There's a silent epidemic in western civilization, and it is right under our noses. Our jaws are getting smaller and our teeth crooked and crowded, creating not only aesthetic challenges but also difficulties with breathing. Modern orthodontics has persuaded us that braces and oral devices can correct these problems. While teeth can certainly be straightened, what about the underlying causes of this rapid shift in oral evolution and the health risks posed by obstructed airways? Sandra Kahn and Paul R. Ehrlich, a pioneering orthodontist and a world-renowned evolutionist, respectively, present the biological, dietary, and cultural changes that have driven us toward this major health challenge. They propose simple adjustments that can alleviate this developing crisis, as well as a major alternative to orthodontics that promises more significant long-term relief. Jaws will change your life. Every parent should read this book.

The task of updating the classification was given to the Classification and Nomenclature Committee of the International Society of Gynecological Pathologists and its four subcommittees. This classification reflects the present state of knowledge and modifications are almost certain to be needed as experience accumulates. Since many of the tumours and tumour-like conditions in the classification occur in several sites in the female genital tract, cross-referencing from one site to another has been done in illustrating these lesions.

Seeking Symmetry: Finding patterns in human health offers a guide through the overwhelming mass of data generated by contemporary science. Starved for the knowledge that would best help us stay healthy, we are simultaneously glutted with an overload of information about the human body. Amidst ubiquitous talk that patient-centred care and lifestyle changes are the keys to personal health, self-neglect and medical overtreatment nevertheless prevail. The body is rich with symmetries, many of them unknown to us who live in these bodies. Symmetry-seeking reveals certain patterns for understanding the information we have about the body, patterns whose roots lie in embryonic development and in evolution. The book's exploration will guide readers through the parts of their own bodies and introduce tangible, visible examples of symmetry, not only right and left but up and down, male and female, inside and out, as well as symmetries between humans and other species.It presents the symmetries of the body's internal structures that, despite their complexity, are nevertheless simple to understand when viewed with an eye for pattern.Through both words and images, this book will illustrate the most foundational of the principles, structures, and processes that decide how bodies function.A core purpose of the book is to present this knowledge through a lens that makes the information meaningful, by modelling the habit of symmetry-seeking.

During the two decades since the publication of the first edition of Histological Typing of Bone Tumours, new methods of diagnosis, es- pecially radiological imaging techniques (computed tomography and magnetic resonance imaging), associated with advances in the new cytomorphological methods including immunohistochemistry, DNA ploidy analysis, cytogenetic chromosomal investigation, etc., have greatly improved our diagnostic tools and treatment results. These advances are reflected by the publication of new editions of various important textbooks in recent years. In these publications classifica- tion criteria differed. In contrast, the WHO classification has been relatively unaltered, and has introduced a limited number of new entities and subdivided others because of distinct histological features and biological be- haviour. In general the framework and the concept of the original classifi- cation, as it has been widely accepted, remains essentially unchanged. The classification is based on the line of histological differentiation, in many instances reflecting the type of intercellular matrix material produced. This approach is justified because it avoids theoretical his- togenetic controversies.

Although more than 12 years have passed since publication of the first WHO histological classification of central nervous system (CNS) tumours, the changes in this revised edition are not radical. Only one formerly recognized entity has been deleted: the monstrocellular sarcoma, because there is immuno- cytochemical evidence of its astrocytic nature. Several new tumour types have been added: the pleomorphic xanthoastro- cytoma has been generally acknowledged for almost a decade; the neurocytoma has gradually evolved as a clinical-pathological entity; and two new entries, the dysembryoplastic neuroepi- thelial tumour and the desmoplastic infantile ganglioglioma, have only been characterized morphologically during the past few years. We regard the classification as an international standard to facilitate communication and have tried to avoid current con- ceptual controversies. The majority of partiCipants supported inclusion of the term "primitive neuroectodermal tumour" (pNET). However, because of our limited knowledge of the biol- ogy of embryonal CNS tumours, preference was given to use PNET selectively, rather than applying it to all small cell embryo- nal childhood tumours, irrespective of their histological pheno- type. Ependymomas and meningiomas now have new histological SUbtypes. Most of these are not associated with biological behaviour different from the parent tumour type, but their description will aid the practising pathologist to identify and classify these lesions. 2 Introduction Histological Typing Following the philosophy of this WHO series, classification is based primarily on histological assessment of cell types and tis- sue patterns recognized by conventional light microscopy.

