Available in PDF, EPUB and Kindle. Book excerpt: This treatise had its origins in the authors' strong opinion that the discovery of new drugs, especially of innovative therapeutic agents, really does not happen as a spontaneous sequel to investiga tive research, no matter how penetrating such research may be. Rather, it seemed to us that the discovery of innovative therapeutic agents was a very active process, existing in and of itself, and demanding full attention-it was not simply a passive, dependent by-process of investigative research. And yet, many researchers some close confreres of the authors, others more distant-believed otherwise. We felt that their view reflected unrealistic thinking and that reality probably lay closer to what Beyer" maintained: We are taught to believe that if we can understand a disease it should be easy enough to figure out, say, the molecular configuration of a definitive receptor mechanism somewhere along the line and to design a specific drug . . . . And so we start out to understand the disease but never get around to doing much about therapy. The authors very soon realized that there was essentially no quantitive information available on just where and how innovative therapeutic agents were discovered. There were only anecdotal accounts, and these were able to be selected and presented in ways that could be used to defend any point of view.

Available in PDF, EPUB and Kindle. Book excerpt: Although the history of photomedicine dates back thousands of years, with even preliterate cultures appreciating the healing properties of sunlight, for many workers in the discipline photomedicine is associated with the observation about 100 years ago of Niels Finsen, a Danish physician. Finsen recognized that people with tuberculosis who lived in Norway and who had very little exposure to sunlight often developed facial lesions (lupus vulgaris) which would decrease and sometimes disappear during the summer months. This very observant physician reasoned that artificial light ought to produce the same effect as sunlight and began utilizing the radiation from the newly available carbon arc. At first, he used a glass lens to concentrate the radiation, but since this produced considerable burning, he replaced this with a hollow glass lens filled with water. However, while this reduced the heat burns, it did not actually duplicate the effect of direct sunlight. Finally, using a hollow lens filled with water but equipped with quartz windows, Finsen was able to imitate, even improve upon, the effect of sunlight. As a result, lupus vulgaris was practically eliminated from the Scandinavian countries.

Download or read book Chemical Treatise on Air and Fire written by Carl Wilhelm Scheele and published by . This book was released on 2009-01 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carl Wilhelm Scheele (1742-1786) was a German-Swedish pharmaceutical chemist, born in Stralsund, Western Pomerania, Germany. Instead of becoming a carpenter like his father, Scheele decided to become a pharmacist. His career began with his apprenticeship at an apothecary in Gothenburg when he was only fourteen years old. He retained this position for eight years before becoming an apothecary's clerk in Malmo. Then Scheele worked as a pharmacist in Stockholm, from 1770-1775 in Uppsala, and later in Koping. In 1776, he was able to establish his own pharmacy. He was the discoverer of many chemical substances, most notably discovering oxygen (although Joseph Priestley published his findings first), molybdenum and chlorine before Humphry Davy. Scheele described the discovery of oxygen and nitrogen (1772-1773), in his only book, Chemische Abhandlung von der Luft und dem Feuer (Chemical Treatise on Air and Fire) in 1777. He called it "fire air" because it supported combustion, but he explained oxygen using phlogistical terms because he did not believe that his discovery disproved the phlogiston theory.

Download or read book Microdosimetry written by Lennart Lindborg and published by CRC Press. This book was released on 2017-07-06 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental microdosimetry deals with the measurement of charged particle energy deposition in tissue equivalent volumes, ranging in size from nanometres to micrometres. Microdosimetry is employed to improve our understanding of the relationship between radiation energy deposition, the resulting biological effects, and the appropriate quantities to be used in characterizing and quantifying radiation quality. Although many reviews and contributions to the field have been published over the past fifty years, this new book is the first to provide a single, up to date, and easily accessible account of experimental microdosimetry. This book is designed to be used in medical, radiation, and health physics courses and by Master’s and PhD students. In addition to serving as an introductory text to the field for graduate students, this book will also be of interest as a teaching and reference resource for graduate supervisors and established researchers. Drs. Lennart Lindborg and Anthony Waker have spent a life-time career in experimental microdosimetry research in academic, industrial and regulatory environments and have observed the development of the field from its early days as a recognized discipline; they bring to this book particular knowledge and experience in the design, construction, operation and use of tissue equivalent gas ionization counters and chambers.
