Characterizing The Role Of Pa5189 Of Pseudomonas Aeruginosa In Deletion And Overexpression Mutants, Seh Na Mellick
Characterizing The Role Of Pa5189 Of Pseudomonas Aeruginosa In Deletion And Overexpression Mutants, Seh Na Mellick
Theses/Capstones/Creative Projects
In the context of rising multidrug resistance in biofilm-forming pathogens like Pseudomonas aeruginosa, this study investigates the role of the understudied transcription factor PA5189 in antibiotic resistance and biofilm formation. PA5189 deletion and overexpression mutants were created in a parent P. aeruginosa strain using pEX18Tc-based recombinant suicide vectors, with genotypic verification of putative triparental conjugants achieved through restriction digestion and PCR. The study revealed that PA5189 overexpression significantly increases resistance to commonly used broad spectrum antibiotics such as ciprofloxacin and imipenem. Additionally, differential expression of PA5189 was found to notably affect biofilm formation, with variations contingent on the nutrient …

Effects Various Distilled Water Brands Have On Chlorophytum Comosum., Brooke Bluhm
Theses/Capstones/Creative Projects
When first attempting home gardening, one of the challenges many home-renters are starting to face is being able to supply enough clean water to one’s plants. In order to overcome this challenge, many plant enthusiasts are utilizing prepackaged distilled water from price friendly brands available at most regional Walmart locations. With the number of choices available on the shelves of today’s grocery stores, and vague ingredient lists on packaging it can be challenging to determine which brand is actually best suited for one’s specific needs. In order to determine the best distilled water suited to grow Chlorophytum comosum, various gallons …
Analysis Of Water Pollutants Across Greater Omaha, Desmond Marshall
Analysis Of Water Pollutants Across Greater Omaha, Desmond Marshall
Theses/Capstones/Creative Projects
Water is a finite resource, and most water has the potential to become contaminated in sitting bodies. Health complications have an increased chance of occurring when these water sources have pollutants. Preventative and treatment methods are components of the legislation put in place to prevent concentrations from reaching levels capable of causing these ailments. However, sites sometimes fail to keep them under tolerated levels. This study is intended to examine if several locations across Omaha are keeping pollutants under legal concentrations and analyze any trends in the data. Locations (n=10) are sampled twice, with exactly two-weeks between collections. The water …

Optimization Of Tyrosine Hydroxylase Antibody For Immunohistochemistry Fluorescence Detection In Zebrafish (Danio Rerio), Madison Thurber
Theses/Capstones/Creative Projects
Dopamine is an important neurotransmitter produced through the catecholamine synthesis pathway that affects brain activity. Unregulated dopamine levels can lead to various diseases such as Parkinson’s Disease or attention deficit hyperactivity disorder (ADHD). Optimization of an immunohistochemistry protocol will allow for the quantification of tyrosine hydroxylase antibody, which indirectly allows for dopamine quantification in dopaminergic regions within the brain. However, the antibody concentration to give the optimal signal-to-noise ratio in IHC varies across studies. Through this experiment, I determined the concentration of tyrosine hydroxylase (TyrH) antibody for immunohistochemistry that gave the best signal-to-background noise ratio within several known dopaminergic regions …

