380 years ago, in the year 1614, Ubbo Emmius transplanted the gene ofscience from Ostfriesland into the education genome ofthe city ofGroningen as devel- oped by Regnerus Praedinius. He thereby founded the University ofGroningen. It is with great pleasure that the Faculty of Medicine as one of the founding faculties ofour University, welcomes you to this 19th International Symposium ofBloodTransfusion, whichwill coverthe themeofHereditaryDiseasesandtheir relation to Transfusion Medicine, where cell expansion, gene transfer and gene therapy are the read thread. Since the earlydays there has beena specificand sincere interest in inborn errors ofmetabolism and hereditarydisorders. This interest has resulted in a structured research, diagnostic and counselling facilities, and therapeuticapproaches where various disciplines within our faculty work closely together with groups from related faculties of the University of Groningen, as well as other national and international scientific institutions. The field of inborn errors, genetic abnormalities and mutations, and hereditary diseases covers a broad gamma of extremely interesting and exciting scientific aspects,whichrangefrom clearphysicalaberrationstomolecularanalysisofgenes and genomes, coding areas and amino acid sequences. It is intriguing to realise that the balance of life seemingly depends on the position or presence of one single molecule as a part ofthe total complex ofgenetic information in the cell.
Micro and Nano Flow Systems for Bioanalysis addresses the latest developments in biomedical engineering at very small scales. It shows how organic systems require multi-scale understanding in the broadest sensewhether the approach is experimental or mathematical, and whether the physiological state is healthy or diseased. Micro-and nano-fluidics represent key areas of translational research in which state-of-the-art engineering processes and devices are applied to bedside monitoring and treatment. By applying conventional micro- and nano-engineering to complex organic solids, fluids, and their interactions, leading researchers from throughout the world describe methods and techniques with great potential for use in medicine and clinical practice. Coverage includes the seeming plethora of new, fine-scale optical methods for measuring blood flow as well as endothelial activation and interaction with tissue. Generic areas of modeling and bioelectronics are also considered. In keeping with the recurring theme of medicine and clinical practice, approximately half of the chapters focus on the specific application of micro- and nano- flow systems to the understanding and treatment of cancer and cardiovascular diseases. This book developed from an Expert Overview Session on "Micro & Nano Flows in Medicine: the way ahead" at the 3rd Micro and Nano Flows Conference (MNF2011) held in Thessaloniki, Greece. Additional chapters were included to enhance the international, state-of-the-art coverage.
Point of care testing (POCT) is a new concept in laboratory medicine that is widely used at present. It is the new advent that helps ease medical care in the present day. The knowledge on the POCT medicine is very important and necessary for the general practitioner. In this specific book, the author summarizes, presents and discusses on the concept of POCT, its importance and examples of important POCT tools.

Since the establishment of the DNA structure researchers have been highly interested in the molecular basis of the inheritance of genes and of genetic disorders. Scientific investigations of the last two decades have shown that, in addition to oncogenic viruses and signalling pathways alterations, genomic instability is important in the development of cancer. This view is supported by the findings that aneuploidy, which results from chromosome instability, is one of the hallmarks of cancer cells. Chromosomal instability also underpins our fundamental principles of understanding tumourigenesis: It thought that cancer arises from the sequential acquisition of genetic alterations in specific genes. In this hypothesis, these rare genetic events represent rate-limiting 'bottlenecks' in the clonal evolution of a cancer, and pre-cancerous cells can evolve into neoplastic cells through the acquisition of somatic mutations. This book is written by international leading scientists in the field of genome stability. Chapters are devoted to genome stability and anti-cancer drug targets, histone modifications, chromatin factors, DNA repair, apoptosis and many other key areas of research. The chapters give insights into the newest development of the genome stability and human diseases and bring the current understanding of the mechanisms leading to chromosome instability and their potential for clinical impact to the reader.
Scientists are coming under increasing pressure from activist groups to stop animal experimentation, branded as cruel and unnecessary for improving human health. This attitude, however, stems from an unrealistic evaluation of the situation and distorted information about present scientific knowledge. There is no question that most medical progress - perhaps all, in fac- has been attained through knowledge derived initially from experiments in various animal species. There is practically no way of replacing animals in these investigations and so-called 'alternative methods' are in reality merely complementary. Tissue cultures, cell, microorganisms, enzymes, membranes, mathematical models - all are useful for preliminary screening tests and for testing hypotheses, but the complexity of a living organism is such that in vivo studies are essential before any test can responsibly be made in man. This book presents the proceedings of an international symposium organized in Strasbourg (October 24-25, 1988), with the aim of assessing present-day requirements as regards animal experimentation in research related to major medical and toxicological problems still awaiting solutions.
In a perfect world, after their clinical rotation, CLSs and MLTs will be working in all four areas of study of medical technology (Microbiology, Chemistry, Hematology and Immunohematology), retain all that they know and live and work happily ever after. But as we all know that is far from the case, more frequently than not, a CLS or MLT will be stuck in one or two specialized area of study. Mycology is a unique sub-subspecialty of Microbiology that both the macroscopic and microscopic part of it require years of experience for a CLS to feel a high level of confidence. CLSs who had been away from the Mycology department for a period of time or never had a chance to work in the Mycology department will need a good refresher course before venturing into this department. This manual does not claim to be able to boost someone's confidence overnight or claim to have all the answers, but instead this manual serves as a guide to re-discovering what one previously knew. My hope is that this manual will serve its purpose and be a source of confidence to those who are brave enough to venture out in the mycology department as a newbee or someone who had been away from it for a period of time.
