Originally published in 1993, this volume describes supplementary tests used to assess risks of in vitro mutagenicity when basic safety tests were inconclusive.
Radiation Research: Biomedical, Chemical and Physical Perspectives documents the proceedings of the Fifth International Congress of Radiation Research held in Seattle, Washington, 14-20 July 1974. While the focus of the Congress was on fundamental research, there were several well-attended sessions on the practical aspects of radiation research as it relates to radiotherapy, central station power generation by both nuclear fission and fusion, and the environment. This volume contains 126 papers organized into 31 parts. Beginning with a keynote address and a lecture on the time scale in radiobiology, the subsequent contributions cover a wide range of topics presented over several sessions. Topics discussed during these sessions include energy needs, nuclear power, and the environment; prospects for fusion power; technological applications of radiation; human radiobiology; hazards of radiation exposure relative to other environmental agents; the basic physics of the interactions of radiation with matter; particle penetration phenomena; and radiation effects in frozen media.
During the last decades, cancer diseases have increased all over the world. The low quality of food and strong pollution of environment are the main prerequisites for carcinogenesis. The main problem for scientists is to find strategy for prevention of cancer diseases. Therefore, the information about the models for studying carcinogenesis and mutagens which appear during cooking, environmental pollutants, and tests for specific detection of carcinogens is particularly important. The book "Carcinogen" is intended for biologists, researchers, students in medical sciences and professionals interested in associated areas.
A high profile thought experiment asks leading scholars to make cases for spending additional aid money to combat major world problems.
This assay may be used to measure mitotic recombination (gene conversion or crossingover) in yeast, a eukaryotic micro-organism. Crossing-over is generally assayed by the production of recessive homozygous colonies or sectors produced in a ...

Bacteria are estimated to cause some 24 million cases of diarrheal disease annually in the US. These papers have wide importance providing background information and recent research findings and giving a comprehensive, current understanding of bacterial pathogens associated with foods and their role
Bile acids are increasingly being seen as extremely important carcinogenic agents in cancers of the bile duct, liver, colon, rectum, and oesophagus. They are essential agents involved in lipid digestion and absorption in mammals, however, they also play wide-ranging roles in a variety of disease states ranging from diabetes to cancer. They have evolved exquisite mechanisms for controlling their own synthesis and to ensure that they are produced at correct concentrations and also kept in the correct anatomical environment. It is only when these fine levels of controls are breached that Bile aci.
This volume on drug metabolism covers the contribution that transgenic animal research, UDP-glucuronosyltransferases, CNS penetration advances and anticancer drugs can make to the subject.
