A Potential Klebsiella Bacteriocin With Efficacy Toward The Enterbacteriaceae Family, Kasey Barber
A Potential Klebsiella Bacteriocin With Efficacy Toward The Enterbacteriaceae Family, Kasey Barber
Undergraduate Honors Theses
Drug resistance is unfortunately becoming a prevalent issue in the course of patient treatment, ranging from chemotherapy resistance to antimicrobial resistance. The Centers for Disease Control and Prevention (CDC) estimated in 2016 that at least 23,000 people die every year in the United States from an infection with an antibiotic-resistant organism (Munita, et al, 2016). Carl Friedlander was the first scientist to describe Klebsiella pneumoniae in 1882 as an encapsulated bacillus after isolating the bacterium from the lungs of patients who had died from pneumonia (Ashurst and Dawson, 2022). Klebsiella pneumoniae is the type species for the Klebsiella genus and …
Nicotinamide Riboside And Beta-Hydroxybutyrate Activate Parallel Pathways For C. Elegans Lifespan Extension, Mckenzie Peters
Nicotinamide Riboside And Beta-Hydroxybutyrate Activate Parallel Pathways For C. Elegans Lifespan Extension, Mckenzie Peters
Undergraduate Honors Theses
Supplementation with nicotinamide riboside (NR), a form of vitamin B3 and a precursor of nicotinamide adenine dinucleotide (NAD+) extends lifespan in the nematode C. elegans and delays aging-related pathologies in mammals. During aging, levels of NAD+ decline causing metabolic dysfunction and oxidative damage. Studies in C. elegans found that when NR was administered during larval development it induced the mitochondrial unfolded protein response (UPRmt), which is frequently associated with lifespan extension. Both calorie restriction (CR) and ketogenic diets (KD) have been shown to extend lifespan, in part through increasing NAD+ and through increasing levels …
Effects Of Nicotinamide Riboside And Beta-Hydroxybutyrate On C. Elegans Lifespan, Jeffery Peters
Effects Of Nicotinamide Riboside And Beta-Hydroxybutyrate On C. Elegans Lifespan, Jeffery Peters
Undergraduate Honors Theses
The nicotinamide riboside (NR) form of vitamin B3and the ketone body ß-hydroxybutyrate (BHB) are two of the most promising natural compounds yet identified for the treatment of aging and aging-related diseases. Forms of vitamin B3are precursors for the synthesis of the coenzymes nicotinamide adenine dinucleotide (NAD(H)) and nicotinamide adenine dinucleotide phosphate (NADP(H)). In aged cells levels of NAD+decline, decreasing metabolism and decreasing activity of protective sirtuin protein deacetylases. In aged cells NR, but not more common forms of vitamin B3, boost NAD+levels. BHB is naturally produced by the body when individuals fast …
Ctrp3 And Alcoholic Liver Disease In Female Mice, Callie Root
Ctrp3 And Alcoholic Liver Disease In Female Mice, Callie Root
Undergraduate Honors Theses
C1q TNF Related Protein 3 (CTRP3), is a cytokine that is primarily secreted from adipose tissue, which classifies it as an adipokine. Our previous research has shown that CTRP3 prevents alcoholic fatty liver disease (ALD) in male mice. However, even when accounting for confounding factors such as absolute and relative alcohol intake, females are more sensitive to the effects of consumption compared to male mice. Therefore, the goal of this project was to determine whether CTRP3 prevented ALD in female mice. Methods: Female wild type (WT) and female CTRP3 transgenic over expressing (Tg) mice were fed an ethanol containing liquid …
Isolation, Analysis, And Partial Characterization Of An Inhibitor Of Neisseria Gonorrhoeae, Natania Paul
Isolation, Analysis, And Partial Characterization Of An Inhibitor Of Neisseria Gonorrhoeae, Natania Paul
Undergraduate Honors Theses
