Available in PDF, EPUB and Kindle. Book excerpt: This book addresses chemical and biological aspects related to sesquiterpene lactones (STLs). Experts in different fields have been invited to contribute on this class of compound's chemistry, isolation and identification, biological activities (antibacterial, antifungal, antiviral, antitrypanosomal, antileishmanial,antiplasmodial, antiproliferative and antiinflammatory), synthesis, biosynthesis, derivatization and QSAR analysis. Taxonomic and chemotaxonomic aspects related to the Asteraceae family are also contributed. The book begins by describing the chemical characteristics of STLs, their classification in different skeleton types, synthesis, distribution in nature and their most important biological properties. An overview of the group's main representatives, based on their importance for human health, as well as an update of the most recently isolated STLs, follow. The authors also provide an overview of the most common methods described in the literature for the extraction, purification, identification and structure elucidation of STLs, while also highlighting more recently developed methods. Furthermore, experts in the field provide an in-depth discussion of the most commonly employed in vitro and in vivo antiprotozoal assays against the different stages of parasites, as well as STLs' properties as anticancer agents in numerous cancer cell lines and animal models. Lastly, the book presents examples of the in vitro and in vivo activity of STLs and their mechanism of antiprotozoal action, together with an analysis of ultrastructural alterations, observed using TEM techniques. The book is aimed at scientists working on natural products: both those investigating this particular group of compounds and those who wish to further explore its potential as new drugs for medical conditions such as protozoal diseases and cancer.
Download or read book Calcium Entry Channels in Non Excitable Cells written by Juliusz Ashot Kozak and published by CRC Press. This book was released on 2017-07-14 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calcium Entry Channels in Non-Excitable Cells focuses on methods of investigating the structure and function of non-voltage gated calcium channels. Each chapter presents important discoveries in calcium entry pathways, specifically dealing with the molecular identification of store-operated calcium channels which were reviewed by earlier volumes in the Methods in Signal Transduction series. Crystallographic and pharmacological approaches to the study of calcium channels of epithelial cells are also discussed. Calcium ion is a messenger in most cell types. Whereas voltage gated calcium channels have been studied extensively, the non-voltage gated calcium entry channel genes have only been identified relatively recently. The book will fill this important niche.

Download or read book Current Progress in the Understanding of Secondary Brain Damage from Trauma and Ischemia written by A. Baethmann and published by Springer Science & Business Media. This book was released on 1999-08-19 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information is provided from the basic and clinical sciences on the mechanisms damaging the brain from trauma or ischemia. New aspects involve the endoplasmic reticulum, mitochondrial failure, pathobiology of axonal injury, molecular signals activating glial elements, or the emerging therapeutical role of neurotrophins. Experimental issues involve a better analysis of the ischemic penumbra, the salvagable tissue. Therapeutic contributions reach from the environmental influence to gene expression, including neuroprotection, such as hibernation - mother nature's experiment - or hypothermia which is reported to induce cell swelling. Treatment issues deal also with thrombolysis and combination therapies, or with the clearance of adverse blood components - LDL/fibrinogen - by a novel procedure using heparin. Other highlights are discussing the specificities of pediatric vs. adult brain trauma, or the evolving role of the Apolipoprotein-E e4 gene in severe head injury. An update is also provided on an online assessment of the patient management during the pre- and early hospital phase in Southern Bavaria. The empirical observation of neuroworsening is analyzed in further details, whether this is a specificity autonomously driving the posttraumatic course. Finally, the unsolved question why drug trials in severe head injury have failed so far in view of the promising evidence from the laboratory is subjected to an expert analysis.

Download or read book The Endothelium written by Michel Félétou and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells. The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation of immunology, inflammation and angiogenesis, and an important metabolizing and an endocrine organ. Endothelial cells controls vascular tone, and thereby blood flow, by synthesizing and releasing relaxing and contracting factors such as nitric oxide, metabolites of arachidonic acid via the cyclooxygenases, lipoxygenases and cytochrome P450 pathways, various peptides (endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine, purines, reactive oxygen species and so on. Additionally, endothelial ectoenzymes are required steps in the generation of vasoactive hormones such as angiotensin II. An endothelial dysfunction linked to an imbalance in the synthesis and/or the release of these various endothelial factors may explain the initiation of cardiovascular pathologies (from hypertension to atherosclerosis) or their development and perpetuation.

Download or read book Magnesium in the Central Nervous System written by Robert Vink and published by University of Adelaide Press. This book was released on 2011 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.

Download or read book Metallo Drugs Development and Action of Anticancer Agents written by Astrid Sigel and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-02-05 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 18, entitled Metallo-Drugs: Development and Action of Anticancer Agents of the series Metal Ions in Life Sciences centers on biological, medicinal inorganic chemistry. The serendipitous discovery of the antitumor activity of cis-diamminodichloroplatinum(II) (cisplatin) by Barnett Rosenberg in the 1960s is a landmark in metallodrug-based chemotherapy. The success of cisplatin in the clinic, followed by oxaliplatin and carboplatin, along with their drawbacks relating mainly to resistance development and severe toxicity, initiated research on polynuclear platinum complexes and on Pt(IV) complexes as prodrugs. Furthermore, the indicated shortcomings led to the exploration of other transition and main group metal ions, among them Ru(II/III), Au(I/III), Ti(IV), V(IV/V), and Ga(III) including also the essential metal ions Fe(II/III), Cu(I/II), and Zn(II). Ionic as well as covalent and non-covalent interactions between structurally very different complexes and biomolecules like nucleic acids, proteins, and carbohydrates are studied and discussed with regard to their possible anticancer actions. Hence, MILS-18 summarizes the research at the forefront of medicinal inorganic chemistry, including studies on the next-generation, tailor-made anticancer drugs. All this and more is treated in an authoritative and timely manner in the 17 stimulating chapters of this book, written by 39 internationally recognized experts from 10 nations (from the US via Europe to China and Australia). The impact of this vibrant research area is manifested by more than 2700 references, nearly 150 illustrations (more than half in color) and several comprehensive tables. Metallo-Drugs: Development and Action of Anticancer Agents is an essential resource for scientists working in the wide range from enzymology, material sciences, analytical, organic, and inorganic biochemistry all the way through to medicine including the clinic ... not forgetting that it also provides excellent information for teaching.
