The Effect Of Exogenous Leptin On Murine Dendritic Cell Morphology And Function, Christine Delgado Jan 2009

The Effect Of Exogenous Leptin On Murine Dendritic Cell Morphology And Function, Christine Delgado

Open Access Theses & Dissertations

Leptin is a pleiotropic hormone primarily secreted by white adipose tissue. Although originally found to regulate food intake and energy expenditure, it is now known to also significantly affect the immune system. In this study we assessed the effect of leptin on bone marrow derived dendritic cell (BM-DC) cytoskeletal structure and functionality. Our preliminary data demonstrates that the addition of physiological concentrations of exogenous leptin to BM-DC causes cytoskeletal rearrangement specifically that of actin as evidenced by increased number of llamelopodia/dendrites and increased staining for actin within the llamelopodia/dendrite region. This suggests that leptin is a necessary component of DC …


The Taxonomic Designation Of Eriogonum Corymbosum Var. Nilesii (Polygonaceae) Is Supported By Aflp And Cpdna Analyses, M. W. Ellis, J. M. Roper, R. Gainer, J. P. Der, Paul G. Wolf Jan 2009

Biology Faculty Publications

We examined populations of perennial, shrubby buckwheats in the Eriogonum corymbosum complex and related Eriogonum species in the subgenus Eucycla, to assess genetic affiliations of the recently named E. corymbosum var. nilesii. The known populations of this varietyare all located in Clark County, Nevada, U. S. A. We compared AFLP profiles and chloroplast DNA sequences of plants sampled from populations of E. corymbosum var. nilesii with those of plants representing other E. corymbosum varieties and related Eriogonum species from Colorado,Utah, northern Arizona, and northern New Mexico. We found evidence of genetic cohesion among the Clark County populations as well astheir …


Global Chloroplast Phylogeny And Biogeography Of Bracken (Pteridium: Dennstaedtiaceae), J. P. Der, J. A. Thomson, J. K. Stratford, Paul G. Wolf Jan 2009

Global Chloroplast Phylogeny And Biogeography Of Bracken (Pteridium: Dennstaedtiaceae), J. P. Der, J. A. Thomson, J. K. Stratford, Paul G. Wolf

Biology Faculty Publications

Bracken ferns (genus Pteridium) represent an ancient species complex with a natural worldwide distribution. Pteridium has historically been treated as comprising a single species, but recent treatments have recognized several related species. Phenotypic plasticity, geographically structured morphological variation, and geographically biased sampling have all contributed to taxonomic confusion in the genus. We sampled bracken specimens worldwide and used variable regions of the chloroplast genome to investigate phylogeography and reticulate evolution within the genus. Our results distinguish two major clades within Pteridium, a primarily northern hemisphere Laurasian/African clade, which includes all taxa currently assigned to P. aquilinum, and a primarily southern …


Conservation Of Selection On Matk Following An Ancient Loss Of Its Flanking Intron, A. M. Duffy, S. A. Kelchner, Paul G. Wolf Jan 2009

Conservation Of Selection On Matk Following An Ancient Loss Of Its Flanking Intron, A. M. Duffy, S. A. Kelchner, Paul G. Wolf

Biology Faculty Publications

The chloroplast gene trnK and its associated group II intron appear to be absent in a large and ancient clade that includes nearly 90% of fern species. However, the maturase protein encoded within the intron (matK) is still present and located on the boundary of a large-scale inversion. We surveyed the chloroplast genome sequence of clade-member Adiantum capillus-veneris for evidence of a still present but fragmented trnK intron. Lack of signature structural domains and sequence motifs in the genome indicate loss of the trnK intron through degradation in an ancestor of the clade. In plants, matK preferentially catalyzes splicing of …


Comparison Of The Compositional Proclivities Of The Complete Genomes Of Plasmodium Falciparum And Human, April Williams, Yuriy Fofanov, Catherine Putonti Jan 2009

Comparison Of The Compositional Proclivities Of The Complete Genomes Of Plasmodium Falciparum And Human, April Williams, Yuriy Fofanov, Catherine Putonti

