Phytochemicals are components acting individually, additively or
synergistically, usually as a component of whole food, that have
the characteristics of providing protective, preventative and
possibly curative roles in the pathogenesis of cancer and other
chronic disease progressions. Nutraceutical is a term used to
describe beneficial phytochemicals. The mechanisms of action of
nutraceuticals may be one of several. Free radical scavenger and
antioxidant nutraceuticals can nullify damage by any number of
biochemical mechanisms, but some also exert benefit by enhancing
immune function. A conservative economic analysis was done in 1993 of solely
hospital care costs and the roles that three nutrient antioxidants
could exert on cardiovascular disease, breast cancer and cataracts.
The study considered the potential impact of only three
antioxidants, vitamins C and E, and beta-carotene, and the possible
annual savings in hospital care costs alone, which could exceed 8
billion dollars. Expert public health physicians believe that as
much as 700f disease is preventable. The chapters in this book were organized to reveal existing and
emerging knowledge of nutraceuticals found in garlic, soy and
licorice. Lead chapters discuss the epidemiological evidence, and
following chapters discuss chemical or biochemical evidence at the
cellular level, as well as the presentation of some clinical
data. A major conclusion of the overall effort is that the science of nutraceuticals is very incomplete, but that findings to date have great promise.
This book discusses the recent developments in the therapeutic implications of cancer stem cells for the effective diagnosis, prognosis, and treatment of cancer. It summarizes the various stem cells of common cancers including colon, pancreas, lungs, prostate, melanoma, and glioblastoma, and reviews the potential role of cancer stem cells in tissue aggressiveness, examining the functional contribution of cancer stem cells in the establishment and recurrence of cancerous tumors. Further, it explores the potential of cancer stem cells as novel therapeutic targets for the treatment and prevention of tumor progression. The book also discusses the various approaches for detecting, isolating, and characterizing different cancer stem cells and signaling pathways that control their replication, survival, and differentiation. Lastly, it explores the key features and mechanisms of drug resistance, chemo-resistance, and radio-resistance in cancer stem cells to improve therapeutic rationale.

This monograph contains a description of the discovery and development of a antisecretory therapy in the treatment of acid-related diseases: omeprazole, the first proton pump inhibitor. Overviews compare this and other proton pump inhibitors and discuss their pharmacology, including the mechanism of action, the effect on Helicobacter pylori infection, and the consequences of profound inhibition of gastric acid secretion. The pharmaceutic delivery system is described since it constitutes a special problem with this class of drugs. The clinical experience with proton pump inhibitors in acid-related diseases is reviewed with focus on gastro-esophageal reflux disease and peptic ulcer diseases including Helicobacter pylori and NSAID-induced ulcerations and Zollinger-Ellison syndrome. Finally, an overview is presented on the socio-economic impact of proton pump inhibitors in acid-related diseases emphasizing the important aspect of quality of life. The monograph is aimed at a broad readership with an interest in the development problems of this, at present, most commercially successful drug; the pharmacology of a "tailor-made" drug for a specific target; the therapeutic strategies in acid-related diseases; and the dramatic changes in the long-term outcome results of the treatment of peptic ulcer diseases where most patients now can be cured from the disease after only one week of drug therapy.
Recent years have seen unprecedented outbreaks of avian influenza A viruses. In particular, highly pathogenic H5N1 viruses have not only resulted in widespread outbreaks in domestic poultry, but have been transmitted to humans, resulting in numerous fatalities. The rapid expansion in their geographic distribution and the possibility that these viruses could acquire the ability to spread from person to person raises the risk that such a virus could cause a global pandemic with high morbidity and mortality. An effective influenza vaccine represents the best approach to prevent and control such an emerging pandemic. However, current influenza vaccines are directed at existing seasonal influenza viruses, which have little or no antigenic relationship to the highly pathogenic H5N1 strains. Concerns about pandemic preparedness have greatly stimulated research activities to develop eff- tive vaccines for pandemic influenza viruses, and to overcome the limitations inh- ent in current approaches to vaccine production and distribution. These limitations include the use of embryonated chicken eggs as the substrate for vaccine prod- tion, which is time-consuming and could involve potential biohazards in growth of new virus strains. Other limitations include the requirement that the current inac- vated influenza vaccines be administered using needles and syringes, requiring trained personnel, which could be a bottleneck when attempting to vaccinate large populations in mass campaigns. In addition, the current inactivated vaccines that are delivered by injection elicit limited protective immunity in the upper respiratory tract where the infection process is initiated.
The majority of cancers present at a relatively advanced stage in which invasion within the primary organ is well established and metastases to lymph and distant organs are either clinically apparent or present at the microscopic level. However, it is increasingly recognized that the natural history of cancer formation is a long and complex path taking many years to develop to a clinically apparent stage in most cases. Furthermore, for most solid tumours there is a pre-invasive or intraepithelial stage of disease. This affords the opportunity for early detection and prevention of invasive disease and hence a cure. However, with this advancing knowledge comes a whole plethora of questions which will be explored in this monograph. Firstly, we need to understand the global burden of pre-invasive disease and what the public health implications might be for wide-scale screening programmes. In the western world we already have experience of screening for cervical, breast, prostate and more recently colon cancer. As well as their potential benefits these programmes have financial and psychosocial implications which need to be carefully weighed. This is especially true since many pre-invasive lesions will not progress to cancer in a individual's lifetime. In addition, there are questions concerning whether screening reduces the cancer burden or in fact distorts the survival figures through lead-time bias. Secondly, at the level of epidemiology and molecular pathogenesis there are important questions regarding the aetiology of pre-invasive lesions; an understanding of which might lead to possible chemopreventive strategies. For example, it would be helpful to know the extent to which the likelihood of developing a pre-invasive lesion is influenced by lifestyle or genetic factors and how these factors influence the risk of progression to invasive disease. At the molecular level we need to understand the pathways and molecular mechanisms, both genetic and epigenetic, by which cells achieve the capacity to invade. Thirdly, in order make clinical progress we need biomarkers to identify and risk stratify individuals with pre-invasive lesions. These biomarkers might be applied to the serum as in Prostate Specific Antigen in prostate cancer or be applied to tissue samples, such as oestrogen receptor status in breast cancer. In order to utilize biomarkers in the context of a screening programme there are issue around the invasiveness of the test as well as its positive and negative predictive value. With advances in molecular imaging there is now the exciting possibility of incorporating a molecular tag to a non-invasive imaging modality. Fourthly, in order to justify screening early detection must be coupled to a treatment strategy. If the chemopreventive agent is very well tolerated, then as well as targeting high risk groups, one might consider treatment at the population level. Aspirin is one such drug which has been extensively assessed in the context of colon cancer chemoprevention trials. Trials of aspirin chemoprevention are now being applied to other cancers such as oesophageal adenocarcinoma and since many individuals take aspirin for .chemoprevention of cardiovascular disease the cancer incidence can be ascertained in these populations. In order to understand the more general issues raised from the discussions above it is useful to consider disease specific examples. Our understanding of pre-invasive disease varies according to the organ site and there are lessons to be learned from these experiences. For example, there is now the prospect of a vaccine for cervical cancer with important questions about how this might be applied to the high incidence areas of the developing world. On the other hand, ductal carcinoma in situ is currently treated by mastectomy which is more radical than the treatment received by many women with invasive disease. Oesophageal adenocarcinoma, which is my own area of expertise is interesting because of the rapid rise in incidence in the western world and the clinically accessible pre-invasive lesion called Barrett's oesophagus. However, most cases of Barrett's oesophagus remain undiagnosed and it is not yet clear how to effectively diagnose, monitor and treat this condition without recourse to mass endoscopy with substantial cost implications. In conclusion, in an era in which preventive medicine is a major concern for consumers, health-policy makers and politicians pre-invasive disease is likely to become a major part of cancer medicine.
The reader will be introduced to various aspects of the fundamentals of nanotechnology based drug delivery systems and the application of these systems for the delivery of small molecules, proteins, peptides, oligonucleotides and genes.

