In Silico Molecular Docking Analysis To Predict The Role Of Metal Ions In The Function Of Drug Targeted Proteins, S. M. A. Shahid, Qazi M. S. Jamal, J. M. Arif, Fahad M. Al-Khodairy, Anupam Dhasmana, Mohtashim Lohani

School of Medicine Publications

Metal ions are required for many critical functions in living systems. Scarcity of some metal ions can lead to disease. A characteristic of metals is that they easily lose electrons from the familiar elemental or metallic state to form positively charged ions which tend to be soluble in biological fluids. Role of zinc, calcium and copper ions in the catalytic mechanism of drug targeted proteins such as Farnesyltransferase, Neuraminidase and Thioredoxin are analyzed using molecular docking, respectively. The docking results show that inhibitors have low Binding, docking and internal energies with proteins in the presence of Zn, Ca and Cu …

Higher Hepatic Mir-29 Expression In Undernourished Male Rats During The Postnatal Period Targets The Long-Term Repression Of Insulin-Like Growth Factor 1, Gurjeev Sohi, Andrew Revesz, Julie Ramkumar, Daniel B. Hardy

Physiology and Pharmacology Publications

A nutritional mismatch in postnatal life of low birth weight offspring increases the risk of developing the metabolic syndrome. Moreover, this is associated with decreased hepatic insulin-like growth factor 1 (Igf1) expression, leading to impaired growth and metabolism. Previously we have demonstrated that the timing of nutritional restoration in perinatal life can differentially programhepatic gene expression. While micro RNAs also play an important role in silencing gene expression, to date, the impact of a nutritional mismatch in neonatal life on their long-term expression has not been evaluated. Given the complementarity of miR-29 to the 3i-UTR of Igf1, we examined how …

Flucytosine Pharmacokinetics In A Critically Ill Patient Receiving Continuous Renal Replacement Therapy, Megan E. Kunka, Elizabeth A. Cady, Heejung C. Woo, Melissa L. Thompson Bastin

Pharmacy Practice and Science Faculty Publications

Purpose. A case report evaluating flucytosine dosing in a critically ill patient receiving continuous renal replacement therapy. Summary. This case report outlines an 81-year-old male who was receiving continuous venovenous hemofiltration (CVVH) for acute renal failure and was being treated with flucytosine for the treatment of disseminated Cryptococcus neoformans infection. Due to patient specific factors, flucytosine was empirically dose adjusted approximately 50% lower than intermittent hemodialysis (iHD) recommendations and approximately 33% lower than CRRT recommendations. Peak and trough levels were obtained, which were supratherapeutic, and pharmacokinetic parameters were calculated. The patient experienced thrombocytopenia, likely due to elevated flucytosine …

Cationic Cell-Penetrating Peptides Are Potent Furin Inhibitors, Bruno Ramos-Molina, Adam N. Lick, Amir Nasrolahi Shirazi, Donghoon Oh, Rakesh Tiwari, Naglaa Salem El-Sayed, Keykavous Parang, Iris Lindberg

Pharmacy Faculty Articles and Research

Cationic cell-penetrating peptides have been widely used to enhance the intracellular delivery of various types of cargoes, such as drugs and proteins. These reagents are chemically similar to the multi-basic peptides that are known to be potent proprotein convertase inhibitors. Here, we report that both HIV-1 TAT47-57 peptide and the Chariot reagent are micromolar inhibitors of furin activity in vitro. In agreement, HIV-1 TAT47-57 reduced HT1080 cell migration, thought to be mediated by proprotein convertases, by 25%. In addition, cyclic polyarginine peptides containing hydrophobic moieties which have been previously used as transfection reagents also exhibited potent furin inhibition in vitro …

Systemic siRNA administration to target and treat glioblastoma, one of the most deadly cancers, requires robust and efficient delivery platform without immunogenicity. Here we report newly emerged multivalent naked RNA nanoparticle (RNP) based on pRNA 3-way-junction (3WJ) from bacteriophage phi29 to target glioblastoma cells with folate (FA) ligand and deliver siRNA for gene silencing. Systemically injected FA-pRNA-3WJ RNPs successfully targeted and delivered siRNA into brain tumor cells in mice, and efficiently reduced luciferase reporter gene expression (4-fold lower than control). The FA-pRNA-3WJ RNP also can target human patient-derived glioblastoma stem cells, thought to be responsible for tumor initiation and deadly …

