Objectives/Goal: In this study, we explored 2-D phase contrast non-invasive magnetic resonance imaging (MRI) to measure hepatic blood flow in children with and without obesity.
Methods/Design: In this IRB-approved study, we imaged pediatric patients with abdominal MRI with 2D phase contrast imaging of the descending aorta (AO) at the diaphragm, the inferior vena cava (IVC) at the right atrium, and inferior to hepatic drainage above the renal vein confluence …
Brash Syndrome Case Report And Brief Review,
2023
Rowan University
Brash Syndrome Case Report And Brief Review, Kelly Schuitema
Stratford Campus Research Day
BRASH syndrome is an acronym that stands for bradycardia, renal failure, AV node blocker, shock and hyperkalemia. The syndrome is precipitated by synergism from AV nodal blocking agents and hyperkalemia. The combination of the AV nodal blockade and renal failure leads to a cycle of severe bradycardia and hyperkalemia. We will discuss a case of BRASH syndrome with a 68 year old female who presented with generalized weakness and was found to be hypotensive, bradycardia, in acute renal failure with hyperkalemia likely related to metoprolol and amlodipine use.

The Role Of Food Accessibility In Weight Loss In A Rat Model Of Parkinson’S Disease, Anjali Kikkisetti, Nicole Charles, Francois Gould
Stratford Campus Research Day
Parkinson’s disease (PD) is a neurodegenerative disorder that causes a variety of motor and non-motor symptoms. The goal of this project was to understand whether the weight loss seen with Parkinson’s disease was due to the lack of being able to access the food because of the food placement or because of inability to chew the food due to degeneration of muscles required for chewing food. Both treatment groups, Adjusted Diet and Unadjusted Diet, lost weight after injections started, whereas control weights were stable throughout the experiment. There is no statistically significant difference in weight loss between adjusted and unadjusted …

The Correlation Between Serum C-Reactive Protein Level And Risk Of Future Cardiovascular Disease: A Neurodivergent Population Dilemma, Brandon Cunha, Andrea Iannuzzelli, Venkateswar Venkataraman
Stratford Campus Research Day
Extensive research on neurotypical (NT) populations has demonstrated that a chronically elevated level of serum C Reactive Protein (CRP) is a strong predictor of future cardiovascular disease (CVD). Interestingly, many neurodivergent (ND) populations experience chronically elevated CRP levels higher than NT controls. Current research is concerned with establishing the significance of this relationship to accurately predict CVD risk for potentially at risk ND patients. To contribute to this gap in knowledge, the Rowan-Virtua Regional Integrated Special Needs (RISN) Center patient population will be studied to identify trends in baseline serum CRP levels across a multitude of ND conditions. A clinical …

University of Arkansas, Fayetteville
Development Of A Computational Model To Investigate Pathways And The Effects Of Treatment In Fanconi Anemia, Sabrina Kellett
Biological Sciences Undergraduate Honors Theses
Fanconi Anemia (FA) is a rare type of anemia that is not easily studied and can have very detrimental effects. This disease compromises the bone marrow, resulting in decreased hemopoiesis. Symptoms of FA also include abnormalities in the brain and spinal cord, incorrect formation of the kidneys, abnormal formation of the heart and lungs, and a dramatically increased risk of developing cancer. FA can be caused by various mutations in any of the 22 genes that encode for proteins involved in what is called the FA DNA repair pathway. In healthy individuals, this pathway specifically repairs interstrand cross-links (ICLs) recognized …

A Phenomenological Take On Mirror Self-Face Perception In Schizophrenia, Giovanni Pennisi
Journal of Mind and Medical Sciences
Studies concerning social deficits in schizophrenia has often been restrained to exploring facial recognition. Various investigations have shown that those diagnosed with schizophrenia have difficulties in perceiving the identities and emotions of those around them merely through observing their facial features. A few others have also taken into account the issue of self-face recognition in individuals with schizophrenia, finding that their capacity to associate photos or videos of their own face to themselves is hindered due to the illness. However, to my knowledge, only a few studies have so far delved into the intricacies of how individuals with schizophrenia or …

The Effects Of Exercise On The Lipid Profile Of Extracellular Vesicles, Tesha Kerr
Nutrition & Health Sciences Dissertations & Theses
We sought to ascertain the effect of different types of exercise (aerobic training and resistance training) on the lipid profile of extracellular vesicles. Thus, we had participants perform bouts of AT and RT and rest (control) and collected blood samples from them immediately after (timepoint 0) and 30 minutes after (timepoint 30) exercise. Small extracellular vesicles (sEVs) were isolated from plasma of participants using cushioned-density gradient ultracentrifugation (C-DGUC). Small EV size, morphology, and protein markers were determined using nanoparticle tracking analysis, transmission electron microscopy, and western blot, respectively. Additionally, we performed untargeted lipidomics on the sEV isolate. We found that …

Endogenously produced hydrogen sulfide (H2S) is critical for cardiovascular homeostasis. Therapeutic strategies aimed at increasing H2S levels have proven cardioprotective in models of acute myocardial infarction (MI) and heart failure (HF). The present study was undertaken to investigate the effects of a novel H2S prodrug, SG-1002, on stress induced hypertrophic signaling in murine HL-1 cardiac muscle cells. Treatment of HL-1 cells with SG-1002 under serum starvation without or with H2O2 increased the levels of H2S, H2S producing enzyme, and cystathionine β-synthase (CBS), as well as antioxidant protein levels, such as super oxide dismutase1 (SOD1) and catalase, and additionally decreased oxidative …

