Tiny But Mighty, An Exploration Of Microbes And Plants As Sources Of Small Novel Bioactive Compounds Against Invasive Mycoses., Hannah Mai Peacock, James Anthony O'Connor
SURE Journal: Science Undergraduate Research Experience Journal
Despite the high mortality rate involved with invasive cerebral mycoses, there is a relative lack of research available around antifungals capable of crossing the blood brain barrier.
In this study the metabolites of four plants (Crocus vernus, Miniature Narcissus (daffodil), Osmanthus delavayi and Taraxacum officinale (common dandelion)) and two bacteria (Lacticaseibacillus paracasei and Staphylococcus epidermidis) were extracted and assayed for antifungal activity against Candida albicans and Saccharomyces cerevisiae. Thin layer chromatography and bioautography were then employed to assess the activity of the constituent components of sources showing antifungal activity.
Metabolites of S.epidermidis, and extracts …

Bisphenol-A And Phthalate Metabolism In Children With Neurodevelopmental Disorders, T Peter Stein, Margaret D Schluter, Robert A Steer, Xue Ming
Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship
BACKGROUND: The etiology of autism spectrum (ASD) and Attention Deficit/Hyperactivity (ADHD) disorders are multifactorial. Epidemiological studies have shown associations with environmental pollutants, such as plasticizers. This study focused on two of these compounds, the Bisphenol-A (BPA) and Diethylhexyl Phthalate (DEHP). The major pathway for BPA and DEHP excretion is via glucuronidation. Glucuronidation makes insoluble substances more water-soluble allowing for their subsequent elimination in urine.
HYPOTHESIS: Detoxification of these two plasticizers is compromised in children with ASD and ADHD. Consequently, their tissues are more exposed to these two plasticizers.
METHODS: We measured the efficiency of glucuronidation in three groups of children, …
Sex Differences In Mood And Anxiety-Related Outcomes In Response To Adolescent Nicotine Exposure, Tsun Hay Jason Ng
Sex Differences In Mood And Anxiety-Related Outcomes In Response To Adolescent Nicotine Exposure, Tsun Hay Jason Ng
Electronic Thesis and Dissertation Repository
Nicotine dependence is causally linked to increased risk of mood/anxiety disorders in later life. Females are reported to experience a higher prevalence of anxiety/depressive disorders and challenges in smoking cessation therapies, suggesting a potential sex-specific response to nicotine exposure and mood/anxiety disorder risk. However, pre-clinical evidence of sex-specific responses to adolescent nicotine exposure is unclear. Thus, to determine any sex differences in anxiety/depressive-related outcomes, adolescent male and female Sprague Dawley rats received nicotine (0.4 mg/kg; 3x daily) or saline injections for 10 consecutive days, followed by behavioural testing, in-vivo electrophysiology and Western Blot analyses. Our results revealed that adolescent nicotine …

Advances in Clinical Medical Research and Healthcare Delivery
The dangers of marijuana use are well documented across most body systems. We report a 27-year-old male who ingested marijuana and then experienced an ST-elevation myocardial infarction, subsequent cerebrovascular accident, and death within the span of a week. Toxicology reports were positive for THC only, echocardiography revealed diffuse hypokinesis with an ejection fraction estimated at 15-20%, and troponins peaked at greater than 270,000 pg/mL. Due to decreased Glasgow Coma Score and hemodynamic instability, the patient was not taken for cardiac catheterization, but was subsequently sedated, intubated, and placed on pressor support in the ICU. Initial brain imaging was negative for …

Release The Kratom: Post-Acute Withdrawal Syndrome In A 70 Year Old Male, Nardin El-Shammaa, Kyle Street, Narshima Pinninti
Rowan-Virtua Research Day
Centuries in Eastern medicine.. Kratom has been commonly used for chronic pain and opiate withdrawal symptoms with first reported cases in the United States in the early 2000s. It is a plant that consists of psychoactive alkaloids that target opioid receptors with different affinity. Effects from Kratom are dose-dependent, at lower doses, it acts as a stimulant, while at higher doses produces analgesia and euphoria. Although Kratom is legal and easily accessible over the counter, there have been increasing reports of potential for addiction and toxicity. Cessation of Kratom can result in withdrawal symptoms similar to opiate withdrawal. Here we …

