Counseling, School Psychology & Sport Faculty Publication Series

Within the past few years, increasing concerns have arisen about the ways in which corporate sponsorship of clinical trials and continuing medical education activities may bias the information that is published and disseminated about the benefits and risks of medications. Questions have also been raised about the extent of industry influence on the American Psychiatric Association’s diagnostic and treatment guidelines—namely, its DSM and Clinical Practice Guidelines.

Organophosphorus Pesticides Decrease M2 Muscarinic Receptor Function In Guinea Pig Airway Nerves Via Indirect Mechanisms, Becky J. Proskocil, Donald A. Bruun, Charles M. Thompson, Allison D. Fryer, Pamela J. Lein

Biomedical and Pharmaceutical Sciences Faculty Publications

Background: Epidemiological studies link organophosphorus pesticide (OP) exposures to asthma, and we have shown that the OPs chlorpyrifos, diazinon and parathion cause airway hyperreactivity in guinea pigs 24 hr after a single subcutaneous injection. OP-induced airway hyperreactivity involves M2 muscarinic receptor dysfunction on airway nerves independent of acetylcholinesterase (AChE) inhibition, but how OPs inhibit neuronal M2 receptors in airways is not known. In the central nervous system, OPs interact directly with neurons to alter muscarinic receptor function or expression; therefore, in this study we tested whether the OP parathion or its oxon metabolite, paraoxon, might decrease M2 receptor function on …

Angiotensin-Converting Enzyme 2: A New Target For Neurogenic Hypertension, Yumei Feng, Huijing Xia, Robson A. Santos, Robert Speth, Eric Lazartigues

HPD Articles

Overactivity of the renin-angiotensin system (RAS) is involved in the pathogenesis of hypertension, and an overactive brain RAS has been highlighted in several genetic and experimental models. Until now, angiotensin II (Ang II) was thought to be the main effector of this system, and the angiotensin-converting enzyme (ACE)-Ang II-Ang II type 1 receptor axis was the main target for antihypertensive therapies. A new member of the RAS, ACE2 (angiotensin-converting enzyme type 2), has been identified in organs and tissues related to cardiovascular function (e.g. heart, kidney and blood vessels) and appears to be part of a counter-regulatory pathway to buffer …

Tamoxifen: Mechanisms Of Resistance, Cyrus Mccoy Adams

Theses and Dissertations (ETD)

The role of estrogen in breast cancer has been recognized for decades. The selective estrogen receptor modulator tamoxifen was the first targeted therapy for the treatment of breast cancer. It was also the first drug approved by the FDA for the reduction of breast cancer risk. While tamoxifen has extended the lives of countless patients with breast cancer, resistance to tamoxifen remains a significant clinical problem. Work over the last two decades has greatly enhanced our understanding of the molecular mechanisms by which breast cancer cells may become resistant to tamoxifen treatment. Here I review our current understanding of the …

The Design And Synthesis Of Novel Antimicrobial Agents For Use In The Battle Against Bacterial Resistance, Joshua Randal Brown

Theses and Dissertations (ETD)

There is an ever increasing need to develop new antimicrobial agents with novel mechanisms of action. These new agents will help to combat the steady rise of antibiotic-resistant bacteria which are becoming more and more difficult to treat due to the dwindling number of antibiotics available to treat such organisms. This body of work brings to light the many ways in which medicinal chemistry plays a vital role in the discovery of novel antimicrobial agents. Chapter 1 is an introduction into antimicrobial agents. It provides a brief history of the discovery of antimicrobial agents, and delves into reasons why new …

Transcriptional Regulation Of Azole Antifungal Resistance And Tolerance In Candida Glabrata, Kelly E. Caudle

Theses and Dissertations (ETD)

Azole antifungal resistance has emerged as a significant problem in the management of infections caused by fungi including Candida species. In recent years, Candida glabrata has become the second most common cause of mucosal and invasive fungal infections in humans second to Candida albicans. Not only are systemic C. glabrata infections characterized by high mortality rates, treatment failures to the azole class of antifungals, the most widely used antifungal for treatment of Candida infections, have been reported. Contributing to this problem, C. glabrata exhibits intrinsic reduced susceptibility to the azole antifungals, and the development of high-level azole resistance …

Population Pharmacokinetics Of Therapeutic Monoclonal Antibodies: Examples And Estimation Method Performance Differences, Nathanael Le Dirks