International experts review the molecular biology of ion channels, diseases of the central nervous system including Alzheimer's disease, the molecular biology of atherogenesis, plasma lipproteins, lipid transport, long chain fatty acid transport and metabolism, and lipoprotein receptors. Future directions and perspectives and common features in these important areas are discussed.

Knowledge of tumours of the thyroid gland has advanced consider- ably in the 22 years that have elapsed since work was started on the first edition of Histological Typing of Thyroid Tumours. In the intro- duction to that volume it was recognized that the definitions and clas- sifications put forward would need revision in time, and the present text differs substantially from the first edition. As far as is possible, however, the framework of the classification proposed remains the same, as the original classification was widely accepted and proved useful in many studies. The link between the morphological type of thyroid tumour and its epidemiology, natural history, function, prognosis and response to therapy has been further strengthened since the first edition. In par- ticular, the decision taken to separate papillary and follicular carcino- mas and exclude a mixed papillary follicular type has been well justi- fied. One of the major changes has been the recognition that many tu- mours regarded 20 years ago as small cell carcinoma were really ma- lignant lymphoma, and this development has been incorporated into this edition, with increased importance given to primary malignant lymphoma of the thyroid. Much work has also been done on medul- lary carcinoma of the thyroid, its link with mUltiple endocrine neo- plasia syndromes, and its association in its inherited form with C-cell hyperplasia; this too is recognized by an expanded section on this tu- mour.

A new approach using comparative neuromorphology is taken in this study dealing with the organization of the efferent nuclei of cranial nerves. The authors use the cobalt labelling technique to identify neuron types and follow their presence, or absence, in different animal species. They suggest a new classification which is free from a number of controversies inherent in the classical classification. The results suggest that evolutionary changes in the center and in the innervated periphary parallel each other with increasingly complex function.

Anatomy of Movement presents a dynamic, integrated approach to the study of the physical structures of the musculoskeletal system and their functional relationship to the movements of the human body. In clear and concise text illustrated with more than a thousand graphic drawings, the author guides the reader on a lively tour of the muscles, bones, ligaments and joints of the arms, legs and trunk. The focus throughout the book is on anatomy not for its own sake, but in its functional relationship to the actual movements of the body in dance, exercise, and other physical disciplines. In this newly-revised edition, a majority of the thousand-plus illustrations are new or have been modified by the author from the original edition. The text has also been updated, and the sequencing of the presentation of the musculoskeletal anatomy has been revised in part.

1. 1 The Cytokeratins as a Member of the Intermediate Filament Protein Family Intermediate filaments together with microtubules and actin microfilaments make up the filamentous cytoskeleton found in the cytoplasm of vertebrate cells. Recently, intermediate filament proteins have also been described in invertebrates, but their chemistry is not yet known (for review see Biessmann and Walter 1989). These filaments (about 10 nm in diameter) used to be categorized into five classes - cytokeratin, vimentin, desmin, glial fibrillary acidic protein (GFAP), and neurofilaments (NFs). The expression of these proteins follows differentiation-dependent rules: cytokeratins occur in epi- thelial cells, NF proteins are expressed in neurons, GFAP in astrocytes and some nonglial cells, desmin in smooth muscle cells and in striated myocytes, and vimentin in mesenchymal cells (for review see Lazarides 1980; Osborn and Weber 1983). Recent investigations including deoxyribonucleic acid (DNA) and protein sequencing and peptide mapping have redefined the intermediate filaments into five types or subfamilies (type I, acidic cytokeratins; type II, basic cytokeratins; type III, vimentin, desmin, peripherin, and GFAP; type IV, the three NF proteins; and type V, the nuclear lamins (for review see Nagle 1988). A new type VI intermediate filament protein, nestin, has been described in the developing nervous system (Lendahl et al. 1990), and is initially co- expressed with vimentin in neuroepithelial stem cells (Steinert and Liem 1990). The cytokeratins are the most complex subgroup of intermediate filament proteins.