A Phylogenetic Analysis Of The Population Dynamics Of A Captive Colony Of Diploptera Punctata., Nick Peterson
Theses/Capstones/Creative Projects
The unique milk production of Diploptera punctata makes this species a promising model species in entomology for studying the evolution of milk production and for insect endocrinology. Despite this, the genetic diversity of captive populations of the species is not well studied. To better evaluate the captive diversity and population dynamics of Diploptera punctata at UNO we extracted the DNA of 20 random individuals and amplified their DNA using 4 different primers before cleaning the amplified products and sequencing the genes of the samples for use in both individual and concatenated phylogenetic trees. Our results indicate the UNO colony of …
The Effect Of An Oak Savanna Habitat Restoration On Bat Activity In Eastern Nebraska, Aidan Hatfield, Jeremy White
The Effect Of An Oak Savanna Habitat Restoration On Bat Activity In Eastern Nebraska, Aidan Hatfield, Jeremy White
Theses/Capstones/Creative Projects
Oak savanna habitat has been drastically reduced throughout the Midwest. Temperate bats generally are edge adapted and may better utilize a restored oak savanna habitat than the now common deciduous forests that replaced them. Therefore, we analyzed the activity of 7 bats native to eastern Nebraska and in the process, compared the agreement of two different programs that claim to automatically identify bat species. In order to investigate this, we placed three audio detectors within both habitats for 1 week and allowed them to record from sunset to sunrise. The data obtained was analyzed and compared between two programs, Kaleidoscope …
Lower Body Gait Variability As A Distinguishing Feature In Humans, Tyler M. Wiles, Seung Kyeom Kim, Nick Stergiou, Aaron D. Likens
Lower Body Gait Variability As A Distinguishing Feature In Humans, Tyler M. Wiles, Seung Kyeom Kim, Nick Stergiou, Aaron D. Likens
UNO Student Research and Creative Activity Fair
Most humans have a fingerprint that is unique and persists throughout life. The same may be true for gait. Each person is unique physiologically and biomechanically, and has experienced a unique progression of life including injuries, habits, hobbies, or lifestyles that all contribute to navigating the world. Those individualized experiences, whether intended or not, are potentially on display in gait. We hypothesized that there are gait characteristics intrinsic and unique to everyone, so that everyone has a unique “gaitprint”, similar to humans possessing unique fingerprints. To test our hypothesis, we recruited thirty healthy young adults between the ages 19-35 as …

Functional Outcomes Of Noninvasive Sensory Feedback In Upper Limb Prostheses: A Meta-Analysis, Libby Caldwell
UNO Student Research and Creative Activity Fair
Noninvasive sensory feedback applies vibration or pressure to the residual limb and is thought to improve the functionality of upper limb prostheses. However, the efficacy of this approach has not been sufficiently investigated, particularly regarding actual amputee efficacy. The purpose of this study was to evaluate the functional benefits of noninvasive sensory feedback in upper limb prostheses through a meta-analysis. Electronic databases (MEDLINE, Web of Science, and PubMed) were searched up to October 2022 using the following search terms: (prosthesis OR prosthetic) AND (hand OR arm OR forearm OR transradial OR “upper limb” OR “upper extremity) AND (tactile OR haptic …

Walking with a Load on Wheels: Potential Effects of Bidirectional Springs on Walking Economy
Have you ever noticed how your arms alternatively flex and extend when pushing a heavy shopping cart? Accelerating and decelerating heavy masses, such as a shopping cart, can require much effort. During walking, we alternatively accelerate and decelerate our Center of Mass (COM) in every gait cycle, which can require even more effort if we accelerate and decelerate a load while walking. Theoretically, this effort can be reduced by timing the acceleration and deceleration of the load's mass opposite to the individual's COM. Previous studies have …

The Denton Immunobiology Laboratory focuses on enhancing human natural killer (NK) cell killing capabilities, particularly in the context of combating cancer. NK cells are immune cells that have the ability to kill diseased cells via two mechanisms: direct killing, and antibody-dependent cell-mediated cytotoxicity (ADCC). We recently published our novel approach to testing both methods of killing by using NK cells derived from the same human donor. Our testing approach allows …

An ongoing thrust of research focused on human gait pertains to identifying individuals based on gait patterns. However, no existing gait database supports modeling efforts to assess gait patterns unique to individuals. Hence, we introduce the Nonlinear Analysis Core (NONAN) GaitPrint database containing whole body kinematics and foot placement during self-paced overground walking on a 200-meter looping indoor track. Noraxon Ultium MotionTM inertial measurement unit (IMU) sensors sampled the motion of 35 healthy young adults (19–35 years old; 18 men and 17 women; mean ± 1 s.d. age: 24.6 ± 2.7 years; height: 1.73 ± 0.78 m; body mass: …

