Meningomyelocele (also known as spina bifida) is considered to be a genetically complex disease resulting from a failure of the neural tube to close. Individuals with meningomyelocele display neuromotor disability and frequent hydrocephalus, requiring ventricular shunting. A few genes have been proposed to contribute to disease susceptibility, but beyond that it remains unexplained1. We postulated that de novo mutations under purifying selection contribute to the risk of developing meningomyelocele2. Here we recruited a cohort of 851 meningomyelocele trios who required shunting at birth and 732 control trios, and found that de novo likely gene disruption or …

Functional Mocktails, Amber Barrer

Electronic Theses, Projects, and Dissertations

Background and Aims: Mocktails are alcohol-free beverages that emulate alcohol-containing cocktails. Americans are increasingly seeking these non-alcoholic beverage alternatives. As mocktails have increased in popularity, so have anecdotal health claims. Research has shown that the consumption of teas, herbs, roots, and juices provide health benefits. However, these have not been studied as a mocktail beverage. Functional mocktails may provide various health benefits due to their antioxidant properties, serving as an enjoyable alternative to alcoholic beverages.

Methods: A recipe book of 20 functional mocktails were created. The recipe book includes referenced research on the health benefits, antioxidative properties, recommended dosing, and …


Micronutrient Deficiencies In Celiac Disease: Systematic Review, Natalie A. Martinez May 2025

Micronutrient Deficiencies In Celiac Disease: Systematic Review, Natalie A. Martinez

Electronic Theses, Projects, and Dissertations

Celiac disease (CD) is a chronic autoimmune disease triggered by the ingestion of gluten in genetically susceptible individuals, leading to villous atrophy, nutrient malabsorption, and a range of systemic complications. Although adherence to a strict gluten-free diet (GFD) remains the only effective treatment, growing evidence suggests that the GFD alone may be insufficient in meeting the long-term nutritional and psychosocial needs of adults with CD. This systematic review evaluates the prevalence and persistence of micronutrient deficiencies—including iron, calcium, vitamin D, folate, vitamin B12, magnesium, and zinc—in adult CD populations following a GFD. It also examines the psychological burden associated with …

Genome-wide association studies (GWASs) in Alzheimer disease (AD) have uncovered over 70 loci significantly associated with AD risk, but identifying the true causal gene(s) at these loci requires systematic functional validation that is rarely performed due to limitations of time and cost. Here, we integrate transcriptome-wide association study (TWAS) with colocalization analysis, fine-mapping, and additional annotation of AD GWAS variants to identify 123 genes at known and suggestive AD risk loci. A comparison with human AD brain transcriptome data confirmed that many of these candidate genes are dysregulated in human AD and correlate with neuropathology. We then tested all available …

Leptomeningeal metastases are the major source of morbidity and mortality for patients with medulloblastoma. The biology of the leptomeningeal metastases and the local tumour microenvironment are poorly characterized. Here we show that metastasis-associated meningeal fibroblasts (MB-MAFs) are transcriptionally distinct and signal extensively to tumour cells and the tumour microenvironment. Metastatic cells secrete platelet-derived growth factor (PDGF) ligands into the local microenvironment to chemotactically recruit meningeal fibroblasts. Meningeal fibroblasts are reprogrammed to become MB-MAFs, expressing distinct transcriptomes and secretomes, including bone morphogenetic proteins. Active bone morphogenetic protein signalling and co-implantation of tumour cells with MB-MAFs enhances the colonization of the leptomeninges …

Introduction: Tau is essential for amyloid beta (Aβ)-induced synaptic and cognitive deficits in Alzheimer's disease (AD), making its downregulation a therapeutic target. Cerebral amyloid angiopathy (CAA), a major vascular contributor to cognitive decline, affects over 90% of patients with AD. This study explores the impact of tau downregulation on CAA pathogenesis.

Methods: We crossed the Familial Danish Dementia mouse model (Tg-FDD), which develops vascular amyloid, with tau-null (mTau-/-) mice to generate a CAA model lacking endogenous tau (Tg-FDD/mTau-/-). Behavioral, electrophysiological, histological, and transcriptomic analyses were performed.

Results: Tau depletion ameliorated motor and synaptic impairments, reduced vascular amyloid deposition, and prevented …

Anteroposterior elongation of the vertebrate body plan is driven by convergence and extension (C&E) gastrulation movements in both the mesoderm and neuroectoderm, but how or whether molecular regulation of C&E differs between tissues remains an open question. Using a zebrafish explant model of anteroposterior axis extension, we show that C&E of the neuroectoderm and mesoderm can be uncoupled ex vivo, and that morphogenesis of individual tissues results from distinct morphogen signaling dynamics. Using precise temporal manipulation of BMP and Nodal signaling, we identify a critical developmental window during which high or low BMP/Nodal ratios induce neuroectoderm- or mesoderm-driven C&E, respectively. …

Metabolism is fundamental to organism physiology and pathology. From the intricate network of metabolic reactions, diverse chemical molecules, collectively termed metabolites, are produced. In multicellular organisms, metabolite communication between different tissues is vital for maintaining homeostasis and adaptation. However, the molecular mechanisms mediating these metabolite communications remain poorly understood. Here, we focus on nucleosides and nucleotides, essential metabolites involved in multiple cellular processes, and report the pivotal role of the SLC29A family of transporters in mediating nucleoside coordination between the soma and the germline. Through genetic analysis, we discovered that two Caenorhabditis elegans homologs of SLC29A transporters, Equilibrative Nucleoside Transporter …

