  • The past decade has seen the field of proteomics expand from a highly technical endeavor to a widely utilized technique. The objective of this book is to highlight the ways in which proteomics is currently being employed to address issues in the biological sciences. Although there have been significant advances in techniques involving the utilization of proteomics in biology, fundamental approaches involving basic sample visualization and protein identification still represent the principle techniques used by the vast majority of researchers to solve problems in biology.

  • The art of compliance is a craft much like that of a carpenter who learns to work with various kinds of wood and designs. Ours is an industry wrought with differences. While the regulations that govern FDA-regulated industries are proscribed, how the regulations are interpreted and applied really depends on experience and how well one has mastered the craft of compliance. There are no proscribed procedures, but there are guideposts common to all FDA-regulated industries, whether a firm manufactures medical devices, pharmaceuticals, or biological products....

  • This book, with its 16 chapters, documents the present state of knowledge of the adenosine A3 receptor. It covers a wide range of information, including data from studies of theoretical, molecular and cellular pharmacology, signal transduction, integrative physiology, new drug discoveries and clinical applications. It fills an important gap in the literature since no alternative source of such information is currently available.

  • Drug abuse in the developed world is an international problem. In the USA, in an effort to deter drug use and identify abusers so they may receive treatment, testing an individual’s urine has become a large commercial enterprise. Drug testing has also been a traditional part of clinical care in medicine and in the medicolegal investigation of death. While scientists conducting drug testing in the postmortem arena routinely analyze a variety of biological matrices, the specimen of choice in the drug testing industry in the USA is urine and in clinical medicine, serum.

  • Agricultural biotechnology offers great promise for Africa and tissue culture and marker-assisted selection are already in widespread use across the continent. However, the safe application of these technologies requires functioning biosafety systems. The report focuses on the special issues related to biosafety in Africa.Crops can be improved by conventional breeding, by tissue culture and by marker-aided selection. But for many improvements - such as drought and salinity tolerance - GM technology is going to be essential.

  • Ten years ago when I wrote the foreword to the first edition of this book, the concept of women’s health was changing at a rapid pace. The focus was just shifting from solely reproductive issues and biological factors, to an expanded perception that women’s health encompasses biological, familial, cultural, economic, emotional, psychological, and behavioral elements of each woman and her sociopolitical environment, beyond just the reproductive organs and across her entire lifespan.

  • Global agriculture is now at the crossroads. The Green Revolution of the last century that gave many developing countries such as India a breathing spell, enabling them to adjust the growth of their human populations better to the supporting capacity of their ecosystems, is now in a state of fatigue. Average growth rates in food production as well as factor productivity in terms of yield per unit of mineral fertilizer (NPK) are both declining.

  • However, despite sharing a common signature CLLs expressing mutated and unmutated IgVH genes differentially express more than 100 genes. Among these, over-expression of genes encoding zeta-chain-associated protein 70 (ZAP-70), lipoprotein lipase (LPL), BCL-7a, dystrophin and gravin are observed in the aggressive unmutated cases, while stable mutated cases over-express Wnt3, CTLA-4, NRIP1 nuclear receptor gene, ADAM29 and the transcription factor TCF7 [53]. These results suggest that indolent mutated and aggressive unmutated CLLs constitute two variants of the same disease.

  • The New Biology set consists of the following six volumes: The Cell, Animal Cloning, Stem Cell Research, Gene Therapy, Cancer, and Aging. The set is intended primarily for middle and high school students, but it is also appropriate for first-year university students and the general public. In writing this set, I have tried to balance the need for a comprehensive presentation of the material, covering many complex fields, against the danger of burying—and thereby losing—young students under a mountain of detail.

  • This edition aims to present some relevant topics in the histopathology area that may be of interest for medical doctors and for other professionals interested in pathology. Histopathology applies basic knowledge obtained from biologic and anatomic science to make diagnosis, to determine the severity and progress of a condition and to evaluate the possible response to certain therapies. Thus, it is not surprising that this discipline constantly expands with progresses produced in biology.

  • Rarely in the modern history of humans has biology played such an important role in human affairs as it does today. In the eighteenth and nineteenth centuries, explorers stimulated the first major advance in biology by bringing back countless new species that Darwin, and others, put into a logical order based on the theory of natural selection. The development of evolutionary thinking and the clarification of the rules of genetic inheritance resulted in the theoretical base for targeted artificial selection—an essential component of progress in biology and agriculture....
