Brain tumor pathology : Current diagnostic hotspots and pitfalls

Since Bailey and Cushing (1926), all brain tumor classifications have been called histogenetic. The nosographic position that the tumor types progressively acquired in the classification systems derived from the resemblance of tumor cells to those of the cytogenesis, modified whenever new information became available from different biological research fields and especially from molecular genetics. Classically, on the basis of the rough correspondence between the mature/immature aspect of tumor cells and the benign/malignant biological behavior of the tumors, the histological labels contained a prognostic significance. The supposed origin of the tumors was thus a factor for prognosis. Later on, with the concept of anaplasia (Cox, 1933; Kernohan et al., 1949) new criteria were introduced for establishing the malignancy grades of tumors. Immunohistochemistry and later molecular genetics further refined the prognostic diagnoses, substantially increasing the opportunities to recognize the cell origin of tumors, beside revealing the pathogenetic mechanisms. Prognoses became more accurate, as required by the greater and more targeted possibilities of therapy.

Bone Morphogenetic Proteins : From Local to Systemic Therapeutics

Tissue engineering is gaining interest as it is applied for regeneration of organs to attain their lost function. Although resorbable scaffolds and progenitor cell types are required principles to engineer a functional tissue locally, the inductive signal is a prerequisite to trigger the growth and differentiation of responding cells in space and time. Bone morphogenetic proteins (BMPs), also called growth and differentiation factors (GDFs), originally identified from bone have been successfully used to regenerate the bone in humans. Most recent preclinical data suggests that BMPs have a potential to provide protection against inflammation and fibrosis in acute and chronic injury of parenchymal tissues when applied systemically to sustain the function of kidney and liver. The application of BMPs from a local to systemic utility is a rapidly growing field, gaining interest among researchers and biotech entrepreneurs.

Bone augmentation in implant dentistry : A step-by-step guide to predictable alveolar ridge and sinus grafting

Implant dentistry has evolved tremendously over the past three decades and is rapidly progressing as new materials and protocols become available each year. With the number of advancements made in digitally based media and marketing, it is imperative that the clinician is able to separate new trends from evidence-based protocols to make sound and predictable choices for the ultimate benefit of patients. This textbook presents cases from the author's 35-year practice to show the successes and failures of various treatment approaches and protocols. Early chapters discuss the relevant biomaterials and instruments utilized for bone augmentation protocols, including barrier membranes, bone grafting materials, and growth factors. Surgical chapters dedicated to extraction socket management, alveolar ridge augmentation, and sinus grafting follow, each chapter detailing specific indications and patient selection criteria as well as step-by-step surgical procedures, aspects of postoperative treatment, and complications. The final chapter focuses on full-arch reconstruction using fully guided immediate reconstruction protocols. The author's teaching institute is credited with preparing some of the world's best clinicians, and this book will pave the way for countless more.

Bipolar disorder

Mood" is defined as a ubiquitous and sustained feeling or emotion that dominates a person’s behavior and affects his perception. Mood disorders also known as affective disorders include unipolar and bipolar disorders. Manic-depressive disorder--more contemporarily identified as bipolar disorder (BD)--is a chronic and complex disorder of mood that is characterized by a combination of manic, hypomanic, and depressive episodes, with subsyndromal symptoms extant in between the mood episodes. It is one of the leading causes of worldwide disability and morbidity.

Biotechnology for the Future

One area that has attracted much attention is the use of cell factories for the production of a wide range of chemicals. This area illustrates very well the definition of biochemical engineering , and it has therefore been chosen as the focus of this volume. The use of cell factories for production of chemicals dates back to the production of penicillin, ethanol, acetone–butanol, glycerol and further to enzymes and other antibiotics. All these products were traditionally produced by cell factories that naturally produce these compounds. With the introduction of genetic engineering it has,This volume therefore contains chapters on concepts of metabolic engineering on detailed modeling of cellular systems

Biological processes associated with impact events

The biological effects of asteroid and comet impacts have been widely viewed as primarily destructive. The role of an impactor in the K/T boundary extinctions has had a particularly important influence on thinking concerning the role of impacts in ecological and biological changes. th During the 10 and final workshop of the ESF IMPACT program during March 2003, we sought to investigate the wider aspects of the involvement of impact events in biological processes, including the beneficial role of these events from the prebiotic through to the ecosystem level. The ESF IMPACT programme (1998-2003) was an interdisciplinary effort that is aimed at understanding impact processes and their effects on the Earth environment, including environmental, geological and biological changes.

Biological Invasions in New Zealand

Man’s recent colonization of New Zealand has dramatically altered the resident biota and resulted in the introduction of numerous alien organisms to these once remote islands. In reverse, there is increasing evidence of a lesser known export of species to other regions of the world. This volume presents an in-depth review of the level and rate of such invasions, and investigates what controls the success of invaders and the consequences for ecosystems both on land and offshore. It provides invasion biologists everywhere with tests of current theories about those factors leading to the success of invaders as well as evaluating principles for understanding the nature of their impacts that form a solid basis for the effective management of biological invasions worldwide.

Biogeography, Time, and Place : Distributions, Barriers, and Islands

Biogeography considers the distribution of biological units over a wide range of scales. The units range from genotypes, populations and species to families and higher taxa. Processes can be local, such as the isolation on islands due to sea-level fluctuations, or large-scale tectonic processes that separates continents and creates oceans. In all processes time is an important factor and by combining data on recent patterns with paleontological data the understanding of the distribution of extant taxa can be improved. This volume focuses on speciation due to isolation in island-like settings, and the evolution of large-scale diversity as the result of origination, maintenance and extinction.
