Sommario/riassunto

As we move toward the year 2000, Americans continue to debate the job of First Lady. How much power does the position actually hold? How publicly should that power be wielded? First Ladies tells the story of this curious institution and the evolution of these women's role from ceremonial backdrop to substantive world figure. This expanded edition brings us up to the present, examining the legacies of our three most recent First Ladies: Nancy Reagan, credited with raising the job to that of ""Associate President""; Barbara Bush, who took a more



traditional approach); and Hillary Rodham Clinton,

Sommario/riassunto

This first systematic summary of the impact of fragment-based approaches on the drug development process provides essential information that was previously unavailable. Adopting a practice-oriented approach, this represents a book by professionals for professionals, tailor-made for drug developers in the pharma and biotech sector who need to keep up-to-date on the latest technologies and strategies in pharmaceutical ligand design. The book is clearly divided into three sections on ligand design, spectroscopic techniques, and screening and drug discovery, backed by numerous case studies.
