    Marijuana and Health Hazards: Methodological Issues in Current Research is a collection of manuscripts presented at a conference on methodological issues involving marijuana research, held in Washington, D.C., sponsored by the Drug Abuse Council Inc. This book is composed of five parts encompassing 18 chapters that focus on the human health consequences of marijuana consumption. Part I discusses the cytogenetic effects of marijuana, with an emphasis on its cell-damaging, genotoxic, and teratogenic effects. Part II describes the interaction of marijuana products on the T-lymphocytes of man and Part III examines the effects of marijuana smoking on male reproduction, specifically on plasma testosterone level. Part IV investigates the central nervous system damage associated with marijuana use and looks into some of the methodological problems arising at the general issues of central nervous system dysfunction as these relate to marijuana consumption. Part V focuses on the psychiatric consequences of different degrees of marijuana use. This book is of great benefit to scientists and researchers who wish to elucidate the issues regarding the effects of marijuana.

  • Genetics and Biotechnology of Bacilli, Volume 2

    • 1st Edition
    • A.T. Ganesan
    • English
    Genetics and Biotechnology of Bacilli, Volume 2 is a collection of papers from the "Fourth International Conference on Bacilli" held in California on June 21-24, 1987. One paper reviews the results of cloning and characterization of genes for secreted enzyme and of genes that control the expression of secreted enzymes in relation with other prokaryotic regulatory systems. Other papers tackle the regulation of gene expression during sporulation, the sigma factors, bacterial toxins, and antibiotic resistance genes. One paper reports that three genes responsible for the code for peptides found in BT cuboidal crystals have been successfully cloned. The three codes have different toxic characteristics in relation to tobacco hornworm larvae or mosquito larvae. Other papers examine replication. Such examination pertains to the two levels of control on the chromosome involved in DNA replication, or to the possible functional importance that several membranes associated DNA subcomplexes can have in Bacillus subtilis, where one of these appear to control initiation. Other papers discus secretion and extracellular enzymes, as well as, the different genetic systems and methods. This collection can prove beneficial for biochemists, micro-biologists, cellular researchers, and academicians involved in the study of cellular biology, microchemistry, or toxicology.

    • David Greenberg
    • English
    Metabolic Pathways, Third Edition: Volume IV: Nucleic Acids, Protein Synthesis, and Coenzymes focuses on the metabolic pathways of the major biological constituents of living organisms, namely, nucleic acids, proteins, and coenzymes. The biosynthesis and metabolism of purines and pyrimidines, nucleotides, riboflavin and related compounds, and vitamin B6 are discussed. The biogenesis and metabolism of thiamine and folic acid are also considered. This volume is comprised of seven chapters and begins with an analysis of metabolic control and enzymology of purines and pyrimidines such as inosinic acid and nucleotides. The next chapter is devoted to the biosynthesis and metabolism of nucleotides and nucleic acids, making reference to deoxyribonucleotides as well as RNA and DNA. Some of the reactions involving nucleotides are classified and briefly discussed. The reader is then introduced to protein synthesis, paying particular attention to the chemical features of the synthesis of the peptide bond and the characteristics of the genetic code implicated in this process. The remaining chapters focus on riboflavin and related compounds, thiamine, folic acid, and vitamin B6. This book will be a useful resource for biochemists and biologists.

  • Psychopharmacological Agents V4

    • 1st Edition
    • Maxwell Gordon
    • English
    Psychopharmacologica... Agents, Volume IV summarizes the chemistry, pharmacology, and clinical manifestations of psychoactive drugs which are abused, with emphasis on opiate abuse and its treatment. The historical, legal, regulatory, and sociological aspects of the abuse of central nervous system agents are described, along with the treatment modalities that have evolved from some of these afflictions. Comprised of six chapters, this volume begins with an introduction to drug abuse and drug dependence, followed by a discussion on various perspectives in drug abuse and modalities for treating patients who are dependent on opiates. Studies on non-abusive analgetics such as opium compounds are then reviewed, together with the chemistry, mechanism of action, and medical applications of psychotomimetic drugs. The final two chapters deal with the treatment of opiate abuse by methadone maintenance and the regulatory aspects of drug abuse.

  • Biology of Hydra

    • 1st Edition
    • Allson Burnett
    • English
    Biology of Hydra covers eight areas of Hydra biology, particularly, its behavior and ecology; polarity; gastrodermal and epidermal regeneration; differentiation of nervous elements; cell proliferation and morphogenesis; and mesoglea. This book describes, in particular, the various aspects of Hydra's behavior, not obvious in casual observation, as well as the animal’s feeding and digestion. It also looks into the contribution of interstitial cells to the regenerative process in Hydra; the ultrastructural changes during dedifferentiation and redifferentiation in the regenerating, isolated gastrodermis; regeneration from isolated epidermal explants; and regeneration of a Hydra containing no interstitial cells from an isolated basal disc. Furthermore, the book explains the grafting of the gastrodermis of Hydra viridis to the epidermis of Hydra pseudoligactis, and the results of such agraft on two animals sectioned for histological study. It examines the role of the neoblast in regeneration and the ultrastructure of Hydra’s nervous system. The book also explores Hydra’s growth and the contribution of cell proliferation to net growth and maintenance of form.
