Nudging The Fda, W. Nicholson Price Ii, I. Glenn Cohen

Law Faculty Scholarship

[Excerpt] "The FDA’s regulation of drugs is frequently the subject of policy debate, with arguments falling into two camps. On the one hand, a libertarian view of patients and the health care system holds high the value of consumer choice. Patients should get all the information and the drugs they want; the FDA should do what it can to enforce some basic standards but should otherwise get out of the way. On the other hand, a paternalist view values the FDA’s role as an expert agency standing between patients and a set of potentially dangerous drugs and potentially unscrupulous or …

Integrating Phage Therapy Into Western Medicine, Jacob B. Jaminet

UROP Posters

The World Health Organization has described the rise of antibiotic use as a “global heath security emergency” (who.int). With the growing concern about antibiotic resistant bacteria, there has been an increased interest in bacteriophages. Bacteriophages are high-specific viruses that only infect bacteria. The use of bacteriophages medicinally to treat bacteria is called phage therapy. Research in phage therapy gained momentum until the introduction of antibiotics. While the USA and other Western countries accepted antibiotics, the Soviet Union and their satellite nations still continued to research phages. Since the funding for research was supplied by the Soviet military, the results of …

The Effects That Liquid And Solid Cattle Manure Have On The Water Quality Of Drainage Ditches In Putnam County, Ohio, Janelle Horstman

Honors Projects

Lake Erie has experienced harmful algal blooms with increased frequency since the mid-1990s due to excess nutrients from Rivers, such as the Maumee River, and largely agricultural watersheds. Nonpoint source pollution from agriculture contributes to eutrophication, algal blooms, and the degradation of water quality. This creates stress on aquatic fauna, reduced aesthetic quality, odor, and limits of the water for usage of drinking, recreation, and industry. This research paper asks what the contributions of having access to manure application records, soil records, and information about antibiotics have on what is known about manure management and antibiotic resistance, which has been …

Effects Of Anti-Inflammatory Foods On Hyperglycemia In Type-1 Diabetics, Primrose Martin, Michelle Chino

McNair Poster Presentations

Based on a case study administered by Dr. Charlotte Gerson, an IDDM patient referred to as R.H. reversed hyperglycemic symptoms within ten weeks while adhering to a diet of mainly vegetables and some low-glycemic index fruits. R.H. also ingested mineral supplements and underwent multiple coffee enemas each day (Gerson & Bishop, 2007, p. 56). This self-study hypothesizes that diet alone has a positive correlation coefficient with hyperglycemic blood glucose levels in type-1 diabetics (IDDM). Conducting this self-study contributes information to the limited research and database of alternative methods for managing IDDM hyperglycemia, and provides candid documentation of the effects that …

Dj-1 And Atp13a2: Two Proteins Involved In Parkinson’S Disease, Josephat M Asiago

Open Access Dissertations

Parkinson's disease (PD) is the second most common neurodegenerative disorder after Alzheimer's disease, affecting approximately 0.3% of the total U.S. population, and its prevalence increases with age. Two neuropathological hallmarks of PD are the loss of dopaminergic neurons in the substantia nigra pars compacta, a region in the midbrain involved in initiating and sustaining movement, and the presence of cytosolic inclusions called Lewy bodies (LBs) in various brain regions. LBs are enriched with fibrillar forms of the presynaptic protein &agr;-synuclein (aSyn). Two autosomal recessive genes implicated in familial PD are PARK9, encoding the P-type ATPase ATP13A2, a lysosomal ATPase; and …

Atrazine In Maternal Drinking Water Supply Below The Federal Maximum Contaminant Level And Risk Of Preterm Birth, Small For Gestational Age, Cryptorchidism And Hypospadias, Daniel Rice

Legacy Theses & Dissertations (2009 - 2024)

The prevalence of preterm birth, small for gestational age (SGA), and hypospadias has been increasing for several decades in the U.S resulting in significant morbidity and mortality and direct costs to society. Drinking water provides a mechanism for prolonged chronic exposure to environmental contaminants but is one of the least assessed environmental exposures in pregnancy and birth outcomes. To test the hypothesis that maternal exposure to atrazine through drinking water during pregnancy, or one or more trimesters of gestation, is associated with an increased risk of preterm birth, small for gestational age, cryptorchidism and hypospadias a retrospective cohort study was …

Perfluorinated Compounds, Thyroid Function, And Neuropsychological Status In Older Residents Of Upper Hudson River Communities, Srishti Shrestha

Legacy Theses & Dissertations (2009 - 2024)

