Fucoxanthin: A Review Of Potential Benefits Relative To Human Health, Michael R. White

Masters Theses, 2020-current

Fucoxanthin is a carotenoid sourced and extracted mainly from dark orange and brown seaweeds found in the pacific ocean, such as the wakame algae. The allenic bonds and unique oxygen groups give fucoxanthin its unique structure and are thought to be part of the reason fucoxanthin has unique physiological functions. Fucoxanthin has potentially numerous effects on the physiology of human health, ranging from skin health to metabolic health, which have been demonstrated in animal model research. The goal of this review is to examine current literature to discuss fucoxanthin’s potential application as a nutraceutical, treatment for obesity, type 2 diabetes, …

U-251mg Spheroid Generation Using Low Attachment Plate Method Protocol, Lara J. Carroll, Brijesh K. Tiwari, James F. Curtin, Janith Wanigasekara

Articles

3D cell culture is a process used to grow cells in vitro to mimic an in vivo environment. 3D cell models are very useful for understanding disease mechanisms and exploring drug therapeutics. 3D cultures can be grown from cells taken from cancer organoids in patients. Once grown, they can be used to screen for small molecule drugs or they can be genetically modified in order to analyse disease pathways or predict the toxicity or efficacy of a drug treatment. These cultures decrease the need to use animals in research and provides more reliable results as it uses human physiology. This …

Mitochondrial Distribution Of Glycine Receptors In Motor Neuron Cell Lines, Katsiaryna Milashevich

Student Theses and Dissertations

Although non-essential, glycine plays an important role in major metabolic reactions and is most known for its anti-inflammatory effects. An accumulation of contemporary research has shown that glycine is able to stabilize membrane potential using glycine receptors at the cellular level and to protect mitochondrial function directly, whether it is from inflammation, heavy metal poisoning, or ischemia-induced neuroinflammation. In this research, the existence of a hypothetical mitochondrial glycine receptor is examined. Immunofluorescence imaging was used to examine the presence of the glycine receptor subunits alpha 1 and alpha 2 in both non- differentiated and differentiated neuroblastoma cell lines. The preliminary …

Simian Varicella Virus Antibody Response In Recombinant Svv-Siv Immunized Primates, Kiser Horne

Honors Theses

Since its emergence in the early 1980’s HIV has killed approximately 32 million people, and continues to kill over half a million people every year. Significant research into potential vaccines and cures for HIV has been ongoing for decades but has been largely unsuccessful. One of the more promising technologies that is being investigated to develop an HIV vaccine is recombinant vaccine technology. The study presented in this thesis aims to use simian varicella virus (SVV) and simian immunodeficiency virus (SIV) to act as a model for recombinant vaccine development. If a recombinant SVV-SIV vaccine can be proven safe and …

The Role Of Environmental Stressors Experienced During Childhood In The Development Of Dissociative Identity Disorder, Jazmin Conway

PCOM Capstone Projects

The purpose of this research was to determine how environmental stressors that occur during the early childhood years can lead to the development of Dissociative Identity Disorder (DID) and diagnosis in the adult years. Over the years, childhood trauma has become increasingly prevalent worldwide and despite this increase, continues to remain a significantly unaddressed public health issue (Beilharz et al., 2020). The trauma experienced can include physical, sexual, emotional, and either physical or emotional neglect from a caregiver (Beilharz et al., 2020). Over the years, DID has been the center of controversy in the field of psychology. There have been …

Cyclin C Determines Cell Fate In Response To Oxidative Stress And Proteasome Inhibition, David C. Stieg

Graduate School of Biomedical Sciences Theses and Dissertations

In response to various sources of cellular stress, the coordination of intracellular events is necessary to elicit the appropriate molecular response. In particular, the reprogramming of gene expression by stress-specific transcription factors drives the activation of signaling pathways, triggering either cell survival or regulated cell death pathways. The Cdk8 kinase module (CKM) is a highly conserved transcriptional regulatory complex with a role in this decision. The CKM is composed of Cdk8, its activating partner cyclin C, and two scaffold proteins, Med12 and Med13. The CKM is a detachable subunit of the Mediator complex, which interacts with RNA polymerase II to …

