The studies in this book demonstrated that increased oxidative stress in brain play a significant role in age-related cognitive impairment. Moreover, such increased oxidative stress leads to specific protein oxidation in the brain of cognitive impaired subject, thereby leading to cognitive function impairment. Moreover, the functional alterations of the proteins identified by proteomics in this book may leads to impaired metabolism, decline antioxidant system, and damaged synaptic communication. Ultimately, impairment of these processes lead to neuronal damages and cognitive decline. This book also show that several of the up- regulated and oxidized proteins in the brains of normal aging mice identified are known to be oxidized in neurodegenerative diseases as well, suggesting that the expression levels of certain proteins may increase as a compensatory response to oxidative stress. This compensation would allow for the maintenance of proper molecular functions in normal aging brains and protection against neurodegeneration.
People around the world are living longer. For the first time in history, most humans will live to be sixty and beyond. By 2050, the world's population aged 60 and over will reach a total of 2 billion, up from 900 million in 2015. Today, 125 million people are 80 years of age or older. By 2050, there will be 434 million people in this age group worldwide. In addition, the pace of aging of the world population is also increasing. However, there is not enough evidence to show that older people have better health than their parents. While rates of severe disability have declined over the past 30 years (but only in high-income countries), there have been no significant changes in mild to moderate disability over the same period of time. Indeed, the increase in the duration of life (lifespan) does not coincide with the increase in the duration of health (healthspan), that is, the period of life free from serious chronic diseases and disabilities. Therefore, the identification of the factors that predispose to a long and healthy life, as discussed in the papers of this book, is of enormous interest for translational medicine.
Have you ever done something so funny that you wanted to share this event with everyone? I have and I am. This book is about the events in my life and those around me and how, for some reason I'm still alive. In my short existance on this planet I have seen and done more than most people have done in a life time. And the party isn't over....you can bet that more of my life events will be printed for all to read. Life is short, enjoy your time on this wonderful and incredible place we call Earth.
Alzheimer’s disease (AD) is a chronic neurodegenerative disorder characterized by progressive cognitive dysfunction and memory loss, inability to perform the activities of daily living and mood disorders. According to the so-called “amyloid cascade hypothesis”, amyloid-ß- peptide (Aß), produced by beta- and gamma- secretase-mediated cleavages of the amyloid precursor protein (APP), plays a pivotal role in the pathogenesis of AD. Aß was also shown to contribute to AD pathology by stimulating the hyperphosphorylation of tau which is responsible for the formation of neurofibrillary tangles. However, the “amyloid cascade hypothesis” was challenged by other theories which lend suppor...
A consequence of rapid progress in the science of nutrigenomics and nutrigenetics is the substantial accumulation of data covering nutrienal modulation of gene expression at the cellular and subcellular levels. Current research is increasingly focused on the role of nutrition and diet in modifying oxidative damage in the progression of disease. Die
The 53rd National Congress of the Italian Society of Biochemistry and Molecular Biology (SIB), which will be held in Riccione from 23 to 26 September, is characterised by the elevated scientific level and interdisciplinary interest of the numerous sessions in which it is organised. The Scientific Programme comprises three joint Symposia of the SIB and the Chemistry of Biological Systems section of the Italian Chemistry Society (SCI) on Molecular Systems Biology, Chemistry of Nucleic Acids, Protein and Drug Structure, and Environmental Biotechnology. These Symposia address groundbreaking arguments, making the joint interest of the two societies particularly fascinating; the joint organisation...
