Sensitization Of Human Cancer Cells To Gemcitabine By The Chk1 Inhibitor Mk-8776: Cell Cycle Perturbation And Impact Of Administration Schedule In Vitro And In Vivo, Ryan Montano, Ruth Thompson, Injae Chung, Huagang Hou, Nadeem Khan, Alan Eastman
Dartmouth Scholarship
Chk1 inhibitors have emerged as promising anticancer therapeutic agents particularly when combined with antimetabolites such as gemcitabine, cytarabine or hydroxyurea. Here, we address the importance of appropriate drug scheduling when gemcitabine is combined with the Chk1 inhibitor MK-8776, and the mechanisms involved in the schedule dependence.
Investigation Of The Structure And Dynamics Of Regioisomeric Eu³⁺ And Gd³⁺ Chelates Of Nb-Dotma: Implications For Mri Contrast Agent Design, Benjamin Charles Webber
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 …

Wash Education: Need For More Than Water Treatment For Floating Villages In Cambodia, Kevin Curry
2013 New England Association for Asian Studies Conference
Point of use (POU) water treatment systems are widely used around the world to provide microbiologically safe drinking water in developing countries. Work done in Cambodia by Brown et al. (2007) and Liang et al. (2010) have documented ceramic and biosand filters as cost effective point of use treatment systems capable of removing over 95% E. coli bacteria when properly used and maintained. Bridgewater State University and Water for Cambodia (WfC) explored using BioSand filters (BSF) to provide microbiologically safe drinking water for people in the Moat Khla floating village on the Tonle Sap Lake in Siem Reap Province. All …

Prolactin And Fmri Response To Skf38393 In The Baboon, Brad D. Miller, Lauren A. Marks, Jonathan M. Koller, Blake J. Newman, G Larry Bretthorst, Kevin J. Black
Kevin J. Black, MD
Background: This study’s goal was to provide dose-response data for a dopamine agonist in the baboon using standard methods (replicate measurements at each dose, across a range of doses), as a standard against which to subsequently validate a novel pharmacological MRI (phMRI) method. Dependent variables were functional MRI (fMRI) data from brain regions selected a priori, and systemic prolactin release. Necessary first steps included estimating the magnitude and time course of prolactin response to anesthesia alone and to various doses of agonist. These first steps (“time course studies”) were performed with three agonists, and the results were used to select …

Seizure Protection By Intrapulmonary Delivery Of Midazolam In Mice, Ashish Dhir, Dorota Zolkowska, Michael A. Rogawski
Michael A. Rogawski
The lung provides a portal of entry that could be used to rapidly deliver anticonvulsant substances to the brain to treat seizures. In the present study, we demonstrate that midazolam, a water-soluble anticonvulsant benzodiazepine, confers potent seizure protection when administered via the intrapulmonary route. High dose (100 mg/kg) intraperitoneal midazolam induced loss-of-righting reflex in mice. Lower doses of midazolam (100–1000 μg/kg) when administered intraperitoneally did not induce loss-of-righting reflex but protected animals against pentylenetetrazol (PTZ)-induced seizures. Intrapulmonary administration of midazolam via a tracheal cannula protected against intraperitoneal PTZ seizures at lower doses. The minimal intraperitoneal and intravenous doses of midazolam …

Long-Lasting Attenuation Of Amygdala-Kindled Seizures After Convection-Enhanced Delivery Of Botulinum Neurotoxins A And B Into The Amygdala In Rats, Maciej Gasior, Rebecca Tang, Michael A. Rogawski
Michael A. Rogawski
Botulinum neurotoxins (BoNTs) are well recognized to cause potent, selective and long-lasting neuroparalytic actions by blocking cholinergic neurotransmission to muscles and glands. There is evidence that BoNT isoforms can also inhibit neurotransmission in the brain. Here we examined whether locally delivered BoNT/A and BoNT/B can attenuate kindling measures in amygdala-kindled rats. Male rats were implanted with a combination infusion cannula-stimulating electrode assembly into the right basolateral amygdala. Fully-kindled animals received a single infusion of vehicle or BoNT/A or BoNT/B at doses of 1, 3.2, or 10 ng over a 20-min period by convection enhanced delivery (CED). Electrographic (EEG) and behavioral …
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 …

This report represents a summary of the discussions led by the antiseizure treatment working group of the International League Against Epilepsy (ILAE)/American Epilepsy Society (AES) Working Groups joint meeting in London (London Meeting). We review here what is currently known about the pharmacologic characteristics of current models of refractory seizures, both for adult and pediatric epilepsy. In addition, we address how the National Institute of Neurological Disorders and Stroke (NINDS)-funded Anticonvulsant Screening Program (ASP) is evolving to incorporate appropriate animal models in the search for molecules that might be sufficiently novel to warrant further pharmacologic development. We also briefly address …

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

Despite advances in cancer detection and prevention, a diagnosis of metastatic disease remains a death sentence due to the fact that many cancers are either resistant to chemotherapy (conventional or targeted) or develop resistance during treatment, and residual chemoresistant cells are highly metastatic. Metastatic cancer cells resist the effects of chemotherapeutic agents by upregulating drug transporters, which efflux the drugs, and by activating proliferation and survival signaling pathways. Previously, we found that c-Abl and Arg non-receptor tyrosine kinases are activated in breast cancer, melanoma, and glioblastoma cells, and promote cancer progression. In this report, we demonstrate that the c-Abl/Arg inhibitor, …

