Quantile Index Predictors Using R Package Hyper.Gam, Tingting Zhan, Misung Yi, Inna Chervoneva
Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers
MOTIVATION: Evaluation of single-cell protein expression from immunohistochemistry images is used increasingly in biomedical research. Many proteins are used solely for phenotyping cells in the tumor microenvironment. Other proteins with meaningfully quantitative expression levels provide so-called functional protein biomarkers. There is still a limited number of methods and software tools available for utilizing the entire distributions of single-cell expression levels.
RESULTS: We present the R package hyper.gam, providing a supervised learning framework for deriving biomarkers based on single-cell distribution quantiles. The single-cell data are first converted into sample quantile functions, which are then used as predictors in scalar-on-function regression models …

This study aimed to assess the correlation between RNA sequencing (RNA-seq) and immunohistochemistry (IHC) in detecting key cancer biomarkers across solid tumors, and then, to establish RNA-seq thresholds that accurately reflect clinical IHC classifications. Expression levels of nine biomarkers-ESR1, PGR, AR, MKI67, ERBB2, CD274, CDX2, KRT7, and KRT20-were analyzed in 365 formalin-fixed, paraffin-embedded samples from breast, lung, gastrointestinal, and other solid carcinomas. Correlations between RNA-seq data and IHC scores were determined using Spearman's correlation coefficients, with RNA-seq cut-offs established to distinguish positive from negative IHC scores. The results revealed strong correlations for most biomarkers, with coefficients ranging from 0.53 to …

Nuclear loss and cytoplasmic buildup of the RNA-binding protein TDP-43 is a hallmark of ALS and related disorders. While studies using artificial TDP-43 depletion in neurons have revealed changes in gene expression and splicing, their relevance to actual patients remained unclear. Induced pluripotent stem cell (iPSC)-derived neurons (iPSNs) from 180 individuals, including controls, C9orf72 ALS/FTD, and sporadic ALS (sALS) patients were used to generate and analyze ~32,500 qRT-PCR data points across 20 genes which identified variable, time-dependent signatures of TDP-43 loss of function in individual lines. Notably, the same changes were also seen in postmortem brain tissue from the same …

Idiopathic pulmonary fibrosis (IPF) is a progressive and lethal disease characterized by excessive extracellular matrix deposition. Current IPF therapies slow disease progression but do not stop or reverse it. The (myo)fibroblasts are thought to be the main cellular contributors to excessive extracellular matrix production in IPF. Here we show that fibrotic alveolar type II cells regulate production and crosslinking of extracellular matrix via the co-transcriptional activator YAP. YAP leads to increased expression of Lysl oxidase (LOX) and subsequent LOX-mediated crosslinking by fibrotic alveolar type II cells. Pharmacological YAP inhibition via verteporfin reverses fibrotic alveolar type II cell reprogramming and LOX …

Joint Kinematics And Kinetics During Vertical Jump Landings With Progressively Increasing External Loads, Darcie L. Yount
Dissertations
This study examined sagittal and frontal plane kinematics and kinetics during countermovement jump (CMJ) landings performed with either a traditional barbell (BB) or a hexagonal bar (HEX) across increasing submaximal loads in recreationally active males. Generally, hip and knee flexion angles and joint mean angular velocities decreased as loads increased. Hip extension and knee flexion moments increased as load increased up to 20 kg, at which point these values decreased. Performing the CMJ with the HEX exhibited increased frontal plane stability compared with the BB group. Additionally, the BB group exhibited stiffer landing strategies, with decreased sagittal plane joint angles …

Factors Associated With Postpartum Depression Among Women Attending Postnatal Clinics In A Tertiary Care Hospital In Nairobi, Kenya, Cecilia Muthoni Njoga
Master of Medicine in Family Medicine
Background
Postpartum depression (PPD) is a major mental health disorder affecting women during the postpartum period with a global prevalence of up to 17.22%. This prevalence has been shown to be higher in low and middle-income countries. In Kenya, about a fifth of women are affected. PPD can lead to poor infant growth and interference with maternal-child bonding. Additionally, women with PPD experience a lower quality of life and their children have an increased risk of developing and psychotic disorders later in life. Understanding the factors associated with PPD is crucial for early diagnosis and intervention. The study aimed to …

Specificity Of Interaction Of Antimicrobial Peptide With Cell Membrane, Srishhti Kumar Jha
Pharmaceutical Sciences (MS) Theses
Antimicrobial resistance (AMR) is an increasing global health threat due to its rising incidence worldwide. Resistant microbial infections have become difficult to treat and pose serious risks to patients. In 2019, AMR was responsible for approximately 1.27 million deaths globally, with numbers continuing to rise. The World Health Organization (WHO) has highlighted the urgent need for new antibiotics with novel mechanisms of action and low toxicity to combat this issue. Antimicrobial peptides (AMPs) represent a promising solution. These peptides exhibit broad-spectrum antimicrobial activity and rapid killing kinetics, reducing the likelihood of resistance development. AMPs primarily target bacterial cell membranes. Their …

