure and levels) of the chromosomes. The concluding chapters present the DNA replication molecular principles and enzymatic machinery. Furthermore, this book explains DNA repair and its relationship to various biological endpoints. The authors of this book reasonably explain and emphasize already established facts and concepts in terms that are relatively easy to understand. Undergraduate and graduate students, teachers, researchers, scientists, and others interested or in need of information regarding cell biology will find this book of great use.
