The Association Between College Age Students' Nutrition Intake And Depression, Mackenzie Allen

Honors Projects

The research performed was to determine a correlation between depression and nutrient intake in college age students. This study used NHANES publicily available data and IBM's SPSS statistical software to analyze a correlation between depression and nutrition/lifestyle variables: vitamin D, vitamin B12, saturated fatty acids, unsaturated fatty acids, fiber, and exercise. The study found that fiber and unsaturated fatty acid intake had a negative correlation with depression, meaning that as the intake of these nutrients increased, depression decreased. This research reveals key factors to improve the nutritional status of college age students, along with their emotional wellbeing.

Phenotypic And Target-Based Drug Discovery, Angelica Veronica Carmona

Theses & Dissertations

Batten Disease or Neuronal Ceroid Lipofuscinosis (NCL) is a group of rare, fatal, inherited pediatric neurodegenerative lysosomal storage disorders. NCLs are characterized by intracellular accumulation of an auto-fluorescent lipopigment called ceroid lipofuscin and neurodegeneration. Several forms of NCLs exist, some of which share some of the same features and symptoms but vary in severity and onset of symptoms with respect to age. Some common symptoms include progressive loss of vision, mental and motor deterioration, epileptic seizures, premature death, and in the rare adult-onset, dementia. Subtypes of NCLs occur when one of 13 different genes are mutated, and only two subtypes …

Groundwater-Stream Connections Shape The Spatial Pattern And Rates Of Aquatic Metabolism, Anna Lupon, Lluís Gomez-Gener, Megan Fork, Hjalmar Laudon, Eugènia Martí, William Lidberg, Ryan A. Sponseller

Biology Faculty Publications

A longstanding challenge in stream ecology is to understand how landscape configuration organizes spatial patterns of ecosystem function via lateral groundwater connections. We combined laboratory bioassays and field additions of a metabolic tracer (resazurin) to test how groundwater-stream confluences, or "discrete riparian inflow points " (DRIPs), regulate heterotrophic microbial activity along a boreal stream. We hypothesized that DRIPs shape spatial patterns and rates of aquatic heterotrophic microbial activity by supplying labile dissolved organic matter (DOM) to streams. Laboratory bioassays showed that the potential influence of DRIPs on heterotrophic activity varied spatially and temporally, and was related to their DOM content …

Interactive Effects Of Climate Change‐Induced Range Shifts And Wind Energy Development On Future Economic Conditions Of The Atlantic Surfclam Fishery, Stephanie Stromp, Andrew M. Scheld, John M. Klinck, Daphne M. Munroe, Eric N. Powell, Roger Mann, Sarah Borsetti, Eileen E. Hofmann

Faculty Publications

Rising water temperatures along the northeastern U.S. continental shelf have resulted in an offshore range shift of the Atlantic surfclam Spisula solidissima to waters still occupied by ocean quahogs Arctica islandica. Fishers presently are prohibited from landing both Atlantic surfclams and ocean quahogs in the same catch, thus limiting fishing to locations where the target species can be sorted on deck. Wind energy development on and around the fishing grounds will further restrict the fishery. A spatially explicit model of the Atlantic surfclam fishery (Spatially Explicit Fishery Economics Simulator) has the ability to simulate the consequences of fishery displacement …

Mutating Tetur02g09850 Originated From Spider Mites To Enhance Crystallization, Hayley Cash

Senior Theses

This study aimed to explain and adequately utilize several common biochemical laboratory techniques to mutate a portion of the nucleic acid sequence within a specific protein. This protein, referred to as Tetur02g09850 is originated from Tetranychus Urticae, or the Two-Spotted Spider Mite. This mite causes excessive damage to crops and is known to be extremely resistant to most common pesticides. For this reason, understanding the protein structure could be used to explain this acaricide resistance and aid in the development of more effective pesticides. Some of the testing utilized was site-directed mutagenesis, IMAC and gel filtration for protein purification, gel …

Alfred Russel Wallace Notes 25. Wallace And The 'Physical Environment'., Charles H. Smith

Faculty/Staff Personal Papers

Alfred Russel Wallace’s natural selection essay of 1858 has been held to frame a greater role for the physical environment in forcing selection regimes than we find in Darwin’s writings, but here that verdict is challenged by a re-examination of both the essay itself, and period usage of the term ‘physical.’

