Khsrp-Mediated Decay Of Axonally Localized Prenyl-Cdc42 Mrna Slow Nerve Regeneration, Matthew D. Zdradzinski, Lauren S. Vaughn, Samaneh Matoo, Kayleigh Trumbull, Terika P. Smith, Davis Noblitt, Courtney N. Buchanan, Ashley Loomis, Elizabeth Thames, Seung Joon Lee, Nora Perrone-Bizzozero, Qun Lu, Jessica M. Larsen, Jeffery L. Twiss

The small GTPase CDC42 promotes axon growth through actin filament polymerization and this growth is driven by axonal localization of the mRNA encoding the prenylated CDC42 isoform (Prenyl-Cdc42). Here, we show that axonal Prenyl-Cdc42 mRNA levels and the mRNA’s translation are decreased by growth-inhibiting stimulation and increased by growth-promoting stimulation. In contrast, axonal RhoA mRNA transport and translation are increased by growth-inhibiting but unaffected by growth-promoting stimuli. Localized increase in KHSRP in response to growth inhibitory stimulation, through elevation of intracellular Ca²⁺, promotes decrease in axonal levels of Prenyl-Cdc42 mRNA. Distinct 3’UTR motifs regulate transport and …

Dissolved Organic Matter Composition Differs Across Water Types In Mid-Atlantic And Great Lakes Coastal Regions, Jesse Alan Roebuck, Allison N. Myers-Pigg, Peter Regier, Nicholas D. Ward, Matthew J. Cooper, Kenneth M. Kemner, Amy Marcarelli, Elizabeth C. Minor, Michael Philben, Bongkeun Song, Rodrigo Vargas, Jianqiu Zheng

Dissolved organic matter (DOM) in coastal surface waters influences local water quality and is an important component of biogeochemical cycling in coastal systems. Many studies have highlighted transformations of DOM along longitudinal river to estuary transects; however, processes that alter DOM composition along lower reaches of rivers and nearshore estuarine waters is poorly understood. The high productivity of coastal environments and their limited representation in Earth System Models further highlights a need for better understanding of DOM transformations along coastal reaches. We leverage a spatially distributed community sampling effort that spans coastal ecosystems across two regions to identify broad spatial …

Paintings Analysis Using Copilot Ai: The Case Of Winston Churchill And Art In His Life, Yuri Zagvazdin

Learning and Educational Center Virtual Teaching and Learning Conference

The objective of this presentation is to demonstrate a method for analyzing artistic style and its potential evolution using the Copilot AI platform. As a case study, I explore the paintings of Winston Churchill (1874–1965), the British Prime Minister, who was also a passionate and prolific painter. Although Churchill began painting in his forties, he produced over 500 works, with his final piece completed in 1962.

Churchill frequently painted scenes from Southern France and Morocco—locations he returned to repeatedly throughout his artistic life. Remarkably, he continued painting even after suffering multiple cerebrovascular accidents. Stroke-induced brain damage is typically detrimental to …

Screening Of Potential Plant Growth‐Promoting Rhizobacteria (Pgpr)-Assisted Phytoremediation To Mitigate Lead Toxicity In Uae Soils, Zeinab A. Mohamed

Thesis/ Dissertation Defenses

Plant growth-promoting actinobacteria can enhance plant resilience to heavy metal contamination. This study evaluated the effects of 1-aminocyclopropane-1-carboxylate deaminase (ACCD)-producing rhizosphere-competent (RC) and non-rhizosphere-competent (NRC) actinobacterial strains on corn growth and lead (Pb) tolerance. A greenhouse experiment was conducted under Pb stress [1000 mg/kg soil as Pb(NO₃)₂] to compare the two isolates. Inoculated plants performed better than uninoculated controls, particularly in non-contaminated soils. Under Pb stress, the isolates #22 (NRC) and #30 (RC) significantly enhanced plant height, dry weight, and chlorophyll content, with RC isolate #30 exhibiting the most pronounced effects. Identified as Streptomyces mirabilis UAE2, isolate #30 reduced electrolyte …

