Turkish Journal of Agriculture and Forestry
Sewage sludge management represents a major challenge in Europe, carrying significant environmental and legal implications that require strong regulatory enforcement. Here, we explore the legislative measures, technological developments, and environmental impacts of sewage sludge management in Central Europe (Czechia, Slovakia, Germany, Austria, and Poland). Sludge management is regulated at the EU level through a series of directives (e.g., Council Directive 86/278/EEC, which forms the basis of national regulatory frameworks). However, national adaptations vary considerably: Croatia and Slovenia have invested in sludge phosphorus-recovery systems, while Poland and Slovakia have focused on the agricultural use of sludge as a fertilizer. Several countries, …

Robust Soil Moisture Content Detection Based On Data Augmentation Under Different Testing Conditions, Yang Li, Chenghao Liu, Jing Nie, Jingbin Li
Turkish Journal of Agriculture and Forestry
Accurate and cost-effective monitoring of soil moisture content is essential for the development of precision agriculture and the optimization of water resource management. While low-frequency acoustic signals are used to detect soil moisture content, models trained with controlled laboratory acoustic data often exhibit significant performance degradation with field data due to their sensitivity to environmental noise, soil heterogeneity, and structural variations. This study proposes a novel framework to enhance model robustness and generalization by integrating a WGAN-GP network data augmentation strategy into the soil moisture content workflow. This framework is designed to generate high-quality and diverse data on different soil …

Beyond Autophagic Dysregulation: Vma21 Deficiency Reveals Altered Vesicle Trafficking And Broadens The Pathogenic Framework Of X-Linked Myopathy With Excessive Autophagy, Christian Suarez
Arts & Sciences Graduate Student Theses and Dissertations
Maintenance of protein homeostasis is essential for cellular function and depends on the coordinated regulation of protein synthesis and degradation. The major intracellular pathways responsible for protein degradation are the ubiquitin-proteasome system (UPS) and autophagy. Disruption of these processes has been implicated in a broad range of diseases, including neuromuscular disorders. X-linked myopathy with excessive autophagy (XMEA) is a rare vacuolar myopathy caused by mutations in VMA21, which encodes an assembly chaperone required for proper assembly of the vacuolar H⁺-ATPase (V-ATPase), the primary proton pump responsible for acidifying intracellular compartments, including lysosomes. Although impaired lysosomal acidification and autophagic dysregulation have …

Enhancing Salinity Tolerance In Phyla Nodiflora L. With Potassium Humate: Crosstalk Between Osmolytes, Antioxidants, And Mineral Uptake, Fatemeh Sadeghi, Somayeh Esmaeili, Mehrangiz Chehrazi
Turkish Journal of Agriculture and Forestry
Salinity stress impairs plant growth, nutrient homeostasis, and metabolism, particularly in arid ecosystems. Phyla nodiflora, a ground cover used for erosion control, shows preliminary salinity tolerance, but the mechanistic basis of its long-term adaptation and the potential for enhancement via potassium humate (KH) were unknown. Plant growth, key biochemical attributes, and nutrient uptake were assessed to elucidate how KH modulates physiological performance under increasing salinity. In a 129-day greenhouse experiment, plants were exposed to five salinity levels (0 to 16 dS m⁻¹ NaCl) and three KH concentrations (0, 500, and 1000 mg L⁻¹). Severe salinity (16 dS m⁻¹) without KH …