Modulatory Roles Of Human Adenovirus Type 3 In Extracellular Vesicle Development, Trafficking, And Inhibition, Ayodeji Oludare Ipinmoroti

Dissertations

Respiratory human adenovirus (HAdV) has been closely linked with acute respiratory infections such as pharyngitis and coryza (common cold). While some HAdV serotypes antagonize the immune system leading to meningitis, gastroenteritis, and acute hemorrhagic cystitis among other conditions, HAdV type 3 (HAdV3) predominantly infects the upper respiratory tract. Studies have shown that the release of small, membrane-derived extracellular vesicles (EVs), termed exosomes, may offer a mechanism by which certain viruses, enter cells via receptor-independent entry. EVs play a major role in both cellular homeostasis and intercellular communication under both healthy and pathological conditions. Firstly, in this study, we demonstrated that …

Effect Of Action Selection Demands On The Execution Of Goal-Directed Reaches, James Garrison Riedy

Theses and Dissertations

A well-studied model of cognitive motor function is the process of action selection. It is unclear how the planning demands of a reaching movement interact with the added complexity of s election. Therefore, this thesis investigated the effect of adding selection demands to the performance of skilled reaches in a virtual environment. Thirty young, healthy participants reached ipsilaterally or contralaterally with either their dominant (right hand) or non-dominant (left hand) under two conditions: execute only (EO) and action selection (AS). Selection accuracy was higher for the EO condition than the AS condition for both arms and both directions (left arm: …

Watermelon produces many byproducts (watermelon rind and skin) even though those components contain various bioactive compounds, including citrulline. This study evaluated the citrulline concentration, total phenolic content, and antioxidant activity (DPPH and FRAP assays) of different parts of watermelon and investigated the bioavailability of citrulline from different parts of watermelon using an in vitro human intestinal epithelial Caco-2 cell monolayer model. Solid-phase extracted watermelon flesh, rind, and skin samples were treated on a Caco-2 cell monolayer for 1, 2, and 4 h. The collected basolateral solution at each time point was analyzed for the percentage of citrulline transport. Watermelon flesh …

Challenges In Forecasting Antimicrobial Resistance, Sen Pei, Seth Blumberg, Jaime Cascante Vega, Tal Robin, Yue Zhang, Richard J. Medford, Bijaya Adhikari, Jeffrey Shaman

Research on Antimicrobial Resistance

Antimicrobial resistance is a major threat to human health. Since the 2000s, computational tools for predicting infectious diseases have been greatly advanced; however, efforts to develop real-time forecasting models for antimicrobial-resistant organisms (AMROs) have been absent. In this perspective, we discuss the utility of AMRO forecasting at different scales, highlight the challenges in this field, and suggest future research priorities. We also discuss challenges in scientific understanding, access to high-quality data, model calibration, and implementation and evaluation of forecasting models. We further highlight the need to initiate research on AMRO forecasting using currently available data and resources to galvanize the …

Simulating A Flexible Water Model As Rigid: Best Practices And Lessons Learned, Raymond Weldon, Feng Wang

Chemistry & Biochemistry Faculty Publications and Presentations

Two ways to create rigid versions of flexible models are explored. The rigid model can assume the Model’s Geometry (MG) as if the molecule is not interacting with any other molecules or the ensemble averaged geometry (EG) under a particular thermodynamic condition. Although the MG model is more straightforward to create, it leads to relatively poor performance. The EG model behaves similarly to the corresponding flexible model (the FL model) and, in some cases, agrees even better with experiments. While the difference between the EG and the FL models is mostly a result of flexibility, the MG and EG models …
