Application of recent advances, such as non-equilibrium thermodynamics, the maintenance concept and the material balancing method, to the description, of microbial growth has suggested new experimental approaches which have yielded a wealth of data. These data have been used to develop mathematical models of microbial growth and metabolism, and the models have made it possible to direct the metabolism of a microorganism in such a way that more of a certain desired product is made. While a full quantitative description of all aspects of microbial growth and metabolism is till remote, the new approaches are opening up large areas of new potential -- it is now possible, for instance, to deal with individual cells in a population and with quantitative aspects of product formation and optimisation. Microbiologists, biochemists and physiologists will find this an invaluable update on a field of great promise.
This is the third of three planned volumes in the Methods in
Enzymology series on the topic of stem cells. This volume is a
unique anthology of stem cell techniques written by experts from
the top laboratories in the world. The contributors not only have
hands-on experience in the field but often have developed the
original approaches that they share with great attention to detail.
The chapters provide a brief review of each field followed by a
"cookbook" and handy illustrations. The collection of protocols
includes the isolation and maintenance of stem cells from various
species using "conventional" and novel methods, such as derivation
of ES cells from single blastomeres, differentiation of stem cells
into specific tissue types, isolation and maintenance of somatic
stem cells, stem cell-specific techniques and approaches to tissue
engineering using stem cell derivatives. The reader will find that
some of the topics are covered by more than one group of authors
and complement each other. Comprehensive step-by-step protocols and
informative illustrations can be easily followed by even the least
experienced researchers in the field, and allow the setup and
troubleshooting of these state-of-the-art technologies in other
laboratories.
Today, in the era of the statins (cholesterol lowering drugs),
there is no longer any doubt about the value of lowering blood
cholesterol levels. This book chronicles the controversy that
swirled around the 'lipid hypothesis' of atherosclerosis for so
many years. In fact, 'the lower the better' is the position of many
clinicians. However, getting to this point has been a long uphill
battle marked by heated debate and sometimes violent disagreement.
The history of this controversy is told here for its own sake and
because remembering it may help us avoid similar mistakes in the
future.
This review series covers trends in modern biotechnology, including all aspects of this interdisciplinary technology, requiring knowledge, methods, and expertise from chemistry, biochemistry, microbiology, genetics, chemical engineering and computer science.
This volume includes, in an integrated way, modern computational studies of nucleic acids, ranging from advanced electronic structure quantum chemical calculations through explicit solvent molecular dynamics (MD) simulations up to mesoscopic modelling, with the main focus given to the MD field.It gives an equal emphasis to the leading methods and applications while successes as well as pitfalls of the computational techniques are discussed. The systems and problems studied include: Accurate calculations of base pairing energies; Electronic properties of nucleic acids and electron transfer, through various types of nucleic acid; and, Calculating DNA elasticity. This book is ideally suited to academics and researchers in organic and computational chemistry as well as biochemistry and particularly those interested in the molecular modelling of nucleic acids.Besides the state-of-the art science, the book also provides introductory information to non-specialists to enter this field.
This book focuses primarily on the role of interfacial forces in understanding biological phenomena at the molecular scale. By providing a suitable statistical mechanical apparatus to handle the biomolecular interface, the book becomes uniquely positioned to address core problems in molecular biophysics. It highlights the importance of interfacial tension in delineating a solution to the protein folding problem, in unravelling the physico-chemical basis of enzyme catalysis and protein associations, and in rationally designing molecular targeted therapies. Thus grounded in fundamental science, the book develops a powerful technological platform for drug discovery, while it is set to inspire scientists at any level in their careers determined to address the major challenges in molecular biophysics. The acknowledgment of how exquisitely the structure and dynamics of proteins and their aqueous environment are related attests to the overdue recognition that biomolecular phenomena cannot be effectively understood without dealing with interfacial behaviour. There is an urge to grasp how biologically relevant behaviour is shaped by the structuring of biomolecular interfaces and how interfacial tension affects the molecular events that take place in the cell. This book squarely addresses these needs from a physicist perspective. The book may serve as a monograph for practitioners and, alternatively, as an advanced textbook. Fruitful reading requires a background in physical chemistry and some basics in biophysics. The selected problems at the end of the chapters and the progression in conceptual difficulty make it a suitable textbook for a graduate level course or an elective course for seniors majoring in chemistry, physics, biomedical engineering or related disciplines.
Interplay between Metal Ions and Nucleic Acids provides in an authoritative and timely manner in 12 stimulating chapters, written by 24 internationally recognized experts from 8 nations, and supported by nearly 1500 references, about 20 tables, and 125 illustrations, many in color, a most up-to-date view on metal ion-nucleic acid interactions; the characterization of which is covered in solution and in the solid state. The volume concentrates on modern developments encompassing topics in the wide range from G-quadruplexes via DNAzymes, catalysis at the DNA scaffold, and metal-mediated base pairs to peptide nucleic acids (PNAs) being thus of relevance, e.g., for chemistry and nanotechnology but also for molecular biology and (genetic) diagnostics.

