Eukaryotic Membranes and Cytoskeleton : Origins and Evolution

Eukaryotic Membranes and Cytoskeleton: Origins and Evolution discusses the evolutionary origin and diversification of eukaryotic endomembranes and cytoskeleton from a cell biological and comparative genomic perspective. Many of the chapters present original research data from comparative genomic surveys. The presence/absence of gene families with central roles in endomembrane and cytoskeleton dynamics in a variety of eukaryotic taxa and an understanding of eukaryote phylogeny allow us to accurately reconstruct the cellular machineries present in the last common ancestor of eukaryotes. Such a reconstruction is fundamental if we are to understand eukaryotic diversification since this is the ancestral cell from which all diversity arose. Comparative genomics can likewise tell us which lineages expanded or reduced certain gene families and the associated cellular machineries.

Ethylene Action in Plants

The plant hormone ethylene plays a prominent role among several intrinsic and extrinsic factors that control growth and physiology of plants. Its biological activity was discovered over a century ago. However, extensive studies on its mode of action came later. To date, it is well documented that ethylene is a versatile signaling molecule that plays an important role in many physiological processes - like growth, senescence, fruit ripening, stress responses, symbioses, and photosynthesis. Molecular-genetic analyses have revealed mechanisms responsible for ethylene production, perception, and signal transduction. The present work brings into focus the recent developments on the biochemical, physiological, and molecular basis for ethylene action in plants.

Ethics in Agriculture : An African Perspective

The role of biotechnology in African agriculture has become a contentious issue. The ethical issues in agriculture in Africa do not focus only on biotechnology. The role of nutrition in the persistence of HIV/AIDS is highly debated and sometimes controversial. Land-related issues also generate heated debates in communities and amongst policy-makers. The single core that runs through all of these and many other related issues is, what are ethically acceptable solutions to these problems? This book attempts, in simple, unambiguous terms, to discuss the most important issues in African agriculture that have an ethical thread.

Establishing medical reality : Essays in the metaphysics and epistemology of biomedical science

This volume approaches the philosophy of medicine from the broad naturalist perspective that holds that philosophy must be continuous with, constrained by, and relevant to empirical results of the natural and social sciences and that believes that the history, sociology, politics, and ethics of science provide relevant information for philosophical analysis. One traditional topic covered by several of the contributions is the nature of disease, but the approach is largely from the philosophy of science rather than traditional linguistic analysis. The complex interplay of epistemological and sociological factors in producing evidence in medicine is discussed by chapters on collective medical discussion making, experimental medicine, " genetic" diseases, mental illness, and race and gender categories. The upshot is a volume that ties medicine to contemporary issues in philosophy of science and metaphysics like no other.

Erythropoietins and Erythropoiesis : Molecular, Cellular, Preclinical, and Clinical Biology

The book is divided into two sections: Background and Basic Science and Clinical Uses of Recombinant Erythropoietins. To begin, Israels and Israels describe the biology of red cells, the hierarchy of erythropoietic progenitor cells, their development to mature cells, and the effects of endogenous EPO on their development. Foote summarizes the historical interest in, and search for, an erythropoietic factor. Once EPO was identified,cloned,and expressed,the path was set for the study of other aspects of EPO biology both within e- thropoiesis and other cellular systems.

Environmental Effects of Afforestation in North-Western Europe : From Field Observations to Decision Support

Recognising the need for effective decision making in relation to land-use change, this timely book develops a series of tools for estimating the environmental impacts of afforestation. It also presents guidelines and decision support systems (DSS) to enable both policy makers and forest managers to maximize the benefits and minimize the adverse effects of afforestation. This book will provide a valuable resource for both graduate students and researchers in forest, environmental and biological sciences, as well as for landscape planners and policy makers involved in afforestation projects at local, regional and international levels.

Environmental and Microbial Relationships

After the publication of Volume IV in 1997, the introduction of molecular methods into ecology led to significant new findings. Emphasizing these advances, the chapters for the second edition have been completely updated and revised. This volume provides insight into current research on fungal populations and communities. It focuses on fungal responses to the physical environment, interactions with other fungi, microorganisms and invertebrates, the role of fungi in ecosystem processes such as decomposition and nutrient cycling, and aspects of biogeography and conservation. Several chapters deal with various applications in, e.g. biological pest control, natural products discovery, and the degradation of toxic organic compounds. This is an invaluable source of information both for scientists who wish to update their knowledge of current progress and for graduate students interested in obtaining a first overview of this field of research.

Entry Inhibitors in HIV Therapy

The introductory chapters of this book present an overview of entry inhibitors, review current knowledge of how Env mediates entry, and discuss the challenge of genetic diversity in this region of the viral genome. Subsequent chapters feature current information on individual classes of entry inhibitors that target each step of the virus entry pathway, from attachment to membrane fusion. There is an emphasis on the complex determinants of entry inhibitor susceptibility, resistance mechanisms, the need for clinical phenotyping, and how these issues create new challenges for antiretroviral therapy. Encouraging pre-clinical studies of entry inhibitors as microbicidesare also discussed. The final chapters highlight the current status of entry inhibitors in clinical studies, the major milestone achieved with FDA approval of enfuvirtide, and review drug development, past and present.

Entomology

The author’s long-held belief that an introductory entomology course should present a balanced treatment of the subject is reflected in the continued arrangement of the book in four sections: Evolution and Diversity, Anatomy and Physiology, Reproduction and Development, and Ecology. For the third edition, all chapters have been updated. This includes not only the addition of new information and concepts but also the reduction or exclusion of material no longer considered "mainstream", so as to keep the book at a reasonable size.

Enhancing the Dissolution Rate of Atorvastatin by Solid Dispersion Technique

In the last few decades, solid dispersion (SD) technology had been studied as an approach to produce an amorphous carrier to enhance the solubility, dissolution rate, and bioavailability of poorly water-soluble drugs. The use of suitable carrier and methodology in the preparation of SDs play a significant role in the biological behavior of the SDs. Atorvastatin is a statin group HMG-CoA reductase inhibitor drug that is commonly used to adverse cardiovascular events and to lower blood total cholesterol and LDL-cholesterol. the solubility of atorvastatin in water is very low (0.1 mg mL− 1), which results in reduced bioavailability. In order to enhance its solubility, we have prepared solid dispersions (SDs) of atorvastatin at different drug: polymer ratios (1:2, 1:10, 1:20,1:25 and 1:40), using polyethylene glycol 6000 as polymer and different preparation methods (co-precipitate and melting methods) The characterization of the SDs was performed using differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR) The solubility of AT was improved by the incorporation PEG6000.
