Lithological Modeling And Aquifer Characterization Of The Coastal Lowlands Aquifer System In Texas, Emmanuel Egyin Hayford

LSU Master's Theses

The Texas Coastal Lowlands Aquifer System (CLAS) is a crucial water resource for the Gulf Coast, serving millions through municipal, agricultural, and industrial supplies. However, its sustainability is increasingly threatened by factors such as population growth, saltwater intrusion, land subsidence, and climate change. A significant limitation is the absence of a comprehensive, data-rich, three-dimensional lithologic model that accurately represents the intricate structure and geometry of the aquifer. Existing models are overly simplistic, treating the hydrogeologic unit as laterally uniform and failing to capture its true hydrogeologic complexity. This study addresses this gap by developing the first high-resolution 3D lithologic model …

Uav Remote Sensing For Assessment Of Conservative Management Practices In Maize-Soybean Cropping System, Aakriti Poudel

LSU Master's Theses

Sustainable agriculture practices promote cover cropping, which enhances nutrient management and impacts subsequent crop productivity in field crop rotations. Precision agriculture technology, particularly Unmanned Aerial Vehicle (UAV) remote sensing, enables a detailed evaluation of crop management. The studies were conducted in a maize-soybean rotation system with winter cover cropping and fallow management. The maize experiment investigated the effect of nitrogen application rates and cover cropping, using UAV-derived Normalized Difference Red-Edge (NDRE) to monitor crop performance. NDRE effectively captured the N response and the effect of cover cropping across growth stages, particularly during mid-season (55-81 DAP), where it showed a strong …

Effects Of Code Scaffolding In Increasing Student Confidence In Programming Cryptography, John Denny

LSU Master's Theses

Cryptography is essential for secure communications, and new threats require more students willing to program and interact with cryptographic systems. Previous research is focused on tools for teaching these systems at a high level, teaching through attacks against these systems, and proper use of these systems in software development. In this paper, we seek to design a workshop to use scaffolded Python code to teach how these cryp- tographic systems are designed. We explore the use of code scaffolding for students to program an example implementation of the McEliece crypto- graphic system to build confidence in working with these systems. …

Integrating Cereal Rye Cover Crop And Herbicide Programs To Manage Glyphosate-Resistant Italian Ryegrass In The Midsouth, Bhupesh K. Dhaka

LSU Master's Theses

Glyphosate-resistant (GR) Italian ryegrass (Lolium perenne ssp. multiflorum) has become an economically significant weed management challenge in Louisiana row crop production systems. The problem is further exacerbated by the occurrence of biotypes with resistance to acetyl-CoA carboxylase (ACCase) and acetolactate synthase (ALS) inhibitors—herbicide sites of action (SOAs) commonly used for ryegrass control in soybean (Glycine max) and cotton (Gossypium). Field, greenhouse, and laboratory experiments were conducted during the 2023–2024 and 2024–2025 growing seasons at the LSU AgCenter Northeast Research Station in St. Joseph, LA, and at the LSU AgCenter Weed Science facilities in Baton …

Examining Private Landowner And Stakeholder Attitudes, Perceptions, And Knowledge Of Prescribed Fire In Louisiana, Chloe E. Crawford

LSU Master's Theses

Periodic fire was a primary driver of ecosystems across the Southeastern United States for millennia; however, fire suppression policies have become pervasive in the United States and led to increased fuel loads in forests as well as reduced biodiversity and reduced disease resilience. Prescribed fire presents a risk mitigation strategy and land management tool whereby practitioners can apply fire to the landscape in a controlled manner, thus reaping the benefits of fire while minimizing the risks associated with fire. Land in Louisiana is primarily privately managed and owned, so state-level conservation goals cannot be met without private landowner participation. As …

2020-Current year OA Pubs

Extracranial metastasis of IDH-wildtype glioblastoma is very rare and poorly understood at the molecular level. We report a case of FGFR3::TACC3 fusion IDH-wildtype glioblastoma in a 61-year-old male, whose preoperative blood sample showed highly aberrant cfDNA fragmentation patterns, which could be suggestive of early systemic dissemination, undetected by standard-of-care imaging of his body. Eleven months post-resection and adjuvant therapy, he developed widespread extracranial metastases. Comprehensive molecular profiling of matched primary and metastatic tumors revealed broadly conserved genomic, transcriptomic, and copy number landscapes, with the metastasis harboring an additional ERCC6 deletion and enriched expression of receptor tyrosine kinase signaling genes. These …

