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:

Phragmites australis (Cav.) Trin. ex Steud. is a hydrophyte particularly resistant to harsh conditions, e.g. drought, high salinity, contaminants, such as heavy metals and toxic molecules, and high nutrients concentrations. These resistances render the plant suitable for water depuration, where its particular metabolism is exploited to remove pollutants and excessive nutrients from the environment. In constructed wetlands, this principle is applied to phyto-purify wastewater with various origins, such as industrial, agricultural and household, with the aim to improve its quality to an extent w

Abstract:

Active packaging by radical scavenging of the free radical species involved in the biochemical degradation of food is an innovative way to extend the shelf-life of a food product. Current drivers such as consumer’s demand for safer, “healthier,” and higher-quality foods have led to the development of new packaging materials which contain natural extracts. This kind of materials could act as free radical scavengers and thus permit to avoid the use of synthetic and dangerous for the human health antioxidant. In this work, multilayer polymeric materials of different types containing natural ext

Abstract:

Synthetic antioxidants have traditionally been added directly to food products in a single initial dose to protect against oxidation of lipids and generation of free radicals. Natural antioxidants have been shown to undergo loss of activity and become prooxidants at high concentrations; therefore, a need exists to develop active packaging which can gradually deliver antioxidants in a controlled manner. The objectives of this research were to (1) form and characterize cyclodextrin inclusion complexes with the natural antioxidants, alpha-tocopherol and quercetin, (2) incorporate cyclodextrin i

Abstract:

Duchenne muscular dystrophy (DMD) is a progressive muscle wasting disease affecting 1 in every 3500 boys. The disease is characterized by the absence of the dystrophin protein from the sarcolemma of muscle cells. Muscle cells lacking dystrophin go through cycles of degeneration and regeneration and are considered susceptible to contraction-induced injury 144. Eventually, the satellite cell proliferative capacity is exhausted and the muscle fibers are replaced by connective and adipose tissue that yields a progressive loss of force generating capability.

碩士<br>國立臺灣海洋大學<br>水產養殖學系<br>103<br>This study was to find out the dietary effects of four natural antioxidant supplements on rearing performance, antioxidant capacity, immune response, physiological reaction and resistance to hypoxia stress of white shrimp (Litopenaeus vannamei). Four kinds of natural antioxidants used are astaxanthin (AX), curcumin (CU), Salvia extract (SA) and sesame extracts (SE). Each supplement was incorporated into a basal diet with the same diphenylpicryihydrazyl (DPPH) antioxidant capacity. These 4 diets and a control diet(C) without supplement were fed to the shrimp f

碩士<br>國立陽明大學<br>生物化學研究所<br>88<br>Abstract Oxidative modification of low-density lipoprotein (LDL) is an important risk factor and the uptake of oxidized LDL (oxLDL) by macrophages is also a critical step in atherogenesis. The purpose of this study is to delineate the effects of endogenous and exogenous components on oxidation of LDL and lipid transport. The effect of apoHDL, prepared by delipidation of HDL, on Cu2+ or cell-mediated LDL oxidation was examined. The results from analyses of conjugated diene (CD), thiobarbituric acid reactive substance (TBARS) and agarose gel

Extended boar semen are packed in and shipped with a special designed box to maintain the temperature in a range between 15-18℃. This is not an effective way because changes in environmental temperature may ruin sperm quality during shipping. Extended semen packages may be shipped at 4℃, which is an available service offered by many transportation companies and prevents sperm from temperature variation. However this may introduce cold shock to the sperm an

Low-molecular-weight chitosan (LMWC) and chitooligosaccharides (COS) are degraded products of chitosan polymer. The greater solubility and low viscosity of LMWC and COS attract the interest of many researches to utilize LMWC and COS for various applications. For a breakthrough in utilization, chemical modification of LMWC and COS w

Postmenopausal women will lead to higher oxidative stress, declined metabolism, and degenerate physiological function. The previously researches demonstrated that diet restriction and exercise could be beneficial to antioxidant capacity and cardiac function. The influence of low methionine combined exercise training in postmenopausal rats of heart is still unclear. The purpose is to investigate the effect of low methionine diet
