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 …

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.

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 …

Pharmaceutical Science and Research
Despite widespread interest in chemoprevention and therapy due to the high margin of safety of dietary natural compounds, clinical intervention with single agents has failed to yield the expected outcomes, mostly due to poor bioavailability and low potency. Combinations of natural agents with synergistic effects are gaining increasing attention. In the present study, in vitro and in vivo antitumor effects of a combination of two natural dietary agents, green tea epigallocatechin gallate (EGCG) and resveratrol were investigated. It was revealed that their combination at low doses (at which single agents induce minimal apoptosis) synergistically increased apoptosis (combination index < 1) in head and neck cancer cell lines. Synergistic apoptosis was also supported by caspase‑3 and PARP cleavage. The combination also significantly inhibited growth of xenografted head and neck tumors in nude mice as supported by significant inhibition of tumor volume, tumor weight and Ki67 expression, and increase in TUNEL‑positive cells. Mechanistic studies revealed that the combination inhibited AKT‑mTOR signaling both in vitro …

Delineating The Upc2a Regulon In Candida Glabrata, Yu Li
Theses and Dissertations (ETD)
Candida glabrata is the second most common cause of invasive candidiasis. Intrinsic resistance has greatly limited the utility of the triazole antifungal, fluconazole, in the treatment of invasive fungal infection. The transcription factor Upc2 regulates the expression of sterol biosynthesis genes in yeast. Disrupting UPC2A in C. glabrata greatly increases its susceptibility to fluconazole (FLU) in both FLU-susceptible and -resistant clinical isolates. Therefore, the Upc2A and its target genes represent a potential pathway for overcoming FLU resistance in C. glabrata. We aimed to delineate the Upc2A regulon to determine its target genes involved in FLU resistance. Transcriptome sequencing (RNA-seq) analysis …

The Effects Of Progesterone Induced Blocking Factor And 17-Hydroxyprogesterone Caproate On The Pathophysiology Of Preeclampsia, Kyleigh M. Comley
Honors Theses
Preeclampsia (PE) is responsible for about 20% of the 13 million preterm births each year worldwide, including 100,000 cases annually in the United States. Despite being a leading cause of maternal and perinatal morbidity, the mechanisms of pathogenesis are still largely unknown. PE is progesterone deficient state characterized by hypertension, chronic immune activation, endothelial dysfunction and severe forms can lead to seizures. Treatment of seizures includes the administration of magnesium sulfate (MgSO4) though not all PE patients are responsive, and it does not decrease PE-associated hypertension. To resolve these conditions, PE patients are delivered early thereby making PE the leading …

Uvb-Induced Microvesicle Particle Release In Human Skin In Vivo Is Diminished Following Oral Vitamin C And E Antioxidant Administration, Benjamin Schmeusser, Cameron Mcglone, Jeffrey B. Travers
Medical Student Research Symposium Abstracts and Posters
An important question in photobiology asks how Ultraviolet B (UVB, 290 – 320 nm) radiation, which mostly absorbs in the outer epidermis of skin, can generate a systemic response such as immunosuppression. Previous in vitro and ex vivo studies demonstrate UVB-dependent release of bioactive molecule-containing microvesicle particles (MVPs) from keratinocytes. Furthermore, MVP release is diminished upon antioxidant administration. The purpose of this study is to examine UVB-induced MVP release and antioxidant response in vivo. In this IRB-approved study, 8 male participants with Fitzpatrick type I or II skin were treated with 1000 J/m2 UVB irradiation to a 5 by 5 …

Type 2 diabetes mellitus has become a serious medical challenge of the 21st century with a dramatic surge in diabetes cases since the last decade. It accounts for 90-95% of all cases of diabetes mellitus. The interplay between insulin resistance and beta cells dysfunction plays a crucial role in the pathophysiology of diabetes mellitus. Type 2 diabetes mellitus is characterized by peripheral insulin resistance in skeletal muscles that leads to a constellation of metabolic disorders, and exhaustion of pancreatic beta cells to maintain euglycemia. The inability of pancreatic beta cells to compensate insulin demand in an insulin-resistant state, result in …

Estrogen signaling is crucial for breast cancer initiation and progression. Endocrine-based therapies comprising estrogen receptor (ER) modulators and aromatase inhibitors remain the mainstay of treatment. This study aimed at investigating the antitumor potential of the most potent compounds in citrus peels on breast cancer by exploring their anti-estrogenic and anti-aromatase activities. The ethanolic extract of different varieties of citrus peels along with eight isolated flavonoids were screened against estrogen-dependent breast cancer cell lines besides normal cells for evaluating their safety profile. Naringenin, naringin and quercetin demonstrated the lowest IC50s and were therefore selected for further assays. In silico molecular modeling …

Introduction
Methamphetamine associated cardiomyopathy (MAC) and peripartum cardiomyopathy (PPCM) are both rare obstetric conditions. Literature regarding methamphetamine associated cardiomyopathy in the obstetric population is limited, and it can be difficult to make the distinction between the two given the similarities in clinical presentation. However similar, there are significant distinctions in the pathophysiology of these two that can help clinicians with the management process.