Bioinformatics Faculty Publications

Pathogens and hosts have a dynamic relationship, one that is ever changing at the molecular level - the pathogen influencing the evolutionary path of the host and the host influencing the evolutionary path of the pathogen. The pathogen’s adaptation to a particular host could serve several purposes, e.g. to mimic the host to avoid detection, to take advantage of the host’s cellular machinery, to increase virulence, etc. Recognizing these adaptations is far from trivial, particularly when the size of the pathogen’s and host’s genomes differ by orders of magnitudes. Novel algorithms and data structures have been developed in our laboratory …

The 5' Bop Gene Stem-Loop Sequence: Stability, Structure, And Function, Srikanth Tangelloju Jan 2009

The 5' Bop Gene Stem-Loop Sequence: Stability, Structure, And Function, Srikanth Tangelloju

Seton Hall University Dissertations and Theses (ETDs)

In pursuit of GPCR characterization, our lab chose to work with a model organism Halobacterium salinarum (H sal). This organism contains the bacterioopsin gene (bop), which encodes the protein precursor of the purple membrane protein bacterioopsin (Bop). The bacterioopsin gene (bop) was chosen as the reporter for the study. The putative stem-loop structure within the bop gene is considered to be a key component of the molecular machinery that regulates Bop synthesis. Previous work in our lab has indicated that single base pair disruptions dramatically reduced stem-loop stability (differential scanning calorimetry (DSC), circular dichroism (CD) and ultraviolet (UV) spectroscopy analysis). …


Dispersion Of Large-Seeded Tree Species By Two Forest Primates: Primate Seed Handling, Microhabitat Variability, And Post-Dispersal Seed Fate, Nicole D. Gross-Camp Jan 2009

Dispersion Of Large-Seeded Tree Species By Two Forest Primates: Primate Seed Handling, Microhabitat Variability, And Post-Dispersal Seed Fate, Nicole D. Gross-Camp

Antioch University Dissertations & Theses

I describe the relative effectiveness of two primates in dispersing large-seeded tree seeds (> 0.5 cm) in the Nyungwe National Park (NNP), Rwanda. My objectives are three-fold: (1) to describe the relative effectiveness of primates in dispersing the seeds of five large-seeded tree species, (2) to evaluate the influence of primate seed-handling method on seed fate, and (3) to determine the influence of deposition site on seed fate. I employed focal tree observations, day-follows of habituated primate groups, in situ monitoring of primate-dispersed seeds, and experimental plots to achieve these objectives. Data were collected over the course of one year …


Potential Export Of Unattached Benthic Macroalgae To The Deep Sea Through Wind Driven Langmuir Circulation, H. M. Dierssen, Richard C. Zimmerman, Lisa A. Drake, David J. Burdige Jan 2009

Potential Export Of Unattached Benthic Macroalgae To The Deep Sea Through Wind Driven Langmuir Circulation, H. M. Dierssen, Richard C. Zimmerman, Lisa A. Drake, David J. Burdige

OES Faculty Publications

Carbon export to the deep sea is conventionally attributed to the sinking of open ocean phytoplankton. Here, we report a Langmuir supercell event driven by high winds across the shallow Great Bahama Bank that organized benthic non-attached macroalgae, Colpomenia sp., into visible windrows on the seafloor. Ocean color satellite imagery obtained before and after the windrows revealed a 588 km2 patch that rapidly shifted from highly productive macroalgae to bare sand. We assess a number of possible fates for this macroalgae and contend that this event potentially transported negatively buoyant macroalgae to the deep Tongue of the Ocean …

OES Faculty Publications

Iron availability and temperature are important limiting factors for the biota in many areas of the world ocean, and both have been predicted to change in future climate scenarios. However, the impacts of combined changes in these two key factors on microbial trophic dynamics and nutrient cycling are unknown. We examined the relative effects of iron addition (+1 nM) and increased temperature (+4° C) on plankton assemblages of the Ross Sea, Antarctica, a region characterized by annual algal blooms and an active microbial community. Increased iron and temperature individually had consistently significant but relatively minor positive effects on total phytoplankton …


Warming Of The Antarctic Ice-Sheet Surface Since The 1957 International Geophysical Year, Eric J. Steig, David P. Schneider, Scott Rutherford, Michael E. E. Mann, Josefino C. Comiso, Drew T. Shindell Jan 2009

