Pharmacy Practice & Administration

Objective: To evaluate the reliability of a peer evaluation instrument in a longitudinal team-based learning setting.

Methods: Student pharmacists were instructed to evaluate the contributions of their peers. Evaluations were analyzed for the variance of the scores by identifying low, medium, and high scores. Agreement between performance ratings within each group of students was assessed via intra-class correlation coefficient (ICC).

Results: We found little variation in the standard deviation (SD) based on the score means among the high, medium, and low scores within each group. The lack of variation in SD of results between groups suggests that …

Biological Nanomotors With A Revolution, Linear, Or Rotation Motion Mechanism, Peixuan Guo, Hiroyuki Noji, Christopher M. Yengo, Zhengyi Zhao, Ian Grainge

Nanobiotechnology Center Faculty Publications

The ubiquitous biological nanomotors were classified into two categories in the past: linear and rotation motors. In 2013, a third type of biomotor, revolution without rotation (http://rnanano.osu.edu/movie.html), was discovered and found to be widespread among bacteria, eukaryotic viruses, and double-stranded DNA (dsDNA) bacteriophages. This review focuses on recent findings about various aspects of motors, including chirality, stoichiometry, channel size, entropy, conformational change, and energy usage rate, in a variety of well-studied motors, including F_oF₁ ATPase, helicases, viral dsDNA-packaging motors, bacterial chromosome translocases, myosin, kinesin, and dynein. In particular, dsDNA translocases are used to illustrate how …

Retigabine Holds Kv7 Channels Open And Stabilizes The Resting Potential, Aaron Corbin-Leftwich, Sayeed M. Mossadeq, Junghoon Ha, Iwona Ruchala, Audrey Han Ngoc Le, Carlos A. Villalba-Galea

School of Pharmacy Faculty Articles

The anticonvulsant Retigabine is a KV7 channel agonist used to treat hyperexcitability disorders in humans. Retigabine shifts the voltage dependence for activation of the heteromeric KV7.2/KV7.3 channel to more negative potentials, thus facilitating activation. Although the molecular mechanism underlying Retigabine's action remains unknown, previous studies have identified the pore region of KV7 channels as the drug's target. This suggested that the Retigabine-induced shift in voltage dependence likely derives from the stabilization of the pore domain in an open (conducting) conformation. Testing this idea, we show that the heteromeric KV7.2/KV7.3 channel has at least two open states, which we named O1 …

Unexpected Reaction Pathway For Butyrylcholinesterase-Catalyzed Inactivation Of "Hunger Hormone" Ghrelin, Jianzhuang Yao, Yaxia Yuan, Fang Zheng, Chang-Guo Zhan

Molecular Modeling and Biopharmaceutical Center Faculty Publications

Extensive computational modeling and simulations have been carried out, in the present study, to uncover the fundamental reaction pathway for butyrylcholinesterase (BChE)-catalyzed hydrolysis of ghrelin, demonstrating that the acylation process of BChE-catalyzed hydrolysis of ghrelin follows an unprecedented single-step reaction pathway and the single-step acylation process is rate-determining. The free energy barrier (18.8 kcal/mol) calculated for the rate-determining step is reasonably close to the experimentally-derived free energy barrier (~19.4 kcal/mol), suggesting that the obtained mechanistic insights are reasonable. The single-step reaction pathway for the acylation is remarkably different from the well-known two-step acylation reaction pathway for numerous ester hydrolysis reactions …

Incidence And Risk Factors Of Thromboembolism With Multiple Myeloma In The Presence Of Death As A Competing Risk: An Empirical Comparison Of Statistical Methodologies, Joshua D. Brown, Val R. Adams

Pharmacy Practice and Science Faculty Publications

Multiple myeloma (MM) has an inherent high risk of thromboembolic events associated with patient as well as disease- and treatment-related factors. Previous studies have assessed the association of MM-related thromboembolism using “traditional” Kaplan–Meier (KM) and/or Cox proportional hazard (PH) regression. In the presence of high incidence of death, as would be the case in cancer patients with advanced age, these statistical models will produce bias estimates. Instead, a competing risk framework should be used. This study assessed the baseline patient demographic and clinical characteristics associated with MM-related thromboembolism and compared the cumulative incidence and the measures of association obtained using …

Optimizing Guideline-Recommended Antibiotic Doses For Pediatric Infective Endocarditis, Chad A. Knoderer, Kristen R. Nichols, Emily N. Israel, Christopher A. Thomas