The NATO ARW "Molecular Self-Organization in Micro-, Nano-, and Macro- Dimensions: From Molecules to Water, to Nanoparticles, DNA and Proteins" to commemorate Professor Alexander S. Davydov was held in Kiev, Ukraine, on 8-12 June, 2008, at the Bogolyubov Institute for Theoretical Physics of the National Academy of Sciences of Ukraine. Theobjective ofthisNATOARWistounveilandformulatetheprincipalfeatures that govern myriads of the molecular self-organization processes in micro-, nano-, and macro-dimensions from the following key representatives such as liquid - ter and aqueous solutions, and molecular liquids, nanodots, nanoparticles including gold, solitons, biomolecules such as DNA and proteins, biopolymers and bios- sors, catalysis, molecular modeling, molecular devices, and thin ?lms, and to offer another, more advanced directions in computational, experimental, and technolo- cal areas of nano- and bioscience towards engineering novel and powerful molecular self-organized assemblies with tailored properties. Nanoscience is indeed one of the most important research and development fr- tiers in modern science. Simplistically, nanoscience is the science of small particles of materials of a size of nanometre. Molecular nanoscience and nanotechnology have brought to us the unprecedented experimental control of the structure of matter with novel extraordinary properties that open new horizons and new opportunities, and new ways to make things, particularly in our everyday life, to heal our bodies, and to care of the environment. Unfortunately, they have also brought unwelcome advances in weaponry and opened yet more ways to foul up the world on an en- mous scale.
The ability of polypeptides to form alternatively folded, polymeric
structures such as amyloids and related aggregates is being
increasingly recognized as a major new frontier in protein
research. This new volume of Methods in Enzymology along with Part
C (volume 413) on Amyloid, Prions and other Protein Aggregates
continue in the tradition of the first volume (309) in containing
detailed protocols and methodological insights, provided by leaders
in the field, into the latest methods for investigating the
structures, mechanisms of formation, and biological activities of
this important class of protein assemblies.
Population genomics is a recently emerged discipline, which aims at understanding how evolutionary processes influence genetic variation across genomes. Today, in the era of cheaper next-generation sequencing, it is no longer as daunting to obtain whole genome data for any species of interest and population genomics is now conceivable in a wide range of fields, from medicine and pharmacology to ecology and evolutionary biology. However, because of the lack of reference genome and of enough "a priori" data on the polymorphism, population genomics analyses of populations will still involve higher constraints for researchers working on non-model organisms, as regards the choice of the genotyping/sequencing technique or that of the analysis methods. Therefore, "Data Production and Analysis in Population Genomics" purposely puts emphasis on protocols and methods that are applicable to species where genomic resources are still scarce. It is divided into three convenient sections, each one tackling one of the main challenges facing scientists setting up a population genomics study. The first section helps devising a sampling and/or experimental design suitable to address the biological question of interest. The second section addresses how to implement the best genotyping or sequencing method to obtain the required data given the time and cost constraints as well as the other genetic resources already available, Finally, the last section is about making the most of the (generally huge) dataset produced by using appropriate analysis methods in order to reach a biologically relevant conclusion. Written in the successful "Methods in Molecular Biology " series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, advice on methodology and implementation, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, "Data Production and Analysis in Population Genomics" serves a wide readership by providing guidelines to help choose and implement the best experimental or analytical strategy for a given purpose.

In the past decade, there has been an explosion of progress in understanding the roles of carbohydrates in biological systems. This explosive progress was made with the efforts in determining the roles of carbohydrates in immunology, neurobiology and many other disciplines, examining each unique system and employing new technology. This volume represents the second of three in the Methods in Enzymology series, including Glycobiology (vol. 415) and Glycomics (vol. 416), dedicated to disseminating information on methods in determining the biological roles of carbohydrates. These books are designed to provide an introduction of new methods to a large variety of readers who would like to participate in and contribute to the advancement of glycobiology. The methods covered include structural analysis of carbohydrates, biological and chemical synthesis of carbohydrates, expression and determination of ligands for carbohydrate-binding proteins, gene expression profiling including micro array, and generation of gene knockout mice and their phenotype analyses.
Plants play a key role in purifying the biosphere of the toxic effects of industrial activity. This book shows how systematic application of the results of investigations into the metabolism of xenobiotics (foreign, often toxic substances) in plants could make a vastly increased contribution to planetary well-being. Deep physiological knowledge gained from an accumulation of experimental data enables the great differences between the detoxifying abilities of different plants for compounds of different chemical nature to be optimally exploited. Hence planting could be far more systematically adapted to actual environmental needs than is actually the case at present. The book could form the basis of specialist courses in universities and polytechnics devoted to environmental management, and advanced courses in plant physiology and biochemistry, for botany and integrative biology students. Fundamental plant physiology and biochemistry from the molecular level to whole plants and ecosystems are interwoven in a powerful and natural way, making this a unique contribution to the field.
