The aim of this pilot study was to assess the impact of select consumption patterns on the bioavailability of carotenoids from vegetables. On three randomized testing days, subjects consumed equal amounts of fat-free “chef’s salad” ingredients at two meals representing lunch and dinner, along with raw salad vegetables and 8g canola oil split between meals in the following patterns: 100 and 0%; 75 and 25%; and 50 and 50%. Blood was collected from 0-12h and triacylglycerol rich lipoprotein fractions (TRL) were isolated by ultracentrifugation. TRL carotenoid concentrations were analyzed by HPLC-PDA. Considering all carotenoids, absorption was greatest when ≥75% of vegetables were consumed in the first meal (P

Scrafton Carr Timing of Dessert but Not Portion Size Affects Young Children's Intake at Lunchtime http://docs.lib.purdue.edu/hhstheses/6 http://docs.lib.purdue.edu/hhstheses/6 Thu, 31 May 2012 07:05:52 PDT Multiple factors effect children’s capability to make healthy choices when it comes to food intake. A field of study pertaining to pediatric nutrition that has not been well studied relates to children’s modification of food intake in response to the meal served. The purpose of this repeated exposure, randomized, cross-over quasi-experimental study was to determine food preference and portion control in two-to-five year old children of Caucasian and Asian descent (n=23). The study had two within-subject factors (portion size of main course and timing of dessert) and was conducted in West Lafayette, Indiana, from January-April 2011. Whether children participated in the study or not, all children at the child care center were served two study lunches (fish or pasta, each with dessert) twice a week for 12 weeks. The two interventions were: a) an increased portion size by 50% and b) dessert being served with or after the main course. Analyses of variance conducted on energy intake from the main course and dessert at lunch yielded significant portion size x timing of dessert interactions. Serving dessert after the meal was associated with higher kilocalorie (kcal) consumption from the main course (73 versus 64 kcal, P=0.03), from dessert (90 versus 84 kcal, P=0.04), and as total intake at the meal (162 versus 148 kcal, P

Peterson The Effects of Maternal Exercise During Pregnancy on the Vascular Smooth Muscle Cell Function of Offspring http://docs.lib.purdue.edu/hhstheses/4 http://docs.lib.purdue.edu/hhstheses/4 Thu, 31 May 2012 06:48:52 PDT Cardiovascular disease is the leading cause of death worldwide. It has been well documented that exercise decreases the occurrence of cardiovascular events. Since the risk of cardiovascular disease development begins in the intrauterine environment, it is critical to assess the role of exercise in the prevention of cardiovascular disease in the developing offspring. Previous studies have linked increased disease susceptibility with decreased vascular function. Therefore, the purpose of this investigation was to test the hypothesis that maternal exercise during gestation does not have an effect on the vascular smooth muscle cell function of the offspring. Twenty primiparous crossbred gilts were artificially inseminated and randomized into sedentary and exercise groups. The exercised group (n=4) performed 15 weeks of treadmill running. Contrary to our hypothesis, the results demonstrated that offspring from exercised dams had reduced vascular smooth muscle relaxation induced by sodium nitroprusside. This study was the first to investigate the impact of maternal exercise on offspring atherosclerotic disease susceptibility throughout life and potentially determine the origins of cardiovascular disease. Future studies should investigate the underlying causes of these alterations in the vascular smooth muscle cells.

Since consumer engagement is important for the benefits of the Smart Grid to be realized, the readiness and ability of utilities to answer consumer questions is an important issue. Assessing the readiness of utility call centers to address pertinant customer concerns was accomplished by calling utility call centers with Smart Grid projects and asking 6 simple Smart Grid and smart meter questions. The hypothesis being tested for this reasearch is that only a minority of utility companies will have systematically prepared their call centers to answer consumer questions. Results showed that utility companies do not provide enough information through their call centers. There is a significant opportunity for utility call centers to better prepare and educate their customer service representatives and educate and engage utility consumers.