Perfluorinated compounds (PFCs) are widespread in the environment. Minimal data exist regarding the neurotoxicity and thyroid disruptive property of PFCs in aging populations and the possible mediating effects of thyroid hormones (THs). In this study, we assessed associations among PFCs, thyroid function, and neuropsychological status, and determined if the neurotoxic effects of PFCs are mediated by changes in THs in an aging population. We measured perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS), thyroid stimulating hormone (TSH), total thyroxine (T4), free T4 (fT4), and total triiodothyronine (T3) in serum and performed neuropsychological tests in men and women aged 55-74 years and living …

Exposure Assessment And Risk Management Of Engineered Nanoparticles : Investigation In Semiconductor Wafer Processing, Michele Shepard

Legacy Theses & Dissertations (2009 - 2024)

Engineered nanomaterials (ENMs) are currently used in hundreds of commercial products and industrial processes, with more applications being investigated. Nanomaterials have unique properties that differ from bulk materials. While these properties may enable technological advancements, the potential risks of ENMs to people and the environment are not yet fully understood. Certain low solubility nanoparticles are more toxic than their bulk material, such that existing occupational exposure limits may not be sufficiently protective for workers. Risk assessments are currently challenging due to gaps in data on the numerous emerging materials and applications as well as method uncertainties and limitations.

Runner Identity And Sponsorship: Evaluating The Rock ‘N’ Roll Marathon, Nancy L. Lough, Jennifer Pharr, Jason O. Owen

Environmental & Global Health Faculty Research

The economic value of participation sport has been reported to eclipse spectator sport significantly. However, scholars have acknowledged the relative lack of research on this important segment of the sport market. The purpose of this study was to analyze the relationship between runner identity and race sponsor effectiveness. Surveys were sent to participants in the Las Vegas Rock ‘n’ Roll Marathon. The survey was constructed to measure runner identity, and sponsor effectiveness as interpreted through rates of recognition, recall and purchase intention.

Parent-Metabolite Pharmacokinetic Models For Tramadol – Tests Of Assumptions And Predictions, Sam Holford, Karel Allegaert, Brian J. Anderson, Butch Kukanich, Altamir B. Sousa, Amir Steinman, Bruno Pypendop, Reza Mehvar, Mario Giorgi, Nick Holford

Pharmacy Faculty Articles and Research

Allometric principles were used to discern cross-species differences in (±)-tramadol disposition and formation of its primary analgesic metabolite, (±)-O-desmethyl-tramadol (M1). Species differences in formation of M1 may help predict the analgesic effectiveness of tramadol. Tramadol was administered intravenously by a zero-order (constant infusion) process or rapid bolus dose and racemic concentrations of tramadol and M1 measured. Data were pooled to define differences between species (human, rat, cat, dog, goat, donkey and horse). A two-compartment linear disposition model with first-order elimination was used to describe tramadol and M1 disposition. Slow metabolizers were detected in 6% of the population and tramadol clearance …

Flavonoids With Novel Nicotinic Activity As Potential Pharmacotherapies To Treat Ethanol-Induced Neurotoxicity, Joseph A. Lutz

Theses and Dissertations--Pharmacy

Ethanol causes neurotoxicity via several mechanisms at different points in the cycle of dependence, including neuroinflammation and oxidative stress during ethanol exposure as well as excitotoxicity during ethanol withdrawal. The primary therapeutic implication is that ethanol-induced neurotoxicity requires multifunctional pharmacotherapies which reduce all mechanisms. Using an innovative pharmacological high throughput screening method on a large plant extract library we discovered flavonoids with alpha7 nicotinic acetylcholine receptor (nAChR) activity. In addition to their well-known anti-inflammatory and antioxidant properties, this novel activity means they can potentially reduce excitotoxicity and therefore makes them ideal for inhibition of ethanol-induced neurotoxicity. Rhamnetin, the candidate compound, …

Phosphatidylinositol 3-Kinase (Pi3k) As A Therapeutic Target In Nsclc, Christopher W. Stamatkin

Theses and Dissertations--Pharmacy

Deregulated activation of phosphatidylinositol 3-kinase (PI3K) pathway is central to many human malignancies. The functions of this pathway are critical for normal cell metabolism, proliferation, and survival. In lung cancers, the PI3K pathway activity is often aberrantly driven by multiple mutations, including EGFR, KRAS, and PIK3CA. Molecules targeting the PI3K pathway are intensely investigated as potential anti-cancer agents. Although inhibitors of the pathway are currently in clinical trials, rational and targeted use of these compounds, alone or in combination, requires an understanding of isoform-specific activity in context. We sought to identify class IA PI3K enzyme (p110a/PIK3CA, p110b/PIK3CB, p110d/PIK3CD) activities using …

Β-Lactam Estrogen Receptor Antagonists And A Dual-Targeting Estrogen Receptor/Tubulin Ligand, Niamh O'Boyle, Jade K. Pollock, Miriam Carr, Andrew Js Knox, Seema M. Nathwani, Shu Wang, Laura Caboni, Daniela M. Zisterer, Mary Meegan

