Biological Evaluation Of Cyclooxygenase-2 Inhibitor Nimesulide Derivatives As Anti-Agents, Amandeep Singh, Snigdha Chennamaneni Sep 2012

Biological Evaluation Of Cyclooxygenase-2 Inhibitor Nimesulide Derivatives As Anti-Agents, Amandeep Singh, Snigdha Chennamaneni

Undergraduate Research Posters 2012

Cyclooxygenase-2 (COX-2) inhibitor nimesulide inhibits the proliferation of various types of cancer cells mainly via COX-2 independent mechanisms, which makes it a good lead compound for anti-cancer drug development. A series of new nimesulide analogs were evaluated with cell proliferation assay based on a non-small lung cancer cell line H292. The results showed that several derivatives were very active to against H292 cell growth with IC50s of sub nano mole. These results suggest the possibility of using these nimesulide derivatives as chemo preventive agents.


Nrf2 Activation By Dimercaptopropanol Attenuates Mutant Huntingtin Toxicity, Kyle M. Dailey Aug 2012

Nrf2 Activation By Dimercaptopropanol Attenuates Mutant Huntingtin Toxicity, Kyle M. Dailey

Electronic Thesis and Dissertation Repository

Huntington’s disease (HD) is a fatal neurodegenerative disorder resulting from the expansion of a trinucleotide repeat within the HD gene. At the cellular level mutant HTT (mHTT) aggregates perturb cellular metabolism, intracellular trafficking and mitochondrial function, resulting in the increased production of reactive oxygen species (ROS) an event closely linked with nerve cell death. Nuclear factor erythroid 2-related factor 2 (NRF2) is a redox-sensitive transcription factor responsible for transcribing neuroprotective genes under the control of the antioxidant response element (ARE), which work to counteract high intracellular ROS levels. I have identified significant increases in cell viability, NRF2 nuclear localization, and …


System Dynamics Modeling Of Medical Use, Nonmedical Use And Diversion Of Prescription Opioid Analgesics, Wayne W. Wakeland, Teresa D. Schmidt, J. David Haddox Jul 2012

System Dynamics Modeling Of Medical Use, Nonmedical Use And Diversion Of Prescription Opioid Analgesics, Wayne W. Wakeland, Teresa D. Schmidt, J. David Haddox

Wayne W. Wakeland

A dramatic rise in the nonmedical of pharmaceutical opioids has presented the United States with a substantial public health problem. Nonmedical use of prescription pain relievers has become increasingly prevalent in the US over the last two decades, and diversion of medicines obtained by prescription is assumed to be a major source of supply for nonmedical opioid use. Policymakers striving to protect population health by ameliorating the adverse outcomes of nonmedical use of opioid analgesics could benefit from a systems-level model which reflects the complexity of the system and incorporates the full range of available data. To address this need, …

Systems Science Faculty Publications and Presentations

The objective of the study was to develop a system dynamics model of the medical use of pharmaceutical opioids to treat pain, and the associated diversion and nonmedical use of these drugs. The model was used to test the impact of simulated interventions in this complex system. The study relied on secondary data obtained from the literature and from other public sources for the period 1995 to 2008. In addition, an expert panel provided recommendations regarding model parameters and model structure. The behavior of the resulting systems level model compared favorably with reference behavior data (R2=.95). After the base model …

In February 2011, the Government of Bahrain began targeting health professionals who treated protesters. In April 2012, PHR's Richard Sollom, Deputy Director, and Holly Atkinson, MD, FACP, past President of PHR's Board and volunteer expert, authored a report showing the devastation on Bahrain's health system that have resulted from the Government of Bahrain’s continued assault on doctors, patients, and the healthcare system.


Medical Oxymoron Or Necessary Prevention Of Repeat Sex Offenses: An Examination Of The Appropriateness Of Existing Chemical Castration Statutes, Robert Watters May 2012

Medical Oxymoron Or Necessary Prevention Of Repeat Sex Offenses: An Examination Of The Appropriateness Of Existing Chemical Castration Statutes, Robert Watters

Robert Watters

The current chemical castration statutes in six states are full of logical constitutional, medical and ethical questions and concerns. The basis for the criticism can be traced to how the schemes were developed compared to the those used in Europe. The castration statutes enacted after long trial and error periods are, therefore, easily discernible from those signed into law quickly as a reaction to some outside event.


