The genus Phyllachora contains numerous obligate fungal parasites that produce raised, melanized structures called stromata on their plant hosts referred to as tar spot. Members of this genus are known to infect many grass species but generally do not cause significant damage or defoliation, with the exception of P. maydis which has emerged as an important pathogen of maize throughout the Americas, but the origin of this pathogen remains unknown. To date, species designations for Phyllachora have been based on host associations and morphology, and most species are assumed to be host specific. We assessed the sequence diversity of 186 …

A Nondestructive Method Of Calculating The Wing Area Of Insects, Kexin Yu, Gadi V.P. Reddy, Julian Schrader, Xuchen Guo, Yirong Li, Yabing Jiao, Peijian Shi

Faculty Publications

Most insects engage in winged flight. Wing loading, that is, the ratio of body mass to total wing area, has been demonstrated to reflect flight maneuverability. High maneuverability is an important survival trait, allowing insects to escape natural enemies and to compete for mates. In some ecological field experiments, there is a need to calculate the wing area of insects without killing them. However, fast, nondestructive estimation of wing area for insects is not available based on past work. The Montgomery equation (ME), which assumes a proportional relationship between leaf area and the product of leaf length and width, is …

Resistance Allele Frequency To Cry1ab And Vip3aa20 In Helicoverpa Zea (Boddie) (Lepidoptera: Noctuidae) In Louisiana And Three Other Southeastern U.S. States, Shucong Lin, Isaac Oyediran, Ying Niu, Sebe Brown, Don Cook, Xinzhi Ni, Yan Zhang, Francis P.F. Reay-Jones, Jeng Shong Chen, Zhimou Wen, Marcelo Dimase, Fangneng Huang

Faculty Publications

The corn earworm/bollworm, Helicoverpa zea (Boddie), is a pest species that is targeted by both Bacillus thuringiensis (Bt) maize and cotton in the United States. Cry1Ab and Vip3Aa20 are two common Bt toxins that are expressed in transgenic maize. The objective of this study was to determine the resistance allele frequency (RAF) to Cry1Ab and Vip3Aa20 in H. zea populations that were collected during 2018 and 2019 from four southeastern U.S. states: Louisiana, Mississippi, Georgia, and South Carolina. By using a group-mating approach, 104 F2 iso-lines of H. zea were established from field collections with most iso-lines (85) from Louisiana. …

Do Mobile Consumers Homogenize The Distribution Of Resources In Stream Food Webs? A Test With Overlapping Fish And Mussel Aggregations, Caryn C. Vaughn, Thomas B. Parr, Traci P. Dubose, Kiza K. Gates, Garrett W. Hopper, Keith B. Gido

Faculty Publications

In streams, unionoid mussels and fish form aggregations that exert bottom-up and top-down effects on food webs, but the magnitude and spatial extent of their effects are controlled by species traits. Sedentary mussels live burrowed in the sediment in patchily distributed dense aggregations (mussel beds) where they filter seston and provide a local, relatively constant nutrient subsidy. In contrast, fish move on and off mussel beds, and thus comprise a transient nutrient subsidy. We asked how overlap between fish and mussels influences nutrient recycling and resource distribution in streams. We conducted an 8-week study in experimental streams where we created …

Role Of Akr1b10 And Akr1b8 In The Pathogenesis Of Non-Alcoholic Steatohepatitis (Nash) In Mouse, Sangam Rajak, Pratima Gupta, Baby Anjum, Sana Raza, Archana Tewari, Sujoy Ghosh, Madhulika Tripathi, Brijesh K. Singh, Rohit A. Sinha

Division of Basic Science Faculty Publications

Non-alcoholic steatohepatitis (NASH) is a clinically important spectrum of non-alcoholic fatty liver disease (NAFLD) in humans. NASH is a stage of NAFLD progression wherein liver steatosis accompanies inflammation and pro-fibrotic events. Presently, there are no approved drugs for NASH, which has become a leading cause of liver transplant worldwide. To discover novel drug targets for NASH, we analyzed a human transcriptomic NASH dataset and found Aldo-keto reductase family 1 member B10 (AKR1B10) as a significantly upregulated gene in livers of human NASH patients. Similarly murine Akr1b10 and Aldo-keto reductase family 1 member B8 (Akr1b8) gene, which is a murine ortholog …

Exercise training beneficially moderates the effects of vascular aging. This study compared the efficacy of Peripheral Remodeling through Intermittent Muscular Exercise (PRIME), a novel training regimen, versus aerobic training on hemodynamic profiles in participants ≥70 years at risk for losing functional independence. Seventy-five participants (52 females, age: 76 ± 5 years) were assessed for hemodynamic and vascular function at baseline, after 4 weeks of either PRIME or aerobic training (Phase 1) and again after a further 8 weeks of aerobic and resistance training (Phase 2). Data were analyzed using 2 × 2 repeated-measures analysis of variance models on the change …

Clinical Research Faculty Publications

Objective: The aim of this study was to test the hypothesis that ephedrine + caffeine (EC) reduces the fall in resting energy expenditure (REE) following bariatric surgery. Methods: This 32-week, randomized, double-blinded, placebo-controlled trial included 142 patients who underwent Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) surgery. Participants were randomized to either EC or placebo for 27 weeks, beginning 5 weeks post surgery. The primary end points were change in REE (measured), percentage of predicted REE ([measured REE/Harris-Benedict equation-predicted REE] × 100), and body composition. Secondary outcomes included change in percentage of weight. Adverse events (AEs) were recorded. Results: …

Financial Challenges And Capacity Among African Refugees In The Southern Usa: A Study Of Socio-Demographic Differences, Njeri Kagotho, Jennifer Scott, Mckenzie M. Ketchum, Youn Kyoung Kim, Arati Maleku, Younghee Lim

