Describing Shen & Shen Ming Via A Hybrid Quantum Computational Model, Alex M. Cullen, Johnny Lemau May 2024

Describing Shen & Shen Ming Via A Hybrid Quantum Computational Model, Alex M. Cullen, Johnny Lemau

Student Research Symposium

Definitions for Traditional Chinese Medicine (TCM) terminology within the context of quantum biology (QB) have recently been proposed. These definitions aim to elucidate concepts such as qi meridians in TCM. Our study presents a hypothesis that seeks to provide an operational definition for Spirit (Shen) and Bright Spirit (Shen Ming) in TCM via a scoping review. We propose that Shen represents physical, phenomenological proto-consciousness/consciousness in the forms of computation, such as singular particles/bits/qubits, computers, organisms, or computational strategies, whereas Shen Ming may refer to emergent, quasi-physical meta-proto-consciousness/consciousness formed by coherent relationships of multiple orchestrated/integrated units of computation; manifesting itself as …

Predicting Stage Progression In Binet Stage A Chronic Lymphocytic Leukemia, Salem H. Alshemmari, Mazyad Almazyad, Ahmed Alsarraf, Anita Kunhikrishnan, Asha M. Isaac, Andy Kaempf

Hematology/Oncology and Stem Cell Therapy

Introduction: the variable clinical course of chronic lymphocytic leukemia (CLL) and the lack of consensus on follow-up and treatment strategies have necessitated a prognostic model for identifying high-risk patients at the time of diagnosis. Methods: this study involved a retrospective analysis of demographic and clinical characteristics of 212 patients diagnosed with Binet stage A CLL and thus eligible for risk stratification by both the International Prognostic Score for Early-stage CLL (IPS-E) and the alternative IPS-E (AIPS-E). We evaluated the applicability of these prognostic indices in our young, Middle Eastern cohort (median age 59 at diagnosis). Results: during a study period …


Understanding The Expression And Role Of Pros-1 In The Male Gonad Of C. Elegans, Jack Bozik Apr 2023

Understanding The Expression And Role Of Pros-1 In The Male Gonad Of C. Elegans, Jack Bozik

Undergraduate Theses

The gene pros-1 is a transcription factor that is highly expressed within neuronal sheath cells, glial cells, and excretory canal cells. pros-1 plays a role in cell determination of those cell types in the nematode C. elegans, which promotes organismal development. But the degree to which pros-1 presence is important is still not fully understood, because there are many genes involved in development that when mutated or damaged can result in unexpected phenotypes or even total loss of function to a certain developmental mechanism. What makes pros-1 valuable to research is that it is a functional homologue to a …


Warm Land Surface Temperatures And Eastern Asian Homo, Robert Patalano, Hong Yang Jan 2023

Warm Land Surface Temperatures And Eastern Asian Homo, Robert Patalano, Hong Yang

Biological and Biomedical Sciences Department Faculty Journal Articles

Climate change and hominin evolution are inextricably linked. Pleistocene climate variability, for example, is thought to have had major influences on hominin morphology, brain size, and diversity. However, clear cause-and-effect relationships between specific climatic events and major evolutionary occurrences are difficult to establish due to temporal and spatial gaps in paleoclimatic, paleoenvironmental, and archaeological records. A new branched GDGT paleotemperature record from the Lantian Basin of Central China (Lu et al., 2022), a location known for the earliest hominin presence in East Asia, illustrates warm land surface temperatures over a two-million-year period between 2.6 and 0.6 Ma, a critical time …

Proposing An Rna Interference (Rnai)-Based Treatment For Human Immunodeficiency Virus (Hiv) By Analyzing The Post-Transcriptional Gene Targeting Of Sars-Cov-2, Hepatitis C Virus, And A549 Lung Cancer Cells, Arjun Jagdeesh