The Gut-Bladder Axis: How Symbiont Microbes Alter Urinary Tract Infections, Benjamin S. Olson
The Gut-Bladder Axis: How Symbiont Microbes Alter Urinary Tract Infections, Benjamin S. Olson
Arts & Sciences Graduate Student Theses and Dissertations
Urinary tract infections (UTIs) are among the most common bacterial infections worldwide. Consequently, they are one of the leading indications for antibiotic prescription. Despite the typically successful treatment of an acute UTI, recurrent infections are exceedingly common, particularly among women. Nearly a quarter of otherwise healthy women will suffer recurrent UTIs (rUTI) after a primary UTI; why these select individuals are continually afflicted is unkown. There are no successful therapeutics to treat rUTI representing a gap not just in the medical toolkit but in our understanding of why rUTI is so prevalent. There are many hypotheses for the risk factors …
Integrative Evidence For Cryptic Diversity In The Thomomys Mazama Species Complex: Phylogenetics, Cranial Morphometrics, And Ecological Niche Modeling, Jessica Kate St. Michael
Integrative Evidence For Cryptic Diversity In The Thomomys Mazama Species Complex: Phylogenetics, Cranial Morphometrics, And Ecological Niche Modeling, Jessica Kate St. Michael
Dissertations and Theses
The population genetic structure and geographic distribution of the pocket gopher genus Thomomys Wied-Neuwied, 1839, lends itself to speciation events. Conserved morphology, ecological specialization, and high rates of molecular evolution may increase the probability of allopatric speciation, thereby contributing to the presence of morphologically cryptic taxa. In light of these patterns of evolution, we assessed genetic divergence and phylogenetic relationships, cranial morphometric differentiation, and ecological divergence among taxa in the Thomomys mazama species complex to test the hypothesis that T. mazama is a single species. Species delimitation analysis using Bayesian Poisson Tree Processes (bPTP) and data from the mitochondrial cytochrome …

New Locality Records And Future Habitat Suitability Of Sassanidotus Gracilis (Birula, 1900) (Scorpiones: Buthidae) In The Iran–Afghanistan–Pakistan Arid Belt, Ersen A. Yağmur, Kerim Çiçek, Homa Barati, Mohammad Moradi
Euscorpius
This study reports new locality records from Iran and a climate-based habitat suitability assessment for Sassanidotus gracilis (Birula, 1900) (Scorpiones: Buthidae) in the Iran–Afghanistan–Pakistan arid belt. We document new specimens from Sistan and Baluchestan Province, Iran, with an updated distribution map and illustrations, and we model the species' potential distribution across south-eastern Iran and adjacent parts of Afghanistan and Pakistan.
Habitat suitability was associated mainly with precipitation seasonality, precipitation of the wettest month, precipitation of the driest month, and slope. In an arid setting these rainfall variables are unlikely to indicate a need for moist habitat; they more plausibly track …

Effects Of Human-Animal Interaction On Positive Youth Development: A Replication Study, Allison Pachunka, Jay Jeffries, Lisa Karr, Lena Luck, Bryan A. Reiling, Douglas H. Schultz, Jeffrey R. Stevens
People and Animals: The International Journal of Research and Practice
Interacting with animals can improve health and well-being across the lifespan. Some programs such as 4-H and FFA center around youth interacting with animals, potentially enhancing youth development. Mueller (2014) investigated whether these interactions and attitudes about animals influenced measures of positive youth development. The aim of our studies was to replicate Mueller’s methods and extend her work by evaluating whether membership in animal-focused youth programs moderate associations between interactions, attitudes, and positive youth development. We did not find strong relationships among human–animal inter-action and positive youth development, which failed to replicate Mueller’s findings. However, we did find relationships between …

Journal of Food and Drug Analysis
Atopic dermatitis (AD) is a chronic inflammatory disease characterized by recurrent bacterial infections that cause pruritus, erythema, xerosis and thickening. Cajanus cajan root extract prepared with 95% ethanol (EECR95) has been shown to possess antioxidant, anti-inflammatory, and antibacterial properties in previous studies. This study aimed to evaluate EECR95’s ability to improve AD by inhibiting methicillin-resistant Staphylococcus aureus (MRSA) growth and reducing inflammation. This study found EECR95 effectively inhibits MRSA growth (IC50 = 103.74 μg/mL) and reduces pro-inflammatory cytokine production in an MRSA-keratinocyte-macrophage model. LC/MS/MS analysis revealed the presence of active compounds- flavonoids, isoflavones, and flavonoid glycosides, highlighting EECR95's potential …
The Defining Role Of Ago4 And Its Catalytic Activity During De Novo Rna-Directed Dna Methylation, Tianyi Li
The Defining Role Of Ago4 And Its Catalytic Activity During De Novo Rna-Directed Dna Methylation, Tianyi Li
Arts & Sciences Graduate Student Theses and Dissertations
Plant transposable elements and transgenes are continuously targeted for transcriptional repression via the pathway of RNA-directed DNA methylation (RdDM). Although perpetual RdDM of the endogenous genomic loci has been well studied in the field, much less is known about the de novo RdDM pathway, the pioneering round of DNA methylation responsible for triggering and initiating silencing of new transgenes. Despite being two distinct pathways, both perpetual and de novo mechanisms of RdDM require the production of small interfering RNAs (siRNAs) and the key proteins of the ARGONAUTE4 (AGO4) clade. However, the order and likely mechanism of recruitment of AGO4 to …
Interplay Between Patterning And Morphogenesis During Zebrafish Embryonic Development, Chia-Teng Chang
Interplay Between Patterning And Morphogenesis During Zebrafish Embryonic Development, Chia-Teng Chang
Arts & Sciences Graduate Student Theses and Dissertations
Patterning and morphogenesis occur concurrently during embryonic development. In many contexts, both processes are regulated by morphogen signaling: morphogens specify spatially organized cell identities while also influencing the cell behaviors that shape tissues. This creates a reciprocal problem. Morphogen signaling can affect how cells move, while cell movement can change how cells experience and interpret morphogen signals. This dissertation investigates this reciprocal problem during zebrafish gastrulation and neurulation. First, it examines how the ventral-to-dorsal bone morphogenetic protein (BMP) activity gradient regulates germ-layer morphogenesis during gastrulation. BMP signaling is known to pattern dorsal–ventral cell fate and regulate mesodermal convergence and extension …

