Mr. Jefferson and the Giant Moose: Natural History in Early America

by Lee Alan Dugatkin

In the years after the Revolutionary War, the fledgling republic of America was viewed by many Europeans as a degenerate backwater, populated by subspecies weak and feeble. Chief among these naysayers was the French Count and world-renowned naturalist Georges-Louis Leclerc de Buffon, who wrote that the flora and fauna of America (humans included) were inferior to European specimens. Thomas Jefferson--author of the Declaration of Independence, U. S. president, and ardent naturalist--spent years countering the French conception of American degeneracy. His Notes on Virginia systematically and scientifically dismantled Buffon's case through a series of tables and equally compelling writing on the nature of his home state. But the book did little to counter the arrogance of the French and hardly satisfied Jefferson's quest to demonstrate that his young nation was every bit the equal of a well-established Europe. Enter the giant moose. The American moose, which Jefferson claimed was so enormous a European reindeer could walk under it, became the cornerstone of his defense. Convinced that the sight of such a magnificent beast would cause Buffon to revise his claims, Jefferson had the remains of a seven-foot ungulate shipped first class from New Hampshire to Paris. Unfortunately, Buffon died before he could make any revisions to his Histoire Naturelle,but the legend of the moose makes for a fascinating tale about Jefferson's passion to prove that American nature deserved prestige. In Mr. Jefferson and the Giant Moose,Lee Alan Dugatkin vividly recreates the origin and evolution of the debates about natural history in America and, in so doing, returns the prize moose to its rightful place in American history.

MR Spectroscopy of Pediatric Brain Disorders

by Ashok Panigrahy Stefan Blüml

Magnetic resonance spectroscopy (MRS) is a modality available on most clinical MR scanners and readily integrated with standard MR imaging (MRI). For the brain in particular, MRS has been a powerful research tool providing additional clinically relevant information for several disease families such as brain tumors, metabolic disorders, and systemic diseases. The most widely-available MRS method, proton (1H; hydrogen) spectroscopy, is FDA approved for general use in the US and can be ordered by clinicians for patient studies if indicated. There are several books available that describe applications of MRS in adults. However, to the best of our knowledge there is currently no book available that focuses exclusively on applications in pediatrics. MR spectroscopy in the pediatric population is different from adults for two main reasons. Particularly in the newborn phase the brain undergoes biochemical maturation with dramatic changes of the "normal" biochemical fingerprint. Secondly, brain diseases in the pediatric population are different from adult disorders. For example, brain tumors, which are mostly gliomas in the adults, often originate from different cell types and are also more diverse even within the same type and grade of tumor. This diversity of diseases and its implications for MR spectroscopy has not been addressed sufficiently in the literature, we believe. The target audience for "MR Spectroscopy of Pediatric Brain Disorders" are thus both clinicians and researchers involved with pediatric brain disorders. This includes radiologists, neurologists, neurooncologists, neurosurgeons, and more broadly the neuroscience and neurobiology community. This book will provide the necessary background information to understand the basics of MR spectroscopy. This will be followed by a detailed discussion of the normal biochemical maturation which will highlight the metabolic differences between the pediatric and adult brain. Thereafter, in SECTION I individual chapters will address various pediatric brain disease families. Of particular importance for pediatrics are case studies. For that reason, SECTION II will contain a large number of case studies. This will be particularly important for clinicians who may want to see examples of MRS for various conditions. A standardized format will be used for case reports that allow the reader to quickly understand the history of each case presented and the significance of the findings. The case reports will also include information from other imaging modalities to point out any added value of MRS in addition to conventional studies and clinical information. This section is necessary because the format of providing more complete information about individual patients is not practical for the chapters in SECTION I.

MRI is the ideal complement to echocardiography whenever the information provided by the latter is limited. This book has been conceived as a self-teaching manual that will assist qualified radiologists, cardiologists, and pediatricians, as well as those in training. It is richly illustrated with numerous images and drawings that cover all usual and most unusual anomalies. The principal author, Professor Bruno Kastler, is head of radiology at Besançon University Hospital, France and is board certified in both radiology and cardiology.