Warming Of The Antarctic Ice-Sheet Surface Since The 1957 International Geophysical Year, Eric J. Steig, David P. Schneider, Scott Rutherford, Michael E. E. Mann, Josefino C. Comiso, Drew T. Shindell

Arts & Sciences Faculty Publications

Assessments of Antarctic temperature change have emphasized the contrast between strong warming of the Antarctic Peninsula and slight cooling of the Antarctic continental interior in recent decades. This pattern of temperature change has been attributed to the increased strength of the circumpolar westerlies, largely in response to changes in stratospheric ozone. This picture, however, is substantially incomplete owing to the sparseness and short duration of the observations. Here we show that significant warming extends well beyond the Antarctic Peninsula to cover most of West Antarctica, an area of warming much larger than previously reported. West Antarctic warming exceeds 0.1 °C …


Acceptance Of Evolution Increases With Student Academic Level: A Comparison Between A Secular And A Religious College, Guillermo Paz-Y-Mino C., Avelina Espinosa Jan 2009

Acceptance Of Evolution Increases With Student Academic Level: A Comparison Between A Secular And A Religious College, Guillermo Paz-Y-Mino C., Avelina Espinosa

Arts & Sciences Faculty Publications

Acceptance of evolution among the general public, high schools, teachers, and scientists has been documented in the USA; little is known about college students’ views on evolution; this population is relevant since it transits from a high-school/parent-protective environment to an independent role in societal decisions. Here we compare perspectives about evolution, creationism, and intelligent design (ID) between a secular (S) and a religious (R) college in the Northeastern USA. Interinstitutional comparisons showed that 64% (mean S + R) biology majors vs. 42/62% (S/R) nonmajors supported the exclusive teaching of evolution in science classes; 24/29% (S/R) biology majors vs. 26/38% (S/R) …

The Numerical Comparison Of Flow Patterns And Propulsive Performances For The Hydromedusae Sarsia Tubulosa And Aequorea Victoria, Mehmet Sahin, Kamran Mohseni, Sean Colin Jan 2009

The Numerical Comparison Of Flow Patterns And Propulsive Performances For The Hydromedusae Sarsia Tubulosa And Aequorea Victoria, Mehmet Sahin, Kamran Mohseni, Sean Colin

Arts & Sciences Faculty Publications

The thrust-generating mechanism of a prolate hydromedusa Sarsia tubulosa and an oblate hydromedusa Aequorea victoria was investigated by solving the incompressible Navier–Stokes equations in the swirl-free cylindrical coordinates. The calculations clearly show the vortex dynamics related to the thrust-generating mechanism, which is very important for understanding the underlying propulsion mechanism. The calculations for the prolate jetting hydromedusa S. tubulosa indicate the formation of a single starting vortex ring for each pulse cycle with a relatively high vortex formation number. However, the calculations for the oblate jet-paddling hydromedusa A. victoria indicate shedding of the opposite-signed vortex rings very close to each …


Crawling To Collapse: Ecologically Unsound Ornamental Invertebrate Fisheries, Andrew L. Rhyne, Randi Rotjan, Andrew Bruckner, Michael Tlusty Jan 2009

Crawling To Collapse: Ecologically Unsound Ornamental Invertebrate Fisheries, Andrew L. Rhyne, Randi Rotjan, Andrew Bruckner, Michael Tlusty

Arts & Sciences Faculty Publications

Background: Fishery management has historically been an inexact and reactionary discipline, often taking action only after a critical stock suffers overfishing or collapse. The invertebrate ornamental fishery in the State of Florida, with increasing catches over a more diverse array of species, is poised for collapse. Current management is static and the lack of an adaptive strategy will not allow for adequate responses associated with managing this multi-species fishery. The last decade has seen aquarium hobbyists shift their display preference from fish-only tanks to miniature reef ecosystems that include many invertebrate species, creating increased demand without proper oversight. The once …


Transcriptional Regulation Of Soluble Guanylyl Cyclase, Ashling Hampson Jan 2009

Transcriptional Regulation Of Soluble Guanylyl Cyclase, Ashling Hampson

Masters

Each year cardiovascular disease causes over 4.3 million deaths in Europe and is the cause of nearly one in three deaths in the US. Nitric oxide (NO) is a toxic atmospheric gas which exists in tissues as a biological product of mammalian cells. It has been used to manage cardiovascular disease for over a century and to this day remains an important treatment option in cardiovascular medicine. NO is produced by many cells in the body including vascular endothelial cells. Because of its importance in vascular function, abnormal production of NO, which occurs in different disease states, can adversely affect …