Undergraduate Research Posters

Human Immunodeficiency Virus (HIV) is a retrovirus that infects CD4+ T cell lymphocytes in humans, leading to the development of Acquired Immunodeficiency Syndrome (AIDS) if left untreated. While current treatment methods, including antiretroviral combination treatments, effectively limit HIV replication, HIV can evade these treatments due to its high mutation rate. Long-term antiretroviral treatment can also be toxic to patients, meaning patients would benefit from a new mechanism of HIV treatment. RNA interference (RNAi) is an antiviral pathway found in mammals, plants, and insects that involves a small-interfering RNA that is incorporated into a protein complex called the RNA-induced Silencing Complex …

Faculty Mentor: Dr. David Baier, Biology

XROMM methods "re-animate" 3D skeletal motion of living animals by aligning digital bone models to X-ray videos. Surgically implanted markers permit automatic alignment of bone models if three or more markers are used. However, one of our specimens only had two markers implanted. These bones could be automatically positioned and partially oriented using the two markers, but then required manual alignment to the X-ray images to orient about the axis passing between the two markers. Here, we validated the method by digitally removing a marker from a …

Using techniques our lab has learned using these stem cell models have prepared us to examine cell communication in mutated neurons. We will …


Functional Analysis Of Stn1 Winged-Helix (Wh) Domains, Anna Bazell Apr 2022

Functional Analysis Of Stn1 Winged-Helix (Wh) Domains, Anna Bazell

Senior Theses

CST (CTC1-STN1-TEN1) is a heterotrimeric RPA-like protein complex that preferentially binds to single-stranded DNA (ssDNA). CST is conserved from yeast to humans and has been found to play a role in telomere maintenance, DNA replication, and DNA repair. Mutations in CST, specifically in the subunits of CTC1 and STN1, have been implicated in the development of the genetic diseases Coats plus and dyskeratosis congenita. Despite the known functions of CST, the mechanistic relationship between its structure and function has yet to be characterized, particularly with respect to its protein-protein interactions and DNA binding. An X-ray crystallography structure of CST revealed …

Undergraduate Research Posters

Background: Opioids are a class of drugs that are utilized in clinical settings to alleviate acute and chronic pain, but can often lead to development of tolerance, addiction and overdose following prolonged usage. Opioids such as morphine function by activating endogenous µ opioid receptors, which are located in various tissues throughout the body. Astrocyte Elevated Gene-1 (AEG-1) is a multifunctional protein that regulates inflammation, myeloid cell activity and lipid metabolism. Studies have shown interactions and overlaps in cellular signaling between the inflammatory/immune responses and the endogenous opioid system which could suggest a role for AEG-1 in opioids effects. Our goal …

Black And White Health Disparities: Racial Bias In American Healthcare, Yasmeen Almomani Jul 2021

Black And White Health Disparities: Racial Bias In American Healthcare, Yasmeen Almomani

Bridges: An Undergraduate Journal of Contemporary Connections

This paper explores the historical implications of race in American society that have led to implicit racism in the healthcare system. Racial bias in healthcare against Black people is a factor in the health disparities between Black and white people in America, such as the gap in life expectancy, infant death, and maternal mortality. Black people are more likely to report racial discrimination from healthcare providers, which is a reason for the decreased quality of care received. The past justifications of slavery, the Tuskegee syphilis study, and the medical experimentations on Black women are horrifying but were considered acceptable in …

Harbor seals frequently strand along the northeast coast of the United States due to injury, illness, disease, and human interaction. In Maine, a non-profit organization, Marine Mammals of Maine (MMoME), is federally authorized to respond to these stranded animals and provide short-and long-term rehabilitation, with the ultimate aim to release the seals back into the wild. I investigated the role of multiple potential measures of marine mammal health that are evaluated at admit in determining rehabilitation success of dependent and weaned harbor seal pups from 2016 to 2019. The variables assessed were the day of the year the patients were …


Mediation Of The Uncoupled Enos Pathway Following Oxidative Stress Using Tetrahydrobiopterin And Nitric Oxide Donor Drugs To Restore Tetrahydrobiopterin Concentration, Brianna Munnich Apr 2021

Mediation Of The Uncoupled Enos Pathway Following Oxidative Stress Using Tetrahydrobiopterin And Nitric Oxide Donor Drugs To Restore Tetrahydrobiopterin Concentration, Brianna Munnich