The critically acclaimed laboratory standard for more than forty years, Methods in Enzymology is one of the most highly respected publications in the field of biochemistry. Since 1955, each volume has been eagerly awaited, frequently consulted, and praised by researchers and reviewers alike. Now with more than 300 volumes (all of them still in print), the series contains much material still relevant today-truly an essential publication for researchers in all fields of life sciences.
This book focuses on an "outside the box" notion by utilizing the powerful applications of next-generation sequencing (NGS) technologies in the interface of chemistry and biology. In personalized medicine, developing small molecules targeting a specific genomic sequence is an attractive goal. N-methylpyrrole (P)-N-methylimidazole (I) polyamides (PIPs) are a class of small molecule that can bind to the DNA minor groove. First, a cost-effective NGS (ion torrent platform)-based Bind-n-Seq was developed to identify the binding specificity of PIP conjugates in a randomized DNA library. Their biological influences rely primarily on selective DNA binding affinity, so it is important to analyze their genome-wide binding preferences. However, it is demanding to enrich specifically the small-molecule-bound DNA without chemical cross-linking or covalent binding in chromatinized genomes. Herein is described a method that was developed using high-throughput sequencing to map the differential binding sites and relative enriched regions of non-cross-linked SAHA-PIPs throughout the complex human genome. SAHA-PIPs binding motifs were identified and the genome-level mapping of SAHA-PIPs-enriched regions provided evidence for the differential activation of the gene network. A method using high-throughput sequencing to map the binding sites and relative enriched regions of alkylating PIP throughout the human genome was also developed. The genome-level mapping of alkylating the PIP-enriched region and the binding sites on the human genome identifies significant genomic targets of breast cancer. It is anticipated that this pioneering low-cost, high through-put investigation at the sequence-specific level will be helpful in understanding the binding specificity of various DNA-binding small molecules, which in turn will be beneficial for the development of small-molecule-based drugs targeting a genome-level sequence.

through its distinguished authors, up-to-date and detailed coverage
of particular classes or sources of alkaloids.
In this book, seven chapters describe studies aimed at understanding and exploiting the key features of such molecular RNA and DNA devices. In the first section of the book, four chapters are devoted to artificial nucleic acid switches and sensors. These chapters introduce the concept of allosteric ribozymes as molecular switches and sensors; describe nucleic acid enzymes that are switched by oligonucleotides and other nucleic acid enzymes that are switched by proteins; and illustrate how switching elements can be integrated rationally into fluorescently signaling molecular sensors made out of nucleic acids. In the second section of the book, three chapters show that nature has been as crafty a molecular-scale engineer as any modern scientist via evolution of natural nucleic acid switches and sensors. RNAs have been found whose activities are modulated either by proteins or by small-molecule metabolites, and both kinds of system are described. Finally, the notion of exploiting naturally occurring RNA switches for drug development is discussed.
Due to their rare combination of high chemical stability, exceptional optical and electrical properties, high surface-to-volume ratio, and high aspect ratio, carbon nanotubes (CNTs) have made an enormous impact on materials science, molecular biology, biomedicine, and bioanalytical chemistry. Carbon Nanotubes: Methods and Protocols provides reliable, consistent protocols on the application of CNTs in molecular biology-related fields. These are of vital importance, as the commercially available CNTs differ in purity, agglomeration state, as well as length and diameter distribution, all of which have a profound influence on the dispersability and surface properties of the tubes. The volume contains detailed sections on functionalization, toxicity, trafficking, scaffolds, and biosensors, provided by expert researchers from various fields. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Carbon Nanotubes: Methods and Protocols serves to contribute to the achievement of common standards and helps researchers to avoid discrepancies in future biology-related CNT studies.
The centromere is a chromosomal region that enables the accurate segregation of chromosomes during mitosis and meiosis. It holds sister chromatids together, and through its centromere DNA-protein complex known as the kinetochore binds spindle microtubules to bring about accurate chromosome movements. Despite this conserved function, centromeres exhibit dramatic difference in structure, size, and complexity. Extensive studies on centromeric DNA revealed its rapid evolution resulting often in significant difference even among closely related species. Such a plasticity of centromeric DNA could be explained by epigenetic c- trol of centromere function, which does not depend absolutely on primary DNA sequence. According to epigenetic centromere concept, which is thoroughly d- cussed by Tanya Panchenko and Ben Black in Chap. 1 of this book, centromere activation or inactivation might be caused by modifications of chromatin. Such acquired chromatin epigenetic modifications are then inherited from one cell di- sion to the next. Concerning centromere-specific chromatin modification, it is now evident that all centromeres contain a centromere specific histone H3 variant, CenH3, which replaces histone H3 in centromeric nucleosomes and provides a structural basis that epigenetically defines centromere and differentiates it from the surrounding chromatin. Recent insights into the CenH3 presented in this chapter add important mechanistic understanding of how centromere identity is initially established and subsequently maintained in every cell cycle. |
