Through a common garden (provenance) experiment, we investigated the metabolic responses to climatic stress with regard acclimation potential of different European beech (Fagus sylvatica L.) populations. Selected enzymatic and non-enzymatic antioxidants were analyzed in leaves. Peroxidase (POD) polyphenol oxidase (PPO) enzyme activity, total protein content as well ABTS [2.2’-azino-bis-(3-etylb...

The study assessed the individual and interactive role of acetylsalicylic acid (ASA) nitric oxide (NO) against excess copper (Cu) concentrations. Excess Cu significantly reduced growth photosynthesis, although application ASA NO mitigated reduction with much visible effect in their combination. oxidative effects have been evident as increased reactive oxygen species (ROS) production, resulting ...

Active oxygen species are produced as a consequence of normal aerobic metabolism. Of these, free radicals are usually metabolized or inactivated in vivo by a team of antioxidants. Individual members are a trained team fighting antioxidants to prevent the generation of ROS, destroy or oxidizing potential of capture. In terms of physiological oxidative stress, induced tissue attack is minimal. A ...

Cells continuously produce free radicals and reactive oxygen species (ROS) as part of metabolic processes. These free radicals are neutralized by an elaborate antioxidant defense system consisting of enzymes such as catalase, superoxide dismutase, glutathione peroxidase, and numerous non-enzymatic antioxidants, including vitamins A, E and C, glutathione, ubiquinone, and flavonoids. Exercise can...

Cigarette smoke is injurious to both oral cavity and internal body environment. Saliva is the firstbody fluid to encounter the dangerous smoke. The aim of our present study was, therefore, toevaluate the influence of smoking on the antioxidant activity of saliva of healthy smokers.Antioxidant capacity of saliva was determined using different methods in the centrifuged saliva from25 male smokers...