Theses and Dissertations (ETD)

Over the past two decades, there has been an increase in the research and development and therapeutic application of monoclonal antibodies (mAbs). An application of pharmacokinetic (PK) and pharmacodynamic concepts that has likely contributed to the success of the pre-clinical and clinical drug development of therapeutic mAbs is population PK, which attempts to quantify the typical disposition characteristics and sources of PK variability (such as between-subject, within-subject, and inter-occasion variability) within study populations. Population PK also attempts to identify and quantify the impact of covariates on systemic drug exposure and assess their potential implications for clinical dosing. The general theme …

Synthesis Of Novel Cannabinoid Ligands And Their Use As Anti-Glioma And Anti-Inflammatory Agents, Steven Neal Gurley

Theses and Dissertations (ETD)

Following the discovery of the cannabinoid receptors, research in the field of cannabinoids has grown exponentially over the last two decades. Cannabinoids have been shown to have tremendous therapeutic potential in the treatment of several pathological conditions ranging from inflammation to asthma, multiple sclerosis, Parkinson’s disease, epilepsy, glaucoma, septic shock, hemorrhagic shock, and cancer. Our research has focused on two major conditions for which cannabinoids hold great promise for drug development, namely, cancer and inflammation.

Our focus in the field of cancer has been on the devastatingly lethal brain tumor glioblastoma multiforme. Due to the high expression of the CB2 …

Tdiscovery And Development Of Novel Therapeutic Agents For Advanced Melanoma, Zhao Wang

Theses and Dissertations (ETD)

Malignant melanoma is the most dangerous form of skin cancer and accounts for about 75% of skin cancer deaths. Once diagnosed at the metastatic stage, it has a very poor prognosis with a median survival rate of 6 months and a 5-year survival rate of less than 5%. In addition, melanoma has become an important public health hazard owing to its rising incidence, which has been well documented over the past 50 years. Currently there is no effective way to treat melanoma. It is highly resistant to existing chemotherapy, radiotherapy, and immunotherapy. Over the past 30 years, only two drugs …

Discovery Of Quinic Acid Derivatives As Oral Anti-Inflammatory Agents, Kui Zeng

Theses and Dissertations (ETD)

Quinic acid (QA) esters found in hot water extracts of Uncaria tomentosa (a.k.a. Cat’s claw) exert anti-inflammatory activity through mechanisms involving inhibition of the pro-inflammatory transcription factor nuclear factor kappa B (NF-κB). Herein, we described the synthesis and biological testing of novel QA derivatives. Inhibition of NF-κB was assessed using A549 (Type II alveolar epithelial-like) cells that stably express a secreted alkaline phosphatase (SEAP) reporter driven by an NF-κB response element. A549- NF-κB cells were stimulated with TNF-α (10 ng/mL) in the presence or absence of QA derivative for 18 hours followed by measurement of SEAP activity. Amide substitution at …

Library Synthesis Of Anticancer And Antibacterial Agents Via Azide Chemistry, Jianjun Zhang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Various anticancer and antibacterial agents have been synthesized via azide chemistry by taking advantage of carbohydrate. Starting from the synthesis of 14 glycosyl azides, a library of carbohydrate-oxazolidinone conjugates and a library of carbohydrate-cyclopamine conjugates with biological interests were synthesized based on a highly efficient "click reaction" assisted by sonication. Some of the conjugates have improved solubility and enhanced anticancer activity.

A library of neomycin B derivatives with various modifications at the 5" position has been synthesized. Two leads exhibit prominent activity against both methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE). Antibacterial activities were measured when combined with other …

Hedgehog/Gli Supports Androgen Signaling In Androgen Deprived And Androgen Independent Prostate Cancer Cells, Mengqian Chen, Michael A. Feuerstein, Elina Levina, Prateek S. Baghel, Richard D. Carkner, Matthew J. Tanner, Michael Shtutman, Francis Vacherot, Stéphane Terry, Alexandre De La Taille, Ralph Buttyan

Faculty Publications

Background: Castration resistant prostate cancer (CRPC) develops as a consequence of hormone therapies used to deplete androgens in advanced prostate cancer patients. CRPC cells are able to grow in a low androgen environment and this is associated with anomalous activity of their endogenous androgen receptor (AR) despite the low systemic androgen levels in the patients. Therefore, the reactivated tumor cell androgen signaling pathway is thought to provide a target for control of CRPC. Previously, we reported that Hedgehog (Hh) signaling was conditionally activated by androgen deprivation in androgen sensitive prostate cancer cells and here we studied the potential for cross-talk …

