Design Of Endothelial Progenitor Cellular Constructs For Therapeutic Angiogenesis Applications, Ximena Vial

Open Access Dissertations

The goal of therapeutic angiogenesis is the development of functional and mature vasculature by combining biological and physical cues that mimic the native extracellular matrix. In this study we evaluated if immobilizing vascular endothelial growth factor (VEGF) gradients and SDF-1α on gelatin nanofibrous scaffolds with different fiber orientations (i.e. random or aligned) influence the angiogenic potential of endothelial progenitor cells (EPCs) and human umbilical vein endothelial cells (HUVECs). Both cell types successfully adhered onto gelatin B scaffolds. VEGF gradients alone or combined with SDF-1α as well as fiber orientation had a pronounced effect on cell behavior, morphology and orientation. Cells …

Secretion Of Interferon Gamma From Human Immune Cells Is Altered By Exposure To Tributyltin And Dibutyltin, Shanieek Lawrence, Jacqueline Reid, Margaret Whalen

Chemistry Faculty Research

Tributyltin (TBT) and dibutyltin (DBT) are widespread environmental contaminants found in food, beverages, and human blood samples. Both of these butyltins (BTs) interfere with the ability of human natural killer (NK) cells to lyse target cells and alter secretion of the pro-inflammatory cytokine tumor necrosis factor alpha (TNFα) from human immune cells in vitro. The capacity of BTs to interfere with secretion of other pro-inflammatory cytokines has not been examined. Interferon gamma (IFNγ) is a modulator of adaptive and innate immune responses, playing an important role in overall immune competence. This study shows that both TBT and DBT alter secretion …

Using Expression Profiling To Understand The Effects Of Chronic Cadmium Exposure On Mcf-7 Breast Cancer Cells, Zelmina Lubovac-Pilav, Daniel M. Borras, Esmeralda Ponce, Maggie Louie

Collected Faculty Scholarship

Cadmium is a metalloestrogen known to activate the estrogen receptor and promote breast cancer cell growth. Previous studies have implicated cadmium in the development of more malignant tumors; however the molecular mechanisms behind this cadmium-induced malignancy remain elusive. Using clonal cell lines derived from exposing breast cancer cells to cadmium for over 6 months (MCF-7-Cd4, -Cd6, -Cd7, -Cd8 and -Cd12), this study aims to identify gene expression signatures associated with chronic cadmium exposure. Our results demonstrate that prolonged cadmium exposure does not merely result in the deregulation of genes but actually leads to a distinctive expression profile. The genes deregulated …

Purifying The Human Rna-Lariat Debranching Enzyme, Ammar Saigal

Honors Program Theses and Research Projects

This project is my first official research endeavor and it involved becoming acquainted with a large variety of biochemistry and molecular biology techniques. The goal is to elucidate the structure of a protein common to most if not all cells of organisms within the Domain Eukarya, which is one of the three taxonomic domains into which all life is categorized. This is the domain most relevant to human beings as it includes plants, fungi, and animals (from a strictly biologically-taxonomic perspective, the species Homo sapiens to which you and I belong is considered belonging to the Kingdom Animalia [Animal]).

Bradyrhizobium sp. strain WSM1417 is an aerobic, motile, Gram-negative, non-spore-forming rod that was isolated from an effective nitrogen (N2) fixing root nodule of Lupinus sp. collected in Papudo, Chile, in 1995. However, this microsymbiont is a poorly effective N2 fixer with the legume host Lupinus angustifolius L.; a lupin species of considerable economic importance in both Chile and Australia. The symbiosis formed with L. angustifolius produces less than half of the dry matter achieved by the symbioses with commercial inoculant strains such as Bradyrhizobium sp. strain WSM471. Therefore, WSM1417 is an important candidate strain with which to investigate the genetics …

Ecology, Phylogenetics, And Conservation Of Draba Asterophora Complex: A Rare, Alpine, Endemic From Lake Tahoe, Usa, Emily Ruth Smith Putnam

Theses and Dissertations

Rare, alpine, endemic species are particularly at risk for extinction. Alpine environments are especially vulnerable to climate change and human impacts, such as ski resort development and snowmaking. Draba asterophora Payson is a rare, alpine species that occurs only in three disjunct mountain-top regions surrounding Lake Tahoe. It is currently threatened by human impacts, such as ski resorts, as well as indirect influences of climate change and therefore in need of better understanding for conservation purposes. Draba asterophora may be able to serve as a case study for other similarly vulnerable, rare, alpine, endemic species with conservation needs. We utilized …

Water As A Trophic Currency In Dryland Food Webs, Daniel C. Allen, Kevin E. Mccluney, Stephen R. Elser, John L. Sabo