School of Natural Resources: Faculty Publications
A secondary analysis of 1999–2002 Nebraska case-control data was conducted to assess the risk of non-Hodgkin lymphoma (NHL) associated with exposure to nitrate- and atrazine-contaminated drinking water. Water chemistry data were collected and weighted by well contribution and proximity of residence to water supply, followed by logistic regression to determine odds ratios (OR) and 95% confidence intervals (CI). We found no association between NHL risk and exposure to drinking water containing atrazine or nitrate alone. Risk associated with the interaction of nitrate and atrazine in drinking water was elevated (OR, 2.5; CI, 1.0–6.2). Risk of indolent B-cell lymphoma was higher …
Psychologists And Medications In The Era Of Interprofessional Care: Collaboration Is Less Problematic And Costly Than Prescribing, William N. Robiner, Tim R. Tumlin, Tanya Tompkins
Psychologists And Medications In The Era Of Interprofessional Care: Collaboration Is Less Problematic And Costly Than Prescribing, William N. Robiner, Tim R. Tumlin, Tanya Tompkins
Faculty Publications
Increasing emphasis on interprofessionalism and teamwork in healthcare renders psychologists’ collaborations critical and invites reexamination of psychologists’ roles related to medications. The Collaboration Level outlined by the APA’s Ad Hoc Task Force is more achievable and in synch with health reform than prescription privileges (RxP). RxP remains controversial due to training and safety concerns, lacking support from health professionals, psychologists, and consumers. Differences in educational preparation of psychologists relative to prescribing professionals are discussed. Enactment of only three of 170 RxP initiatives reveals RxP to be a costly, ineffectual agenda. Alternatives (e.g., integrated care, collaboration, telehealth) increase access without risks …

Abstract
Background
Previous whole-genome shotgun bisulfite sequencing experiments showed that DNA cytosine methylation in the honey bee (Apis mellifera) is almost exclusively at CG dinucleotides in exons. However, the most commonly used method, bisulfite sequencing, cannot distinguish 5-methylcytosine from 5-hydroxymethylcytosine, an oxidized form of 5-methylcytosine that is catalyzed by the TET family of dioxygenases. Furthermore, some analysis software programs under-represent non-CG DNA methylation and hydryoxymethylation for a variety of reasons. Therefore, we used an unbiased analysis of bisulfite sequencing data combined with molecular and bioinformatics approaches to distinguish 5-methylcytosine from 5-hydroxymethylcytosine. By doing this, we have performed the first whole …
Linking Environmental Toxicant Exposure To Diabetes Susceptibility, Jannifer Beth Tyrrell
Linking Environmental Toxicant Exposure To Diabetes Susceptibility, Jannifer Beth Tyrrell
Wayne State University Dissertations
An important and unresolved question in the environmental health field is whether exposure to common environmental toxicants, such as dioxin and heavy metals like Pb, increase the risk of developing diabetes, especially in combination with other common metabolic stressors such as obesity.
Previous studies suggested that dioxin exposure increased peripheral insulin resistance but did not appear to cause fasting hyperglycemia or elevated hepatic glucose output. In concordance with those findings we observed that dioxin treatment caused a strong suppression of the expression of the key hepatic gluconeogenic genes PEPCK and G6Pase. However, this suppression was not solely mediated by the …
The Effect Of Alpha-Cyclodextrin On Acute Blood Lipid And Glycemic Responses To A Fat Containg Meal, Evan Neil Fletcher
The Effect Of Alpha-Cyclodextrin On Acute Blood Lipid And Glycemic Responses To A Fat Containg Meal, Evan Neil Fletcher
Wayne State University Theses
Obesity and hyperlipidemia have become major concerns in the United States over the past 30 years. Alpha-Cyclodextrin (á-CD), a naturally occurring soluble dietary fiber, has been shown to reduce dietary fat absorption and improve blood lipid levels in an animal model (mouse and rat) and in human studies. In the current double blind study, 34 healthy male and female participants were recruited to test if á-CD had any acute effect on blood lipid and glycemic responses to a fat containing meal. The participants received the á-CD on one occasion and a placebo the other to determine if there was any …
Could You Repeat That Please? Forty-Five Years Of Testing Pesticides On People, Barbara R. Leiterman Esq.
Could You Repeat That Please? Forty-Five Years Of Testing Pesticides On People, Barbara R. Leiterman Esq.
Barbara R. Leiterman Esq.
Little has been published in the literature about pesticide experiments conducted on human subjects. Yet there were at least twenty-two tests between 1967 and 2011 in which people were intentionally exposed to specific doses of pesticides. Almost all of these experiments violated scientific ethics and human rights. This article aims to describe those tests and their shortcomings, and explore the laws and regulations that incentivize such human experimentation. Ironically, as the public desire for pesticide safety increases, so does the industry’s motivation to test pesticides on people. Bringing these pesticide experiments to light, expanding the public discourse on the subject …
Toxicological Effects Of Cerium Oxide Nanoparticle Aggregates On Caenorhabditis Elegans, Steven N. Rogers
Toxicological Effects Of Cerium Oxide Nanoparticle Aggregates On Caenorhabditis Elegans, Steven N. Rogers
Theses, Dissertations and Capstones
Assessing the toxicity and unique reactivity of nanoparticles in biological systems has become an relevant and quickly growing area of environmental toxicology research. The broad use of nanoparticles in industrial and commercial commodities results in exposure of these nano-compounds to the environment, the ecosystems, and humans. While previous data has suggested that cerium oxide (CeO2) nanoparticles are relatively safe to cultured cells much less is known about the potential toxicity of these materials at the organismal level. In this study we employed transgenic Caenorhabditis elegans (C. elegans) strains to assess the toxicity of CeO2 nanoparticles under “real-world” …
