The interphase nucleus exists as a highly dynamic system, the physical properties of which have functional importance in gene regulation. Not only can gene expression be influenced by the local sequence context, but also by the architecture of the nucleus in three-dimensions (3D), and by the interactions between these levels via chromatin modifications. A challenging task is to resolve the complex interplay between sequence- and genome structure-based control mechanisms. Here, we created a collection of 277 Arabidopsis lines that allow the visual tracking of individual loci in living plants while comparing gene expression potential at these locations, via an identical …

Morse Theory And Conjugacy Classes Of Finite Subgroups, Noel Brady, Matt Clay, Pallavi Dani Aug 2008

Morse Theory And Conjugacy Classes Of Finite Subgroups, Noel Brady, Matt Clay, Pallavi Dani

Faculty Publications

We construct a CAT(0) group containing a finitely presented subgroup with infinitely many conjugacy classes of finite-order elements. Unlike previous examples (which were based on right-angled Artin groups) our ambient CAT(0) group does not contain any rank 3 free abelian subgroups. We also construct examples of groups of type Fn inside mapping class groups, Aut(double-struck Fk), and Out(double-struck Fk) which have infinitely many conjugacy classes of finite-order elements. © 2008 Springer Science+Business Media B.V.

Okagbare, Juan Feng, Matuesz L. Hupert, Don Patterson, Jost Götten, Robin L. Mccarley, Dimitris Nikitopoulos, Michael C. Murphy, Steven A. Soper

Faculty Publications

A novel microfluidic device that can selectively and specifically isolate exceedingly small numbers of circulating tumor cells (CTCs) through a monoclonal antibody (mAB) mediated process by sampling large input volumes (≥1 mL) of whole blood directly in short time periods (<37 >min) was demonstrated. The CTCs were concentrated into small volumes (190 nL), and the number of cells captured was read without labeling using an integrated conductivity sensor following release from the capture surface. The microfluidic device contained a series (51) of high-aspect ratio microchannels (35 μm width x 150 μm depth) that were replicated in poly(methyl methacrylate), PMMA, from …

Temperature Sensitivity And Cell Division Defects In An Escherichia Coli Strain With Mutations In Yghb And Yqja, Encoding Related And Conserved Inner Membrane Proteins, Kandi Thompkins, Ballari Chattopadhyay, Ying Xiao, Margaret C. Henk, William T. Doerrler Jul 2008

Temperature Sensitivity And Cell Division Defects In An Escherichia Coli Strain With Mutations In Yghb And Yqja, Encoding Related And Conserved Inner Membrane Proteins, Kandi Thompkins, Ballari Chattopadhyay, Ying Xiao, Margaret C. Henk, William T. Doerrler

Faculty Publications

Ludox density gradients were used to enrich for Escherichia coli mutants with conditional growth defects and alterations in membrane composition. A temperature-sensitive mutant named Lud135 was isolated with mutations in two related, nonessential genes: yghB and yqjA. yghB harbors a single missense mutation (G203D) and yqjA contains a nonsense mutation (W92TGA) in Lud135. Both mutations are required for the temperature-sensitive phenotype: targeted deletion of both genes in a wild-type background results in a strain with a similar phenotype and expression of either gene from a plasmid restores growth at elevated temperatures. The mutant has altered membrane phospholipid levels, with elevated …

Preparation Of Botanical Samples For Biomedical Research, Zhijun Liu Jun 2008

Preparation Of Botanical Samples For Biomedical Research, Zhijun Liu

Faculty Publications

Plants are chemical storehouses, a fact which has driven countless multidisciplinary quests for bioactive compounds. As the very first step of botanical research, the whole desire is to find "hit" plants with specific bioactivities. It is logical to use some strategies that can maximize the chances of finding these "hits" with limited time and resources. In addition to selecting the right plants for screening, how the plant extracts are prepared can also influence the bioactivity screening outcomes. An extract from the same plant material can be quite different in chemical composition having different preparations. Because of the complex mixture nature …

Neuroprotection Via Matrix-Trophic Coupling Between Cerebral Endothelial Cells And Neurons, Shuzhen Guo, Woo Jean Kim, Josephine Lok, Sun Ryung Lee, Elaine Besancon, Bing Hao Luo, Monique F. Stins, Xiaoying Wang, Shoukat Dedhar, Eng H. Lo May 2008

