Targeting Neuronal Nitric Oxide Synthase (Nnos) For Melanoma Treatment, Shirley Tong

Pharmaceutical Sciences (PhD) Dissertations

Human cutaneous melanoma is the most aggressive form of skin cancer and the incidence rates have continued to increase over the years. Neuronal nitric oxide synthase (nNOS) produces nitric oxide (NO) has been found to be overexpressed in human melanoma and the expression of nNOS is induced by interferon-gamma (IFN-γ). In our studies, nNOS has been implicated in IFN-γ-stimulated melanoma progression and the inhibition of nNOS using novel inhibitors effectively inhibited IFN-γ-stimulated tumor growth in a xenograft mouse model. Programmed death-ligand 1 (PD-L1) is overexpressed in melanoma and plays an important role in suppressing the immune system ^12-14. Our …

Multimodal Approach To Chronic Pain Management And Prevention Of Opioid Use Disorder, Hannah Elston

The Eleanor Mann School of Nursing Undergraduate Honors Theses

Background. Chronic pain (CP) is a major public health problem that affects one-third of the population and can interfere with the activities of daily life and cause decreased quality of life. Patients with CP have been increasingly prescribed opioids, contributing to the rise in the opioid epidemic. Due to the long-term nature of CP, the use of opioids as the sole treatment for CP can cause tolerance and increased dosages overtime which can lead to addiction and potentially overdose. Therefore, CP treatment should include multimodal approaches to treatment to prevent opioid misuse, opioid use disorder (OUD), and overdose. Multimodal treatments …

The Effects Of Paclitaxel On Cellular Migration And The Cytoskeleton, Ashley Salguero-Gonzalez

Thinking Matters Symposium

In a clinical setting, some patients are exposed to an anti-cancer chemotherapy agent, paclitaxel. Cancerous cells undergo rapid, continuous cell division without control. Chemotherapy treatments try to slow and stop the uncontrollable cell division cycles and eliminate cancerous cells in the process. Paclitaxel serves as a treatment for some types of cancers, including lung, melanoma, bladder, and esophageal. Because it targets the cytoskeleton, paclitaxel can also influence cell migration. This project utilizes a cellular migration assay and an immunohistochemistry assay to analyze the effects of paclitaxel on the movement of cells and on the cytoskeleton of neuroglia rat cells with …

Despite the benefits of red blood cell (RBC) transfusion therapy, it can render patients vulnerable to iron overload. The excess iron deposits in various body tissues cause severe complications and organ damage such as cardiotoxicity and mold infections. Clostridioides difficile infection (CDI) is the most common cause of nosocomial diarrhea among cancer patients and is associated with significant morbidity and mortality. Our study aims to determine the role of iron overload and the effects of iron chelators on CDI. Our results demonstrated that iron (Fe³⁺) stimulated the growth of C. difficile with increased colony formation units (CFU) in …

Oleyl Conjugated Histidine-Arginine Cell-Penetrating Peptides As Promising Agents For Sirna Delivery, Muhammad Imran Sajid, Dindyal Mandal, Naglaa Salem El-Sayed, Sandeep Lohan, Jonathan Moreno, Rakesh Kumar Tiwari

Pharmacy Faculty Articles and Research

Recent approvals of siRNA-based products motivated the scientific community to explore siRNA as a treatment option for several intractable ailments, especially cancer. The success of approved siRNA therapy requires a suitable and safer drug delivery agent. Herein, we report a series of oleyl conjugated histidine–arginine peptides as a promising nonviral siRNA delivery tool. The conjugated peptides were found to bind with the siRNA at N/P ratio ≥ 2 and demonstrated complete protection for the siRNA from early enzymatic degradation at N/P ratio ≥ 20. Oleyl-conjugated peptide -siRNA complexes were found to be noncytotoxic in breast cancer cells (MCF-7 and MDA-MB-231) …

Acetaminophen, A Therapeutic Or An Extremely Toxic Remedy – A Review, Genica Caragea, Oana Avram, Andreea Pauna, Andreea Cristina Costea, Miruna Tudosie

Journal of Mind and Medical Sciences

When a new coronavirus appeared in the late 2019, identified as the cause of several cases of pneumonia in Wuhan, Paracetamol was initially reported to be the preferable antipyretic medication, choice which was detrimental to the use of other drugs. People have resorted to buying large stocks of Paracetamol and some have used it in large doses, regardless of the consequences. However, the Paracetamol (Acetaminophen) overdose remains the leading cause of death or transplantation due to acute liver failure in many parts of the world. This review aims at presenting the pharmacokinetics, the clinical signs, and the risk factors for …

Prenatal Drug Exposure And Its Effects On Fetal Development: Clinical And Health Education Implications, Johanna Marie Olo Tapangan

Senior Honors Theses

Prenatal drug exposure is a common clinical phenomenon in pregnancy cases. Pregnancy is a fragile period of time for both the mother and the fetus. Therefore, strict drug regulation is important to ensure the safety and wellbeing of the developing fetus. Certain drugs, once thought to be safe, have been found to have detrimental effects on the normal development of functioning organ systems in the fetus. Current research has identified drugs that when taken during pregnancy can result in the onset of fetal physical abnormalities, impaired brain development, and disrupted organogenesis and organ function. Thalidomide, losartan, opioids, alcohol, and caffeine …

Evaluation Of Protective Efficacy Of Viral Vector Based Swine Influenza Vaccine And A Method For B Cell Culture For Monoclonal Antibody Generation, Sushmita Kumari

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Influenza A virus of the swine (IAV-S) is an economically important swine pathogen that has the potential to spread to humans, thus posing an ongoing public health concern due to its zoonotic potential. Hemagglutinin (HA), the most abundant viral envelope protein, is known to be the key protective antigen. Anti-HA antibodies alone, have been shown to prevent IAV infection. In this study we evaluated the feasibility of a recombinant tri segmented Pichinde virus (PICV) as a viral vector to deliver IAV-S hemagglutinin antigen in pigs. Four groups of weaned pigs (T01-04) were immunized twice with PBS, rPICV-GFP as a vector …

Targeting Protein Degradation To Uncover Novel Oncoprotein Drivers Of Acute Leukemia, Fatemeh Keramatnia

Theses and Dissertations (ETD)

Acute Lymphoblastic Leukemia (ALL), the most common childhood cancer and the second most common acute leukemia in adults, arises from clonal expansion of undifferentiated lymphoid precursor cells in bone marrow. Despite the extensive knowledge on its cytogenetic and molecular biology, ALL treatment remains highly challenging especially after relapse. Conventional chemotherapy has shown significant improvement in overall survival rates of pediatric patients up to 90%, however, treatment failure due to ALL relapse occurs in 15-20% of the cases. On the other hand, adults and elderly patients with ALL are considered difficult to treat populations with the 5-year overall survival of 30–40%. …

A Proposed Treatment Of Mixed Connective Tissue Disease By Competitive Inhibition Of Autoantibodies, Thomas Russell

Senior Honors Theses

Mixed Connective Tissue Disease is an autoimmune disease characterized by Raynaud’s phenomenon and arthritis among other symptoms. It is primarily caused by antibodies that target the U1-RNP 70K peptide. The treatment proposed in this paper uses competitive inhibition to prevent the binding of the anti-U1-RNP 70K antibodies with the U1-RNP 70K peptide. A method for testing the designed treatment in silico is proposed using AutoDock Vina docking software.