Biological Sciences Faculty Publications

Water is essential for life on Earth, yet little is known about how water acts as a trophic currency, a unit of value in determining species interactions in terrestrial food webs. We tested the relative importance of groundwater and surface water in riparian food webs by manipulating their availability in dryland floodplains. Primary consumers (crickets) increased in abundance in response to added surface water and groundwater (contained in moist leaves), and predators (spiders and lizards) increased in abundance in response to added surface water, in spite of the presence of a river, an abundant water source. Moreover, the relative magnitude …

Validity And Reliability Of Using A Self-Lavaging Device For Cytology And Hpv Testing For Cervical Cancer Screening: Findings From A Pilot Study, Heidi E. Jones, Mahesh M. Mansukhani, Guo-Xia Tong, Carolyn L. Westhoff

Publications and Research

Self-sampling could increase cervical cancer screening uptake. While methods have been identified for human papillomavirus (HPV) testing, to date, self-sampling has not provided adequate specimens for cytology. We piloted the validity and reliability of using a self-lavaging device for cervical cytology and HPV testing. We enrolled 198 women in New York City in 2008–2009 from three ambulatory clinics where they received cervical cancer screening. All were asked to use the Delphi Screener™ to self-lavage 1–3 months after clinician-collected index cytological smear (100 normal; 98 abnormal). Women with abnormal cytology results from either specimen underwent colposcopy; 10 women with normal results …

Effects Of Reproductive Condition, Roost Microclimate, And Weather Patterns On Summer Torpor Use By A Vespertilionid Bat, Joseph S. Johnson, Michael J. Lacki

Forestry and Natural Resources Faculty Publications

A growing number of mammal species are recognized as heterothermic, capable of maintaining a high-core body temperature or entering a state of metabolic suppression known as torpor. Small mammals can achieve large energetic savings when torpid, but they are also subject to ecological costs. Studying torpor use in an ecological and physiological context can help elucidate relative costs and benefits of torpor to different groups within a population. We measured skin temperatures of 46 adult Rafinesque's big-eared bats (Corynorhinus rafinesquii) to evaluate thermoregulatory strategies of a heterothermic small mammal during the reproductive season. We compared daily average and minimum skin …

Flexibility In Food Extraction Techniques In Urban Free-Ranging Bonnet Macaques, Macaca Radiata, Madhur Mangalam, Mewa Singh

Journal Articles

Non-human primate populations, other than responding appropriately to naturally occurring challenges, also need to cope with anthropogenic factors such as environmental pollution, resource depletion, and habitat destruction. Populations and individuals are likely to show considerable variations in food extraction abilities, with some populations and individuals more efficient than others at exploiting a set of resources. In this study, we examined among urban free-ranging bonnet macaques, Macaca radiata (a) local differences in food extraction abilities, (b) between-individual variation and within-individual consistency in problem-solving success and the underlying problem-solving characteristics, and (c) behavioral patterns associated with higher efficiency in food extraction. When …

Transcriptional Co-Repressor Response Of Arabidopsis Thaliana To Different Abiotic Stress, Bhuwan Guragain

LSU New Orleans Theses and Dissertations

Plants adapt to the complex environmental challenges by regulating their gene expression. Analyses of plant genomes have identified many genes that are either expressed or repressed during environmental stress. However we do not have much information on gene repression. Transcriptional repression in Arabidopsis thaliana is caused by co-repressors that lack the DNA binding domain and are recruited by transcription factors to regulate target gene expression. The Sridhar lab has identified co-repressors SLK1, SLK2, and LUH, which prevent the expression of stress response genes under non-stress conditions. Arabidopsis transgenic lines expressing the GUS under the control of co-repressor’s promoter were created, …

Anxiety Sensitivity And Its Association With Parenting Behaviors, Rebecca Graham

LSU New Orleans Theses and Dissertations

The aim of this study was to examine the association between parent and child anxiety sensitivity in the context of parenting behaviors, specifically by testing parenting behaviors as moderators or mediators of the association between parent and child anxiety sensitivity. Past research implies that parent anxiety sensitivity may be more related to child anxiety sensitivity (moderation) in girls and in the context of certain parenting. Alternatively, parenting behaviors may better account for the association (mediate) between parent and child anxiety sensitivity. To test the hypotheses 191 families (n = 255 youth aged 6-17 and their parents) completed measures of …

Anion-Peptide Adduct Formation And Decomposition As Studied By Fourier Transform Ion Cyclotron Resonance (Ft-Icr) Mass Spectrometry, Xiaohua Liu

LSU New Orleans Theses and Dissertations

A new “best match” match model has been developed to account for adduct formation on multiply charged peptides observed in negative ion electrospray mass spectrometry. To obtain a stable adduct, the model necessitates an approximate matching of apparent gas-phase basicity (GBapp) of a given proton bearing site on the peptide with the gas-phase basicity (GB) of the anion attaching at that site. Evidence supporting the model is derived from the fact that singly charged adducts were only observed for lower GB anions: HSO₄^-, I^-, CF₃COO^-. Ions that have medium GBs (NO …
