Effects Of Water Deficit Stress And Mycorrhiza, Azotobacter Chroococcum, And Azospirillum Lipoferum Biofertilizers On Yield And Morphological Traits Of Wheat (Triticum Aestivum L.) Cultivars, Mehdi Rashnou, Farshid Aref, Bahram Amiri, Masoud Rafiee, Mahdi Zare

The Philippine Agricultural Scientist

Crop production in various parts of Iran faces significant constraints due to insufficient water availability, which is a major challenge to agricultural productivity. To study the effects of water deficit stress on shoot and root growth characteristics and seed yield of different wheat (Triticum aestivum L.) cultivars, an experiment was conducted using a randomized complete block design with a split-plot arrangement and 3 replications. The main factor was irrigation treatments (full irrigation during the growing season [S1], water withholding after flowering [S2], and water withholding after grain filling at the milk stage [S3]). The secondary factors were wheat cultivars …

75 | Cana Of Galilee: Excavations At Karm Er-Ras 1999–2011, Yardenna Alexandre

IAA Reports—Monograph Series of the Israel Antiquities Authority

This volume describes the results of multiple small-scale salvage excavations that took place at the site of Karm er-Ras in the Lower Galilee between 1999 and 2011. Archaeological remains of ten strata were revealed, dating from Iron Age II to the Byzantine period, including architecture, pottery, glass, coins and special finds. The archaeological data reveals the history of settlement of this site, and its changing ethnic and religious affinities over some 1500 years. Following detailed analysis of the archaeological data and the literary sources, the author argues for the identification of the Roman-period village at Karm er-Ras with ‘Cana of …

Bile Acid Regulation Of Xenobiotic Nuclear Receptors On The Expressions Of Orosomucoids In The Liver, Ji Ho Suh, Inyoung Cheon, Hyun-Jung Jung, Sung Ho Lee, Mi Jeong Heo, Matthew Deberge, Clavia Ruth Wooton-Kee, Kang Ho Kim

Children’s Nutrition Research Center Staff Publications

The constitutive androstane receptor (CAR) and pregnane X receptor (PXR) are xenobiotic nuclear receptors activated by various xenobiotics, drugs, hormones, and bile acids (BAs). Upon activation, these nuclear receptors play critical roles in regulating systemic energy homeostasis. However, precise mechanisms through which CAR and PXR influence systemic metabolism remain incompletely understood. Here, we investigated the impact of CAR and PXR on the liver-secreted hormone (i.e., hepatokine) expressions in response to BA stress such as cholic acid (CA) feeding. Our analysis revealed that several BA-activated genes, including the well-known CAR/PXR target, aldo-keto reductase family 1, member B7 (Akr1b7 …

Changes In The Fxr-Cistrome And Alterations In Bile Acid Physiology In Wilson Disease, Clavia Ruth Wooton-Kee, Hari K Yalamanchili, Islam Mohamed, Manal Hassan, Kenneth D R Setchell, Monica Narvaez Rivas, Ayse K Coskun, Vasanta Putluri, Nagireddy Putluri, Prasun Jalal, Michael L Schilsky, David D Moore

Children’s Nutrition Research Center Staff Publications

Background: Wilson disease (WD) is an autosomal recessive disorder that results in excessive hepatic copper, causing hepatic steatosis, inflammation, fibrosis, cirrhosis, and liver failure. Previous studies have revealed dysregulation of many farnesoid X receptor (FXR) metabolic target genes in WD, including the bile salt exporter pump, the major determinant of bile flow.

Methods: We tested the hypothesis that the FXR-cistrome is decreased in Atp7b-/- mice in accord with dysregulated bile acid homeostasis.

Results: FXR binding within Atp7b-/- mouse livers displayed surprising complexity: FXR binding was increased in distal intergenic regions but decreased in promoter regions in Atp7b-/- versus wild-type mice. …

A Vacuolar Proton Pump Controls The Post-Germinative Growth Of Rice (Oryza Sativa Ssp. Japonica), Peter James Icalia Gann, Soumen Nandy, Rodrigo Botelho, Kari Vinzant, Mariya Khodakovskaya, Vibha Srivastava

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Post-germinative growth in plants is controlled by sucrose mobilization from the endosperm. Regulation of this process, however, is not fully understood. Transcriptional suppression of the rice vacuolar H+ translocating pyrophosphatase (V-PPase) referred to as VPP5 led to enhanced starch content in mature grains. However, vpp5 suppressed lines displayed a slower post-germinative growth rescuable by sucrose, indicating inefficient sucrose mobilization from the endosperm. Biochemical and gene expression analyses showed a slower rate of starch to sucrose conversion and altered expression of the key starch utilization pathway genes. We hypothesized that the modulation of metabolic activities in the vpp5 lines was based …