Journal of Patient-Centered Research and Reviews
Purpose: Dual antiplatelet therapy is standard for patients undergoing percutaneous coronary intervention (PCI) with stents. Traditionally, patients swallow the loading dose of a P2Y12 inhibitor before or during PCI. Time to achieve adequate platelet inhibition after swallowing the loading dose varies significantly. Chewed tablets may allow more rapid inhibition of platelet aggregation. However, data for this strategy in patients with stable ischemic heart disease or non-ST-elevation acute coronary syndrome (NSTE-ACS) are less robust.
Methods: In this single-center prospective trial, 112 P2Y12-naïve patients with stable ischemic heart disease or NSTE-ACS on aspirin therapy and who received ticagrelor after coronary angiography but …

Accelerometry-Based Analysis Of Postural Sway In Parkinson's Disease Patients With Levodopa-Induced Dyskinesia, Chandler Brock
UNO Student Research and Creative Activity Fair
Parkinson’s disease (PD) is a progressive neurodegenerative disorder, with patient numbers projected to double to 12 million in the next 20 years. Levodopa-induced dyskinesia (LID) is a major problem associated with the long-term use of levodopa for symptomatic treatment of PD. These involuntary movements can become disabling and may interfere with quality of life. Our prior research showed that PD w/ LID were less stable while standing (i.e., increased postural sway) and had a higher incidence of falls. The aim of this study is to determine if postural sway properties are altered by LID via decomposing the sway signal. We …

Effects Of Chronic Cirrhosis Induced By Intraperitoneal Thioacetamide Injection On The Protein Content And Michaelis–Menten Kinetics Of Cytochrome P450 Enzymes In The Rat Liver Microsomes, Devaraj Venkatapura Chandrashekar, Barent N. Dubois, Mamunur Rashid, Reza Mehvar
Pharmacy Faculty Articles and Research
Chronic intraperitoneal injection of thioacetamide (TAA) in rats has been used as an animal model of human cirrhosis to study the effects of the disease on drug metabolism. However, TAA inhibits P450 enzymes directly and independently of cirrhosis. We investigated the effects of chronic cirrhosis in rats, induced by 10 weeks of intraperitoneal TAA, on the P450 enzymes after a 10-day washout period to eliminate TAA. Liver histology and serum biomarkers of hepatic function confirmed cirrhosis in all animals. Microsomal total P450 content, P450 reductase activity and ethoxycoumarin O-deethylase activity, a general marker of P450 activity, were significantly reduced by …

The Role Of Reactive Oxygen Species In The Accumulation Of Driver Mutations In B Cell Acute Lymphoblastic Leukemia, Mia P. Sams
Electronic Thesis and Dissertation Repository
B cell acute lymphoblastic leukemia (B-ALL) is the most prevalent type of cancer in young children and is associated with recurrent mutations and high levels of reactive oxygen species (ROS). The antioxidant N-acetylcysteine was tested for its ability to prolong lifespan of a mouse model of B-ALL and reduce frequency of mutations. Mice treated with 1g/L of N-acetylcysteine in drinking water were found to have delayed onset of B-ALL at 11 weeks of age and changes in gene expression relating to B cell development, calcium-apoptosis signaling, and pathways in cancer, although no differences in lifespan were observed. Tumours from treated …

Extracellular accumulation of amyloid-beta (Aβ) plaques is one of the major pathological hallmarks of Alzheimer's disease (AD), and is the target of the only FDA-approved disease-modifying treatment for AD. Accordingly, the use of transgenic mouse models that overexpress the amyloid precursor protein and thereby accumulate cerebral Aβ plaques are widely used to model human AD in mice. Therefore, immunoassays, including enzyme-linked immunosorbent assay (ELISA) and immunostaining, commonly measure the Aβ load in brain tissues derived from AD transgenic mice. Though the methods for Aβ detection and quantification have been well established and documented, the impact of the size of the …

