Vitamin D Deficiency And Infertility: A Systematic Review, Susanne Stoddard Sollis

Student Works

Vitamin D regulates calcium and phosphorus homeostasis in the body. In recent years, studies have been conducted examining the role vitamin D plays in reproduction. Vitamin D deficiency is associated with infertility, decreased pregnancy rates, and hormonal changes. Asians appear to have a reverse correlation with pregnancy rates and vitamin D levels. There are some conflicting studies regarding vitamin D levels in relationship to infertility. This paper reviews the most recent literature focusing on the relationship between vitamin D status and infertility. This review evidences vitamin D levels >30 ng/mL result in improved fertility outcomes.

Compositional Differences In Simulated Root Exudates Elicit A Limited Functional And Compositional Response In Soil Microbial Communities, Michael S. Strickland, Rebecca L. Mcculley, Jim A. Nelson, Mark A. Bradford

Plant and Soil Sciences Faculty Publications

Inputs of low molecular weight carbon (LMW-C) to soil - primarily via root exudates- are expected to be a major driver of microbial activity and source of stable soil organic carbon. It is expected that variation in the type and composition of LMW-C entering soil will influence microbial community composition and function. If this is the case then short-term changes in LMW-C inputs may alter processes regulated by these communities. To determine if change in the composition of LMW-C inputs influences microbial community function and composition, we conducted a 90 day microcosm experiment whereby soils sourced from three different land …

Role Of Ime4 Protein In Pho Regulon Of S.Cerevisiae., Jenisha Ghimire

LSU New Orleans Theses and Dissertations

In the yeast Saccharomyces cerevisiae, the IME4 methyltransferase, interacts genetically with methyl binding protein, Pho92, to affect the expression of PHO regulon target genes. Cells mutant in IME4 or PHO92 show increases in the RNA abundance of PHO regulon target genes. The increase in the RNA abundance of the PHO regulon target genes is not additive in the cells double mutant in IME4 and PHO92. Hence, Ime4 and Pho92 interact in a single pathway in PHO regulon. Surprisingly, cells overexpressing IME4 and MUM2 shows increase in some PHO regulon target genes, indicating that IME4 affects the PHO regulon target …

Chasin’ Tail In Southern Alabama: Delineating Programmed And Stimulus-Driven Grooming In Odocoileus Virginianus, Kyle Heine

LSU New Orleans Theses and Dissertations

This study examined variation in ectoparasite density and grooming behavior of naturally occurring white-tailed deer (Odocoileus virginianus) in southwest Alabama. Stimulus-driven grooming as well as the intraspecific body size and vigilance principles of programmed grooming were tested. During the rut, males had a higher average tick (Ixodidae) density than females and exhibited complete separation of tick parasitism between non-rutting and rutting periods, supporting the vigilance principle. Stimulus-driven grooming was supported, as both fawns and yearlings had significantly higher fly (Hippoboscidae) and combined fly/tick densities than adults, and fawns oral groomed at a significantly higher rate than adults, even …

Stretch-Induced Increase In Cardiac Contractility Is Independent Of Myocyte Ca2+ While Block Of Stretch Channels By Streptomycin Improves Contractility After Is-Chemic Stunning, Samhita Rhodes, Amadou K. S. Camara, Mohammed Aldakkak, James S. Heisner, David F. Stowe

Open Access Publishing Support Funded Articles

Stretching the cardiac left ventricle (LV) enhances contractility but its effect on myoplasmic [Ca²⁺] is controversial. We measured LV pressure (LVP) and [Ca²⁺] as a function of intra-LV stretch in guinea pig intact hearts before and after 15 min global stunning ± perfusion with streptomycin (STM), a stretch-activated channel blocker. LV wall [Ca²⁺] was measured by indo-1 fluorescence and LVP by a saline-filled latex balloon inflated in 50 μL steps to stretch the LV. We implemented a mathematical model to interpret cross-bridge dynamics and myofilament Ca²⁺ responsiveness from the instantaneous relationship between [Ca …

The Predictive Utility Of Emotional Deficits And Callous-Unemotional Traits For Important Antisocial Outcomes In Juvenile Justice-Involved Youth, Laura C. Thornton

LSU New Orleans Theses and Dissertations

The current study investigated the predictive utility of callous-unemotional (CU) traits and emotional facilitation to distress (EFD) for multiple antisocial outcomes in a sample of juvenile justice-involved males. Although CU traits and EFD did not generally interact to predict antisocial outcomes, CU traits were a consistent predictor of total, proactive, and reactive forms of aggression over 18 months. Similarly, CU traits and time interacted to predict total and violent self-reported offending, such that CU traits were positively associated with both outcomes, but this association weakened over the 18 month timeframe. Racial and ethnic differences only emerged for the prediction of …