Molecular And Genetic Studies Of Robo2 Transcriptional Regulation In The Central Nervous System Of Drosophila Melanogaster, Muna Abdal Rahim Abdal Rhida

Graduate Theses and Dissertations

Drosophila Robo2 axon guidance receptor is a member of the evolutionarily conserved Roundabout (Robo) protein family that is involved in directing axons that cross the midline to the other side of the animal body. Robo2 roles mainly depend on two factors: The functional domains of the Robo2 protein, which is extensively studied, and the dynamic transcription of robo2 in various subsets of cells throughout embryogenesis which is not fully understood. Thus, knowing robo2 enhancers that transcriptionally regulate robo2 during embryogenesis is significant. To investigate robo2 potential enhancers, we screened 17 transgenic lines of Drosophila that were generated by Janelia Research …

Temperature-Dependent Macrophage Activity In Rainbow Trout, Danica Mcgrevey

Biological Sciences Undergraduate Honors Theses

Fever is an essential component of the immune response. Fever enhances immune responses as well as creates an environment in which the body has advantages over pathogens. Macrophages are often the first cells that come in contact with pathogens, as they reside in tissues. They are important for their engulfment of pathogens that results in the digestion of the pathogen, but they also produce nitric oxide and cytokines that contribute to immune response in a variety of ways, including initiating adaptive immunity and directing the production and activity of other immune cells. We were curious about macrophages from other temperature …

Effects Of Appetitive, Pre-Exposed, And Novel Distracters On Interval Timing Behavior: Role Of Nomifensine Within The Prelimbic Cortex, Alexander R. Matthews

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Poor attentional focus harms the estimation of time within the seconds-to-minutes range, i.e. interval timing. Interval timing behavior is related to several cognitive functions including perception of the passage of time, decision making, and to memory processes. Harmful delays in timing are caused by distractions of attention, within the timing task in the form of novel, or familiar distracters, which may or may not have been previously conditioned. The purpose of this dissertation was to explore how attention to novel or familiar distractions within the timing task can be altered using catecholamine reuptake blocker nomifensine. The experiment in Chapter 3, …

The Role Of The Snail/Let-7 Axis In Stemness Induction In Distinct Subtypes Of Ovarian Cancer: The Search For Cancer Stem Cell Targeting Strategies, Hanmin Wang

Loma Linda University Electronic Theses, Dissertations & Projects

Epithelial ovarian cancer (EOC) has the one of the lowest survival rates, partly due to modern therapy’s failure to consider the heterogeneity of EOC and the failure to effectively target cancer stem cells (CSC). CSCs lead to cancer relapse and metastasis. Studies of stem cell reprogramming have linked let-7 repression and acquisition of stemness with the EMT factor, SNAI1. The mechanisms for the loss of let-7 in cancer cells are incompletely understood. We aimed to determine the mechanism of epithelialmesenchymal transition (EMT)-induced stemness in cancer cells. The central hypothesis for this study is that SNAI1 directly represses let-7, leading to …

Traumatic Brain Injury (Tbi): The Progressive Neurodegeneration And Mental Health Decline In United States Veterans, Andrew R. Wiener

PCOM Capstone Projects

Since the year 2000, the Defense and Veterans Brain Injury Center reported 414,000 documented cases of traumatic brain injuries (TBIs) among individuals serving in the United States Armed Forces (Defense and Veterans Brain Injury Center, 2020). Traumatic events to the head as a result from car accidents, falls, explosions, and gunshot wounds can lead to a disruption of normal cognitive functioning. Roughly 80% of diagnosed TBIs are mild in nature, commonly referred to as concussions, and can range from mild, moderate, severe, and penetrating (O’Neil et al., 2013). However due to the difficulty of diagnosing a TBI most cases go …

