Background: The blood-brain barrier (BBB) is responsible for maintaining brain homeostasis and ultimately proper neuronal function. Disruption of the BBB, leading to increased BBB permeability, has been reported in several neurodegenerative diseases, including Alzheimer’s disease (AD) and traumatic brain injury (TBI). Lipoxins (LXs) are a class of arachidonate-derived eicosanoids, which are a class of specialized pro-resolving lipid mediators (SPMs). SPMs are known to inhibit immune response through inhibition of cellular infiltration, downregulation of pro-inflammatory mediators and upregulation of anti-inflammatory mediators. Hence, LXs are recognized as “breaking signals” in the inflammatory process. One form of LXs, Lipoxin A4 (LXA4) …

Evaluation Of An End-To-End Radiotherapy Treatment Planning Pipeline For Prostate Cancer, Mohammad Daniel El Basha, Court Laurence, Carlos Eduardo Cardenas, Julianne Pollard-Larkin, Steven Frank, David T. Fuentes, Falk Poenisch, Zhiqian H. Yu

Dissertations & Theses (Open Access)

Radiation treatment planning is a crucial and time-intensive process in radiation therapy. This planning involves carefully designing a treatment regimen tailored to a patient’s specific condition, including the type, location, and size of the tumor with reference to surrounding healthy tissues. For prostate cancer, this tumor may be either local, locally advanced with extracapsular involvement, or extend into the pelvic lymph node chain. Automating essential parts of this process would allow for the rapid development of effective treatment plans and better plan optimization to enhance tumor control for better outcomes.

The first objective of this work, to automate the treatment …


Cord Blood-Derived Invariant Natural Killer T Cells As A Platform For Allogeneic Chimeric Antigen Receptor Cell Therapy, Maison Grefe May 2024

Cord Blood-Derived Invariant Natural Killer T Cells As A Platform For Allogeneic Chimeric Antigen Receptor Cell Therapy, Maison Grefe

Dissertations & Theses (Open Access)

Chimeric antigen receptor (CAR) T cells have revolutionized the treatment of hematopoietic malignancies achieving >50% complete response rates in numerous refractory/relapsed B cell malignancies. However, there are challenges that hinder CAR-T efficacy and bar the broader use of this therapy in patients. One approach to address these challenges is to create a safe allogeneic CAR cell product by using cells that do not cause graft versus host disease (GvHD). Invariant natural killer T (iNKT) cells are an ideal candidate as they are restricted to the monomorphic CD1d protein in contrast to HLA restricted αβ-T cells and therefore are safe in …


Photon Irradation And Cisplatin Enrich Cancer Stem Cells In Ovarian Cancer, Ashley Antonissen May 2024

Photon Irradation And Cisplatin Enrich Cancer Stem Cells In Ovarian Cancer, Ashley Antonissen

Electronic Theses, Projects, and Dissertations

High Grade Serous Ovarian Cancer (HGSOC) has a 5-year survival rate of less than 50%. Ovarian cancer is one of the deadliest gynecological diseases and the 7th most common female cancer worldwide. Ovarian cancer patients generally have a poor prognosis despite the relatively successful treatments. When conventional cancer treatments, such as cisplatin chemotherapy and photon irradiation, are administered, residual cancer stem-like cells (CSCs) can survive, leading to CSC enrichment. CSCs are a small population of cancer cells that exhibit stem-like characteristics: quiescence (slowing of the cell cycle), differentiation, proliferation, and self-renewal to regenerate new CSCs. We hypothesized that providing cancer …

Perinatal Buprenorphine Effects On Offspring Growth, Opioid Withdrawal, And Brain Morphology In Rats, Parker Barnes May 2024

Perinatal Buprenorphine Effects On Offspring Growth, Opioid Withdrawal, And Brain Morphology In Rats, Parker Barnes

Electronic Theses and Dissertations

Opioid use disorder (OUD) impacts 5.6 million people in the US. Buprenorphine (BUP) is a commonly prescribed opioid medication used to treat OUD, including in pregnant women. However, opioid use during pregnancy is associated with poorer infant outcomes including reduced fetal growth, neurodevelopmental deficits, and neonatal opioid withdrawal syndrome (NOWS). Recent clinical data suggests that providing mothers with a lower dose of BUP may result in fewer negative outcomes in infants. Here, a preclinical rodent model of low-dose perinatal BUP exposure was used to study offspring health outcomes in the neonate, juvenile, and adolescent offspring. Dams were given clinically relevant …


