Maternal Hyperleptinemia Alters Placental Transcriptome And Progesterone Regulation Without Affecting Early Equine Fetal Growth, Lucinda L. Thorburn

LSU Master's Theses

While consequences of equine obesity are well defined, the extent to which persistent hyperleptinemia and accompanying leptin (Lep) resistance affect the fetal-maternal environment warrants further exploration. This study compared endocrine, fetal, placental, and uterine parameters during early pregnancy (through day 70) in mares with elevated leptin versus normal leptin (NL) concentrations. Fourteen mares were classified as either NL (n = 6; Lep 0.9 ± 0.3 ng/mL), moderate leptin (ML; n = 4; Lep 3.0 ± 0.3 ng/mL), or high leptin (HL; n = 4; Lep 5.8 ± 0.7 ng/mL) based on annual plasma leptin. Mares were artificially inseminated and induced …

Dose Characterization Of Galactic Cosmic Rays In The Human Brain: A Phits-Based Study With A Segmented Anatomical Phantom, Shanice N. Manning

LSU Master's Theses

Astronauts aboard the International Space Station (ISS) are chronically exposed to a complex space radiation environment composed of galactic cosmic rays (GCR), solar particles, and Earth's trapped radiation. These high-energy particles interact with spacecraft shielding, producing secondary particles that can penetrate inside and deposit energy in sensitive tissues. Although animal studies have been useful in assessing space radiation risks, anatomical and physiological differences limit their applicability to human anatomy especially neuroanatomy. To address this gap, we developed a computational framework to model radiation dose distribution within the human brain using Monte Carlo simulations in Particle and Heavy Ion Transport code …

Identification Of Functional Non-Coding Variants Associated With Orofacial Cleft, Priyanka Kumari, Ryan Z Friedman, Michael A White, Barak A Cohen, Et Al.

2020-Current year OA Pubs

Oral facial cleft (OFC) comprises cleft lip with or without cleft palate (CL/P) or cleft palate only. Genome wide association studies (GWAS) of isolated OFC have identified common single nucleotide polymorphisms (SNPs) in many genomic loci where the presumed effector gene (for example, IRF6 in the 1q32 locus) is expressed in embryonic oral epithelium. To identify candidates for functional SNPs at eight such loci we conduct a massively parallel reporter assay in a fetal oral epithelial cell line, revealing SNPs with allele-specific effects on enhancer activity. We filter these SNPs against chromatin-mark evidence of enhancers and test a subset in …

Role And Electrophysiological Properties Of Sexually Dimorphic Oxytocin Receptor Expressing Neurons In The Anteroventral Periventricular Nucleus Of The Female Mice, Armita Abdollahi Govar

LSU Doctoral Dissertations

Oxytocin is a neurohypophyseal hormone that plays a crucial role in regulating mother-infant bonding and maternal behavior. Oxytocin modulates sex-specific parental behaviors by binding to the oxytocin receptor (OXTR)-expressing neurons in the brain. This study investigates the sexually dimorphic OXTR neurons in the anteroventral periventricular nucleus (AVPV) to understand how oxytocin modulates behavior in females. Specifically, we explored the behavioral roles, neural projections, and intrinsic electrophysiological characteristics of these neurons in the female mice. Using immunohistochemistry revealed that the number of OXTR-expressing neurons was enhanced in postpartum females compared with virgin females, suggesting that these neurons are involved in female-specific …

Broken Rituals: Contending Gods And Sacred Cows In Religious Racial Reconciliation And Race Relations, Ewart E. Forde

LSU Doctoral Dissertations

Race remains one of the most important determinants of a host of sociological outcomes despite claims that social characteristics such as class matter more. For example, racial inequalities are apparent in educational outcomes and regarding to asset-ownership. Perhaps the most troubling evidence of persistent racial inequities is the killing of Black people by law enforcement officials or civilians while they are engaged in such mundane activities, such as jogging in a neighborhood or selling compact discs (CDs). In the aftermath of these unnatural killings, there are often calls for racial reconciliation, faith based racial reconciliation. In times where it appears …

Fast fashion companies, through modern technology, are able to reproduce stolen designs with haste. Currently, there are a few notable cases that have spawned from design theft, but their verdicts may be limited in their ability to change policy or raise significant legal issues. This article analyzes both current federal enforcement mechanisms and design practices …

Nitric Oxide Does Not Improve Liver Mitochondrial Function 48 Hours After Cecal Ligation And Perforation In Experimental Sepsis, Pierre Eyenga, Shey-Shing Sheu

Center for Translational Medicine Faculty Papers

Nitric oxide (NO) has a dual effect on mitochondria. Incubating liver mitochondria with NO improves oxidative phosphorylation (OXPHOS) efficiency by decreasing state 4 respiration more than ATP synthesis and preventing mitochondrial permeability transition pore (mPTP) opening. We evaluated the effect of L-arginine (L-arg), an NO donor, on isolated liver mitochondrial respiration and mPTP in sepsis. Male mice were subjected to cecal ligation and perforation (CLP) with saline resuscitation or sham. After 8, 24, and 48 h, with and without L-arg, we measured isolated liver mitochondrial respiration and cytochrome c oxidase (COX) activity using polarographic methods and calcium retention capacity (CRC) …

Altered Patterning Of Neural Activity In A Neuropathology, Clarissa Hoffman, Jingheng Cheng, Rodrigo Morales, Daoyun Ji, Yuri Dabaghian

Faculty, Staff and Students Publications

The dynamics of neural circuits and their role in mediating cellular and organismal phenomena remain poorly understood, despite numerous efforts to dissect these processes through precise instantaneous measurements or longer-time averages and approximations. We use an alternative approach: we investigate these dynamics at the system's mesoscale by analyzing spike trains and waveforms. These extended activity patterns carry robust, tractable information, are highly responsive to physiological specifics, and enable detailed tracking of circuit behavior. In particular, this methodology allows for characterizing the functionality of tau-pathology-afflicted hippocampal circuits and identifying circuit-level abnormalities that are missed by through traditional analyses. In healthy mice, …
