Next Free Book Promotion Saturday, March 11, 2023, from 12:00 AM to 11:59 PM PST (USA) Have you ever heard the word ABO+logy? Probably not. We invented the term to cover diverse ABO topics in various research fields. However, you may have heard ABO matching is critical for safe blood transfusion. You may have also learned about the inheritance of ABO blood groups in a biology class. Surprisingly, these are just the tip of the iceberg. You can find ABO topics in many areas of biology and medicine. These include transfusion, transplantation, immunohematology, immunology, genetics, population genetics, molecular biology, cancer research, forensic science, and even molecular and species evolution studies. Well, do you know your ABO type? The answer may be yes if you have ever received a blood transfusion or donated blood. Otherwise, you may need to learn it. Well, do you see the differences between type A and type B? How about a relationship between ABO blood types and diseases (cancer, malaria, economy class syndrome, COVID-19, etc.)? Do you know ABO blood groups are important in crime scene investigation (CSI) and paternity tests? Are you interested in ABO-type diets or ABO's association with personality? Before answering these questions, let us learn more about ABO blood groups. Through ABO studies, students can learn biology in an organized manner instead of simply adding separate branches. Therefore, it will be ideal to use this book as a supplemental text in a biology class to strengthen biological learning. In addition to students, this book may also be suitable for adults with scientific interests in biomedicine. [Contents] Introduction Chapter 1 Basics of ABO blood groups Chapter 2 Genetic inheritance and genes Chapter 3 From cells to individuals Chapter 4 Cell division and differentiation Chapter 5 Genetic polymorphism Chapter 6 Materials and energy Chapter 7 Genetic information and DNA Chapter 8 RNA and proteins Chapter 9 Sugars and sugar chains Chapter 10 Glycosyltransferases and sugar chain biosynthesis Chapter 11 Cloning blood group ABO gene Chapter 12 ABO gene and mutations Chapter 13 A and B glycosyltransferases Chapter 14 Evolution of ABO genes Chapter 15 Genes encoding ABO-related glycosyltransferases Chapter 16 Immunity Chapter 17 ABO blood groups and diseases Chapter 18 ABO blood groups and pseudoscience Epilogue Most chapters summarize current knowledge. However, several chapters describe our research, trying to fascinate readers with basic and clinical research. In addition, we repeatedly explained specific topics under different contexts to emphasize their importance. We recommend that readers rapidly read through the book in a couple of days before reading it thoroughly. We briefly mentioned some subjects when they appeared for the first time but later explained in detail. This rapid reading will help readers grasp the full scope of the book without being lost in translation with complicated technical terms. Keywords and crucial sentences are written in bold and italicized, respectively. To define scientific and technical terms, we extensively used Wikipedia. That is why we established links between the essential keywords and the corresponding web pages on Wikipedia for easy access to references, which will be helpful in thorough reading. This book is packed with helpful information. We hope that readers enjoy reading to enhance their knowledge.
