Abstract:

Oxidative processes play important role in cell physiology and pathology as well. Balance of these processes is supplied by cooperating antioxidative systems; function of antioxidant defense systems depens on high levels of antioxidants in organism. Presented work is focused on developement and optimization of methods for analysis of important enzyme and non-enzyme antioxidants as well as total antioxidant capacity of selected types of biological material. Extractions and analyses of vitamin E, carotenoids, superoxide dismutase, catalase, peroxidase and lipoxygenase in barley and malt were opt

Abstract:

Many secondary plant compounds are capable of photoactivation resulting in the production of toxic species of oxygen. One mechanism of defense for insects feeding on phototoxic plants may be the presence of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPOX), and glutathione reductase (GR). The activities of these enzymes were examined in larvae of three lepidoptera: Ostrinia nubilalis, Manduca sexta, and Anaitis plagiata. Highest levels of antioxidant enzyme activity were found in A. plagiata, a specialist feeder on Hypericum perforatum, which

In theoretical part individual low-molecular weight antioxidants and enzymes are described. The main causes of fruit decay and some possibilities of fruit preservation and storage are summarized. As biological material some common fruits were chosen - green and red apples, peaches, plums and white grapes. The fruits were stored in laboratory, cellar, in refrigerator and in freezer.

Abstract:

Mn-salophen complex with superoxide-scavenging activity was prepared from manganese(III) acetate dihydrate and salophen in ethanol. Visible absorption spectrum of the red-brown solution exhibited a broad absorption band at 430 - 450 nm with two shoulders between 500 and 600 nm which were absent with either salophen or manganic acetate alone. Titration of salophen with manganese(III) was consistent with a 1:1 Mn to salophen stoichiometry of the complex based on changes in the absorbance at 500 nm or of superoxide scavenging activity.

Abstract:

Abstract Antioxidants function as blockers of radical processes and eliminate harmful reactive oxygen species (ROS) produced during normal cellular metabolism. A complex antioxidant defence system has evolved to protect the cellular homeostasis. This system includes antioxidant enzymes (AOEs), such as superoxide dismutases (SODs), which are intracellular MnSOD and CuZnSOD and extracellular ECSOD, H2O2 scavenging enzymes catalase and glutathione peroxidase, and hemeoxygenase-1 (HO-1), an important enzyme in heme metabolism, which has also been suggested to have antioxidant capacities.

Glutathione peroxidase is responsible for reducing peroxides into their corresponding alcohols and water.

Abstract:

>Magister Scientiae - MSc<br>South Africa is one of two countries responsible for the production of approximately 80% of the world’s Zr. The increase in mining activity has detrimental effects on the environment, especially crop plants, as more pollutants are leached into the soil. Consequently, it is necessary to understand how plants respond to this form of abiotic stress. Therefore, this study focused on determining the physiological and biochemical responses of two genotypes of Brassica napus L (Agamax and Garnet) in response to Zr stress. The levels of cell death, lipid peroxidation an

Abstract:

O café, rico em substâncias bioativas, está entre os maiores contribuintes para a ingestão de antioxidantes em vários países. O tipo de torra dos grãos influencia em sua atividade antioxidante. Estudos indicam que o consumo moderado de café filtrado está envolvido na redução do risco de doenças crônicas não-transmissíveis, geralmente associadas entre si e que se constituem em graves problemas de saúde pública. Entretanto, a literatura não apresenta consenso sobre a ação benéfica do café na redução do risco destas doenças. Objetivos: Comparar a atividade antioxidante de dois graus de torras de

Abstract:

Os compostos fenólicos são substâncias amplamente distribuídas no reino vegetal, em particular nas frutas e em outros vegetais. Estes compostos, destacando-se flavonoides e os ácidos fenólicos, devido à estrutura molecular, podem apresentar a capacidade de inibir processos oxidativos. Além do mais, estão relacionados com a redução de risco de doenças crônicas não transmissíveis tais como: cardiovasculares, câncer, aterosclerose, entre outras. Considerando a elevada produção de caju em território brasileiro e a possibilidade da existência de compostos com potencial antioxidante no pedúnculo de

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>The deficit of estrogen that accompanies menopause may be involved in the metabolic changes and increased oxidative stress during non-reproductive female life. Hormone replacement therapy (HRT) has been used to attenuate the menopausal symptoms. It is prescribed either as the replacement of estrogen alone or the combination of estrogen with progestins. Superoxide dismutase (SOD) is a key enzyme in the control of reactive oxygen species levels and SOD modulators may have potential use as therapeutic agents in oxidative stress-associ
