Efficacy And Benefits Of Providing A Screening Clinic For Performing Arts Students, Shaun Bean, Joanna Centeno, Elizabeth Williams

UNLV Theses, Dissertations, Professional Papers, and Capstones

In past years, University of Nevada, Las Vegas physical therapy students (UNLVPT) have provided UNLV dance students with screening clinics, injury evaluations, and treatment sessions to help address their need for direct and specialized services. Through this project, UNLVPT has worked to help reduce injury risk in dancers and provided treatment and rehabilitation for injuries that have occurred. Due to the COVID-19 pandemic, our group was unable to treat dancers in person over the course of the 2020-2021 school year. In response to these limitations, we worked to reformat our screening process to make it practical in a virtual setting. …

Research Report: High Tunnel Tomato Fruit Cluster Pruning, Caterina Roman, Rebecca G. Sideman

Faculty Publications

Tomatoes are a high value crop grown worldwide. Indeterminate varieties are commonly grown in high tunnel structures throughout New England for the fresh market. Indeterminate tomato plants often suffer from a phenomenon called ‘June drop’ in which the plant’s first four to five cluster of fruit set perfectly but the subsequent two to three clusters have poor set and plant productivity drops suddenly. While cluster thinning (e.g., reducing the number of fruit allowed to mature per cluster) has been successfully shown to increase fruit size, it has generally not increased marketable yield. We hypothesized that reducing the fruit load by …

Modeling Leaf Area Index And Canopy Height Using Growing Degree Days, Ellie J. Kuhn

Biological and Agricultural Engineering Undergraduate Honors Theses

As the global population increases and food security is recognized as a critical issue, crop growth prediction models help ensure the sustainability of reliable food sources. Using a prediction model based on temperature and simple, measurable field parameters, e.g., Leaf Area Index (LAI) or Canopy Height (H_can), may allow farmers and others to intervene mid-season with fertilizer, irrigation, or other inputs to obtain a better harvest.

This study aims to create a general model that could predict LAI and H_can values for numerous rice varieties using Growing Degree Days (GDD) as the time scale. The models use …

Potato Processing In The Home: Sustainability And Nutritional Impacts, Aubin Payne

Biological and Agricultural Engineering Undergraduate Honors Theses

Potatoes are the world's fourth most consumed crop. Their versatility and long shelf-life make them a staple food for millions of people worldwide. Still, the increasing consumption of highly processed potato products in developed countries has damaged the public's appreciation of potatoes as a valuable source of essential nutrients. Additionally, as public awareness of environmental sustainability increases, the average consumer is more likely to value processing methods that mitigate environmental damage.

Researchers simulated several home storage and processing conditions to find out how nutrition and environmental impact are affected by the home processing timeline. Then, a nutrient analysis, life cycle …

Sensory Comparison Of Beer Carbonated Using Forced Carbonation And The Carbo Rock-It, Michala Smith

Biological and Agricultural Engineering Undergraduate Honors Theses

Craft brewing is a growing market which represents over 12% of beer produced in the United States. Dr. G Scott Osborn, PE invented the Carbo Rock-It™ to improve the carbonation process for craft breweries. The invention allows for shorter carbonation time and uses less CO₂, saving companies money and time. Because of the lack of gas losses through bubbling, Osborn theorized that the Carbo Rock-It could also prevent the “stripping of the nose” that can occur in traditional forced carbonation. Existing research supports the mechanism, as beer flavor and aroma volatiles have been detected during the release of …

Anxiety And Immunity: Affecting The Body And The Mind, Katelynn Dobbs

Theses/Capstones/Creative Projects

Speculations have been made within the scientific community that there is a link between the underlying mechanisms that impact anxiety disorders and immune system disorders. While many correlations between these disorders have been observed through various immune system disorder studies, this subject is still severely under-explored. In order to examine the potential relationship between anxiety disorders and immune system disorders, a survey was conducted and distributed among the student population at the University of Nebraska at Omaha. This survey collected data by asking a variety of questions that pertained to anxiety and immune system disorders diagnoses within the student population …

Identification Of Synonymous Genes And Pathways Implicated In Irritable Bowel Disease And Pancreatic Duct Adenocarcinoma, Lavanya Uppala

Theses/Capstones/Creative Projects

Better understanding and genetic characterization of the gut microbiome will allow for the identification of clinically distinct gastrointestinal diseases. Facilitated by high throughput technologies, intestinal flora analyses have elucidated a broad spectrum of neuropsychiatric, immunological, and allergic disorders linked with this organ system. Microbiome research especially has shed light on underlying factors of intestinal disorders. This interplay of environmental bacteria versus host tissue gene expression may have implications for disease pathogenicity and etiological determination. For instance, pancreatic disorders are common symptoms of irritable bowel disease (IBD), which is thought to affect approximately 7% to 21% of the population [1]. However, …

Diagnostic Utility Of Red Cell Indices In Relation To Serum Iron Indices For Evaluation Of Iron Deficiency In Heart Failure, Larry Wangai Mburu