MALT1 protease is an intracellular signaling molecule that promotes tumor progression via cancer cell-intrinsic and cancer cell-extrinsic mechanisms. MALT1 has been mostly studied in lymphocytes, and little is known about its role in tumor-associated macrophages. We show that MALT1 is expressed in glioblastoma (GBM)-associated macrophages. Mechanistically, GBM tumor cells induce a MALT1-NF-κB signaling axis in macrophages, leading to enhanced macrophage migration and polarization toward an immunosuppressive ('M2-like') phenotype. Inactivation of MALT1 protease promotes transcriptional reprogramming that reduces migration and restores a macrophage anti-tumor 'M1-like' phenotype. Preclinical in vivo analysis shows that MALT1 inhibitor treatment results in immuno-reactivity of GBM-associated macrophages …

Escherichia Coli Concentrations In Sand And Water At Tributary-Influenced Lake Michigan Beaches, Josie Elaine Kuhlman
Escherichia Coli Concentrations In Sand And Water At Tributary-Influenced Lake Michigan Beaches, Josie Elaine Kuhlman
Masters Theses
Contamination of public recreational water and sand is a human health concern, creating a management challenge for public health officials. Past research has shown that Escherichia coli can persist in sediment and can be washed into recreational water. Currently, beach monitoring practices only utilize E. coli concentrations in water samples to determine beach safety and do not consider potential exposure to sediment/sand concentrations. In this study, I investigated the relationship between E. coli concentrations in water and sand samples, which will aid public health officials in making more informed decisions about beach closures. I utilized culture-based measurements of E. coli …

The endometrium undergoes extensive cyclical remodeling essential for reproductive success; however, the molecular mechanisms governing these processes in donkeys (Equus asinus) remain poorly characterized. To address this gap, we performed high-throughput RNA sequencing on endometrial tissues collected from Dezhou donkeys (n = 16) at four post-ovulation stages: Day 0 (ovulation), Day 3 (early luteal), Day 7 (mid-luteal), and Day 18 (late luteal/pre-luteolysis). Differential gene expression analysis, Gene Ontology enrichment, and KEGG pathway mapping were conducted to characterize temporal transcriptomic dynamics. We identified 2,474, 6,548, and 1,288 differentially expressed genes in Day 0 versus Day 3, Day 0 versus …

Phishing attacks continue to evolve in sophistication, rendering static detection methods increasingly ineffective. Existing URL-based approaches suffer from limited adaptability to emerging phishing patterns, mislabeled training data, and insufficient validation protocols. This paper proposes a hybrid phishing URL detection system that integrates Fuzzy C-Means (FCM) clustering with XGBoost classification, enhanced by a novel Micro Adaptive Feature Extractor (MAFE). The system employs a multi-stage pipeline: feature engineering generating 36 statistical and interaction features, MAFE producing 15 adaptive features through class-aware dynamic weighting, micro-pattern detection, and entropy analysis, and FCM with K=2 clusters providing soft membership features to XGBoost. A two-pass confidence-based …