Sars-Cov-2 Infection’S Link To Behavior: A Review Of Coronaviruses And The Potential For Sars-Cov-2 To Damage The Brain’S Structure And Function, Grace Anne Wilgucki

PCOM Capstone Projects

Human Coronaviruses were discovered in the 1960s and were found to be a cause of the common cold, inducing mild symptoms on those infected (Santacroce et al., 2020). However, due to adaptation and co-evolution, more dangerous variations of Coronaviruses emerged in the early 2000s, causing severe infection of the respiratory tract (Ye et al., 2020). Notably, the outbreaks of severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) were devastating, as these HCoVs could inflict respiratory disease that can be fatal (Wong et al., 2016). Most recently, the emergence of a new strain of Human Coronavirus has taken …

Vitamin Deficiency And Depression, Maddison Jeffries

PCOM Capstone Projects

Depression, or major depressive disorder, has affected how people think, feel, and behave. As well as psychological problems, depression has also been a comorbid factor in other emotional and physiological disorders. The actual cause of depression is unknown. Researchers have worked to understand the connections and conditions a person may experience for depression to develop. One commonly researched path to depression is vitamin deficiency. A variety of vitamins like B6, B12, folate, and vitamin D have been linked extensively to depression as a possible cause. A continuation of research expands into how a deficiency of these vitamins causes depression. Low …

Neurological And Psychological Effects Of Covid-19 On Cognitive Impairment, Saba Mufti

PCOM Capstone Projects

Increasing evidence suggests that individuals affected with COVID-19 may be at high risk for developing long-term neurological consequences (Heneka et al., 2020). Psychological stress may also increase risk in cognitive impairment, which can lead to mental fatigue. However, research studies suggest that there is a relationship between physiological and psychological factors affecting cognitive function (Scott et al., 2015). The mechanistic understanding of neurological symptoms in patients affected with COVID-19 regarding whether they emerge from mental illness or directly from the invasion of SARS-CoV-2 into the central nervous system is limited (Mahammedi et al., 2020). Factors affecting the brain can lead …

The Neuroplasticity Of Depression: How Antidepressants And Cognitive Behavior Therapy (Cbt) Can Reverse Depression, Vahid Harbi

PCOM Capstone Projects

Depression is a complex disorder influenced by biological, psychological, and environmental factors (Santarelli et al., 2016). Depression is one of the most common forms of mental illness worldwide (WHO, 2021), yet the pathogenesis of depression and the mechanism of how antidepressants reverse depression remain unclear (Liu et al., 2017). The symptoms of depression are evident to most individuals, but the symptoms’ persistent nature remains a mystery to most. The four primary regions of the brain involved in depression are the Prefrontal Cortex (PFC), hippocampus, amygdala, and Anterior Cingulate Cortex (ACC) (Hayley et al., 2013). This review presents the prevailing literature …

Dabigatran Reduces Thrombin-Induced Neuroinflammation And Ad Markers In Vitro: Therapeutic Relevance For Alzheimer's Disease, Syed Waseem Bihaqi, Haripriya Vittal Rao, Abhik Sen, Paula Grammas

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Background: Vascular risk factors such as atherosclerosis, diabetes, and elevated homocysteine levels are strongly correlated with onset of Alzheimer's disease (AD). Emerging evidence indicates that blood coagulation protein thrombin is associated with vascular and non-vascular risk factors of AD. Here, we examined the effect of thrombin and its direct inhibitor dabigatran on key mediators of neuro-inflammation and AD pathology in the retinoic acid (RA)-differentiated human neuroblastoma cell line SH-SY5Y. Methods: SH-SY5Y cells exposed to thrombin concentrations (10–100 nM) +/- 250 nM dabigatran for 24 h were analyzed for protein and gene expression. Electrophoretic mobility shift assay (EMSA) was used to …

