The young rats were 3 months of age and old rats were 22 months old. The rats were divided into a young control group (n=8), an old control group (n=5), a young experimental group (n=7), and an old experimental group (n=7). Rats in the young and old control groups did not receive any treatment, while rats in both the young and old experimental groups were injected with GSH (250 mg/Kg of body weight) into the peritoneal cavity once a day for a week. At the end of the injection period, the rats were anesthetized and kidneys were harvested. The mitochondrial and cytosolic fractions were separated from rat cortex and medulla by differential centrifugation. GSH concentrations were measured using a spectrophotometric assay. Both mitochondrial and cytosolic GSH levels in kidneys from young and old female Lewis rats were significantly increased with GSH supplementation. The results indicate that kidneys from both young and old rats respond to exogenous dietary supplementation with GSH.

Authors: Williams, Heather Lynn Abstract: This study provides an overview of vacancy and blight within communities across the United States and the significance that these factors play in the overall health and prosperity of the neighborhoods and cities in which they exist. The recent housing boom and eventual bust destabilized neighborhoods and led the federal government to provide funds for communities to combat vacancy and blight through the American Recovery Act and the Dodd Frank Act. The City of Muncie utilized these funds to demolish vacant, blighted properties and to aid developers in the rehabilitation of several historic properties for rental and sale to low-income residents. Although these efforts are an excellent starting point for redevelopment of Muncie’s neighborhoods, there is room for improvement in utilizing private-public relationships and funding sources to amplify current successes. 2013-05-10T00:00:00Z http://cardinalscholar.bsu.edu/handle/123456789/197186 Title: Effect of fatigue on lower extremity mechanics during the unanticipated cutting maneuver Authors: Weiss, Kaitlyn J. Abstract: Fatigue has been observed to affect lower extremity mechanics during the cutting maneuver. However, there is a lack of research examining the effect of fatigue and limb dominance on lower extremity mechanics during unanticipated sidecutting. Objectives: This research sought to assess mechanical differences pre- and post-fatigue and with respect to limb dominance. Design: Repeated measures. Methods: Thirteen female collegiate soccer and field hockey players performed right and left unanticipated sidecutting following the Yo-Yo Intermittent Recovery test (Yo-Yo IR), a two minute treadmill run at a predicted VO2max, and maximum vertical jumps. Mechanical measures of ankle, knee, and hip motion were obtained during the stance phase of the cut. Repeated measures 2x2 ANOVAs were performed to look at fatigue and limb differences. Alpha level set a priori at 0.05. Results: At initial contact and peak stance, significant changes pre- to post-fatigue were observed. At initial contact there was a reduction in knee flexion angles along with increased ankle dorsiflexion angles postfatigue. At peak stance: increased knee adductor moments post-fatigue; greater ankle eversion moments on the dominant limb (DL) as well as increased eversion moments post-fatigue for both limbs. There was a differential effect of fatigue on peak hip abduction angles and hip internal rotation angles at initial contact which were altered in the DL only; decreased hip adductor moments occurred post-fatigue as well as decreased power absorption. Conclusions: Results from this study indicate that lower extremity mechanics are altered as an effect of fatigue such that injury risk may be elevated. 2013-05-10T00:00:00Z http://cardinalscholar.bsu.edu/handle/123456789/197185 Title: Tell us how you really feel: using the implicit association test to measure attitudes towards seeking psychological help Authors: Walrath, Taylor R. Abstract: In this study, an Implicit Association Test (IAT) was created to measure individuals attitudes towards seeking psychological help. The IAT was administered prior to the Beliefs About Psychological Services scale (BAPS; Ægisdóttir & Gerstein, 2009) to examine the relationship between the implicit and explicit measures of attitudes toward seeking psychological help. It was theorized that the implicit measure would be less affected by social desirability and unconscious attitudes than the explicit measure. Standardizing revealed that IAT scores reflected less belief in the expertness of psychology professionals than did BAPS scores. However, participants reported greater intent to seek psychological help on the BAPS compared to the IAT. BAPS scores reflected higher stigma towards psychological services compared to the IAT. Correlations between the implicit and explicit measure were moderate for stigma and perceived expertness of psychology professionals but low for intent to seek psychological help. 2013-05-10T00:00:00Z
