Biochimie médicale
Directement orienté vers les pathologies ou les dysfonctionnements d'organes à cibler, ce livre est un véritable guide pratique des marqueurs biochimiques organisé en deux parties. Les premiers chapitres sont essentiellement de nature méthodologique et décrivent les différents outils spécialisés et innovants à la disposition du biologiste qui souhaite: connaître le principe et les performances de la ou des méthodologies analytiques disponibles, mettre au point le dosage d'une nouvelle molécule lorsqu'il dispose d'un système ouvert. Les chapitres de la deuxième partie déterminent la place des marqueurs dans des contextes pathologiques donnés. Chaque marqueur est décrit selon...
Plant Derived Bioactive Compounds in Human Health and Disease
This book offers a comprehensive review of the multifaceted role of phytochemicals in promoting human health and combating diseases. The initial chapters introduce phytochemicals, navigate the natural health landscape, and provide a foundational understanding of these bioactive compounds. The book unfolds the role of phytochemicals as a formidable defense against oxidative stress and explores the unique health benefits and nutritional significance of phytochemicals found in fruit peels. The subsequent chapters further discuss the therapeutic potential of phytochemicals, detailing their role in combating multidrug-resistant bacterial infections and modulating critical pathways in inflammation...
Frontiers in Antioxidants Research
In biological systems, the normal processes of oxidation (plus a minor contribution from ionising radiation) produce highly reactive free radicals. These can readily react with and damage other molecules. In some cases the body uses free radicals to destroy foreign or unwanted objects, such as in an infection. However, in the wrong place, the body's own cells may become damaged. Should the damage occur to DNA, the result could be cancer. Antioxidants decrease the damage done to cells by reducing oxidants before they can damage the cell. Virtually all studies of mammals have concluded that a restricted calorie diet extends the life span of mammals by as much as 100%. This remarkable finding s...
Impact of Lipid Peroxidation on the Physiology and Pathophysiology of Cell Membranes
The general process of lipid peroxidation consists of three stages: initiation, propagation, and termination. The initiation phase of lipid peroxidation includes hydrogen atom abstraction. Several species can abstract the first hydrogen atom and include the radicals: hydroxyl, alkoxyl, peroxyl, and possibly HO* 2. The membrane lipids, mainly phospholipids, containing polyunsaturated fatty acids are predominantly susceptible to peroxidation because abstraction from a methylene group of a hydrogen atom, which contains only one electron, leaves at the back an unpaired electron on the carbon. The initial reaction of *OH with polyunsaturated fatty acids produces a lipid radical (L*), which in tur...
Oxygen Radicals in Biological Systems, Part C
Since biological tissues are unstable in an oxygen atmosphere, a great deal of effort is expended by organisms to metabolically limit or repair oxidative tissue damage. This volume of Methods in Enzymology and its companion Volume 234 present methods developed to investigate the roles of oxygen radicals and antioxidants in disease. Key Features * Generation, detection, and characterization of oxygen radicals, chemistry, biochemistry, and intermediate states of reductio* Isolation, characterization, and assay of enzymes or substrates involved in formation or removal of oxygen radical * Methods for assessing molecular, cell, and tissue damage; assays and repair of oxidative damage
NeuroPhytomedicine
Neurological disorders categorized as neurodegenerative, neuropsychiatric, and neurotraumatic impose a substantial health burden and cause a frail impact on life attributes. The use of synthetic drugs can have undesirable side effects, making neurotherapeutics challenging. Research on neuroprotection aiming for the utilization of safer natural compounds; phytochemicals specifically – is a cutting-edge approach. NeuroPhytomedicine intends to present readers with a wide-ranging and state-of-the-art appearance at the beneficial properties of phytochemicals on various neurological ailments. It additionally contains sections explaining: • Applications of phyto-nanotechnology in neurological ailments, • Phytoconstituents related deep learning and machine learning-based solutions for neurological disorders, • Epigenetic relevance pertaining to modulation by phytochemicals. The goal of NeuroPhytomedicine is to give readers a thorough and up-to-date look at how phytochemicals affect the brain and neurological illnesses in a way that is helpful for research scholars, academicians, scientists, neuroscientists, physicians, and researchers from the pharmaceutical industry.
Redox-Genome Interactions in Health and Disease
At the nexus of advances in molecular genetics and findings in redox biology, this volume elaborates on the dynamics governing cellular redox states and aggregates the body of evidence linking oxidative stress and redox modulation with a host of monogenetic and polygenetic diseases.
Radicaux libres et stress oxydant: Aspects biologiques et pathologiques ( broché)
Radicaux libres et stress oxydant, ouvrage sans précédent en français, aborde la problématique du stress oxydant dans son intégralité, depuis la chimie du radical libre jusqu'à la description de son rôle dans la physiopathologie des maladies chroniques. Les développements très détaillés de l'ouvrage s'articulent en deux parties. La première fait le point des connaissances concernant la physicochimie des espèces réactives de l'oxygène et de l'azote, envisageant leurs sources cellulaires, leurs principaux effets biologiques et les dommages qu'elles créent aux biomolécules. Les caractéristiques des antioxydants d'origine endogène et exogène (liés aux apports nutritionnels)...
