Previous studies have reported that the corn earworm/bollworm, Helicoverpa zea (Boddie), has developed field resistance to pyramided Bacillus thuringiensis (Bt) Cry1A/Cry2A maize and cotton in certain areas of the southeastern United States. The objective of the current study was to determine the current status and distribution of the resistance to Cry1A.105 and Cry2Ab2 in H. zea. In the study, 31 H. zea populations were collected from major maize planting areas across seven southeastern states of the United States during 2018 and 2019 and assayed against the two Bt proteins. Diet over-lay bioassays showed that most of the populations collected during …

Reciprocal Control Of Obesity And Anxiety–Depressive Disorder Via A Gaba And Serotonin Neural Circuit, Guobin Xia, Yong Han, Fantao Meng, Yanlin He, Dollada Srisai, Monica Farias, Minghao Dang, Richard D. Palmiter, Yong Xu, Qi Wu

Division of Basic Science Faculty Publications

The high comorbidity between obesity and mental disorders, such as depression and anxiety, often exacerbates metabolic and neurological symptoms significantly. However, neural mechanisms that underlie reciprocal control of feeding and mental states are largely elusive. Here we report that melanocortin 4 receptor (MC4R) neurons located in the dorsal bed nucleus of the stria terminus (dBNST) engage in the regulation of mentally associated weight gain by receiving GABAergic projections from hypothalamic AgRP neurons onto α5-containing GABAA receptors and serotonergic afferents onto 5-HT3 receptors. Chronic treatment with a high-fat diet (HFD) significantly blunts the hyperexcitability of AgRP neurons in response to not …

Factors Protecting Against A Decline In Physical Activity During The Covid-19 Pandemic, S. Nicole Fearnbach, Emily W. Flanagan, Christoph Höchsmann, Robbie A. Beyl, Abby D. Altazan, Corby K. Martin, Leanne M. Redman

Clinical Research Faculty Publications

Purpose The spread of COVID-19 and the associated stay-At-home orders and shutdowns of gyms and fitness centers have drastically influenced health behaviors leading to widespread reductions in physical activity (PA). The recent Call to Action from the American College of Sports Medicine has promoted "innovative strategies to promote PA during the COVID-19 pandemic."We aimed to identify individual-level factors that protected against declines in PA levels amid the COVID-19 restrictions. Methods We used the Pennington Biomedical COVID-19 Health Behaviors Survey for our analyses and used mixed-effect linear and generalized linear models to estimate the effects of individual-level factors on changes in …

Exercise Is Key To Sustaining Metabolic Gains After Bariatric Surgery, Bruno Gualano, John P. Kirwan, Hamilton Roschel

Division of Basic Science Faculty Publications

The extent to which the benefits of bariatric surgery may be maintained by lifestyle changes after surgery is unclear. Our hypothesis is that exercise may sustain some metabolic benefits and counteract some of the adverse effects of surgery. In this review, we present findings supporting the proposition that exercise is key to improving overall health in patients after bariatric surgery.

Effects Of Water Stress And Auxin Application On Growth And Yield Of Two Sugarcane Cultivars Under Greenhouse Conditions, Jiraporn Bamrungrai, Brenda Tubana, Vidhaya Tre-Loges, Arunee Promkhambut, Anan Polthanee

Faculty Publications

Water stress (drought and flood) is one of the major factors that limits sugarcane growth and yield. The two greenhouse experiments were conducted at Khon Kaen University, Thailand. The first experiment investigated the individual and combined effects of droughts and floods on two sugarcane cultivars. The results showed that photosynthetic potential, based on chlorophyll a fluorescence (PSII) and chlorophyll content, exhibited a response to the water regime treatments. However, stomatal conductance in the K93-219 cultivar was higher than the KK3 cultivar. Similarly, plant height, number of tillers, number of stems, fresh stem weight, and sugar quality were not affected by …

Thirteen states associated with the Southern Extension and Research Activities Information Exchange Group-6 (SERA-IEG-6) agreed to share their soil test based P and K rate recommendations for nine major crops. The objectives were to compare fertilizer P and K rate recommendations, to look for opportunities to rationalize similar recommendations across state lines, and to examine challenges to the development of a cooperative regional approach to P and K recommendations. Mehlich-3 (eight states), Mehlich-1 (five states), or Lancaster (one state) extractions were the basis of plant available soil P (STP) and K (STK) assessment. Fertilizer recommendation philosophies (sufficiency, build and maintain, …

