You are at a dinner with someone attractive. She suddenly kisses you. Or he leans unexpectedly across the table and caresses your thigh. Whatever. You know the kind of encounter and the range of possible responses. Consider the kiss. What does it mean, and where does it lead? Does kissing necessarily imply more, and if so how much? These and similar questions of amorous ethics and erotic disquisition are the central to our everyday intimate public lives and they are the lost object of the law of love, the "lex amatoria" collated and presented here.

Flavins and flavoproteins are a widely investigated and highly versatile group of compounds. Participation of these compounds in photochemistry and photobiology processes are of particular importance in the fields of biology, chemistry and medicine. Written by leading experts in the field each section of the book includes a historical overview of the subject, state of the art developments and future perspectives. Flavins: Photochemistry and Photobiology begins with the properties and applications of flavins, including their photochemistry in aqueous and organic solutions. Subsequent sections discuss riboflavin as a visible light sensitizer in the photo degradation of drugs, antiviral and antibacterial effects, the role of flavins in light induced toxicity and blue light initiated DNA repair by photolyase. Finally there are sections on the flavin based photoreceptors in plants, bacteria and eukaryotic photosynthetic flagelettes. This book brings together leading experts with a unique interdisciplinary emphasis, to provide an authoritative resource on flavins and their role in photochemistry and photobiology.
