MRI Contrast Agents
This book describes the multiple aspects of (i) preparation of the magnetic core, (ii) the stabilization with different coatings, (iii) the physico-chemical characterization and (iv) the vectorization to obtain specific nanosystems. Several bio-applications are also presented in this book. In the early days of Magnetic Resonance Imaging (MRI), paramagnetic ions were proposed as contrast agents to enhance the diagnostic quality of MR images. Since then, academic and industrial efforts have been devoted to the development of new and more efficient molecular, supramolecular and nanoparticular systems. Old concepts and theories, like paramagnetic relaxation, were revisited and exploited, leading to new scientific tracks. With their high relaxivity payload, the superparamagnetic nanoparticles are very appealing in the context of molecular imaging but challenges are still numerous: absence of toxicity, specificity, ability to cross the biological barriers, etc.

Trends in Contrast Media
A different approach to contrast media, discussed primarily from the point of view of the radiologist. Comprehensive sections are devoted to iodinated contrast media and to the contrast media employed in magnetic resonance imaging and ultrasonography. The latest agents available receive due attention, as do adverse reactions. A final section considers the use of contrast media in nuclear medicine.
Trees of Santa Barbara
This volume is a complete revision of the Santa Barbara Botanic Garden's Trees of Santa Barbara, last published in 1974. Detailed descriptions of each species are provided and supported by over 800 photographs of overall habit, flowers, fruit, and leaves. Viewing locations are noted, and anecdotal observations serve to bring each species to life. While the focus is on the trees of Santa Barbara, most of the species described here can be found in horticultural settings extending from San Francisco to San Diego.
