Advances in polymer science have led to the development of novel drug delivery systems. Some polymers are obtained from natural resources and then chemically modified for various applications, while others are chemically synthesized and used. A large number of natural and synthetic polymers are available. In the present paper, only water soluble polymers are described.
Social and Economic Factors that Influence Our Health and Contribute to Health Inequalities What makes — and keeps — us healthy If good health is not shared equally by Canadians, then understanding the many factors — or determinants — that contribute to health and differences in health status is essential to identifying and implementing solutions to this challenge.