Review Of Edison Bicudo, Pharmaceutical Research, Democracy And Conspiracy: International Clinical Trials In Local Medical Institutions, Roberto Abadie

Department of Sociology: Faculty Publications

The pharmaceutical industry is—along with the financial and weapons industries—one of the most globalized and profitable business domains. But they wouldn’t make any profits if they weren’t able to recruit research subjects to test an increasing number of drugs. This global trial economy creates its own assemblages of clinical trials, often run by hired contract research organizations (CROs), who fight among each other in a rat-race competition, promising quick and effective trials; at the same time, enterprising countries, hospitals, and doctors jump on the drug trial economy bandwagon by promising quick, endless access to a large pool of research subjects, …

Irisin Evokes Bradycardia By Activating Cardiac-Projecting Neurons Of Nucleus Ambiguus., Eugen Brailoiu, Elena Deliu, Romeo A Sporici, Gabriela Cristina Brailoiu

College of Pharmacy Faculty Papers

Irisin is a newly identified hormone induced in muscle and adipose tissues by physical activity. This protein and its encoding gene have been identified in the brain; in addition, the precursor for irisin, FNDC5, can cross the blood-brain barrier. The fact that irisin is secreted during exercise together with the lower resting heart rate in athletes prompted us to investigate the effect of irisin on cardiac-projecting vagal neurons of nucleus ambiguus, a key regulatory site of heart rate. In vitro experiments in cultured nucleus ambiguus neurons indicate that irisin activates these neurons, inducing an increase in cytosolic Ca(2+) concentration and …

Awareness And Utilization Of The Ohio Automated Rx Reporting System By Physician Assistants, Julia Cathleen Rose

All Theses And Dissertations

Chronic pain has become a public health epidemic. As pain complaints increase, so does the potential for drug abuse/misuse. Prescription drug monitoring programs (PDMPs) are active in 49 of the 50 states to assist providers in recognizing drug abuse/misuse. There is no clear standardization of who utilizes the PDMP and how. Little is still known about the ways PDMP results are incorporated into clinical decision making, what barriers exist, and how providers may or may not alter their prescribing plans based on the results. Laws surrounding prescribing practices and use of the Ohio Automated Rx Reporting System (OARRS) are constantly …

Mala Lā’Au Lapa’Au: Preserving The Hawaiian ‘Āina And Mo’Omehue, Sandra Fogg

Senior Honors Projects

The study of medicinal plants in the western world tends to focus on the isolation and elucidation of natural products that have bioactive characteristics and potential for pharmaceutical formulation. However, the utilization of medicinal plants in cultures that still practice ancient medicine, such as Hawai’i and other Pacific Island nations, involves the use of whole plant parts in conjunction with spiritual rituals to heal illnesses and ailments. In order to gather a different perspective of the use of plants in medicine, a diverse investigation of “Lā’au Lapa’au,” or the Hawaiian art of healing through the use of plants and spiritual …

Experimental Determination Of Solids Suspension With Angled Impeller In A Pharmaceutical Mixing Vessel, Yingxi Tang

Theses

Angled-mounted impellers are commonly used in a number of pharmaceutical industry applications, from laboratory reactors to full-scale tanks. In these systems, the impeller is not centrally and vertically mounted, as in most stirred vessels, but it enters the vessel, and is therefore immersed in the fluid, at an angle from the vertical. This arrangement provides some baffling effects that would not otherwise exist if the impeller was centrally mounted.

One common requirement for such systems is that they are capable of suspending small solids dispersed in the liquid. Therefore, it is critical to know the value of the minimum agitation …

Effect Of Impeller Submergence On Power Dissipation And Solids Suspension In Mixing Systems Equipped With Pitch-Blade Turbines, Yufeng Song

Theses

Mixing and dispersion of solids in a liquid is a process frequently encountered in the pharmaceutical industry and often conducted in cylindrical baffled tanks stirred by mechanical impellers. In operations where the liquid level is decreased (as often which emptying the tank) the process must be stopped when the solids are no longer suspended. In this work, the minimum agitation to suspend solids (Njs) when the liquid level was lowered, and the impeller submergence S_b changed as a result were determined for the case of a six-blade, pitch-blade turbine (6-PBT) impeller. The power consumed by the impeller …

Experimental Determination Of The Agitation Requirements For Solids Suspension In Dissolution Systems Using A Mini Paddle Apparatus, Yang Song

Theses

Dissolution testing is a critical step in quality control of manufactured final products in the pharmaceutical industry. The United State Pharmacopeia (USP) Dissolution Testing Apparatus 2 (paddle) is the most widely used dissolution test devices in the pharmaceutical industry to formulate solid drug dosage forms and to develop quality control specifications for its manufacturing process.

