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.

Brain Metastases

Brain metastases are the most dreaded complication of systemic cancer, affecting approximately 170,000 people a year, a far greater incidence than primary brain tumors. Advances in modern chemotherapy have led to an improved control of system cancers, often with agents that poorly penetrate the central nervous system, resulting in an increasing incidence of brain metastases. Traditional chemotherapy has had little impact on brain metastases. The main therapeutic option is radiation therapy, and in a small number of patients - surgery. However, refinements in all of these treatments offer some positive outcomes and an increased ability to stratify patients based on certain criteria.

Biological Invasions Belowground : Earthworms as Invasive Species

he most conspicuous biological invasions in terrestrial ecosystems have been by exotic plants, insects and vertebrates. Less conspicuous but possibly of equal importance are invasions by soil invertebrates, which are occurring literally beneath our feet. Familiar examples include the South American fire ant (Solenopsis invicta) which has invaded North America and Australia, and the New Zealand flatworm (Arthurdendyus triangulatus) which has become wide-spread in the United Kingdom; both have caused considerable ecological and economic damage. There is now evidence that exotic earthworm invasions are increasing world-wide and may be having significant impacts on soil processes and plant communities in some regions. Much remains to be learned about these ‘cryptic’ biological invasions. The papers in this book are based on efforts by an international group of soil ecologists to assess the biological and ecological mechanisms of earthworm invasions, their geographic extent and impacts on terrestrial ecosystems, and possible means by which earthworm invasions might be mitigated.

Beyond Cartesian Dualism : Encountering affect in the teaching and learning of science.

There is surprisingly little known about affect in science education. Despite periodic forays into monitoring students’ attitudes-toward-science, the effect of affect is too often overlooked. Beyond Cartesian Dualism gathers together contemporary theorizing in this axiomatic area. In fourteen chapters, senior scholars of international standing use their knowledge of the literature and empirical data to model the relationship between cognition and affect in science education. Their revealing discussions are grounded in a broad range of educational contexts including school classrooms, universities, science centres, travelling exhibits and refugee camps, and explore an array of far reaching questions. What is known about science teachers’ and students’ emotions? How do emotions mediate and moderate instruction? How might science education promote psychological
