Resumen

ZusammenfassungDie Atherosklerose und ihre wichtigsten Komplikationen – Myokardinfarkt und Schlaganfall – sind die Hauptursachen für Tod und Behinderung in den USA und weltweit. Eine dramatische Zunahme bei Adipositas und Diabetes mellitus wird wahrscheinlich auch in Zukunft zu einer hohen Prävalenz kardiovaskulärer Erkrankungen (CVD) und deren Auswirkungen auf das Gesundheitswesen führen. Große Fortschritte gibt es bei der Entwicklung neuer Therapien zur Senkung der Inzidenz von Atherosklerose und CVD, besonders bei der Behandlung der Hypercholesterinämie und Hypertonie.

Resumen

Avital component of cellular redox equilibrium, mitochondria also play a crucial role in the synthesis of energy within cells. Disturbances in the metabolism of carbon inside the mitochondria may cause malfunction and oxidative stress, which in turn may contribute to the etiology of a number of human diseases. This is supported by newly emerging research. The interaction of oxidative stress and mitochondrial carbon stress is examined in this review, with particular attention on how these effects affect human health. We go over the processes that underlie oxidative stress caused by mitochondria

Resumen

Obesity is a disease of excessive accumulation of adipose tissue due to an increased energy intake which is disproportionate to the energy expenditure in the body. The visceral adipose tissue in the obese accumulated in that way increases the risk of developing a number of metabolic and cardiovascular diseases. Disorders such as diabetes, dyslipidemia, inflammation, endothelial dysfunction and mitochondria can contribute to the development of oxidative stress, which is especially pronounced in the abdominal type of obesity. Obesity can induce systemic oxidative stress through a variety of bioc

Resumen

One of the main causes of blindness is the multifactorial condition known as cataract. It is believed that oxidative stress plays a significant role in starting the cataractogenesis process. Today, it is a well-established fact that oxidative stress plays a role in both diabetes-induced cataract (diabetic) and age-related cataract (senile). The most likely cause of oxidative damage to the lens is a compromised antioxidant defense system brought on by age and diabetes-related increases in reactive oxygen species (ROS) production. The main factor contributing to cataract formation is systemic ox

Resumen

Schönfeld and Reiser recently hypothesized that fatty acid β-oxidation is a source of oxidative stress in the brain. To test this hypothesis, we inhibited brain mitochondrial β-oxidation with methyl palmoxirate (MEP) and measured oxidative polyunsaturated fatty acid (PUFA) metabolites in the rat brain. Upon MEP treatment, levels of several nonenzymatic auto-oxidative PUFA metabolites were reduced with few effects on enzymatically derived metabolites. Our finding confirms the hypothesis that reduced fatty acid β-oxidation decreases oxidative stress in the brain and β-oxidation inhibitors may be

Resumen

The unceasing need for oxygen is in contradiction to the fact that it is in fact toxic to mammals. Namely, its monovalent reduction can have as a consequence the production of short-living, chemically very active free radicals and certain non-radical agents (nitrogen-oxide, superoxide-anion-radicals, hydroxyl radicals, peroxyl radicals, singlet oxygen, peroxynitrite, hydrogen peroxide, hypochlorous acid, and others). There is no doubt that they have numerous positive roles, but when their production is stepped up to such an extent that the organism cannot eliminate them with its antioxidants (

Resumen

The process of cell damage resulting from the action of free radicals – reactive oxygen species (ROS) – is called oxidative stress. Most ROS are constantly formed in the cell – about 5 % of the oxygen consumed by tissues is converted into free radicals, but their level is normally so small that the cell inactivates them with the help of an antioxidant system. Different organs and tissues are exposed to different degrees of ROS and demonstrate different stability during the implementation of oxidative stress. The mechanisms of ROS formation by mitochondria under oxidative stress are still uncle

Oxidative stress refers to the dramatic increase in the production of free radicals in human and animal bodies or the decrease in the ability to scavenging free radicals, thus breaking the antioxidation–oxidation balance. Various factors can induce oxidative stress in pig production.

Oxidative stress (OS) is a redox homeostasis disorder that results in oxidation of cell components and thus disturbs cell metabolism. OS is induced by numerous internal as well as external factors.

We reviewed literature available in PubMed, Medline, and Scopus databases, including the results from 2010 to 2020. Publications were searched according to the keywords: oxidative stress and dental monomers; oxidative stress

Resumen

Traumatic stress may chronically affect master homeostatic systems at the crossroads of peripheral and central susceptibility pathways and lead to the biological embedment of trauma-related allostatic trajectories through neurobiological alterations even decades later. Lately, there has been an exponential knowledge growth concerning the effect of traumatic stress on oxidative components and redox-state homeostasis. This extensive review encompasses a detailed description of the oxidative cascade components along with their physiological and pathophysiological functions and a systematic presen

Resumen

Las especies reactivas de oxígeno (ROS) actúan como regulador intracelular cuando se generan de forma controlada en puntos concretos de la célula. Modifican la función de proteínas mediante la oxidación reversible de cisteínas. Hay quinasas y fosfatasas de proteínas, factores de transcripción y canales iónicos que están regulados por ROS. Estrés oxidativo y daño celular aparecen cuando los mecanismos antioxidantes de protección son incapaces de mantener bajo el nivel intracelular de ROS. En estas condiciones, ROS inducen pérdida de viabilidad celular en patologías degenerativas de corazón y ce

Resumen

Abstract Protein degradation is a physiological process required to maintain cellular functions. There are distinct proteolytic systems for different physiological tasks under changing environmental and pathophysiological conditions. The proteasome is responsible for the removal of oxidatively damaged proteins in the cytosol and nucleus. It has been demonstrated that proteasomal degradation increases due to mild oxidation, whereas at higher oxidant levels proteasomal degradation decreases. Moreover, the proteasome itself is affected by oxidative stress to varying degrees. The ATP-stimulated 26

Resumen

Excess reactive oxygen species (ROS) can cause an imbalance between oxidation and anti-oxidation, leading to the occurrence of oxidative stress in the body. The most common product of ROS-induced base damage is 8-hydroxyguanine (8-oxoG). Failure to promptly remove 8-oxoG often causes mutations during DNA replication. 8-oxoG is cleared from cells by the 8-oxoG DNA glycosylase 1 (OGG1)-mediated oxidative damage base excision repair pathway so as to prevent cells from suffering dysfunction due to oxidative stress. Physiological immune homeostasis and, in particular, immune cell function are vulne