Functional And Phenotypic Evaluation Of Murine Cytomegalovirus Infection Of The Heart, Cassandra Marie Bonavita

LSU Doctoral Dissertations

Human Cytomegalovirus (HCMV) is a ubiquitous pathogen which infects 50-90% of the world population and results in lifelong latent infection with periodic transient reactivations. In immunocompetent populations acute infection is generally asymptomatic but seropositivity is associated with many chronic diseases, including cardiovascular disease. Despite 139 years of research into HCMV pathogenesis there is still no licensed vaccine and many gaps in the general knowledge of the virus. This includes the role of long term infection as it pertains to chronic diseases. In these studies, murine cytomegalovirus (MCMV) was used as a model of HCMV pathogenesis in the heart. MCMV shares …

Barbadin Potentiates Long-Term Effects Of Lorcaserin On Pomc Neurons And Weight Loss, Yang He, Hailan Liu, Na Yin, Yongjie Yang, Chunmei Wang, Meng Yu, Hesong Liu, Chen Liang, Julia Wang, Longlong Tu, Nan Zhang, Lina Wang, Yanlin He, Makoto Fukuda, Qi Wu, Zheng Sun, Qingchun Tong, Yong Xu

Division of Basic Science Faculty Publications

Obesity is a serious global health problem because of its increasing prevalence and comorbidities, but its treatments are limited. The serotonin 2C receptor (5-HT2CR), a G-protein-coupled receptor, activates proopiomelanocortin (POMC) neurons in the arcuate nucleus of hypothalamus (ARH) to reduce appetite and weight gain. However, several 5-HT analogs targeting this receptor, e.g., lorcaserin (Lor), suffer from diminished efficacy to reduce weight after prolonged administration. Here, we show that barbadin (Bar), a novel b-arrestin/b2-adaptin inhibitor, can prevent 5-HT2CR internalization in cells and potentiate long-term effects of Lor to reduce appetite and body weight in male mice. Mechanistically, we demonstrate that Bar …

Non-Destructive Trace Element Analysis Of Burials From Moho Cay, Belize, April Alyce Walton

LSU Master's Theses

The study of skeletal material macroscopically and microscopically can yield a plethora of information about interments’ lives. Studying bones at an elemental level can provide further details regarding dietary habits, residency, and migration patterns, which are important areas of research for Maya archaeology. Currently, research on bone composition is conducted through destructive methods, especially for archaeological bone. The use of non-destructive methods for testing bone composition such as with a portable x-ray fluorescence machine can also be suitable for the study of archaeological bone. This study has two main goals: to understand the interments' lives through strontium trace element and …

The Young Age And Plant-Based Diet Hypothesis For Low Sars-Cov-2 Infection And Covid-19 Pandemic In Sub-Saharan Africa, J N. Losso, M N. Losso, M Toc, J N. Inungu, J N. Losso

Faculty Publications

Since the outbreak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that caused the coronavirus disease-19 (COVID-19), in December 2019, the infection has spread around the globe. Some of the risk factors include social distancing, mask wearing, hand washing with soap, obesity, diabetes, hypertension, asthma, cardiovascular disease, and dysbiosis. Evidence has shown the incidence of total infection and death rates to be lower in sub-Saharan Africa when compared with North Africa, Europe and North America and many other parts of the world. The higher the metabolic syndrome rate, the higher the risk of SARS-CoV-2 infection. Africa has a lower …

Sufficient feeding is essential for animals’ survival, which requires a cognitive capability to facilitate food seeking, but the neurobiological processes regulating food seeking are not fully understood. Here we show that stimulation of agouti-related peptide-expressing (AgRP) neurons triggers a long-term depression (LTD) of spontaneous excitatory post-synaptic current (sEPSC) in adjacent pro-opiomelanocortin (POMC) neurons and in most of their distant synaptic targets, including neurons in the paraventricular nucleus of the thalamus (PVT). The AgRP-induced sEPCS LTD can be enhanced by fasting but blunted by satiety signals, e.g. leptin and insulin. Mice subjected to food-seeking tasks develop similar neural plasticity in AgRP-innervated …

Hepatic Nfe2l2 Is Not An Essential Mediator Of The Metabolic Phenotype Produced By Dietary Methionine Restriction, Han Fang, Kirsten P. Stone, Sujoy Ghosh, Laura A. Forney, Landon C. Sims, Leighann Vincik, Thomas W. Gettys

