Based on the International Symposium on Immunotherapy of Infections held recently at the Robert Koch Institute, Berlin, Germany, this work discusses cytokines as well as synthetic and natural immunomodulators and their applications in the immunotherapy of bacterial, viral, parasitic and fungal infections.;The contributors describe innovative treatment concepts that act as adjuncts to established therapies for the control of both existing and newly emerging infectious diseases.

This volume is based on the program of the Second International Conference on Drugs of Abuse, Immunity and AIDS, held in Clearwater Beach, FL in June 1992. The Conference was supported in part by the University of South Florida College of MediCine with financial assistance from the National Institute on Drug Abuse. The focus of this conference was the effects of drugs of abuse on immunity. It is now widely recognized that psychoactive drugs of abuse, including marijuana, cocaine, and opiates, as well as alcohol, have marked effects in an individual, including effects on their nervous system and behavior. In the past two decades, the scope of studies concerning the effects of some drugs of abuse have also involved investigations of alterations of various physiologic parameters including effects on the immune system. and the influence of such immune alterations on normal physiological responses. In this regard, participants in this Second International Conference provided newer information concerning both basic and clinical aspects of drugs of abuse and immunity, especially immunodeficiencies. In this regard, advances have been made in recent years concerning the nature and mechanisms whereby the immune system is regulated and the possible mechanisms by which drugs of abuse influence such immune systems. In particular, the emergence of psychoneuroimmunology as a new discipline the last decade has heightened interest in the immune responses influenced by psychoactive drugs. This has resulted in interdisciplinary investigations involving both clinical and basic scientists, including microbiologists, immunologists, physiologists, psychiatrists, oncologists, psychologists, etc.

This volume is based on the Proceedings of the International Conference on "Microbial Infections: Role of Biological Response Modifiers" held in Tampa, FL, May 29-31, 1991. The major purpose of this conference was to bring together in one forum prominent investigators from around the world studying a variety of microbial pathogens, including bacteria, viruses, and fungi, and the effects of biological response modifiers (BRM) on the immune response to these microorganisms. BRM have been widely utilized in the area of antitumor resistance and include not only experimental tumor cell vaccines, but also biologically active substances such as cytokines, i. e. , interferons, tumor necrosis factor, and interleukins, as well as products from bacteria which influence host resistance mechanisms. It is the belief of the organizers of this Conference that it was very timely to discuss in detail BRMs as they impact on microbial infections per se. It is now widely accepted that immunocompromised individuals, including those exposed to immunosuppressive substances such as antimetabolites used for chemothera py of malignancies, or infectious agents, such as the human immunodeficiency virus and other viruses which depress the immune response and, in turn, affect a host so as to become highly susceptible to opportunistic microorganisms, benefit from BRM stimulation of their immune system. A wide variety of immunomodulators are now being studied in terms of treating infectious diseases, as well as malignancy and autoimmune diseases.

The OECD review of Gender Equality in Peru: Towards a Better Sharing of Paid and Unpaid Work is the second of a series focusing on Latin American and the Caribbean countries. It compares gender gaps in labour and educational outcomes in Peru with other countries.

Cellular telephones, satellite communications and radar systems are adding to the increasing demand for radio frequency circuit design principles. At the same time, several generations of digitally-oriented graduates are missing the essential RF skills. This book contains a wealth of valuable design information difficult to find elsewhere.It's a complete 'tool kit' for successful RF circuit design. Written by experienced RF design engineers from Motorola's semiconductors product section.Book covers design examples of circuits (e.g. amplifiers; oscillators; switches; pulsed power; modular systems; wiring state-of-the-art devices; design techniques).
