The first part of the book describes kinetic studies between a nucleophile and an electrophile when one or both of the reagents were incorporated into vesicles (liposomes) and compares reaction rates for the same reagents in a solution. Several modes of reactivity under comparable conditions have rates of decreasing magnitude according to intra-vesicular > solution/solution > solution/vesicle > inter-vesicular. Vesicle/vesicle reactivity models numerous cell/cell reactions found in biology. The second part of the book discusses a family of new asterisk-shaped amphiphiles, which were prepared and studied by means of tensiometry, calorimetry, dynamic light scattering, UV/Vis spectroscopy, fluorescent spectroscopy, conventional NMR spectroscopy and FT-PGSE NMR spectroscopy. These water-soluble asterisk-shaped amphiphiles belong to a fast-growing family of structurally novel amphiphiles, appearing on the scientific scene and expanding the scope of Colloid Chemistry. The book is aimed at a broad auditorium of scientists interested in Organic, Physical Organic, Supramolecular, and Colloid Chemistry.

Serosal Membranes (Pleura, Pericardium, Peritoneum): Normal Structure, Development and Experimental Pathology (Advances in Anatomy, Embryology and Cell Biology)
The coelomic cavities are covered with serosal membranes: peritoneum, pleura, pericardium and tunica vaginalis testis. The present review compiles data, on their normal structure, development and involvement in pathologic processes. The authors add also results on the ultrastructure of the parietal pleura, peritoneum and pericardium and visceral sheets of the different organs as well in transitional areas between them in man and experimental animals (rat, cat, rabbit, guinea pig, mouse, ground squirrel). By transmission and scanning electron microscopy they distinguish three basic types of relief on both serosal sheets, organs and their different regions. The authors provide a comprehensive description of the main components of the SM involving: mesothelium, an underlying basal lamina and submesothelial connective tissue layer.