Division of Basic Science Faculty Publications

The principal sensing of dietary methionine restriction (MR) occurs in the liver, where it activates multiple transcriptional programs that mediate various biological components of the response. Hepatic Fgf21 is a key target and essential endocrine mediator of the metabolic phenotype produced by dietary MR. The transcription factor, Nfe2l2, is also activated by MR and functions in tandem with hepatic Atf4 to transactivate multiple, antioxidative components of the integrated stress response. However, it is unclear whether the transcriptional responses linked to Nfe2l2 activation by dietary MR are essential to the biological efficacy of the diet. Using mice with liver-specific deletion of …

Maximal oxygen uptake (VO2max) is a direct measure of human cardiorespiratory fitness and is associated with health. However, the molecular determinants of interindividual differences in baseline (intrinsic) VO2max, and of increases of VO2max in response to exercise training (ΔVO2max), are largely unknown. Here, we measure ~5,000 plasma proteins using an affinity-based platform in over 650 sedentary adults before and after a 20-week endurance-exercise intervention and identify 147 proteins and 102 proteins whose plasma levels are associated with baseline VO2max and ΔVO2max, respectively. Addition of a protein biomarker score derived from these proteins to a score based on clinical traits improves …

Risks Of Macrosomia Associated With Catechol-O-Methyltransferase Genotypes And Genetic-Epigenetic Interactions Among Children With And Without Gestational Diabetes Exposure, Liliana Aguayo, Weiqin Li, Brian T. Joyce, Junhong Leng, Yinan Zheng, Stephanie Shiau, Huikun Liu, Leishen Wang, Ru Gao, Andrea Baccarelli, Gang Hu, Lifang Hou

Population and Public Health Science Faculty Publications

Background: Gestational diabetes mellitus (GDM) is a major macrosomia risk factor. Variations in the catechol-O-methyltransferase (COMT; rs4680) genotypes are associated with heightened susceptibility to environmental exposures and nutritional conditions. However, macrosomia risks associated with COMT genetics, epigenetics, and the interaction between genetic and epigenetics among children with and without exposure to GDM are unknown. Methods: Data from women/children pairs (n = 1087) who participated in the Tianjin Gestational Diabetes Birth Cohort were used to examine the odds of being born with macrosomia associated with COMT-genotypes, 55 CpG sites located on the COMT gene, and genetic and epigenetic interactions. Odds of …

Population and Public Health Science Faculty Publications

Objective: Anthropometric measures of obesity, including BMI and waist circumference (WC), do not quantify excess adiposity and metabolic abnormalities consistently across racial populations. This study tested the hypothesis that participant race modifies the association of anthropometric measures of obesity and cancer risk. Methods: This prospective cohort (The Pennington Center Longitudinal Study) included 18,296 adults, 6,405 (35.0%) male sex and 6,273 (34.3%) Black race. The primary exposures were BMI (weight in kilograms/height in meters squared) and WC (centimeters). The primary end point was the time from study enrollment to diagnosis of histologically confirmed invasive cancer. Results: During a median follow-up of …

This study examined whether the neighborhood built environment moderated gestational weight gain (GWG) in LIFE-Moms clinical trials. Participants were 790 pregnant women (13.9 weeks’ gestation) with overweight or obesity randomized within four clinical centers to standard care or lifestyle intervention to reduce GWG. Geographic information system (GIS) was used to map the neighborhood built environment. The intervention relative to standard care significantly reduced GWG (coefficient = 0.05; p = 0.005) and this effect remained significant (p < 0.03) after adjusting for built environment variables. An interaction was observed for presence of fast food restaurants (coefficient = −0.007; p = 0.003). Post hoc tests based on a median split showed that the intervention relative to standard care reduced GWG in participants living in neighborhoods with lower fast food density 0.08 [95% CI, 0.03,0.12] kg/week (p = 0.001) but not in those living in areas with higher fast food density (0.02 [−0.04, 0.08] kg/week; p = 0.55). Interaction effects suggested less intervention efficacy among women living in neighborhoods with more grocery/convenience stores (coefficient = −0.005; p = 0.0001), more walkability (coefficient −0.012; p = 0.007) and less crime (coefficient = 0.001; p = 0.007), but post-hoc tests were not significant. No intervention x environment interaction effects were observed for total number of eating establishments or tree canopy. Lifestyle interventions during pregnancy were effective across diverse physical environments. Living in environments with easy access to fast food restaurants may limit efficacy of prenatal lifestyle interventions, but future research is needed to replicate these findings.

