Development Of Functional Markers For Resistance To Smut And Identification Of Genes Differentially Expressed In Response To Brown Rust In Sugarcane, Jose David Cortes

LSU Doctoral Dissertations

Smut, caused by Sporisorium scitamineum and brown rust, caused by Puccinia melanocephala, are two of the most important diseases that affect sugarcane production in Louisiana and worldwide. Smut continues to cause losses in the breeding program in Louisiana. Therefore, a QTL analysis was conducted to identify molecular markers associated with resistance in F₁ progeny (162) of a biparental cross between susceptible cultivar L 99-233 and resistant HoCP 96-540. Using 1,574 single-dose SNP markers, a total of 253 linkage groups (LG) were obtained with a genome coverage of 24,580.15 cM. Six QTLs were localized on five LGs. The highest …

The Spectral Sensitivity Of Human Circadian Phase Resetting And Melatonin Suppression To Light Changes Dynamically With Light Duration, Melissa A. St Hilaire, María L. Ámundadóttir, Shadab A. Rahman, Shantha M. W. Rajaratnam, Melanie Rüger, George C. Brainard, Charles A. Czeisler, Marilyne Andersen, Joshua J. Gooley, Steven W. Lockley

Department of Neurology Faculty Papers

Human circadian, neuroendocrine, and neurobehavioral responses to light are mediated primarily by melanopsin-containing intrinsically-photosensitive retinal ganglion cells (ipRGCs) but they also receive input from visual photoreceptors. Relative photoreceptor contributions are irradiance- and duration-dependent but results for long-duration light exposures are limited. We constructed irradiance-response curves and action spectra for melatonin suppression and circadian resetting responses in participants exposed to 6.5-h monochromatic 420, 460, 480, 507, 555, or 620 nm light exposures initiated near the onset of nocturnal melatonin secretion. Melatonin suppression and phase resetting action spectra were best fit by a single-opsin template with lambda_max at 481 and 483 …

A New Gtseq Resource To Facilitate Multijurisdictional Research And Management Of Walleye Sander Vitreus, Peter T. Euclide, Wesley A. Larson, Matthew Bootsma, Loren M. Miller, Kim T. Scribner, Wendylee Stott, Chris C. Wilson, Emily K. Latch

Purdue University Libraries Open Access Publishing Fund

Conservation and management professionals often work across jurisdictional boundaries to identify broad ecological patterns. These collaborations help to protect populations whose distributions span political borders. One common limitation to multijurisdictional collaboration is consistency in data recording and reporting. This limitation can impact genetic research, which relies on data about specific markers in an organism's genome. Incomplete overlap of markers between separate studies can prevent direct comparisons of results. Standardized marker panels can reduce the impact of this issue and provide a common starting place for new research. Genotyping-in-thousands (GTSeq) is one approach used to create standardized marker panels for nonmodel …

Regional Airline Pilot Profession Post Colgan 3407, Brett Maas

Honors Theses

Colgan Air Flight 3407 was a devastating aircraft accident that resulted in the loss of 50 lives (Beresnevicius, 2019). Multiple factors played into the accident, such as pilot credentials, pilot experience, weather, and fatigue. As a result of the accident, the regional airline pilot profession was changed entirely. Changes that spurred because of the accident were both regulatory and compensatory in nature. Regulatory changes include the introduction of the Pilot Records Database (online database that stores pilot training histories), increased flight experience requirements to become a First Officer at an air carrier, and the introduction of proactive rest rules with …

The direct medical costs and indirect social and economic costs of dementia are burdensome to society, and by 2030 it is projected to cost more than $2.8 TRILLION dollars worldwide. African Americans are two to four times more likely to be diagnosed with dementia than White Americans; and more likely to rely on informal care from family and friends. African …

Single-Shot, Ultrafast, Multi-Frame X-Ray Imaging Of Defect-Bearing Ablator Materials In Extreme Conditions, Daniel S. Hodge

Theses and Dissertations

Characterization of the dynamic behavior of defect-bearing ablator materials subjected to extreme conditions is essential in advancing fusion energy as an reliable and abundant energy source. By understanding how materials evolve spatially and temporally we can minimize hydrodynamic instabilities, which are major contributing factors to energy yield degradation in inertial confinement fusion (ICF) experiments. In this thesis we demonstrate the capabilities of an ultrafast x-ray imaging (UXI) detector, the Icarus V2, where we capture multiple frames of single void-bearing sample compressed by a high-intensity laser shockwave. Using the Matter in Extreme Conditions (MEC) instrument at the Linac Coherent Light Source …

