This book, now in its third, completely revised and updated edition, offers a critical approach to the challenging interpretation of the latest research data obtained using functional neuroimaging in whiplash injury. Such a comprehensive guide to recent and current international research in the field is more necessary than ever, given that the confusion regarding the condition and the medicolegal discussions surrounding it have increased further despite the publication of much literature on the subject. In recent decades especially the functional imaging methods – such as single-photon emission tomography, positron emission tomography, functional MRI, and hybrid techniques – have demonstrated a variety of significant brain alterations. Functional Neuroimaging in Whiplash Injury - New Approaches covers all aspects, including the imaging tools themselves and the various methods of image analysis. Details on biomechanics, including the finite element method and facts on historical whiplash experiments and crash tests have now been added to this new edition. The book will continue to help physicians, patients and their relatives and friends, and others to understand this condition as a disease.
If you want to buy a new car today, you can expect a flood of digital features and assistance systems that initially make the analog human heart beat faster. But are these developments right? Can we use all the built-in functions usefully and appropriately and operate them safely in increasingly hectic and dangerous everyday traffic?
Background/Objectives: The subject of this work is the reconstruction of the inner mechanics of Götz von Berlichingen's second "Iron Hand". The complex inner mechanics were unknown until Christian von Mechel published a detailed description in 1815. In this artificial hand, each finger can be engaged individually in its three joints and the thumb in one joint.
Methods: Based on this description, the individual components were reconstructed at an enlarged scale of 2:1 using CAD software and a 3D printer for the mechanisms. In addition, an FEM analysis was carried out for the components exposed to the greatest stress in order to identify critical areas.
Results: By making some adjustments to the mechanics, it was possible to reproduce the mechanisms on a scale of 2:1 on the basis of the index finger. However, if the model was scaled back to 1:1, the internal plastic components were too fragile. This problem was caused by the properties of the 3D printing materials and could be solved by manufacturing the springs from steel.
Conclusions: This work aims to make a valuable contribution to the preservation and understanding of the historical artificial second "Iron Hand" of Götz von Berlichingen. It once again demonstrates the very precise and detailed craftsmanship of goldsmiths of that time.
Cardiac resynchronisation therapy (CRT) is a promising treatment option in patients with chronic heart failure. In this article the roles of semi-invasive esophageal left-heart electrocardiography and functional cardiac nuclear imaging in the field of CRT are highlighted, as the combination of both could be a favourable diagnostic approach in special cardiac situations. Also original esophageal left heart electrogram data of exemplary CRT patients is presented.
Knight Götz von Berlichingen (1480–1562) was born into a time of upheaval during the transition from the late Middle Ages to modern times. Götz bravely defended the ideals of declining chivalry. He fought in numerous battles and engaged in several “feuds” with various other knights and even cities; during the Landshut War of Succession (1504/05), he lost his right hand in 1504 due to a cannonball splinter injury.
