Antibiotic Resistant Gene Concentrations In Bacteria In Groundwater From Agricultural Waste, Koji Barnaby Jan 2021

Antibiotic Resistant Gene Concentrations In Bacteria In Groundwater From Agricultural Waste, Koji Barnaby

Mahurin Honors College Capstone Experience/Thesis Projects

The overuse of antibiotics has led to an increase in antibiotic resistant bacteria since some antibiotics are sent into the wastewater system by waste produced by both humans and agriculture, making exposure to these bacteria more likely. The evolution of these bacteria in groundwater is of particular concern, as groundwater is used as a source of drinking water, and infections by these bacteria would be more difficult to treat. There are no policies in place to monitor or regulate antibiotic resistance bacteria in groundwater, leaving the threat to public health unknown. The study area of Crumps Cave in Smiths Grove, …

Effect Of Acute Sleep Fragmentation Upon Inflammatory Response Of Brown And White Adipose Tissue In Male Mice, Zach Wriedt Jan 2021

Effect Of Acute Sleep Fragmentation Upon Inflammatory Response Of Brown And White Adipose Tissue In Male Mice, Zach Wriedt

Mahurin Honors College Capstone Experience/Thesis Projects

Sleep is an important process required for vertebrates, including humans, to function. When sleep is disrupted, it leads to deleterious effects such as inflammatory responses throughout the body. Past studies have shown that acute (24 h) sleep fragmentation (SF) leads to an inflammatory response in white adipose tissue. However, whether brown adipose tissue responds in a similar fashion is unknown. Male adult (>8 weeks of age) C57BL/6j mice were subjected to SF for 24 h using a cage outfitted with a bar that moves horizontally across the cage every 2 min to periodically awaken mice (N =10). Controls were …

The Effect Of Age On Neurological Inflammation To Acute Sleep Fragmentation In Mice, Molly Taylor Jan 2021

The Effect Of Age On Neurological Inflammation To Acute Sleep Fragmentation In Mice, Molly Taylor

Mahurin Honors College Capstone Experience/Thesis Projects

Obstructive sleep apnea is identified by recurring events of airway collapse during sleep, intermittent hypoxia, and perturbations in sleep continuity, known as sleep fragmentation. There is evidence to suggest that elderly patients are more at risk of developing obstructive sleep apnea. The purpose of this study was to assess whether age affects neurological inflammatory responses to acute sleep fragmentation. This assessment was made by subjecting young (4-5 months old) and old (10-11 months old) male C57BL/6j mice to automated sleep fragmentation, as well as having mice in both age categories as a control with no sleep fragmentation, for twenty-four hours. …

A Review And Comparison Of U.S. State Wildlife Action Plans For Stonefly (Insecta, Plecoptera) Species Of Greatest Conservation Need, Kathryn Greene Jan 2021

A Review And Comparison Of U.S. State Wildlife Action Plans For Stonefly (Insecta, Plecoptera) Species Of Greatest Conservation Need, Kathryn Greene

Mahurin Honors College Capstone Experience/Thesis Projects

State Wildlife Action Plans (SWAPs) were created in order to identify Species of Greatest Conservation Need (SGCN) and develop plans to prevent their populations from further decline and the possibility of being listed as threatened or endangered. Which SGCNs are included are decided based on characteristics that determine their vulnerability. As of early 2021, approximately 720stoneflies (Insecta, Plecoptera) species are found in the U.S., but only 143 are listed as SGCN. Only 29 states have stoneflies included on their SGCN lists, but 37 states use EPT (Ephemeroptera + Plecoptera + Trichoptera) metrics when assessing water quality issues in running water …

Alfred Russel Wallace Notes 15. Wallace's Many "Hats": What Should We Call Him?, Charles H. Smith Jan 2021

Alfred Russel Wallace Notes 15. Wallace's Many "Hats": What Should We Call Him?, Charles H. Smith

Faculty/Staff Personal Papers

Alfred Russel Wallace (1823−1913) has been referred to by name through the aid of a variety of labels – some thirty or more, in fact – that link him to his emphases of attention. How many of these labels are/were justifiable? The assessment here is that he is probably best remembered as a ‘naturalist,’ ‘geographer,’ ‘evolutionist,’ and ‘social critic.’

Alfred Russel Wallace Notes 8: Wallace's Earliest Exposures To The Writings Of Alexander Von Humboldt, Charles H. Smith Jan 2021

Alfred Russel Wallace Notes 8: Wallace's Earliest Exposures To The Writings Of Alexander Von Humboldt, Charles H. Smith

Faculty/Staff Personal Papers

For many years it has been known that the German geographer and naturalist Alexander von Humboldt (1769-1859) exercised a considerable influence on Alfred Russel Wallace’s (1823-1913) decision to become a travelling naturalist. Almost no attention, however, has been given to the real possibility that von Humboldt exerted an even greater influence on Wallace’s general worldview. In this note, Wallace’s probable earliest contacts with von Humboldt’s writings are described.