Belowground Biomass Shifts Along A Temperate Forest Edge, Lara Holbrook Roelofs

Dartmouth College Undergraduate Theses

Anthropogenic land use change and development has caused widespread global forest fragmentation, resulting in a greater proportion of forests at or near a forest edge. Temperate forests are the most fragmented forest biome, and forests in the Northeastern U.S. are particularly fragmented due to a history of intense land use and development pressure. Nearly a quarter of these forests are now within 30 meters of a forest edge. These edge ecosystems have distinct abiotic and biotic gradients that differentiate them from forest interiors, including increased light, temperature, and exposure to wind and other disturbances, as well as decreases in humidity …

Topodino: Self-Supervised Topological Representation Learning For Neuronal Morphologies, Yasser Binbisher

Master's Theses

Neuronal cell types are categorized by transcriptomic identity, yet their morphological heterogeneity defies this classification. In response, researchers have adopted unsupervised graph representation learning as a tool to reveal morphological variation within single-class transcriptomic types. However, the complex geometry of neuronal morphology—especially long axons and dense dendrites—challenges graph neural networks, which struggle with message propagation across extended structures. To mitigate this, current approaches enforce sub-sampling on neuronal graphs and omit axons entirely, sacrificing critical biological features for computational efficiency. To overcome this trade-off, this thesis introduces TopoDINO, a self-supervised, topology-aware representation learning model designed to preserve the full hierarchical organization …

"The Effect Of Methylobacterium Symbioticum On The Growth And Yield Of Dent Corn And Romaine Lettuce", Sinead Carney

Master's Theses

Nitrogen (N) is an essential nutrient for plant growth and is often a limiting nutrient in cropping systems. An estimated half of applied N fertilizers are lost from cropping systems by processes that can be environmentally destructive, such as leaching and volatilization, and cause economic loss for growers. Effective N biofertilizers offer a means to mitigate the need for high inputs of synthetic N. The objectives of this study were to determine the effects of leaf inoculation with the N-fixing bacteria, Methylobacterium symbioticum, in combination with different rates of urea-N fertilizer on the physiology and yield of dent corn …

Stability Insights From Modeling Chronic Myelogenous Leukemia, Giovani Thai

Master's Theses

This thesis centers around a model for chronic myelogenous leukemia (CML) as it behaves under imatinib treatment, a common medication for CML patients, and the anti-leukemia immune response. The dynamics are represented with a system of nonlinear delay-differential equations first constructed by Kim et al. in 2008, capturing population changes of T-cells and various CML growth stages. We investigate stability in both the clinical and mathematical sense. Through numerical simulations, we computationally incorporate a supplementary treatment plan to determine its effectiveness in aiding immune response and medication in achieving remission and full elimination. The primary goal is to conduct a …

Integrating Methods To Investigate Phytoplankton Dynamics Along Gradients Of A Major Urban River, Nicholas Sheldon

University Honors Theses

Waterways that support human society and life on Earth host superabundant microorganisms which support all ecosystems and food webs: phytoplankton. This study aimed to identify and quantify phytoplankton in the Willamette River in order to understand the dynamics between different phyla. Building on previous studies, which showed that communities of phytoplankton change with the river environment, this work determined how eukaryotic and prokaryotic phytoplankton vary with one another while inhabiting the same river conditions. The approach involved sampling the Willamette river over a weekly time series and combined analytical techniques of qPCR, flow cytometry, and image cytometry to assess population …

Exploring Natural Competence Of Escherichia Coli Through Biofilm Formation, Thulni Liyanaarachchi

University Honors Theses

Escherichia coli is a species not known for natural competence; however, specific growth conditions can induce the process in this bacterium due to the presence of homologous competence genes. These conditions could be met with biofilm formation through an active growth phase in the two-layer architecture. Therefore, my thesis examined whether natural competence is exhibited in E. coli during biofilm formation as determined by the genetic transfer of ampicillin and chloramphenicol-resistance genes between two separate strains. The experiments were broken into three aims to determine the morphology of the biofilm in inter-strain co-cultures and cell-DNA mixes, the effect of …

Investigating A Link Between Dna Repair And Dna Replication In Escherichia Coli Using A Bacterial Two-Hybrid System, Lo Cooper