Efficacy Of Stem Cell Therapy Versus Standard Drug Therapy In Adults With Heart Failure, Evie Reynolds May 2025

Efficacy Of Stem Cell Therapy Versus Standard Drug Therapy In Adults With Heart Failure, Evie Reynolds

Physician Assistant Scholarly Project Papers

Myocardial infarction (MI) or other damage to the heart tissue may result in ischemia, and because cardiomyocytes have limited regenerative capacity, this often leads to the development of heart failure (HF). Typical symptoms of HF include dyspnea, edema, cough, fatigue, and chest pain, which arises from fluid overload and congestion. Current medical treatments focus on alleviating these symptoms through loop diuretics, which reduce fluid accumulation but do not treat the underlying ischemic damage. Recent studies have shifted focus towards stem cell therapy, which have shown potential to differentiate into cardiomyocytes and regenerate ischemic heart tissue. A comprehensive search of databases …

Advanced maternal age (AMA) is defined as a pregnancy in a woman older than 35 years of age. AMA increases the risk for both maternal and neonatal complications, including miscarriage and stillbirth. AMA has also been linked to neurodevelopmental and neuropsychiatric disorders in the offspring. Recent studies have found that age-associated compositional shifts in the gut microbiota contribute to altered microbial metabolism and enhanced inflammation in the host. We investigated the specific contribution of the maternal microbiome on pregnancy outcomes and offspring behavior by recolonizing young female mice with aged female microbiome prior to pregnancy. We discovered that pre-pregnancy colonization …

Additionally, we highlight the potential of targeting CPR to study mechanisms of lung injury and leverage gene-editing technologies …


Venlafaxine Exposure In Pregnancy And Its Association With Pre-Eclampsia Development, Jhanvi Patel May 2025

Venlafaxine Exposure In Pregnancy And Its Association With Pre-Eclampsia Development, Jhanvi Patel

Posters

Venlafaxine, a serotonin-norepinephrine reuptake inhibitor (SNRI), is widely used to manage depression and anxiety, including in pregnant women. However, its known hypertensive side effects raise concerns about a potential link to pre-eclampsia, a serious pregnancy complication characterized by new-onset hypertension and proteinuria. Pregnant women with psychiatric disorders already have an increased risk of hypertensive disorders, and while untreated depression can lead to adverse outcomes such as preterm birth and fetal cortisol elevation, the safety of venlafaxine remains uncertain. Current research lacks wellcontrolled studies assessing its association with hypertensive complications in pregnancy. This systematic review aims to evaluate whether venlafaxine use …


The Effect Of Antemortem Tooth Loss On Craniofacial Shape In Apes And Humans, Ashley R. Laster May 2025

The Effect Of Antemortem Tooth Loss On Craniofacial Shape In Apes And Humans, Ashley R. Laster

Biological Sciences Undergraduate Honors Theses

Antemortem tooth loss (AMTL) (i.e., defined as tooth loss occurring before death) is common among humans and many primates, and several studies have examined AMTL across various primate groups. Some research indicates that AMTL can influence masticatory function and diet; however, the effects of AMTL on craniofacial shape and biomechanics have not been extensively analyzed. We assessed craniofacial and mandibular shape in relation to AMTL, anticipating that individuals with at least one tooth lost antemortem would display significant differences in cranial and/or mandibular shape compared to those without AMTL. AMTL rates were evaluated in three primate species: wild-caught samples of …

Toxicity And Biodegradability Of Novel Boronium Vs Conventional Ammonium-Based Antimicrobial Compounds In Wastewater Treatment Systems, Noor Shalan May 2025

Toxicity And Biodegradability Of Novel Boronium Vs Conventional Ammonium-Based Antimicrobial Compounds In Wastewater Treatment Systems, Noor Shalan

Honors Theses

Quaternary ammonium compounds (QACs) are highly effective as disinfectants, herbicides, and pesticides; thus, overuse causes elevated levels of residual toxicity in domestic and industrial wastewater. QACs can be toxic to essential bacteria breaking down pollutants in wastewater treatment plants (WWTPs) and can remain untreated in effluent, harming the environment, and contributing to antibiotic resistance, posing risks to human health. Novel boronium-based antimicrobial compounds have demonstrated efficacy in eliminating bacteria, fungi, and viruses. If the boronium compounds exhibit lower residual toxicity, they could offer a promising alternative to QACs. Because these compounds are still in development, their potential toxicity to the …

Evaluation Of Avenanthramide-A As A Skin Penetration Enhancer: In Vitro And In Vivo Testing On Permeation Of Magnesium Ascorbyl Phosphate And Diclofenac Sodium From Topical Gels, Darshil Dhiren Shah

Selected Full-Text Dissertations 2020-

Topical and transdermal drug delivery are favored to deliver active pharmaceutical ingredients directly to the skin as an alternative to oral administration for systemic effects. In either case, the active molecules must cross the stratum corneum and epidermis to reach the site of action. The stratum corneum serves as a primary barrier limiting compounds from fully penetrating the skin. Therefore, it is necessary to add penetration enhancers to topical formulations to enhance drug delivery through the skin. Often, penetration enhancers are also irritant to the skin. Earlier research in our pharmaceutical laboratory showed that an addition of colloidal oatmeal, produced …
