The Alkaloids: Chemistry and Pharmacology
The Alkaloids: Chemistry and Pharmacology
Reason and Imagination
This book is about the recognition of new principles in Organic Chemistry. It is also about the discovery and invention of Chemical Reactions. In addition, it deals with the determination of structure by chemical degradation during the epoch when physical methods were not well developed. Also presented are new reagents and new types of functional groups never seen in chemistry before. The overall aim of the collected papers is to show how thought can direct original research and to demonstrate how thought about old or new chemical facts can lead to originality. This is further illuminated by commentaries which Prof Barton has written to accompany these papers.
Chemistry and Biology
Chemistry and Biology is a celebration of the outstanding contributions to the field by Professor R.H.F. Manske, who founded the series in 1950. This special volume demonstrates the dramatic changes in alkaloidchemistry since then. It also offers a unique overview of recent developments in major areas of alkaloid chemistry and biology and looks at how these areas will develop in the future. These fourteen contributions are written by many of the leading alkaloid chemists in the world, and thus comprise a unique view of alkaloids and their contributions to the health and well-being of humankind. Indispensable reference work written by leading experts in the field Provides up-to-date, timely reviews on compounds and classes of great interest Covers synthesis, biosynthesis, biology, as well as isolation and structure elucidation An essential research tool for anyone working with alkaloids from a chemical or biological perspective
Photochemical Synthesis
The Best Synthetic Methods Series is aimed at practising organic chemists who require up-to-date details of working methods for the synthesis of organic compounds. This volume concentrates on the synthesis of compounds with specifictypes of structures which has not been possible by standard thermal methods. For ease of use the photochemical reactions covered have been presented by their functional groups.
Minimally Invasive Neurosurgery
Recognized clinical leaders in neurosurgery and neuroradiology review the cutting-edge techniques and technologies now available and describe how minimally invasive techniques have influenced their subspecialties. On the radiology side, the authors explain the latest developments in magnetic resonance spectroscopy, functional imaging, and brain mapping, with emphasis on the application of image navigation directly in the operating room, using both preoperative and intraoperative systems. On the surgical side, some of the world's leading surgeons in pediatric neurosurgery, cerebrovascular surgery, neurosurgical oncology, spinal and peripheral nerve surgery, and trauma surgery detail how they use the powerful new minimally invasive techniques in the own practices. Among the novel approaches discussed are radiofrequency, radiosurgery, thermal therapy, and minimally invasive techniques that allow "molecular neurosurgery" via gene and viral vectors and local delivery systems.
Phytochemical Screening and Pharmacological Investigations on Hedychium Coronarium
The present study was carried out for phytochemical screening and pharmacological investigations on methanolic extract of rhizomes of Hedychium coronarium (Local name: Dolan Champa, Family: Zingiberaceae). In this study, the possible analgesic and CNS (Central Nervous System) depressant activities of the methanolic rhizome extract of Hedychium coronarium were investigated at the doses of 100 mg/Kg, 200 mg/kg and 400 mg/Kg body weight on mice by oral administration. The analgesic activities were investigated for their central and peripheral pharmacological actions using tail immersion testing and acetic acid-induced writhing testing respectively. Its CNS depressant activity was evaluated by using hole cross and open field tests and the cytotoxic activity was observed using brine shrimp lethality bioassay.

Photochemistry
The breadth of scientific and technological interests in the general topic of photochemistry is truly enormous and includes, for example, such diverse areas as microelectronics, atmospheric chemistry, organic synthesis, non-conventional photoimaging, photosynthesis, solar energy conversion, polymer technologies, and spectroscopy. This Specialist Periodical Report on Photochemistry aims to provide an annual review of photo-induced processes that have relevance to the above wide-ranging academic and commercial disciplines, and interests in chemistry, physics, biology and technology. In order to provide easy access to this vast and varied literature, each volume of Photochemistry comprises sect...