University Honors Theses

Cells rely on nucleotide excision repair (NER) to remove bulky DNA lesions, such as those caused by UV light. In Escherichia coli, NER involves the UvrABC complex, and includes two main pathways, global genomic repair and transcription-coupled repair (TCR). While TCR, which preferentially removes lesions that block RNA polymerase on the transcribed strand of active genes, is well studied, less is known about whether a similar coupling between repair proteins and replisomes blocked by damaged DNA exists. Such a process has been suggested by a high throughput interactome study, using the replisome subunit HolC as bait and the damage …

Indigenous Science And The Legacy Of Fire: Resilience, Fuels, Mosaics, And Eco-Cultural Landscapes In Oregon’S Coastal And Cascade Range, Julia Alcalá

University Honors Theses

Most of Oregon's western Cascade and Coastal range is a landscape that has historically been considered devoid of mid to low-intensity fires by Western science. However, for time immemorial, Indigenous peoples have been stewarding the forests through the use of "good fire," creating diverse and heterogenous landscapes with mixed fire regimes, ranging from less than a decade to several centuries since the last fire, resulting in a mosaic of patchy forest, oak savannas, prairies, and wetlands. Yet centuries of Indigenous displacement, cultural assimilation, and suppression of cultural burning contributed to this prevailing belief. Despite that, in recent decades, Western scientists …

Kinetic Analysis Reveals T6a-Protein Specificity For T6a And Hn6a Trna Modifications, Cassandra Mae Harker

University Honors Theses

Transfer RNA (tRNA) is essential for accurate translation of genetic information and plays a role in cellular processes such as lipid aminoacylation and bacterial conjugation. Base modifications help tRNA fold correctly and function properly. An important base modification, N6-threonylcarbamoyladenosine (t6A) occurs at position A37 in the anticodon-stem-loop of tRNA. This modification is crucial for decoding ANN codons. Interestingly, an Archeal organism, Methanocaldococcus jannaschii, can have either t6A and hydroxynorvalylcarbamoyl-6- adenosine (hn6A) modification at the same position on tRNAs. As Tsa proteins catalyze the formation of both t6A and hn6A modifications, this raises the question of whether discrimination between these …

Exploring Vaccine Efficacy And Safety For Ms Patients On Immunosuppressant Treatment In Light Of The Covid-19 Pandemic, Rain Pross

University Honors Theses

Multiple sclerosis (MS) is a chronic neurodegenerative autoimmune disorder affecting approximately 2.8 million people worldwide. Despite decades of research to understand the molecular mechanisms of MS pathology, little is known about why the neurodegeneration caused by this illness occurs. For this reason, current treatments for MS target two broader aspects of the disease: relapse management and prevention via disease-modifying therapies. These treatments often involve immunosuppressive mechanisms, creating vulnerability to infectious diseases that became particularly concerning during the COVID-19 pandemic. This literature review examines the safety and efficacy of vaccination for MS patients on immunosuppressant therapies, highlighting the novel mRNA vaccines …

Integrating High Throughput Phenotyping Approaches To Characterize Plant Traits And Support Nutrient Management Research, Katie J. Bathke

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Over the past decade, considerable research has addressed the social, economic, and agronomic challenges posed by imbalanced nutrient applications, particularly nitrogen and, more recently, sulfur. In response, high throughput plant phenotyping, as one of the latest approaches, has contributed to the development of innovative techniques for assessing key plant phenotypes under stress over time in both field and greenhouse environments. However, there is a limited number of studies applying these techniques for nutrient management, particularly in scenarios where two abiotic stressors coexist, such as the combination of water stress and nitrogen deficiency, or concurrent nitrogen and sulfur deficiencies.

A Review On The Cytogenetic Integrity Of Micropropagated Plants [Review Paper], Eliaza Alumbro Peniton Jr

The Philippine Agricultural Scientist

Cytogenetic stability is essential for the survival of micropropagated plants. While micropropagation allows rapid propagation of plants with desirable phenotypes, it may also produce genetic variations that are, at times, cytogenetically observable. Factors affecting these variations are not fully understood, and micropropagation protocols are optimized to produce genetically stable regenerants. The genetic stability of micropropagated plants is traditionally assessed by comparing the phenomorphological traits of the regenerants to the mother plant. However, genetic variation does not often result in obvious morphological changes. Therefore, molecular and cytogenetic markers are typically used to evaluate the genetic variations of regenerants. Moreover, analyzing plant …
