Book excerpt: We have previously postulated that wild-type Herpes Simplex Virus type I (HSV-1) infections are characterized by the presence of a fusion factor and a fusion inhibitor activity. The fusion inhibitor presumably is dominant so that a small fraction of cells fuse in a typical wild-type infection. Furthermore, the syn mutants isolated in our laboratory are thought to cause extensive cell fusion because the production of active fusion inhibitor in cell membranes is delayed. If mutations existed that altered both the fusion factor and fusion inhibitor activity then separate viruses containing these two mutations might be able to complement each other, each supplying the defective gene product missing in the other virus. This would produce a wild type and not a syncytial mutant response. Complementation tests between two viruses, tsB5 and syn 20, which are thought to contain defects in the production of active fusion factor and fusion inhibitor activity, respectively, were done. A wild-type response was observed indicating that the mutations affecting fusion were in two separate genes.

Available in PDF, EPUB and Kindle. Book excerpt: We have determined the extent of fusion in mixed Herpes Simplex Virus type 1 (HSV-1) cell populations. Labeled, sparse, infected cells were surrounded by unlabeled, excess, uninfected (or infected) cells to determine if fusion inhibition is active when present in the same cell as fusion factor, when present in cells that do not contain fusion factor, or in both situations. We found that wild type infected cells fuse to the same extent with each other as with uninfected cells. Therefore fusion inhibitor is active when present in the same cell as fusion factor. Other experiments indicate that the inhibition activity can also cause a small decrease of fusion when fusion factor and fusion inhibitor are present in different, but neighboring, cells. Marked variations are found in the capacity of different cell types, such as human embryonic lung (HEDL) and HEp-2 to support fusion by particular syn mutants. The difference in fusion capacity of the two cell types may be due to a difference in a cellular factor affecting the activity of viral, fusion-associated molecules, and not to cell surface differences of the uninfected cells.

This book was released on 2011-01-27 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: A respected resource for decades, the Guide for the Care and Use of Laboratory Animals has been updated by a committee of experts, taking into consideration input from the scientific and laboratory animal communities and the public at large. The Guide incorporates new scientific information on common laboratory animals, including aquatic species, and includes extensive references. It is organized around major components of animal use: Key concepts of animal care and use. The Guide sets the framework for the humane care and use of laboratory animals. Animal care and use program. The Guide discusses the concept of a broad Program of Animal Care and Use, including roles and responsibilities of the Institutional Official, Attending Veterinarian and the Institutional Animal Care and Use Committee. Animal environment, husbandry, and management. A chapter on this topic is now divided into sections on terrestrial and aquatic animals and provides recommendations for housing and environment, husbandry, behavioral and population management, and more. Veterinary care. The Guide discusses veterinary care and the responsibilities of the Attending Veterinarian. It includes recommendations on animal procurement and transportation, preventive medicine (including animal biosecurity), and clinical care and management. The Guide addresses distress and pain recognition and relief, and issues surrounding euthanasia. Physical plant. The Guide identifies design issues, providing construction guidelines for functional areas; considerations such as drainage, vibration and noise control, and environmental monitoring; and specialized facilities for animal housing and research needs. The Guide for the Care and Use of Laboratory Animals provides a framework for the judgments required in the management of animal facilities. This updated and expanded resource of proven value will be important to scientists and researchers, veterinarians, animal care personnel, facilities managers, institutional administrators, policy makers involved in research issues, and animal welfare advocates.