Master of Medicine in Internal Medicine

Background: Iron deficiency (ID) in heart failure (HF) causes poorer outcomes, and evaluation using ferritin and transferrin saturation (TSAT) in our setting is hampered by cost and availability. Though the red cell indices (RCIs), routinely used for assessment of ID anaemia, have shown utility in predicting outcomes in HF, they have not been evaluated in this population for prediction of ID relative to the iron indices. A combination of the RCIs, the combined cell index (CCI), may be more accurate. Validating the diagnostic accuracy of the RCIs would improve evaluation of ID in low-resource settings and improve uptake of iron …

Healthy Diet Affordability In North Alabama During Covid-19, Nicholas Knighten

Perpetua: The Journal of Undergraduate Research at UAH

Previous research has shown that nutrient dense, low-calorie foods are bought at higher rates by those with higher incomes. 1 These types of studies have engulfed common knowledge on healthy diet affordability. However, a recent study of the Mechoopda Indian Tribe of Chico, California, found a healthy diet filled with popular foods can be afforded by all members of the community.2 By focusing on healthy foods people want to eat and their localized affordability, research applicability in policy clearly increases. This study uses a framework similar to the California study while tweaking a few aspects to better suit a more …

Exercise Counteracts The Deleterious Effects Of Cancer Cachexia, Stavroula Tsitkanou, Kevin A. Murach, Tyrone Washington, Nicholas P. Greene

Health, Human Performance and Recreation Faculty Publications and Presentations

Cancer cachexia (CC) is a multifactorial syndrome characterised by unintentional loss of body weight and muscle mass in patients with cancer. The major hallmarks associated with CC development and progression include imbalanced protein turnover, inflammatory signalling, mitochondrial dysfunction and satellite cell dysregulation. So far, there is no effective treatment to counteract muscle wasting in patients with CC. Exercise training has been proposed as a potential therapeutic approach for CC. This review provides an overview of the effects of exercise training in CC-related mechanisms as well as how factors such as cancer comorbidities, exercise modality and biological sex can influence exercise …

A Broken Market: Can Increased Access To Broken Rice Decrease Food Insecurity In Haiti?, Matthew Greer Richardson, Lawton L. Nalley, Alvaro Durand-Morat, Philip G. Crandall, Andrew Scruggs, Lesly Joseph, Jerome Chouloute, Wei Yang

Food Science Faculty Publications and Presentations

Haiti is a unique rice market in the sense that, despite the high poverty rates and dependency on rice as a staple, it relies on imports (80% of total consumption) of high-quality milled rice for which it pays a premium price. Haiti requires that all imported rice have a maximum of 4% broken kernels, which results in Haiti importing one of the most expensive non-fragrant long grain rice in the world. This study implements a non-hypothetical field experiment (300 observations) to elicit which rice attributes Haitians valued as revealed by their purchasing behavior in an open-air market setting. Specifically, we …

What Socioeconomic Factors Influence Breastfeeding Rates?, Keely Ford

Senior Honors Projects

The American Academy of Pediatricians recommends exclusively breastfeeding for six months due to breast milk's nutritional value and protection against various long term and short-term illnesses. Children who are exclusively breastfed for six months have reduced rates of asthma, obesity, type 1 diabetes, severe lower respiratory disease, acute otitis media, sudden infant death syndrome, gastrointestinal infections, and necrotizing enterocolitis in premature infants. The CDC’s most recent national immunizations study, observing infants born in 2018, discovered that only 56.7% of infants were being breastfed at six months and not exclusively. And only 25.8% of infants born in 2018 were breastfed exclusively …

The effect of cortisol on abdominal fat accumulation

Sponsor: Brietta Oaks (Nutrition)

Cortisol is the stress hormone of the body, it increases sugars in the bloodstream, enhances the brain's use of glucose, and increases the availability of substances to repair tissues. A healthy person has a daily slope of cortisol where it is high when they wake up and then decreases throughout the day. Cortisol, however, can be high throughout the day for people who live stressful or unhealthy lives. There have been conversations that high cortisol can cause fat gain specifically in the abdominal area. …

Senior Honors Projects

University dining halls are understudied food environments that affect student diet quality. This study (1) assessed dining hall offerings at the University of Rhode Island (URI) using the Partnership for a Healthier America’s Healthier Campus Initiative (PAHA) criteria for healthier campus food environments and (2) evaluated student perceptions of the dining hall through a campus-wide survey (n=165). We evaluated breakfast, lunch, and dinner using spring cycle menus (16 weeks in 2019 and 4 in 2021) from two full-service dining halls totaling 29 meals in 2019, and 84 meals in 2021 to determine adherence with PAHA criteria for availability of: 1) …

Nutrition In Uri Athletes Vs. Non-Athletes, Amity Tobias

Senior Honors Projects

Being a student athlete and growing up in sports has had both positive and negative effects on my life. Children often take part in sports at a young age to teach them important life skills such as dedication, hard work, and discipline. While sports are very effective for physical fitness and being a part of a team may be crucial in a kid’s life, there may also be some negative effects. Some sports such as gymnastics, hockey, soccer, etc., have an intensely high demand, both physically and mentally. Athletes are stereotyped to be the fittest, healthiest group of people and …

