The last two decades have seen a number of significant advances in the methodology for evaluating the molecular weight distributions of polydispersed macromolecular systems in solution at the molecular level. This reference presents reviews on the progress in different analytical and characterization methods of biopolymers. Readers will find useful information about combinations of complex biopolymer analysis such as chromatographic or membrane based fractionation procedures combined with multiple detectors on line (multi-angle laser light scattering or MALLS). Key topics include: • refractive index, UV-Vis absorbance and intrinsic viscosity detection systems, • advances in SEC-MALLS (size exclusion chromatography coupled to multi-angle laser light scattering) and FFF-MALLS (field flow fractionation coupled on line to MALLS), • HPSEC-A4F-MALLS, matrix-assisted laser-desorption ionization (MALDI) • electrospray ionization (ESI) mass spectrometry • nuclear magnetic resonance (NMR) spectroscopy This reference is intended for students of applied chemistry and biochemistry who require information about biopolymer analysis and characterization.

β-Glucan is generally considered to be a very safe immunomodulator. It is a well-known biological response modifier (BRM) that has been used as an adjuvant therapy for cancer since 1980, mostly in Japan. β-Glucan enhances the innate host defense against certain bacteria, yeast, and viral pathogens. I addition, glucans are also considered to be important in prophylaxis against irradiation. Various types of glucans are now routinely added both to human and animal food. At least 26 clinical trials are currently under way in several countries. The authors of this ebook have selected and brought together information on both theoretical and practical aspects of β-glucan use. The book is suitable for readers seeking timely and precise information on β-glucan history and various biological effects including possible use in the treatment of various diseases, without having any preliminary knowledge of natural immunomodulators. The book should not only provide an inspiration for carbohydrate and clinical chemists for further investigations in biomedicine, but it also presents a number of practical applicable results in immunology

Poisons, due to their lethal nature, invoke a sense of fear in humans. Yet, they have also impacted other aspects of human life. Poisons have been used by nomadic hunters to kill their prey, by scientists to explore complex biochemical mechanisms of the body, by physicians to lower cholesterol and to kill cancer cells, by farmers and the general public to destroy pests, by the evil minded for homicide, and by tyrants as weapons of war. The Art and Science of Poisons presents two facets of poisons: the science behind them and their place in history and art. The science of poisons describes their biochemistry and how they kill. The science story voyages into the sub-microscopic world of atoms, molecules, and cells. Only there can we see the true miracles and mysteries of life and death. Chapters in the book explore poisons from snakes, spiders, scorpions, sea creatures, as well as poisons made by humans in the laboratory, and those which are derived from beautiful plants. The art of poisons, on the other hand, encompasses everything else about these agents that conjures up the image of the skull and crossbones. This side of the story explores the legends and tales of intrigue and surreptitious deaths of well-known personalities such as Socrates, Cleopatra, Hitler, and many more. General readers with a curiosity about science and an interest in history and human nature will enjoy both facets presented in this brief, yet varied exploration into the world of poisons.

The interactions between carbohydrates and proteins have been extensively explored in a wide range of physiological and pathological processes over several decades. The recent emergence of glycomics has strengthened this interest and notably contributed to spectacular progress in understanding how carbohydrates mediate and regulate complex biological events. Synthesis and Biological Applications of Glycoconjugates gives a summary of contemporary findings in glycoconjugate research. Readers will be updated on major achievements in chemical methods and biological applications employed in modern glycomics. The Ebook should be of interest to a broad community of students and professional researchers in both academia and industry.

Bentham Briefs in Biomedicine and Pharmacotherapy brings new trends and techniques in pharmacology and medical biochemistry to the forefront through unique volumes. Each volume provides a brief review of selected topics, written by scientific experts. The book series is essential reading for graduate students and researchers in pharmacology and life sciences as well as medical professionals seeking knowledge for research oriented projects. The first volume, Oxidative Stress and Natural Antioxidants, is a compilation of articles about free radicals (which are extremely reactive, short-lived molecules with unpaired electron valency), and antioxidants (which are stabilizing agents of free radicals in the body). The volume presents 17 chapters on the biochemistry of free radicals and antioxidants, with contributions from over 60 scientists. Readers will understand the basic and clinical aspects of free radical biomedicine, the role of antioxidants in neutralizing free radicals through physiological homeostasis, as well as the range of natural compounds which can be used to combat oxidative stress. The chapters also cover special topics such as recent advances in preparation methods of antioxidants, and industrial applications of antioxidants. The range of topics in this volume provide a consolidated reference for a broad set of readers on the subject.

Aluminium is a chemical element present in earth’s crust and it is a known environmental toxin which has been found to be associated with various neurological disorders. Aluminium has been found to be a very strong risk factor for the development of Alzheimer’s disease. Biochemical Mechanisms of Aluminium Induced Neurological Disorders explains the association of aluminium with neurological disorders. The book introduces the reader to sources of aluminium exposure, followed by an explanation of pharmacokinetics of aluminium and the different biochemical pathways that cause neurological effects. Chapters cover the typical mechanisms associated with aluminium neurotoxicity such as synaptic impairment as well as recent topics of interest such as the role of aluminum in impairing blood-brain barrier functions.

Organotins are widespread contaminants especially of water environments. Their chemically versatile structure makes organotin compounds able to bind to a variety of biomolecules thus widely affecting biological functions. Trisubstituted molecules, namely tributyltin (TBT) and triphenyltin (TPhT), have been widely employed in antifouling paints and are also exploited as plastic stabilizers that unfortunately cause harmful biological effects. Persistent bioaccumulation has resulted in organotins becoming a significant environmental threat. Chapter by chapter, the biological and biochemical effects of organotins are unravelled in this e-book by a careful analysis of the most recent findings with special focus on contaminant action mechanisms at cellular and molecular level. The e-book provides an intriguing insight into the molecular mechanisms involved in organotin toxicology thus serving as a useful reference to biochemists, biologists, ecotoxicologists and life science students.
