Epithelioses Infectieuses Et Epitheliomas

This volume is dedicated to the ethical problems related to carcinogenesis. It discusses the karyogamic theory in a new light, using new arguments, and considers the prospects of cancer prevention and treatment. The current stage of scientific development fails to answer such questions as: What is a cancer cell? What is its essence? In the opinion of most cancer researchers, the genetic apparatus of the target cell should be responsible for the conversion of a tumour cell into a normal one. This book, however, highlights the often-disregarded role of non-DNA cellular elements in carcinogenesis. It also investigates the loss of contact inhibition of cancer cells, the cellular mechanism of malignization in the case of hemolytic anemia, and the high oncogenic risk of low and medium doses of carcinogens, as well as the common trigger mechanism of action of diametrically different carcinogens on target cells.

Security sensitive microbes (viruses, bacteria, fungi, and parasites) and toxins, which are often referred to as the select agents and toxins, have the capacity to cause serious illness and death in humans, animals, and plants. Throughout history, these microbes and toxins have been exploited in one form or another as biowarfare and bioterror agents that create fear and panic well beyond any actual physical damages they might cause. Manual of Security Sensitive Microbes and Toxins provides comprehensive, state-of-the-art coverage of microbes and toxins of biosecurity concern. The ultimate goal is to increase our awareness of these agents and enhance our preparedness against any future bio-emergencies. The book begins with an introduction containing a brief overview of the historical aspects of security sensitive microbes and toxins. This is followed by a concise summary of the current status in relation to the regulation of security sensitive microbes and toxins and a discussion of future development trends. The book is divided into seven parts: Microbes and Toxins Affecting Humans and Animals: Viruses Microbes and Toxins Affecting Human and Animals: Bacteria Microbes and Toxins Affecting Human and Animals: Fungus and Parasite Microbes and Toxins Affecting Human and Animals: Toxins Microbes Affecting Animals: Viruses Microbes Affecting Animals: Bacteria Microbes Affecting Plants Written by experts in the relevant areas of research, the chapters are authoritative reviews, each one covering a single microbe or toxin with respect to its classification, biology, epidemiology, pathogenesis, identification, diagnosis, treatment, and prevention. The chapters also discuss the limitations of our current knowledge and challenges relating to improved detection and control of the microbe or toxin.

Hardbound. As its title suggests, this book is intended to give exhaustive information on virus infections and diseases occurring in ruminants. Each virus and corresponding disease is described in a separate chapter, and the chapters are ordered according to current virus classification. Contributing authors are experts on the virus and disease they describe. Where necessary, the text is accompanied by tables and pictures. The accent is placed on diagnosis of the disease by clinical observations including epizootological data. There is also a description of the laboratory procedures of diagnostic virology, and suggestions concerning control measures (e.g. vaccination and/or eradication policy).This book should prove indispensable to: the practising veterinarian, by facilitating recognition of a viral disease, and giving advice on collecting appropriate specimens for laboratory investigation; the veterinary virologist by aiding the choice of appropriate

Cancer forms a large part of urological practice. Prostate cancer is the most significant and is the second most common cause of male cancer deaths with some 300,000 cases in the USA annually. Cancer of the bladder is also common. While treatment has been primarily surgical, recent years have seen an explosion of new drug therapies for urological cancers. All urologists, whether in training or in practice, need an up-to-date survey of the literature and key findings in this important and controversial field. This book takes each organ in turn (prostate, kidney, bladder, testis and penis) and tackles the controversies head-on by inviting chapters on various (often rival) treatments for each disease. Each section is then concluded by a commentary from the editor which draws together the various strands, outlines the principal areas of consensus and disagreement. Jonathan Waxman is an oncologist who specialises in urological tumours and has developed new treatments for prostate, bladder and kidney cancer and for terminal care, which are now part of standard practice. He founded the Prostate Cancer Charity and helped establish an all-party parliamentary group to improve cancer treatment and research throughout the UK.

Positive-strand RNA viruses include the majority of the plant viruses, a number of insect viruses, and animal viruses, such as coronaviruses, togaviruses, flaviviruses, poliovirus, hepatitis C, and rhinoviruses. Works from more than 50 leading laboratories represent latest research on strategies for the control of virus diseases: molecular aspects of pathogenesis and virulence; genome replication and transcription; RNA recombination; RNA-protein interactions and host-virus interactions; protein expression and virion maturation; RNA replication; virus receptors; and virus structure and assembly. Highlights include analysis of the picornavirus IRES element, evidence for long term persistence of viral RNA in host cells, acquisition of new genes from the host and other viruses via copy-choice recombination, identification of molecular targets and use of structural and molecular biological studies for development of novel antiviral agents.