Delivering Explicit Math Instruction Through Point-Of-View Video Modeling To Elementary Students With Autism Spectrum Disorder, Patsy Mccray Gibbs

Theses and Dissertations

There is significant literature demonstrating the effectiveness of video modeling for teaching skills to students with disabilities. Still, much less is known about how video modeling, particularly point-of-view video modeling (POV-VM), might be applied to teach academic skills to children with an autism spectrum disorder. This multiple probe single-case design study used explicit instruction techniques to teach multiplication, division, and fraction skills to two elementary-aged students with an autism spectrum disorder. A visual analysis of the data showed that POV-VM using explicit techniques to deliver the videos is an effective intervention for autistic students This research study adds to the …

Decision-Based Learning As A Tool For Teaching Statistics In A Peruvian University, Gloria Mora Barba

Theses and Dissertations

Many students find that learning statistics is difficult, especially novice learners first taking statistical classes. Instructors also struggle to teach statistics due to many challenges, such as students' misconceptions, lack of math skills, negative attitudes, and deficient instructional methods. A new pedagogical approach called Decision-Based Learning (DBL) has been developed to help instructors and students overcome these challenges. A group of Peruvian university professors in 2018 and 2019 were trained to use DBL. However, limited studies have explored DBL instructors' and students' experiences using DBL in Peru. The aim of this qualitative research study is to deeply understand the experiences …

Quantifying Shape Variation In An Antisymmetrical Trait In Xenophallus Umbratilis, Mary-Elise Johnson Nielsen

Theses and Dissertations

Antisymmetry is a striking, yet puzzling form of biological asymmetry. The livebearing fish Xenophallus umbratilis exhibits antisymmetry in the male intromittent organ and provides a system that is well-suited for studying the nature of variation in antisymmetrical traits. Using geometric morphometrics, I test the hypothesis that because the gonopodium is critical to fitness there will not be significant differences in gonopodium shape between the two gonopodial morphs in this species. My results are consistent with this prediction, though I found that gonopodium shape did differ with gonopodium size.

Gabapentin Disrupts Binding Of Perlecan To The Α 2Δ1 Voltage Sensitive Calcium Channel Subunit And Impairs Skeletal Mechanosensation, Perla C Reyes Fernandez, Christian S Wright, Adrianna N Masterson, Xin Yi, Tristen V Tellman, Andrei Bonteanu, Katie Rust, Megan L Noonan, Kenneth E White, Karl J Lewis, Uma Sankar, Julia M Hum, Gregory Bix, Danielle Wu, Alexander G Robling, Rajesh Sardar, Mary C Farach-Carson, William R Thompson

Faculty, Staff and Student Publications

Our understanding of how osteocytes, the principal mechanosensors within bone, sense and perceive force remains unclear. Previous work identified "tethering elements" (TEs) spanning the pericellular space of osteocytes and transmitting mechanical information into biochemical signals. While we identified the heparan sulfate proteoglycan perlecan (PLN) as a component of these TEs, PLN must attach to the cell surface to induce biochemical responses. As voltage-sensitive calcium channels (VSCCs) are critical for bone mechanotransduction, we hypothesized that PLN binds the extracellular α2δ1 subunit of VSCCs to couple the bone matrix to the osteocyte membrane. Here, we showed co-localization of PLN and α2δ1 along …

Background: Brugada syndrome (BrS) is a severe inherited arrhythmia syndrome that can be unmasked by fever.

Methods: A multicentre clinical analysis was performed in 261 patients diagnosed with fever-induced BrS, including 198 (75.9%) and 27 (10.3%) patients who received next-generation genetic sequencing and epicardial arrhythmogenic substrate (AS) mapping, respectively.

Findings: In fever-induced BrS patients, pathogenic or likely pathogenic (P/LP) SCN5A variant carriers developed fever-induced BrS at a younger age, and more often in females and those of Caucasian descent. They exhibited significant electrophysical abnormalities, including a larger epicardial AS area, and more prolonged abnormal epicardial electrograms. During a median follow-up …

A Phenomenological Study Of Collegiate Recovery Leadership, Marni Goldberg

Teacher Education, Educational Leadership & Policy ETDs

Due to the marginalized status of the population they serve, collegiate recovery programs are generally underfunded and employ one staff member who typically holds other job tasks in addition to those of collegiate recovery leader. The consequence of the varied nature by which collegiate recovery programs are founded and implemented is inconsistency, which can threaten the longevity of the field. The purpose of this phenomenological study was to elicit information directly from collegiate recovery leaders to gain a deeper understanding of their lived experience, in order to determine how to best serve and support higher education students in recovery from …