Mini vessels and mini paddle dissolution testing systems are smaller versions of the USP 2 Apparatus. The concept of the mini paddle apparatus is similar to that of the USP 2 setup but it is scaled down about to 1/5 of the volume and 40% …

Identification Of Novel Genes That Regulate Androgen Receptor Signaling And Growth Of Androgen-Deprived Prostate Cancer Cells, Elina Levina, Hao Ji, Mengqiang Chen, Mirza Baig, David Oliver, Patrice Ohouo, Chang-Uk Lim, Garry Schools, Steven Carmack, Ye Ding, Eugenia Broude, Igor Roninson, Ralph Buttyan, Michael Shtutman

Faculty Publications

Prostate cancer progression to castration refractory disease is associated with anomalous transcriptional activity of the androgen receptor (AR) in an androgen-depleted milieu. To identify novel gene products whose downregulation transactivates AR in prostate cancer cells, we performed a screen of enzymatically-generated shRNA lenti-libraries selecting for transduced LNCaP cells with elevated expression of a fluorescent reporter gene under the control of an AR-responsive promoter. The shRNAs present in selected populations were analyzed using high-throughput sequencing to identify target genes. Highly enriched gene targets were then validated with siRNAs against selected genes, testing first for increased expression of luciferase from an AR-responsive …

Implementation Of A Student Development Workshop Series To Supplement A Traditional Curriculum, Melinda E. Lull, Jennifer Mathews

Pharmacy Faculty/Staff Publications

Preparing students to be successful in the classroom and as professionals requires more than didactic education. Academic programs primarily address the academic needs of students based on curricular and assessment goals but often fail to fully prepare students to successfully face the challenges they experience in school and after graduation. To truly prepare students, teachers must address their needs in domains outside the classroom. This session explores student development programs aimed at improving students’ academic, personal, and future professional success as a supplement to the traditional didactic education.

Learning goals:

Expanding The Role Of Peer Tutors Through The Use Of Online Quizzes, Melinda E. Lull, Jennifer Mathews

Pharmacy Faculty/Staff Publications

Peer tutors are commonly used in higher education as a way to provide additional resources for student learning. Self‐testing, a type of formative assessment tool, provides students with a study tool that can help identify areas of weakness that require focus. Despite their usefulness, this type of additional learning resource can often be time consuming for faculty members, limiting its successful use across multiple courses. The use of peer tutors has been investigated and shown to provide advantages to both students utilizing tutoring services and tutors alike. Educating peer tutors to be involved in the academic process by preparing study …

The Biosynthesis Of Capuramycin-Type Antibiotics: Identification Of The A-102395 Biosynthetic Gene Cluster, Mechanism Of Self-Resistence, And Formation Of Uridine-5'-Carboxamide, Wenlong Cai, Anwesha Goswami, Zhaoyong Yang, Xiaodong Liu, Keith D. Green, Sandra Barnard-Britson, Satoshi Baba, Masanori Funabashi, Koichi Nonaka, Manjula Sunkara, Andrew J. Morris, Anatol P. Spork, Christian Ducho, Sylvie Garneau-Tsodikova, Jon S. Thorson, Steven Van Lanen

Pharmaceutical Sciences Faculty Publications

A-500359s, A-503083s, and A-102395 are capuramycin-type nucleoside antibiotics that were discovered using a screen to identify inhibitors of bacterial translocase I, an essential enzyme in peptidoglycan cell wall biosynthesis. Like the parent capuramycin, A-500359s and A-503083s consist of three structural components: a uridine-5'-carboxamide (CarU), a rare unsaturated hexuronic acid, and an aminocaprolactam, the last of which is substituted by an unusual arylamine-containing polyamide in A-102395. The biosynthetic gene clusters for A-500359s and A-503083s have been reported, and two genes encoding a putative non-heme Fe(II)-dependent α-ketoglutarate:UMP dioxygenase and an l-Thr:uridine-5'-aldehyde transaldolase were uncovered, suggesting that C-C bond formation during assembly of …