The Effects Of Nicotine Administration On Behavior And Markers Of Brain Plasticity In A Rodent Model Of Psychosis, Marla K. Perna May 2012

The Effects Of Nicotine Administration On Behavior And Markers Of Brain Plasticity In A Rodent Model Of Psychosis, Marla K. Perna

Electronic Theses and Dissertations

Schizophrenia affects about 1% of the population. A hallmark of the disorder is increased dopamine D2 receptor sensitivity in the brain. Studies have shown that schizophrenics smoke cigarettes at approximately 4 times the rate of the general population. It has been suggested that nicotine use is a form of self-medication for symptoms in schizophrenia. Smoking behaviors typically begin in adolescence. We assessed effects of nicotine on behavior and brain plasticity in an adolescent rodent model of schizophrenia with the goal of identifying targets for smoking cessation. Methods: Rats were neonatally treated with quinpirole (a D2/D3 agonist) or saline and sensitized …


Environmental Friendly Synthesis, Characterization Of Surface Modifiable Starch Encapsulated Gold Nanoparticles With Bactericidal And Catalytic Activity, Dillon Pender May 2012

Environmental Friendly Synthesis, Characterization Of Surface Modifiable Starch Encapsulated Gold Nanoparticles With Bactericidal And Catalytic Activity, Dillon Pender

Mahurin Honors College Capstone Experience/Thesis Projects

In the present study, we report the green synthesis of gold nanoparticles (GNPs), using potato starch as a reducing as well as a stabilizing agent in an aqueous buffer medium. The resulting starch-GNPs (St-GNPs) were near spherical in shape with an average diameter of 15 ± 5 nm. In this approach, St-GNPs were characterized and investigated for their antibacterial properties against both gram negative (Escherichia coli) and gram positive (Staphylococcus epidermidis) bacteria. These St-GNPs were found to possess significant dose dependent antibacterial activity against bacteria. Also, St-GNPs showed a significant catalytic activity and can easily be …

At least seven states have chemical castration statutes to combat recidivist sex offenders. This article is an examination of the appropriateness and effectiveness of those statutes as against the successful European models.


Differential Effects Of Acute Amphetamine And Phencyclidine Treatment And Withdrawal From Repeated Amphetamine Or Phencyclidine Treatment On Social Interaction And Social Memory In Rats, Ming Li, Wei He, Rebecca Munro Jan 2012

Differential Effects Of Acute Amphetamine And Phencyclidine Treatment And Withdrawal From Repeated Amphetamine Or Phencyclidine Treatment On Social Interaction And Social Memory In Rats, Ming Li, Wei He, Rebecca Munro

Department of Psychology: Faculty Publications

Although animal models based on amphetamine (AMPH) or phencyclidine (PCP) treatment have been used extensively to study the neurobiological and behavioral characteristics of schizophrenia, there are conflicting reports regarding their validity in modeling the negative symptoms and cognitive deficits of schizophrenia. The present study examined how acute AMPH or PCP treatment (Experiment 1) and withdrawal from repeated AMPH treatment (Experiment 2) or PCP treatment (Experiment 3) affects social behavior and social recognition memory in male Sprague-Dawley rats. Each subject was tested on two consecutive days. On the first day, the rats were tested four times (5 min/each) at 10-min intervals …

Articles

Diglycidyl ethers of bisphenol A (DGEBA) and bisphenol F (DGEBF) are widely used as components in epoxy resin thermosetting products. They are known to cause occupational and non-occupational allergic contact dermatitis. The aim of this study is to investigate analogues of DGEBF with regard to contact allergy and cytotoxicity. A comprehensive knowledge of the structural features that contribute to the allergenic and cytotoxic effects of DGEBF will guide the development of future novel epoxy resin systems with reduced health hazards for those coming into contact with them. It was found that the allergenic effects of DGEBF were dependent on its …
