Natural Products Isolation


Book Description

The term “natural products” spans an extremely large and diverse range of chemical compounds derived and isolated from biological sources. Our interest in natural products can be traced back thousands of years for their usefulness to humankind, and this continues to the present day. Compounds and extracts derived from the biosphere have found uses in medicine, agriculture, cosmetics, and food in ancient and modern societies around the world. Therefore, the ability to access natural products, understand their usefulness, and derive applications has been a major driving force in the field of natural product research. The first edition of Natural Products Isolation provided readers for the first time with some practical guidance in the process of extraction and isolation of natural products and was the result of Richard Cannell’s unique vision and tireless efforts. Unfortunately, Richard Cannell died in 1999 soon after completing the first edition. We are indebted to him and hope this new edition pays adequate tribute to his excellent work. The first edition laid down the “ground rules” and established the techniques available at the time. Since its publication in 1998, there have been significant developments in some areas in natural product isolation. To capture these developments, publication of a second edition is long overdue, and we believe it brings the work up to date while still covering many basic techniques known to save time and effort, and capable of results equivalent to those from more recent and expensive techniques.




Post-Ottoman Coexistence


Book Description

In Southeast Europe, the Balkans, and Middle East, scholars often refer to the “peaceful coexistence” of various religious and ethnic groups under the Ottoman Empire before ethnonationalist conflicts dissolved that shared space and created legacies of division. Post-Ottoman Coexistence interrogates ways of living together and asks what practices enabled centuries of cooperation and sharing, as well as how and when such sharing was disrupted. Contributors discuss both historical and contemporary practices of coexistence within the context of ethno-national conflict and its aftermath.

Klinefelter’s Syndrome


Book Description

Klinefelter's syndrome occurs relatively frequently, being diagnosed for one in 600 male infants, yet it is probably very rare that it is recognized early enough to make effective treatment possible. Often the person afflicted does not go to a doctor until physical and emotional disturbances have developed on the ba sis of the syndrome. The appropriate therapy at the correct time can prevent many of these disturbances. In our andrology outpatient clinic we encountered Klinefelter's syndrome almost three decades ago in patients suffering from impotentia generandi. It was not until later that we dealt with it in our capacities as dematologists. It was observed at a rate too high to be coincidental among younger men suffer ing from ulcera crurum. On the other hand, we failed to see the condition during our work as con sultants in other specialities, especially internal medicine, although we re peatedly attempted to identify it. We should have encountered it at least occa sionally in our 10 years working in the Munich hospitals with their more than 4000 beds. It was this imbalance between the allegedly relative frequency of this condition and its rare detection which led us to plan a Klinefelter sympo sium. We soon determined, during a first search of the literature, that there was information in many more subject areas that we had expected or even guessed.




Uveitis


Book Description

This new edition expands on the diagnostic and therapeutic approaches to uveitis. New fluorescein angiograms and indocyanine angiograms are presented, and descriptive case studies provide examples relevant to the treatment of patients with uveitis. Now with 79 color photographs, the book is even more thorough in its coverage of the medical, pharmacological, and surgical treatment of uveitis. You will also find the most up-to-date information on other conditions associated with uveitis, including inflammatory complications of AIDS. A Brandon Hill Title




Sociocultural Research on Mathematics Education


Book Description

This volume--the first to bring together research on sociocultural aspects of mathematics education--presents contemporary and international perspectives on social justice and equity issues that impact mathematics education. In particular, it highlights the importance of three interacting and powerful factors--gender, social, and cultural dimensions. Sociocultural Research on Mathematics Education: An International Perspective is distinguished in several ways: * It is research based. Chapters report on significant research projects; present a comprehensive and critical summary of the research findings; and offer a critical discussion of research methods and theoretical perspectives undertaken in the area. * It is future oriented, presenting recommendations for practice and policy and identifying areas for further research. * It deals with all aspects of formal and informal mathematics education and applications and all levels of formal schooling. As the context of mathematics education rapidly changes-- with an increased demand for mathematically literate citizenship; an increased awareness of issues of equity, inclusivity, and accountability; and increased efforts for globalization of curriculum development and research-- questions are being raised more than ever before about the problems of teaching and learning mathematics from a non-cognitive science perspective. This book contributes significantly to addressing such issues and answering such questions. It is especially relevant for researchers, graduate students, and policymakers in the field of mathematics education.