Parent And Child Vagal Tone: Examining Parenting Behaviors As Moderators Of The Association, Rebecca Graham

LSU New Orleans Theses and Dissertations

Research indicates that learning how to regulate one’s emotions is critical to successful child development and is associated with adaptive social functioning and psychological adjustment (Dunn & Brown, 1994; Eisenberg, Fabes, Guthrie, & Reiser, 2000; Eisenberg, Fabes, & Murphy, 1996). Children’s emotion regulation abilities are thought to be influenced by both child (e.g., age, temperament) and parent characteristics (e.g., parenting behaviors, parental regulation; Eisenberg, Cumberland, & Spinrad, 1998). Resting heart rate variability (HRV) has emerged as a potentially important biomarker associated with emotion regulation (Porges, 2007; Thayer & Lane, 2000); however, there are still significant gaps in research. In particular, …

Magnetic Nanoparticles Containing Labeling Reagents For Cell Surface Mapping, Ujwal S. Patil

LSU New Orleans Theses and Dissertations

Cell surface proteins play an important role in understanding cell-cell communication, cell signaling pathways, cell division and molecular pathogenesis in various diseases. Commonly used biotinylation regents for cell surface mapping have shown some potential drawbacks such as crossing the cell membrane, difficult recovery of biotinylated proteins from streptavidin/avidin beads, interference from endogenous biotin and nonspecific nature of streptavidin. With aim to solve these problems, we introduced sulfo-N-hydroxysuccinimidyl (NHS) ester functionalized magnetic nanoparticles containing cleavable groups to label solvent exposed primary amine groups of proteins. Silica coated iron oxide magnetic nanoparticles (Fe₃O₄@SiO₂ MNPs) were …

Food Insecurity Reported By Children, But Not By Mothers, Is Associated With Lower Quality Of Diet And Shifts In Foods Consumed, Jennifer Bernal, Edward A. Frongillo Jr., Juan A. Rivera

Faculty Publications

Household food security shows little indication of nutrient inadequacy among children, according to reports made by parents. We examined the associations of food insecurity as reported by children and mothers with children’s consumption of energy, macronutrients such as vitamin A, calcium, iron and zinc, and selected foods, and whether these associations differed by child’s gender. This cross-sectional study had non-probabilistic 128 Venezuelan mother–child pairs. We assessed food insecurity and management strategies in children using 10- and nine-item instruments, respectively. Mothers’ report of food insecurity came from a previously validated 12-item instrument. Nutrient intake of children was assessed with a 67-item …

Southern Ocean primary productivity plays a key role in global ocean biogeochemistry and climate. At the Southern Ocean sea ice edge in coastal McMurdo Sound, we observed simultaneous cobalamin and iron limitation of surface water phytoplankton communities in late Austral summer. Cobalamin is produced only by bacteria and archaea, suggesting phytoplankton–bacterial interactions must play a role in this limitation. To characterize these interactions and investigate the molecular basis of multiple nutrient limitation, we examined transitions in global gene expression over short time scales, induced by shifts in micronutrient availability. Diatoms, the dominant primary producers, exhibited transcriptional patterns indicative of co-occurring …

An Insight Into The Role Of Vitamins Other Than Vitamin D On Bone, Robert E. Salazar, Jameela Banu

Health & Biomedical Sciences Faculty Publications

Vitamins are essential micronutrients for normal development. Great emphasis has been placed on vitamin D for bone development and maintenance. However, other vitamins also influence bone health. While some of them are more beneficial to bone and increase bone mass by increasing bone formation, calcium deposition and stimulate osteoblastogenesis, higher concentrations of others have deleterious effects causing fragile bones and increasing the risk of fractures. Knowledge about the effects of these vitamins will help in better maintenance of bone. This review focuses on the information available on vitamins A,B,C,E and K on bone health. Existing information supports vitamin C and …

Photoluminescent Silicon Nanoparticles: Fluorescent Cellular Imaging Applications And Photoluminescence (Pl) Behavior Study, Sheng-Kuei Chiu

Dissertations and Theses

Molecular fluorophores and semiconductor quantum dots (QDs) have been used as cellular imaging agents for biomedical research, but each class has challenges associated with their use, including poor photostability or toxicity. Silicon is a semiconductor material that is inexpensive and relatively environmental benign in comparison to heavy metal-containing quantum dots. Thus, red-emitting silicon nanoparticles (Si NPs) are desirable to prepare for cellular imaging application to be used in place of more toxic QDs. However, Si NPs currently suffer poorly understood photoinstability, and furthermore, the origin of the PL remains under debate.