Neuroprotection Via Matrix-Trophic Coupling Between Cerebral Endothelial Cells And Neurons, Shuzhen Guo, Woo Jean Kim, Josephine Lok, Sun Ryung Lee, Elaine Besancon, Bing Hao Luo, Monique F. Stins, Xiaoying Wang, Shoukat Dedhar, Eng H. Lo

Faculty Publications

The neurovascular unit is an emerging concept that emphasizes homeostatic interactions between endothelium and cerebral parenchyma. Here, we show that cerebral endothelium are not just inert tubes for delivering blood, but they also secrete trophic factors that can be directly neuroprotective. Conditioned media from cerebral endothelial cells broadly protects neurons against oxygen-glucose deprivation, oxidative damage, endoplasmic reticulum stress, hypoxia, and amyloid neurotoxicity. This phenomenon is largely mediated by endothelial-produced brain-derived neurotrophic factor (BDNF) because filtering endothelial-conditioned media with TrkB-Fc eliminates the neuroprotective effect. Endothelial production of BDNF is sustained by β-1 integrin and integrin-linked kinase (ILK) signaling. Noncytotoxic levels of …

Rapid Increases In Obesity In Jamaica, Compared To Nigeria And The United States, Ramón A. Durazo-Arvizu, Amy Luke, Richard S. Cooper, Guichan Cao, Lara Dugas, Adebowale Adeyemo, Michael Boyne, Terrence Forrester

Faculty Publications

Background. Weight gain in adulthood is now common in many populations, ranging from modest gains in developing countries to a substantial percentage of body weight in some Western societies. To examine the rate of change across the spectrum of low to high-income countries we compared rates of weight change in samples drawn from three countries, Nigeria, Jamaica and the United States. Methods. Population samples from Nigeria (n = 1,242), Jamaica (n = 1,409), and the US (n = 809) were selected during the period 1995-1999 in adults over the age of 19; participation rates in the original survey were 96%, …

Stand Structure And Dynamics Of Sand Pine Differ Between The Florida Panhandle And Peninsula, Paul B. Drewa, William J. Platt, Charles Kwit, Thomas W. Doyle May 2008

Stand Structure And Dynamics Of Sand Pine Differ Between The Florida Panhandle And Peninsula, Paul B. Drewa, William J. Platt, Charles Kwit, Thomas W. Doyle

Faculty Publications

Size and age structures of stand populations of numerous tree species exhibit uneven or reverse J-distributions that can persist after non-catastrophic disturbance, especially windstorms. Among disjunct populations of conspecific trees, alternative distributions are also possible and may be attributed to more localized variation in disturbance. Regional differences in structure and demography among disjunct populations of sand pine (Pinus clausa (Chapm. ex Engelm.) Vasey ex Sarg.) in the Florida panhandle and peninsula may result from variation in hurricane regimes associated with each of these populations. We measured size, age, and growth rates of trees from panhandle and peninsula populations and then …

Culture-Independent Identification Of Gut Bacteria In Fourth-Instar Red Imported Fire Ant, Solenopsis Invicta Buren, Larvae, Albert H. Lee, Claudia Husseneder, Linda Hooper-Bùi May 2008

Culture-Independent Identification Of Gut Bacteria In Fourth-Instar Red Imported Fire Ant, Solenopsis Invicta Buren, Larvae, Albert H. Lee, Claudia Husseneder, Linda Hooper-Bùi

Faculty Publications

Red imported fire ants (RIFA), Solenopsis invicta Buren, are medical, urban, and agricultural pests from South America. They are successful invaders due to their preference for disturbed habitats, high reproductive rates, and the ability to feed on a wide variety of food items (omnivorous). Fourth-instar larvae are used by the colony to digest solid food and then regurgitate it for consumption by workers and queens. Larvae are an ideal source of investigations of endosymbiotic bacteria possibly involved in nutrient distributions. Our study utilized 16S rDNA sequencing to describe the composition of the bacterial community in fourth-instar ant larvae in order …

Further Characterization Of Vibrio Vulnificus Rugose Variants And Identification Of A Capsular And Rugose Exopolysaccharide Gene Cluster, Brenda L. Grau, Margaret C. Henk, Katherine L. Garrison, Brett J. Olivier, Randall M. Schulz, Kathy L. O'Reilly, Gregg S. Pettis Apr 2008

