Ciliary Extracellular Vesicles Are Distinct From The Cytosolic Extracellular Vesicles, Ashraf M. Mohieldin, Rajasekharreddy Pala, Richard Beuttler, James J. Moresco, John R. Yates Iii, Surya M. Nauli

Pharmacy Faculty Articles and Research

Extracellular vesicles (EVs) are cell‐derived membrane vesicles that are released into the extracellular space. EVs encapsulate key proteins and mediate intercellular signalling pathways. Recently, primary cilia have been shown to release EVs under fluid‐shear flow, but many proteins encapsulated in these vesicles have never been identified. Primary cilia are ubiquitous mechanosensory organelles that protrude from the apical surface of almost all human cells. Primary cilia also serve as compartments for signalling pathways, and their defects have been associated with a wide range of human genetic diseases called ciliopathies. To better understand the mechanism of ciliopathies, it is imperative to know …

Suppression Of Human Coronavirus 229e Infection In Lung Fibroblast Cells Via Rna Interference, Hamidreza Montazeri Aliabadi, Jennifer Totonchy, Parvin Mahdipoor, Keykavous Parang, Hasan Uludağ

Pharmacy Faculty Articles and Research

Despite extensive efforts to repurpose approved drugs, discover new small molecules, and develop vaccines, COVID-19 pandemic is still claiming victims around the world. The current arsenal of antiviral compounds did not perform well in the past viral infections (e.g., SARS), which casts a shadow of doubt for use against the new SARS-CoV-2. Vaccines should offer the ultimate protection; however, there is limited information about the longevity of the generated immunity and the protection against possible mutations. This study uses Human Coronavirus 229E as a model coronavirus to test the hypothesis that effective delivery of virus-specific siRNAs to infected cells will …

Save The Rich, Connor Harris

English Department: Research for Change - Wicked Problems in Our World

The problem of medication pricing and lobbying in the healthcare industry has caused millions of people within the United States to not be able to afford medications essential to their lives. Pharmaceutical companies are taking advantage of the need people have for certain drugs by setting the sale price far higher than it costs to produce. My suggested solution is to make lobbying illegal in the United States so that pharmaceutical companies would not have control over government officials who pass laws to help or hurt the issue of medication pricing. Illegalizing government lobbying will take away the incentive politicians …

Synthesis Of 1-(4-Ethoxy-3-Methoxybenzyl)-1,10-Phenanthrolin-1-Ium Bromide And Its Evaluation As Antiplasmodium Through Heme Polymerization Inhibitory Activity (Hpia) Assay, Dhina Fitriastuti, Viny Alfiyah, Mustofa Mustofa, Jumina Jumina, Muhammad Idham Darussalam Mardjan

Makara Journal of Science

This study describes the development of N-benzyl-1,10-phenantrolinium salt as an antiplasmodium agent. The salt, that is, 1-(4-ethoxy-3-methoxybenzyl)-1,10-phenanthrolin-1-ium bromide, was prepared using vanillin as the starting material in four simple synthetic steps. First, the alkylation of vanillin using diethyl sulfate produced 4-ethoxy-3-methoxybenzaldehyde in 79% yield. Second, the reduction of the protected vanillin by NaBH₄ through the grinding method allowed us to obtain 4-ethoxy-3-methoxybenzyl alcohol in 96% yield. Next, the bromination of the benzyl alcohol under solvent-free condition led to the formation of the corresponding benzyl bromide, which in turn underwent bimolecular nucleophilic substitution with 1,10-phenanthroline to produce the desired …

Synthesis Of N-Benzoyl-2-Hydroxybenzamides As Agents Utilized In Treatment Of Malaria, Brittany Krug, Gregory Naumeic

Arkansas Women in STEM Conference

Malaria is a disease that disproportionately affects several third world countries. It is a life-threatening illness that is transmitted by mosquitoes that act as vesicles for parasites. The parasites cause a febrile illness in those that are not immune. Children under five are most susceptible to the disease which can lead to multi-organ failure and death. The disease is preventable and curable, but according to the world health organization, countries disproportionately affected cannot afford these preventative care measures or have developed resistance to treatments. Therefore it would be advantageous to develop a new treatment for malaria that focuses on cost …

Evaluating Anesthetic Protocols For Non-Human Primate Functional Neuroimaging, Megha Verma

Electronic Thesis and Dissertation Repository

Functional magnetic resonance imaging (fMRI) is a non-invasive technique that can be used to measure a proxy of neural activity in vivo with high spatial specificity. One subject can be followed for a long period of time to assess changes in functional brain organization. However, fMRI is extremely sensitive to motion. The challenges of training non-human primates to reduce motion in an MRI scanner motivate the study of anesthesia which is commonly used to substitute for this training. In this thesis, I compare three different commonly used anesthetic protocols: isoflurane, propofol-fentanyl in combination, and fentanyl alone, to test which of …

This research examined the effect of biodegradable, polymeric, lignin-based nanoparticles (LNPs, 113.8±3.4, negatively charged) and zein nanoparticles (ZNP, 141.6±3.9, positively charged) on soybean plant health. The LNPs were synthesized from lignin, covalently linked to poly(lactic-co-glycolic) acid by emulsion evaporation. ZNPs were synthesized by nanoprecipitation. Soybeans grown hydroponically were treated with three concentrations (0.02, 0.2, and 2 mg/ml) of NPs at 28 days after germination. The effect of ZNPs and LNPs on plant health was determined through analysis of root and stem length, chlorophyll concentration, dry biomass of roots and stem, as well as carbon, nitrogen, and micronutrient absorption after 1, …