Medicinal Cannabis (Thc Vs. Cbd): Effects On Anxiety, Ptsd, And Epilepsy, Olivia Grace Griswold

PCOM Capstone Projects

As of November 4th, 2020, thirty-six states and four territories (District of Columbia, Guam, Puerto Rico, and U.S. Virgin Islands) have approved a measure that regulates cannabis for medicinal use (Markle & Nativio, 2019). In particular, Pennsylvania law allows residents with twenty-three different medical conditions to apply for an ID card that will enable them to purchase medical marijuana from dispensaries. Some of the medical conditions included are anxiety disorders, autism, epilepsy, and post-traumatic stress disorder (PTSD). As more states approve marijuana for medicinal use, researchers continue to investigate the interaction between medicinal cannabis and the endocannabinoid system.

The cannabis …

Component Causes Of Infectious Bovine Keratoconjunctivitis - The Role Of Moraxella Species In The Epidemiology Of Infectious Bovine Keratoconjunctivitis, John Dustin Loy, Matthew Hille, Gabriele Maier, Michael L. Clawson

School of Veterinary and Biomedical Sciences: Faculty Publications

Moraxella bovis can cause infectious bovine keratoconjunctivitis (IBK).

The role of M bovoculi in IBK is not fully understood.

M bovis and M bovoculi appear to undergo genetic recombination with each other or other members of the Moraxellaceae.

Recombination complicates their classification and potential role(s) in IBK pathogenesis.

MALDI-TOF MS is used to identify M bovis, 2 major strains or genotypes of M bovoculi, M ovis, and other members of the Moraxellaceae.

Classification and determination of pathogenesis potential within Moraxella species may be better understood through whole genome sequencing.

Exploring Downstream Effects Of Racial Trauma Leading To Ptsd: A Review Of Systemic Physiological And Neurobehavioral Alterations, Alexis Verwoert

PCOM Capstone Projects

Post-traumatic Stress Disorder (PTSD) is a debilitating psychiatric disease that often follows acute or chronic exposure to extreme stress. Hallmarks of this disorder include stressors, intrusion symptoms, avoidance, negative alterations in cognition and mood, and alterations in arousal and reactivity (Bovin, 2015). Since it was first defined in the Diagnostic and Statistical Manual of Mental Disorders-III (DSM-III), the diagnostic criteria for PTSD have evolved to encompass stressors as they may occur repeatedly across the lifespan (Bovin, 2015). Physiological and behavioral consequences of this extreme stress manifest themselves as systemic alterations in form and function. As is true of many diagnosable …

Acetyl-Coa And Metabolite Fluxes Regulate White Adipose Tissue Expansion, Jessica B Felix, Aaron R Cox, Sean M Hartig

Faculty, Staff and Students Publications

White adipose tissue (WAT) depends on coordinated regulation of transcriptional and metabolic pathways to respond to whole-body energy demands. We highlight metabolites that contribute to biosynthetic reactions for WAT expansion. Recent studies have precisely defined how byproducts of carbohydrate and lipid metabolism affect physiological and endocrine functions in adipocytes. We emphasize the critical emerging roles of short-chain fatty acids (SCFAs) and tricarboxylic acid (TCA) cycle metabolites that connect lipogenesis to WAT energy balance and endocrine functions. These insights address how adipocytes use small molecules generated from central carbon metabolism to measure responses to nutritional stress.