Heterogeneous Strain Distribution & The Effects Of High Frequency Climate Change On The Evolution Of Early-Stage Rift Systems: Case Studies From Lakes Tanganyika And Malawi (Nyasa), East Africa, Lachlan Wright

Dissertations - ALL

The break-up of the earth’s crust through the formation of continental rift basins is a fundamental aspect of plate-tectonics and the first step that ultimately leads to plate-spreading, new continent formation, and the creation of ocean basins. Within continental rifts, processes associated with extensional faulting drive uplift and subsidence of the landscapes forming rift valleys, and climatically influenced processes act upon these transient landscapes, erode them, modify relief, and produce sediments that infill the rift valleys creating the stratigraphic record. Continental rifts are highly sensitive to the interplay between extensional faulting, sedimentary processes, and climate change, and variations in the …

A Robust Random Forest Prediction Model For Mother-To-Child Hiv Transmission Based On Individual Medical History, Rebecca Chaula

Investigating The Support For Agility In Developing Government Software Systems: A Case Of Three East African Countries, Leonard Peter Binamungu

Tanzania Journal of Engineering and Technology (TJET)

Agile Software Development Methods support an iterative and incremental way of developing software systems while responding to change by prioritising various aspects at different times. This differs from traditional sequential methods like Waterfall, in which one software development stage has to be completed before starting the next stage. To produce software systems that meet the requirements of their institutions, several governments in Africa have issued standards and guidelines to be followed during the development of government software systems. Such standards and guidelines specify the specific activities and deliverables for each stage of software development. While well-intentioned, such guidelines and standards …

An Investigation Of Spirituality In Person-Centered Planning For Adults With Intellectual/Developmental Disabilities, Holly F. Pedersen, Jolynn Webster

Journal of Sustainable Social Impact

While research identifies spirituality and inclusion in a community of faith as key factors contributing to quality of life for many individuals in our society, people with disabilities are often not able to access this aspect of everyday life if they wish. To change this, four groups must come together: (1) individuals with disabilities; (2) faith communities; (3) families of people with disabilities; and (4) support service providers. Current research describes the efforts of faith communities and people with disabilities and their families relative to spiritual inclusion; however, little is known about how support service systems are addressing this topic. …

Examining Teaching Practices That Increase Student Mathematical Achievement, Jonah P. Zimmerman

Masters Projects

The current data in the United States surrounding mathematics shows that there are issues that must be addressed with teaching and learning math in the K-12 setting. In the perfect world, all students would meet grade level expectations in math prior to moving to another grade; however, this is not what is taking place. Students are not meeting proficiency, and as a result teachers and students alike are not gaining confidence in teaching/learning mathematics. This project looks at the Math Workshop Model as being one alternative to the more traditional teaching practices that are used today in the ABC School …

Contributions Of Semantic And Phonological Working Memory To Narrative Language Independent Of Single Word Production: Evidence From Acute Stroke, Rachel Zahn, Tatiana T Schnur, Randi C Martin

Faculty, Staff and Student Publications

Neuropsychological case studies have provided evidence that individuals with semantic, but not phonological, working memory (WM) deficits have difficulty producing phrases containing several content words. These findings supported the claim of a phrasal scope of planning at the grammatical formulation stage of production, where semantic WM supports the maintenance of lexical-semantic representations as they are inserted into slots in phrasal constituents. Recent narrative production results for individuals at the acute stage of stroke supported the role for semantic WM in phrasal elaboration while suggesting a role for phonological WM at a subsequent phonological encoding stage in supporting fluent, rapid speech. …

Trib3 Mediates Fibroblast Activation And Fibrosis Though Interaction With Atf4 In Ipf, Lan Wang, Wenyu Zhao, Cong Xia, Zhongzheng Li, Weiming Zhao, Kai Xu, Ningdan Wang, Hui Lian, Ivan O Rosas, Guoying Yu

Faculty, Staff and Students Publications

Idiopathic pulmonary fibrosis (IPF) is a fatal interstitial lung disease characterized by fibroblast activation, excessive deposition of extracellular matrix, and progressive scarring; the pathogenesis remains elusive. The present study explored the role of Tribbles pseudokinase 3 (TRIB3), a well-known stress and metabolic sensor, in IPF. TRIB3 is down-regulated in the lungs of IPF patients in comparison to control subjects. Deficiency of TRIB3 markedly inhibited A549 epithelial cells’ proliferation and migration, significantly reducing wound healing. Conversely, overexpression of TRIB3 promoted A549 cell proliferation and transmigration while it inhibited its apoptosis. Meanwhile, overexpressed TRIB3 inhibited fibroblast activation and decreased ECM …