Assays to quantify natural killer (NK) cell killing efficacy have traditionally focused on assessing either direct killing or antibody dependent cell-mediated cytotoxicity (ADCC) independently. Due to the probability that immunotherapeutic interventions affect NK cell-mediated direct killing and NK cell-mediated ADCC differently, we developed an assay with the capacity to measure NK cell-mediated direct killing and ADCC simultaneously with cells from the same human donor. Specifically, this design allows for a single NK cell population to be split into several experimental conditions (e.g., direct killing, ADCC), thus controlling for potential confounders associated with human-to-human variation when assessing immunotherapy impacts. Our Natural …

Quantifying Non-Gaussian Intermittent Fluctuations In Physiology: Multiscale Probability Density Function Analysis Using The Savitzky-Golay Detrending, Madhur Mangalam, Damian G. Kelty-Stephen, Eiichi Watanabe, Ken Kiyono
Journal Articles
When measuring physiological data, the central limit theorem typically implies a consistent variance, resulting in data that closely follow a Gaussian distribution. However, physiological measurements often deviate from this expectation, increasing variance due to nonlinear correlations across various scales. The challenge lies in testing these tails, which comprise only rare and extreme values. We introduce multiscale probability density function (PDF) analysis, a method that estimates this non-Gaussianity parameter for physiological fluctuations in each of multiple timescales. We gain valuable insights into the observed distributions with heavier tails and nonlinear correlations by exploring the relationship between non-Gaussianity and logarithmic scale. To …

Multifractality In Stride-To-Stride Variations Reveals That Walking Involves More Movement Tuning And Adjusting Than Running, Taylor J. Wilson, Madhur Mangalam, Nicholas Stergiou, Aaron Likens
Journal Articles
Introduction: The seemingly periodic human gait exhibits stride-to-stride variations as it adapts to the changing task constraints. The optimal movement variability hypothesis (OMVH) states that healthy stride-to-stride variations exhibit “fractality”—a specific temporal structure in consecutive strides that are ordered, stable but also variable, and adaptable. Previous research has primarily focused on a single fractality measure, “monofractality.” However, this measure can vary across time; strideto-stride variations can show “multifractality.” Greater multifractality in stride-tostride variations would highlight the ability to tune and adjust movements more.
Methods: We investigated monofractality and multifractality in a cohort of eight healthy adults during self-paced walking and …

Inducing antiretroviral therapy (ART)-free virological control is a critical step toward a human immunodeficiency virus type 1 (HIV-1) cure. In this phase 2a, placebo-controlled, double-blinded trial, 43 people (85% males) with HIV-1 on ART were randomized to (1) placebo/placebo, (2) lefitolimod (TLR9 agonist)/placebo, (3) placebo/broadly neutralizing anti-HIV-1 antibodies (bNAbs) or (4) lefitolimod/bNAb. ART interruption (ATI) started at week 3. Lefitolimod was administered once weekly for the first 8 weeks, and bNAbs were administered twice, 1 d before and 3 weeks after ATI. The primary endpoint was time to loss of virologic control after ATI. The median delay in time to …

Temporal Organization Of Stride-To-Stride Variations Contradicts Predictive Models For Sensorimotor Control Of Footfalls During Walking, Madhur Mangalam, Damian G. Kelty-Stephen, Joel H. Sommerfeld, Nicholas Stergiou, Aaron Likens
Journal Articles
Walking exhibits stride-to-stride variations. Given ongoing perturbations, these variations critically support continuous adaptations between the goal-directed organism and its surroundings. Here, we report that stride-to-stride variations during self-paced overground walking show cascade-like intermittency—stride intervals become uneven because stride intervals of different sizes interact and do not simply balance each other. Moreover, even when synchronizing footfalls with visual cues with variable timing of presentation, asynchrony in the timings of the cue and footfall shows cascade-like intermittency. This evidence conflicts with theories about the sensorimotor control of walking, according to which internal predictive models correct asynchrony in the timings of the cue …