The Small Gtpase Rab-35 Facilitates The Initiation Of Phagosome Maturation And Acts As A Robustness Factor For Apoptotic Cell Clearance, Ryan Haley, Zheng Zhou

Faculty, Staff and Students Publications

We recently identified the novel function of the small GTPase RAB-35 in apoptotic cell clearance in Caenorhabditis elegans, a process in which dying cells are engulfed and degraded inside phagosomes. We have found that RAB-35 functions in two separate steps of cell corpse clearance, cell corpse recognition and the initiation of phagosome maturation. During the latter process, RAB-35 facilitates the removal of phosphatidylinositol-4,5-bisphosphate (PI(4,5)P2) from the membranes of nascent phagosomes and the simultaneous production of phosphatidylinositol-3-P (PI(3)P) on these same membranes, a process that we have coined the PI(4,5)P2 to PI(3)P shift. RAB-35 also promotes the recruitment of the …

The Importance Of Noncapped Viral Genomic Rna To Alphaviral Infection And Pathogenesis., Autumn Lapointe

Electronic Theses and Dissertations

Alphaviruses are mosquito-borne arboviruses that have a positive sense, single-stranded RNA genome, which are capable of causing severe disease and thus pose a significant burden to public health. During alphaviral replication, significant quantities of viral genomic RNAs that lack the canonical alphaviral 5’ cap structure are produced and packaged into viral particles, despite the fact that these noncapped genomes cannot be translated and are essentially noninfectious. The production and packaging of the noncapped genomes has been found to be true for infections across multiple vertebrate and invertebrate cell lines and alphavirus species, although the proportion of ncgRNA produced differs. Despite …

Two-Year Responses Of Heart Rate And Heart Rate Variability To First Occupational Lead Exposure, Yuling Yu, Lutgarde Thijs, Cai-Guo Yu, Wenyi Yang, Jesus D. Melgarejo, Dongmei Wei, Fangfei Wei, Tim S. Nawrot, Peter Verhamme, Harry Roels

School of Medicine Publications

Because of the falling lead exposure, the literature relating autonomous nervous function to blood lead (BL) has limited relevance. In the longitudinal Study for Promotion of Health in Recycling Lead (URL: https://www.clinicaltrials.gov; Unique identifier: NCT02243904), we recorded the 2-year responses of heart rate (HR), HR variability (HRV; Cardiax, International Medical Equipment Developing, Budapest, Hungary), and median nerve conduction velocity (Brevio, NeuMed, West Trenton, NJ), a routine test in occupational medicine, to first lead exposure in 195 newly hired workers (91.3% men; mean age, 27.8 years). High- and low-frequency HRV power and orthostatic HRV responses were derived from 5-minute ECGs …

Investigation Of Alpl Variant States And Clinical Outcomes: An Analysis Of Adults And Adolescents With Hypophosphatasia Treated With Asfotase Alfa., Priya S. Kishnani, Guillermo Del Angel, Shanggen Zhou, Eric T. Rush

Manuscripts, Articles, Book Chapters and Other Papers

Background: Hypophosphatasia (HPP), a rare metabolic disease, can be inherited in an autosomal recessive (biallelic) or an autosomal dominant (monoallelic) manner. Most of the severe, early-onset, frequently lethal HPP in infants is acquired through recessive inheritance; less severe, later-onset, typically nonlethal HPP phenotypes are acquired through either dominant or recessive inheritance. HPP's variable clinical presentation arises from >400 identified ALPL pathogenic variants with likely variable penetrance, especially with autosomal dominant inheritance. This post hoc analysis investigated the relationship between ALPL variant state (biallelic and monoallelic) and clinical outcomes with asfotase alfa in HPP.

Methods: Data were pooled from two phase …

The Impact Of Prolonged Estrogen Deficiency On Cardiac Hypertrophy Following Chronic Sympathetic Stimulation, Isabelle Krueger

Undergraduate Honors Theses

Cardiovascular disease (CVD) is the leading cause of death for both men and women in developed countries. Compared to age-matched males, premenopausal women experience lower rates of CVD but this increases after menopause. A central feature in CVD is changes in sympathetic regulation leading to pathological changes such as cardiac hypertrophy characterized by changes in cardiomyocyte size due to overcompensation of the muscle following injury. The goal of this research is to study the effect of prolonged estrogen loss on cardiac hypertrophy following chronic sympathetic stimulation. Female mice were ovariectomized at 10 weeks of age and treated with Isoproterenol to …