Scholarship and Professional Work – COPHS

The American Heart Association recently published an updated scientific statement on the management of infective endocarditis in childhood. The recommendations included for vancomycin, aminoglycoside, and β-lactam dosing and monitoring are based primarily on expert opinion and do not consider available evidence for dose optimization based on pharmacokinetic and pharmacodynamic principles in pediatric patients. This is concerning because even when clinically necessary, some practitioners may be hesitant to deviate from guideline-recommended doses. In this perspective, we highlight potential areas for improvement in the statement-recommended doses and summarize evidence supporting antibiotic dosing optimization. The addition of a pediatric clinical pharmacist with expertise …

Treatment Modalities And Antimicrobial Stewardship Initiatives In The Management Of Intra-Abdominal Infections, Charles Hoffmann, Matthew Zak, Lisa M. Avery, Jack Brown

Pharmacy Faculty/Staff Publications

Antimicrobial stewardship programs (ASPs) focus on improving the utilization of broad spectrum antibiotics to decrease the incidence of multidrug-resistant Gram positive and Gram negative pathogens. Hospital admission for both medical and surgical intra-abdominal infections (IAIs) commonly results in the empiric use of broad spectrum antibiotics such as fluoroquinolones, beta-lactam beta-lactamase inhibitors, and carbapenems that can select for resistant organisms. This review will discuss the management of uncomplicated and complicated IAIs as well as highlight stewardship initiatives focusing on the proper use of broad spectrum antibiotics.

Development And Validation Of A Sensitive Uplc-Ms/Ms Method For The Quantitation Of [13c]Sucrose In Rat Plasma, Blood, And Brain: Its Application To The Measurement Of Blood-Brain Barrier Permeability, Mohammad K. Miah, Ulrich Bickel, Reza Mehvar

Pharmacy Faculty Articles and Research

Accurate and reproducible measurement of blood-brain barrier (BBB) integrity is critical in the assessment of the pathophysiology of the central nervous system disorders and in monitoring therapeutic effects. The widely-used low molecular weight marker [14C]sucrose is non-specific in the absence of chromatographic separation. The purpose of this study was to develop and validate a sensitive and reproducible LC-MS/MS method for the analysis of stable isotopemodified [13C12]sucrose in brain, plasma, and blood to determine BBB permeability to sucrose. After addition of internal standard (IS, [13C6]sucrose), the marker and IS were recovered from diluted rat blood, plasma, and brain homogenate by protein …

Selective Binding Of Airapl Tandem Uims To Lys48-Linked Tri-Ubiquitin Chains, Simin Rahighi, Ilauna Braunstein, Nicola Ternette, Benedikt Kessler, Masato Kawasaki, Ryuichi Kato, Tsutomu Matsui, Ariel Stanhill, Soichi Wakatsuki

Pharmacy Faculty Articles and Research

Lys48-linked ubiquitin chains act as the main targeting signals for protein degradation by the proteasome. Here we report selective binding of AIRAPL, a protein that associates with the proteasome upon exposure to arsenite, to Lys48-linked tri-ubiquitin chains. AIRAPL comprises two ubiquitin-interacting motifs in tandem (tUIMs) that are linked through a flexible inter-UIM region. In the complex crystal structure UIM1 binds the proximal ubiquitin, whereas UIM2 (the double-sided UIM) binds non-symmetrically to the middle and distal ubiquitin moieties on either side of the helix. Specificity of AIRAPL for Lys48-linked ubiquitin chains is determined by UIM2, and the flexible inter-UIM linker increases …

Targeting An Essential Gtpase Obg For The Development Of Broad-Spectrum Antibiotics, Josephine A. Bonventre, Ryszard A. Zielke, Konstantin V. Korotkov, Aleksandra E. Sikora

Molecular and Cellular Biochemistry Faculty Publications

A promising new drug target for the development of novel broad-spectrum antibiotics is the highly conserved small GTPase Obg (YhbZ, CgtA), a protein essential for the survival of all bacteria including Neisseria gonorrhoeae (GC). GC is the agent of gonorrhea, a prevalent sexually transmitted disease resulting in serious consequences on reproductive and neonatal health. A preventive anti-gonorrhea vaccine does not exist, and options for effective antibiotic treatments are increasingly limited. To address the dire need for alternative antimicrobial strategies, we have designed and optimized a 384-well GTPase assay to identify inhibitors of Obg using as a model Obg protein from …