Gastrointestinal Alterations In Two Mouse Models Associated With Social Behavior Deficits, Gracie Leamon

Undergraduate Honors Theses

The gastrointestinal (GI) tract is a diverse habitat for multiple microorganisms. Disturbances in the microbiome of the GI tract have been associated with psychiatric disorders including autism spectrum disorder (ASD). Individuals with ASD, when compared to neurotypical individuals, have demonstrated differing gut species. Also, it has been shown that microbial transplant therapies impact ASD symptoms in patients. Animal models of behaviors associated with ASD might offer insight for the actual role these microbial differences may occupy regarding symptoms. Unfortunately, ASD does not have an accepted animal model where the GI alterations have been thoroughly explored. In this study, we sought …

The Fecal Fermentation Profile Of Infants With Different Feeding Modalities, Willow Lewis, Michelle E. Johnson, William A. Clark, Amy Wahlquist

Undergraduate Honors Theses

Introduction/Background

Research indicates nutrition and environment in the first year of a child's life are crucial in their development and growth and can contribute to lower chances of developing obesity and other health concerns. Key factors that can determine these outcomes include the bacteria and resulting short chain fatty acids (SCFAs) present in the gut. This composition may be affected by feeding modality (formula feeding vs breastfeeding), exposure to the mother’s microbiota, weight status of the child, and type of delivery. This research aims to identify the impact of infant feeding modality on toddlers' fecal fermentation profile, and if there …

An Assessment Evaluating The Possible Participation Of A Virtual Nutrition Education Program For Older Adults, Ashlyn Cobble

Undergraduate Honors Theses

The importance of proper nutrition education among older adults is crucial in promoting overall physical health and management of chronic health conditions. However, access to such education has been limited, especially during the COVID-19 pandemic. With the current boom in social media popularity, as well as virtual communication portals such as Zoom, the question must be asked if nutrition education could be effectively implemented for the use of older adults through these electronic channels. The study design for this particular research was a cross sectional survey to inform development of an online nutrition education program for older adults in Northeast …

Severe Hypoxia Up-Regulates Gluconeogenesis In Daphnia, Morad C. Malek

Undergraduate Honors Theses

Hypoxia is a significant low oxygen state that has complex and diverse impacts on organisms. In aerobes, various adaptive responses to hypoxia are observed that vary depending on the level of oxygen depletion and previous adaptation, hence the continued attention to hypoxia as an important abiotic stressor. Adaptive responses to hypoxia are primarily governed by the hypoxia-inducible factors (HIFs), which activate downstream genetic pathways responsible for oxygen transport and metabolic plasticity. In aquatic habitats, oxygen availability can vary greatly over time and space. Therefore, aquatic organisms’ adaptation to hypoxia is likely pervasive, especially in genotypes originating from waterbodies prone to …

Identification Of Genetic Elements Involved In Alcaligenes Faecalis’ Inhibitory Mechanism Against Polymicrobial Species, Abigail Mathis

Undergraduate Honors Theses

The rise of antibiotic resistance in common human pathogens and the lack of development of novel therapeutic treatments has created a threat to global health. A unique source for potential novel treatments are from microorganisms, particularly within the complex, antagonistic polymicrobial interactions that take place in microbial communities. These unique mechanisms utilized by microorganisms to fight each other could potentially identify novel therapeutic targets for use at a clinical level, however, there is a lack of research in this area to determine its applicability. Alcaligenes faecalis is a Gram-negative bacterium that seldom causes human disease and has been observed in …

Teaching Old Calipers New Tricks: Using Craniometrics For Ancestry Admixture Estimation Via Fuzzy Math, Kristi Carnahan

Master's Theses

Cranial measurements have been a cornerstone of physical anthropology since its formation as a discipline in the early 1900s. However, most other ancestry determination methods come with a significant epistemological issue: they differentiate individuals into discrete categories without accounting for the issue of admixture. Advances in data mining and analysis techniques can now be used to help resolve this issue through soft computing, also known as “fuzzy math”. This type of advanced computational math requires specialized knowledge in computer programming, statistics, and data analysis techniques unless one is using computer programs specially designed to run these analyses.

Children’s Nutrition Research Center Staff Publications

Sustainability of intervention programming is challenging to achieve under real world conditions, since few models exist and many studies do not plan far beyond the funding period. Programming content in early care and education centers (ECECs) is often driven by guidelines. However, implementation is very sensitive to contextual factors, such as the setting and implementer (teacher) characteristics. This paper presents the model, definitions, and methodology used for the sustainability action plan capitalizing on a community-based participatory research (CBPR) approach, developed for a multi-site, multi-level garden-based childhood obesity prevention study, Sustainability via Active Garden Education (SAGE). The Ecologic Model of Obesity …
