Opalek, Judy M.; Ali, Naeem A.; Lobb, Jennifer M.; Hunter, Melissa G.; Marsh, Clay B. ( 2007-09-22 )Background: The recruitment of mononuclear cells has important implications for tissue inflammation. Previous studies demonstrated enhanced CCR1 and CCR5 expression and decreased CCR2 expression during in vitro monocyte ... -
Alzheimer's Amyloid-β is an Antimicrobial Peptide: A Review of the Evidence
Gosztyla, Maya; Brothers, Holly; Robinson, Stephen ( 2018-03-27 )The amyloid-β (Aβ) peptide has long been considered to be the driving force behind Alzheimer’s disease (AD). However, clinical trials that have successfully reduced Aβ burden in the brain have not slowed the cognitive ... -
Amyloidosis in cheetahs (Acinonyx jubatus), transmissible?
McLean, Kanyon; Garabed, Rebecca; Wolfe, Barbara ( 2015-04-02 )Amyloidosis causes pathology through the accumulation of misfolded amyloid A protein in visceral organs, often leading to death of the animal. The increase of amyloidosis in captive cheetahs is of grave concern for the ... -
Analysis of a Proper-Motion-Selected Sample of Stars in the Ursa Minor Dwarf Spheroidal Galaxy
Eskridge, Paul B.; Schweitzer, Andrea E. ( 2001-12 )We have studied the stellar population and internal structure of the core of the Ursa Minor dwarf spheroidal galaxy, using a sample of stars selected to be members based on their proper motions. In agreement with previous ... -
Analytic Study of Grid Star and Reference Star Selection for the Space Interferometry Mission
Gould, Andrew ( 2001-09-20 )Grid stars and reference stars provide the fundamental global and local astrometric reference frames for observations by the Space Interferometry Mission. They must therefore be astrometrically stable at the ~1 μas level. ... -
Angular Momentum Transport in Solar-Type Stars: Testing the Timescale for Core-Envelope Coupling
Denissenkov, Pavel A.; Pinsonneault, Marc; Terndrup, Donald M.; Newsham, Grant ( 2010-06-20 )We critically examine the constraints on internal angular momentum transport which can be inferred from the spin-down of open cluster stars. The rotation distribution inferred from rotation velocities and periods is ... -
Animals in Ohio long-term care facilities
Stull, Jason; Landers, Tim; Fauver, Chelsea ( 2016 )There is strong evidence that animals provide many health benefits to residents living in a long-term care facility (Nursing Home). Although animals may provide benefits to this population, there are also health risks ... -
Anisotropic Flow and Jet Quenching in Ultrarelativistic U+U Collisions
Heinz, Ulrich; Kuhlman, Anthony ( 2005-04-06 )Full-overlap U+U collisions provide significantly larger initial energy densities at comparable spatial deformation, and significantly larger deformation and volume at comparable energy density, than semicentral Au+Au ... -
Anisotropic Line Emission and the Geometry of the Broad-Line Region in Active Galactic Nuclei
Nahar, Sultana Nurun; Ferland, G. J.; Peterson, B. M.; Horne, K.; Welsh, W. F. ( 1992-03 )The rapid response of the broad emission lines to continuum variations in the Seyfert galaxy NGC 5548 implies that line-emitting regions are very close to the continuum source. As described in this contribution, photoionization ... -
Anomalous dispersion in the autocorrelation of angle-resolved photoemission spectra of high-temperature Bi_2Sr_2CaCu_2O_8+δ superconductors
Chatterjee, U.; Shi, M.; Kaminski, A.; Kanigel, A.; Fretwell, H. M.; Terashima, K.; Takahashi, T.; Rosenkranz, S.; Li, Z. Z.; Raffy, H.; Santander-Syro, A.; Kadowaki, K.; Randeria, M.; Norman, M. R.; Campuzano, J. C. ( 2007-07-23 )We find that peaks in the autocorrelation of angle-resolved photoemission spectroscopy data of Bi_2Sr_2CaCu_2O_8+δ in the superconducting state show dispersive behavior for binding energies smaller than the maximum ... -
Anomalous Noise in the Pseudogap Regime of YBa_2Cu_3O_7-δ
Caplan, D. S.; Orlyanchik, V.; Weissman, M. B.; Harlingen, D. J. Van; Fradkin, E. H.; Hinton, M. J.; Lemberger, T. R. ( 2010-04-26 )An unusual noise component is found near and below about 250 K in the normal state of underdoped YBCO and Ca-YBCO films. This noise regime, unlike the more typical noise above 250 K, has features expected for a symmetry-breaking ... -
Anomalously sharp superconducting transitions in overdoped La_2−xSr_xCuO_4 films
Lemberger, T. R.; Hetel, I.; Tsukada, A.; Naito, M. ( 2010-12-16 )We present measurements of ab-plane resistivity ρ_ab(T) and superfluid density (n_s∝λ^−2, λ=magnetic penetration depth) in La_2−xSr_xCuO_4 (LSCO) films. As Sr concentration x exceeds about 0.22, the superconducting ... -
Anomaly in photoelectron angular distributions
Zhang, Jingtao; van Woerkom, L. D.; Guo, Dong-Sheng; Freeman, R. R. ( 2007-07-27 )The recently observed anomaly in photoelectron angular distributions (PADs), the disappearance of the main lobes of PADs which should be usually in the direction of laser polarization, is reinterpreted as a minimum of ... -
Anopheles gambiae heat shock protein cognate 70B impedes o'nyong-nyong virus replication
Sim, Cheolho; Hong, Young S.; Tsetsarkin, Konstantin A.; Vanlandingham, Dana L.; Higgs, Stephen; Collins, Frank H. ( 2007-07-11 )Background Phylogenetic and functional analysis was conducted on an Anopheles gambiae gene, ENSANGG00000017398. Based on phylogenetic analysis, this gene belongs to the same lineage as Heat shock protein cognate 70-4 ... -
Anthropogenic resource subsidies decouple predator–prey relationships
Rodewald, Amanda D.; Kearns, Laura J.; Shustack, Daniel P. ( 2011-04 )The extent to which resource subsidies affect food web dynamics is poorly understood in anthropogenic landscapes. To better understand how species interactions are influenced by subsidies, we studied breeding birds and ... -