It examines five prestigious, comprehensive cancer centers based in the US, covering how these centers started their programs, what they are currently doing, and recommendations for starting integrative medicine clinics. The book also discusses the potential harm of alternative and complementary medicine, legal issues, and how to communicate with patients.
Steroids is a thematic volume from the classic Academic Press series, Vitamins and Hormones. Gerald Litwack, the new editor of this prestigious serial, brings together leading contributors to the study of steroids. These structurally and functionally complex molecules are of interest to a broad cross-section of endocrinologist, cell biologists, and biochemists. Reviews include studies of structure, function, and regulation of steroid production and action. Thus, Vitamins and Hormones continues to publish cutting-edge reviews of interest to endocrinologists and biochemists. Others will increasingly turn to this continuing series for comprehensive reviews by leading researchers in this and related disciplines.
Because progress in the field of transporters has been extraordinary, this volume will focus on recent advances in our understanding of the structure, function, physiology, and molecular biology of membrane transporters. There will be an emphasis on transporters as molecular targets for drug delivery and disposition in the body.
About 8000 clinical trials are undertaken annually in all areas of medicine, from the treatment of acne to the prevention of cancer. Correct interpretation of the data from such trials depends largely on adequate design and on performing the appropriate statistical analyses. In this book, the statistical aspects of both the design and analysis of trials are described, with particular emphasis on recently developed methods of analysis.