Isolation And Characterization Of Plant Growth Promoting Rhizobacteria From Soils In The Uae And Their Effect On Plant Salt Tolerance, Layla Zayed Almazrouei

Thesis/ Dissertation Defenses

Plants are constantly challenged by environmental stresses that restrict their growth and productivity. In the United Arab Emirates (UAE), soil salinity is a critical barrier to agriculture, particularly for tomato (Solanum lycopersicum), which is highly sensitive to moderate salinity levels (>2.5 dS m⁻¹). This study explored the potential of plant growth–promoting rhizobacteria (PGPR), especially actinobacteria, to enhance salt tolerance in tomato. The objective was to evaluate the effeccts of rhizosphere-competent (RC) and non-rhizosphere-competent (NRC) PGPR on plant physiology and yield in saline sandy soils. Actinobacterial strains were isolated from the tomato rhizosphere were screened for the production of 1-aminocyclopropane-1-carboxylic …

Analysis Of An Effective Training Curriculum: Solutions Toincrease Participants' Interest In Training Teachingmaterials, Maulidya Husnul Khatimah, Yoto Yoto

Jurnal Pendidikan Sains

This research is important because it analyzes the curriculum as a primary tool for generating and maintaining participant interest. Curricula that are irrelevant, monotonous, or misaligned with participant needs are often the main causes of low motivation and participation. Furthermore, this research encourages the exploration and implementation of more innovative teaching methods and materials in training curricula. External pressure in the form of demands or instructions, rather than internal motivation, drives most training activities. This can reduce engagement and learning effectiveness. To overcome this, training institutions need to design programs that are relevant, flexible, and able to encourage participants' intrinsic …

Augmented Reality-Assisted E-Module On Temperature Andheat Content (Emarks), Tetri Sabrina, Ika Mustika Sari, Dedi Sasmita

Jurnal Pendidikan Sains

Temperature and heat content (calor) material in physics often involves concepts and phenomena that are difficult to observe directly or are abstract (such as energy transfer, particle movement, and changes in state). EMARKS (AR-based E-modules) are important because Augmented Reality (AR) allows the visualization of these abstract concepts in the form of interactive 3D models in the user's real environment. This helps students understand the concepts more concretely and easily. The development of E-modules is an innovation in learning media that is relevant to the demands of the digital era and the needs of modern students. The use of advanced …

The Effect Of Guided Inquiry Model With Deep Learningapproach On Student’S Hots In Elements, Compounds,And Mixtures At Junior High School, Friska Pakpahana, Retno Dwi Suyanti

Jurnal Pendidikan Sains

The current education curriculum places a strong emphasis on developing HOTS skills (such as analyzing, evaluating, and creating) to prepare students for the challenges of the 21st century. School learning often focuses on lower-level cognitive domains (memorizing and understanding). This research seeks to address this gap by offering a potentially effective learning model. The guided inquiry model positions students as active participants in learning, encouraging them to investigate, discover, and formulate concepts independently with teacher guidance. This strongly supports the development of critical thinking and problem-solving skills. Therefore, this study aims to analyze the effect of the guided inquiry model …

Development Of E-Lkpd Assisted By Phet Colorado Basedon Discovery Learning: Critical Thinking Skills On Lightmaterial At Junior High School, Flora Yani Saragih, Pintor Simamora

Jurnal Pendidikan Sains

Critical thinking is necessary for 21st-century pupils, but PISA data suggest that Indonesian students, especially junior high school students, lack it. The junior high science/physics light material is abstract and involves in-depth reasoning (reflection, refraction, and shadow generation). Without critical thinking, kids memorize formulas or notions without analyzing real phenomena. Discovery learning involves pupils discovering concepts via observation and experimentation. Critical thinking requires initiative, exploration, and reasoning, which these foster. Therefore, this study aims to develop E-LKPD based on Discovery Learning assisted by an interactive simulation of PhET Colorado to strengthen the critical thinking skills of grade VIII students on …