Effects Of Perfluorooctane Sulfonate In A Mouse Model Of Alcohol-Associated Liver Disease., Paxton Michelle Brizendine/Ames
Electronic Theses and Dissertations
Perfluorooctane sulfonate (PFOS), a pervasive environmental pollutant, has been increasingly associated with the development of metabolic dysfunction-associated steatotic liver disease (MASLD); nonetheless, its connections with alcohol-associated liver disease (ALD) have not been well studied. This study investigates the hypothesis that PFOS exposure alters hepatic metabolism, thereby leading to alterations in ALD severity. Male C57BL/6J mice were fed isocaloric control or 5% ethanol (EtOH) diet for 15 days. From day 6 of feeding, mice were concurrently gavaged with 1 mg/kg PFOS or 2% Tween-80 vehicle for 10 days, followed by a 5 g/kg EtOH binge dose. PFOS and ethanol co-exposure significantly …

Electronic Theses and Dissertations
The cornea is the most anterior portion of the eye and permits light passage through to retina, allowing formation of a clear image as long as it remains healthy. If the cornea sustains damage, it creates and entrance for foreign body invasion, infection, and ultimately blindness in the immunocompromised eye. Healing the corneal tissue is critical for vision restoration and pain alleviation, as it is the most densely innervated tissue in the body. Growth factors and their cognate receptors are currently under investigation as tools to restore proper corneal physiology. We hypothesize that manipulating the hepatocyte growth factor (HGF) /c-Met …
Metabolic Regulation Of Cardiac Fibroblast Phenotype And Function., Collin Kleis Wells
Metabolic Regulation Of Cardiac Fibroblast Phenotype And Function., Collin Kleis Wells
Electronic Theses and Dissertations
Cardiac fibroblasts are central effectors of cardiac repair after myocardial infarction (MI). In response to signaling cues, they differentiate to a range of phenotypes with robust capacities to synthesize and secrete extracellular matrix (ECM) and signaling molecules. Although activated fibroblast phenotypes are associated with pronounced changes in metabolism, it remains unclear how the metabolic network upholds the effector functions of fibroblasts in the post-infarcted heart. Here, we identified that critical enzymes in the phosphoenolpyruvate (PEP) cycle, i.e. pyruvate kinase muscle-2 (PKM2) and phosphoenolpyruvate carboxykinase-2 (PCK2), are elevated in the heart after MI and examined their role in regulating post-MI remodeling …

Immunopathogenic Crosstalk Between Cancer And The Kidney: A Central Role For Macrophages As Potential Mediators., Dana Hammouri
Electronic Theses and Dissertations
Cisplatin remains a mainstay in the treatment of solid tumors, yet its therapeutic efficacy is frequently compromised by dose-limiting nephrotoxicity. Approximately 30% of patients receiving cisplatin develop acute kidney injury (AKI), which increases the risk of chronic kidney disease (CKD), a leading cause of morbidity and mortality. Despite extensive preclinical efforts, no FDA-approved therapy currently exists to prevent or treat cisplatin-induced nephrotoxicity (CIN). This in part is due to the reliance of preclinical studies on non-cancer animal models that fail to capture the complex physiological alterations associated with malignancy. To address this limitation, we developed a clinically relevant model in …
Intestinal Stromal Cells Play A Critical Role In Protection Mediated By Male Microbiota-Derived Metabolites And Androgens Against Disease In Lupus-Prone Mice., Jing Ma
Electronic Theses and Dissertations
Systemic lupus erythematosus (SLE) is a complex autoimmune disease involving broad immune dysregulation. Despite decades of research, most lupus treatments still have limited effectiveness and can cause serious side effects. Both genetic and environmental factors contribute to lupus susceptibility, and a better understanding of how environmental factors influence disease could guide future therapeutic strategies. SLE shows a strong female predominance. Growing evidence implicates the gut microbiota and sex hormones as key environmental contributors to some autoimmune diseases, including lupus. The gut microbiota can influence host immune function, and interestingly, recent studies have revealed sex-bias in microbiota composition and function. Moreover, …

