The Causes and Consequences of Chromosomal Aberrations explores one of the most dramatic examples of genomic instability-chromosomal aberrations. It describes some of the more recent techniques used to map genes within the human genome, study chromosomal aberrations at the cellular level, and define the organization of the interphase nucleus. General overviews are provided to build a conceptual framework for understanding the generality and specificity of chromosomal aberrations. The Causes and Consequences of Chromosomal Aberrations also explores the role of recombinases and topoisomerases in the development of chromosomal aberrations. It contains studies of chromosomal aberrations, which offer separate instructive treatises on specific malignancies. The Causes and Consequences of Chromosomal Aberrations is useful to medical and graduate students, physicians, molecular biologists, and cytogeneticists. It will benefit anyone interested in the concepts, contributions, and development in the field of molecular cytogenetics.

Chromosomale Mutationen sind eine der m|glichen Ursachen f}r Ver{nderungen der Erbinformation. Neben grunds{tzlichen As- pekten, wie Reparaturmechanismen der Zelle oder Ursachen von Chromosomenver{nderungen, werden angewandte Aspekte, z.B. Chromosomen als Testindikatoren der Toxizit{t, behandelt.

Modern Trends in Physiological Sciences, Volume 32: Human Afflictions and Chromosomal Aberrations presents the study of the links between chromosome aberrations and physical and mental congenital anomalies. This book discusses the possibilities of human cytogenetic research as well as its difficulties. Organized into 15 chapters, this volume begins with an overview of the development of human chromosome investigations. This text then explains the methods for studying human chromosomes, which can be applied without controlling the atmosphere of the incubator. Other chapters describe the structural features of the normal human karyotype. This book discusses as well the early appearance of a chromosome aberration that produces a change in the hereditary patrimony manifest in a constitutional disorder of the individual. The final chapter deals with the biochemical effects that correspond to numerical or structural anomalies in chromosome 21. This book is a valuable resource for genetecists, cytogeneticists, physicians, and clinical researchers.

Chromosomal aberrations are disruptions in the normal chromosomal content of a cell, and are a major cause of genetic conditions in humans, such as Down syndrome. Some chromosome abnormalities do not cause disease in carriers, such as translocations, or chromosomal inversions, although they may lead to a higher chance of having a child with a chromosome disorder. Abnormal numbers of chromosomes or chromosome sets, aneuploidy, may be lethal or give rise to genetic disorders. Genetic counseling is offered for families that may carry a chromosome rearrangement. This book offers leading-edge research from around the world.

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.

Due to sensitive molecular biological techniques, our understanding of chromosomal aberrations is steadily increasing. Provided here is a review of basic and applied aspects of the field. Chromosome structure, induction of DNA lesions by different clastogenic agents and their repair, induction of aberrations by agents which affect specific sequences in the DNA, and factors affecting induction and yield of chromosomal aberrations are covered. Further, topics such as automation of aberration scoring, problems associated with using chromosomal aberrations and micronuclei in population monitoring and the importance of chromosomal aberration assays in mutagenicity testing of chemicals are included.