This dissertation first describes the use of diatomaceous earth …

Growth, Mortality, And Availability Of Eastern Pacific Sailfish, Mark Daniel Fitchett

Open Access Dissertations

The Indo-Pacific sailfish, Istiophorus platypterus, has significant ecological and socioeconomic importance in the tropical eastern Pacific Ocean (EPO). It is caught as bycatch in tuna commercial fisheries, but targeted in economically important catch-and-release recreational fisheries. The sustainability of this valuable resource had not been successfully assessed due to poor fishery landings and effort data with unreliable demographic estimates for sailfish. The goal of this dissertation was to assess lifetime demographics and stock mortality rates of sailfish and to infer ecosystem dynamics that drive availability of sailfish to recreational fisheries. This dissertation developed a new age and growth model for sailfish …

Resistance To Inhibitors Of Cholinesterase 3 (Ric-3) Expression Promotes Selective Protein Associations With The Human α7-Nicotinic Acetylcholine Receptor Interactome, Matthew J. Mulcahy, Sydney B. Blattman, Francisco J. Barrantes, Ronald J. Lukas, Edward Hawrot

Translational Neuroscience

The α7-nicotinic acetylcholine receptor (α7-nAChR) is a ligand-gated ion channel widely expressed in vertebrates and is associated with numerous physiological functions. As transmembrane ion channels, α7-nAChRs need to be expressed on the surface of the plasma membrane to function. The receptor has been reported to associate with proteins involved with receptor biogenesis, modulation of receptor properties, as well as intracellular signaling cascades and some of these associated proteins may affect surface expression of α7- nAChRs. The putative chaperone resistance to inhibitors of cholinesterase 3 (Ric-3) has been reported to interact with, and enhance the surface expression of, α7-nAChRs. In this …

Amylin Structure, Aggregation And Pancreatic Β Cell Toxicity, Sharadrao Patil

Doctoral Dissertations

In most type 2 diabetes patients, amyloid plaques have been found juxtaposed with membranes of pancreatic β-cells. These plaques are composed of amyloid fibrils of the 37 residue endocrine hormone amylin and cause distinct changes in cell membrane morphology associated with the destruction of β-cells. Research is still ongoing to identify the toxic species involved and the mechanisms by which mature fibrils or oligomers cause cytotoxicity. The projects undertaken were designed to study the molecular structural features of amylin, mechanism of amyloid aggregation and, to develop cytotoxicity inhibitors. We determined the structure of human amylin bound to SDS micelles using …

Taxonomy And Systematics Of The Herichthyins (Cichlidae: Tribe Heroini), With The Description Of Eight New Middle American Genera, Caleb D. Mcmahan, Wilfredo A. Matamoros, Kyle R. Piller, Prosanta Chakrabarty

Faculty Publications

In recent years great strides have been made for improving our understanding of the evolutionary relationships among neotropical cichlids, particularly within the clade Heroini and its crown clade the herichthyins. Most phylogenetic studies have largely converged on congruent topologies for relationships among species and major lineages within the herichthyins. One major aspect missing from previous studies of these cichlids is a formal taxonomic revision, including the redefining of genera. Based on analysis of 52 species and three mitochondrial and two nuclear loci, we generate a Bayesian phylogeny for the herichthyin cichlids, and formally revise the taxonomy for genera within this …

Application Of Β-Lactamase Reporter Fusions As An Indicator Of Effector Protein Secretion During Infections With The Obligate Intracellular Pathogen Chlamydia Trachomatis , Konrad E. Mueller, Kenneth A. Fields

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Chlamydia spp. utilize multiple secretion systems, including the type III secretion system (T3SS), to deploy host-interactive effector proteins into infected host cells. Elucidation of secreted proteins has traditionally required ectopic expression in a surrogate T3SS followed by immunolocalization of endogenous candidate effectors to confirm secretion by chlamydiae. The ability to transform Chlamydia and achieve stable expression of recombinant gene products has enabled a more direct assessment of secretion. We adapted TEM-1 β-lactamase as a reporter system for assessment of chlamydial protein secretion. We provide evidence that this system facilitates visualization of secretion in the context of infection. Specifically, our findings …
