    • Nutrition Guidelines and Childhood Obesity

      Gajonera, Kaycelyn Mhae; Langley, Jennifer; Macato, Cara (University of Alaska Anchorage, 2024-05-01)
      Problem According to the CDC, 1 in 7 children aged 2 to 5 have obesity, if this trend continues, by 2050 more than half of today's children and adolescents are projected to have obesity by the age 35 (CDC, 2022). Individuals with obesity are at an increased risk for major health problems later in life such as type 2 diabetes, fatty liver disease, hypertension, and myocardial infarction (Blüher, 2019). The Centers for Disease Control and Prevention established the Early Childcare and Education (ECE) that suggests school aged children between 6-12 years should consume lean meats, varieties of whole fruits, whole grain breads, cereals and pastas as seen in the CDC's nutrition standards (CDC, 2021). Research suggests that parental modeling and feeding practices are an important contributor in children's dietary habits and weight status (Martínez-Lacoba et al., 2018). A large number of studies regarding childhood obesity have strongly supported the use of the Mediterranean Diet as an effective way to combat the disease, however low adherence deters its' users from the therapeutic benefits and positive health outcomes (Tambalis et al., 2018). Gaps in Research Lack of knowledge regarding the combined influences of healthy body weight status determinants such as genetic, environmental, socioeconomic, and sociocultural factors, and their interactions (Kosti et al., 2020). Potential recall biases from self reporting questionnaires that hinders the true compliance of Mediterranean Diet, and assessment of life style interventions such as physical activity (Tambalis et al., 2018). Purpose The purpose of this evidence-based project is to explore the following PICO: (P) Population - Childhood Obesity (I) Intervention - Mediterranean Diet (C) Control - Not specific diet (O) Outcomes - BMI Nursing Theory & Evidence-Based Practice Florence Nightingale's Environmental Theory describes how environmental factors can greatly influence a person's health and therefore needs to be incorporated into the patient's care plan. It can be reasoned that such factors include sufficient food and appropriate nutrition (Petiprin, 2019). According to the Environmental Theory, it would be a priority for the patient to receive a diet that promotes good health. The IOWA Model of Evidence-Based Practice defines a priority based on problem-focused and knowledge-focused triggers. A couple of these triggers include identification of a clinical problem and new research or other literature. Methods to help reduce the incidence of childhood obesity through nutrition is a common clinical problem. There have been a number of studies that suggest the Mediterranean diet as a potential option to improve BMI in children and adolescents. Many of these research studies have produced positive results. Because the Mediterranean diet has produced positive outcomes in regard to obesity in the pediatric population, according to the IOWA Model, promotion of the diet as a viable nutritional intervention can be adopted into evidence-based practice.
    • H&H Exhibition: Bunnyson (2024)

      Gonzalez Mazo, Marina; Aoki, Miho (2024-04-04)
      Bunnyson is a charm worn as a necklace or an insignia. It is crafted in 14k gold and holds a 0.35 ct diamond with grey coloration and a pearl cut. The jewel was designed in Blender, a free and open-source software. I then printed the sculpture with the help of the 3D printers in the UAF Makers Space, using Polycast filament. A new plastic filament designed to burn without residue was meant to replace wax in the traditional casting process. I created my 14k gold alloy by mixing gold with copper, following the old Spanish jewelry tradition. This gives the gold a slight pinkish hue. The design features two bunnies facing each other, holding the diamond together with their paws. They sit on top of a heart shape and have wings on the side. I wanted the jewel to look like a coat of arms inspired by royal and religious insignias. A symbol of status and wealth. It is a soft and whimsical design, almost like it was from a fairytale. The rabbits make a consistent apparition in my BFA thesis show as I use them as a euphemism for sexuality and devotion. With this piece, I wanted to create an heirloom jewel that would hold my BFA show in a nutshell, a insignia for reaching my commencement as a professional artist.

Using water quality and water sample data, this poster offers insight into the current winter conditions of Happy Creek, and what these conditions imply for fish survival under the ice.
    • How does a permafrost lake influence downstream carbon cycling?

      Thomason, Iva; Kehoe, Paige; Johnston, Sarah Ellen (2024-04-04)
      The Arctic is warming at nearly twice the rate of the mid-latitudes. Due to this warming, there are drastic changes in the environment, including in waterways. Permafrost releases ancient organic carbon (OC) into the modern environment as it thaws in warming Arctic temperatures. This permafrost has been found to be highly available for microbes to decompose into CO2 and CH4 representing a positive climate feedback. By measuring the rate of biodegradable dissolved organic carbon (BDOC) consumption by microbes in lakes and streams around the Fairbanks area, we can assess the impact of seasonal changes and permafrost thaw on BDOC.
    • Extracting Ancient DNA From the North Slope

      Smith, BreAnna; Wolf, Diana (2024-04-04)
      Eight samples of ancient spruce DNA were found frozen on the North Slope. The samples are about 80,000-130,000 years old. 50,000 years ago, the North Slope was glaciated. We have successfully extracted DNA from 1 sample. We will conduct future extractions on the remaining samples and identify their species.

    • Phylogeography and Ploidy of Alaskan Labrador Tea (Rhododendron tomentosum and R. groenlandicum)

      Crawford, Denali; Phillips, James; Takebayashi, Naoki (2024-04-04)
      Our goal is to detect if there is a historical signature of gene flow in the sympatric area. Additionally, we will investigate if these two species are unable to interbreed due to ploidal differences in the populations where they coexist. In the future, the generated sequence data can be used to address demographic history of Rhododendron tomentosum and R. groenlandicum.
    • Do bulk nitrogen isotope ratios capture declines in captive muskox body condition?

      Cook, Molly; Savory, Garrett (2024-04-04)
      We were interested in studying muskox bulk nitrogen isotope ratios to see if these values capture declines in body condition. We were particularly interested in using archived serum from muskox at the University of Alaska Fairbanks Large Animal Research Station from 2009-2010 when there was a decline in the body condition of some individuals due to deficiency in trace minerals. Nitrogen isotope ratios can be analyzed to assess protein balance in animals. Since the lighter isotope of nitrogen (14N) is preferentially excreted in urine, the heavier isotope of nitrogen (15N) is enriched in tissues. As a result, we expect to see a decrease in N15 ratios when an animal is in a state of emaciation.
