Determining The Distribution Of Elemental Compounds And Oxidative Potential Across Fine Particulate Matter (Pm2.5) Filters, Allie Michelle Sidwell
Determining The Distribution Of Elemental Compounds And Oxidative Potential Across Fine Particulate Matter (Pm2.5) Filters, Allie Michelle Sidwell
Honors Theses
Fine particulate matter (PM2.5) is a complex mixture of particles and sorbed chemicals that poses serious, adverse effects on human health such as increasing cardiovascular and respiratory morbidity and mortality. There is ongoing research into the impacts of PM2.5 of differing chemical compositions, sampling location, and the mechanisms for the observed health effects. To conduct these analytical and toxicology studies of PM2.5, researchers often split filters into sections. This process allows multiple, often destructive, assays to be performed. Our previous research showed chemical composition differences across PM2.5 filters. The goal of our study was …
The Potential For Dickeya Dianthicola To Be Vectored By Two Common Insect Pests Of Potatoes, Jonas K. Insinga
The Potential For Dickeya Dianthicola To Be Vectored By Two Common Insect Pests Of Potatoes, Jonas K. Insinga
Electronic Theses and Dissertations
Dickeya dianthicola (Samson) causing blackleg and soft rot was first detected in potatoes grown in Maine in 2014. Previous work has suggested that insects, particularly aphids, may be able to vector bacteria in this genus between plants, but no conclusive work has been done to confirm this theory. In order to determine whether insect-mediated transmission is likely to occur in potato fields, two model potato pests common in Maine were used: the Colorado potato beetle (Leptinotarsa decimlineata Say) and the green peach aphids (Myzus persicae Sulzer). Olfactometry and recruitment experiments evaluated if either insect discriminates between infected and …
The Effect Of Ammonia On The Germination And Outgrowth Of Bacillius Globigii, Joseph B. Kunicki
The Effect Of Ammonia On The Germination And Outgrowth Of Bacillius Globigii, Joseph B. Kunicki
Theses and Dissertations
This research investigated the germination and outgrowth of Bacillus globigii in the presence of ammonia in laboratory scale experiments. Germination was measured by monitoring the release of dipicolinic acid, an organic compound present in bacterial spores, while outgrowth was measured using phase-bright microscopy and semi-automated counting procedures. The ammonia-N concentrations investigated generally did not cause statistically significant differences in the initial 1-hr germination rates or the average 3-hr outgrowth rates of Bacillus globigii spores in batch style experiments. The average 1-hr germination rates observed in the absence of ammonia-N was 0.0258 hr-1 for the water and buffer controls and …
Interleukin-6 And Exercise; Early Evidence Of A Novel Myokine, Brendan Hogg Mr.
Interleukin-6 And Exercise; Early Evidence Of A Novel Myokine, Brendan Hogg Mr.
Graduate Student Theses, Dissertations, & Professional Papers
Interleukin-6 (IL-6) was first identified as a pleiotropic cytokine, with a host of body-wide functions. Cytokine functions are characterized by chronically elevated levels within various inflammatory states. In this regard, IL-6 is largely associated with the acute phase response to many stimuli and performs specific actions when produced from certain cell types. Accrued evidence indicates IL-6 release from skeletal muscle often includes myokine functions. Novel myokine functions are adaptive in nature, and as compared to inflammatory/cytokine roles, exhibit a transient time course. Following exercise plasma IL-6 peaks and returns to resting levels within 1-2 hours. In contrast, IL-6 is observed …
Structure Of The Picornavirus Replication Platform: A Potential Drug Target For Inhibiting Virus Replication, Meghan Suzanne Warden
Structure Of The Picornavirus Replication Platform: A Potential Drug Target For Inhibiting Virus Replication, Meghan Suzanne Warden
Chemistry & Biochemistry Theses & Dissertations
Picornaviruses are small, positive-stranded RNA viruses, divided into twelve different genera. Members of the Picornaviridae family cause a wide range of human and animal diseases including the common cold, poliomyelitis, foot and mouth disease, and dilated cardiomyopathy. The picornavirus genome is replicated via a highly conserved mechanism involving a presumed cloverleaf structure located at the 5’ noncoding region of the virus genome. The 5’ cloverleaf consists of three stem loops (B, C, and D) and one stem (A), which interact with a variety of virus and host cell proteins during replication. In this dissertation, human rhinovirus serotype 14 (HRV-14) SLB …
Comparing The Quantitation Of Opiates From Possible Drug Overdose Cases Using Results Of Blood Analysis And Liver Analysis, Lee Ann Garozzo
Comparing The Quantitation Of Opiates From Possible Drug Overdose Cases Using Results Of Blood Analysis And Liver Analysis, Lee Ann Garozzo
Forensic Science Theses
Currently the quantitation of opiates at the Erie County Medical Examiner’s Office Toxicology Laboratory is conducted through whole blood analysis. The objective of this thesis project was to determine if the analysis of opiates could be conducted through liver analysis, and if the analysis of opiates would provide a more accurate quantitation compared to the blood analysis. The quantitation of opiates was conducted from the livers of sixty-four possible overdose cases that were brought into the Erie County Medical Examiner’s Office between 2013 and 2015. Results showed that the opiate drugs could successfully be quantitated using the liver analysis. Generally …
Efficacy Of Cleaning Method For Removal Of Exogenous Welding Fume Contamination From Nail Tissue Prior To Use As A Biomarker For Welding Fume Manganese Exposure, Jeffrey Corral Bainter
Efficacy Of Cleaning Method For Removal Of Exogenous Welding Fume Contamination From Nail Tissue Prior To Use As A Biomarker For Welding Fume Manganese Exposure, Jeffrey Corral Bainter
Open Access Theses
Nail tissue has been proposed as a biomarker for body burden of occupational exposure to manganese from welding fumes. Though recent studies have shown correlation between manganese exposure and both nail tissue concentration as well as concentrations in dopaminergic regions of the brain, concerns of the validity of nail tissue as a biomarker have arisen due to the potential for exogenous contamination of Mn to undermine the quantization of endogenous Mn in nail. Previous studies have used a cleaning method of 1% Triton X-100 surfactant plus sonication in order to attempt to remove exogenous welding fume contamination. Determination of the …
Production Of A Monoclonal Antibody Against Benzo[Α]Pyrene Diol Epoxide Dna Adducts, Brian Peden Austin
Production Of A Monoclonal Antibody Against Benzo[Α]Pyrene Diol Epoxide Dna Adducts, Brian Peden Austin
Chemistry & Biochemistry Theses & Dissertations
Benzo[α]pyrene is a ubiquitous pollutant produced from the incomplete combustion of organic material such as fossil fuels. It is found in the workplace, urban air, drinking water, and the food supply. Recently, it has been proposed that benzo[α]pyrene may be the causative agent in the formation of lung adenocarcinomas among some Taiwanese women exposed to cooking oil fumes without adequate ventilation. In this study, calf thymus DNA was modified in vitro with benzo[α]pyrene-diol epoxide (BPDE) to a level consistent with that found in biological samples. This DNA of low modification was used as an immunogen in the production of a …