Parameterizing Ion–Lipid Interactions From Local Clusters To Reproduce Experimental Bulk Properties Of Lipid Bilayers, W. Matthew Saunders

USF Tampa Graduate Theses and Dissertations

Phospholipids are the main component of cell membranes, providing a delimiting boundary for cells from their environments or from their organelles from the cytosol. Thiscompartmentalization allows cells to maintain quite different solutions within their cells and organelles, including different mixtures dissolved ions. Consequently, these membranes are constantly flanked by complex mixtures of salts at varied concentrations. To study membrane structure, one cannot neglect the contribution of the salts in the local solution. Ions perturb bilayer structure via specific interaction with the phospholipids, primarily with the headgroups. Experimental studies of these systems are somewhat at odds — scattering experiments with different …

In the 21st century, several major viral outbreaks have occurred, including the 2002 severe acute respiratory syndrome coronavirus (SARS), the 2009 H1N1 influenza pandemic, the 2012 Middle East respiratory syndrome (MERS), the 2014 Ebola virus outbreak, and most recently, the emergence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in 2019. SARS-CoV-2 is a positive-sense, single-stranded RNA virus of the Betacoronavirus genus in the Coronaviridae family. First identified in Wuhan, China, the virus quickly spread …

Program Transition Success: A Practical Guide For Educators Moving Sbae Programs, Evey Choat

Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research

What tools, strategies, and support systems can help agriculture educators navigate leadership transitions and sustain program success when moving between schools or communities? Teacher mobility and leadership transitions within School-Based Agricultural Education (SBAE) present unique challenges to program continuity, community relations, and professional sustainability. Unlike other subject areas, SBAE teachers often manage multifaceted responsibilities—as classroom instructors, FFA advisors, and community liaisons—making transitions between programs especially complex. This project addresses the lack of structured support for educators navigating these transitions by developing a Program Transition Guide specifically tailored to the needs of agricultural educators in Nebraska.

Designing powerful and unbiased genomic studies requires accurate assessment of familial relatedness even when this information is not captured from participants. Characterization of pairwise degrees of relatedness from participants' genetic data enables reconstruction of pedigrees, and several pedigree reconstruction tools have emerged in the last decade. However, limitations of these tools include high computational burden in large datasets, reliance on external information, reduced accuracy in admixed populations, and most notably, an inability to accurately reconstruct pedigrees when only a subset of family members is represented in the genetic data. To improve pedigree reconstruction in large-scale data and in pedigrees with …

Renal cell carcinoma (RCC) accounts for 90% of adult renal cancer cases and is characterized by significant heterogeneity within its tumor microenvironment. This study tests the hypothesis that tumor-associated macrophages (TAMs) influence RCC progression and patient response to treatment by investigating the prognostic implications of TAM signatures. Utilizing independent single-cell RNA sequencing data from RCC patients, we developed eight distinct TAM signatures reflective of TAM presence. A LASSO Cox regression model was constructed to predict survival outcomes, evaluated using the TCGA dataset, and validated across independent RCC cohorts. Model performance was assessed through Kaplan-Meier survival plots, receiver operating characteristic (ROC) …

Mixed-lineage leukemia (MLL) rearrangements and Nucleophosmin-1 (NPM1) mutations are associated with acute leukemias whose pathogenesis is critically influenced by protein-protein interactions between menin and MLL. We hypothesized that targeting the menin-MLL interaction using DS-1594b and blocking the antiapoptotic BCL-2 protein using venetoclax may promote differentiation and enhance eradication of MLL-rearranged and NPM1-mutated leukemias models. We treated acute myeloid leukemia (AML) cell lines with MLL rearrangements, NPM1 mutations, other leukemias and primary samples from AML patients with venetoclax alone, DS- 1594b alone, and their combination. We measured proliferation, viability, apoptosis, and differentiation using a variety of cellular assays, Western blotting, and …