Faculty Publications

Refugees’ successful integration into US society requires adaptation to economic, financial and social norms. Despite the importance of considering financial challenges (financial stress and financial anxiety) and financial capacity (financial literacy and financial self-efficacy) in reaching personal financial goals, literature examining the relationship between financial challenges and capacity—critical in refugee resettlement and integration—is sparse and fragmented. This study explored financial challenges and capacity amongst resettled African refugees (N ¼ 130) in the southern USA using data from a larger community-based participatory research study that used a mixed-methods approach. We explored socio-demographic differences in financial stress, financial anxiety, financial literacy and …

Exercise As A Moderator Of Persistent Neuroendocrine Symptoms Of Covid-19, Candida J. Rebello, Christopher L. Axelrod, Charles F. Reynolds, Frank L. Greenway, John P. Kirwan

Division of Basic Science Faculty Publications

Precipitated by chronic psychological stress, immune system dysregulation, and a hyperinflammatory state, the sequelae of postacute COVID-19 (long COVID) include depression and new-onset diabetes. We hypothesize that exercise counters the neuropsychiatric and endocrine sequelae of long COVID by inducing the release of circulating factors that mediate the anti-inflammatory response, support brain homeostasis, and increase insulin sensitivity.

Constraints On Dark Photon Dark Matter Using Data From Ligo's And Virgo's Third Observing Run, R. Abbott

Faculty Publications

We present a search for dark photon dark matter that could couple to gravitational-wave interferometers using data from Advanced LIGO and Virgo's third observing run. To perform this analysis, we use two methods, one based on cross-correlation of the strain channels in the two nearly aligned LIGO detectors, and one that looks for excess power in the strain channels of the LIGO and Virgo detectors. The excess power method optimizes the Fourier transform coherence time as a function of frequency, to account for the expected signal width due to Doppler modulations. We do not find any evidence of dark photon …

Are Long-Period Exoplants Around Cool Stars More Common Than We Thought?, Emily Jane Safron

LSU Doctoral Dissertations

The Kepler mission has been the catalyst for discovery of nearly 5,000 confirmed and candidate exoplanets. The majority of these candidates orbit Sun-like stars, and have orbital periods comparable to or shorter than that of the Earth, due to the selection bias inherent in the transit method and the limitations of automated transit search algorithms. We aim to develop a richer understanding of the population of exoplanets around the lowest-mass stars, the M spectral type. We are particularly interested in exoplanets with long orbital periods, which are difficult or impossible to find using standard transit search algorithms. In our study, …

Pharmakon In The Firelands: Connecting Historical Discourses And Small-Town Social Contexts With Substance Use Experience, Andrew Robert Burns

LSU Doctoral Dissertations

The ongoing increase in opioid and polysubstance-related overdoses and mortality in United States coincides with a shift in the ways substance use is understood. Once almost exclusively treated as a criminal problem, substance use, and overdose is increasingly viewed in terms of public health and from an urban to rural issue. The discourse surrounding the use of psychoactive substances largely omits the voices of the very people who use them. Likewise, the social context of small towns, at once not quite rural nor entirely urban, is generally given little consideration. To address these gaps in the research, I conduct two …

Structural Problems Of Latin American Cities 450 Years After Caracas’ Foundation, Fabio Capra-Ribeiro

Faculty Publications

Latin American cities face many problems that compromise them from different angles such as lack of infrastructure, government fragmentation, and environmental degradation. At the same time, each city tries to come up with its own solutions, but there are so many difficulties that in many cases it is difficult to keep attention and efforts focused on all these directions. For these reasons, this research aims to define some of the most common problems faced by cities in Latin America. Disseminating these similarities could help to face those problems, since, if local governments recognize that they face the same situations as …

The Application Of Physics Informed Neural Networks To Compositional Modeling, Thelma A. Ihunde

LSU Master's Theses

Compositional modeling is essential when simulating processes involving significant changes in reservoir fluid composition. It is computationally expensive because we typically need to predict the states and properties of multicomponent fluid mixtures at several different points in space and time. To speed up this process, several researchers have used machine learning algorithms to train deep learning (DL) models on data from the rigorous phase-equilibrium (flash) calculations. However, one shortcoming of the DL models is that there is no explicit consideration for the governing physics. So, there is no guarantee that the model predictions will honor the thermodynamical constraints of phase …

Maintenance Cost Minimization Models For Offshore Wind Farms: A Systematic And Critical Review, Md Imran Hasan Tusar, Bhaba R. Sarker

Faculty Publications

Feasible and sustainable source of power is a burning question nowadays. The offshore wind farms can be a solution to power generation problem, but it is relatively more expensive. Its installation cost is more than twice of its similar size onshore counterpart. The cost that matters most is the operations and maintenance (O&M) cost. Expensive and sophisticated transfer vehicles as well as highly skilled technicians are needed to conduct O&M activities, which results in a remarkably higher O&M cost for an offshore wind farm project. Few researchers proposed some strategies that could resolve the problem nicely, although there is no …

The Design, Construction, And Testing Of A Recombinant Dna Vaccine For Brucella Abortus And Brucella Melitensis, Stephanie Lynn Korle

LSU Doctoral Dissertations

Brucella spp. are a bacterium that cause brucellosis, a zoonotic disease, which is commonly seen in cattle, sheep, goats, swine, and canines. Brucellosis is a problem worldwide, although it is eradicated in some countries (Garin-Bastuji et al. 1998). The reason for designing recombinant DNA (rDNA) vaccines opposed to utilizing the live-attenuated vaccines on the market is that they cannot be given to pregnant animals without potentially causing abortion, while an rDNA vaccine should be safe for pregnant animals since it does not contain viable bacteria. Also, there are no serological tests that can accurately distinguish between an animal vaccinated …
