Role Of Limonene In An Experimental Model Of Rotenone Induced Parkinson’S Disease, Lujain Mohamad Bader Eddin

Theses

Parkinson's disease (PD) is one of the prevalent neurodegenerative diseases in elderly population. The symptoms of PD often begin with motor and cognitive impairment that are attributed to the dopaminergic neurons degeneration. Rotenone (ROT) is a naturally derived pesticide that is used in agriculture to control pests. It is a neurotoxin well-established for use in resembling PD symptoms in research. Limonene (LMN) is a plant derived monoterpene extracted from citrus peel with a wide range of therapeutic effects. Due to the shortage in available therapeutic agents that can cure or halt the progressive degeneration of PD, the main aim of …

Decreasing Unintentional Pregnancies For Tennesseans, Paula M. Todd

Electronic Theses and Dissertations

In 2018, 49% of all pregnancies in the United States were unintended, with women with a lower- income status being five times more likely to experience an unplanned pregnancy. Tennessee has a high rate of unintended pregnancies, particularly among the uninsured, low-income, and rural teen populations; some 22% of these unintended pregnancies end in abortion. Oral or transdermal contraceptives that are affordable and accessible for women of childbearing age can reduce unintentional pregnancies. The addressed gap in clinical practice was that contraceptives are not currently available over the counter in Tennessee pharmacies without a prescription, which necessitates a costly medical …

Point Substitutions In G Protein-Coupled Receptors, Jessica Brown

Undergraduate Student Research Internships Conference

G protein-coupled receptors (GPCRs) are proteins that are important in physiological regulatory processes within the body, and for this reason are important drug targets. When bound to an agonist, such as neurotransmitters or hormones, the receptor adopts an active state to allow these biochemical pathways to occur. However, mutations can arise within the receptor that affect its ability to bind its agonist. This natural variation found within the genome can make it difficult to design pharmaceuticals to target the receptors.

To see the effects of these point substitutions on agonist-induced receptor activation, mutations were made within a negative allosteric site …

Effect Of Carbon Monoxide Releasing Molecule 3 (Corm - 3) On Platelet Adhesion To Human Brain Microvascular Endothelial Cells, Najat S. El-Farra

Undergraduate Student Research Internships Conference

Sepsis is characterized by the widespread inflammation of the body. Systemic inflammation activates and recruits inflammatory cells (e.g., leukocytes) and platelets to the affected organs.

During these inflammatory conditions, human brain microvascular endothelial cells (hBMEC) and platelets both upregulate adhesive molecules rendering platelets to adhere to hBMEC.

Although carbon monoxide is thought of as a toxic molecule to many, previous work shows its anti-inflammatory properties. Evidence has shown carbon monoxide-releasing molecules (e.g., CORM-3; that release small, non-toxic amounts of CO) can combat the effects of severe inflammation in several in vivo animal model.

In this current study, we are looking …

Proof Of Concept: The Use Of Renal Biomarkers In Critically Ill Pediatric Patients For Therapeutic Drug Monitoring, Christopher Lee Shaffer

Theses & Dissertations

Acute kidney injury (AKI) is a serious and common complication in critically ill pediatric patients. The incidence of pediatric AKI continues to increase, especially in patients who undergo surgical correction of congenital heart defects. Serum creatinine and urine output are the most commonly used tools to assess renal function, with international guidelines standardizing AKI-definitions based upon these parameters. However, changes in serum creatinine can occur 24 hours or later after a renal insult event, delaying the diagnosis and potential interventions to reverse injury. It is critical to identify endogenous renal biomarkers within the pediatric population that are both timely and …

Decreased Kidney Mitochondrial Content And Pgc-1Α Following Repeated Low-Dose Cisplatin-Induced Kidney Injury., Andrew Joseph Orwick

Electronic Theses and Dissertations

Cisplatin is highly effective and one of the most commonly used chemotherapeutic agents in the treatment of a number of different solid organ tumors. Unfortunately, the dose-limiting nephrotoxicity occurs in up to 30% of patients, which requires alterations to treatment regimens that are often less effective. The kidney’s function is to provide fluid homeostasis, and this is an energy-intensive process. Proper renal function is dependent on functional mitochondria. PGC-1α regulates mitochondrial number, respiratory capacity, and mitochondrial proteins in proximal tubule cells. We delivered low-dose cisplatin to mice via intraperitoneal injections once a week for 4 weeks. The mice were then …

Baricitinib In The Treatment Of A Critical Patient With Covid-19 Pneumonia: A Case Report, Nishant Patel, Dylan Goldsmith, Forest W. Arnold

The University of Louisville Journal of Respiratory Infections

A 72-year-old male presented to the emergency department with a chief complaint of diarrhea after having tested positive for COVID-19 two days prior. He initially had minimal respiratory complaints, but was eventually transferred to the intensive care unit for acute hypoxic respiratory failure. In addition to dexamethasone, remdesivir, and antibiotics, the patient was treated with baricitinib, a Janus kinase inhibitor that was recently granted emergency use authorization by the Food and Drug Administration for treatment of hospitalized patients with COVID-19. He had an extensive and complicated hospital course and had to be placed on mechanical ventilation, ultimately undergoing tracheostomy. After …

Dysregulation Of Systemic Immunity In Aging And Dementia, Jenny Lutshumba, Barbara S. Nikolajczyk, Adam D. Bachstetter