Ergodic Characterization Of Nonergodic Anomalous Diffusion Processes, Madhur Mangalam, Ralf Metzler, Damian G. Kelty-Stephen
Ergodic Characterization Of Nonergodic Anomalous Diffusion Processes, Madhur Mangalam, Ralf Metzler, Damian G. Kelty-Stephen
Journal Articles
Anomalous diffusion in various complex systems abounds in nature and spans multiple space and time scales. Canonical characterization techniques that rely upon mean squared displacement break down for nonergodic processes, making it challenging to characterize anomalous diffusion from an individual time-series measurement. Nonergodicity reigns when the time-averaged mean square displacement differs from the ensemble-averaged mean squared displacement even in the limit of long measurement series. In these cases, the typical theoretical results for ensemble averages cannot be used to understand and interpret data acquired from time averages. The difficulty then lies in obtaining statistical descriptors of the measured diffusion process …

The Study Of A Generalized Fitness Education Program's Effect On Personality Traits, Garrett Schliep
Theses/Capstones/Creative Projects
This longitudinal study was to measure the influence of a generalized fitness education program on the percentile of individuals’ personality traits in college aged individuals. The personality traits are those determined in the Five Factor Model of Personality. The Five Factor Model of Personality is a beneficial tool used in exercise psychology that refers to a broad domain of personality traits often referred to as the “Big Five”. The findings reject the hypothesis that a fitness education program would shift an individual’s personality a statistically significant amount.

Correlation Between Stress Coping Styles And Genetic Variation In The Adenosine Pathway Of Zebrafish, Sydney Klucas
Theses/Capstones/Creative Projects
Anxiety is a common mental disorder and is caused in part by dysregulation of neurotransmitter systems. Specifically, the adenosine pathway has been correlated with anxiety disorders, but it is not yet known if genetic differences in this pathway are responsible for anxiety-related behavior. In this study, I used bioinformatic analyses (EdgeR and WGCNA) to investigate an RNA-sequencing dataset to assess differences in differential gene expression and gene co-expression networks within the adenosine pathway of zebrafish with different stress coping styles. These analyses included three brain regions: basolateral amygdala, hippocampus, and habenula. The differential gene expression analysis demonstrated that the adenosine …

Endocrine disrupting chemicals (EDCs) are substances in the environment, food sources, personal care products, and manufactured products that interfere with the normal function of the body’s endocrine system. Most humans are exposed to some amount of these chemicals from many different sources, such as the air we breathe, food we eat, and the water we drink. EDCs can also permeate through the skin. The endocrine system is important because it works with other systems in the body to ensure healthy development and function throughout life. EDCs interfere with the way our body’s hormones work. Some EDCs can mimic natural hormones …

Gaze During Turning In Older Adults, Kalina Mavrov
Theses/Capstones/Creative Projects
To navigate complex environments, our gaze needs to attenuate to locomotor tasks, such as walking and turning. Shifting gaze (i.e., rotation of the eyes and head), is important when moving through different environments. The aim of this study was to compare gaze anticipation during clinical tests and complex real-world locomotion. I hypothesized that older adults would shift their gaze in a new heading direction in anticipation of turns. I further predicted increased gaze anticipation in tasks that have a high demand for spatial orientation. Participants were asked to complete clinical tasks consisting of a 2-minute walk, figure-8, and 360-turning in …

Accelerometry-Based Analysis Of Postural Sway In Parkinson's Disease Patients With Levodopa-Induced Dyskinesia, Chandler Brock
UNO Student Research and Creative Activity Fair
Parkinson’s disease (PD) is a progressive neurodegenerative disorder, with patient numbers projected to double to 12 million in the next 20 years. Levodopa-induced dyskinesia (LID) is a major problem associated with the long-term use of levodopa for symptomatic treatment of PD. These involuntary movements can become disabling and may interfere with quality of life. Our prior research showed that PD w/ LID were less stable while standing (i.e., increased postural sway) and had a higher incidence of falls. The aim of this study is to determine if postural sway properties are altered by LID via decomposing the sway signal. We …