Dissecting The Heterogeneous Effects Of Opioid Prescribing Limit Laws On Pediatric Mortality: A Multidimensional And Negative Binomial Modeling Approach, Francine R. Vega
Dissertations and Theses (Open Access)
Opioid prescribing for children and adolescents continues to be a significant health crisis in the United States. Early naïve exposure to opioid prescriptions has been linked to later misuse, opioid use disorder, and death. In response to the crisis, many states have implemented opioid prescribing limit laws (OPLLs) aimed at reducing exposure to opioids. These laws vary widely in their approach, including differences in dosage restrictions, prescription duration limits, informed consent requirements, educational provisions, and whether they offer explicit protections specifically for minors. Despite their widespread adoption, there is limited understanding of how heterogeneity in legal regulations affects outcomes for …
Evaluating Quadrupedal Locomotion In Bats: A Geometric Morphometric Comparison Of Vertebral Adaptations Across Mammals, Jessica Upham
Evaluating Quadrupedal Locomotion In Bats: A Geometric Morphometric Comparison Of Vertebral Adaptations Across Mammals, Jessica Upham
Electronic Theses and Dissertations
Flight is the primary locomotion of bats, while quadrupedal locomotion is not often observed and is widely variable among bats. Frugivorous bats in Pteropodidae are more efficient climbers than frugivorous bats in Phyllostomidae and insectivorous bats in Vespertilionidae, while phyllostomids and vespertilionids are better at walking on horizontal surfaces. The aim of this study is to investigate whether bats with differing modes of nonflight locomotion also exhibit disparity in thoracolumbar vertebral morphology. Using geometric morphometrics, we compared the thoracolumbar vertebral shapes of these bat families with other terrestrial and arboreal mammals. The results revealed distinct vertebral shapes among bat families …

Advanced Interactions Of Directed Energy With Retinal Pigment Epithelial Cells And Their Photochemical And Photothermal Responses, Jin B. Ha
Theses & Dissertations
Excess optical radiation can injure the retina through either rapid heat deposition (photothermal damage) or cumulative photo‑oxidative stress (photochemical damage), yet current laser‑safety limits treat these mechanisms as independent. To test that assumption, this dissertation integrated systematic wavelength, duration and temperature‑controlled laser exposures with live/dead fluorescence imaging in a melanin‑loaded hTERT‑RPE1 monolayer model. First, concurrent 447 nm (blue) and 2 µm (infra‑red) beams delivered for 200 s demonstrated a strong thermal–photochemical synergy: each beam alone was sub‑threshold (≤25 % lethality) but together produced 100 % RPE death without exceeding 50 °C, proving that modest heating markedly lowers the photon dose …

Institute for Human Development, East Africa
Background: Early childhood development (ECD) lays the foundation for lifelong health, academic success and social well-being, yet over 250 million children in low- and middle-income countries are at risk of not reaching their developmental potential. Traditional measures fail to fully capture the risks associated with a child’s development outcomes. Artificial intelligence techniques, particularly machine learning (ML), offer an innovative approach by analysing complex datasets to detect subtle developmental patterns.
Objective: To map the existing literature on the use of ML in ECD research, including its geographical distribution, to identify research gaps and inform future directions. The review focuses on …
Regulation Of Icer Degradation And Its Role In Melanoma, Justin Wheelan
Regulation Of Icer Degradation And Its Role In Melanoma, Justin Wheelan
Theses, Dissertations and Culminating Projects
Melanoma is the deadliest form of skin cancer, with 100,640 new cases and 8,290 deaths estimated in the United States in 2024. While targeted therapies and immunotherapy have improved patient outcomes, resistance remains a major challenge, necessitating new therapeutic approaches. Approximately 50% of melanomas harbor BRAFⱽ⁶⁰⁰ᴱ mutations, leading to constitutive MAPK pathway activation. Targeted small molecule therapies such as BRAF and MEK inhibitors are available and initially reduce tumor burden, however resistance frequently occurs, likely through many pathways including compensatory activation of cAMP signaling. ICER (Inducible cAMP Early Repressor), a transcriptional repressor of CREB-mediated gene expression, is absent in melanoma …
Polyphenols For The Mitigation Of Vascular Calcification; In Vitro And In Vivo Studies, Abdullah Altuhami
Polyphenols For The Mitigation Of Vascular Calcification; In Vitro And In Vivo Studies, Abdullah Altuhami
All Theses
Globally, cardiovascular diseases, in most cases associated with calcification, are the main cause of death. However, currently, the only effective cure is to undergo surgery to augment or receive a healthy donor heart, which could be very difficult due to the long waiting list and the associated risks. The possibility of body rejection of the foreign organs is attributed to immunoreaction or the risk of infection, since the donor must be on immunosuppressant drugs that lower the body's immunity and facilitate the body's acceptance of the new organ as one of its own. Taking that into consideration, using tissue-engineered vascular …

This dissertation investigates the application of artificial intelligence in biomedical data acquisition, communication, and analysis to advance neurological research and to enable the early detection of cardiovascular conditions. Despite significant advances in imaging and physiological modalities, challenges persist. Imaging modalities, such as the chemical exchange saturation transfer magnetic resonance imaging (CEST MRI) technique are challenged by a prolonged data acquisition time and high operational costs. In addition, physiological modalities such as electrocardiogram (ECG) sensors face constraints in providing uninterrupted signal monitoring which is crucial for the timely detection of premature cardiac abnormalities. The primary goal of this work is to …