Implementation Of Dietary Methionine Restriction Using Casein After Selective, Oxidative Deletion Of Methionine, Han Fang, Kirsten P. Stone, Laura A. Forney, Landon C. Sims, Gabriela C. Gutierrez, Sujoy Ghosh, Thomas W. Gettys

Division of Basic Science Faculty Publications

Dietary methionine restriction (MR) is normally implemented using diets formulated from elemental amino acids (AA) that reduce methionine content to ∼0.17%. However, translational implementation of MR with elemental AA-based diets is intractable due to poor palatability. To solve this problem and restrict methionine using intact proteins, casein was subjected to mild oxidation to selectively reduce methionine. Diets were then formulated using oxidized casein, adding back methionine to produce a final concentration of 0.17%. The biological efficacy of dietary MR using the oxidized casein (Ox Cas) diet was compared with the standard elemental MR diet in terms of the behavioral, metabolic, …

High Protein Rice Flour In The Development Of Gluten Free Pasta, Ana Isabel Serrano Marana

LSU Master's Theses

Cahokia Rice is a biofortified high protein (10-12%) variety of rice. This rice has been evaluated and studied to create gluten-free products like cakes, muffins, and bread. This study was aimed to develop and analyze a gluten-free pasta using this high protein rice. Different pasta made with high-protein-white-rice-flour (HPWRP), high-protein-brown-rice flour (HPBRP), commercial-white-rice flour (CWRP), commercial-brown-rice flour (CBRP), and wheat-pasta (WP) as control were prepared and dried.

The cooking quality of the pasta was evaluated by measuring pasting properties, cooking time, water absorption capacity and cooking loss. Physical properties such as color and texture (firmness, compression energy, and work of …

Evaluation Of Food Safety Practices At Louisiana Summer Feeding Sites And Food Safety Communication Via Social Media During Crises, Peyton E. Haynes

LSU Master's Theses

The United States Department of Agriculture’s Summer Food Service Program (SFSP) provided children under the age of 18 in low-income areas 145 million free meals in 2018 through summer feeding sites. Food safety issues arise for Louisiana feeding sites due to time-temperature controlled foods served, weather patterns in Louisiana, seasonal staff and short operation time, and lack of equipment. The purpose of this study was to assess food safety practices at Louisiana feeding sites through observational study with intention to compare food practices at institutional and noninstitutional sites. A rubric following USDA food safety guidelines based on categories: hot holding, …

Mosquito Distribution And Stoichiometric Analysis Between Open And Closed Canopies In New Orleans Cemeteries, Rachel Rogers

LSU Master's Theses

Cemetery vases represent an important container habitat for mosquito larvae. Some species, like, Aedes albopictus and Aedes aegypti, prefer container habitats, whereas others, like Culex quinquefasciatus, will opportunistically use containers. In New Orleans, these three medically important vector species (Ae. albopictus Ae. aegypti, and Cx. quinquefasciatus) co-occur, despite a demonstrated competitive advantage of Ae. albopictus to the other two. Here we test the hypothesis that canopy cover from trees could be a mediating factor in driving mosquito assemblages in New Orleans, by influencing food sources, and the microclimate experienced by mosquito larvae. Samples from seven …

A Hindbrain Dopaminergic Neural Circuit Prevents Weight Gain By Reinforcing Food Satiation, Yong Han, Guobin Xia, Yanlin He, Yang He, Monica Farias, Yong Xu, Qi Wu

Division of Basic Science Faculty Publications

The neural circuitry mechanism that underlies dopaminergic (DA) control of innate feeding behavior is largely uncharacterized. Here, we identified a subpopulation of DA neurons situated in the caudal ventral tegmental area (cVTA) directly innervating DRD1-expressing neurons within the lateral parabrachial nucleus (LPBN). This neural circuit potently suppresses food intake via enhanced satiation response. Notably, this cohort of DAcVTA neurons is activated immediately before the cessation of each feeding bout. Acute inhibition of these DA neurons before bout termination substantially suppresses satiety and prolongs the consummatory feeding. Activation of postsynaptic DRD1LPBN neurons inhibits feeding, whereas genetic deletion of Drd1 within the …