Tidal Influences On Bacterial And Phytoplankton Abundances And The Resulting Effects On Patterns Of Dissolved Oxygen In The Skidaway River Estuary, Casey Colleen Brazell Jan 2009

Tidal Influences On Bacterial And Phytoplankton Abundances And The Resulting Effects On Patterns Of Dissolved Oxygen In The Skidaway River Estuary, Casey Colleen Brazell

College of Graduate Studies: Theses & Dissertations

Two studies were conducted to investigate the physical and biological processes contributing to the dissolved oxygen (DO) availability in the Skidaway River Estuary (SRE), Savannah, GA during the summer of 2005. A temporal study looked at changes in DO concentrations, Chlorophyll a concentrations, bacterial abundance, water depth, and salinity, every hour, for 26 hours, over both a neap and a spring tide. A spatial study looked at changes in the above variables at 5 sites along the SRE while following the tide inland during a neap high and low tide, and a spring high and low tide. DO concentrations varied …


Effects Of Habitat Quality On Reproduction In Two Georgia Populations Of Gopherus Polyphemus, Jaqueline W. Entz Jan 2009

Effects Of Habitat Quality On Reproduction In Two Georgia Populations Of Gopherus Polyphemus, Jaqueline W. Entz

College of Graduate Studies: Theses & Dissertations

Author's Abstract: The purpose of this study was to examine differences in maternal investment by examining variation in the habitat structure and reproductive parameters for two populations of Gopherus polyphemus in Southeast GA. Both habitat structure and reproductive parameters for these populations are known from a previous study, thus this study expands upon the previous one and addresses four main questions. (1) Has habitat quality changed in the past ten years within and between population sites? (2) Could a change of habitat have affected female morphology or female reproductive parameters within or between populations? (3) Is female body size shaping …

Electricity Generation And Ethanol Production Using Iron-Reducing, Haloalkaliphilic Bacteria, Varun Paul

Masters Theses

"Microbial life in extreme environments has been studied primarily for their metabolic activities. Very few commercial or industrial applications have been known from these systems. In this study, the metabolic pathways and properties of bacteria from a haloalkaliphilic environment of Soap Lake, Washington were employed in two research applications related to energy production. In the first study, the bacterial cultures that were known to reduce iron (III) were used in a Microbial Fuel Cell (MFC) reactor. Iron reducing bacteria have shown to shunt their electrons on to the surface of a carbon electrode of an MFC, and the electrons can …


Physiological Genomics Of Spinal Cord And Limb Regeneration In A Salamander, The Mexican Axolotl, James Robert Monaghan Jan 2009

Physiological Genomics Of Spinal Cord And Limb Regeneration In A Salamander, The Mexican Axolotl, James Robert Monaghan

University of Kentucky Doctoral Dissertations

Salamanders have a remarkable ability to regenerate complex body parts including the limb, tail, and central nervous system. Although salamander regeneration has been studied for several hundred years, molecular-level studies have been limited to a relatively few important transcription factors and signaling molecules that are highly conserved among animals. Physiological genomic approaches were used here to investigate spinal cord and limb regeneration. Chapter 2 reports that hundreds of gene expression changes were identified during spinal cord regeneration, showing that a diverse injury response is activated in concert with extracellular matrix remodeling mechanisms during the early acute phase of natural spinal …


Transcriptional And Morphological Changes During Thyroxine-Induced Metamorphosis Of The Mexican Axolotl And Axolotl-Tiger Salamander Hybrids, Robert Bryce Page Jan 2009

Transcriptional And Morphological Changes During Thyroxine-Induced Metamorphosis Of The Mexican Axolotl And Axolotl-Tiger Salamander Hybrids, Robert Bryce Page

