This book was released on 2009 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current approaches to treat neurodegenerative disease provide only mild symptomatic relief but do not modify the natural history of these conditions. A large body of evidence suggests that mitochondrial dysfunction is a key event in the pathophysiology of neurodegeneration. Supporting and improving mitochondrial function has a big potential as a strategy for neuroprotection. The goal of this dissertation was to test whether interventions that target mitochondrial function are effective at preventing neurodegeneration induced by mitochondrial failure in vivo. A rodent model of optic neuropathy induced by the mitochondrial toxin rotenone was used to test the neuroprotective effects of methylene blue (MB) and near-infrared light (NIL), two interventions with mechanisms of action localized to mitochondria. This work also tested the effects of memantine, an NMDA receptor blocker, to further characterize the relationship between excitotoxicity and mitochondrial dysfunction. Neuroprotective effects were evaluated via behavioral testing of visual function and histopathological analysis of the retina. The neurochemical effects of MB, NIL and memantine were analyzed in vitro and in vivo with indicators of oxidative stress, cell respiration and catalytic activity of respiratory enzymes, including NADH dehydrogenase and cytochrome oxidase. MB, a diaminophenothiazine with potent antioxidant and unique redox properties, prevented the changes in visual function and the retinal histopathology induced by rotenone. In vitro, MB increased oxygen consumption and prevented the increases in oxidative stress in brain tissue induced by rotenone. NIL prevented the behavioral impairment and the decrease in retinal and visual pathway metabolic activity, retinal nerve fiber layer thickness and ganglion cell layer cell density induced by rotenone in a dose-dependent manner. Whole-brain cytochrome oxidase and superoxide dismutase activities were also increased in NIL-treated subjects in a dose-dependent manner, suggesting an in vivo transcranial effect of NIL. Finally, uncompetitive NMDA receptor blockade with memantine displayed neuroprotection against rotenone-induced neurodegeneration in a dose-response manner, and this effect was associated with a decrease in retinal oxidative stress and a long-term increase in neuronal energy metabolism capacity. These data constitute a proof-of-principle that interventions that target the mitochondria and support the function of the respiratory chain are effective at preventing neurodegeneration in vivo.

Book Synopsis Magnesium in the Central Nervous System by : Robert Vink
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.

Book Synopsis Drug Discovery and Evaluation: Methods in Clinical Pharmacology by : H.Gerhard Vogel
Download or read book Drug Discovery and Evaluation: Methods in Clinical Pharmacology written by H.Gerhard Vogel and published by Springer Science & Business Media. This book was released on 2010-12-15 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drug Discovery and Evaluation has become a more and more difficult, expensive and time-consuming process. The effect of a new compound has to be detected by in vitro and in vivo methods of pharmacology. The activity spectrum and the potency compared to existing drugs have to be determined. As these processes can be divided up stepwise we have designed a book series "Drug Discovery and Evaluation" in the form of a recommendation document. The methods to detect drug targets are described in the first volume of this series "Pharmacological Assays" comprising classical methods as well as new technologies. Before going to man, the most suitable compound has to be selected by pharmacokinetic studies and experiments in toxicology. These preclinical methods are described in the second volume „Safety and Pharmacokinetic Assays". Only then are first studies in human beings allowed. Special rules are established for Phase I studies. Clinical pharmacokinetics are performed in parallel with human studies on tolerability and therapeutic effects. Special studies according to various populations and different therapeutic indications are necessary. These items are covered in the third volume: „Methods in Clinical Pharmacology".