MRI of Degenerative Disease of the Spine: A Case-Based Atlas

by Paola D'Aprile Alfredo Tarantino

This is the second edition of an acclaimed, richly illustrated and comprehensive case-based atlas focusing on MRI of degenerative changes in the osteoarticular structures of the spine. Spinal degenerative disease is highly prevalent in the general population and its incidence increases with age. At the same time, degenerative spinal conditions are one of the most common causes of pain.The book presents a comprehensive overview of the MR findings observed in degenerative disease of spinal joints, ligaments and paravertebral muscles, and offers guidance on selecting the appropriate imaging protocol, which is critical in detecting the potentially very subtle changes. The MR study protocols presented include T2-weighted sequences with fat saturation and contrast-enhanced T1-weighted sequences with fat saturation, since these sequences permit better visualization of inflammatory changes of both anterior and posterior elements of the spine.This richly illustrated second edition highlights the inflammatory component of the degenerative pathology of the spine, which in most cases is responsible for the painful symptomatology. It also discusses in detail the use of contrast medium in MRI of spinal degenerative disease. The “case-based” structure of the atlas allows easy but effective consultation by radiologists, neuroradiologists, rheumatologists, orthopedists and physiatrists, as well as students.

MRI of Gynaecological Diseases: Illustrations and Cases

by Guofu Zhang

This book systematically covers MRI imaging findings of a spectrum of gynaecological diseases, including ovarian cysts, uterine fibroids, cervical cancer, and endometrial cancer, etc. All chapters are arranged in the same format: simply clinical history is firstly presented in order to help readers mimic the real clinical scenario, and then untypical features in many common diseases and typical features in many uncommon diseases are interpreted. In the end of each chapter, tips in differential diagnosis were summarized by analysing a class of cases with similar imaging performance. All cases in the book have the detailed pathological results, and the pathological specimens are also shown in some cases. It will be an ideal reference for physicians involved in the diagnosis and treatment of gynaecological diseases.

MRI of Rectal Cancer

by Mathias Langer Arnd-Oliver Schäfer

Today magnetic resonance imaging (MRI) of rectal cancer is one of the most interesting topics in radiology. Over the last decade technical refinements have strengthened the role of MRI as a first-line diagnostic strategy for accurate staging of rectal cancer. MRI is perfectly suited to predict tumor-free circumferential resection margins. Additionally, high accuracies have been reported for the T and N stages, which is comparable to transrectal ultrasound (TRUS). Novel approaches to moving table MRI serve as a platform for thoracic, abdominal and pelvic staging of rectal cancer patients within one examination. The broad spectrum of high-quality illustrations and the contribution of clinical experts provide substantial insight into the sophisticated field of rectal cancer management.

MRI of Short and Ultrashort-T_2 Tissues: Making the Invisible Visible

by Jiang Du Graeme M. Bydder

This book comprehensively covers ultrashort echo time (UTE), zero echo time (ZTE), and other magnetic resonance imaging (MRI) acquisition techniques for imaging of short and ultrashort-T2 tissues. MRI uses a large magnet and radio waves to generate images of tissues in the body. The MRI signal is characterized by two time constants, spin-lattice relaxation time (T1) which describes how fast the longitudinal magnetization recovers to its initial value after tipping to the transverse plane, and spin-spin relaxation time (T2) which describes how fast the transverse magnetization decays. Conventional MRI techniques have been developed to image and quantify tissues with relatively long T2s. However, the body also contains many tissues and tissue components such as cortical bone, menisci, ligaments, tendons, the osteochondral junction, calcified tissues, lung parenchyma, iron containing tissues, and myelin, which have short or ultrashort-T2s. These tissues are “invisible” with conventional MRI, and their MR and tissue properties are not measurable. UTE and ZTE type sequences resolve these challenges and make these tissues visible and quantifiable.This book first introduces the basic physics of conventional MRI as well as UTE and ZTE type MRI, including radiofrequency excitation, data acquisition, and image reconstruction. A series of contrast mechanisms are then introduced and these provide high resolution, high contrast imaging of short and ultrashort-T2 tissues. A series of quantitative UTE imaging techniques are described for measurement of MR tissue properties (proton density, T1, T2, T2*, T1p,magnetization transfer, susceptibility, perfusion and diffusion). Finally, clinical applications in the musculoskeletal, neurological, pulmonary and cardiovascular systems are described.This is an ideal guide for physicists and radiologists interested in learning more about the use of UTE and ZTE type techniques for MRI of short and ultrashort-T2 tissues.

