Tissue-Specific Alterations Of Methyl Group Metabolism With Dna Hypermethylation In The Zucker (Type 2) Diabetic Fatty Rat., Kelly T. Williams, Kevin Schalinske 2016 Iowa State University

Tissue-Specific Alterations Of Methyl Group Metabolism With Dna Hypermethylation In The Zucker (Type 2) Diabetic Fatty Rat., Kelly T. Williams, Kevin Schalinske

Kevin Schalinske

BackgroundAltered methyl group and homocysteine metabolism were tissue-specific, persistent, and preceded hepatic DNA hypomethylation in type 1 diabetic rats. Similar metabolic perturbations have been shown in the Zucker (type 2) diabetic fatty (ZDF) rat in the pre-diabetic and early diabetic stages, but tissue specificity and potential impact on epigenetic marks are unknown, particularly during pathogenesis.

Methods ZDF (fa/fa) and lean (+/?) control rats were killed at 12 and 21 weeks of age, representing early and advanced diabetic conditions. Blood and tissues were analysed with respect to methyl group and homocysteine metabolism, including DNA methylation.

Results At 12 weeks, hepatic ...

Mapping Of Iron And Zinc Quantitative Trait Loci In Soybean For Association To Iron Deficiency Chlorosis Resistance, Keith E. King, Gregory A. Peiffer, Manju B. Reddy, Nick Lauter, Shun Fu Lin, Silvia R. Cianzio, Randy C. Shoemaker

Manju B. Reddy

Iron deficiency chlorosis (IDC) in soybean results in yield losses or in extreme cases death. Breeding for resistance has shown limited success with no cultivar having complete resistance. Mineral content of the soybean could be an indicator of the ability of the plant to withstand the effects of IDC. Iron (Fe) and zinc (Zn) concentration was examined in soybean seed and leaves. SSR, RFLP, and BARCSOYSSR markers were used to construct a linkage map used for mapping of Fe and Zn concentrations. The QTL analysis for the combined data identified one major QTL for seed Fe accumulation on chromosome 20 ...


Echinacea Sanguinea And Echinacea Pallida Extracts Stimulate Glucuronidation And Basolateral Transfer Of Bauer Alkamides 8 And 10 And Ketone 24 And Inhibit P-Glycoprotein Transporter In Caco-2 Cells, Zhiyi Qiang, Catharine Hauck, Joe-Ann McCoy, Mark P. Widrlechner, Manju B. Reddy, Patricia A. Murphy, Suzanne Hendrich 2016 Iowa State University

Echinacea Sanguinea And Echinacea Pallida Extracts Stimulate Glucuronidation And Basolateral Transfer Of Bauer Alkamides 8 And 10 And Ketone 24 And Inhibit P-Glycoprotein Transporter In Caco-2 Cells, Zhiyi Qiang, Catharine Hauck, Joe-Ann Mccoy, Mark P. Widrlechner, Manju B. Reddy, Patricia A. Murphy, Suzanne Hendrich

Manju B. Reddy

The use of Echinacea as a medicinal herb is prominent in the United States, and many studies have assessed the effectiveness of Echinacea as an immunomodulator. We hypothesized that Bauer alkamides 8, 10, and 11 and ketone 24 were absorbed similarly either as pure compounds or from Echinacea sanguinea and Echinacea pallida ethanol extracts, and that these Echinacea extracts could inhibit the P-glycoprotein transporter in Caco-2 human intestinal epithelial cells. Using HPLC analysis, the permeation rate of Bauer alkamides by passive diffusion across Caco-2 cells corresponded with compound hydrophilicity (alkamide 8 > 10 > 11), independent of the plant extract matrix. Both ...

Professional Agricultural Workers Journal

Abstract

Interest in local and regional food production has been growing in the last few years. The study, therefore, assessed consumer attitudes and beliefs regarding local or regional livestock products. Data were obtained from a convenience sample of 384 participants from several counties of Georgia, and were analyzed by descriptive statistics, including chi-square tests. A majority of respondents thought using chemicals and additives in locally or regionally produced beef or goat meat was a serious or somewhat serious hazard. Consequently, many were willing to pay more for meat certified as locally or regionally produced. Furthermore, a majority agreed or strongly ...