Blood transfusion is considered a life-saving therapy since ancient times, but, at the same time, a high-risk procedure. Nowadays the common perception is that infection is the greatest risk, even if the blood has never been safer from this point of view. Currently, the residual risk of transfusion must be related mainly to immunological mechanisms underlying to AB0 and minor blood systems, to compatibility of blood transfused and to development of irregular antibodies in transfused patients. "Transfusion Medicine and Patient Safety" aims to provide the basic of immunohematology to readers and to analyze the transfusional process highlighting the most critical points, thus more exposed to errors. Screening on blood and blood components for infectious diseases along with the surveillance action on emerging viruses results in the drastic reduction of post-transfusion infection, together with the potential to further increase the level of security from infection through the inactivation of blood components. The text also describes the major diagnostic systems and organizational models that modern technology provides us with a correct immunohematological diagnosis and an appropriate trasfusional therapy.
The goal of clinical laboratories is to produce accurate information for clinical decision making in medicine. More than half of the medical decisions made depend on clinical laboratory tests. Patient safety represents an important and critical problem for laboratories. They need to assure that the information they deliver to physicians is accurate, and therefore safe for clinicians to use. Endogenous compounds can interfere with laboratory tests, decreasing accuracy and threatening patient safety. Elevated bilirubin (bilirubinemia) and elevated lipids (lipemia) are common conditions that cause significant interferences with laboratory results. Clinicians depend on laboratories to detect these endogenous interferences. Laboratories must have a means to detect these endogenous interferences, make decisions about reporting results, and evaluate their impact. Most clinical pathology books provide only an abbreviated introduction to the subject, or provide a long list of references, without the necessary foundation for evaluating their significance. Package inserts typically provide scant information. This book provides the empirical and theoretical foundation for these interferences, describes the clinical settings where they occur, and explains their evaluation and detection, allowing the laboratory to interpret the available data on interferences and make the appropriate decision to effectively report test results while protecting patient safety.

The present work is an attempt to provide a systematic treatment of genetic linkage in diploid heredity. Part A presents a general account of statistical methods which can be brought to bear on the problem. The primary emphasis is on the practical aspects of estimation. A large proportion, if not the majority, of mutant genes fail to match up to 'textbook' genes-with faultless segregation ratios and expression-yet, these are the materials with which the practical researcher has to cope. For this reason, it is important to know how to deal with the assortment of genes which may display significant deviations from expectation. Part B examines the accumulated data on linkage for most of the laboratory mammals and provides a comprehensive and up-to-date survey. The need for a critical review has often been expressed and it is hoped that the present analysis will fill the gap. The volume of material is probably the most important in the animal kingdom other than that for Drosophila species.
Cell Surface Receptors: A Short Course on Theory and Methods, Second Edition is a primer for the study of cell surface receptors. The simplified discussion of methods and their underlying principles removes the usual intimidation caused by the specialized vocabulary or sophisticated mathematics that characterize many of the primary papers in this field. In this way, the basic concepts become emphasized. This volume is a starting point: a textbook as well as a manual to which the investigator can return for a refresher course, when needed.
Given the vital importance of immune system research, the gathering of clear, consistent, and informative protocols involving the study of dendritic cells is paramount. Bringing the popular first edition fully up to date, Dendritic Cell Protocols, Second Edition presents protocols from experts in the field that cover the basics and more complex forays into the exploration of DC development and function, both in mice and humans. The first section of the volume involving humans explores topics such as the isolation of blood DC subtypes, primary skin Langerhans cells, and the generation of gene-manipulated human DCs with the inclusion of more clinically relevant methods as well, while the second section involving rodent models delves into DC and precursor generation in vitro, isolation ex vivo, disease models, as well as DC functions and properties. Written in the highly successful Methods in Molecular Biology (TM) series style, chapters include introductions to their respective subjects, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Comprehensive and cutting-edge, Dendritic Cell Protocols, Second Edition aims to become a bench-side handbook for both beginners and experts in the field of DC research and a long-term reference for some of the most popular methods put forward by those who lead the field.

While the historic roots of clinical chemistry originate from the chemical sciences the growth of the subject has been dependent upon the poli tical, social, economic and technologic national soil in which it has developed. Thus the present leaders in this field have backgrounds variously in chemistry, medicine, pharmacy or sometimes biology. Today, clinical chemistry has attained stature as a unified independent discipline. It is characterized by active and productive international and national societies; its function codified in the law of many countries; its scientific content the sole subject of international and national journals as well as textbooks and educational programs; and its inter national, regional and national meetings have become focal points for major exchange of scientific, clinical and technical information and exhibition. The positive impact of the discipline upon the delivery of health care has given it a significant position in the economics of public health. As a consequence it has become the most rapidly-growing segment of the industrial and commercial component of health main tenance. These changes have brought the need to define the educational and training processes to prepare future leaders of clinical chemistry. The diverse backgrounds of the present directors of clinical chemicallabora tories has required that the viewpoints of chemists, pharmacists, physicians and biologists be brought into harmony. This has been achieved by the years of discussion, debate and review by colleagues of varied professional backgrounds. This monograph reflects their consensus viewpoint for the practice of clinical chemistry at its most advanced level."