Further Characterization Of Vibrio Vulnificus Rugose Variants And Identification Of A Capsular And Rugose Exopolysaccharide Gene Cluster, Brenda L. Grau, Margaret C. Henk, Katherine L. Garrison, Brett J. Olivier, Randall M. Schulz, Kathy L. O'Reilly, Gregg S. Pettis

Faculty Publications

Capsular polysaccharide (CPS) is a major virulence factor in Vibrio vulnificus, and encapsulated strains have an opaque, smooth (OpS) colony morphology, while nonencapsulated strains have a translucent, smooth (TrS) colony morphology. Previously, we showed that OpS and TrS parental strains can yield a third colony type, rugose (R), and that the resulting strains, with the OpR and TrR phenotypes, respectively, form copious biofilms. Here we show that while OpR and TrR strains both produce three-dimensional biofilm structures that are indicative of rugose extracellular polysaccharide (rEPS) production, OpR strains also retain expression of CPS and are virulent in an iron-supplemented mouse …

The Sinorhizobium Meliloti Msba2 Protein Is Essential For The Legume Symbiosis, Sebastian Beck, Victoria L. Marlow, Katy Woodall, William T. Doerrler, Euan K. James, Gail P. Ferguson Apr 2008

The Sinorhizobium Meliloti Msba2 Protein Is Essential For The Legume Symbiosis, Sebastian Beck, Victoria L. Marlow, Katy Woodall, William T. Doerrler, Euan K. James, Gail P. Ferguson

Faculty Publications

Sinorhizobium meliloti is a beneficial legume symbiont, closely related to Brucella species, which are chronic mammalian pathogens. We discovered that the S. meliloti MsbA2 protein is essential to ensure the symbiotic interaction with the host plant, alfalfa. S. meliloti invades plant cells via plant-derived structures known as infection threads. However, in the absence of MsbA2, S. meliloti remains trapped within abnormally thickened infection threads and induces a heightened plant defence response, characterized by a substantial thickening of the nodule endodermis layer and the accumulation of polyphenolic compounds. The S. meliloti MsbA2 protein is homologous to the Escherichia coli lipopolysaccharide/phospholipid trafficking …

Transmission Through A Thick Periodic Slab, Karim Ramdani, Stephen Shipman Apr 2008

Transmission Through A Thick Periodic Slab, Karim Ramdani, Stephen Shipman

Faculty Publications

For the scalar wave equation in periodic structures, we establish rigorously the manifestation of a spectral bandgap as a frequency interval of exponentially small transmission of energy through a slab of the crystal when the thickness of the slab tends to infinity. We extend the result to slabs that contain a planar defect for frequencies that do not coincide with guided mode frequencies for the defect. For one-dimensional crystals, we prove that the transmission approaches a nonzero value at guided mode frequencies and give an explicit formula for the transmission. The main analytical tool in the multidimensional case is the …

Synthesis And In Vitro Properties Of Trimethylamine- And Phosphonate-Substituted Carboranylporphyrins For Application In Bnct, Michael W. Easson, Frank R. Fronczek, Timothy J. Jensen, M. Graça H. Vicente

Faculty Publications

A series of carboranylporphyrins containing either amine or phosphonic acid functionalities and two to six closo-carborane clusters have been synthesized via a [2 + 2] condensation of a dimethylamino- or diethylphosphonate-substituted dipyrromethane with a dicarboranylmethyl-benzaldehyde. The X-ray structures of four key reaction intermediates (1, 2, 3, and 4a) and of two target porphyrins, the diphosphonate ester- and the diamino-tetracarboranylporphyrins 5b and 6a, are presented and discussed. In vitro studies using human carcinoma HEp2 and human glioblastoma T98G cells show that these porphyrins are non-toxic in the dark up to 100 μM concentrations, and that a tetracarboranylporphyrin bearing two quaternary ammonium …

A Natural Series For The Natural Logarithm, Oliver T. Dasbach Mar 2008

A Natural Series For The Natural Logarithm, Oliver T. Dasbach

Faculty Publications

Rodriguez Villegas expressed the Mahler measure of a polynomial in terms of an infinite series. Luck's combinatorial L2-torsion leads to similar series expressions for the Gromov norm of a knot complement. In this note we show that those formulae yield interesting power series expansions for the logarithm function. This generalizes an infinite series of Lehmer for the natural logarithm of 4.