Examining The Effects Of Menstrual Cycle Phase And Hormonal Contraceptive Use On Women's Sleep, Charles Ethan Coombs May 2024

Examining The Effects Of Menstrual Cycle Phase And Hormonal Contraceptive Use On Women's Sleep, Charles Ethan Coombs

Psychological Science Undergraduate Honors Theses

Women overrepresent men for sub-optimal sleep, a consequence of hormone fluctuation in the menstrual cycle affecting sleep regulatory pathways. While research has examined the prevalence of sub-optimal sleep through cycle phases, little research has examined how hormonal contraceptives (HC’s) could similarly affect women’s sleep, while also neglecting to utilize subjective sleep measures. In this study, we examine subjective sleep quality among naturally cycling (NC) women, women using different HC types, and between active and inactive phase pill users by subjecting 463 women to a subjective sleep battery. We hypothesized that HC users would report more sub-optimal sleep than NC women. …


Molecular Mechanisms Of Opioid Use Disorder In Human Brain Models, Emily Mendez May 2024

Molecular Mechanisms Of Opioid Use Disorder In Human Brain Models, Emily Mendez

Dissertations & Theses (Open Access)

Opioid use disorder (OUD) is a national and global public health crisis with no end in sight. While studies from animal models hint at widespread epigenetic and transcriptomic alterations of opioid drugs, the molecular consequences of long-term exposure to opioid drugs in human brain is still unclear, and human-centered translational models are necessary to discern the human cell type-specific effects of OUD.

Using postmortem brain Brodmann area 9 (BA9) from the UTHealth Brain Collection for Research on Psychiatric Disorders, I identified angiogenic gene networks perturbed in the RNA and protein of OUD subjects, as well as downregulation of many neuron-correlated …

The Role Of Myocardin And Its Effector Proteins In Tgf-Β Induced Cytoskeletal Remodeling Of Ipf Fibroblasts, Khadijat Abolore Olawuyi May 2024

The Role Of Myocardin And Its Effector Proteins In Tgf-Β Induced Cytoskeletal Remodeling Of Ipf Fibroblasts, Khadijat Abolore Olawuyi

Biotechnology Theses

Idiopathic pulmonary fibrosis (IPF) is characterized by thickening and stiffness around the air sacs. Approved treatments like nintedanib and pirfenidone slow disease progression in IPF and often have tolerability issues. More research is needed to fully grasp the mechanisms behind abnormal cytoskeletal changes in lung cells, notably fibroblasts and epithelial cells, and their role in fibrosis progression. Previous studies suggest that myocardin expression and function, traditionally limited to smooth/cardiac development in physiology, become active in pathophysiological conditions like pleural fibrosis. Myocardin's role in liver and kidney fibrosis is known, but its involvement in IPF is unclear. To get more insights, …

Syndrome Or Symptoms? Assessing Cothymia, Neuroticism And Lifetime Comorbidity In A Sample Of Psychiatric Patients, Fiammetta Iannuzzo, Fabiana Fiasca, Antonella Mattei, Carmela Mento, Maria Catena Silvestri, Fabrizio Turiaco, Rocco Antonio Zoccali, Maria Rosaria Anna Muscatello, Antonio Bruno

Journal of Mind and Medical Sciences

Background. Cross-sectional and longitudinal psychiatric comorbidity rates could represent a syndromic process rather than the co-occurrence of different disorders. ‘Cothymia’, the concomitant presence of depression and anxiety symptoms, and the ‘neuroticism’ dimension have been proposed as candidate vulnerability factors for psychiatric disorders trajectories. Based on this background, the present research was aimed at assessing the role of cothymia and neuroticism as syndromic processes in lifetime psychiatric disorders, and examining homotypic or heterotypic trends in the diagnostic continuum of comorbid mental disorders. Materials and methods. Data collection was carried out retrospectively through the consultation of medical records at the Psychiatry Unit …

Genetic And Serological Markers In Colorectal Cancer Surgery, Adrian Silaghi, Vlad Denis Constantin, Dragos Serban, Dragos Epistatu, Ioana Paunica, Daniela Gabriela Bălan, Laura Florentina Rebegea