Improve Food Safety Of Chinese Restaurants In Kansas Through Multicultural Intervening Measures, Shijun Yan, Autumn Schuck 2016 K-State Confucious Institute

Improve Food Safety Of Chinese Restaurants In Kansas Through Multicultural Intervening Measures, Shijun Yan, Autumn Schuck

Institute for Student Learning Assessment

Chinese restaurants' food safety problems have attracted the attention of food safety regulators. According to the many feedback of the state food safety inspectors, there are more problems in the operations of Chinese restaurants than in those others. The probability of repeating the same mistakes is also high in the review of the violation items in the inspection reports. Due to the number of violating behaviors in Chinese restaurants, food safety inspectors have to do many follow-up inspections, and this causes much waste of human resources.

The purpose of this study was to enable Chinese restaurant practitioners to understand US ...

Testing Predictions Used To Build An Agrivoltaics Installation On A Small-Scale Educational Model, Katie Kinney, Rebecca Minor, Greg Barron-Gafford

STAR (STEM Teacher and Researcher) Presentations

Models are valuable tools for explaining and testing systems. Small-scale models can be especially useful for educational purposes. For models to be useful, they have to accurately depict the larger system that they are describing. A novel man-made system, known as an agrivoltaic structure, is being constructed at Biosphere 2 near Oracle, Arizona. The word agrivoltaic is a combination of agriculture and photovoltaics, or solar farming. My research involved creating a small-scale version of this system for educational purposes. The model of this system tested two predictions: that plants will grow better in the shade of a panel and that ...

A Three-Year Level Study Of The Profitability Of Corn And Soybean Production, Todd D. Davis, William M. Edwards

william edwards

Crop producers face many decisions each year about the quantity and quality of inputs to use, the purchasing of these inputs, and the timing of production operations. Because their time for gathering and analyzing information on which to base management decisions is limited, they need to know which decision, areas have the greatest impact on profitability. A set of detailed and accurate records of production, costs, and returns from a group of producers growing corn and soybeans in Iowa over a three-year period was.available from Iowa State University Extension. This information was used to assess the relative importance of ...

Characterization Of Extraction Methods To Recover Phenolic-Rich Extracts From Black Beans (Phaseolus Vulgaris) That Inhibit Alpha-Amylase And Alpha-Glucosidase Using Response Surface Approaches, Mazen Alharbi

Nutrition & Health Sciences Dissertations & Theses

Black beans contain high phenolic contents that are considered potent antioxidants. Relatively little is known about their ability to inhibit the carbohydrate-hydrolyzing enzymes α-amylase and α-glucosidase from releasing glucose from starch and/or disaccharides. The objective of this project was to determine the optimum procedures for extracting total phenols (TP), total flavonoids (TF) and total condensed tannins (TCT) from black beans (Phaseolus vulgaris), and then to determine the ability of the phenolic rich extracts to inhibit α-amylase and α-glucosidase. Due to their high phenolic levels, it was hypothesized that black beans would be an effective inhibitor of α-amylase and α-glucosidase ...

Feasibility, Safety, Economic And Environmental Implications Of Whey-Recovered Water For Cleaning-In Place Systems: A Case Study On Water Conservation For The Dairy Industry, Yulie E. Meneses 2016 University of Nebraska-Lincoln

Feasibility, Safety, Economic And Environmental Implications Of Whey-Recovered Water For Cleaning-In Place Systems: A Case Study On Water Conservation For The Dairy Industry, Yulie E. Meneses

Dissertations & Theses in Food Science and Technology

Several countries around the world are facing the challenge of producing food with limited water resources for a growing population. This reality is forcing all sectors involved in the food supply chain to look for water conservation strategies that contribute to assure global food security. Besides water consumption, the food industry has to deal with wastewater generation; therefore, water reconditioning and reuse is an attractive solution to address both issues. The goal of this research was to demonstrate that high quality water can be recovered from whey, a by-product of the cheese making process, and reused in cleaning-in place (CIP ...

