Evaluating The Performance Of Broccoli (Brassica Oleracea Var. Italica) In The Sandponics System Using Brackish Water With Biochar And Compost, Gabriel Oyebode

Theses and Dissertations

Some of the most pronounced effects of climate change on agricultural output include the depletion of freshwater resources and heightened salinization of arable land, especially in arid and semi-arid regions, adversely affecting crop yields. Many economic vegetable crops including members of the brassica family are sensitive to salt-stress. The use of organic soil amendments such as biochar and compost as complimentary nutrient sources in the sandponics system can improve the performance of crops. The study aimed to evaluate the effect of organic amendment on the growth performance and yield of broccoli and Nile tilapia (Oreochromis niloticus) under brackish …

Excavations On The Southwestern Margins Of Giv‘Ati Parking Lot, Jerusalem: Markers Of Byzantine–Early Islamic Transition (Pp. 303–338), Yana Tchekhanovets

'Atiqot

The small-scale excavation on the southwestern margins of Giv‘ati Parking Lot exposed important findings dating to the transition between the Byzantine and Early Islamic periods. A flagstone-paved street dating from the Byzantine period was exposed, representing one of the major thoroughfares of Jerusalem that served an important pilgrimage route. This street ceased to exist at the beginning of the Early Islamic period when the function of the area changed from residential to industrial. The remains of a small-scale metallurgical workshop, including numerous copper alloy fragments, metal slags, pottery crucible fragments and large amounts of ash, were dated to the Umayyad …

The Role Of Biofilm Matrix On The Growth, Survival, And Diagnosis In Enterobacteriaceae, Kavi Bharathi R

Theses and Dissertations

Bacteria in nature live together encased in a matrix creating community ecosystems called biofilms, this structured space protects them from hostile environments. This study aimed to understand the role of the biofilm matrix in the growth and survival of Enterobacteriaceae. Our hypothesis proposes that subgroups of individuals within a biofilm can specialize in the production of different matrix components.

Matrix expression is metabolically costly, despite its unicellular simplicity, microbes can coordinate complex behaviour like sharing of matrix between producers and non-producers as an adept evolutionary strategy. Their resilience to stress during biofilm formation was studied to assess their abilities to …

Pantoea agglomerans is one of four Pantoea species reported in the USA to cause bacterial rot of onion bulbs. However, not all P. agglomerans strains are pathogenic to onion. We characterized onion-associated strains of P. agglomerans to elucidate the genetic and genomic signatures of onion-pathogenic P. agglomerans. We collected > 300 P. agglomerans strains associated with symptomatic onion plants and bulbs from public culture collections, research laboratories, and a multi-year survey in 11 states in the USA. Combining the 87 genome assemblies with 100 high-quality, public P. agglomerans genome assemblies we identified two well-supported P. agglomerans phylogroups. Strains causing severe …

Spatiotemporal Variability And Functional Redundancy Obscure Effects Of Urbanization On Strawberry Pollinators, Kyla D. Schulte, Caleb J. Wilson, Anna Tawril, Mary A. Jamieson

Entomology Faculty Publications

Pollination services across rural–urban gradients may vary as land cover and other environmental attributes differentially influence pollinators. Most studies examining crop pollination, however, have been conducted in rural environments, while research in urban areas has lagged behind despite growing interest in urban agriculture. In this study, we hypothesized that increased urbanization would alter pollinator community composition due to a reduction in natural areas within the surrounding landscape, potentially decreasing pollinator abundance. To evaluate this hypothesis, we conducted a three-year study using strawberries as a focal study crop. We characterized the abundance, diversity, and community composition of bees across 10 farms …

Trmt1l-Catalyzed M22g27 On Tyrosine Trna Is Required For Efficient Mrna Translation And Cell Survival Under Oxidative Stress, Sseu-Pei Hwang, Han Liao, Katherine Barondeau, Xinyi Han, Cassandra Herbert, Amirtha Shekar, Patrick A Limbach, Jeffrey T Chang, Catherine Denicourt

Faculty, Staff and Student Publications

tRNA modifications are critical for several aspects of their functions, including decoding, folding, and stability. Using a multifaceted approach encompassing eCLIP-seq and nanopore tRNA-seq, we show that the human tRNA methyltransferase TRMT1L interacts with the component of the Rix1 ribosome biogenesis complex and binds to the 28S rRNA as well as to a subset of tRNAs. Mechanistically, we demonstrate that TRMT1L is responsible for catalyzing N2,N2-dimethylguanosine (m22G) solely at position 27 of tRNA-Tyr-GUA. Surprisingly, TRMT1L depletion also impaired the deposition of 3-(3-amino-3-carboxypropyl) uridine (acp3U) and dihydrouridine on tRNA-Tyr-GUA, Cys-GCA, and Ala-CGC. TRMT1L knockout cells have a marked decrease in tRNA-Tyr-GUA …

Tancler, Bach V. Tran, Rhonda Kean, Alexandra R. Steck, Luis A. Martinez, Elahe A. Mostaghel, D. Craig Hooper, Felix J. Kim