Journal of Mind and Medical Sciences

Colon cancer is relatively asymptomatic in the early stages, the manifestations appearing and intensifying with the evolution of the disease, especially when associated with local and/or systemic complications. In such cases, surgical interventions are often emergency and involve more extensive operations (on metabolically and immune-stressed organisms), so that an early diagnosis (endoscopy, tumor markers, etc.) remains not only desirable but even a priority, especially in predisposed patients (genetic factors, lifestyle, etc.). As a consequence, the involvement of tumor markers in colon neoplasms has become more and more investigated in recent times. This review investigates the roles of serological and genetic …


Selective Serotonin Reuptake Inhibitors And Pharmacological Resetting Of The Mind, Ion G. Motofei, David L. Rowland Apr 2024

Selective Serotonin Reuptake Inhibitors And Pharmacological Resetting Of The Mind, Ion G. Motofei, David L. Rowland

Journal of Mind and Medical Sciences

Mental activity is capable of processing analytical data (mathematics, physics, socio-political science, philosophy, etc.) similar to computer software. At the same time, mental activity largely depends on the brain, which works like a hard component of a computer. While the computer stores data on a physical medium, mental activity and data are supported by physiological mechanisms that are constantly operating (both in wakefulness and sleep). For this reason, the lack of brain oxygenation even for short periods of time (5-10 minutes) causes the loss of all data, including the disappearance of the individual's existence as a mental entity. This means …

Suspected Thiamine Deficiency Secondary To Chronic Gastrointestinal Illness: A Case Report, Abigail L. Meckley, Natalie Lagattuta, Elise Gonzalez, Chamonix Kinimaka, Jessica El-Bahri

HCA Healthcare Journal of Medicine

Introduction

Thiamine deficiency, also known as beriberi, is a nutritional disorder caused by a lack of thiamine (vitamin B1) in the diet. It can occur in 2 forms: dry beriberi, which affects the nervous system, and wet beriberi, which affects the cardiovascular system. Gastrointestinal beriberi is a subtype that affects the digestive system and can lead to multisystem involvement. In the United States (US), thiamine deficiency often arises from chronic malnutrition secondary to alcoholism, known as Wernicke-Korsakoff Syndrome.

Actinic Granuloma Complicated By Secondary Syphilis: A Case Report, Kevin H. Nguyen, Christopher M. Wong, Ethan Q. Nguyen Apr 2024

Actinic Granuloma Complicated By Secondary Syphilis: A Case Report, Kevin H. Nguyen, Christopher M. Wong, Ethan Q. Nguyen

HCA Healthcare Journal of Medicine

Introduction

Actinic granuloma (AG) is a rare skin eruption thought to result from a sun-induced inflammatory response attracting giant cells, which are large, multinucleated, and inflammatory, to form granulomas and degrade surrounding elastic material. Clinically, lesions begin on sun-exposed skin as pink papules and nodules that coalesce into demarcated annular plaques with a hypopigmented center. Histologically, actinic elastosis surrounds the outer annulus ring, with histiocytes and giant cells within the raised border, and the innermost central zone is filled with minimal to absent elastic fibers.

Case Presentation

We present a middle-aged female with a pruritic eruption of diffuse erythematous macules …

Journal Articles

Internalization from the cell membrane and endosomal trafficking of receptor tyrosine kinases (RTKs) are important regulators of signaling in normal cells that can frequently be disrupted in cancer. The adrenal tumor pheochromocytoma (PCC) can be caused by activating mutations of the rearranged during transfection (RET) receptor tyrosine kinase, or inactivation of TMEM127, a transmembrane tumor suppressor implicated in trafficking of endosomal cargos. However, the role of aberrant receptor trafficking in PCC is not well understood. Here, we show that loss of TMEM127 causes wildtype RET protein accumulation on the cell surface, where increased receptor density facilitates constitutive ligand-independent activity and …

Type VI CRISPR-Cas systems are among the few CRISPR varieties that target exclusively RNA. The CRISPR RNA–guided, sequence-specific binding of target RNAs, such as phage transcripts, activates the type VI effector, Cas13. Once activated, Cas13 causes collateral RNA cleavage, which induces bacterial cell dormancy, thus protecting the host population from the phage spread. We show here that the principal form of collateral RNA degradation elicited by Leptotrichia shahii Cas13a expressed in Escherichia coli cells is the cleavage of anticodons in a subset of transfer RNAs (tRNAs) with uridine-rich anticodons. This tRNA cleavage is accompanied by inhibition of protein synthesis, thus …