Antifolates are an important class of anticancer drugs originally developed as anti leu- kemic agents, but now used, usually in combination with other drugs, for the treatment of a wide range of tumors, notably carcinomas of the head and neck, breast, germ cell tumors, non-Hodgkin's lymphoma, acute lymphoblastic leukemia, and osteogenic sar- comas. 5-Fluorouracil and its prodrugs also target, in part, the folate-dependent enzyme, thymidylate synthase. Furthermore, folate supplementation in the form of leucovorin, modulates 5-fluororuacil activity. 5-Fluorouracil is widely used in the treatment of colorectal and gastric cancer and in combination for other solid tumors such as breast and head and neck cancers. Ongoing clinical trials with the newer antifolates suggest that the range of solid tumors where these agents will be of use may broaden further. Half a century ago, interesting scientific and clinical discoveries suggested that folie acid was a vitamin involved in vital cellular metabolic processes. The folate analogs, aminopterin and methotrexate, were synthesized by the American Cyanamid Company in an attempt to interfere with these processes and were shown to have anticancer activity by Farber and his colleagues. Hence, the principle of antimetabolite therapy for the treatment of cancer was established. Biomedical research over the following years led to a deeper understanding of the complex biochemical pharmacology of folates and antifolates. Selective antimicrobial agents were discovered, but more tumor-selective anticancer agents did not immediately emerge.
Drug development today needs to balance agility, speed, and risk in defining probability of success for molecules, mechanisms, and therapeutic concepts. New techniques such as fMRI promise to be part of a sequence that could transform drug development. Although numerous review articles exist that discuss the use of imaging in drug development, no one source is available that combines the various techniques and includes a discussion of disease mapping. Imaging in CNS Drug Discovery and Development, Implications for Disease and Therapy will serve to distill the most salient developments in the use of imaging in drug development and disease mapping. It will launch evolving concepts that integrate new imaging technologies and paradigms with molecular medicine and molecular profiling ("monics") as well as consider the ethical issues that arise as a result of disease or state diagnosis and the use of imaging in the public eye.

My journey into this fascinating field of biotechnology started about 26 years ago at a small biotechnology company in South San Francisco called Genentech. I was very fortunate to work for the company that begat the biotech industry during its formative years. This experience established a solid foundation from which I could grow in both the science and business of biotechnology. After my fourth year of working on Oyster Point Boulevard, a close friend and colleague left Genentech to join a start-up biotechnology company. Later, he approached me to leave and join him in of all places - Oklahoma. He persisted for at least a year before I seriously considered his proposal. After listening to their plans, the opportunity suddenly became more and more intriguing. Finally, I took the plunge and joined this ent- preneurial team in cofounding and growing a start-up biotechnology company. Making that fateful decision to leave the security of a larger company was extremely difficult, but it turned out to be the beginning of an entrepreneurial career that forever changed how I viewed the biotechnology industry. Since that time, I have been fortunate to have cofounded two other biotechnology com- nies and even participated in taking one of them public. During my career in these start-ups, I held a variety of positions, from directing the science, operations, regulatory, and marketing components, to subsequently becoming CEO.
This volume comprehensively covers the multiplicity and diversity of mechanisms underlying patient resistance to currently approved anti-cancer drugs, including tyrosine kinase inhibitors and monoclonal antibodies, blockers of growth factor receptors and their downstream pathways, which play essential functions in cancer progression. Each chapter will cover a specific group of targets and the cognate drugs, along with molecular modes of innate and evolving resistance.

Areas of focus include analytical and formulation issues, process monitoring and control, as well as post-lyophilization analysis. Written for the Methods in Pharmacology and Toxicology series, chapters include the type of expert advice that leads to superior results in the lab. Authoritative and practical, Lyophilization of Pharmaceuticals and Biologicals: New Technologies and Approaches serves as an ideal guide for researchers working in or just seeking an update on this rapidly changing field.
"Clostridium difficile" has been recognized as the cause of a broad spectrum of enteric disease ranging from mild antibiotic-associated diarrhea to pseudomembranous colitis. This volume gives new insights into the microbiology, diagnostics and epidemiology of "Clostridium difficile" and describes recent strategies in treatment of diseases caused by this agent. Main parts of the volume are devoted to "Clostridium difficile" toxins A and B which are the major virulence factors. The molecular biology, biochemistry, pharmacology and cell biology of these toxins which are the prototypes of a new family of large clostridial cytotoxins is described in great detail. "Clostridium difficile" toxins act as glucosyltransferases to inactivate small GTP-binding proteins of the Rho family which are involved in regulation of the actin cytoskeleton, cell adhesion and various signaling processes.
There are only very few chemical classes of antibiotics in medical use, and these have originated over a span of more than 60 years of research. Almost half a century ago, the first member of the macrolides, erythromycin, was introduced as a treatment option for bacterial infections. Erythromycin is a very complex fermentation product obtained from the soil bacterium Saccharopolyspora ery thraea (originally named Streptomyces erythreus). The success of erythromycin, based on its efficacy and tolerability, stimulated researchers throughout the world to undertake intense efforts to understand the biology and chemistry of macrolides and to use this experience to improve the properties of this compound class. The second generation of macrolides, based on chemical modifications of erythromy cin, is currently being in broad use, especially for treatment of respiratory tract infections. We presently foresee the introduction of a new generation of macro lides, i. e. the ketolides, which have the potential to overcome rising resistance problems. This monograph is intended to give the interested reader an overview on "macrolide experience," covering important areas from basic research to clinical use. Starting from a historic overview, the essential basic parameters - efficacy, pharmacokinetics, pharmacodynamics, and pharmacology - are highlighted in order to introduce the reader to the rationale for clinical use of macrolides. The following group of chapters cover the complex chemistry of the macro lactone structures, giving historic background, basic structure-activity relation ships of various derivatization strategies, and perspectives for future discovery of new semisynthetic macrolide antibiotics."
