Methods: First-year university students (n=265; 58 men, 205 women) were recruited through Facebook and email invitations to complete a 50-item survey. Survey categories included skills/confidence in food budgeting (8), meal planning (12), and cooking techniques 12); class interest (4), student background information (9), and general …

Effects Of Reproductive Maturity On Neuroplasticity In Male Bumble Bees (Bombus Impatiens), Karlee Eck

Undergraduate Honors Capstone Projects

Within the span of an insect's lifetime, new synaptic connections between neurons are made in response to age and experience. This neuroplasticity leads to anatomical changes within individual brain regions that represent investment in different brain functions. The neuroplasticity of female bumble bees has been well studied, but almost nothing is known about how the male bee brain responds to life experiences. Due to the complex sensory requirements of mate finding and copulation for males, neuroplasticity is likely to be an important component of reproduction. These sensory requirements include olfactory and optic inputs, which are processed in the calyces of …

Young Germ Cell Depleted Ovaries In Post-Reproductive Mice And Its Effects On Immune Function, Mckenna Walters

Undergraduate Honors Capstone Projects

It has previously been shown that young, cycling ovarian transplantation in aged female mice increased the general health and life span in regard to their post-reproductive health. It has further been hypothesized that this enhancement of health is directly influenced by the ovarian somatic cells. To address this hypothesis, transplants of young germ cell depleted and germ cell containing ovaries were performed on female mice. The purpose of this study is to continue to discern the reproductive influence on aging health, specifically in the area of immunological well-being. Control group mice were separated by age and treatment mice were subsequently …

Analyzing Fear Free Veterinary Practices And Their Effectiveness In Managing Client And Patient Fear, Anxiety, And Stress, And The Profitability Of These Techniques, Heather Hamblin

Undergraduate Honors Capstone Projects

Fear-Free veterinary techniques are a new approach to caring for patients and clients in the veterinary clinic that have gained a great deal of popularity and traction. However, many veterinary professionals are left to question whether the utilization of these practices is resulting in a big enough change in client and patient stress levels to make it worth implementing these methods. This research looks into the views of veterinarians and clients on the effectiveness of these practices, and the competitive advantage of having a fear-free certified clinic from a business point of view.

The Effect Of A Surfactant Seed Coating On The Germination And Growth Of Three Native Bulrushes, Anders Hart

Undergraduate Honors Capstone Projects

Great Salt Lake (GSL) wetlands provide vital ecosystem services, including habitat for migratory birds. Alkali bulrush (Bolboschoenus maritimus), hardstem bulrush (Schoenoplectus acutus), and three-square bulrush (Schoenoplectus americanus) play an important role in providing these services, but invasion by Phragmites australis has reduced the extent these species in GSL wetlands. Restoring these native bulrushes following Phragmites removal is a primary goal for GSL managers. However, climate change and increasing human water demands upstream may alter the hydropattem of GSL wetlands, leading to lower soil moisture availability and potentially inhibiting germination and establishment of these species. …

Fermentation Of Prebiotics In Whole Food Powders By Probiotic Lactic-Acid Producing Bacterial Strains To Identify Synbiotic Combinations, Michaela Brubaker

Undergraduate Honors Capstone Projects

Dietary interventions with probiotic lactic acid bacteria (LAB) and prebiotics, complex dietary fibers that promote LAB growth, may favorably shift the gut microbiome to reduce colorectal cancer risk. Our primary hypothesis was that the LAB strains NCFM Lactobacillus acidophilus and HNO 19 Bifidobacterium lactis would thrive in the presence of agave, green banana, black raspberry, baobab fruit, or pomegranate peel whole food powders by fermenting their oligosaccharide (OS) components into lactic acid end products. LAB strains were cultured in media with no carbohydrate, purified OS, or one of the whole food powders. LAB strains cultured with agave appeared to grow …

Percussive Behavior In The Southern Resident Killer Whale (Orcinus Orca) Population At Lime Kiln Point State Park, Rylee Jensen

Undergraduate Honors Capstone Projects

The endangered Southern Resident Killer Whale (Orcinus orca, SRKW) is an iconic species in the Pacific Northwest. Although many ecological aspects of this population have been studied, including population dynamics, genealogy, diet, and habitat-use patterns, why SRKW perform above-surface "percussive" behavior such as breaching, cartwheeling, pectoral fin slapping, tail lobbing, and dorsal fin slapping remains unclear. In the present study, a) individual percussive behavioral data was recorded during the summer of 2016 to evaluate trends by age and sex class, and b) an existing long-term data set on SRKW was analyzed to compare the relationship between the seasonal …

Evaluating The Potential Of Repurposing Commercially Available Drugs For The Treatment Of Viral Infections, Brennan Connor Mcewan

Undergraduate Honors Capstone Projects

Viral infections that are often overlooked as common seasonal illnesses such as influenza can rapidly become a public threat. They threaten society as new, more dangerous strains of these common viruses emerge and as strains develop resistance to current vaccines and antiviral treatments (Kochanek, Murphy, Xu, & Tejada-Vera, 2014). To combat this, the development of antiviral treatments with novel mechanisms of action is essential. Repurposing drugs instead of developing new drugs can save years of development time and hundreds of millions of dollars (DiMasi, Hansen, & Grabowski, 2003). To support the effort to discover drugs with unique mechanisms of action, …

Manipulation Of Ovarian Function Significantly Influenced Glucose Metabolism In Cba/J Mice, Kyleigh Ann Tyler

Undergraduate Honors Capstone Projects

Menopause is associated with a decline in overall health in women. One health aspect impacted is glucose metabolism. As women experience menopause, their metabolism declines dramatically. The current study addressed the influence of ovarian somatic cells on the improvement of metabolic health through transplantations of young, germ cell-depleted ovaries. The purpose of this study is to expand the understanding of female reproductive health on metabolism. Control mice were grouped by age and treatment mice were age-matched. Treatment mice were placed into one of three groups: 1) mice received germ cell-depleted ovaries, 2) mice received germ cell-containing ovaries, and 3) mice …

Transcriptomic Analysis Of Honey Bees Exposed To Organosilicone, Matthew Brent Thompson

Undergraduate Honors Capstone Projects

Honey bees play an important role in agriculture and the decline of honey bee populations worldwide has generated concern. While the application of pesticides in agricultural settings is often implicated in the deterioration of honey bee population health, pesticide applications contain more than just pesticides; they also contain adjuvants that may have detrimental effects to bee health. One known effect of one type of adjuvant is the suppression of immunity-related genes and consequent increase of viral load in larvae. We investigate the effects of one class of adjuvant, organosilicone surfactants (OSS), on adult honey bee health. In a laboratory based …

A Review Of Osteoarthritis, Madelin Brooke Session

Undergraduate Honors Capstone Projects

Osteoarthritis is a degenerative joint disease which plagues many older animals and humans. It is a disease that is characterized by the degeneration of joint cartilage, inflammation, as well as chronic pain and stiffness that results from this disorder. Unfortunately, most of the treatments for this painful and chronic disease mostly involve pain management and temporary relief strategies. These strategies usually include pain medication, non-steroidal anti-inflammatory drugs, injectable lubricants, as well as surgical techniques. However, because these treatments are just temporary fixes meant for pain management and to improve quality of life they must continue throughout the remainder of the …
