Advancements in collection and analysis of fire debris-improved field collection kits with fast gas chromatography
Stuart, Mary E. (2023-05)Gas chromatography with mass spectrometry (GC-MS) is the primary tool used in fire debris analysis by forensic scientists. Improving the efficiency of this analysis through fast GC was the first aim of this work, and it ... -
Automation of a Human DNA Quantification Technique Using a Biomek 2000 Robotic Platform
Duvall, Eric Jon (Oklahoma State University, 2008-12-01)Increases in entry criteria for CODIS entry coupled with advances in forensic DNA typing have caused a nationwide backlog of samples for processing. The purpose of this study was to automate a novel quantitation assay ... -
Cannabinoid distribution and postmortem redistribution in rabbits following controlled cannabis administration
Cliburn, Kacey D. (2021-05)Millions of people in the world use Cannabis sativa for its mood-altering properties. The main psychoactive component of cannabis, delta^9-tetrahydrocannabinol (THC) is commonly detected in forensic toxicology laboratories ... -
Cannabinoids in oral fluid: Limiting potential sources of cannabidiol conversion to Delta 9 - and Delta 8 - tetrahydrocannabinol
Coulter, Cynthia (2021-07)In late 2019, the National Laboratory Certification Program (NLCP) published an article reporting on the potential analytical conversion of 7-carboxy-cannabidiol (CBD-COOH) to 11-nor-9-carboxy-Delta9-tetrahydrocannabinol ... -
Characterization of Clandestine One Pot Methamphetamine Laboratories Using Gas Chromatography-mass Spectrometry and Liquid Chromatography-tandem Mass Spectrometry
Ciesielski, Austin Lee (2017-05-01)Since first being seized in 2007, One Pot meth labs have quickly grown to become the number one route of methamphetamine production across the United States. While One Pot meth labs account for 98% of all clandestine labs ... -
Characterization of fentanyl headspace using solid phase microextraction and gas chromatography-mass spectrometry
Brink, Aubrey Nicole (2021-12)With an increased potency and widespread abuse in recent years, the unknowing exposure to fentanyl has become a growing public safety concern. Even though it has been one of the most frequently encountered opioids since ... -
Characterization of fentanyl headspace using solid phase microextraction: Effects of sampling height and humidity at fixed volume and temperature
Cothran, Gwendolyn Grace (2023-05)The rapid increase in illicit manufacturing of fentanyl and deaths due to fentanyl overdoses within the past few years has led to concerns for the safety of individuals unknowingly encountering it. In order to develop safer ... -
Comparative Study of the Use of a Rapid Thermal Cycler Philisa Versus the Geneamp Pcr System 9700 on Forensically Relevant Samples
Henry, Fernanda (Oklahoma State University, 2013-07-01)Traditional PCR methods for amplification of multiplex STR systems typically take 3-4 hours, due to the limitations of the Taq DNA polymerase and the thermal cyclers used for amplification. Heat-stable, `fast' polymerases, ... -
Comparative Study of Touch Dna Recovery from Metals
Tucker, Kambra Lynn (2015-07-01)Touch DNA requires a special collection approach to recover the minute amounts of DNA left behind in skin cells. Touch DNA has been successfully recovered from surfaces such as fabric, plastic and wood. However, a consistent ... -
Comparison of Sample Preparation Methods for Forensic Opiate Analysis by Liquid Chromatograph-tandem Mass Spectrometry (Lc/ms/ms)
Windham, Melissa (Oklahoma State University, 2013-12-01)Qualitative and quantitative methods for the analysis of opiates on the liquid chromatograph-tandem mass spectrometer (LC/MS/MS) were developed and validated. The qualitative method was developed for the analysis of seven ... -
Detection of prescription and illicit drugs in waste water during sporting events
Ridge, Zachary Dylan (2019-12)Wastewater epidemiology is a noninvasive tool that uses wastewater as a means to gather nondiscriminatory information about the exposure of a group of people to drugs, toxins, and diseases, which is accomplished by analyzing ... -
Development of a Lc-ms/Ms Method to Detect and Quantify Pyridostigmine in Plasma
Sloan, Maegen (2017-05-01)Pyridostigmine is a reversible acetylcholinesterase inhibitor that has been used to help treat myasthenia gravis and reduce nerve agent effects. By reversibly binding to acetylcholinesterase, Pyridostigmine causes elevation ... -
Identifying life history traits in modern and extinct archosaurs utilizing osteohistology
Heck, Christian T. (2022-05)Interpreting dinosaur life history traits is reliant upon data from modern taxa and large, ontogenetically variable dinosaur samples. Recent advances in the study of osteohistology have increased our understanding of ... -
Liquid Chromatography-tandem Mass Spectrometry of Fire Debris Evidence at Suspected Clandestine Methamphetamine Laboratories