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Adaptive immune resistance in cancer describes the various mechanisms by which tumors adapt to evade anti-tumor immune responses. IFN-γ induction of programmed death-ligand 1 (PD-L1) was the first defined and validated adaptive immune resistance mechanism. The endoplasmic reticulum (ER) is central to adaptive immune resistance as immune modulatory secreted and integral membrane proteins are dependent on ER. Sigma1 is a unique ligand-regulated integral membrane scaffolding protein enriched in the ER of cancer cells. PD-L1 is an integral membrane glycoprotein that is translated into the ER and processed through the cellular secretory pathway. At the cell surface, PD-L1 is an immune …

Using Rna-Sequencing To Explore Mechanistic Markers, New Therapeutics, And Immune Imbalance: A Study Of Cancer And Autoimmunity Through The Lens Of Triple Negative Breast Cancer, Systemic Lupus Erythematosus, And B-Cell Non-Hodgkin's Lymphoma, Naomi Lydia Rapier-Sharman

Theses and Dissertations

Cancer and autoimmune diseases both impose a substantial healthcare burden on the US and world populations. In 2016, there were over 17 million cases of cancer, leading to nearly nine million deaths. Additionally, autoimmune diseases cause substantial mortality and morbidity and are present in 3-5% of the general population. Despite the increased attention scientists now give diseases that are impacted by immune imbalance, we have yet to find regimens to treat the core cause(s) of tissue dysfunction without drastically decreasing the quality of life for many patients with either cancer or autoimmune disease. For instance, anti-CD19 Chimeric Antigen Receptor (CAR) …

A Unique Metal Object From Tiberias (Pp. 173–181), Myriam Rosen-Ayalon

'Atiqot

An uncommon metal artifact (a stand?) was uncovered in the course of public works in Tiberias. The object is an open cylinder, made of sheet-metal, perhaps bronze. Both the outer and inner surfaces are adorned with a band of painted decoration: the exterior surface depicts a scene of human figures, while the interior one is a beautiful inscription in kufic script. No parallels to Islamic painted metalwork have been yet discovered; however, our painted object should perhaps be seen within the wider context of the art of painting under the Fatimids.

Inhibition Of Vascular Smooth Muscle Cell Perk/Atf4 Er Stress Signaling Protects Against Abdominal Aortic Aneurysms, Brennan Callow, Xiaobing He, Nicholas Juriga, Kevin D Mangum, Amrita Joshi, Andrea Obi, Dianna M Milewicz, Mary X O'Riordan, Johann Gudjonsson, Katherine Gallagher, Frank M Davis

Faculty, Staff and Student Publications

Abdominal aortic aneurysms (AAA) are a life-threatening cardiovascular disease for which there is a lack of effective therapy preventing aortic rupture. During AAA formation, pathological vascular remodeling is driven by vascular smooth muscle cell (VSMC) dysfunction and apoptosis, for which the mechanisms regulating loss of VSMCs within the aortic wall remain poorly defined. Using single-cell RNA-Seq of human AAA tissues, we identified increased activation of the endoplasmic reticulum stress response pathway, PERK/eIF2α/ATF4, in aortic VSMCs resulting in upregulation of an apoptotic cellular response. Mechanistically, we reported that aberrant TNF-α activity within the aortic wall induces VSMC ATF4 activation through the …

Optimized Methods To Quantify Tumor Treating Fields (Ttfields)-Induced Permeabilization Of Glioblastoma Cell Membranes, Melisa Martinez-Paniagua, Sabbir Khan, Nikita W Henning, Sri Vaishnavi Konagalla, Chirag B Patel

Faculty, Staff and Student Publications

Glioblastoma (GBM) is a lethal primary brain cancer with a 5.6% five-year survival rate. Tumor treating fields (TTFields) are alternating low-intensity electric fields that have demonstrated a GBM patient survival benefit. We previously reported that 0.5-24 h of TTFields exposure resulted in an increased uptake of FITC-dextran fluorescent probes (4-20 kDa) in human GBM cells. However, this approach, in which a fluorescence plate-based detector is used to evaluate cells attached to glass coverslips, cannot distinguish FITC-dextran uptake in live vs. dead cells. The goal of the study was to report the optimization and validation of two independent methods to quantify …

Failure Of The Farm Bill Process In 2023—A Perspective From Social Media Activity, Roman Keeney, Nicole Olynk Widmar, Austin Berenda

Department of Agricultural Economics Faculty Publications

In September 2023, the current farm bill was allowed to expire. This marked the fourth consecutive farm bill to see its authorization lapse before replacement legislation was signed into law. The failure in 2023 is notable as significant trade and covid shocks revealed needed reforms in farm and food safety nets. We develop a unique online and social media dataset and metrics to examine 2023 online activity to understand drivers of online farm bill discussion and implications for the future of the traditional farm bill political coalition. These findings echo the increasing concern about future farm bills amid a broadening …
