Non-Linear Behavior Of Protein And Tannin In Wine Produced By Cofermentation Of An Interspecific Hybrid (Vitis Spp.) And Vinifera Cultivar, Erin L. Norton, Gavin L. Sacks, Joey N. Talbert 2019 Iowa State University

Non-Linear Behavior Of Protein And Tannin In Wine Produced By Cofermentation Of An Interspecific Hybrid (Vitis Spp.) And Vinifera Cultivar, Erin L. Norton, Gavin L. Sacks, Joey N. Talbert

Food Science and Human Nutrition Publications

Wines produced from red interspecific hybrid grape cultivars (Vitis spp.) typically have lower tannin than wines produced from vinifera cultivars, which can be attributed to the lower concentration of tannins and higher concentration of tannin binding proteins of interspecific cultivars. Tannin in wines produced from hybrid cultivars could potentially be increased by blending hybrids with vinifera. We hypothesized that blending of grapes prior to fermentation (cofermentation) should result in final wine tannin concentrations lower than wine tannin concentrations predicted from the individual components due to protein-tannin binding, but that this effect should be absent from monovarietal wines blended post-fermentation. To ...

Food Insecurity And Assistance On Campus: A Survey Of The Student Body, Michael Miller, Gerad Middendorf, Spencer Wood, Sonya Lutter, Scott Jones, Brian Lindshield

Online Journal of Rural Research & Policy

According to recent studies, food insecurity affects from 34%-59% of college students. This will continue to be an issue as tuition increases and more low-income and first-generation students enter universities and colleges. Nearly 52% of college students live at, or near, the poverty level, compared to a national poverty rate of 14.5%. This leaves many undergraduate and graduate students with challenging decisions around meeting their basic housing, nutritional, and educational expenses. To assess food insecurity at Kansas State University (KSU), a random sample of undergraduate and graduate students was surveyed. Findings include a high rate of food insecurity ...

Identification Of High-Risk Food Coping Strategies Of Maine Food Pantry Clients, Kathryn Cutting 2019 University of Maine

Identification Of High-Risk Food Coping Strategies Of Maine Food Pantry Clients, Kathryn Cutting

Electronic Theses and Dissertations

Food coping strategies are strategies adopted by individuals in order to obtain enough food for themselves and their family. Food coping strategies can range from using coupons (couponing) and buying in bulk to skipping meals and stealing food. Although not all strategies are considered to be high risk, all strategies should be accounted for so that nutrition education programming caters to strategies that individuals are employing. This topic has not been widely researched in the United States. The purpose of this study was to identify common food coping strategies of food pantry clients across nine counties in Maine, explore identified ...

There are a variety of situations in an animal’s life when nutrient utilization is reprioritized from productive towards agriculturally unproductive purposes. Two well-known examples that markedly reduce production are heat stress and ketosis. Decreased feed intake, experienced during both disorders, is unable to fully explain production losses. Additionally, both disorders are characterized by negative energy balance, body weight loss, inflammation, and liver fat accumulation. While the metabolism of ketosis and heat stress has been thoroughly studied for the last 40 years, the initial insult in the cascade of events ultimately reducing productivity in both heat-stressed and ketotic cows has ...

3-Hydroxy Fatty Acids Induce Retinal Pigment Epithelial Cell Lipoapoptosis, Mona Hadidi 2019 University of Nebraska - Lincoln

3-Hydroxy Fatty Acids Induce Retinal Pigment Epithelial Cell Lipoapoptosis, Mona Hadidi

Nutrition & Health Sciences Dissertations & Theses

Mitochondrial fatty acid oxidation (FAO) plays an important role in maintaining metabolic homeostasis, especially during catabolic stress. Genetic mutation in gene that encodes for mitochondrial FAO enzymes could result in metabolic stress especially during fasting or hypoglycemic condition. Mutation in the active site residue (1528G>C) of long chain 3-hydroxy acyl CoA dehydrogenase (LCHAD) results in the loss of LCHAD enzyme activity. Children’s with LCHAD mutation were known to accumulate 3-hydroxy fatty acids such as 3-hydroxy palmitic acid and 3-hydroxy myristic acids, long chain free fatty acids, acyl carnitine and 3-hydroxy dicarboxylic acid due to their defective enzyme activity ...

Inhibitory Effects Of Shiitake-Derived Exosome-Like Nanoparticles On Nlrp3 Inflammasome Activation, Yizhu Lu

Nutrition & Health Sciences Dissertations & Theses

The NLRP3 inflammasome is a critical mediator of inflammation and consists of the sensor NOD-like receptor family, pyrin domain containing 3 (NLRP3), the adaptor apoptotic speck protein containing a caspase recruitment domain (ASC), and the effector caspase-1. Dysregulated or excessive activation of the NLRP3 inflammasome contributes to pathogenesis of diverse inflammatory diseases such as Type 2 diabetes and atherosclerosis. Therefore, the NLRP3 inflammasome is a promising therapeutic target for treating these diseases. Extracellular vesicles (EVs) are membrane-enclosed tiny particles released by almost any type of cells and they are involved in the intercellular communication by transferring their cargos including RNAs ...

Efficacy Of Shoes And Boots In Preventing Motorcycle-Related Ankle Inversion., Justin T. Wilder, Mitchell L. Stephenson, Jason C. Gillette

Kinesiology Presentations, Posters and Proceedings

The current investigation explored the potential prophylactic effects of shoes, work boots, and motorcycle boots in reducing ankle inversion associated with ankle sprain. While the majority of previous research has investigated the effects of protective equipment in crashes, rates of lower extremity loading in emergency stop contexts are comparable to jump landings and may induce frontal plane loading that could lead to ankle injury. Fifteen adults wore athletic shoes, work boots, and motorcycle boots in a motorcycle drop task. Motorcycle boots significantly (p = 0.03) decreased peak ankle inversion angles by 3.6 degrees, but also increased (p < 0.01) vertical ground reaction forces by 0.21 bodyweights compared to the other shod conditions. Overall, it is suggested that motorcycle boots can potentially protect motorcycle riders from both crash-based and emergency-stop injuries.
