  • Chemical Defenses of Arthropods

    • 1st Edition
    • Murry Blum
    • English
    Chemical Defenses of Arthropods charts the significant progress in the study of chemical defenses in arthropods, a rapidly expanding area of chemical ecology. The book groups the defensive compounds secreted by arthropods based on their main functionalities and sequentially lists them according to their carbon numbers. Organized into 19 chapters, this volume begins with an overview of the defensive exudates of arthropods and how arthropods have exploited these compounds to deter the ubiquitous and omnipresent predators around them. The next chapters introduce the reader to the defensive compounds produced in the exocrine glands of arthropods, ranging from alcohols and ketones to hydrocarbons, carboxylic acids, esters, 1,4-quinones and hydroquinones, lactones, phenols, steroids, and proteinaceous venoms. The book also discusses the taxonomic value of arthropod defensive compounds, with emphasis on factors affecting the composition of defensive secretions and taxonomic correlations that utilize them. Later chapters focus on arthropod biosynthesis of exocrine compounds, how insects tolerate the presence of plant toxins in their diets, and identified defensive compounds in arthropods. The book concludes with an analysis of the properties and characteristic distributions of arthropod natural products, along with their adaptiveness as defensive agents. This book is a valuable resource for biologists and chemists.

These contributions are organized into seven parts. Part I contains studies T cell receptors. Part II presents studies on T cell subpopulations. Parts III and IV examine helper T cells. Parts V and VI deal with suppressor T cells. Part VII contains papers on regulatory T cell circuits.

  • Biology of Perceptual Systems

    • 1st Edition
    • Edward Carterette
    • English
    Handbook of Perception, Volume III: Biology of Perceptual Systems reviews the literature on the biological aspects of human perception, with emphasis on perceptual systems and elements of sensory physiology. This volume is organized into 19 chapters and begins with a discussion of energy transduction, detection, and discrimination, along with the properties of neurons alone and as conjoined in nets. The focus then shifts to psychogenesis, the relatively new field of ethology, and the natural diversity and evolutionary divergence of sensory systems. The chapters that follow examine the genetics of behavior, the facts and theories about the way in which animals and men construct patterned stimulation of receptors into significant objects, and the structure and function of sensory systems on which vertebrates depend for their construction of the varieties of experience. The book methodically introduces the reader to chemoreception, tasting and smelling, cutaneous mechanoreception (of position, velocity, transients), active texture perception, mechanisms of spatial orientation and of motion in space, thermoreception, vision, and audition. In almost every case the underlying physiological mechanisms are related to the psychophysical or perceptual observations. This book is a valuable resource for psychologists, biologists, and natural scientists, as well as for those who are interested in the biology of human perception.

  • Base-Catalyzed Reactions of Hydrocarbons and Related Compounds

    • 1st Edition
    • Herman Pines
    • English
    Base-Catalyzed Reactions of Hydrocarbons and Related Compounds focuses on the use of bases as catalysts for the conversion of hydrocarbons and related compounds. In order to emphasize the broad scope of base-catalyzed reactions, examples dealing with the conversion of non-hydrocarbons are given. Comprised of 14 chapters, this book begins with a historical overview of base-catalyzed conversions of hydrocarbons, followed by a discussion on the isomerization of olefins, acetylenes, and allenes, as well as the dimerization and oligomerization of hydrocarbons. The reader is then introduced to a variety of reactions, including those between aromatic hydrocarbons and olefins and between alkylpyridines and alkenylpyridines; homogeneous carbon-carbon addition reactions; and reactions of aprotic solvents with olefins. Subsequent chapters explore carbon-carbon addition of olefins with miscellaneous compounds; addition of ammonia, amines, and anilines to olefinic hydrocarbons; hydrogenation and oxygenation; dehydrogenation, aromatization, and hydrogen transfer; and dehydration of alcohols. This monograph will be of interest to chemists.

  • Perturbations in the Spectra of Diatomic molecules

    • 1st Edition
    • Helene Lefebvre-Brion
    • English
    Perturbations in the Spectra of Diatomic Molecules examines in sufficient detail the spectrum of every diatomic molecule. This book is divided into seven chapters. Chapter 1 describes the perturbations and simple procedures for evaluating matrix elements of angular momentum. The terms in the molecular Hamiltonian that are responsible for perturbations are elaborated in Chapter 2, while the process of reducing spectra to molecular constants and the difficulty of relating empirical parameters to terms in the exact molecular Hamiltonian are described in Chapter 3. Chapter 4 discusses the magnitudes and physical interpretations of matrix elements. The transition intensities, especially quantum mechanical interference effects, are reviewed in Chapter 5. The last two chapters are devoted to the two forms of perturbation—prediss... and autoionization. This publication is a good source for graduate students, theorists, experimentalists, and potential users of spectroscopic data.

  • Chromosomal Proteins And Their Role In The Regulation Of Gene Expression

    • 1st Edition
    • Gary Stein
    • English
    Chromosomal Proteins and Their Role in the Regulation of Gene Expression examines how chromosomal proteins take part in the regulation of gene expression. This book also looks at the variety of approaches that are used in studying the structural and functional properties of chromosomal proteins, particularly as they relate to the control of transcription. This text is organized into 15 chapters and begins by analyzing the regulation of histone gene expression during the cell cycle and the role of non-histone chromosomal proteins in such regulation. The following chapters focus on the in vitro transcription of the globin gene in mouse fetal liver chromatin; the involvement of non-histone proteins in both positive and negative controls of gene activity; and the role of phosphorylated proteins as regulators of gene activity. The discussion then shifts to the phosphorylation state of non-histone proteins and its correlation with gene transcription; changes in nuclear proteins during embryonic development and cellular differentiation; and the manner by which histones are deposited onto replicating chromosomes. This book also explains the histone methylation, specific phosphorylation sites in lysine rich (H1) histone, and the separation and characterization of nuclear non-histone proteins by means of DNA columns. This book is of interest to advanced undergraduate students, as well as to graduate students and researchers in genetics, cell biology, molecular biology, biochemistry, and microbiology.
