The subunits all share a common topology, possessing two transmembrane domains one about residues from their N-termini, the other near residuesa large extracellular loop and intracellular carboxyl and amino termini Figure 1 [3] The extracellular receptor domains between these two segments of about residues are well conserved with several conserved glycyl residues and 10 conserved cysteyl residues. The amino termini contain a consensus site for protein kinase C phosphorylation, indicating that the phosphorylation state of P2X subunits may be involved in receptor functioning.

Key Concepts This edition of the Guide for the Care and Use of Laboratory Animals the Guide strongly affirms the principle that all who care for, use or produce animals for research, testing or teaching must assume responsibility for their well-being. The Guide plays an important role in decision- making regarding the use of vertebrate laboratory animals, because it establishes the minimum ethical, practice and care standards for researchers and their institutions.

The use of laboratory animals in research, teaching, testing and production is also governed or impacted by various federal and local laws, regulations and standards.

Compliance with these laws, regulations, policies, and standards or subsequent revised versions in the establishment and implementation of a program of animal care and use is discussed in Chapter 2.

Taken together, the practical effect of these laws, regulations, and policies is to establish a combined system of self-regulation and regulatory oversight that binds researchers and institutions using animals. Both researchers and institutions have affirmative duties of humane care and use that are supported by practical, ethical and scientific principles.

This system of self-regulation establishes a rigorous program of animal care and use and provides flexibility in fulfilling the responsibility to provide humane care. The specific scope and nature of these responsibilities can vary based on the scientific discipline, nature of the animal use, and species involved.

Nevertheless, these responsibilities, which affect animal care and use in every situation, require that producers, teachers, researchers and institutions carry out purposeful analyses of proposed uses of laboratory animals.

The Guide is central to carrying out these analyses and constructing a program in which humane care is incorporated into all aspects of laboratory animal care and use. The Guide is created by scientists and veterinarians for scientists and veterinarians to uphold the scientific rigor and integrity of biomedical research with laboratory animals as expected by their colleagues and society at large.

In the Guide laboratory animals also referred to as animals are generally defined as any vertebrate animal e. Animal use is defined as the proper care, use and humane treatment of laboratory animals produced for, or used in research testing or teaching.

Animal use - The proper care, use and humane treatment of laboratory animals produced for, or used in research testing or teaching. When appropriate, considerations or specific emphases for agricultural animals and non-traditional species are presented. The Guide does not address in detail agricultural animals used in production agricultural research or teaching, wildlife and aquatic species studied in natural settings, or invertebrate animals e.

Nevertheless, the Guide establishes general principles and ethical considerations that are also applicable to these species and situations. References in the Guide provide the reader with additional information regarding statements made in the Guide.

Supplemental information on breeding, care, management, and use of selected laboratory animal species is available in other publications prepared by the Institute for Laboratory Animal Research ILAR and other organizations Appendix A.

The goal of the Guide is to promote humane care and use for laboratory animals.

The Committee recognizes that the use of different species in research is expanding, and that researchers and institutions will face new and unique challenges in determining how to apply the Guide in these situations.

In making these determinations, it is important to keep in mind that the Guide is intended to provide information to assist researchers, institutional animal care and use committees IACUCsveterinarians, and the other stakeholders in assuring the implementation of effective and appropriate animal care and use programs that are based on humane care.

The objective is to provide information that will enhance animal well-being, the quality of research, and the advancement of scientific knowledge that is relevant to both humans and animals.The development of molecu- systems, fluid and rapid reconfiguration of both the periphery and nervous lar tools to survey changes in the transcript profile of thousands of genes has system are utilized to generate qualitatively different behaviors.

Oct 20,  · Dissection Frogs Central Nervous System Dissection of an adult bullfrog's central nervous system (CNS) Experiment consists of the dissection and analyzation of a bullfrogs nervous system.

Dissection consists of the isolation of the CNS consisting of the brain and spinal cord. It also consists of analyzing the nervous tissue under the microscope.
