Red Conspirator
Author: Thomas L. Sakmyster

Publisher: University of Illinois Press
Release Date: 2011
The author traces Peters's activities from his arrival in the United States to the dawn of the Cold War and his deportation back to Hungary. Known as the "Hungarian man of mystery," Peters emigrated to the United States in 1924 after serving in the Austrian Army during World War I. In America, he oversaw a false passport operation that facilitated the movement of Soviet agents to the United States and American communists to the Soviet Union. Working under a number of aliases, he constructed a complex network of informants and spies that stole numerous State Department documents in the 1930s. After years of hiding underground he was arrested and deported in 1949. The author reveals Peters to be not just the influential leader of conspiratorial Communist activities but also an organizer in the open American Communist party. The author of a handbook on Communism, Peters also set up a program to infiltrate the armed forces in the United States.
Essentials of Stem Cell Biology
This abridged version of the bestselling reference Handbook of Stem Cells, Two-Volume Set attempts to incorporate all the essential subject matter of the original two-volume edition in a single volume. The material has been reworked in an accessible format suitable for students and general readers interested in following the latest advances in stem cells, including full color presentation throughout. Although some extra language and chapters have been deleted, rigorous effort has been made to retain from the original two-volume set the material pertinent to the understanding of this exciting area of biology.The organization of the book remains largely unchanged, combining the prerequisites for a general understanding of adult and embryonic stem cells; the tools, methods, and experimental protocols needed to study and characterize stem cells and progenitor populations; as well as a presentation by the world's experts of what is currently known about each specific organ system.* Full-color presentation througout* Each chapter begins with 3-5 defined glossary terms, and all of the terms are collected in a comprehensive list within the book* References have been eliminated - now there are about 10 bibliographic entries per chapter
Stress and Environmental Regulation of Gene Expression and Adaptation in Bacteria

Bacteria in various habitats are subject to continuously changing environmental conditions, such as nutrient deprivation, heat and cold stress, UV radiation, oxidative stress, dessication, acid stress, nitrosative stress, cell envelope stress, heavy metal exposure, osmotic stress, and others. In order to survive, they have to respond to these conditions by adapting their physiology through sometimes drastic changes in gene expression. In addition they may adapt by changing their morphology, forming biofilms, fruiting bodies or spores, filaments, Viable But Not Culturable (VBNC) cells or moving away from stress compounds via chemotaxis. Changes in gene expression constitute the main component of the bacterial response to stress and environmental changes, and involve a myriad of different mechanisms, including (alternative) sigma factors, bi- or tri-component regulatory systems, small non-coding RNA’s, chaperones, CHRIS-Cas systems, DNA repair, toxin-antitoxin systems, the stringent response, efflux pumps, alarmones, and modulation of the cell envelope or membranes, to name a few. Many regulatory elements are conserved in different bacteria; however there are endless variations on the theme and novel elements of gene regulation in bacteria inhabiting particular environments are constantly being discovered. Especially in (pathogenic) bacteria colonizing the human body a plethora of bacterial responses to innate stresses such as pH, reactive nitrogen and oxygen species and antibiotic stress are being described. An attempt is made to not only cover model systems but give a broad overview of the stress-responsive regulatory systems in a variety of bacteria, including medically important bacteria, where elucidation of certain aspects of these systems could lead to treatment strategies of the pathogens. Many of the regulatory systems being uncovered are specific, but there is also considerable “cross-talk” between different circuits. Stress and Environmental Regulation of Gene Expression and Adaptation in Bacteria is a comprehensive two-volume work bringing together both review and original research articles on key topics in stress and environmental control of gene expression in bacteria. Volume One contains key overview chapters, as well as content on one/two/three component regulatory systems and stress responses, sigma factors and stress responses, small non-coding RNAs and stress responses, toxin-antitoxin systems and stress responses, stringent response to stress, responses to UV irradiation, SOS and double stranded systems repair systems and stress, adaptation to both oxidative and osmotic stress, and desiccation tolerance and drought stress. Volume Two covers heat shock responses, chaperonins and stress, cold shock responses, adaptation to acid stress, nitrosative stress, and envelope stress, as well as iron homeostasis, metal resistance, quorum sensing, chemotaxis and biofilm formation, and viable but not culturable (VBNC) cells. Covering the full breadth of current stress and environmental control of gene expression studies and expanding it towards future advances in the field, these two volumes are a one-stop reference for (non) medical molecular geneticists interested in gene regulation under stress.
