14. Can Triamcinolone acetonide, platelet-rich plasma, and pentosan polysulfate sodium induce oxidative stress in cultured equine chondrocytes?
RESUMO: A deterioração progressiva e perda da cartilagem articular são os eventos finais da osteoartrite (OA). Espécies reativas de oxigênio (ROS) têm papel importante na atividade catabólica de condrócitos, levando a morte celular e quebra dos componentes da matriz. Injeções intra-articulares de corticosteroides, como com o acetonido de triancino

15. Protective effect of Schisandra chinensis total lignans on acute alcoholic-induced liver injury related to inhibiting CYP2E1 activation and activating the Nrf2/ARE signaling pathway
ABSTRACT Schisandra chinensis (Turcz.) Baill., Schisandraceae, is a well-known traditional Chinese medicine used mainly as a recipe for hepatoprotection. Modern researches have revealed that the hepatoprotection is related to its lignans and crude polysaccharide. In this study, we examined the effect and mechanism of S. chinensis total lignans on the liver i

16. Adaptation of plants to high-calcium content kart regions: possible involvement of symbiotic microorganisms and underlying mechanisms
Resumo Os microorganismos e endófitos da rizosfera podem ajudar seus hospedeiros a absorver nutrientes e regular os níveis de hormônios vegetais. Além disso, eles podem modular as expressões dos genes hospedeiros, auxiliar os hospedeiros na eliminação de espécies reativas de oxigênio (ROS) e secretar compostos orgânicos voláteis. Portanto, microor

17. Hydrogen sulfide protects H9c2 cardiomyoblasts against H2O2-induced apoptosis
Reactive oxygen species (ROS) are highly reactive chemical species that may cause irreversible tissue damage, and play a critical role in cardiovascular diseases. Hydrogen sulfide (H2S) is a gasotransmitter that acts as a ROS scavenger with cardio-protective effects. In this study, we investigated the cytoprotective effect of H2S against H2O2-induced apoptos

19. RESISTANCE EXERCISE PROTOCOL DOES NOT CAUSE ACUTE GENOTOXIC EFFECTS IN TRAINED INDIVIDUALS
RESUMO Introdução: O treinamento resistido, principalmente a musculação, vem progressivamente ganhando novos adeptos em todo o mundo. Apesar de haver um significativo aumento no número de pesquisas e na literatura disponível sobre o assunto, o treinamento resistido vem passando por um importante processo de evolução. O metabolismo anaeróbico, que c

20. Relationship between Electrochemical Parameters, Cytotoxicity Data against Cancer Cells of 3-Thio-Substituted Nor-Beta-Lapachone Derivatives. Implications for Cancer Therapy
Electrochemical methods are powerful in the characterization and design of redox-modulating agents. We, herein, report the electrochemical investigation, in aprotic medium, of eleven synthetic 3-thio-substituted-nor-beta-lapachones, along with the determination of cytotoxic activity and correspondent selectivity index, against several cancer cell lines and o

21. Nitrogen source influences the antioxidative system of soybean plants under hypoxia and re-oxygenation
ABSTRACT: In this work, we compared nitrate-supplied plants (non-nodulated) with non-nitrate-supplied plants (nodulated) under oxygen privation of root system (hypoxia) and re-oxygenation (post-hypoxia; recovery) in order to verify whether N sources affect the antioxidant system during oxidative stress caused by hypoxia and post-hypoxia conditions. Antioxida

22. Brassinosteroids Reciprocates Heavy Metals Induced Oxidative Stress in Radish by Regulating the Expression of Key Antioxidant Enzyme Genes
ABSTRACT Heavy metal toxicity in plants lead to accumulation of reactive oxygen species (ROS). Antioxidant enzyme system is also not able to revert altered ROS homeostasis. The present study reports the heavy metal induced ROS toxicity by up-regulating the expression of key antioxidant enzyme genes through Brassinosteroids pre-soaking treatment in radish.

23. In Vitro Study Towards Role of Acrylamide-Induced Genotoxicity in Human Lymphocytes and the Protective Effect of L- Carnitine
ABSTRACT Acrylamide (AA), is an important industrial compound, formed during food processing under high temperature. Due to its potential carcinogenic effect, it has been recognized as a human health concern. In this study, we investigated the role of oxidative stress in acrylamide’s genotoxicity and protective role of L- carnitine (LCA) in human lymphocyt

24. Adiponectin is protective against endoplasmic reticulum stress-induced apoptosis of endothelial cells in sepsis
Endoplasmic reticulum (ER) stress is a critical molecular mechanism involved in the pathogenesis of sepsis. Hence, strategies for alleviating this stress may be essential for preventing cardiovascular injuries under sepsis. Adiponectin is secreted by adipocytes and its levels are decreased in sepsis. The purpose of this study was to investigate the protectiv
