Fast Photometry Of Quiescent Soft X-Ray Transients With The Acquisition Camera On Gemini-South, R. I. Hynes, P. A. Charles, J. Casares, C. A. Haswell, C. Zurita, T. Shahbaz

Faculty Publications

We present a compilation of high time-resolution photometric observations of quiescent soft X-ray transients obtained with the Acquisition Camera on Gemini-South. A0620-00 (V616 Mon) was observed with a short cycle time and high precision. Superimposed on the ellipsoidal modulation we find several prominent flares together with weaker continual variability. The flares seen sample a shorter time-scale than those reported in previous observations, with rise times as low as 30 s or less; most flares show unresolved peaks. The power density spectrum (PDS) of A0620-00 appears to exhibit band-limited noise closely resembling the X-ray PDS of black hole candidates in their …

Interstrain Inhibition In The Sweet Potato Pathogen Streptomyces Ipomoeae: Purification And Characterization Of A Highly Specific Bacteriocin And Cloning Of Its Structural Gene, Xiujun Zhang, Christopher A. Clark, Gregg S. Pettis

Faculty Publications

Strains of the sweet potato soil rot pathogen Streptomyces ipomoeae had previously been divided into three groups based on their ability to inhibit one another during pairwise cocultivation. While group I strains are not antagonistic to members of the other groups, group II and group III strains produce separate substances that are inhibitory to strains outside their respective cognate groups. Here, we purified the group III inhibitory substance from the culture supernatant of a representative strain and found that it consists of a single 10-kDa cationic protein which is bacteriolytic for S. ipomoeae group I and II strains but which …

Y Chromosome Str Haplotypes And The Genetic Structures Of U.S. Populations Of African, European, And Hispanic Ancestry, Manfred Kayser, Silke Brauer, Hiltrud Schädlich, Mechthild Prinz, Mark A. Batzer, Peter A. Zimmerman, B. A. Boatin, Mark Stoneking

Faculty Publications

To investigate geographic structure within U.S. ethnic populations, we analyzed 1705 haplotypes on the basis of 9 short tandem repeat (STR) loci on the Y-chromosome from 9-11 groups each of African-Americans, European-Americans, and Hispanics. There were no significant differences in the distribution of Y-STR haplotypes among African-American groups, whereas European-American and Hispanic groups did exhibit significant geographic heterogeneity. However, the significant heterogeneity resulted from one sample; removal of that sample in each case eliminated the significant heterogeneity. Multidimensional scaling analysis of RST values indicated that African-American groups formed a distinct cluster, whereas there was some intermingling of European-American and Hispanic …

Unitary Representations And Theta Correspondence For Type I Classical Groups, Hongyu He

Faculty Publications

In this paper, we discuss the positivity of the Hermitian form (,)π introduced by Li in Invent. Math. 27 (1989) 237-255. Let (G1, G2) be a type I dual pair with G1 the smaller group. Let π be an irreducible unitary representation in the semistable range of θ(MG1, MG2) (see Communications in Contemporary Mathematics, Vol. 2, 2000, pp. 255-283). We prove that the invariant Hermitian form (,)π is positive semidefinite under certain restrictions on the size of G2 and a mild growth condition on the matrix coefficients of π. Therefore, if (,)π does not vanish, θ(MG1, MG2) (π) is unitary. …

Inhibition Of Heparanase Activity And Heparanase-Induced Angiogenesis By Suramin Analogues, Dario Marchetti, Jane Reiland, Brad Erwin, Madhuchhanda Roy

Faculty Publications

Heparanase, a heparan sulfate-specific endo-β-D-glucuronidase, plays an important role in tumor cell metastasis through the degradation of extracellular matrix heparan sulfate proteoglycans (ECM HSPG). Heparanase activity correlates with the metastatic propensity of tumor cells. Suramin, a polysulfonated naphthylurea, is an inhibitor of heparanase with suramin analogues shown to possess antiangiogenic and antiproliferative properties. We investigated the effects of selected suramin analogues (NF 127, NF 145 and NF 171) on heparanase activity and heparanase-driven angiogenesis. Studies of the ability of cellular extracts and purified heparanase from human, highly invasive and brain-metastatic melanoma (70W) cells revealed that heparanase expressed by these cells …

A Causative Relationship Exists Between Eosinophils And The Development Of Allergic Pulmonary Pathologies In The Mouse, Hua Hao H. Shen, Sergei I. Ochkur, Michael P. Mcgarry, Jeffrey R. Crosby, Edie M. Hines, Michael T. Borchers, Huiying Wang, Travis L. Biechelle, Katie R. O'Neill, Tracy L. Ansay, Dana C. Colbert, Stephania A. Cormier, J. Paul Justice, Nancy A. Lee, James J. Lee

Faculty Publications

Asthma and mouse models of allergic respiratory inflammation are invariably associated with a pulmonary eosinophilia; however, this association has remained correlative. In this report, a causative relationship between eosinophils and allergen-provoked pathologies was established using eosinophil adoptive transfer. Eosinophils were transferred directly into the lungs of either naive or OVA-treated IL-5-/- mice. This strategy resulted in a pulmonary eosinophilia equivalent to that observed in OVA-treated wild-type animals. A concomitant consequence of this eosinophil transfer was an increase in Th2 bronchoalveolar lavage cytokine levels and the restoration of intracellular epithelial mucus in OVA-treated IL-5-/- mice equivalent to OVA-treated wild-type levels. Moreover, …

Stabilizing The Open Conformation Of The Integrin Headpiece With A Glycan Wedge Increases Affinity For Ligand, Bing Hao Luo, Timothy A. Springer, Junichi Takagi

Faculty Publications

The affinity of the extracellular domain of integrins for ligand is regulated by conformational changes signaled from the cytoplasm. Alternative types of conformational movement in the ligandbinding headpiece have been proposed. In one study, electron micrograph image averages of the headpiece of integrin aVβ3 show two different conformations. The open conformation of the headpiece is present when a ligand mimetic peptide is bound and differs from the closed conformation in the presence of an obtuse angle between the β3 subunit hybrid and I-like domains. We tested the hypothesis that opening of the hybrid-I-like domain interface increases ligand-binding affinity by mutationally …