There is an emerging threat of Neisseria gonorrhoeae strains that are resistant to all antibiotics. Because of this, the purpose of this research is to isolate, analyze, and partially characterize a new inhibitor(s) of N. gonorrhoeae. Since there is an unknown molecule secreted by Candida albicans that inhibits N. gonorrhoeae, this molecule can be partially characterized using 1H NMR Spectroscopy to assist in the development of a new antibiotic compound. It was hypothesized that quorum-sensing molecules, trans, trans- farnesol, tyrosol, phenylethyl alcohol, and tryptophol, could be possible candidates for the inhibitor. Because of this, 1H …
Chat Expression In Chlamydia Muridarum-Infected Female Murine Genital Tract, Hallie Sartain
Chat Expression In Chlamydia Muridarum-Infected Female Murine Genital Tract, Hallie Sartain
Undergraduate Honors Theses
Chlamydia trachomatis is the most prevalent agent of bacterial sexually transmitted infections in the world. However, a profuse number of cases are unreported, as the infection is often asymptomatic. Sequelae such as pelvic inflammatory disease, an increased risk of cervical cancer, premature birth, and perinatal infections in pregnant women can occur. Inflammation occurs in the body in response to infection or injury. Although inflammation can lead to some unwanted secondary effects, such as pain, it serves to return the body to homeostasis by restoring injured tissues and eliminating pathogens. One recently identified connection between the central nervous system and the …
The Effects Of Chronic Alcohol Consumption On Ovarian Function/ Morphology, Destiny Roberts
The Effects Of Chronic Alcohol Consumption On Ovarian Function/ Morphology, Destiny Roberts
Undergraduate Honors Theses
Chronic alcohol (ethanol) consumption has been known to affect the major organs of the body and particularly the liver. However, the effects of chronic ethanol consumption on the female reproductive system remain relatively unstudied. A convenient way to study these effects is by analyzing laboratory mice that have been fed an ethanol diet for an extended period of time and comparing them to control mice. In this study, female mice were separated into control and ethanol fed groups. The mice were placed on their specified diets and observed over the course of six weeks. The mice were fed and weighed …
Synthesis And In-Vitro Cell Viability/Cytotoxicity Studies Of Novel Pyrrolobenzodiazepine Derivatives, John M. Jarrett
Synthesis And In-Vitro Cell Viability/Cytotoxicity Studies Of Novel Pyrrolobenzodiazepine Derivatives, John M. Jarrett
Undergraduate Honors Theses
Pyrrolobenzodiazepines (PBDs) are a group of naturally occurring compounds that were discovered in the cultures of Streptomyces in the 1960s. Some natural PBDs discovered in these cultures, such as anthramycin and sibiromycin, were shown to possess a broad spectrum of anti-tumor activity. Since cancer is still a leading cause of death globally, the development of novel anti-proliferative derivatives of PBDs is essential for human welfare worldwide. Further synthesis and structure-activity relationship (SAR) studies of the parent natural products and their tetracyclic analogs will lead to the discovery of drug candidates. In this work, thirteen PBD analogues were synthesized using no …
A Systematic Column Performance Comparison For The Confirmation Of Opioids Used In Pain Management By Lc-Ms, Derek Stallard
A Systematic Column Performance Comparison For The Confirmation Of Opioids Used In Pain Management By Lc-Ms, Derek Stallard
Undergraduate Honors Theses
In this study, three different chromatographic column chemistries (C18, Pentafluorophenyl (PFP), Hydrophilic Interaction Chromatography (HILIC)) were compared under optimal conditions to determine which stationary performed best in the separation and detection of a mixture of opioids using LC-MS. Furthermore, these stationary phases were examined in three different column technologies – traditional silica, porous shell, and porous polymer (PRP). The PRP column had the best peak shape for all 13 opioids and dominated for later-eluting compounds. In terms of column reproducibility, the Hamilton C18 column had the lowest %RSD values. The Kinetex HILIC produced the most theoretical plates and best resolution …