The international symposium on transposition of the great arteries was held in Munich on May 3-5, 1991. It was organized by the German Heart Center Muni eh with two aims: firstly, to commemorate the 25th anniversary of Dr. Rashkind's publication: "Creation of an atrial septal defect without thoracotomy" (which appeared in 1966 in the Journal of the American Medical Association), and to honor this great pediatric cardiologist, who was one the pioneers of interventional catheterization. secondly, to give an overview of current medical knowledge about the pre- and postnatal diagnosis, medical and surgical treatment, and postoperative evalua- tion of transposition of the great arteries. Fig. 1. Dr. Rashkind in his Iabaratory checking his balloon catheter V This symposium brought tagether embryologists, morphologists, experts in fetal cardiology, pediatric cardiologists, and pediatric cardiac surgeons from 10 different countries. Thus, we were able to describe the current state-of-the-art of pre- and postnatal management and the surgical treatment of this second most common con- genital cyanotic anomaly of the heart. Dr. Rashkind's approach to create an atrial septal defect in the setting of com- plete transposition of the great arteries dramatically changed the natural history of this cyanotic heart defect, which carried a 90% neonatal mortality before this effec- tive palliation became available.

This is not a textbook. Instead, it contains what the author judges necessary to cope with questions relating to Gross Anatomy in board and licensure exami nations. Although material that has appeared recently on (Part I) National Board Examinations is covered, simply listing and answering such questions certainly would not prepare you for the myriad possible alternatives. Because of your suc cessful background in anatomy, the approaches used in a first-year course are not necessary here. Recall, review and synthesis are the goals. Please examine the entire book now, to understand its organization and content, and how they may serve your needs. Throughout, text is kept to a minimum. The style, size and boldness of type were chosen to aid the quick recognition of import items. The illustrations, es sentially adaptations from blackboard drawings used by the author in reviews, support the text in certain areas. However, the number of illustrations sufficient to make this an independent resource would defeat our purpose. I assume you will consult your favorite atlas as you review, and that you are experienced enough now to relate your reading to your own body. A general table of contents follows this preface; detailed tables of content precede individual chapters."

Three additional sections have been added in this edition in response to stu dents' suggestions. A short summary of motor deficits, a brief discussion of cra nial nerve functions and some examples of localizing signs of anatomic lesions should prove helpful in applying basic principles to clinical situations. P.A. Roberts Preface The following notes, originally known as Neuroanatomical Notations, were pre pared for the purpose of providing a quick review of some of the pertinent points that should be considered in refreshing your memory of Neuroanatomy. Obviously the booklet is not encyclopedic, and is certainly not intended as a text on the subject. However, hopefully, it will serve as a useful guide and be of aid in the task of systematically preparing for Part I of the National Boards and similar examinations. P.A. Roberts "I can't believe that " said Alice. "Can't you " The Queen said in a pitying tone. "Try again: Draw a long breath, and shut your eyes." Alice laughed, "There's no use trying," she said. "One can't believe impossible things." "I dare say you haven't had much practice," said the Queen."

1. 1 Historical Perspective In the nineteenth century, knowledge of the events leading to ovulation, fertilization, and implantation was very limited, so much so that Seiler (1832), in his book The Uterus and the Human Egg, wrote: ." . . in the left ovary the first signs of fertilization, namely a Graaf vesicle could be seen. The right ovary shows proof of a second successful copulation: a fresh scar from the ovulated egg and the beginning of a corpus luteum. " In fact all nineteenth century authors strictly divide the female cycle into two phases: the menstrual period and the intermenstruum (ct. Hitschmann and Adler 1908). The generally accepted histology of the endometrium in those days was that of the late proliferative phase. Deviations from this were considered to be pathological (Von Ebner 1902). As Gebhard (1899) expressly put it: "As a rule, it can be said that in the mature woman the endometrial glands run straight; an irregular course of the glands is to be regarded as pathological. " The same author describes the changes occurring during the secretory phase of the cycle as "endometritis glandularis" which he believed to arise from a local nutritional disturbance. The uterine stroma was believed to be lymphoid (Toldt 1877), and the uterine glands were compared to the crypts of Lieberkiihn (Von Ebner 1902).

