Completely revised new edition of the definitive reference on disorders of hemoglobin.

Hemoglobin and Hemoglobinologists This volume, Hemoglobin Disorders: Molecular Methods and Protocols, will be introduced with a review of the great milestones in the field, and the scientists responsible for those achievements. The history of hemoglobin can be divided into three periods: the Classical period, the Modern period, and the Post-Modern period. I am inclined to include as the four major members of the classical period Francis Roughton, Quentin Gibson, Jeffries Wyman, and Linus Pauling, not only because of their achievements, but also because of the superb scientists they trained and/or influenced. Francis John Worsely Roughton (1899–1972) (Fig. 1), in his laboratory at Trinity College in Cambridge, England, made the first measurements of the rapid reaction of oxygen with hemoglobin at the millisecond scale, at first by flow-mixing methods and later by flash photolysis. He not only opened an era of molecular research of hemoglobin, but also invented the methodology for fast reactions through the use of laser technology, which was later improved by others so that even faster reactions could be detected. Another contribution of Roughton was the education of Quentin H. Gibson (Fig. 2), his favorite s- dent, who, in his laboratory in Sheffield, continued to expand the horizon of ligand binding to hemoglobin, defining the oxygen binding constants for each of the hemes of hemoglobin. Though this did not, as expected, solve the und- lying mechanism of ligand cooperativity as discussed below, it was nonet- less an important milestone.

Individuals who donate their blood provide a unique and precious gift in an act of human solidarity. In order to donate blood, prospective donors should be in good health and free from any infections that can be transmitted through transfusion. Most blood donors perceive themselves to be healthy, but some are unsuitable to donate blood due to the potential risk of compromising or worsening their own health or the risk of transmission of infections to patients. Blood transfusion services (BTS) have a duty of care towards blood donors as well as to the recipients of transfusion. This duty of care extends to prospective donors who are deferred from donation--whether on a temporary or permanent basis--as well as those who donate blood and are subsequently found to have unusual or abnormal test results. BTS have a responsibility to confirm test results and provide information, counseling and support to enable these individuals to understand and respond to unexpected information about their health or risk status. Counseling is part of the spectrum of care that a BTS should be able to provide to blood donors--including referral to medical practitioners or specialist clinical services. Pre-donation counseling was recognized as one element of the strategy to reduce and, if possible, prevent the donation of blood by individuals who might be at risk for HIV and other TTI including hepatitis B and C viruses as well as to inform the donor of the donation process and testing of blood for HIV. Post-donation counseling was acknowledged to be a necessary element of donor management as an adjunct to informing donors of unusual or abnormal test results. Blood donor counseling by trained specialist staff is now considered to be a key component of the blood system in most countries with a well-developed blood transfusion service. It may be required at a number of stages in the blood donation process or following blood screening and should be available at any point at which the BTS has an interface with donors. In many countries, however, blood donor counseling is not yet available in a structured way. Blood Donor Counselling: Implementation Guidelines has therefore been developed to provide guidance to blood transfusion services that have not yet established donor counseling programs.

This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Provides a synthesis of our current understanding of hemoglobin (Hb) function and evolution, and illustrates how research on this protein has provided more general insights into mechanisms of protein evolution and biochemical adaptation.

An updated, essential guide for the laboratory diagnosis of haemoglobin disorders This revised and updated third edition of Haemoglobinopathy Diagnosis offers a comprehensive review of the practical information needed for an understanding of the laboratory diagnosis of haemoglobin disorders. Written in a concise and approachable format, the book includes an overview of clinical and laboratory features of these disorders. The author focuses on the selection, performance, and interpretation of the tests that are offered by the majority of diagnostic laboratories. The book also explains when more specialist tests are required and explores what specialist referral centres will accomplish. The information on diagnosis is set in a clinical context. The third edition is written by a leading haematologist with a reputation for educational excellence. Designed as a practical resource, the book is filled with illustrative examples and helpful questions that can aide in the retention of the material presented. Additionally, the author includes information on the most recent advances in the field. This important text: • Contains a practical, highly illustrated, approach to the laboratory diagnosis of haemoglobin disorders • Includes “test-yourself” questions and provides an indispensable tool for learning and teaching • Presents new material on antenatal screening/prenatal diagnostic services • Offers myriad self-assessment case studies that are ideal for the trainee Written for trainees and residents in haematology, practicing haematologists, and laboratory scientists, Haemoglobinopathy Diagnosis is an essential reference and learning tool that provides a clear basis for understanding the diagnosis of haemoglobin disorders.
