There is now a range of cytotoxic drugs that have considerable clinical usefulness in producing responses in tumors and even, in a small proportion of cases, cure. However, the acquisition of drug resistance is a major clinical problem and is perhaps the main limiting factor in successful treatment of cancer. Thus, a tumor initially sensitive to chemotherapy will, in the majority of cases, eventually recur as a resistant tumor, which will then progress. Much of our understanding of drug resistance mechanisms comes from the study of tumor cell lines grown in tissue culture. We now understand many of the - lecular mechanisms that can lead to a cell acquiring resistance to antic- cer drugs; how...
Now fully updated and considerably expanded, Glycoanalysis Protocols, 2nd ed., makes available to all protein scientists, and particularly those working with today's pharmaceuticals, the most advanced and reproducible glycoanalysis techniques currently in use. Developed by highly experienced carbohydrate chemists, biochemists, and physical chemists, these detailed, up-to-date, and proven analytical techniques cover the areas of glycoprotein macromolecular structural analysis, oligosaccharide profiling, lipid conjugate characterization, microorganism structure determination, and proteoglycan function. Special attention has been given to advanced analytical techniques in biotechnology during the production of recombinant glycoproteins and other therapeutics. Hailed as "indispensable" in its first edition, Glycoanalysis Protocols, 2nd ed., continues with vital, time-tested techniques addressing the needs of both biomedical researchers and protein macromolecular structural chemists. It will well serve all those starting work on the analysis of glycoproteins, as well as more experienced investigators seeking to augment their expertise.
A collection of cutting-edge techniques for detecting most of the major viruses that afflict mankind, including influenza, hepatitis, herpes, polio, mumps, HIV, and many more. The techniques are well-tested, easily reproducible, and readily employ all the new technologies-PCR, RIA, ELISA, and latex-agglutination-that have revolutionized the field. These methods not only make it possible to do the necessary analysis in hours instead of days, but can also be automated in a laboratory havng only low levels of biological containment. Frequently, the protocols for viruses causing human diseases can be adapted to similar viruses of veterinary importance. Through its state-of-the-art methods a physician can, for the first time, determine early in a viral infection which antiviral drug should be used and minimize the period of treatment to avoid unnecessary side effects.
Soon after the first description of monoclonal antibodies in 1976, there was enormous interest in the clinical application of antibodies, especially in the context of cancer. Antibodies appeared to offer the “magic bullet” that would allow the specific destruction of neoplastic cells. H- ever, many years’ effort resulted in very few cases of successful immu- therapy with antibodies. As a result there was a major backlash against antibody therapy, and the field lost a considerable amount of popularity. Fashion, in science as well as in other things, tends to be cyclical. Antibody-based therapy is once again attracting scientists and clinicians. There are several reasons for the renewed ...
The worldwide impact of infection with human immunodeficiency virus type 1 (HIV- is reflected in the cumulative number ofHIV- 1 infections, which is now predicted to exceed 40 million by the year 2000---equivalent to the n- ber of humans who perished in World War II. The medical and scientific - sponse to the HIV-1 pandemic has steadily grown since its recognition in 1981. The outlay by the United States alone for HIV research funded by the National Institutes of Health in 1997 was $1. 4 billion. Laboratory-based HIV research has brought together academic clinicians, retrovirologists, molecular biologists, and immunologists in the formation of research teams attempting to dissect the viral a...
This book is a complete guide to gastrointestinal diseases and disorders for trainees in gastroenterology. Sixteen sections each cover a different symptom, explaining signs, clinical features, investigation methods, differential diagnosis and treatment. Topics include chronic abdominal pain, anorectal problems, gastrointestinal bleeding, eating disorders, jaundice, abdominal masses, liver failure, and much more. Authored by Consultant Gastroenterologist Her Hsin Tsai from Hull and East Yorkshire Hospitals NHS Trust, this practical text is further enhanced by more than 350 clinical photographs, radiological images, diagrams and tables to assist learning. Key points Complete guide to gastrointestinal diseases and disorders for trainees Covers many different symptoms, their clinical features, investigation, differential diagnosis and treatment Authored by recognised Hull-based Consultant Gastroenterologist Highly illustrated with clinical photographs, radiological images, diagrams and tables
This latest addition to the Methods in Molecular Medicine series, Anti- ral Methods and Protocols, is opportune because there is an increasing int- est in discovering compounds that are effective against both chronic and acute viral infections. A number of the methods described in the volume are unp- lished and their inclusion indicates the speed at which this field is moving. This volume is not a review but each chapter contains methods validated by the experts who have spent time in developing the protocols. The hallmark of this series is the comprehensive way in which the me- ods are described, which includes a list of all the reagents needed for each protocol. Of importance is the section on tips and pitfalls that the authors have discovered while developing their protocols. The manual itself is designed to be used by researchers in universities and industry who are familiar with a range of biological techniques but who want to set up quickly a novel assay system. We encourage a dialog between readers and authors, which may also result in useful collaborations.
Laboratory studies in hemostasis have traditionally focused on abn- malities of platelet function or the quantitative and qualitative disorders that affect the proteins involved in blood coagulation. However, over the last 10 years there has been an explosion in our understanding of the molecular bases that underlie many of the inherited and acquired disorders of hemostasis. Many of these disorders are now routinely diagnosed and assessed by methods that involve genotypic analysis. Indeed in the late 1990s the distinction between molecular methods for research and for routine diagnosis is becoming incre- ingly blurred. The techniques and approaches that are used in hemostasis are manifold an...
In recent years, molecular techniques have enhanced our ability to detect sexually transmitted infections and to conduct research to further our und- standing of sexually transmitted diseases. Molecular methods to quantitate pathogen load have also been shown to be useful for the management of HIV and other viral STDs. Existing laboratory manuals for the clinical microbi- ogy laboratory often do not include molecular methods for STDs. Sexually Transmitted Diseases: Methods and Protocols is intended to fill the need for a dedicated manual that covers all the fundamental aspects of molecular pro- cols for laboratory diagnosis, as well as research methodology for STDs, - cluding HIV. There are more than types of molecular techniques described in this book covering nine major sexually transmitted pathogens. Although mole- lar methods for the detection of such pathogens as Trichomonas vaginalis are available in the published literature, they have not been included since they are not yet widely used for laboratory diagnosis or research. Sexually Transmitted Diseases: Methods and Protocols is one of a series of books treating Methods Molecular Medicine, published by Humana Press.
