The AIDS Pandemic explores the ways in which HIV/AIDS has, and
continues to transform the wide range of related disciplines it
touches. Novel perspectives are provided by a unique panel of
internationally recognised experts who cover the unprecedented
impact onf AIDS on culture, demographics and politics around the
world, including how it affected the worlds' economy, health
sciences, epidemiology and public health. This important far-
reaching analysis uses the lessons learned from a wide array of
disciplines to help us understand the current status and evolution
of the pandemic, as it continues to evolve.
The study of the molecular events leading to cellular transformation and cancer has progressed significantly in the last decade, and it has become apparent that many genes subject to modification in cancer are, in fact, transcription factors that govern the execution of the genetic programme of the cell. Transcription factors can behave either as oncogenes or as tumour suppressor genes. To date only a limited number of transcription factors have been associated with cancer. This volume deals with several transcription factor families that were first identified in oncogenic retroviruses. Each chapter contains a description of the structure of the transcription factors, the nature of target genes, the regulation of their activities, and an explaination of how they can deregulate cell growth and differentiation. This text should be suitable for the specialist scientist and the advanced student
Retinoids have received considerable attention in recent years and due cognizance has been given to their versatility as biological response modifiers, as evidenced by the virtually explosive growth of literature in this field in the past few years. This volume has been designed to give a current state-of-the-art picture of retinoids. The perceived potential of retinoids in the treatment of certain disease stated has initiated attempts at identifying and synthesizing new retinoid derivatives with definable and selective effects on aberrant biological phenomena. Appropriately, therefore, we begin with the chemistry of retinoids and their derivatives together with discussions of their biological activity. Major advances have been made in understanding the mechanisms by which retinoids modulate physiological and phenotypic traits of cells. The transduction of retinoid signaling by the mediation of nuclear receptors of the steroid/thyroid receptor superfamily has now been studied extensively and the cloning and defining the characteristics of these receptors has been a focus of discussion in this volume. Retinoids also markedly modulate the transduction of extracellular signals such as those imparted by growth factors and hormones, and thus actively influence and control cellular proliferative patterns. Retinoids can alter epidermal growth factor receptor expression (Kawaguchi et al., 1994), responsiveness to thyroid hormone (Esfandiari et al., 1994; Pallet et al., 1994), inhibit the proliferative responses of hematopoietic progenitor cells to granulocyte colony stimulating factor (Smeland et al., 1994), and modulate secretion on interleukins by leukaemic cells (Balitrand et al., 1994), among other things. This has obvious implications for pharmacological manipulation of deregulated growth (Dickens and Colletta, 1993; Mulshine et al., 1993). Apoptosis is another component in the regulation of growth control. Apoptotic cell death is influenced by several agents and retinoids may function by interfering with apoptotic pathways of regulation of growth control and quite legitimately, therefore, the importance of this aspect of retinoid function has been duly recognized here.

This book addresses the most important aspects of how to plan and evaluate clinical trials with a composite primary endpoint to guarantee a clinically meaningful and valid interpretation of the results. Composite endpoints are often used as primary efficacy variables for clinical trials, particularly in the fields of oncology and cardiology. These endpoints combine several variables of interest within a single composite measure, and as a result, all variables that are of major clinical relevance can be considered in the primary analysis without the need to adjust for multiplicity. Moreover, composite endpoints are intended to increase the size of the expected effects thus making clinical trials more powerful. The book offers practical advice for statisticians and medical experts involved in the planning and analysis of clinical trials. For readers who are mainly interested in the application of the methods, all the approaches are illustrated with real-world clinical trial examples, and the software codes required for fast and easy implementation are provided. The book also discusses all the methods in the context of relevant guidelines related to the topic. To benefit most from the book, readers should be familiar with the principles of clinical trials and basic statistical methods.

Authoritative and practical, Duchenne Muscular Dystrophy: Methods and Protocols serves as a guide for researchers exploring the complicated nature of dystrophin in the hope of helping the victims of this disorder.
This book advocates the importance and value of errors for the progress of scientific research! Hans Kricheldorf explains that most of the great scientific achievements are based on an iterative process (an 'innate self-healing mechanism'): errors are committed, being checked over and over again, through which finally new findings and knowledge can arise. New ideas are often first confronted with refusal. This is so not only in real life, but also in scientific and medical research. The author outlines in this book how great ideas had to ripen over time before winning recognition and being accepted. The book showcases in an entertaining way, but without schadenfreude, that even some of the most famous discoverers may appear in completely different light, when regarding errors they have committed in their work. This book is divided into two parts. The first part creates a fundament for the discussion and understanding by introducing important concepts, terms and definitions, such as (natural) sciences and scientific research, laws of nature, paradigm shift, and progress (in science). It compares natural sciences with other scientific disciplines, such as historical research or sociology, and examines the question if scientific research can generate knowledge of permanent validity. The second part contains a collection of famous fallacies and errors from medicine, biology, chemistry, physics and geology, and how they were corrected. Readers will be astonished and intrigued what meanders had to be explored in some cases before scientists realized facts, which are today's standard and state-of-the-art of science and technology. This is an entertaining and amusing, but also highly informative book not only for scientists and specialists, but for everybody interested in science, research, their progress, and their history!
This edited volume is a definitive text on adaptive clinical trial designs from creation and customization to utilization. As this book covers the full spectrum of topics involved in the adaptive designs arena, it will serve as a valuable reference for researchers working in industry, government and academia. The target audience is anyone involved in the planning and execution of clinical trials, in particular, statisticians, clinicians, pharmacometricians, clinical operation specialists, drug supply managers, and infrastructure providers. In spite of the increased efficiency of adaptive trials in saving costs and time, ultimately getting drugs to patients sooner, their adoption in clinical development is still relatively low. One of the chief reasons is the higher complexity of adaptive design trials as compared to traditional trials. Barriers to the use of clinical trials with adaptive features include the concerns about the integrity of study design and conduct, the risk of regulatory non-acceptance, the need for an advanced infrastructure for complex randomization and clinical supply scenarios, change management for process and behavior modifications, extensive resource requirements for the planning and design of adaptive trials and the potential to relegate key decision makings to outside entities. There have been limited publications that address these practical considerations and recommend best practices and solutions. This book fills this publication gap, providing guidance on practical considerations for adaptive trial design and implementation. The book comprises three parts: Part I focuses on practical considerations from a design perspective, whereas Part II delineates practical considerations related to the implementation of adaptive trials. Putting it all together, Part III presents four illustrative case studies ranging from description and discussion of specific adaptive trial design considerations to the logistic and regulatory issues faced in trial implementation. Bringing together the expertise of leading key opinion leaders from pharmaceutical industry, academia, and regulatory agencies, this book provides a balanced and comprehensive coverage of practical considerations for adaptive trial design and implementation.