Theses & Dissertations
Forkhead box M1 (FOXM1) is a member of the conserved forkhead box (FOX) transcription factor family. Over the last two decades, FOXM1 has emerged as a multifunctional oncoprotein and a robust biomarker of poor prognosis in many human malignancies. FOXM1 and its associated oncogenic transcriptional signature are enriched in >85% of ovarian cancer cases, and FOXM1 expression and activity can be enhanced by a plethora of genomic, transcriptional, post-transcriptional, and post-translational mechanisms. As a master transcriptional regulator, FOXM1 promotes critical oncogenic phenotypes in ovarian cancer, including: (1) cell proliferation, (2) invasion and metastasis, (3) chemotherapy resistance, (4) cancer stem cell …

In the neonatal population, RDS can be classified as NRDS (Neonatal respiratory distress syndrome), while in adults, it is known as ARDS (acute respiratory distress syndrome). This dissertation examines a therapeutic approach to NRDS and a mechanistic approach to ARDS with in vivo and in vitro models of lung injury. NRDS is characterized by a deficiency or lack of surfactant. Surfactant is an essential compound composed of phospholipids and proteins to prevent the lungs from collapsing. There are several …
Effectiveness Of Stabilized Hypochlorous Acid In Acute Peritonitis Treatment: A Murine Surgical Study, Benjamin Michael Pomeroy
Effectiveness Of Stabilized Hypochlorous Acid In Acute Peritonitis Treatment: A Murine Surgical Study, Benjamin Michael Pomeroy
MSU Graduate Theses
Peritonitis is an inflammatory condition affecting the mesothelial cells that line the peritoneal cavity and is commonly induced by bowel perforations. This medical emergency is treated through antibiotic therapy and surgical intervention followed by tissue irrigation (lavage). Acute treatments aim to remove the bacterial burden, however recurring peritoneal infections occur at high rates and contribute to patient morbidity. These recurring infections are likely due to the inability of lavage solutions to remove the entire massive intra-abdominal bacterial load due to intestinal perforation. Numerous antiseptic solutions and antibiotic additives have been evaluated in their ability to improve source control by abdominal …
Comparative Metabolism Of Aflatoxin B1 In Two Quail Genera Coturnix Japonica And Callipepla Californica, Sean Moody
Comparative Metabolism Of Aflatoxin B1 In Two Quail Genera Coturnix Japonica And Callipepla Californica, Sean Moody
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Avian species are highly susceptible to the hepatotoxic mycotoxin aflatoxin B1 (AFB1). Domesticated turkeys are exquisitely sensitive, due to a combination of highly-efficient hepatic cytochrome P450 (CYP)-mediated bioactivation, and to dysfunctional alpha-class glutathione S-transferases (GSTAs) which typically detoxify the bioactivated electrophilic metabolite exo-AFB1-8,9-epoxide (AFBO). Wild turkeys are relatively resistant to AFB1 in large part due to expression of functional GSTAs. Quail, a related Galliforme, are slightly less sensitive in vivo to AFB1, but whether this is related to the hepatic metabolic profiles of these two critical enzymes has not been rigorously evaluated. …

Pharmacy Faculty Articles and Research
The endothelial cells which form the inner cellular lining of the vasculature can act as non-professional phagocytes to ingest and remove emboli and aged/injured red blood cells (RBCs) from circulation. We previously demonstrated an erythrophagocytic phenotype of the brain endothelium for oxidatively stressed RBCs with subsequent migration of iron-rich RBCs and RBC degradation products across the brain endothelium in vivo and in vitro, in the absence of brain endothelium disruption. However, the mechanisms contributing to brain endothelial erythrophagocytosis are not well defined, and herein we elucidate the cellular mechanisms underlying brain endothelial erythrophagocytosis. Murine brain microvascular endothelial cells (bEnd.3 …
