Experts from The Jackson Laboratory and around the world provide practical advice on everything from how to establish a colony to where to go for specific mutations. Systematic Approach to Evaluation of Mouse Mutations includes information on medical photography, grafting procedures, how to map the genes and evaluate the special biological characteristics of the mice.

Handbook of Mouse Mutations with Skin and Hair Abnormalities presents 48 mouse mutations that are all available to the biomedical community. Many of the mouse mutations with dermatological diseases are reviewed and illustrated in detail. This popular reference book gives you a single source to use when determining which mouse mutation will best serve your needs as a biomedical tool for sophisticated research projects.

The book also includes an overview of domestic animal genodermatoses to provide alternatives to mouse models that do not exist or to complement those that do. A detailed section written by renowned experts compares the biology of human and mouse skin and skin diseases in the areas of development and the use of animal models, mammalian genetics, keratin biochemistry, epidermal and hair follicle cycles and kinetics, cytokines and growth factors, keratinocyte culture systems, cutaneous carcinogenesis, cutaneous immune system, and skin changes associated with mutations of the endocrine system.

The United States Air Force (USAF) faces a fiscally constrained environment today and will likely become even more constrained in the near future. With a reduced budget and important programs and critical functions that require funding, the USAF must find opportunities to save and reallocate these limited resources. This monograph will analyze the top-level USAF organization to address specifically whether organization and personnel changes can provide needed savings, while at the same time improving the USAF organization to support the combatant commanders and become more geographically focused to handle the complex global environment and nature of conflict. While the size of force and force structure have shrunk to the lowest points in USAF history, organizational analysis finds the USAF structure overmanned with staff officers and civilians. Further examination finds an organization with significant depth and primarily organized in a functional manner. Given these issues, this monograph proposes eliminating a layer of the USAF organization by removing major commands and promoting numbered air forces subordinate to the Headquarters USAF. This type of organization can better support combatant commands, advance USAF regional expertise and focus through the numbered air forces, adapt quicker to global situations, and also ensure important USAF history and traditions endure.

While mice have always been highly popular laboratory subjects, their suitability for genetic engineering has solidified their position as today's lab animal model of choice. However, their increased use in genetic studies has created a demand for input on phenotyping that is not always easily met. To improve the flow of information on the pathology of mice with spontaneous or genetically engineered mutations, prominent researchers organized a series of meetings. Recognizing other needs, the organizers gradually broadened their focus, until finally they expanded to provide an overview of the entire field of genetically engineered models. The Genetically Engineered Mice Handbook is an extension of those meetings. It offers an introduction for those entering into this area of research, while also serving as a resource for those presently employing mice as laboratory models. Highly comprehensive, this volume covers pertinent aspects of genetically engineered mice, including the use of models for developmental biology and the monitoring of laboratory colonies. With contributions from nearly five-dozen leading researchers, the text presents systematic approaches for analyzing mutant mice for specific medical applications, details a variety of methods for creating mutants and includes information that is particularly hard to access dealing with legal responsibilities. This essential reference examines commonly used traditional, as well as emerging, technologies To address the purpose of the original meeting, the Genetically Engineered Mice Handbook directs researchers to the best public websites, and offers instruction on how to use them. In the past, as their work dictated, researchers would seek out experts on particular organ systems. Now groups of experts work together to generate these websites, providing the latest data as well as discussions over points of debate. These sites do not eliminate the need for a trained pathologist, but they do provide reference materials for those lacking expertise in particular anatomic structures. They also offer much greater numbers of examples than are available in print, from which biomedical researchers can draw.
