Glasses containing metallic nanoparticles exhibit very promising linear and nonlinear optical properties, mainly due to the surface plasmon resonances (SPRs) of the nanoparticles. The spectral position in the visible and near-infrared range and polarization dependence of the SPR are characteristically determined by the nanoparticles’ shapes. The focus of Ultra-Short Pulsed Laser Engineered Metal-Glass Nanocomposites is the interaction of intense ultra-short laser pulses with glass containing silver nanoparticles embedded in soda-lime glass, and nanostructural modifications in metal-glass nanocomposites induced by such laser pulses. In order to provide a comprehensive physical picture of the processes leading to laser-induced persistent shape transformation of the nanoparticles, series of experimental results investigating the dependences of laser assisted shape modifications of nanoparticles with laser pulse intensity, excitation wavelength, temperature are considered. In addition, the resulting local optical dichroism allows producing very flexibly polarizing optical (sub-) microstructures with well-specified optical properties. The achieved considerable progress towards technological application of this technique, in particular also for long-term optical data storage, is also discussed.

The second edition of this book is more extensive and detailed than the previous edition published 20 years ago. New technical methods have increased our understanding of many tumours. The earlier group of monomorphic adenomas has been separated out for purposes of identification, and clearly defined tumours, even if uncommon, are categorized separately. Because of their different pathohistological definitions and differences in prognosis and treatment, a separate listing of the various types of carcinomas was preferred, and new entities are included (for example, polymorphous low-grade adenocarcinoma and basal cell adenocarcinomas). TNM classification of salivary gland tumours has been included along with a more detailed description of tumour-like lesions in the salivary gland. This reference book on pathology, oncology and otorhinolaryngology is intended for clinicians and researchers.

Das Werk behandelt in 18 Kapiteln den gesamten aktuellen Wissensstand der Pathologie der Mundhöhle mit angrenzendem Weichteil- und Knochengewebe unter Berücksichtigung der umfangreichen Literatur. Die zahlreichen Abbildungen und Tabellen sollen sowohl dem interessierten Kliniker wie auch dem Pathologen den weiteren Zugang zu den vielfältigen Krankheiten der Mundhöhle ermöglichen. Der Band wendet sich daher besonders an die Fachdiziplinen der Zahnmedizin, Mund-, Kiefer- und Gesichtschirurgie, Hals-, Nasen-, Ohrenheilkunde sowie an die Dermatologie und Innere Medizin.

Die Speicheldrüsen sind in mannigfacher Weise in den Organismus eingebunden, so daß aus der Analyse des Speichels Rückschlüsse auf krankhafte Funktionen anderen Organsysteme gezogen werden können.

New methods in immunocytochemistry and hybridization techniques enable the pathologist active in diagnosis to clarify more effectively problems in the classification and prognosis of tumors. By adopting these methods into his diagnostic repertoire it will be possible to create a closer, more productive connection between morphological diagnosis and clinical work. This volume gives the reader an up-to-date general survey from international experts of the method, technique and practical application of these new procedures.

An up-to-date review of the morphology and pathological aspects of cell receptors, important because new therapies for various pathological conditions (genetic diseases, endocrine disorders, cancer, etc.) could be based on receptor interference.

Oral Pathology as part of the Head and Neck Pathology is an interdisciplinary field of science. The oral mucosa and the saliva are reflectors of many systemic diseases of the organism and therefore valuable parameters of the diagnosis and prognosis of pathological processes. In the last years many new methods have been integrated in the diagnostic repertoire. Proliferation markers are of predicitive value and characterize the biological behavior of a tumor. Markers are such as oncogenes, growth factor receptors or genetic aberrations. The importance of these new markers shall be discussed concerning the different types of oral cancers and salivary gland tumours.