[(Wr)8Wkβa]-Doxorubicin Conjugate: A Delivery System To Overcome Multi-Drug Resistance Against Doxorubicin, Khalid Zoghebi, Hamidreza Montazeri Aliabadi, Rakesh Kumar Tiwari, Keykavous Parang

Pharmacy Faculty Articles and Research

Doxorubicin (Dox) is an anthracycline chemotherapeutic agent used to treat breast, leukemia, and lymphoma malignancies. However, cardiotoxicity and inherent acquired resistance are major drawbacks, limiting its clinical application. We have previously shown that cyclic peptide [WR]₉ containing alternate tryptophan (W) and arginine (R) residues acts as an efficient molecular transporter. An amphiphilic cyclic peptide containing a lysine (K) residue and alternative W and R was conjugated through a free side chain amino group with Dox via a glutarate linker to afford [(WR)₈WKβA]-Dox conjugate. Antiproliferative assays were performed in different cancer cell lines using the conjugate and the …

Liposomal Delivery Of Remdesivir For Localized And Targeted Treatment Of Covid-19, Anupama Melam

Liposomal delivery of Remdesivir for localized and targeted treatment of COVID-19

COVID-19 is a serious, and in many cases lethal, disease that is caused by infection of the upper respiratory tract by the novel betacoronavirus, SARS-Cov-2 virus. This disease has a very high mortality rate and has affected the world in a global pandemic. SARS-Cov-2 binds to the ACE2 receptor via the receptor-binding domain (RBD) in the S protein. After this, the virus fuses with the cell membrane by the formation of a six-helix bundle. Thus, the S protein plays a major role in ensuring that the virus attaches to …

Therapeutic Drug Monitoring Of Beta-Lactam Antibiotics In Critically Ill Patients With Sepsis, Melissa Thompson Bastin

Theses and Dissertations--Clinical and Translational Science

Sepsis is a devastating diagnosis affecting over 750,000 patients a year, accounting for approximately 10% of all hospital admissions, costs more than $50,000 per patient, and exceeds $17 billion annual spending. The mortality rate for sepsis remains unacceptably high: one out of every three patients diagnosed with sepsis dies. Sepsis physiology induces physiologic changes to drug pharmacokinetic (PK) parameters that alter the ability to achieve the goal pharmacodynamic (PD) target for beta-lactams of >4-fold unbound concentration above the minimum inhibitory concentration for 100% of the dosing interval (100% fT >4x MIC). Sepsis treatment such as volume resuscitation and vasopressor …

Investing Into Domestic Manufacturing Of Critical Medication And Vaccines For The Federal Government, Sharon Low

All Reports

While the federal government has made numerous public announcements regarding their stimulus plan and promises to increase the domestic capacity to produce personal protective equipment, vaccines, and medical equipment, a critical aspect that has been neglected is the serious and ongoing shortages of critical medication. The government has promised to provide 4.28 billion to expand testing and contact tracing capacities, 7.5 billion towards PPE, and 500 million to the provinces and territories for “critical health care system needs and support for mitigation effects.” While these efforts as part of Trudeau’s Safe Restart Agreement are a good place to begin reducing …

Association Of Electronic Prescription In Controlled Substances Used, Archana Suwal, Jemima Akinyi Okonjo

Theses, Dissertations and Capstones

Introduction: Controlled substances have been described as pharmaceuticals or illegal medicines that act primarily on the central nervous system and could cause physical and mental dependence, eventually leading to addiction. Prescription opioids were a significant contributor to the opioid epidemic, accounting for more than 70,000 opioid-related overdose deaths, including illicit and prescription opioids, between 2018 and 2019. The Electronic Prescriptions for Controlled Substances (EPCS) initiative recently aimed to reduce rates of prescription opioid addiction, abuse, diversion, and death. The system for controlled substances had become more widely used as providers and governments trying to combat the opioid problem. Because …

Vaccine Clinical Trials And Data Infrastructure, Ana Santos Rutschman

All Faculty Scholarship

We find ourselves at a momentous turn in the history of vaccines. The COVID-19 pandemic triggered a quasi-global vaccine race that not only compressed vaccine research and development (R&D) timelines, but also paved the way for the administration of a new type of vaccine technology – mRNA vaccines, which work in substantially different ways from the vaccines in use before the pandemic.

While the process of bringing emerging COVID-19 vaccines to market has taken place in an unusually short timeframe, it was largely predicated on the same scientific and regulatory processes that govern the development, approval and deployment of new …

Understanding The Impact Of Solvents In Oral Solid Dosage Formulation And Process Development, Matthew Kyle Defrese

Theses and Dissertations--Pharmacy

The successful delivery of chemical compounds for the purpose of therapeutic treatments and prophylactics is a substantial undertaking in modern drug development. Notably, the adoption of high throughput screening techniques has led to the proliferation of poorly water soluble and/or highly potent molecules which further complicate development activities. Spray dried amorphous solid dispersions are an increasingly important formulation strategy to overcome solubility issues while wet granulation approaches are the method of choice for the preparation of highly potent APIs in oral solid dosage forms.

A common connection between these critical techniques is their reliance on solvent-based processing that can often …
