The Role Of Diet In The Onset Of Depression: A Biochemical Connection Between Nutrition And Mental Health, Katlin Wildeman

Senior Honors Theses

Depression is a major clinical concern, having a complex onset and the presence of multiple, often unidentifiable causes. Depression affects millions of individuals worldwide, with a high prevalence in regions of the world with a Western-style diet as compared to regions with a Mediterranean diet. A Western-style diet consists of foods high in sugar, fat, and processed meats and grains, whereas the Mediterranean diet contains significantly more vegetables, fruits, lean meats, and whole grains. The link between diet and mental health disorders has implications for individuals of all ages who are hesitant to turn to medication. In addition to presenting …

Seaweeds As Nutraceuticals For Health And Nutrition, Emer Shannon, Nissreen Abu-Ghannam

Articles

Throughout human history, seaweeds have been used as food, folk remedies, dyes, and as mineral-rich fertilisers. Seaweeds as nutraceuticals or functional foods with dietary benefits beyond their fundamental macronutrient content are now a major research and industrial development concept. The occurrence of dietary and lifestyle related diseases, notably type 2 diabetes, obesity, cancer, and metabolic syndrome has become a health epidemic in developed countries. Global epidemiological studies have shown that countries where seaweed is consumed on a regular basis have significantly fewer instances of obesity and dietary-related disease. This review outlines recent developments in seaweed applications for human health from …

Food Insecurity: United States, Courtney Handzel

Global Issues in Public Health

Food insecurity is a global issue and has caused struggles to millions of people, specifically in the United States. This environmental issue involves not having the resources to obtain adequate food supply. The economic and social influences that affect food insecurity leave vulnerable populations, such as low-income families and minority races, at a greater disadvantage. This issue causes serious health complications to arise too, the most common being diabetes. The increased risk of diabetes due to food insecurity has been studied on several occasions and the results all show the correlation, lack of food security increases the risk of diabetes. …

Whole Grain Processing And Effects On Carbohydrate Digestion And Fermentation, Sandrayee Brahma

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Whole grains are a major source of dietary fibers in the human diet that provide specific nutrients to the gut microbiota and thereby plays a major role in modulating microbiota composition and increasing diversity of the gut ecosystem. A common approach of consuming whole grains is in the form of ready-to-eat extruded breakfast cereals. Studies reported herein established that extrusion conditions not only affected the physicochemical properties but also in vitro starch digestibility, β-glucan extractability and in vitro fermentation characteristics of whole grain oats. Moderate screw speed (300 rpm) led to higher slowly digestible starch (SDS) with an accompanying decrease …

Advances In Control Of Food Mixing Operations, Patrick J. Cullen, Serafim Bakalis, Carl Sullivan

Articles

Mixing is a ubiquitous unit operation within the food industry and employed not only to combine multiple ingredients, but also to control reactions and modify the structure of foods. Failure of the mixing process may result in poor quality, organoleptic or functional attributes of foods along with product safety concerns. The industry is increasingly adopting automation and advanced control strategies such as Process Analytical Technology. Sensors can provide both insights into the complex mechanisms of mixing along with effective control. Here we discuss some recent advances in the control of food mixing operations.

College Student Perceptions On Campus Alcohol Policies And Consumption Patterns, Brenda L. Marshall, Katherine J. Roberts, Joseph Donnelly, Imani N. Rutledge

Department of Public Health Scholarship and Creative Works

Environmental strategies for colleges and universities to reduce alcohol consumption among their students include the development and enforcement of campus alcohol policies. This study examines students' knowledge and attitudes toward campus alcohol policies and how they relate to alcohol consumption and alcohol social norms. A sample of 422 freshman students was surveyed during their first month at a 4-year public college. Findings indicated that the majority of students (89%) were aware of campus policies, yet of those who were aware, less than half (44%) were accepting of these campus rules and regulations. In addition, the majority (79%) of students drank …

Peer-Led, School-Based Nutrition Education For Young Adolescents: Feasibility And Process Evaluation Of The Teens Study, Mary Story, Leslie A. Lytle, Amanda Birnbaum, Cheryl L. Perry

Desulfovibrio Desulfuricans G20 Tetraheme Cytochrome Structure At 1.5 A˚ And Cytochrome Interaction With Metal Complexes, Mrunalini Pattarkine, J J. Tanner, C A. Bottoms, Y H. Lee, Judy D. Wall

Faculty Works

The structure of the type I tetraheme cytochrome c3 from Desulfovibrio desulfuricans G20 was determined to 1.5 A˚ by X-ray crystallography. In addition to the oxidized form, the structure of the molybdate-bound form of the protein was determined from oxidized crystals soaked in sodium molybdate. Only small structural shifts were obtained with metal binding, consistent with the remarkable structural stability of this protein. In vitro experiments with pure cytochrome showed that molybdate could oxidize the reduced cytochrome, although not as rapidly as U(VI) present as uranyl acetate. Alterations in the overall conformation and thermostability of the metal-oxidized protein were investigated …

Studies On The Formation Of Dna-Cationic Lipid Composite Films And Dna Hybridization In The Composites, Murali Sastry, Vidya Ramakrishnan, Mrunalini Pattarkine, Krishna N. Ganesh

Faculty Works

The formation of composite films of double-stranded DNA and cationic lipid molecules (octadecylamine, ODA) and the hybridization of complementary single-stranded DNA molecules in such composite films are demonstrated. The immobilization of DNA is accomplished by simple immersion of a thermally evaporated ODA film in the DNA solution at close to physiological pH. The entrapment of the DNA molecules in the cationic lipid film is dominated by attractive electrostatic interaction between the negatively charged phosphate backbone of the DNA molecules and the protonated amine molecules in the thermally evaporated film and has been quantified using quartz crystal microgravimetry (QCM). Fluorescence studies …

Hybridization Of Dna By Sequential Immobilization Of Oligonucleotides At The Air-Water Interface, Murali Sastry, Vidya Ramakrishnan, Mrunalini Pattarkine, Anand Gole, K. N. Ganesh

Faculty Works

The hybridization of DNA by sequential electrostatic and hydrogen-bonding immobilization of single-stranded complementary oligonucleotides at the air-water interface with cationic Langmuir monolayers is demonstrated. The complexation of the single-stranded DNA molecules with octadecylamine (ODA) Langmuir monolayers was followed in time by monitoring the pressure-area isotherms. A large (and slow) expansion of the ODA monolayer was observed during each stage of complexation in the following sequence: primary single-stranded DNA followed by complementary single-stranded DNA followed by the intercalator, ethidium bromide. Langmuir-Blodgett (LB) films of the ODA-DNA complex were formed on different substrates and characterized using quartz-crystal microgravimetry (QCM), Fourier transform infrared …
