Free radicals are atoms or molecules containing unpaired electrons. Damage occurs when the free radical encounters another molecule and seeks to find another electron to pair its unpaired electron. Free radicals can cause mutation in different biological compounds such as protein, nucleic acids, and lipids, and the damage caused by the free radicals lead to various diseases (cancer, cardiovascular disease, aging, etc.). Antioxidants are helpful in reducing and preventing damage from free radical reactions because of their ability to donate electrons, which neutralize the radical without forming another. Ascorbic acid, for example, can lose an electron to a free radical and remain stable itse...
Marine organisms have been under research for the last decades as a source for different active compounds with various biological activities and application in agriculture, pharmacy, medicine, environment, and industries. Marine polysaccharides from these active compounds are used as antibacterial, antiviral, antioxidant, anti-inflammation, bioremediations, etc. During the last three decades, several important factors that control the production of phytoplankton polysaccharides have been identified such as chemical concentrations, temperature, light, etc. The current book includes 14 chapters contributed by experts around the world; the chapters are categorized into three sections: Marine Polysaccharides and Agriculture, Marine Polysaccharides and Biological Activities, and Marine Polysaccharides and Industries.
This book offers reviews of state-of-the-art conversion techniques for biofuels. It focuses on the latest development for the production of liquid and gaseous biofuels that should be of interest to the chemical scientists and technologists.
Antioxidants are substances that can prevent or slow damage to living cells caused by free radicals, which are unstable molecules the body produces as a reaction to environmental and other pressures. Sometimes called “free-radical scavengers,” free radicals can cause mutation in different biological compounds such as protein, nucleic acids, and lipids, which lead to various diseases (cancer, cardiovascular disease, aging, etc.). Healthy foods are considered a main source of antioxidant compounds and from the beginning of a person’s life, a strong relationship is seen between antioxidant compounds and the prevention of certain diseases, such as types of inflammations, cardiovascular diseases, and different kinds of cancers. It is thus of great importance that new data relating to antioxidants and their biological activity be collected and that antioxidant modes of action be illustrated.Experts from around the world contributed to the current book, discussing antioxidant sources, modes of action, and their relation to human diseases. Twenty-five chapters are presented in two sections: Antioxidants: Sources and Modes of Action and Antioxidants Compounds and Diseases.
This book introduces a novel approach to comprehending and assessing oxidative stress and antioxidant activity as fundamental components in both health and disease. It explores the advantages and peculiarities of innovative electrochemical methods for estimating and monitoring these processes. Recognizing the electrochemical nature of oxidative stress, the book advocates for electrochemical methods as the preferred means of determination. A central focus of the book is the presentation of a new electrochemical method for evaluating oxidative stress and antioxidant activity: potentiometric determination. The book presents results of antioxidant activity analyses for both healthy individuals a...
Food and Lifestyle in Health and Disease gathers information on various food types providing an explanation of their nutrient composition, sources, roles, and mechanisms in health and diseases. To obtain good health practices and prevent diseases, it is necessary to understand links in the relationship of food, lifestyle, environment, and health. This book is a vital source for research topics related to these issues, including the following: Analysis of various types of food and lifestyles for the prevention and treatment of diseases and disorders, including cardiovascular disorders, cancers, neurodegenerative diseases, diabetes, hypertension, and obesity. The influences of environmental pollution, synergistic effects of different foods, and synergy of foods with physical activity or medicine. The roles of animal, fungal, and plant source foods in human health and disease. This book is appropriate for health-conscious users, health care providers and practitioners, teachers, and researchers.
Public Health and Preventive Medicine is a textbook intended for students of general medicine and dentistry, but it can also be used by healthcare professionals. The aim of the book is to provide information on preventive activities that can prolong life expectancy and improve the quality of life of individuals and populations. The book contains an overview of main topics of the public health and the interactions between health and the environment with an emphasis on influenceable lifestyle factors in the prevention of chronic non-communicable diseases.
The edited volume presents the progress of first and second generation biofuel production technology in selected countries. Possibility of producing alternative fuels containing biocomponents and selected research methods of biofuels exploitation characteristics (also aviation fuels) was characterized. The book shows also some aspects of the environmental impact of the production and biofuels using, and describes perspectives of biofuel production technology development. It provides the review of biorefinery processes with a particular focus on pretreatment methods of selected primary and secondary raw materials. The discussion includes also a possibility of sustainable development of presented advanced biorefinery processes.