This edited work presents studies that clarify the basics of producing recombinant enzymes that finally lead to commercialization. It enables researchers to see what is crucial to the commercialization process, from examining the cloning method, using analytical techniques such as calculating the total protein content and enzyme activity, through considering upstream and downstream processes, to the final product. Readers will discover the importance of the cloning method as it influences the upstream and downstream processes and determines the level of success of the recombinant enzyme commercialization processes. We see that the two main factors that are particularly sensitive during the cloning process are the vector and the host. A discussion of analytical techniques is presented followed by studies on important stages during the upstream processes including the process of optimizing the media to get results and high enzyme activity. Downstream processes such as the cell disruption technique, purification and formulation of the final product are then considered. The reader is introduced to software that helps streamline recombinant enzyme production from the upstream to downstream processes, to facilitate the process of up-scaling production. This work includes a case study as tool, to guide understanding of the commercialization process. The work is written for researchers in the field and is especially suited to those who are under pressure to embark on the tough process of commercialization.

Allergy is developing into one of the most prevalent diseases affecting individuals in the very early days of life. While the cause of this epidemic is still unclear, it appears that the westernized life style is playing an important role, which includes nutrition, possibly air pollution as well as hygienic conditions. While epidemiologic studies were able to narrow down these factors, basic research discovered novel mechanisms that control the organisms tolerance against allergens. Particularly interesting is the role of microorganisms that colonize or infect a host and thereby cause damage and immunological activation followed by sensitization or exacerbation of already existing sensitizations. However at the same time microbial activation of the immune system can help to generate a protective immunity that prevents allergen sensitization. The current book is collecting these evidences and connects epidemiologic and clinical mechanistic knowledge. Only the synthesis of this knowledge will help to find solutions to the ongoing allergy epidemic in terms of public health activities, prevention and therapy.

The book offers an essential guide for medical scientists interested in developing aptamer-based schemes for better theranostics. It is therefore of interest for not only academic researchers, but also practitioners and medical researchers in various fields of medical science, medical research and bio-analytical chemistry.
The blood system is multi-scale, from the organism to the organs to cells to intracellular signaling pathways to macromolecule interactions. Blood consists of circulating cells, cellular fragments (platelets and microparticles), and plasma macromolecules. Blood cells and their fragments result from a highly-ordered process, hematopoiesis. Definitive hematopoiesis occurs in the bone marrow, where pluripotential stem cells give rise to multiple lineages of highly specialized cells. Highly-productive and continuously regenerative, hematopoiesis requires a microenvironment of mesenchymal cells and blood vessels. A Systems Biology Approach to Blood is divided into three main sections: basic components, physiological processes, and clinical applications. Using blood as a window, one can study health and disease through this unique tool box with reactive biological fluids that mirrors the prevailing hemodynamics of the vessel walls and the various blood cell types. Many blood diseases, rare and common can and have been exploited using systems biology approaches with successful results and therefore ideal models for systems medicine. More importantly, hematopoiesis offers one of the best studied systems with insight into stem cell biology, cellular interaction, development; linage programing and reprograming that are every day influenced by the most mature and understood regulatory networks.

MILS-13 provides an up-to-date review on the relationships between essential metals and human diseases, covering 13 metals and 3 metalloids: The bulk metals sodium, potassium, magnesium, and calcium, plus the trace elements manganese, iron, cobalt, copper, zinc, molybdenum, and selenium, all of which are essential for life. Also covered are chromium, vanadium, nickel, silicon, and arsenic, which have been proposed as being essential for humans in the 2nd half of the last century. However, if at all, they are needed only in ultra-trace amounts, and because of their prevalence in the environment, it has been difficult to prove whether or not they are required. In any case, all these elements are toxic in higher concentrations and therefore, transport and cellular concentrations of at least the essential ones, are tightly controlled; hence, their homeostasis and role for life, including deficiency or overload, and their links to illnesses, including cancer and neurological disorders, are thoroughly discussed. Indeed, it is an old wisdom that metals are indispensable for life. Therefore, Volume 13 provides in an authoritative and timely manner in 16 stimulating chapters, written by 29 internationally recognized experts from 7 nations, and supported by more than 2750 references, and over 20 tables and 80 illustrations, many in color, a most up-to-date view on the vibrant research area of the Interrelations between Essential Metal Ions and Human Diseases. |
