Bioactive Marine Natural Products
Bioactive Marine Natural Products is the first book available that covers all aspects of bioactive marine natural products. It fills the void in the literature for bioactive marine natural products. The book covers various aspects of marine natural products and it is hoped that all the major classes of bioactive compounds are included. Different classes of marine organisms and the separation and isolation techniques are discussed. The chemistry and biology of marine toxins, peptides, alkaloids, nucleosides and prostanoids are discussed in detail. Biological, toxicological and clinical evaluations are also dealt with to ensure that the book may be adopted at any stage by any practicing organic chemist or biologist, working in academia or in R&D divisions of pharmaceutical companies. Each chapter in the book includes an abstract to highlight the major points discussed in the text and concluding remarks are given. References to books, monographs, review articles and original papers are provided at the end of each chapter.
Basic Guide to Dental Instruments
Provides a working inventory of dental instrumentation in common use in dental surgeries. A clear photograph of each instrument is included, and described according to name, usage, any relevant features and varieties. Each section is dedicated to a specific discipline or division of dentistry. Complete set-ups have been included at the end of most sections for various procedures. The coverage reflects instrumentation and accessory items used in general dental practice, routine hospital dental procedures and selected specialist settings.
Asymmetric Cell Division
Cell biologists have recently become aware that the asymmetry of cell division is an important regulatory phenomenon in the fate of a cell. During development, cell diversity originates through asymmetry; in the adult organism asymmetric divisions regulate the stem cell reservoir and are a source of the drift that contributes to the aging of organisms with renewable cell compartments. Because of the concept of semi-conservative DNA synthesis, it was thought that the distribution of DNA between daughter cells was symmetric. The analysis of the phenomenon in cells during mitosis, however, revealed the asymmetry in the distribution of the genetic material that creates the drift contributing to aging of mammals. On the other hand, cancer cells can originate from a deregulation of asymmetry during mitosis in particular during stem cell expansion. The book describes the phenomenon in different organisms from plants to animals and addresses its implications for the development of the organism, cell differentiation, human aging and the biology of cancers.
Archaeology at the millennium : A sourcebook
The sourcebook is divided into four substantive sections, each of which is introduced by a summary statement outlining the chapters in the section. Part I deals with the history of archaeology and the advance of archaeological theory. Part II ranges over the first four million years of our evolution as a cultural species and covers the first hominids to complex hunter-gatherers. Part III concerns the origins of agriculture and features discussions of such issues as craft production, the division of labor, warfare, and the rise of social inquality. Part IV analyzes the rise of states and empired in both the Old and New World; the archaeology of the classical Mediterranean states is also included in this section. A final chapter portends the future of archaeology.
Apoptosis, cell signaling, and human diseases : Molecular mechanisms ; Vol.1
Volume 1 is divided into two sections: “Malignant Transformation and Metastasis” and “Molecular Basis of Disease Therapy.” Volume 2 follows a similar structure and is divided into sections entitled “Kinases and Phosphate” and “Molecular Basis of Cell Death.” All of the contributors are at the forefront of scientific discovery, and the reviews they present systemically examine the most exciting and innovative aspects of their particular areas of expertise. Researchers will find these volumes of major benefit as they search for novel and more effective treatments for human diseases.
Anti Cancer medicines derived from plants
Cancer is a broad term. It describes the disease that results when cellular changes cause the uncontrolled growth and division of cells. Some types of cancer cause rapid cell growth, while others cause cells to grow and divide ata slower rate. Certain forms of cancer result in visible growths called tumors, while others, such as leukemia, do not. Most of the body’s cells have specific functions and fixed lifespans. While it may sound like a bad thing, cell death is part of a natural and beneficial phenomenon called apoptosis.
Advances in solid state physics ; Vol. 46
Many topical talks given at the numerous symposia are included. Most of these were organized collaboratively by several of the divisions of the Arbeitskreis. The topis range from zero-dimensional physics in quantum dots, molecules and nanoparticles over one-dimensional physics in nanowires and 1d systems to more applied subjects like optoelectronics and materials science in thin films.
Advanced Linear Algebra
For the third edition, the author has added a new chapter on associative algebras that includes the well known characterizations of the finite-dimensional division algebras over the real field (a theorem of Frobenius) and over a finite field (Wedderburn's theorem); polished and refined some arguments (such as the discussion of reflexivity, the rational canonical form, best approximations and the definitions of tensor products); upgraded some proofs that were originally done only for finite-dimensional/rank cases; added new theorems, including the spectral mapping theorem; considerably expanded the reference section with over a hundred references to books on linear algebra.
Actin-Binding Proteins and Disease
This volume, written by experts in the field, is the first to deal with the relationship between human disease and the actin cytoskeleton. It provides overviews of actin and selected actin-binding proteins, and then focuses on diseases that involve these proteins. Specific chapters deal with actin, cofilin, profilin, gelsolin and thymosin ¾4. Other chapters discuss the roles of multiple actin-binding proteins in cancer and metastasis, leukocyte disorders, and heart failure, and there is a chapter that describes how intracellular pathogens use the host actin cytoskeleton. This seminal volume is intended for researchers, clinicians, physicians, and graduate students in the fields of biochemistry, cell biology, microbiology, immunology, and genetics.
A life cycle for clusters? : The dynamics of agglomeration, change, and adaption
The phenomenon of non-random spatial concentrations of firms in one or few related sectors (clusters) is intensively debated in economic theory and policy. The euphoria about successful clusters however neglects that historically, many thriving clusters did deteriorate into old industrial areas. This book studies the determinants of cluster survival by analyzing their adaptability to change in the economic environment. Linking theoretic knowledge with empirical observations, a simulation model (based in the N/K method) is developed, which explains when and why the cluster's architecture assists or hampers adaptability. It is found that architectures with intermediate degrees of division of labour and more collective governance forms foster adaptability. Cluster development is thus path dependent as architectures having evolved over time impact on the likelihood of future survival.
