Oral Colon-Specific Drug Delivery


Book Description

Oral Colon-Specific Drug Delivery covers approaches used to deliver a variety of drugs to the colon. Anatomy and physiology of the gastrointestinal tract as it affects colonic drug delivery and pharmacokinetics are reviewed, as well as drug absorption from the colon. The book presents valuable information on a variety of topics, including oral peptide/protein delivery, dextran-based delivery systems, glycoside/glycosidase-based delivery, azo-bond prodrugs, hydroxypropyl methacrylamide copolymers for colonic delivery, and matrices for colonic drug delivery. Special emphasis is placed on delivery systems, especially biochemical approaches to delivery, such as the use of degradable polymers and both low and high molecular weight prodrugs. Oral Colon-Specific Drug Delivery will provide a valuable reference resource for gastroenterologists, pharmaceutical scientists, and other researchers working with drug delivery to the colon.













Local-spinal Therapy of Spasticity

His discovery, however, marks the Corning, by blocking the neural con onset of the era of regional anaesthesia. It took almost one hundred years until his duction to the hind extremities of a dog by injecting cocaine-solution into the lumbar original idea of "local medication of the vertebral interspace, was the first to per cord" was again reconsidered due to two form spinal (or epidural?) anaesthesia [1]. reasons: At that time, he was unaware of the local I. The discovery of different drug receptors anaesthetic properties of cocaine (dis in the spinal cord made it possible, by in covered in the same year by C.

Implantable devices for long-term appli proximity of the central nervous system, i. e. cation of drugs to specific sites of the spinal cord, in order to treat or even heal body, including the spinal spaces, were developed during the 1970's.




On Coexistence


Book Description

Competition experiments in the field show that Plantago lanceolata and Chrysanthemum leucanthemum occupy partly different niches in time. The yield of P. lanceolata decreased after two years, probably by senescence and auto-inhibition. The reaction of C. leucanthemum to this caused high Relative Yield Total (RYT), but there was no equilibrium.







How Intelligence Happens


Book Description

A lively journey through the brain’s inner workings from “one of the world’s leading cognitive neuroscientists” (The Wall Street Journal). Human intelligence builds sprawling cities, vast cornfields, and complex microchips. It takes us from the atom to the limits of the universe. How does the biological brain, a collection of billions of cells, enable us to do things no other species can do? In this book, neuroscientist John Duncan offers an adventure story—the story of the hunt for basic principles of human intelligence, behavior, and thought. Using results drawn from classical studies of intelligence testing; from attempts to build computers that think; from studies of how minds change after brain damage; from modern discoveries of brain imaging; and from groundbreaking recent research, he synthesizes often difficult-to-understand information into clear, fascinating prose about how brains work. Moving from the foundations of psychology, artificial intelligence, and neuroscience to the most current scientific thinking, How Intelligence Happens is “a timely, original, and highly readable contribution to our understanding” (Nancy Kanwisher, MIT) from a winner of the Heineken Prize for Cognitive Science