Pharmacology and Nutritional Sciences Faculty Publications

Neuroinflammation and the tissue-resident innate immune cells, the microglia, respond and contribute to neurodegenerative pathology. Although microglia have been the focus of work linking neuroinflammation and associated dementias like Alzheimer’s Disease, the inflammatory milieu of brain is a conglomerate of cross-talk amongst microglia, systemic immune cells and soluble mediators like cytokines. Age-related changes in the inflammatory profile at the levels of both the brain and periphery are largely orchestrated by immune system cells. Strong evidence indicates that both innate and adaptive immune cells, the latter including T cells and B cells, contribute to chronic neuroinflammation and thus dementia. Neurodegenerative hallmarks …

Cd151 Drives Cancer Progression Depending On Integrin Α3Β1 Through Egfr Signaling In Non-Small Cell Lung Cancer, Jianjie Zhu, Tingting Cai, Jieqi Zhou, Wenwen Du, Yuanyuan Zeng, Ting Liu, Yulong Fu, Yue Li, Qian Qian, Xiuwei H. Yang, Qinglin Li, Jian-An Huang, Zeyi Liu

Pharmacology and Nutritional Sciences Faculty Publications

Background
Tetraspanins CD151, a transmembrane 4 superfamily protein, has been identified participating in the initiation of a variety of cancers. However, the precise function of CD151 in non-small cell lung cancer (NSCLC) remains unclear. Here, we addressed the pro-tumoral role of CD151 in NSCLC by targeting EGFR/ErbB2 which favors tumor proliferation, migration and invasion.

Methods
First, the mRNA expression levels of CD151 in NSCLC tissues and cell lines were measured by RT-PCR. Meanwhile, CD151 and its associated proteins were analyzed by western blotting. The expression levels of CD151 in NSCLC samples and its paired adjacent lung tissues were then verified …

Synphilin-1 And Its Effects On Pathogenesis Of Parkinson’S Disease, Mirghani Mohamed

Honors Scholar Theses

Parkinson's Disease (PD) is a progressive neurodegenerative and movement disorder primarily caused by the degradation of dopaminergic neurons. Known markers of neurodegeneration in PD are Lewy Bodies, which are fibrillar aggregates that are found in the brains of PD patients. Lewy Bodies can accumulate from specific mutations in the SNCA gene that codes for alpha-synuclein, a protein enriched in presynaptic neurons. A mutated SNCA gene can cause conformational aggregates of alpha-synuclein to form toxic species mediating neuronal death. Research into alpha-synuclein has led to the discovery of a binding partner known as synphilin-1 that is also found in protein aggregates …

Identification Of Binding Regions Of Bilirubin In The Ligand-Binding Pocket Of The Peroxisome Proliferator-Activated Receptor-A (Pparalpha), Darren M. Gordon, Stephen H. Hong, Zachary A. Kipp, Terry D. Hinds Jr.

Pharmacology and Nutritional Sciences Faculty Publications

Recent work has shown that bilirubin has a hormonal function by binding to the peroxisome proliferator-activated receptor-α (PPARα), a nuclear receptor that drives the transcription of genes to control adiposity. Our previous in silico work predicted three potential amino acids that bilirubin may interact with by hydrogen bonding in the PPARα ligand-binding domain (LBD), which could be responsible for the ligand-induced function. To further reveal the amino acids that bilirubin interacts with in the PPARα LBD, we harnessed bilirubin’s known fluorescent properties when bound to proteins such as albumin. Our work here revealed that bilirubin interacts with threonine 283 (T283) …

Pharmacogenetic Testing In Patients With Autism Spectrum Disorder Evaluated In The Children’S Mercy Hospital Goldiloks© Clinic, Rachel Goodson

Research Days

Background: Autism Spectrum Disorder (ASD) affects 1 in 54 children in the United States. Children with ASD are more likely to be diagnosed with co-occurring mental health disorders. There is currently little research guiding medication choice and dosing in patients with ASD. Children with ASD are at increased risk for reduced clinical response and adverse reaction (including due to polypharmacy). Pharmacogenomics is an approach for medication decision making that leverages an individual’s genetic information and clinical presentation to make informed choices, but no studies have specifically investigated the outcomes of PGX for patients with ASD. Understanding the clinical and genetic …

Case Presentation: Lower Back Pain Or Chronic Acetaminophen Overdose?, Meghan Whitt, Christopher Schwartz, Bhumi Shah

Rowan-Virtua Research Day

Unintentional ingestions can pose a difficult challenge to diagnose in the setting of the Emergency Department. Many may present with vague symptoms that are not consistent with classic overdose prodromes. Many patients do not identify or disclose over the counter medications, such as analgesics, with which acute/chronic ingestion in large quantities can result in life threatening medical emergencies. Their underlying symptoms may also cloud their clinical picture, further complicating workup within the ED.

Choline-Sigma-1r As An Additional Mechanism For Potentiation Of Orexin By Cocaine, Jeffrey Barr, Pingwei Zhao, G Cristina Brailoiu, Eugen Brailoiu

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Orexin A, an endogenous peptide involved in several functions including reward, acts via activation of orexin receptors OX₁ and OX₂, Gq-coupled GPCRs. We examined the effect of a selective OX₁ agonist, OXA (17-33) on cytosolic calcium concentration, [Ca²⁺ ]_i, in neurons of nucleus accumbens, an important area in the reward circuit. OXA (17-33) increased [Ca²⁺ ]_i in a dose-dependent manner; the effect was prevented by SB-334867, a selective OX₁ receptors antagonist. In Ca²⁺-free saline, the OXA (17-33)-induced increase in [Ca²⁺ ]_i was not affected by pretreatment …