This second edition is more extensive and detailed than the previous one - now a reference of two decades standing. New technical methods have increased our understanding of many tumours, and the earlier group of monomorphic adenomas has been separated for easier identification, while clearly defined tumours - even if uncommon - have their own category. With reference to their differences in prognosis and treatment, the various types of carcinomas are now listed separately, and new entities have been adopted. The inclusion of the TNM classification of salivary gland tumours together with the more detailed description of the tumour-like lesions will contribute to an even better understanding.

In the present work, processes of cell proliferation, cell death, neurogenesis, and gliogenesis in the mouse hippocampus were studied. The mapping of distribution of hippocampal mitoses and counting of their number allowed a more precise definition of the data concerning the disposition and age reduction of proliferative sites in Ammon's horn and the dentate gyrus in the mouse. As a result, the following generalized scheme of development and age reduction of the germinal zones in the mouse hippocampus has been suggested. 1. Ammon's horn a) The ventricular zone, from the beginning of formation of the hippocampus (Ell) until E20 b) The suprafimbrial zone, from El6 until P7 2. Dentate gyrus a) The prime germinal zone ("the anlage of the dentate gyrus" of Stanfield and CowanI979b), from E15 until P3 b) The proliferative zone of the hilus, from P3 until Pl4 c) The subgranular zone, from P3 until adult age The adduced scheme needs some comments: 1. In the hippocampus (as well as in other formations of the developing brain), primary precursors of all types of cells of neuroectodermal origin are represented by cells of the ventricular zone. They give rise to cells of secondary germinal zones in the dentate gyrus and Ammon's horn and are direct precursors of the majority (if not of all) neuronal cells in Ammon's horn, the earliest originating generations of neurons in the dentate gyrus, hippocampal radial glial cells, and, evidently, of a considerable part of astroblasts and oligodendroblasts in Ammon's horn.

This book is intended for students of medicine, pharmacy and other biological disciplines, who want to have a working knowledge of the mechanisms of action, uses and adverse effects of drugs which modify the activity of neurotransmitters in the peripheral and central nervous systems. It is suitable for undergraduates and for post-graduates on taught higher degree courses and diplomas. New information and concepts have been incorporated into the text as appropriate, and references have been updated. Excitatoryand inhibitory amino acids are considered in two chapters, and the last chapter of the first two editions (which considered drugs which do not interact selectively with neurotransmitters) has been subsumed into other sections. The third edition follows the tried format of previous editions. Following a chapter which introduces the biology and pharmacology of neurotransmission, subsequent chapters deal with synthesis, storage, release, receptors and inactivation of individual neurotransmitters, together with a consideration of therapeutic uses and mechanisms of adverse effects.

Retaining the same scope as the first edition, this new edition deals with the classification and characteristics of tumours and tumour-like lesions. Similar information is also given on odontogenic and non-odontogenic cysts of the jaws. It is extensively illustrated with photomicrographs in colour, together with clinical radiographs and photographs of operation specimens to show the distinctive features of various lesions. The classification has been updated to reflect the present state of knowledge and changes in views, and includes a number of newly recognised entities.

Strongly recommended for the surgical trainee this, the second of a number of atlas-texts describing the anatomical basis of a range of common surgicalprocedures, is a useful aide-memoir to operative surgery

Disturbances in peripheral O extraction can be produced in dogs treated with 2 endotoxin and thereby provide an opportunity to test theories for the origin of pathological O supply dependency or to try different treatment modalities. The 2 most serious deficiency in the current animal models is the inability to mimic the increased O demand that is observed in patients at 02 delivery rates in excess of 2 normal. A particular feature of this increased O demand is that it apparently does 2 not stimulate increased 02 extraction, although the limitation in O extraction has 2 not been explored in patients by lowering 02 supply, for obvious reasons. At least two possibilities to account for increased 02 demand could be investigated in animal models, however. The amount of 02 that is utilized in extramitochondrial pathways, which is normally on the order of 10%, may be greatly increased in ARDS and sepsis by O radical formation. There is presently no information 2 concerning how much 02 might be used in this way. Another strong possibility is that mitochondrial injury, perhaps as a result of 02 radical formation, uncouples oxidative phosphorylation. Some evidence presently in the literature supports this idea [19]. Indeed, the association of increased blood lactate levels with higher than expected 02 demands makes uncoupling a very attractive hypothesis that warrants further investigation in animal models using such agents as 2,4-dinitrophenol.
