Leaf cuticle is the waxy envelope that protects leaves from desiccation, UV damage, and abrasion. The cuticle encodes information about a plant's chemistry and leaf epidermal and stomatal cell morphology. Fossil leaf cuticle has been used to determine taxonomic affinities for almost two centuries and recognized in recent decades for its value in reconstructing paleoenvironments and paleoclimates, especially atmospheric CO2. Fossil leaf cuticle preparation techniques are typically reported as single workflows tied to individual studies, starting with finding fossils in the field through the steps of preparing cuticle for chemical and morphological analysis, including decisions about type of microscopy and …

"The Role Of Venous Excess Ultrasound Score In Optimizing Acute Heart Failure Diagnosis And Prognosis, Saoussen Antit, Sarra Romdhane, Imen Mtiri, Lilia Zakhama

Journal of the Saudi Heart Association

Acute heart failure (AHF) is a critical condition with significant morbidity and mortality, necessitating timely and accurate diagnosis for effective management.

The Venous Excess Ultrasound (VExUS) score has emerged as a non-invasive diagnostic tool, aimed at evaluating venous congestion through ultrasound. This scoring system integrates assessments of the inferior vena cava, hepatic veins, portal veins, and renal venous flow to quantify congestion severity. By providing a real-time assessment of venous pressure, the VExUS score has shown potential in optimizing early diagnosis of AHF and predicting outcomes and overall prognosis.

Recent studies suggest that incorporating the VExUS score into clinical practice …

Bridging The Gap Between Muslim Students And School Leadership In The United States, Sahar Khawaja

Electronic Theses and Dissertations

Entering the third decade of the 21st century, the political landscape in the United States presents a challenging environment for Muslims, mirroring the global trend of oppression and discrimination faced by this community (Neptune, 2021). Despite being the fastest-growing demographic in the nation (Lipka, 2017), Muslim Americans increasingly encounter discrimination. By actively addressing and dismantling these stereotypes, educators can cultivate an inclusive environment where the needs of Muslim students are understood and respected. Understanding the stories and experiences of these students is vital for school leaders, as it enables the creation of an environment where every student feels a genuine …

Radial Glia Integrin Avb8 Regulates Cell Autonomous Microglial Tgfβ1 Signaling That Is Necessary For Microglial Identity, Gabriel Mckinsey, Nicolas Santander, Xiaoming Zhang, Kilian Kleemann, Lauren Tran, Aditya Katewa, Kaylynn Conant, Matthew Barraza, Kian Waddell, Carlos Lizama, Marie La Russa, Ji Hyun Koo, Hyunji Lee, Dibyanti Mukherjee, Helena Paidassi, E. S. Anton, Kamran Atabai, Dean Sheppard, Oleg Butovsky, Thomas Arnold

Department of Medicine Faculty Papers

Microglial diversity arises from the interplay between inherent genetic programs and external environmental signals. However, the mechanisms by which these processes develop and interact within the growing brain are not yet fully understood. Here, we show that radial glia-expressed integrin beta 8 (ITGB8) activates microglia-expressed TGFβ1 to drive microglial development. Domain-restricted deletion of Itgb8 in these progenitors results in regionally restricted and developmentally arrested microglia that persist into adulthood. In the absence of autocrine TGFβ1 signaling, microglia adopt a similar phenotype, leading to neuromotor symptoms almost identical to Itgb8 mutant mice. In contrast, microglia lacking the canonical TGFβ signal transducers …

Synthetic Protein Mimetic Based Therapies For Neurodegeneration, Nicholas H. Stillman

Electronic Theses and Dissertations

Protein-protein interactions (PPIs) are crucial for the regulation of a majority of, if not every fundamental cellular process. Despite their role in regular biological processes, dysregulated and/or aberrant protein-protein interactions (aPPIs) are often related to the onset of disease including cancer, viral infection, and amyloid diseases. aPPIs have historically been deemed ‘undruggable’ due to their large surface area and lack of a binding cavity; however, today, more than 40 disease-related aPPIs have been targeted with small molecules and several of those have reached clinical trials.

A class of synthetic protein mimetics called oligopyridylamides (OPs) has been shown to inhibit disease-related …

This study classified cows’ foraging behaviors using machine learning (ML) models evaluated through random test split (RTS) and cross-validation (CV) data partition methods. Models included Perceptron, Logistic Regression, Support Vector Machine, KNearest Neighbors, Random Forest (RF), and XGBoost (XGB). These models classified activity states (active vs. static), foraging behaviors (grazing (GR), resting (RE), walking (W), ruminating (RU)), posture states (standing up (SU) vs. lying down (LD)), and posture combinations with rumination and resting behaviors (RU_SU, RU_LD, RE_SU, and RE_LD). XGB achieved the highest accuracy for state classification (74.5% RTS, 74.2% CV) and foraging behavior (69.4% CV). RF outperformed XGB in …

Between Fire And Water: Miyazawa Kenji's Reimagining Of Opposites In Ginga Tetsudō No Yoru, Taishi Neilsen

University Honors Theses

This thesis explores how Japanese writer Miyazawa Kenji playfully uses opposites and binaries to create thematic richness in his famous children's story Ginga tetsudō no yoru (Night on the Milky Way Railroad). Despite being a children's book, the text works with mature themes such as loneliness, grief, and purpose, themes which are elevated through Kenji's idiosyncratic stylings. Through a close reading of the original Japanese text, the author isolates moments where Kenji conveys his Nichiren Buddhist worldview as part of his proselytizing mission, as well as moments that increase thematic richness, resulting in a multifaceted text that continues …
