Several papers dealing with the clinical relevance of steroid hormone receptors in breast cancer have already been published. However, no publication has overviewed studies currently being conducted in Europe, nor is there a register of the european centers performing receptor assays. It has been our purpose to fill these gaps. A large majority of authors who we contacted kindly agreed to con tribute to our book. Papers were grouped into six main parts according to their contents. The abundance of clinical data relevant to receptor assays led us to add critical summaries to help the reader to form his own opinions on the subject. We would like to thank Drs. R. J. B. King, G. Contesso, L. Santi, and E. Engelsman, who helped us in this regard. We hope that this book will enable the reader to become acquainted with the present state of European steroid hormone receptor studies devoted to breast cancer treatment. We also hope that it will promote cooperation between European oncologists involved in this field of research."

Heterogeneous catalysis plays a central role in the global energy paradigm, with practically all energy-related process relying on a catalyst at a certain point. The application of heterogeneous catalysts will be of paramount importance to achieve the transition towards low carbon and sustainable societies. This book provides an overview of the design, limitations and challenges of heterogeneous catalysts for energy applications. In an attempt to cover a broad spectrum of scenarios, the book considers traditional processes linked to fossil fuels such as reforming and hydrocracking, as well as catalysis for sustainable energy applications such as hydrogen production, photocatalysis, biomass upgrading and conversion of CO2 to clean fuels. Novel approaches in catalysts design are covered, including microchannel reactors and structured catalysts, catalytic membranes and ionic liquids. With contributions from leaders in the field, Heterogeneous Catalysis for Energy Applications will be an essential toolkit for chemists, physicists, chemical engineers and industrials working on energy.

The blood-brain barrier (BBB) is a membranic structure that acts primarily to protect the brain from chemicals in the blood, while still allowing essential metabolic function. It is composed of endothelial cells, which are packed very tightly in brain capillaries. This higher density restricts passage of substances from the bloodstream much more than endothelial cells in capillaries elsewhere in the body. Astrocyte cell projections called astrocytic feet (also known as "glia limitans") surround the endothelial cells of the BBB, providing biochemical support to those cells. The BBB is distinct from the similar blood-cerebrospinal fluid barrier, a function of the choroidal cells of the choroid plexus, and from the Blood-retinal barrier, which can be considered a part of the whole (the retina of the eye is an extension to the central nervous system and as such, can be considered part of the BBB).