Background: Pandemic influenza poses a serious threat to global health and the world economy. While vaccines are currently under development, passive immunization could offer an alternative strategy to prevent and treat influenza virus infection. Attempts to develop monoclonal antibodies (mAbs) have been made. However, passive immunization based on mAbs may require a cocktail of mAbs with broader specificity in order to provide full protection since mAbs are generally specific for single epitopes. Chicken immunoglobulins (IgY) found in egg yolk have been used mainly for treatment of infectious diseases of the gastrointestinal tract. Because the recent epidemic of highly pathogenic avian …

Pharmaceutical Sciences Faculty Patents

The present invention provides methods and formulations for optimizing the anti-cancer and anti-HIV activities of a camptothecin drug, including camptothecin and its related analogs including 9-aminocamptothecin and 9-nitrocamptothecin. The invention involves methodologies and formulations that limit human serum albumin-mediated reduction of the anti-cancer and anti-HIV effects of the camptothecins, and the methods and formulations provide combination therapies in which binding of the camptothecin agent to human serum albumin can be modulated by the administration of a competing agent that also binds human serum albumin. Reduced camptothecin drug binding to human serum albumin can result in elevated camptothecin free drug levels …

Patient Centered Care Approach To Adherence With Cardiovascular Medications: Self-Determination Theory Integration, David S. Li

Health Services Research Dissertations

Problem statement. Behavioral intervention is used to improve adherence with medication in patients with cardiovascular diseases (CVD), but the effect was not sustainable. Patient-centered care (PCC) as a consumer movement has gained acceptance, but it lacks a theoretical framework. Self-determination theory (SDT) may provide an alternative to improve patients' adherence to chronic cardiovascular medication, as well as a theoretical framework for PCC. Both approaches to CVD management have not been evaluated.

Methods. The study was a quasi-experimental pretest posttest comparison design with consecutive sampling of a hospitalized cardiac patient population. Sixty patients each for the usual care (UC) …

Clinical signs, including derangements of maximum temperature (Tmax), white blood cell (WBC) count, and PaO2/FiO2, were evaluated on days 1–16 after VAP diagnosis. Data are presented as mean ± SD unless otherwise stated. Clinical parameters after VAP …

Virus-Triggered Ubiquitination Of Traf3/6 By Ciap1/2 Is Essential For Induction Of Interferon- &Beta (Ifn-&Beta) And Cellular Antiviral Response, Ai-Ping Mao, Shu Li, Bo Zhong, Ying Li, Jie Yan, Qi Li, Chengwen Teng Pharm.D.. Ph.D, Hong-Bing Shu

Faculty Publications

Viral infection causes activation of transcription factors NF-κB and IRF3, which collaborate to induce type I interferons (IFNs) and cellular antiviral response. Here we show that knockdown of the E3 ubiquitin ligases cIAP1 and cIAP2 markedly inhibited virus-triggered activation of IRF3 and NF-κB as well as IFN-β induction. Knockdown of cIAP1 and cIAP2 also inhibited cytoplasmic dsRNA-triggered cellular antiviral response. Endogenous coimmunoprecipitation experiments indicated that viral infection caused recruitment of cIAP1 and cIAP2 to TRAF3, TRAF6, and VISA. Furthermore, we demonstrated that cIAP1- and cIAP2-mediated virus-triggered ubiquitination of TRAF3 and TRAF6. These findings suggest that virus-triggered ubiquitination of TRAF3 and …

Pharmaceutical Philanthropic Shell Games, Lisa Cosgrove, Harold J. Bursztajn

Counseling, School Psychology & Sport Faculty Publication Series

In response to increasing public distrust and congressional concerns regarding pharmaceutical company influence on medical research and education, professional organizations have taken steps to phase out or regulate industry-sponsored educational support. A related problem is industry funding of philanthropic organizations, such as patient advocacy groups. Thus, when the office of Sen Charles Grassley (R-Iowa) recently reported that the National Alliance for the Mentally Ill received substantial pharmaceutical funding, there was concern among the membership’s psychiatric patients and their families.