MRI of the Temporomandibular Joint: Correlation Between Imaging and Pathology

by Tiziana Robba Carlotta Tanteri Giulia Tanteri

This book is the outcome of a fruitful, long-standing cooperation between expert radiologists and clinicians, and explains the most relevant features and technical requirements that are needed to optimally conduct and assess MR examinations for temporomandibular joint (TMJ) pathologies. TMJ conditions are increasingly gaining attention, as the underlying diseases involved can vary considerably and be difficult to diagnose. Similarly, several imaging sub-specialties (e.g. dental radiology, neuroradiology, and musculoskeletal radiology) now find themselves dealing with the temporomandibular joints. The authors provide essential information on TMJ anatomy, dynamics, function and dysfunction. Correlations between clinical aspects and MRI findings are discussed and guidance for the correct interpretation of results is offered. Special findings that are helpful for differential diagnosis (arthritis, osteochondroma, synovial chondromatosis) are also examined. Given its extensive and varied coverage, the book offers a valuable asset for radiologists, dentists, gnathologists, maxillofacial surgeons, orthodontists and other professionals seeking a thorough overview of the subject

MRI of the Upper Extremity: Elbow, Wrist, and Hand

by Bethany U. Casagranda

This book systematically discusses the anatomy and pathology of three specific regions of the upper extremity: the elbow, wrist, and hand. Divided into three sections, by body part, chapters cover anatomy and pathology. The anatomy chapters give a comprehensive view of each body part and normal variants found there. Although the primary modality emphasized will be MRI, illustrations and other modalities, including plain radiograph and CT, will be used to comprehensively discuss the anatomy of each region. Liberally illustrated, the pathology chapters then cover both traumatic and non-traumatic causes for imaging and detail how to perform and interpret each MRI. Specific examples include: osseous trauma, soft tissue trauma, and tumor imaging. Chapters are written with the deliberate intention to be of value to all levels of radiology training while remaining a reliable resource for attending radiologists.

The mRNA Metabolism in Human Disease (Advances in Experimental Medicine and Biology #1157)

by Luísa Romão

The eukaryotic gene expression pathway involves a number of interlinked steps, with messenger RNA (mRNA) being the key intermediate. The precursor mRNA is transcribed from DNA, processed by removal of introns and addition of the cap structure and the poly(A) tail. The mature mRNA is then exported to the cytoplasm where it is translated into protein and finally degraded. In this process, mRNA is associated with RNA-binding proteins forming ribonucleoprotein complexes, whose protein content evolves throughout the lifetime of the mRNA. While the complexity of eukaryotic gene expression allows the production of proteins to be controlled at many levels, it also makes the process vulnerable to errors. Although eukaryotic cells have evolved elaborate mRNA quality control mechanisms that ensure the fidelity of gene expression, some defects are not detected, thus affecting mRNA metabolism. This condition plays a fundamental role in the pathogenesis of several disease processes, such as neurodegeneration and oncogenesis. Besides, exciting recent data have shown that cellular RNAs can be modified post-transcriptionally via dynamic and reversible chemical modifications, the so-called epitranscriptome. These modifications can alter mRNA structure, being able to modulate different steps of the mRNA metabolism that can be associated with various human diseases, such as systemic lupus erythematosus and cancer. This book provides a collection of novel studies and hypotheses aimed to define the pathophysiological consequences of altered mRNA metabolism events in human cells, and is written for a wide spectrum of readers in the field of gene expression regulation. The last chapter highlights how the discovery of disease-causing defects (or modifications) in mRNA can provide a variety of therapeutic targets that can be used for the development of new RNA-based therapeutics. Hopefully, it may also contribute to inspire the drug-developing scientific community.

mRNA Vaccines (Current Topics in Microbiology and Immunology #440)

by Dong Yu Benjamin Petsch

The formulation and the technological advancements in RNA biology, chemistry, stability, and encapsulated delivery systems that have enabled the development of fully synthetic mRNA vaccines are discussed in this volume. The applications of the mRNA technology is covered, focusing on infectious diseases but also touching on other indications, such as immunotherapies and molecular therapies. Potent and long-lasting immune responses observed in animal models, encouraging data from early human clinical studies, together with the success of two mRNA-based COVID-19 vaccines support the use of mRNA-based vaccination as an attractive alternative to conventional vaccine approaches. Consequently, the development progress of the technology, particularly on production, capabilities, and clinical development is reviewed. Topics on safety, regulatory issues, and possible challenges to the mRNA vaccination approach round off this book. Thanks to their high potency, the prospect for generic, low-cost manufacturing processes, and entirely synthetic nature, the future for mRNA vaccines is highly promising. Importantly, mRNA vaccines have the potential to minimize the time between pathogen identification and vaccine release with a huge impact on public health. As the mRNA-based vaccination technology has been progressing rapidly, the book is intended to be an end-to-end review series, covering everything from basic RNA biology and preclinical studies to the manufacturing strategy, clinical development and regulatory approval. It provides established RNA researchers and developers with updates on the latest advancements in the field and allows for a quick but comprehensive overview of this transformative technology, its application, and future potential.
