Biology

For one or two semester courses in Introductory Biology targeting non- and mixed majors. The goal of this text is to provide an engaging and easy to use book with an innovative and interactive media program. It achieves a unique balance in emphasizing concepts without sacrificing scientific accuracy. The new MediaTutor, found at the end of each chapter, integrates the text and media by providing a brief description of the CD or WEB activity and the time requirement for completion. In creating the book and the media package, the authors and Prentice Hall reached out to the biology community - involving educators from around the country to help address the diverse needs of todays students. How do you engage your students and help make biology relevant to them? *NEW - Chapter-opening Case Studies and chapter-ending Case Studies Revisited - Includes Did Dinosaurs Die from Lack of Sunlight? from the chapter on Photosynthesis and Teaching an Old Grain New Tricks from the chapter on Biotechnology. Provides an innovative framework for students to learn and make connections between biological concepts and processes. *Earth Watch/Health Watch essays - Covers biodiversity, ozone depletion/pre

Development of Plant-Based Medicines: Conservation, Efficacy and Safety

The `plant' is often the most neglected part of plant-based medicine. Throughout time, humans have searched, collected, and effectively used plants for healing. Currently, the medicinal plant-based business is flourishing at a dramatic pace and at the expense of an already declining population of plant species, many of which are on the verge of extinction. In spite of this history and popularity, the mystery of what transforms a plant into a medicinal plant persists, and there are chronic problems with ensuring the safety and efficacy of medicinal plant products. Therefore, there is a real need for a full characterization of medicinal plant species and for the development and application of novel technologies for the production of plant-based medicines. This book highlights some of the recent advances and new approaches to the development of technologies for plant-based medicines and is intended to stimulate new discussions among researchers, regulatory authorities, and pharmaceutical organizations, leading to significant advancements in the field.