Evaluation Of Protein Source At Breakfast On Energy Metabolism, Metabolic Health, And Food Intake: A Pilot Study, Lauren A. Cambias

Human Nutrition and Hospitality Innovation Undergraduate Honors Theses

Abstract

Over 30% of adults in the US are obese. A primary contributor to obesity is an unhealthy diet related to imbalanced macronutrients. Diets higher in protein (PRO) are associated with increased energy expenditure (EE) and reduced food intake. The objective of this pilot study was to determine if protein source at breakfast influences EE in young men (n=4; ages 18-35). Participants consumed three isocaloric (whey (WP), pea (PP), beef (BP); 275 kcal, 62% PRO, 23% CHO, 15% Fat) drinks in randomized, crossover design with a one-week washout period. Each test day EE, appetite, and cravings were assessed at ...


Odor-Induced Taste Modifications In Teas, Rachel Elizabeth Isaacs 2016 University of Tennessee - Knoxville

Odor-Induced Taste Modifications In Teas, Rachel Elizabeth Isaacs

Masters Theses

Although odorants and tastants are perceived by two different sensory modalities, the perceived taste qualities of a solution may be modified with the addition of an odorant. While many studies have investigated odor-induced taste modifications in model solutions, there is a lack of conducted research examining odor-induced taste modifications in complex food systems. The research objective was to determine the effect of added vapor-phase stimuli on the perceived sweetness of a model solution and complex food system.

Eight vapor-phase stimuli (i.e. blueberry, caramel, ginger, honey, lemon, orange, peach, and strawberry) were selected for investigation. The study was conducted in ...


The Food Industry’S Perception Of Economically Motivated Adulteration And Related Risk Factors, Lindsay Colleen Murphy 2016 University of Tennessee - Knoxville

The Food Industry’S Perception Of Economically Motivated Adulteration And Related Risk Factors, Lindsay Colleen Murphy

Masters Theses

The United States of America has numerous safeguards in place to protect our food supply, including federal regulations and the food and beverage industry’s dedication to food safety. One of the issues that the food and beverage industry continuously battles is the prevalence of intentional adulteration. The Food Safety Modernization Act (FSMA) specifically addresses intentional adulteration and its sub-category of economically motivated adulteration (EMA) by requiring all facilities that supply food to the US to assess the vulnerabilities within their operation in order to prevent events that could cause public harm. The purposes of this study are threefold: (1 ...

The Archaeology Of Appetites, Molly S. Schonert 2016 University of North Carolina at Charlotte

The Archaeology Of Appetites, Molly S. Schonert

SEWSA 2016 Intersectionality in the New Millennium: An Assessment of Culture, Power, and Society

Through use of examining how food is produced, stored, distributed and consumed, one can take a glimpse into the past, present and even future of this planet–to better understand the complexity of human identity and the social practices or roles that define an individual, community or society. So this begins an exploration of the archaeology of food as a gendered commodity throughout our evolutionary past, emphasizing the infinite ways in which foodway practices exceeds the nutritional value of what our ancestors, family, friends and ourselves consume(d) on a daily basis. Foodways practices is an invaluable tool in any ...

Hunger Doesn't Take A Spring Break, Jessica Isaacs

Engagement and Service-Learning Summit

The rates of food insecurity amongst Hoosier children is slightly above the national average. For many of these children, school lunches are their primary source of nutrition. During school breaks, these children are at risk of going hungry. While Purdue Nutrition Society wishes that we could help all Hoosier children stay fed with nutritious meals, for now we are focusing on helping 20 local elementary students most at risk of going hungry over spring break. Working with Glen Acres Elementary in Lafayette, Indiana, a school where in 2014, over 71% of the students qualified for free or reduced lunches, we ...

Effects Of Three-Times Daily Diet Soda Consumption For One Week On The Composition Of The Gut Microbiome In Healthy Young Adults, Jenna Abdelhadi, Domenica Simone, Charles Hadley King, Raja Mazumder, Keith A. Crandall, Allison C. Sylvetsky-Meni

GW Research Days 2016 - Present

Epidemiologic studies report associations between artificial sweetener (ASW) consumption and metabolic abnormalities, yet well-designed human intervention studies in humans are limited. Given that ASW contain no or few calories, one potential mechanism through which ASW may influence metabolic risk is through altering the gut microbiota. As alterations in the gut microbiota are known to be implicated in the development of metabolic disease, the purpose of this study was to investigate the effects of one week of three times daily diet soda (with ASW) consumption on the gut microbiota in healthy college students. We hypothesized that participants randomized to consume diet ...
