During the spring semester of 2021, researchers distributed a demographic questionnaire, the Health-Promoting Lifestyle Profile-II …


Feeding Performance And Survival Of Louisiana Poeciliid Fishes Exposed To Residential Wastewater Effluent, Jonathan Chapman Jan 2026

Feeding Performance And Survival Of Louisiana Poeciliid Fishes Exposed To Residential Wastewater Effluent, Jonathan Chapman

Masters Theses

Mosquitoes are a primary transmitter of vector-borne disease, and their larvae can thrive within shallow pools of stagnant water. Rainwater drainage ditches are a common sight in many communities, and in Louisiana, they are dually used as outlets for onsite residential wastewater discharge in neighborhoods disassociated from municipal sewage treatment. However, when discharge systems malfunction, the water becomes uninhabitable to mosquito predators, allowing mosquitoes to thrive. This research examines the predation performance of mosquitofish (Gambusia affinis), sailfin mollies (Poecilia latipinna), and least killifish (Heterandria formosa), the primary biological control agents utilized to combat mosquitoes within ditch communities. Individuals were captured …

Course outcomes were evaluated using …


Decoupling Of Reproduction And Lifespan Trade-Off In Caenorhabditis Elegans Through Microbial Programming, Nora M. Villafuerte Jan 2026

Decoupling Of Reproduction And Lifespan Trade-Off In Caenorhabditis Elegans Through Microbial Programming, Nora M. Villafuerte

LSU Master's Theses

The microbiome is increasingly recognized as a major regulator of host physiology. Using the Caenorhabditis elegans model, we investigated how natural commensal bacteria modulate host reproduction and lifespan through internal egg hatching, a phenotype in which retained embryos hatch within the maternal body. Screening strains from the CeMbio collection identified four focal strains Ochrobactrum BH3, Lelliottia JUb66, Pantoea BIGb0393, and Enterobacter CEent1 that significantly increased internal egg hatching during the late reproductive period. This contrasts with pathogenic bacteria, which induce early-onset internal egg hatching. Across the focal strains, worms exhibited reduced total brood size but an expanded reproductive window relative …

Alcohol And The Endocrine System: A Critical Review Of Disruptions, Potential Mechanisms, And Health Implications, Patricia E. Molina, Liz Simon Jan 2026

Alcohol And The Endocrine System: A Critical Review Of Disruptions, Potential Mechanisms, And Health Implications, Patricia E. Molina, Liz Simon

School of Graduate Studies Faculty Publications

The endocrine system coordinates and integrates cellular activity throughout the body by regulating cellular and organ function and maintaining homeostasis. Homeostasis, the dynamic maintenance of internal balance despite changing external or internal conditions, is essential for proper cellular function. The endocrine system achieves this through a complex regulatory network of hormone-mediated signaling among multiple endocrine organs, relying on precisely regulated synthesis and release of hormones and specific hormone-receptor interactions. Endocrine-mediated actions coordinate critical physiological processes, including growth, metabolism, reproduction, stress adaptation, and circadian rhythms throughout the lifespan. Endocrine glands—such as the hypothalamus, pituitary, thyroid, parathyroid glands, pancreas, adrenal glands, and …

An Examination Of Lysine Acetylation In The Context Of Bacterial Metabolism, Translation, And Regulation Of Gene Expression, Thomas Patrick Bank Jan 2026

An Examination Of Lysine Acetylation In The Context Of Bacterial Metabolism, Translation, And Regulation Of Gene Expression, Thomas Patrick Bank

Dissertations

Post-translational modifications are a critical tool bacteria employ to survive the challenges of microbial life. Acetylation continues to gain more recognition as a modification of unique importance because the sources of acetylation – acetyl-phosphate and acetyl-coenzyme-A – are critical metabolites associated with central carbon metabolism, acetate overflow metabolism and acetate assimilation. This suggests that acetylation, indelibly coupled to metabolic flux, integrates metabolic sensing with any cellular process or pathway where an acetylation alters the function of a protein. Intuitively, this makes sense. Of course, a bacterial cell would coordinate any cellular process closely with the amount of energy available to …

