Use Of Monoclonal ∆-9-Tetrahydrocannabinol Antibodies Chemically Bound To A Polystyrene Surface Using Glutaraldehyde For The Purpose Of Extracting ∆-9-Tetrahydrocannabinol And ∆-9-Tetrahydrocannabinol Carboxylic Acid From Postmortem Whole Blood Samples For Analysis By Gas Chromatography Mass Spectrometry, Thomas Sidney Pittman

Dissertations

Quantitations of drugs and their respective metabolites in postmortem blood samples using gas chromatographic instrumentation is a primary analytical practice used to determine if drugs played a role in or were the cause of a victim's death. Postmortem blood samples often prove difficult to work with due to interfering substances formed during the putrefaction process. Attempts to eliminate interfering substances with present day extraction methods can be time-consuming, costly and often ineffective when dealing with drugs that exhibit toxicity or impairment at very low concentrations. This study was conducted using monoclonal antibodies chemically bound to a polystyrene surface to extract …

Cannabinoids: A Novel Treatment Strategy For Retinal Neurodegenerative Disorders, Sandeep Samudre

Theses and Dissertations in Biomedical Sciences

Synthetic and naturally occurring cannabinoids are known to decrease intraocular pressure (IOP). Glaucomatous damage to the retina and optic nerve progresses even after therapy to maintain normal intraocular pressure (IOP). Topical application of cannabinoids decreases IOP while not affecting blood pressure or heart rate. Based upon their effects on other tissues, we hypothesize that these analogs reduce IOP and may also confer direct neuroprotective effects on the retina, possibly via CB1 and/or CB2 receptors. The purpose of this study is to determine if the newly synthesized CB agonists, lipid soluble O-1812 (CB 1), and water soluble O-2545 (CB 1

Three Models Of Anthrax Toxin Effects On The Map-Kinase Pathway And Macrophage Survival, Daniel J. Schneider

Theses and Dissertations

Lethal factor (LF), a component of anthrax toxin, is the primary virulence factor that allows Bacillus anthracis to evade the immune response by blocking the activation of mitogen-activated protein kinase (MAPK) enzymes. This research modifies three published MAPK models to reflect this signal inhibition and to estimate a first-order reaction rate by fitting the models to published viability data for two macrophage cell lines cultured with the LF-producing Bacillus anthracis-Vollum1B strain. One model appears to be ill-suited for this purpose because not all relevant MAPK components could be integrated into the inhibition equations. Despite different underlying parameters and values, the …

In Vitro Toxicity Of Aluminum Nanoparticles In Human Keratinocytes, Stephanie Mccormack-Brown

Theses and Dissertations

Nanotechnology promises to be the defining technology of the 21st century. At an annual investment of $1B, it provides significant contributions to manufacturing, medicine, energy conservation, and the environment. Nanoparticles are structures with at least one dimension in the 1 to 100 nanometer (nm) range. DoD and US Air Force interest in aluminum nanoparticles (AL NPs) stems from its ability to enhance combustion jet fuel, thus increasing fuel efficiency. The addition of AL NPs to JP-8 may pose a unique dermal hazard to aircraft maintenance workers. There is no published data on AL NP toxicity effects on human skin. This …

Factors That Influence The Distribution Of Antibiotic Resistant Bacteria In The Mud River, Wv, Timothy Shaun Dotson

Theses, Dissertations and Capstones

Background: Prior studies of the Ohio and Mud Rivers have shown that fecal contamination alone does not explain the distribution of antibiotic resistant bacteria (ARB) in surface waters. The objectives of this study were to determine effects on the distribution of ARB in the Mud.

Methods: Water samples and physical parameters were collected twice per season in spring through fall at 12 sites on the Mud River. Aliquots were plated on R2A agar and R2A agar plus individual antibiotics for the enumeration of total cultivable bacteria, and cultivable bacteria resistant to ciprofloxacin, virginiamycin, or tetracycline respectively. The IDEXX Quanti-Tray/2000™ method …

The Evaluation Of Midazolam On Head Injured Patients In The Prehospital Setting, Dragana Klinac

Theses: Doctorates and Masters

Midazolam (Hypnovel ®) is the only sedating agent used by paramedics at St John Ambulance Service W.A. in the management of many conditions including seizure activities, antisocial or uncontrollable behaviours, back pain incidents and head injuries. Midazolam, with a rapid absorption, fast onset of action and short duration on neurological activity, has been accepted as a safe and effective agent in prehospital treatment since the late-1990s. Often, if a patient is not complying with treatment or is uncontrollable or aggressive, paramedics are required to sedate the individual. This study primarily examines the use of midazolam for the sedation of unmanageable …
