Investigating The Genetic Structure Of Northern Long-Eared Bats In Nebraska, Jonathan Korbitz
Investigating The Genetic Structure Of Northern Long-Eared Bats In Nebraska, Jonathan Korbitz
UNO Student Research and Creative Activity Fair
Abstract:
The northern long-eared bat (Myotis septentrionalis) is one of many species of hibernating bats in North America affected by a recently discovered fungal disease called white-nose syndrome (WNS). Northern long-eared bats seem to be extremely susceptible to the disease with mass fatalities occurring among populations in eastern North America. Researchers in the eastern distribution of this species have performed mtDNA analysis to identify the population structure of the species; however, genetic analysis has yet to be done in western parts of its distribution. The goal of this study is to create a better understanding of the genetic …

Neutrophils in the Geniculate Ganglion Following Chorda Tympani Transection in Adult Rats
The chorda tympani nerve (CT) innervates taste buds on the tongue. The CT’s cell bodies are in the geniculate ganglion (GG). Previous work in our lab found that severing the CT (CTX) results in a reduction of taste bud numbers, and substantial immune responses at the tongue and in the brain. However, there is limited information on how the immune system responds at the GG following CTX. Neutrophils are critical members of the first wave of immune response to nerve injury, attacking foreign pathogens and clearing debris. The …

Exercise training is recommended for maintaining health and reducing the risks of developing metabolic and cardiovascular pathologies. Combined resistance and aerobic exercise (CRAE) training has been utilized to decrease metabolic risk factors in obese adults. PURPOSE: To determine the effects of CRAE on obese adolescent females with hyperinsulinemia. METHODS: Forty obese adolescent females aged 14.7 ± 1 years (BMI …
A Novel Task To Decrease Step Width Variability In Older Adults, Andreas Skiadopoulos, Katherine Allen, Nikolaos Stergiou
A Novel Task To Decrease Step Width Variability In Older Adults, Andreas Skiadopoulos, Katherine Allen, Nikolaos Stergiou
UNO Student Research and Creative Activity Fair
Walking is the most common fall-related activity among older adults. Also, older adults experience greater step width variability when walking. Importantly, increased step width variability during walking has been found to be a strong predictor of fall risk and incidence. Therefore, an intervention for reducing increased step width variability may consequently reduce fall risk for older adults. In the present study, we proposed that lateral stepping training program improve walking in older adults by reducing the increased step width variability to normal values. Therefore, the purpose of the present study is to determine the effect of a six-week lateral stepping …
The Effects Of Vibrations On The Light Touch Perception Threshold Of Transtibial Amputees, Aaron Robinson
The Effects Of Vibrations On The Light Touch Perception Threshold Of Transtibial Amputees, Aaron Robinson
UNO Student Research and Creative Activity Fair
Sensations from the residual limb and the prosthetic socket interface may be important for mobility/balance following an amputation. One potential way to improve sensation in the residual limb-socket interface is the use of sub-threshold vibrations. We hypothesized that the application of a subthreshold pink noise vibration will improve an amputee’s ability to perceive a light touch stimulus in the residual limb surrounding the area of the amputation. 20 unilateral transtibial amputees (ages 59.7±15 yrs) and seventeen healthy control subjects (ages 54.1±16 yrs) participated. For transtibial amputees light touch sensation threshold (LTST), baseline was tested first and then across 3 conditions …
Circadian Rhythms And Stride-To-Stride Fluctuations: Is There A Connection ?, Joao R. Vaz
Circadian Rhythms And Stride-To-Stride Fluctuations: Is There A Connection ?, Joao R. Vaz
UNO Student Research and Creative Activity Fair
Several physiological systems exhibit rhythmic changes over the course of 24h. A disruption in the CR is thought to represent a risk to the human’s health (e.g., cardiac risk, diabetes). Aging and neurological diseases are known to be characterized by an increased likelihood of circadian disruption. Recently, balance and gait have been shown to exhibit diurnal variations, suggesting a possible influence of CR. Gait is also characterized by a certain level of stride-to-stride fluctuations. In addition, a breakdown in the temporal structure of these fluctuations has recently been associated with aging and neurological diseases. Therefore, it is likely that a …
Comparison Of Amygdalar Neuronal Networks That Regulate Fear Behaviors Among Vertebrates, Sushmita Adhikari
Comparison Of Amygdalar Neuronal Networks That Regulate Fear Behaviors Among Vertebrates, Sushmita Adhikari
UNO Student Research and Creative Activity Fair
Introduction and Methods: Fear is a basic, conserved emotion that is essential for survival, yet little is known about how fear responses evolved. This research combined gene expression and behavioral analyses to study the evolution of the neuronal network that regulates fear behaviors. Using in situ hybridization, we examined the expression patterns of three genes, protein kinase C δ (prkcd), gastrin-releasing peptide (grp), and glypican 3 (gpc3), that are implicated in fear behaviors in Danio rerio (zebrafish), Xenopus tropicalis, and Gallus gallus domesticus. Additionally, anxiety behaviors were examined in young zebrafish that lacked genes for grp, grp receptor (grpr), and …

The Role Of The Chorda Tympani Nerve In The Structural Development Of Brainstem Neurons, Louis Martin
The Role Of The Chorda Tympani Nerve In The Structural Development Of Brainstem Neurons, Louis Martin
UNO Student Research and Creative Activity Fair
The brain changes substantially throughout development. In the taste system, brainstem neurons undergo dramatic structural alterations after birth. Most notably, these cells’ dendrites, branch-like projections that that receive sensory input, grow 3-4 times longer by adulthood. It is not clear whether incoming signals about taste are necessary for these structural changes to occur. We have consistently found that when the chorda tympani taste nerve (CT) is cut at an early age in rats, it does not regenerate. With this manipulation, we can permanently limit the amount of taste information that reaches the brain. To determine the role of taste input …
Differences In Habenula Kisspeptin Expression And Its Effects On Stress Coping Styles In Zebrafish, Danio Rerio, Andrew Wahl
Differences In Habenula Kisspeptin Expression And Its Effects On Stress Coping Styles In Zebrafish, Danio Rerio, Andrew Wahl
UNO Student Research and Creative Activity Fair
Two particular styles of stress coping behaviors have been identified as evolutionarily conserved across vertebrate species and are referred to as proactive and reactive. Reactive and proactive stress coping styles have distinct 5-HT expression profiles with greater expression of 5-HT found in proactive individuals. It was previously shown that kiss1 expression in the ventral habenula (vHb) presynaptically activates kiss-r1 which can alter glutamatergic levels in co-localizing cells in the vHb that terminate in the median raphe (MR). This can directly or indirectly increase 5-HT expression in the MR via glutamate. It is unknown whether kisspeptin expression in the vHb can …