Effectiveness Of Pharmacist-Led Amiodarone Monitoring Services On Improving Adherence To Amiodarone Monitoring Recommendations: A Systematic Review, Dave L. Dixon, Steven P. Dunn, Michael S. Kelly, Timothy R. Mcllarky, Roy E. Brown

Pharmacy Faculty Articles and Research

Amiodarone remains the mostly frequently used antiarrhythmic in clinical practice and is most often used to maintain normal sinus rhythm in patients with atrial fibrillation who have failed a rate control strategy. Amiodarone has superior efficacy over other antiarrhythmics, a lower risk of torsade de pointes, and a better cardiovascular safety profile in patients with structural heart disease. However, amiodarone is associated with notable noncardiac toxicities affecting the thyroid, lungs, eyes, liver, and central nervous system. Since 2000, clinicians have been advised to follow amiodarone monitoring guidelines provided by the Heart Rhythm Society. Adherence to these recommendations in clinical practice, …

Loop Dynamics Of Thymidine Diphosphate-Rhamnose 3'-O-Methyltransferase (Cals11), An Enzyme In Calicheamicin Biosynthesis, Lu Han, Shanteri Singh, Jon S. Thorson, George N. Phillips Jr.

Center for Pharmaceutical Research and Innovation Faculty Publications

Structure analysis and ensemble refinement of the apo-structure of thymidine diphosphate (TDP)-rhamnose 3'-O-methyltransferase reveal a gate for substrate entry and product release. TDP-rhamnose 3'-O-methyltransferase (CalS11) catalyses a 3'-O-methylation of TDP-rhamnose, an intermediate in the biosynthesis of enediyne antitumor antibiotic calicheamicin. CalS11 operates at the sugar nucleotide stage prior to glycosylation step. Here, we present the crystal structure of the apo form of CalS11 at 1.89 Å resolution. We propose that the L2 loop functions as a gate facilitating and/or providing specificity for substrate entry or promoting product release. Ensemble refinement analysis slightly improves the …

Utilization And Costs Of Compounded Medications For Commercially Insured Patients, 2012 – 2013, Timothy Mcpherson, Patrick Fontane Phd, Express Scripts Holding Company

SIUE Faculty Research, Scholarship, and Creative Activity

Background: Although compounding has a long-standing tradition in clinical practice, insurers and pharmacy benefit managers have instituted policies to decrease claims for compounded medications, citing questions about their safety, efficacy, high costs, and lack of Food and Drug Administration (FDA) approval. There are no reliable published data on the extent of compounding by community pharmacists nor the fraction of patients who use compounded medications. Prior research suggests that compounded medications represent a relatively small proportion of prescription medications, but these surveys were limited by small sample sizes, subjective data collection methods, and low response rates.

Objective: To determine the number …

Computational And Experimental Determination Of The Hydrodynamics In A Stirred Unbaffled Vessel Provided With Angle-Mounted Axial Impellers, Ji Ma

Theses

In most industrial applications, stirred tanks and reactors are typically provided with baffles to improve their mixing characteristics. However, in a number of pharmaceutical production facilities unbaffled vessels are commonly used. The absence of baffles is preferred in such cases because it reduces the potential for contamination and makes cleaning the vessel between batches easier. However, the lack of baffles also has a negative impact on the system’s hydrodynamics since it often results in poor mixing of the batch, especially if the impeller is centrally placed, since the liquid in such a system is subject to a strong tangential flow, …

A Comprehensive Behavioral Test Battery To Assess Learning And Memory In 129s6/Tg2576 Mice, Andrea Wolf, Björn Bauer, Erin L. Abner, Tal Ashkenazy-Frolinger, Anika M. S. Hartz

Pharmaceutical Sciences Faculty Publications

Transgenic Tg2576 mice overexpressing human amyloid precursor protein (hAPP) are a widely used Alzheimer’s disease (AD) mouse model to evaluate treatment effects on amyloid beta (Aβ) pathology and cognition. Tg2576 mice on a B6;SJL background strain carry a recessive rd1 mutation that leads to early retinal degeneration and visual impairment in homozygous carriers. This can impair performance in behavioral tests that rely on visual cues, and thus, affect study results. Therefore, B6;SJL/Tg2576 mice were systematically backcrossed with 129S6/SvEvTac mice resulting in 129S6/Tg2576 mice that lack the rd1 mutation. 129S6/Tg2576 mice do not develop retinal degeneration but still show Aβ accumulation …