Muscle Fatigue Arising Intrinsically From Sur2- But Not Kir6.1-Dependent Gain-Of-Function In Cantu Syndrome Mice, Rosa Scala, Maya Mukadam, Yuezhou Chen, Courtney Frazier, Nathaniel W York, Robert C Tryon, Gretchen A Meyer, Colin G Nichols

2020-Current year OA Pubs

Cantu syndrome (CS) is a rare disease caused by gain-of-function (GOF) mutations of Kir6.1 or SUR2 subunits of ATP-sensitive potassium (KATP) channels. CS patients with SUR2 and Kir6.1 variants display a similar constellation of symptoms, including muscle weakness and fatigue. The effects of CS mutations on skeletal muscle KATP channels, and any consequent direct effects on contractility, are currently unclear. Here, we used two knock-in mouse models of CS, respectively, carrying GOF mutations Kir6.1[V65M] or SUR2[A478V], to assess KATP channel properties and contractility in isolated fast-twitch extensor digitorum longus (EDL) and slow-twitch soleus (SOL) muscles. Electrophysiological recordings in isolated myofibers …

Pip2-Driven Cytoplasmic Domain Motions Are Coupled To Kir2 Channel Gating, Eva-Maria Zangerl-Plessl, Anna Stary-Weinzinger, Colin G Nichols, Sun-Joo Lee

2020-Current year OA Pubs

Inwardly rectifying potassium (Kir) channel activity is important in the control of membrane potentials in both excitable and non-excitable cells and is regulated through various ligands, including specific membrane lipids. Phosphatidyl-4,5-bisphosphate (PIP2) is required for activity of all Kir channels, binding to the cytoplasmic domain in a compact conformation tightly tethered to the transmembrane domain. Most Kir2 channel structures determined in complex with PIP2 molecules are nevertheless in a closed state, requiring additional conformational changes for channel opening. We have carried out full atomistic MD simulations, which indicate PIP2-dependent conformational changes that are coupled to opening and closing of the …

METHODS: We performed a retrospective cohort study of patients with stage I NSCLC treated with lung resection at Veterans Health Administration (VHA) facilities between 2006 and 2016. The VHA provides thoracic surgery at approximately 100 facilities, whereas lung SBRT is currently available at approximately 20 facilities. We …

A Clinical Practice Guideline For The Management Of Pregnancy Alloimmunized To Red Blood Cell Antigens, Kenneth J Moise, Jay Malone, Et Al.

2020-Current year OA Pubs

IMPORTANCE: Red blood cell alloimmunization is typically associated with the transplacental transfer of incompatible fetal red blood cells into maternal circulation. Subsequent pregnancies can be affected by fetal anemia, hydrops fetalis, and perinatal death. Most cases of Rhesus D (RhD) alloimmunization due to pregnancy can be prevented by the proper administration of Rhesus immune globulin. However, an emerging practice of using low-titer, O, RhD-positive whole blood (LTOWB) in cases of life-threatening hemorrhage has the potential to increase the exposure of the female population to a new source of incompatible red blood cells.

OBJECTIVE: To establish recommendations for the management of …

Overexpression Of The Signaling Coordinator Gab2 Can Play An Important Role In Acute Myeloid Leukemia Progression, Michael H. Kramer, Stephanie N. Richardson, Yang Li, Tiankai Yin, Nichole M. Helton, Daniel R. George, Michelle Cai, Sai Mukund Ramakrishnan, Casey Ds Katerndahl, Christopher A. Miller, Timothy J. Ley

2020-Current year OA Pubs

Mutations that initiate acute myeloid leukemia (AML) can cause clonal expansion without transformation (clonal hematopoiesis). Cooperating mutations, usually in signaling genes, are needed to cause overt disease, but these may require a specific fitness state to be tolerated. Here, we show that nearly all AMLs arising in a mouse model expressing 2 common AML-initiating mutations (Dnmt3aR878H and Npm1cA) acquired a single copy amplification of chromosome 7 (chr7), followed by activating mutations in signaling genes. We show that overexpression of a single gene on chr7 (Gab2, which coordinates signaling pathways) was tolerated in the presence of the Npm1cA mutation, could accelerate …