The unexpected and premature passing away of Professor Ebrahim H. "Abe" Mamdani on January, 22, 2010, was a big shock to the scientific community, to all his friends and colleagues around the world, and to his close relatives. Professor Mamdani was a remarkable figure in the academic world, as he contributed to so many areas of science and technology. Of great relevance are his latest thoughts and ideas on the study of language and its handling by computers. The fuzzy logic community is particularly indebted to Abe Mamdani (1941-2010) who, in 1975, in his famous paper An Experiment in Linguistic Synthesis with a Fuzzy Logic Controller, jointly written with his student Sedrak Assilian, introduced the novel idea of fuzzy control. This was an elegant engineering approach to the modeling and control of complex processes for which mathematical models were unknown or too difficult to build, yet they could effectively and efficiently be controlled by human operators. This ground-breaking idea has found innumerable applications and can be considered as one of the main factors for the proliferation and adoption of fuzzy logic technology. Professor Mamdani's own life and vital experience are illustrative of his "never surrendering" attitude while facing adversaries, which is normal for a person proposing any novel solution, and represent a great example for everybody. His subtle sense of humor, his joy for life, and his will to critically help people, especially young people, were characteristics deeply appreciated by all the people who enjoyed and benefited from his friendship and advice. This book constitutes a posthumous homage to Abe Mamdani. It is a collection of original papers related in some way to his works, ideas and vision, and especially written by researchers directly acquainted with him or with his work. The underlying goal of this book will be fulfilled if, in the very spirit of Mamdani's legacy, the papers will trigger a scientific or philosophical debate on the issues covered, or contribute to a cross-fertilization of ideas in the various fields.
The Raman effect is a most useful tool for the study of molecular vibrations and molecular structure. Information about the structure and symmetry of molecules, as well as about their vibrational energies can be obtained to a reasonable degree of satisfaction from their infrared and Raman vibrational spectra. The body of knowl edqe of the vibrational infrared and Raman spectra of molecules is immense and is now so well organized and understood that it is found to be represented in any stan dard upper level undergraduate curriculum in chemistry. The rotational energies of a molecule and quantitative details about its structure can only be obtained through the techniques of microwave, and high-resolution infrared and Raman spectroscopy of low pressure gases and vapors. The results of such investigations are of interest . not only to the academic scientists, but also to scientists and engineers who are active in applied fields of chemistry and physics, as well as the atmospheric sciences. This book deals with basic investigations of the Raman scattering of light by gases, with some attention also being given to liquid substances. After a brief in troductory chapter that delineates the historical development of Raman spectroscopy of gases, high-resolution rotation-vibrational and pure rotational Raman spectros copy is described in Chapters 2 and 3. The all-important intensity parameter, the Raman scattering cross section, is treated in Chapter 4, while the broadening of Raman lines due to the effects of intermolecular forces is taken up in Chapter 5."
Genetically-engineered mouse models for cancer research have become invaluable tools for studying cancer biology and evaluating novel therapeutic approaches. This volume focuses on state-of-the-art methods for generating, analyzing and validating such models for studying aspects of human cancer biology. Additionally, these models are emerging as important pre-clinical systems in which to test cancer prevention and therapeutic strategies in order to select compounds for testing in clinical trials.
eat shock proteins (HSPs), also called stress proteins, are not only induced in response to elevated temperatures, but also as a result of various stress situations, including environmental strains, viral H infection, ischemia, anoxia and oxidative stress. These stress situations trigger cellular defence mechanisms that act as an emergency system capable of combatting the toxic consequences due to the accumulation of misfolded proteins. Heat shock proteins are involved in many physiological processes, including development and differentiation, organisation of the cytoarchi tecture by binding to cytoskeletal elements and regulation of the balance between cell death and survival. Many heat shock proteins work as molecular chaperones. In this role, they contribute to in vivo protein folding and prevent nonproductive interactions with other proteins and cellular c- ponents. In recent years it has been found that the chaperone system and the proteolytic machinery work closely together, and that proteasomal - hibition causes the upregulation of stress proteins. Impairment of the proteasomal machinery and chaperone functions lead to protein damage, which contributes to neurodegenerative disorders and to the aging process.
With the first IVF treatments, many skeptics rejected the process due to the possibility of something going wrong. But with time, this new way of conceiving became accepted throughout the world. But there is always a danger that somebody might come up with an unethical and dangerous idea to influence the process of fetal development in order to be able to offer his or her services to the people who would be prepared to pay enormous sums and in this way endanger the lives of the innocent newborn. With time and effort, some of the ideas, impossible today, might be achievable in the future and it could go beyond our present understanding but we should be on guard that it does not go beyond our control.