Articles

Twelve novel β-lactams were synthesised and their antiproliferative effects and binding affinity for the predominant isoforms of the estrogen receptor (ER), ERα and ERβ, were determined. β-Lactams 23 and 26 had the strongest binding affinities for ERα (IC₅₀ values: 40 and 8 nM respectively) and ERβ (IC₅₀ values: 19 and 15 nM). β-Lactam 26 was the most potent in antiproliferative assays using MCF-7 breast cancer cells, and further biochemical analysis showed that it caused accumulation of cells in G₂/M phase (mitotic blockade) and depolymerisation of tubulin in MCF-7 cells. Compound 26 also induced apoptosis and downregulation …

Investigation Of The Structure And Dynamics Of Regioisomeric Eu³⁺ And Gd³⁺ Chelates Of Nb-Dotma: Implications For Mri Contrast Agent Design, Benjamin Charles Webber

Dissertations and Theses

The detection of disease and abnormal pathology by magnetic resonance imaging (MRI) has been aided significantly by the use of gadolinium (Gd³⁺)-based contrast agents (CAs) over the past three decades. MRI and MRI CAs play a critical role in diagnosing tumors and diseases of the central nervous system. The agents used clinically have been shown to safely increase MRI contrast despite the toxicity of Gd³⁺, owing to the high kinetic and thermodynamic stability of these chelates. However, current CAs enhance contrast at a small fraction of what is theoretically possible. This leads to the necessity of …

Non-Mass Transfer Limited Crystal Growth, Ryan J. Smyth, Caitlin Schram, Stephen P. Beaudoin

The Summer Undergraduate Research Fellowship (SURF) Symposium

There are many different active pharmaceutical ingredients (APIs) that have been discovered in research labs all around the world that can be used to treat and cure patients with a variety of different ailments. The challenge with these APIs in treatments is that they are not soluble in water, thus they low absorption into the blood stream (bio-availability). The key to making these APIs more bio-available is to understand how they grow as crystals and drop out of the aqueous solutions. One of the ways these APIs were made more bio-available is to render them amorphous and suspend them in …

Juxtaposing Nasa’S Aeronet Aod With Carb Pm Data Over The San Joaquin Valley To Facilitate Multi-Angle Imaging Spectroradiometer (Misr) Pm Pollution Research, John Kanemoto

STAR Program Research Presentations

Airborne particulate matter (PM) has been shown to increase the risk for asthma, chronic bronchitis, cardiopulmonary complications, and respiratory cell membrane damage/infection/leakage. PM levels are currently analyzed from two perspectives: stationary land-based monitoring (LBM) sites and total Aerosol Optical Depth (AOD) atmospheric column measurements. Both perspectives often leave miles of space between measuring locations and will have a continually increasing cost from introducing/maintaining sites. The Multi-angle Imaging SpectroRadiometer (MISR) satellite team hopes to begin investigating/archiving PM levels comprehensively via inputting MISR AOD measurements into a function/model which predicts the amount of ground level PM.

In the future, multivariable spatial correlations …

Liposomal Fasudil, A Rho-Kinase Inhibitor, For Prolonged Pulmonary Preferential Vasodilation In Pulmonary Arterial Hypertension, Vivek Gupta, Nilesh Gupta, Imam H. Shaik, Reza Mehvar, Ivan F. Mcmurty, Masahiko Osa, Eva Nozik-Grayck, Fakhrul Ahsan

Pharmacy Faculty Articles and Research

Current pharmacological interventions for pulmonary arterial hypertension (PAH) require continuous infusions, multiple inhalations, or oral administration of drugs that act on various pathways involved in the pathogenesis of PAH. However, invasive methods of administration, short duration of action, and lack of pulmonary selectivity result in noncompliance and poor patient outcomes. In this study, we tested the hypothesis that encapsulation of an investigational anti-PAH molecule fasudil (HA-1077), a Rho-kinase inhibitor, into liposomal vesicles results in prolonged vasodilation in distal pulmonary arterioles. Liposomes were prepared by hydration and extrusion method and fasudil was loaded by ammonium sulfate-induced transmembrane electrochemical gradient. Liposomes were …

The Effects Of Selected Drugs On The Memory Recall Of Sleep Deprived Mice, Jenn Pauldurai

Capstone Research Projects

Humans often make use of the neurotransmission altering effects of drugs such as caffeine, ephedrine, and ethanol. These drugs induce changes in memory and learning ability, specifically when used for sleep deprivation. English white mice (Mus musculus) have been shown to exhibit similar cognitive changes when administered drugs while sleep deprived. A sample of 20 mice was divided into three experimental groups (each group receiving a different drug) and one control group. Maze-testing demonstrated that mice performance decreased with sleep deprivation (Treatment-1) but all groups returned to baseline performance when injected (IP) with selected drugs (Treatment-2), regardless of …