Haemophilus Influenzae Responds To Glucocorticoids Used In Asthma Therapy By Modulation Of Biofilm Formation And Antibiotic Resistance, Chris S. Earl, Tee Wooi Keong, Shi-Qi An, Sarah Murdoch, Yvonne Mccarthy, Junkal Garmendia, Joseph Ward, J Maxwell Dow, Liang Yang, George A. O'Toole, Robert P. Ryan

Dartmouth Scholarship

Glucocorticosteroids are used as a main treatment to reduce airway inflammation in people with asthma who suffer from neutrophilic airway inflammation, a condition frequently associ- ated with Haemophilus influenzae colonization. Here we show that glucocorticosteroids have a direct influence on the behavior of H. influenzae that may account for associated difficulties with therapy. Using a mouse model of infection, we show that cortico- steroid treatment promotes H. influenzae persistence. Transcrip- tomic analysis of bacteria either isolated from infected mouse airway or grown in laboratory medium identified a number of genes encoding regulatory factors whose expression responded to the presence of …

Analyzation Of Metabolic Reprogramming In Drug-Resistant Mcf-7 Cells, Derick Han, Ho Leung, Andrew Vo

Student Scholar Symposium Abstracts and Posters

The Warburg effect states that cancer cells mainly receive their energy from anaerobic glycolysis. Thus, mitochondria play a different role in the metabolism of cancer cells as opposed to normal, healthy cells. In chemotherapy, there is always a chance of the cancer regressing. Making drug-resistant cancer cells to analyze their metabolism may change how cancer is treated. This study aimed to create drug-resistant MCF-7 cell lines with doxorubicin in order to determine the metabolic changes that have occurred in the process of becoming resistant to drug treatments.

Clinical Applications Of A Combination Chemotherapy Using 8-Chloro Camp And 8-Chloro Adenosine, Erik Munoz, Andrea Saich, Andrew Cox, Yu-An Peter Chang

Student Scholar Symposium Abstracts and Posters

Dr. Cho-Chung from the NIH first thought to use halogenated cAMP derivatives as competitive inhibitors of cAMP to slow down cancer cell mitosis. While the iodine and bromine substituted versions showed very little therapeutic actions, 8-Chloro cAMP has been shown to have strong anti-cancer effects. This has been shown in the phase II clinical trials this drug has undergone. However, these trials have had issues with solubility and toxicity. The drug is similar to vitamin C and is excreted quickly. Scientists tried to overcome this by using a peristaltic pump to give patients a continuous dosage, but this proved too …

Programming Macrophage Inflammation Resolution: The Role Of Omega-3 Polyunsaturated Fatty Acids, Boris Krasnov, Mathew Lombardozzi, Maria Caraballo, Ramil Sapinoro

Pharmacy Faculty/Staff Publications

It was previously thought that resolution of inflammation was a passive process, but recent emerging research has identified that resolution is an active process and that dual acting lipid mediators derived from essential omega-3 polyunsaturated fatty acids (PUFAs) have both anti-inflammatory (reducing neutrophil access to the inflamed tissue) and pro-resolving (removal of apoptotic cells by macrophages in the inflamed site) actions. The objective of our study was to determine the role of omega-3 PUFAs in programming phenotypic changes in treated macrophages. The polarization of macrophages during inflammatory responses to functionally distinct phenotypes may play a role in both inflammation and …

Critical Analysis Of The Confounding Of Clinical Trials, Eleanor L. Jordan

Senior Honors Projects, 2010-2019

To provide a comprehensive overview of issues confounding clinical trials, Chapter 2 will discuss the parties involved in the research and development of medications and detail the individual responsibilities of each. However, the ambition of these individual entities often produces a conflict of interest especially when profits are involved [9]. Organizations and individuals such as insurance corporations, pharmaceutical companies (sponsors), pharmacy benefit managers, investigators (doctors/medical professionals) and most importantly patients, are all involved in carrying out clinical research and have definitive responsibilities they are required to follow for unbiased results. However, many rules are overlooked and biases go unrecorded causing …