University of Kentucky Doctoral Dissertations

For nearly a century, amphibian metamorphosis has served as an important model of how thyroid hormones regulate vertebrate development. Consequently metamorphosis has been studied in a number of ways including: morphologically, developmentally, ecologically, and from an endocrine perspective. Over the last two decades, much has been learned about the molecular basis of anuran (frog) metamorphosis. However, very little is known about the molecular underpinnings of urodele (salamander) metamorphosis. Using the axolotl and axolotl hybrids as models, I present some of the first studies on the gene expression changes that occur during urodele metamorphosis. In Chapter 1, the motivation for the …

Turkish Journal of Biology

Free radicals and other active derivatives of oxygen inactivate enzymes and important plant cellular components. Superoxide dismutases (SODs) have been identified as essential components in an organism´s defence mechanism. This study was devoted to the investigation of SOD activity in 13 durum wheat landraces from Iran and Azerbaijan under 2 (drought and normal) conditions. The effect of drought stress on SOD, chlorophyll content index (CCI), and chlorophyll degradation were studied. Significant differences between genotypes and the genotype × environment interaction among SOD and CCI content were identified. The mean comparison showed that the contents of SOD and CCI decreased in …


The Effects Of Oral Administration Of An Aqueous Extract Of Ficus Bengalensis Stem Bark On Some Hematological And Biochemical Parameters In Rats With Streptozotocin-Induced Diabetes, Mahalingam Gayathri, Krishnan Kannabiran Jan 2009

The Effects Of Oral Administration Of An Aqueous Extract Of Ficus Bengalensis Stem Bark On Some Hematological And Biochemical Parameters In Rats With Streptozotocin-Induced Diabetes, Mahalingam Gayathri, Krishnan Kannabiran

Turkish Journal of Biology

The effects of sub-chronic administration of an aqueous extract of Ficus bengalensis stem bark on hematological and biochemical parameters in rats with streptozotocin (STZ)-induced diabetes were evaluated. The possible protective effect of the F. bengalensis (500 mg/kg of body weight per day) extract on STZ-induced changes was evaluated over 12 weeks. The parameters evaluated were plasma proteins, including total protein albumin and globulin, non-protein nitrogenous substances, including urea, uric acid, and creatinine, and hematological indices, including total hemoglobin content, erythrocytes, leucocytes, and platelets counts. The aqueous extract had a significant (P < 0.05) protective effect against STZ-induced changes in terms of the markers of protein metabolism and hematological indices. Furthermore, increases in levels of non-protein nitrogenous substances were normalized in response to the administration of the extract. Thus, the aqueous extract of F. bengalensis had a significant protective effect on STZ-induced changes to biochemical and hematological parameters in the diabetic rats.


Hormonal Factors Of Anti-Mutagenesis Regulation, Mekhtizadeh Emin Rza Jan 2009

Hormonal Factors Of Anti-Mutagenesis Regulation, Mekhtizadeh Emin Rza

Turkish Journal of Biology

The genetic activity of phytohormones (Phs) was studied. The investigation was conducted with 4 plants (Allium fistulosum, Lycopersicon esculentum, Triticum aestivum, and Gossypium hirsutum). The action of Phs on plant genetic processes was evaluated by chromosome aberration testing. It was observed that the exogenic Phs exerted a stabilizing effect on spontaneous plant mutagenesis. The use of Phs before and after the action of mutagenic factors contributed to an increase in the anti-mutational or reparative function of the plants´ genes. It was observed that the Phs exhibited genoprotective or reparative activity. The absence of clearly expressed dependence of these effects on …

C-Banded Karyotype And Nucleolar Organizer Regions (Nors) Of Wild Boar, Sus Scrofa (Artiodactyla: Suidae) From Anatolia, Ati̇lla Arslan, İrfan Albayrak

Turkish Journal of Biology

The present study reports the karyotype, C-banding, and nucleolar organizer regions (NORs) of 6 Sus scrofa (Linnaeus, 1758) males from Anatolia. The karyotype of S. scrofa comprised (2n) 38 chromosomes, the number of chromosomal arms (FN) was 64, and the number of autosomal arms (FNa) was 60. C-positive regions appeared to be restricted to the centromeric regions of autosomes 1, and 13-18, and the entire long arm of the Y chromosome. Some autosomes had very slight C-bands. The X chromosome appeared to be entirely euchromatic. NORs were identified by the silver-staining technique and were observed on secondary constriction sites of …
