Antioxidant Effect of Bilberry on Oxidative Stress Caused by Acute Exercise in Rats

This research is supported by Atatürk University Scientific Research Commission. Abstract This study, it was aimed to determine the antioxidant effect of bilberry extract in decreasing the oxidative stress caused by acute exhaustive exercises in rats' blood and liver tissues.  27 Spraque-Dawley type male rats were divided into four groups (control, exercise, bilberry and bilberry+exercise groups). Bilberry extract was administered using gavage once daily. Before blood and liver tissues were taken, the rats ran in a treadmill at a speed of 25 m/min (1.5 km / h) at a slope of 0 for about 1 hour or until exhaustion. Compared to the control group, serum GSH levels and GPx activities did not have a significant change in the bilberry, acute exercise and bilberry + acute exercise groups; while serum MDA levels decreased significantly. When compared to the control group, liver GPx activity significantly increased in the bilberry and bilberry+acute exercise groups. Again, it was determined that liver GSH level significantly increased in bilberry+acute exercise group.The results of this study demonstrate that bilberry extract may provide antioxidant protection against a potential oxidative damage as it causes an increase in hepatic GPx activity and GSH levels in rats exposed to acute exhaustive exercise.

An Analysis of Sprawl and its Alternatives

The suburbs have been an integral part of American history since the mid nineteenth century, a period in which cities began growing in an exponential manner. Over the last one hundred and fifty years, urban and suburban areas and what defines them have undergone an incredible metamorphosis. These changes can be identified in the political, social, and economic arenas; some examples include immigration, federal housing policies, single family houses, industrialization, racial discrimination and segregation, and the development of rural lands away from the city center. Since the end of World War II, much has been written about the topic of urban and suburban sprawl. Most of the writers and historians that I will introduce in this historiography have criticized sprawl as an inefficient development of land. There are a few writers that I studied, however, who are convinced that sprawl\u27s positives outweigh the negatives. Many writers of works on sprawl analyzed in this paper are not historians or history professors; I believe their credentials as economists, city planners, and geographers make them even more qualified to discuss the issue of sprawl than an average historian because they directly work in urban studies. One of the most successful alternatives to sprawl and a popular trend in recent years is mixed-use development, on which I conducted original research in my hometown of Henrietta, NY. Mixed-use development is using a plot of land for more than one purpose. In most cases, mixed-use land contains commercial, industrial, and residential aspects. In the last section of this thesis, I will connect research to teaching by assigning students a project to better understand the town they live in. Various research methods are offered for the students to use, with interviews being the primary method taught
