This study evaluates FishWise to determine its effectiveness in educating consumers about sustainable fishery issues and in influencing purchases of sustainable seafood …

Factors In Bmi Increase Among Multicultural Freshmen., Leah Haritan

Master's Theses

This observational research examines body mass index (BMI) changes in multicultural freshmen attending a large public urban university. It explores factors associated with BMI increase and investigates behavior changes and perceptions related to diet and body weight. The study utilizes an online survey distributed in November 2007 and again in April 2008. All 3,260 freshmen were eligible to participate. Initial response rate was 23%; 44% of initial respondents completed both surveys (N = 337). Results revealed a significant increase in BMI for on-campus residents, Caucasians, and males (P < 0.05). Decreased vegetable intake was associated with a BMI increase of less than one (P < 0.05). Fruits and vegetables were perceived by most as healthful; their high cost, and limited variety and availability on campus were deemed potential barriers to intake. Freshman weight gain may be a function of gender, residence, and ethnicity, and deserves further examination.

The Effects Of Aging On Muscle Loss And Nuclear Factor Kappa-B Levels In Rats Fed A Diet Containing Suboptimal Leucine Levels, Corinne Rose Kohlen

Master's Theses

Loss of muscle due to aging is often associated with significant detrimental effects. Therefore, it is crucial to understand signaling molecules that may trigger the muscle loss or prevent the process. The transcription factor, Nuclear Factor Kappa-B (NF-κB), is associated with both catabolic and anabolic pathways of muscle metabolism and may be involved in age-related muscle loss. Leucine is an essential amino acid that is required for both protein synthesis and intracellular signaling pathways that regulate protein synthesis and degradation. The current study examined muscle NF-kB levels in male Sprague-Dawley rats, aged 6 (adult) and 21 months (old) fed a …