Scholar Week 2016 - present

Presentation Location: Warming House, Olivet Nazarene University

Abstract

The eNOS pathway, found in the endothelium of blood vessels, is a key regulator of nitric oxide levels in the circulatory system. The pathway is controlled through several positive and negative feedback loops [2]. The cofactor tetrahydrobiopterin (BH4) is a major control point in this pathway and under conditions of stress can be reduced into the dihydrobiopterin (BH2) [2,6,7,8,9]. When the reduced form is predominant, the pathway produces reactive oxygen species (ROS) rather than nitric oxide, causing stress and damage to the vessels [6,7,8,9]. In this study, different treatments were studied …

Examining The Mechanistic Roles Of Integrin Alpha-6 In Cancer Metastasis., Chase T. Clark Mar 2021

Examining The Mechanistic Roles Of Integrin Alpha-6 In Cancer Metastasis., Chase T. Clark

Honors College Theses

Metastasis- the spread of cancer cells from the primary tumor to the surrounding tissues- is responsible for 90% of cancer deaths. Integrin alpha-6 (ITGA6) is a specific transmembrane cell surface protein that functions in cell surface adhesion and signaling. ITGA6 is upregulated in many types of cancers and promotes the migration and invasion of cancer cells to surrounding tissues. It is my objective to determine the mechanism through which ITGA6 facilitates the migration of cancer cells through the extracellular matrix (ECM). These experiments helped to establish the role of ITGA6 in tumor development and provide focus for possible chemotherapeutic treatment. …

A Look At Gene Control: Tracking The Ccnd1 Gene, Bryan Anders Jan 2020

A Look At Gene Control: Tracking The Ccnd1 Gene, Bryan Anders

Mahurin Honors College Capstone Experience/Thesis Projects

Cancer occurs when the cell does not properly control its own cell cycle. It then replicates in an out of control fashion leading to the death of various organs and then the demise of the organism as a whole. As it seems to have always been a problem for cell-based life, certain safeguards against cancer have been evolved over time. One such method comes in the form of prevention via cyclin proteins, which are encoded from cyclin genes. The gene that is the focus of this research is the CCND1, or cyclin D1, gene that controls the progression through various …


Neuroanatomy Of The Blackspotted Rockskipper, Entomacrodus Striatus, Pooja Dayal Jan 2020

Neuroanatomy Of The Blackspotted Rockskipper, Entomacrodus Striatus, Pooja Dayal

Williams Honors College, Honors Research Projects

Here I characterized the central neuroanatomy of the Blackspotted Rockskipper, Entomacrodus striatus, native to French Polynesia. The neuroanatomy of E. striatus has not been studied prior to this paper. I used several histology and antibody staining techniques to accomplish this, including Crystal Violet, immunohistochemistry, immunofluorescence, and Bielschowsky’s Silver Nitrate staining. This paper describes the most successful techniques used, identifies major structures in the species’ neuroanatomy, and also explains why studying E. striatus is important in the future of vertebrate research.

Study Of Blood Viscosity With Added Sodium Nitrate And Temperature Variance: A Potential Therapy To Regulate Blood Flow After Induced Hypothermia, Brianna Munnich

Pence-Boyce STEM Student Scholarship

The human body has natural systems for vasodilation which are fueled by nitric oxide production, but in cases of cardiac disfunction and stress nitric oxide can be inhibited. In this study, nitric oxide was studied as a mediator for the blood rush experienced from the warming after induced hypothermia. Nitric oxide (NO) was introduced through sodium nitrate, which was aimed to reduce the speed and turbulence of blood flow through interaction between NO and the active site of hemoglobin. A viscometer was used to examine the rate of blood flow, while the temperature was varied to simulate the conditions of …

Background: A rapid in-house TM4 mycobacteriophage-based assay, to identify multidrug resistance against various anti-tuberculosis drugs, using the fast-growing Mycobacterium smegmatis mc2 155 in a microtiter plate format was evaluated, based on phage viability assays. Methods: A variety of parameters were optimized before the study including the minimum incubation time for the drugs, phage and M. smegmatis mc2 155 to be in contact. An increase in phage numbers over 2 h was indicative that M. smegmatis mc2 155 is resistant to the drugs under investigation, however when phage numbers remained static, M. smegmatis mc2 155 found to …


