This book was released on 2011 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alzheimer's disease (AD) represents a growing biomedical, social, and economical problem. Millions of people have suffered from the disease globally. Studies have shown that aggregated forms of amyloid [beta] peptide adversely affect neuronal function and may represent the causative agent in AD. It has been demonstrated that chronic treatment with ibuprofen and naproxen reduces the risk of AD and improves the behavioral impairment for patients with AD. This dissertation utilizes high performance parallel computing, all-atom molecular dynamics simulation, and protein-ligand docking to understand the mechanism of the anti-aggregation effect of ibuprofen and naproxen in Alzheimer's amyloidogenesis. The results reveal different mechanisms of ligand binding to the monomers and fibrils formed by A[beta] peptides implicated in AD. Binding to A[beta] monomers is mostly governed by ligand-amino acid interactions, whereas binding to the fibril is determined by the fibril surface geometry and interligand interactions. The antiaggregation effect of ibuprofen and naproxen is explained by direct competition between these ligands and incoming A[beta] peptides for binding to the fibril.

This book was released on 2002 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Alzheimer's disease (AD) is a neurological disorder characterized by plaque deposition and an elevated immune response. Epidemiological studies have shown that use of non-steroidal anti-inflammatory drugs (NSAIDs) by the elderly is associated with a decreased relative risk and a delayed onset of AD. Moreover, the apolipoprotein E (apoE) gene has been proven to be a risk factor for AD with apoE &egr;4 AD patients having been found to show lower levels of brain apoE. In the present study, treatment of primary rat mixed glial cell cultures with indomethacin, aspirin, and interleukin-1beta resulted in significant increases in extracellular apoE protein. Furthermore, treatment of primary rat astrocyte cell cultures with aspirin, interleukin-6, and a cyclooxygenase-2 selective aspirin derivative was found to result in increased levels of apoE. Consequently, NSAID-induced increases in apoE protein may enhance apoE-mediated immunosuppression and compensatory synaptic plasticity, potentially resulting in decreased risk and delay of disease onset." --

This book was released on 2010 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: For many years, it has been known that Rheumatoid arthritis (RA) is a negative risk factor for the development of Alzheimer's disease (AD). It has been commonly assumed that RA patients' usage of non-steroidal anti-inflammatory drugs (NSAIDs) have helped prevent the onset and progression of AD pathogenesis. Furthermore, experiments in animal models of Alzheimer's disease have looked to inhibit inflammation, and have demonstrated some efficacy against AD-like pathology in these models. Thus many NSAID clinical trials have been performed over the years, but all have proven unsuccessful in AD patients. This suggested that intrinsic factors within RA pathogenesis itself may underlie RA's protective effect. My dissertation research goal was to investigate this inverse relationship between RA and AD, in order to more precisely pinpoint critical events in AD pathogenesis toward developing therapeutic strategies against AD. It seemed improbable that any secreted factors, produced in RA pathogenesis, could maintain high enough concentrations in the circulatory system to cross the blood brain barrier and inhibit AD pathogenesis, without affecting all other organ systems. It did seem possible that the leukocyte populations induced in RA, could traverse the circulatory system, extravasate into the brain parenchyma, and impede or reverse AD pathogenesis. We thus investigated the colony-stimulating factors, which are up-regulated in RA and which induce most of RA's leukocytosis, on the pathology and behavior of transgenic AD mice. We found that G-CSF and more significantly, GM-CSF, reduced amyloidosis throughout the treated brain hemisphere one week following bolus intrahippocampal administration into AD mice. We then found that 20 days of subcutaneous injections of GM-CSF (the most amyloid-reducing CSF in the bolus experiment) significantly reduced brain amyloidosis and completely reversed cognitive impairment in aged cognitively-impaired AD mice, while increasing hippocampal synaptic area and microglial density. These findings, along with two decades of accrued safety data using Leukine, the recombinant human GM-CSF analogue, in elderly leukopenic patients, suggested that Leukine should be tested as a treatment to reverse cerebral amyloid pathology and cognitive impairment in AD patients. It was also implied that age-related depressed hematopoiesis may be etiological for AD pathogenesis.

Available in PDF, EPUB and Kindle. Book excerpt: Neurodegenerative diseases, including Alzheimer’s, Parkinson’s, Huntington’s, and amyotrophic lateral sclerosis, are the most common pathologies of the central nervous system currently without a cure. They share common molecular and cellular characteristics, including protein misfolding, mitochondrial dysfunction, glutamate toxicity, dysregulation of calcium homeostasis, oxidative stress, inflammation, and ageing, which contribute to neuronal death. Efforts to treat these diseases are often limited by their multifactorial etiology. Natural products, thanks to their multitarget activities, are considered promising alternatives for the treatment of neurodegeneration. This book deals with two different forms of natural products: extracts and isolated compounds. The study of the bioactivity of the extracts is extremely important as many studies have demonstrated the synergistic effect of the combination of different natural products. On the other hand, the investigation of the activity of specifically isolated natural products can be also important to understand their cellular and molecular mechanisms and to define the specific bioactive components in extracts or foods. This book can be considered an important contribution to knowledge of the neuroprotective effect of natural products and presents a great deal of information, related to both the benefits but also the limitations of their use in counteracting neurodegeneration.

Download or read book Epigenetics of Aging written by Trygve O. Tollefsbol and published by Springer Science & Business Media. This book was released on 2009-11-11 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies have indicated that epigenetic processes may play a major role in both cellular and organismal aging. These epigenetic processes include not only DNA methylation and histone modifications, but also extend to many other epigenetic mediators such as the polycomb group proteins, chromosomal position effects, and noncoding RNA. The topics of this book range from fundamental changes in DNA methylation in aging to the most recent research on intervention into epigenetic modifications to modulate the aging process. The major topics of epigenetics and aging covered in this book are: 1) DNA methylation and histone modifications in aging; 2) Other epigenetic processes and aging; 3) Impact of epigenetics on aging; 4) Epigenetics of age-related diseases; 5) Epigenetic interventions and aging: and 6) Future directions in epigenetic aging research. The most studied of epigenetic processes, DNA methylation, has been associated with cellular aging and aging of organisms for many years. It is now apparent that both global and gene-specific alterations occur not only in DNA methylation during aging, but also in several histone alterations. Many epigenetic alterations can have an impact on aging processes such as stem cell aging, control of telomerase, modifications of telomeres, and epigenetic drift can impact the aging process as evident in the recent studies of aging monozygotic twins. Numerous age-related diseases are affected by epigenetic mechanisms. For example, recent studies have shown that DNA methylation is altered in Alzheimer’s disease and autoimmunity. Other prevalent diseases that have been associated with age-related epigenetic changes include cancer and diabetes. Paternal age and epigenetic changes appear to have an effect on schizophrenia and epigenetic silencing has been associated with several of the progeroid syndromes of premature aging. Moreover, the impact of dietary or drug intervention into epigenetic processes as they affect normal aging or age-related diseases is becoming increasingly feasible.