Determination Of Enantiomeric Compositions Of Analytes Using Novel Fluorescent Chiral Molecular Micelles And Steady State Fluorescence Measurements, Alicia A. Williams, Sayo O. Fakayode, Onur Alptürk, Christina M. Jones, Mark Lowry, Robert M. Strongin, Isiah M. Warner Mar 2008

Determination Of Enantiomeric Compositions Of Analytes Using Novel Fluorescent Chiral Molecular Micelles And Steady State Fluorescence Measurements, Alicia A. Williams, Sayo O. Fakayode, Onur Alptürk, Christina M. Jones, Mark Lowry, Robert M. Strongin, Isiah M. Warner

Faculty Publications

Novel fluorescent chiral molecular micelles (FCMMs) were synthesized, characterized, and employed as chiral selectors for enantiomeric recognition of non-fluorescent chiral molecules using steady state fluorescence spectroscopy. The sensitivity of the fluorescence technique allowed for investigation of low concentrations of chiral selector (3.0∈×∈10 -5 M) and analyte (5.0∈×∈10 -6 M) to be used in these studies. The chiral interactions of glucose, tartaric acid, and serine in the presence of FCMMs poly(sodium N-undecanoyl-l-tryptophanate) [poly-l-SUW], poly(sodium N-undecanoyl-l-tyrosinate) [poly-l-SUY], and poly(sodium N-undecanoyl-l- phenylalininate) [poly-SUF] were based on diastereomeric complex formation. Poly-l-SUW had a significant fluorescence emission spectral difference as compared to poly-l-SUY and poly-l-SUF …

Faculty Publications

The hydroxyalkylation reactions of aceanthrenequinone (6) and acenapthenequinone (7) with a series of arenes have been studied. In reactions with the Brønsted superacid CF3SO3H (triflic acid), the condensation products are formed in good yields (58-99%, 10 examples) with high regioselectivity. Computational studies were also done to examine the structures and energies of mono- and diprotonated species from 6 and 7. The results from the condensation reactions are consistent with the formation of superelectrophilic species involving protosolvation of carboxonium ion intermediates. © 2007 Elsevier B.V.

Lejeune, Jie Ren Li, Brian R. Lewandowski, Wilson K. Serem, Stephanie L. Daniels, Kathie L. Lusker, Jayne C. Garno

Faculty Publications

Nanografting is a high-precision approach for scanning probe lithography, which provides unique advantages and capabilities for rapidly writing arrays of nanopatterns of thiol self-assembled monolayers (SAMs). Nanografting is accomplished by force-induced displacement of molecules of a matrix SAM, followed immediately by the self-assembly of n-alkanethiol ink molecules from solution. The feedback loop used to control the atomic force microscope tip position and displacement enables exquisite control of forces applied to the surface, ranging from pico to nanonewtons. To achieve high-resolution writing at the nanoscale, the writing speed, direction, and applied force need to be optimized. There are strategies for programing …

We report the synthesis and characterization of amino acid ester based chiral ionic liquids, derived from L- and D-alanine tert butyl ester chloride. The synthesis was accomplished via an anion metathesis reaction between commercially available L-and D-alanine tert butyl ester chloride using a variety of counterions such as lithium bis (trifluoromethane) sulfonimide, silver nitrate, silver lactate, and silver tetrafluoroborate. Both enantiomeric forms were obtained as confirmed by bands of opposite sign in the circular dichroism spectra. The L- and D-alanine tert butyl ester bis (trifluoromethane) sulfonimide were obtained as liquids at room temperature and intriguingly exhibited the highest thermal stability …

The observation of neutrino oscillations is clear evidence for physics beyond the standard model. To make precise measurements of this phenomenon, neutrino oscillation experiments, including MiniBooNE, require an accurate description of neutrino charged current quasielastic (CCQE) cross sections to predict signal samples. Using a high-statistics sample of νμ CCQE events, MiniBooNE finds that a simple Fermi gas model, with appropriate adjustments, accurately characterizes the CCQE events observed in a carbon-based detector. The extracted parameters include an effective axial mass, MAeff=1.23±0. 20GeV, that describes the four-momentum dependence of the axial-vector form factor of the nucleon, and a Pauli-suppression parameter, κ=1. 019±0.011. …
