The objective of the present study is to evaluate the beneficial effect of tomatoes, which are rich source of Lycopene, relatively
a new carotenoid known to play an important role in human health and disease. In this study lipid peroxidation rate was measured
by estimating Malondialdehyde and the levels of serum enzymes involved in antioxidant activities like Super Oxide Dismutase,
Glutathione Peroxidase, Glutathione Reductase, Reduced Glutathione, in type-II diabetic group (n=40) and age matched control
group (n=50), and observed significantly lower levels of antioxidant enzymes and very high lipid peroxidation rate in type-II
diabetes when compared to control group (p<0.001). Short term supplementation with tomatoes (cooked) to diabetic group for
a period of 30 days, showed a significant improvement in antioxidant enzyme levels (p<0.001) and decreased lipid peroxidation
rate (p<0.001) suggesting the supplementation with tomato lycopene may serve as the best method of preventing the oxidative
stress in diabetic patients. 相似文献

以2018赛季中国足球超级联赛全部240场比赛的净比赛时间以及死球消耗时间为数据为例,通过与2014-2018赛季中超联赛净比赛及死球状态相关数据对比、中超联赛个案分析以及影响中超联赛净比赛的主客观因素进行分析。研究结果表明:中超净比赛时间有所提高,但据60min的净比赛时间目标还有一定的差距;造成中超联赛死球的8项常规死球类型消耗最多的是任意球、第二是界外球、第三是球门球、第四是角球、第五是进球后重新开球、第六是越位、第七是坠球、第八是球点球;中超联赛首次引入VAR介入,平均每次耗时2min22s29,虽然单次耗时较高,但总耗时量仅排第七,这表明:中超VAR的介入,在保证中超联赛公平公正的基础上,其对2018赛季中超联赛的净比赛时间的影响并不是主要因素。 相似文献

AbstractThis paper examines the development of American football and the Super Bowl in the British imagination utilizing data from the British press. Divergent images of America have been present for centuries in British minds, and American football became intertwined with these images in the nineteenth century. Initially presented as a brutalized version of British varieties of football, once American football was seen live in Great Britain and it became a familiar subject on newsreels, some commentators interpreted it as a spectacle and a synonym for American life–modern, exciting, fast, and fun. Others viewed it as a threat that could undermine the British cultural heritage. The regular broadcasting of the NFL by Channel 4, including the Super Bowl live, was a watershed with the game swiftly gaining audience numbers whilst English association football was in a dour period. The increased popularity resulted in more media coverage, including negative images of unbridled capitalism, fixed games, and drug use. By the 1990s, audience numbers declined as English football was rehabilitated and American popularity waned, mainly through unpopular foreign policies. Today, many Britons regard watching the Super Bowl in the same way as a trip to Disney, an one-day holiday to a ‘foreign’ culture. 相似文献

AbstractIn the days following Super Bowl III, New York Times columnist Robert Lipsyte coined the phrase ‘superbowling’. Consisting of the ‘chatter’ and diverse perspectives voiced throughout the nation in the days surrounding each Super Bowl, superbowling includes the off-the-wall psychiatric evaluations and epic gloating by football fans, political reactions and sociological analyses concerning the game’s affect on the nation’s institutions, as well as the hasty generalizations by alarmed moralists and university professors. This paper utilizes the ‘superbowling’ penned between Super Bowls I and XXXVI as evidence that provides insight into ‘the variety of ways in which Americans understood and enacted their political culture at a specific time’. By investigating the varieties of superbowling topics highlighted within each yearly Super Bowl, one cannot only better understand the evolution of Super Bowl Sunday, but can also understand its relationship to the prominent historical happenings and personalities of the time. It is concluded that by the turn of the millennium, superbowling revealed at least three enduring qualities of Super Bowl Sunday: ‘conspicuous consumption’, ‘shared experience’, and ‘national holiday’. 相似文献