Circadian-Shaped Immune Variability Predicts Infection Outcome, Jonathan Lalsiamthara, Mariko Locke, Alejandro Aballay

Faculty, Staff and Student Publications

Disease risk and severity are influenced by genetics, epigenetics, and environmental factors. However, immune responses vary even among genetically similar or related individuals, shaped by inherited and noninherited factors. Using Caenorhabditis elegans, we found that pathogen susceptibility can be predicted by preinfection biomarkers. Individuals with high-basal expression of irg-5, an infection response gene regulated by the p38 mitogen-activated protein kinase-1 (PMK-1) pathway, were more susceptible to Pseudomonas aeruginosa infection. A genome-wide screen identified the myeloid ecotropic viral integration site-1 (MEIS) homeobox protein UNC-62 as a regulator of irg-5 expression, acting through PMK-1 and GATA binding erythroid-like transcription factor …

Breast and other solid tumors respond poorly to immune therapy. Myeloid cells (MCs) such as macrophages contribute to resistance. Established clinical evidence links cholesterol to cancer outcomes, with MC function being regulated by cholesterol metabolism. We screened MC-expressed regulators of cholesterol homeostasis linked to survival and identified the cholesterol efflux protein ABCA1. ABCA1 activity increases anticancer functions of macrophages: enhancing tumor infiltration, decreasing angiogenic potential, reducing efferocytosis, and improving support of CD8+ T cell activity. Mechanistically, different AKT isoforms are involved, through both PI3K-dependent and PI3K-independent mechanisms. Highlighting the clinical relevance of our findings are correlations between ABCA1 in macrophages …

Low Energy Availability (Lea) And Its Relationship To Nutritional Status And Bone Health In Collegiate Athletes, Anthony Dempsey Jan 2026

Low Energy Availability (Lea) And Its Relationship To Nutritional Status And Bone Health In Collegiate Athletes, Anthony Dempsey

UNH URC Open (2026 and after)

This project aims to identify low energy availability in a sample of collegiate athletes and explore the relationship with bone mineral density and nutrient deficiencies. Participants (n=3,407) were recruited from a northeast university and self-reported athlete status and physical activity via online questionnaire. Food records were used to calculate energy and nutrient intake. Anthropometrics including height, weight, body composition and bone mineral status were measured in duplicate. Energy availability (EA) was calculated as (Energy Intake (EI) -Exercising Energy Expenditure) (EEE)) /Fat Free Mass (FFM) (kg) and categorized as optimal (>45 kcal/kg FFM), subclinical, or clinically low (< 30 kcal/kg FFM). Fifteen percent of participants were characterized as athletes (club or division I varsity); mean EA was lower among athletes vs. nonathletes (17.90.7vs.21.90.3, p< .001). Males were more likely to have optimal EA status vs. females (8.8vs4.7%, p< .001). Most females (75.1%) were categorized as clinically LEA; 20.3% had subclinical LEA. Among men, athletes’ EA was similar to nonathletes (21.11.2vs22.20.5, p=.4); among females, athletes had lower EA vs. nonathletes (16.220.9vs21.70.3, p< .001). Males with clinically low EA were most likely to consume inadequate intakes of potassium, fiber, iron, and vitamin D (77.1,94.0,10.4 and 97.3%, respectively); similarly, females with clinically low EA, were most likely to consume inadequate intakes (81.9,87.6,88.3, and 99.5%, respectively). Bone z-scores were higher among athletes vs. non athletes (-.27±.06vs-.67±.02, p< .001) but were not different by EA status. Given the prevalence of LEA within the college athlete and nonathlete populations, further research and tailored nutritional education is needed for this at-risk population.
