Two strands, one indigenous, the other imposed, pro-duce the poetic and cultural tensions that give form to the work of five contemporary Mexican poets—All Chumacero, Efrain Huerta, Jaime Sabines, Ruben Bonifaz Nuno, and Rosario Castellanos. Although all five are significant figures, only Castellanos has yet been widely studied in the United States, primarily for her novels and her relations with the feminist movement. In spite of a number of rather basic differences in their work, these poets share and write within a complicated culture rooted in both the pre-Hispanic and the European traditions. Their poetry reflects this in its emphasis on death as a constant presence and in the echoes of both Aztec ritual poetry and European poetry. Although apparently very different formally and thematically, the five share a number of concerns. Each of them writes out of a contradictory inner tension; each is preoccupied with the effort to shape language as part of a personal voyage of discovery; each is haunted by death and seeks realization or plenitude through love of some kind. And each of them, ultimately, finds there is no escape. As Frank Dauster concludes, "The poetry of Mexico, like its people and its society, reflects the fusion of two worlds, and these complex poets of the double strand operate freely and imaginatively within it." Although addressed primarily to specialists in Latin American literature, The Double Strand also speaks to those interested in the complex interaction between two widely differing cultural heritages, and in the rich fusion this blending produces in Mexican letters.

The field of DNA repair is vast and advancing rapidly. Recent investigations have begun to focus on the involvement of chromatin in the repair of broken DNA. Although I have no doubt that many breakthroughs in our understanding of chromatin, chromatin regulation, and DNA repair lie in our future, presently this is a new line in inquiry. As such there are many, many unanswered questions. Indeed, most of the correct questions have probably not even been asked yet. Here I have attempted to present a review of some of the current body of knowledge that may prove relevant to understanding the role of chromatin in DNA repair. Because the volume of research, and the relevant findings, come from a staggering array of labs, systems, and ideas I have focused primarily on findings developed from the study of the budding yeast Saccharomyces cerevisiae. Unfortunately, this means that I have left out a great deal of information. It is my hope, however, that the information I do detail, particularly in Chapter 1, will give a flavor for the scope of the problem and perhaps highlight some of the interesting directions this field is taking, or may one day take. I would also point out that the primary research that is presented herein is not in any way meant to represent the comprehensive scope of research being performed. To understand DNA repair will require investigation from innumerable labs, performed by innumerable researchers, moving in unexpected directions.

Written by experts from Washington University School of Medicine, this text is a thorough review of the specific molecular genetic techniques that can provide diagnostically useful molecular genetic information on tissue samples—including cytogenetics, fluorescence in situ hybridization (FISH), PCR, electrophoresis and hybridization analysis, DNA sequence analysis, and microarrays. The first part of the book describes each technique, indicates its advantages, disadvantages, capabilities, and limitations, and systematically addresses sensitivity and specificity issues. Subsequent chapters, organized by organ system, detail the specific applications of these tests in surgical pathology. More than 150 full-color and black-and-white illustrations complement the text.

Molecular Biology or Molecular Genetics - Biology Department Biochemical Genetics - Biology or Biochemistry Department Microbial Genetics - Genetics Department The book is typically used in a one-semester course that may be taught in the fall or the spring. However, the book contains sufficient information so that it could be used for a full year course. It is appropriate for juniors and seniors or first year graduate students.

This book provides a qualitative and quantitative exploration of the action of radiation on living matter which leads to a complete and coherent interpretation of radiation biology. It takes readers from radiation-induced molecular damage in the nucleus of the cell and links this damage to cellular effects such as cell killing, chromosome aberrations and mutations before exploring organ damage, organism lethality and cancer induction. It also deals with radiological protection concepts and the difficulties of predicting the dose–effect relationship for low-dose and dose rate radiation risk. The book ends with separate chapters dealing with the effects of UV light exposure and risk classification of chemical mutagens, both of which are derived by logical extensions of the radiation model. This book will provide the basic foundations of radiation biology for undergraduate and graduate students in medical physics, biomedical engineering, radiological protection, medicine, radiology and radiography. Features Presents a comprehensive insight into radiation action on living matter Contains important implications for radiological protection and regulations Provides analytical methods for applications in radiotherapy

The explosion of the field of genetics over the last decade, with the new technologies that have stimulated research, suggests that a new sort of reference work is needed to keep pace with such a fast-moving and interdisciplinary field. Brenner's Encyclopedia of Genetics, Second Edition, Seven Volume Set, builds on the foundation of the first edition by addressing many of the key subfields of genetics that were just in their infancy when the first edition was published. The currency and accessibility of this foundational content will be unrivalled, making this work useful for scientists and non-scientists alike. Featuring relatively short entries on genetics topics written by experts in that topic, Brenner's Encyclopedia of Genetics, Second Edition, Seven Volume Set provides an effective way to quickly learn about any aspect of genetics, from Abortive Transduction to Zygotes. Adding to its utility, the work provides short entries that briefly define key terms, and a guide to additional reading and relevant websites for further study. Many of the entries include figures to explain difficult concepts. Key terms in related areas such as biochemistry, cell, and molecular biology are also included, and there are entries that describe historical figures in genetics, providing insights into their careers and discoveries. This 7-volume set represents a 25% expansion from the first edition, with over 1600 articles encompassing this burgeoning field Thoroughly up-to-date, with many new topics and subfields covered that were in their infancy or not inexistence at the time of the first edition. Timely coverage of emergent areas such as epigenetics, personalized genomic medicine, pharmacogenetics, and genetic enhancement technologies Interdisciplinary and global in its outlook, as befits the field of genetics Brief articles, written by experts in the field, which not only discuss, define, and explain key elements of the field, but also provide definition of key terms, suggestions for further reading, and biographical sketches of the key people in the history of genetics