No Changes In Appetite-Related Hormones Following Swimming And Cycling Exercise Interventions In Adults With Obesity, Brandon G. Fico, Mohammed Alkatan, Hirofumi Tanaka Nov 2020

No Changes In Appetite-Related Hormones Following Swimming And Cycling Exercise Interventions In Adults With Obesity, Brandon G. Fico, Mohammed Alkatan, Hirofumi Tanaka

International Journal of Exercise Science

International Journal of Exercise Science 13(2): 1819-1825, 2020. Swimming is a favorable and ideal modality of exercise for individuals with obesity and arthritis as it encompasses a minimal weight-bearing stress and a reduced heat load. However, the available evidence indicates that regular swimming may not be effective in reducing body weight and body fatness. A current hypothesis is that exercise in cold water stimulates appetite. We determined the effect of swimming training on appetite-related hormones. Thirty-nine adults with obesity and osteoarthritis were randomly assigned to 12 weeks of supervised swimming or cycling training. In the initial few weeks, participants exercised …

Alfred Russel Wallace Notes 12: How Good Was Wallace's Memory?, Charles H. Smith Nov 2020

Alfred Russel Wallace Notes 12: How Good Was Wallace's Memory?, Charles H. Smith

Faculty/Staff Personal Papers

Alfred Russel Wallace (1823−1913) continues to be criticized for inconsistencies in his recollections of the earlier events in his life. This criticism, while not entirely unjust, has nevertheless been overplayed. Critics have not attended to the general understanding that self-biography is under the influence of two aspects of memory: that pertaining to remembrance of the qualities of past situations, and a secondary ability to assign absolutes of name or date to such memories. All evidence suggests that Wallace’s memory in the first sense was excellent throughout his life, but that he was prone to lapses of the second type.

Alfred Russel Wallace Notes 13: Wallace On Prayer, Charles H. Smith

Faculty/Staff Personal Papers

Alfred Russel Wallace (1823−1913) is known to most for his natural history explorations and theoretical biology, but he also developed thoughts on a number of subjects relatable to a wider appreciation of evolutionary cosmology. His adoption of spiritualism, for one, was attuned to this mission, and in turn his otherwise difficult-to-interpret two-sided position on prayer.

International Journal of Exercise Science

International Journal of Exercise Science 13(4): 1718-1728, 2020. The purpose of this study was to compare the Skulpt Chisel™ to seven-site skinfold (SKF) and hydrostatic weighing (HW) body fat percentage (%BF) estimates. Twenty-six participants (aged 24 ± 4 years; BMI 23.1 ± 3.5 kg∙m-2) were assessed. Significant differences in %BF estimates were found for all methodological pairings; p < 0.05. The SKF method underestimated %BF compared to HW (-2.52 ± 3.42 %BF). The Skulpt Chisel™ overestimated %BF compared to both HW (3.38 ± 6.10 %BF) and SKF (5.90 ± 5.26 %BF). Limits of agreement comparing HW to Skulpt Chisel™ indicated a difference between 95% confidence interval bounds (Upper bound: 5.84 %BF, Lower bound 0.92 %BF) and for HW to SKF (Upper bound: -1.14 %BF, Lower bound: -3.91 %BF). Regression analysis showed no significant bias for any methodological pairing; (p > 0.05). In conclusion, the Skulpt Chisel™ method should be used with caution when evaluating %BF of adults with similar demographics reported in this study.

International Journal of Exercise Science

International Journal of Exercise Science 13(3): 1638-1649, 2020. The aims of this study were: (i) to analyze the relationship between the performance of different measures of muscular strength, and (ii) to identify which measurements present a greater relationship with an overall strength score. Sixty older women (aged 69 ± 6 years) were submitted to muscular strength measurements from isotonic, isokinetic, and isometric tests. An overall-strength score was generated with z-scores of the values obtained in all tests. Interquartile intervals were created for each measure and the overall-strength score. Pearson’s r (0.463-0.951, p < 0.05) and Cronbach’s α (0.500-0.966) suggested that subjects had relatively similar strength performance compared to their peers in the different tests. Greater associations were observed between tests for similar tasks. In addition, strong-magnitude associations were revealed between all the tests and the overall-strength score (r = 0.710-0.806; α = 0.760-0.846). Factor …
