Abstract:: Wastewater epidemiology is an emerging discipline that requires collaborative research involving analytical chemists, drug epidemiologists, and wastewater engineers. Wastewater epidemiology involves the sampling and quantitative analysis of raw wastewaters from communities for illicit drugs and their metabolites. Mass loads (mass per day) and per capita (mg per day per person)...

Abstract:: This research was undertaken to develop a sensitive, selective, and rapid analytical method to measure ethyl glucuronide (EtG) and ethyl sulfate (EtS) in urine as urinary biomarkers of alcohol exposure. Large-volume injection (LVI) coupled with liquid chromatography / electrospray tandem mass spectrometry was used to eliminate the need for either...

Creator:: Mandrell, David
Abstract:: The field of nanotechnology has been rapidly developing new materials. These materials have become incorporated into consumer products and the environment after only minimal assessment of their effects on human health or the environment. The toxicity of these new nanomaterials remains unknown due to the unpredictable nature of the core...

Abstract:: Peptide-phosphorodiamidate morpholino oligomers (PPMOs) are synthetic DNA mimics that bind and silence gene targets. Through designing PPMOs that silence essential or resistance genes in pathogens, these antisense oligomers could be utilized as novel antimicrobials. Towards this end, my thesis employed minimum inhibitory concentration assays (MICs) to identify PPMOs capable of...
