Short and Long Term Effects of Antibiotic Treatment on Mitochondrial Membrane Potential and Proliferation of HEK293 Cells

Rhiannon Red Bird, Biological Sciences Undergraduate Student

College of Natural Resources & Sciences

Antibiotics are commonly used in modern-day cell culture to prevent the loss of valuable data and cells- useful for protecting valuable cells during long-term studies. Cells are cultured in nutrient rich media, causing rapid proliferation of unwanted contaminants (i.e. viruses/ bacteria). We know that short term treatment negatively affects cell differentiation, proliferation, regulation and metabolism- yet, are still commonly used in cell culture. In this study, we cross-examined the effects of short term antibiotic treatments (96 hours) and long term antibiotic treatments (192 hours) on human embryonic kidney cell proliferation, mitochondrial membrane potential, and protein expression.

Sorrel Leaf Healing Center Mental Health 101 Training and Coping Skills Toolbox

Ashly Kloiber, Social Work Graduate Student

College of Professional Studies

This project consisted of two deliverables. The first is a digital Canva presentation that will educate Sorrel Leaf Healing Center non-clinical staff on the basic neuroscience behind trauma and how trauma connects to behavior and diagnosis, in addition to addressing cultural considerations and incorporating mental health first aid concepts. The second deliverable is a toolbox that provides coping skills interventions for staff to use with residents that assist with co-regulation.

Soulmates within Primates

Michael Szyndler, Anthropology Undergraduate Student

College of Arts, Humanities & Social Sciences

This Poster is about the potential future research within the primatology field, specifically within the studies of pair bonding between Titi monkeys, Owl monkeys, and Gibbons. This project shows the conclusive evidence of pair bonding done already and what it entails and what the outcomes are. The project also includes information on these species as well as a breakdown of what pair bonding is and why it is important.

Spectral Analysis of Currents in Humboldt Bay

Taylor Juchau, Oceanography Undergraduate Student

College of Natural Resources & Sciences

Our purpose is to analyze the ADCP (Acoustic Doppler Current Profiler) data from the PORTS Hookton Channel Day Marker 3 station in Humboldt Bay, CA, to compare with the analysis of the ADCP data at the PORTS Chevron Pier station done by Emma Modrick and Isabelle Marcus (Modrick et al., 2022). We want to determine the proportion that each tidal component makes to the mixed semidiurnal tides in the bay, by looking at the dominant frequencies in the tidal currents. We will then compare our results with those of Modrick and Marcus, as well as with the published results of the National Oceanic and Atmospheric Administration (NOAA).

Spotted Banana Slugs, Ariolimax columbianus, and Canopy Cover

Sasha Milstein, Wildlife Undergraduate Student

College of Natural Resources & Sciences

Numerous animal species display diverse colorations as a means of performing cryptic coloration, which protects them from predation. In the case of banana slugs, some individuals exhibit monochromatic hues, while others display spots. The purpose of my study was to answer if some banana slugs are spotted to perform cryptic coloration as a means of anti-predator defense.

Strategies to Lower Risk in the Management of Acute Aggression

Luz Gomez, School of Applied Health Undergraduate Student

College of Professional Studies

Acute aggression poses a risk of harm to patients and staff in acute care. On one hand, disparities in the management of aggression are well documented, with factors like race affecting the likelihood of restraint use. However, agitation is also a leading cause of staff injury, with the majority of such injuries occurring during the application of restraints. Using the Model for Evidence-Based Practice Change, this project aims to implement an aggression order set modeled after the Project BETA (Best Practices in the Evaluation and Treatment of Agitation) guidelines. With this approach, duration of restraint application and incidence of staff injury will decrease by 50% over the next year.

Summative Evaluation for Cal Poly Humboldt's 2022 Summer Algebra Institute

Rose Francia, Education Staff

Other

For the second consecutive summer, Cal Poly Humboldt's CSU Summer Algebra Institute's (SAI) goal was aimed at demystifying Science, Technology, Engineering, Arts, and Mathematics (STEAM) related projects, majors, and careers, to further increase Humboldt, Del Norte, and Mendocino County BIPOC (6th-12th grades) students’ interests in pursuing majors and careers in STEAM, and minimize learning gaps in mathematics. Students who enrolled in the virtual 2022 SAI, a 4-week program, completed a minimum of 57 hour intensive individualized Mathematics course using EdReady, engaged in 19 days of culturally relevant STEAM curriculum, and participated in workshops on College & Career Preparation.

Surgical Smoke: The Forgotten Biohazard

Julie Wooldridge, School of Applied Health Undergraduate Student

College of Professional Studies

Surgical smoke, a byproduct of surgical procedures, poses significant health risks to healthcare workers and patients. However, surgical staff often overlook it as a biohazard in operating rooms. This project highlights the harmful toxins of surgical smoke, including exposure to carcinogens and infectious agents, and the need for policy change to mandate local smoke evacuation. Effective policies and guidelines for smoke evacuation modeled from evidence-based research, combined with adequate education, awareness, and training, can minimize the risks of surgical smoke in the operating room and empower nurse leaders to ensure the safety of healthcare workers and patients.

Sustainability in Mental Health

Meghan Stanton, Social Work Graduate Student

College of Professional Studies

Our community project has been multifaceted as there are several issues impacting Semper Virens. We have been focusing on identifying ways to utilize the physical environment of Semper Virens in more therapeutic ways that would also be more welcoming and nurturing for the clients as well as more positive for the staff. We have simultaneously been developing workbooks of complementary exercises and activities aimed at improving mental health, wellness, and selfcare. The workbooks contain a variety of approaches including one specifically adapted for Native Americans.

Temporal changes in body conditions of wintering waterfowl in Humboldt Bay

Amir Malikyar, Wildlife Undergraduate Student

College of Natural Resources & Sciences

Overwintering migratory birds may face increased competition for resources than in other seasons due to large influxes of birds arriving and inhabiting shared areas for similar amounts of time. These mechanisms may affect food availability, which in turn is implied to affect body energy reserves. We conducted a study to determine the temporal effects of body conditions of hunted waterfowl carcasses in Humboldt Bay, California, and test whether energy reserves as functions of body condition indices decrease over the winter season.