Investigating The Role Of Free Radicals In Huntington's Disease Using Drosophila Melanogaster, Jennifer Libov Mar 2019

Investigating The Role Of Free Radicals In Huntington's Disease Using Drosophila Melanogaster, Jennifer Libov

Honors Theses

During normal cell metabolism, reactive oxygen species (ROS) are produced as a byproduct of oxidative phosphorylation. ROS are utilized in the cell as a signaling molecule and can be maintained at healthy levels by cellular antioxidants. However, when the cell experiences oxidative stress due to environmental or genetic conditions, levels of ROS can exceed healthy levels and inhibit necessary life functions by damaging biomolecules and cellular structures. This loss of function can lead to physiological decline and neurodegeneration, such as in diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and, potentially, Huntington’s disease. The following experiments use the model genetic organism …


Student-Faculty Collaborative Research Grant Report, Megan Bestwick Feb 2019

Student-Faculty Collaborative Research Grant Report, Megan Bestwick

Post-Grant Reports

Mitochondria are essential organelles in most eukaryotic cells because of their role in metabolism and the production of ATP by the oxidative phosphorylation (OXPHOS) pathway, as well as other key cellular processes. Metal cofactors, such as copper (Cu) and iron (Fe), are incorporated into OXPHOS protein complexes of yeast located within the inner membrane of the mitochondria. Misincorporation or modulation of these available metals in mitochondrial enzymes leads to the production of reactive oxygen species (ROS). ROS are reactive molecules containing oxygen such as peroxides, superoxide, and hydroxyl radicals. Yeast are a good model for studying aging and the effect …

Role Of Dyslipidemia On Lipid Metabolism In Maintenance Hemodialysis Patients, Eno Latifi Jan 2019

Role Of Dyslipidemia On Lipid Metabolism In Maintenance Hemodialysis Patients, Eno Latifi

Wayne State University Dissertations

Maintenance hemodialysis (MHD) patients experience various abnormalities such as systemic inflammation (SI), oxidative stress (OS), and dyslipidemia (D). Defined as an imbalance of plasma lipids, lipoproteins, and lipid metabolism enzymes, D has been associated with a rise in morbidity and mortality within ESRD patients due to cardiovascular disease (CVD). However, the contribution of each of these parameters to D is poorly understood; moreover, the impact of the following parameters on dyslipidemia in different ethnicities is unknown. Hence, the objective of this study was to characterize D in a multi-ethnic cohort of ESRD patients. We hypothesized that the degree of dyslipidemia …

This article describes two techniques for biopsy of the bovine mammary gland (MG). Three healthy Holstein dairy cows were the subjects. Before biopsies, cows were milked and subsequently restrained in a cattle chute. An analgesic (flunixin meglumine, 1.1 to 2.2 mg/kg of body weight) was administered via jugular intravenous [IV] injection 15-20 min prior to biopsy. For standing sedation, xylazine hydrochloride (0.01-0.05 mg/kg of body weight) was injected via the coccygeal vessels 5-10 min before the …


The Effect Of Kalanchoe Pinnata In Astrocitome Metastasis, Jorge Rosa Jun 2018

The Effect Of Kalanchoe Pinnata In Astrocitome Metastasis, Jorge Rosa

The International Student Science Fair 2018

Astrocytomas, from cell line 1321N1,are cancerous astrocytes. These are a type of glial cell in the brain which is responsible for maintaining synaptic contact and the signaling capacities among neurons. They also represent a fundamental element in controlling blood flow and defining brain micro structure. Due to the fact that this variant is cancerous, a condition commonly described as an abnormal cell cycle and uncontrolled reproduction of cells, they have the ability to metastasize.

In the metastatic process of cancer cells the initial phase is know as tumor invasion. This stage consists mainly of the cells migrating away from the …