Ideal Body Weight And Body Fat Percentage Predict Relative Energy Deficiency In Sport (Red-S) Scores In Collegiate Athletes, Emily Norman
Theses and Dissertations--Dietetics and Human Nutrition
Background: Low energy availability (LEA) is the underlying cause of Relative Energy Deficiency in Sport (RED-S) which negatively affects athletes' physiological function, health, and performance. RED-S results from inadequate dietary intake to support energy expenditure for daily living, growth, and optimal performance. It occurs in both male and female athletes, with or without disordered eating. However, screening and diagnosis in athletes can be difficult. Objective: This study aims to identify strong predictors of RED-S and assess its prevalence in collegiate male and female athletes. Methods: A total of 270 NCAA athlete test points from mixed sports were evaluated for RED-S …

Contribution Of Metabolic Cell Swelling On Microcirculatory Perfusion In Septic Shock, Charles E. Payne
Theses and Dissertations
Sepsis, a systemic immunological response that leads to organ-dysfunction, the development of septic shock, and death has mortality rate of 15-25%. A subset of sepsis, septic shock, has an in-hospital mortality rate of 30-50%. Sepsis and its treatment are the most expensive healthcare problem in the United States with the US Agency for Healthcare Research and Quality estimating annual costs over $20 billion. Hypoxia experienced in septic shock induces metabolic cell and tissue swelling leading to further microcirculatory dysfunction and poor tissue perfusion. Reversing metabolic cell swelling corrects these perfusion defects. Two models were used in rats to induce septic …

Reducing Placental Oxidative Stress In A Rat Model Preeclampsia Using Vegfr2 Nanoparticles, Sophia Ganios
Williams Honors College, Honors Research Projects
Preeclampsia is a complication of pregnancy, where the placenta lacks sufficient blood flow due to abnormal formation of the vascular endothelial cells. This results in hypertension and increased reactive oxygen species, causing oxidative stress. The VEGF (vascular endothelial growth factor) helps develop new growth, so by increasing the receptors VEGFR2 by injection of LTP nanoparticles into the uterine wall of RUPP rats, one can see if there would be improvement in the otherwise reduced uterine pressure pregnant rat. This would be confirmed by the 8-isoprostane test, which measures oxidative stress.

Noninvasive Quantification Of Tissue Sodium Concentration In The Kidney Disease Spectrum Using 23na Magnetic Resonance Imaging, Fabio R. Salerno
Electronic Thesis and Dissertation Repository
Chronic kidney disease (CKD), especially when requiring kidney replacement therapy (hemodialysis (HD) and peritoneal dialysis (PD)), is associated with extracellular water expansion with increased total body sodium. Sodium can also be accumulated in tissues independently of extracellular water. Sodium-23 magnetic resonance imaging (23Na MRI) can quantify the concentration of sodium nuclei in tissues. Applied to the human leg, quantification of tissue sodium concentrations mainly at the skin and muscle level is possible. We hypothesized that increased tissue sodium concentrations exert toxic effects in CKD and dialysis. We aimed to (1) compare tissue sodium concentrations in adults, children and …

Worried Sick: Understanding The Implications Of Stress On A Physiological Level, Julia Saia
Senior Honors Theses
Stress is prevalent among many individuals in today’s society. A literature review was conducted to investigate the physiological effects of stress, including the biomarkers of stress and how these interact with various body systems. The stress response is a protective mechanism to prepare the body to adequately respond to a perceived threat. However, when this response is prolonged, it begins to have a maladaptive effect on the body and can cause more harm than good. This literature review sought to compile what is known regarding the general effects of chronic stress and its impact on the nervous, immune, digestive, and …

Motoneuron Excitability Dysfunction In Als: Pseudo-Mystery Or Authentic Conundrum?, Sherif M. Elbasiouny
Neuroscience, Cell Biology & Physiology Faculty Publications
In amyotrophic lateral sclerosis (ALS), abnormalities in motoneuronal excitability are seen in early pathogenesis and throughout disease progression. Fully understanding motoneuron excitability dysfunction may lead to more effective treatments. Yet decades of research have not produced consensus on the nature, role or underlying mechanisms of motoneuron excitability dysfunction in ALS. For example, contrary to Ca excitotoxicity theory, predictions of motoneuronal hyper-excitability, normal and hypo-excitability have also been seen at various disease stages and in multiple ALS lines. Accordingly, motoneuron excitability dysfunction in ALS is a disputed topic in the field. Specifically, the form (hyper, hypo or unchanged) and what role …

Spaceflight poses risks to the central nervous system (CNS), and understanding neurological responses is important for future missions. We report CNS changes in Drosophila aboard the International Space Station in response to spaceflight microgravity (SFmg) and artificially simulated Earth gravity (SF1g) via inflight centrifugation as a countermeasure. While inflight behavioral analyses of SFmg exhibit increased activity, postflight analysis displays significant climbing defects, highlighting the sensitivity of behavior to altered gravity. Multiomics analysis shows alterations in metabolic, oxidative stress and synaptic transmission pathways in both SFmg and SF1g; however, neurological changes immediately postflight, including neuronal loss, glial cell count alterations, oxidative …
