A 5'-Upstream Short Open Reading Frame Encoded Peptide Regulates Angiotensin Type 1a Receptor Production And Signalling Via The Β-Arrestin Pathway, Gina L.C. Yosten, Jun Liu, Hong Ji, Kathryn Sandberg, Robert Speth, Willis K. Samson Mar 2016

A 5'-Upstream Short Open Reading Frame Encoded Peptide Regulates Angiotensin Type 1a Receptor Production And Signalling Via The Β-Arrestin Pathway, Gina L.C. Yosten, Jun Liu, Hong Ji, Kathryn Sandberg, Robert Speth, Willis K. Samson

Biological Sciences Faculty Research & Creative Works

AUG sequences and short open reading frames are commonly present in the 5'-leader sequence of G protein-coupled receptor mRNAs. The presence of these upstream AUG sequences has been demonstrated to inhibit downstream receptor translation efficiency and, most recently, receptor signal transduction. A seven amino acid peptide encoded by a short open reading frame in exon 2 of the angiotensin type 1a receptor has been shown to inhibit non-G protein-coupled signaling of angiotensin II, without altering the classical G protein-coupled pathway activated by the ligand. This finding may lead to the development of a new class of angiotensin receptor antagonists with …

Evaluation Of Carbonation Resistance Of Paint Coated Concrete For Buildings, Tommy Y. Lo, Wenyu Liao, C. K. Wong, Waiching Tang Mar 2016

Evaluation Of Carbonation Resistance Of Paint Coated Concrete For Buildings, Tommy Y. Lo, Wenyu Liao, C. K. Wong, Waiching Tang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

When evaluating the carbonation resistance of paint coated concrete, the effects of both the strength grade and the curing conditions (standard curing and accelerated curing) of concrete substrate on carbonation resistance of paint coated concrete were investigated. The concept of the carbonation suppression ratio of paint was presented for evaluation of the anti-carbonation performance of the two types of paints (exterior and interior paints) when applied to a reference concrete substrate. The test results showed a good linear relationship between the carbonation depths of the paint coated concrete and the square root of exposure times. Concrete with higher strength grade …

Throughput Optimisation For Energy Harvesting Transmitter With Partial Instantaneous Channel State Information And Finite-Alphabet Inputs, Xiaodong Zhu, Weiliang Zeng, Chengshan Xiao Mar 2016

Throughput Optimisation For Energy Harvesting Transmitter With Partial Instantaneous Channel State Information And Finite-Alphabet Inputs, Xiaodong Zhu, Weiliang Zeng, Chengshan Xiao

Electrical and Computer Engineering Faculty Research & Creative Works

Wireless communication systems with energy harvester are attracting much attention due to their ability to improve the system operation time. Extensive research has been carried out on how to maximize the sum of mutual information over multiple time slots (i.e. the throughput). However, most research focuses on the energy harvesting transmitter with Gaussian inputs and single antenna. This study considers the throughput maximization problem for an energy harvesting transmitter with causal energy constraint over multiple-input multiple-output (MIMO) channels. Different from existing works, the authors consider the MIMO system with finite-alphabet inputs and partial instantaneous channel state information (CSI). Specifically, the …

Identification Of A Short Cell-Penetrating Peptide From Bovine Lactoferricin For Intracellular Delivery Of Dna In Human A549 Cells, Betty Revon Liu, Yue-Wern Huang, Robert Aronstam, Han-Jung Lee Mar 2016

Identification Of A Short Cell-Penetrating Peptide From Bovine Lactoferricin For Intracellular Delivery Of Dna In Human A549 Cells, Betty Revon Liu, Yue-Wern Huang, Robert Aronstam, Han-Jung Lee

Biological Sciences Faculty Research & Creative Works

Cell-penetrating peptides (CPPs) have been shown to deliver cargos, including protein, DNA, RNA, and nanomaterials, in fully active forms into live cells. Most of the CPP sequences in use today are based on non-native proteins that may be immunogenic. Here we demonstrate that the L5a CPP (RRWQW) from bovine lactoferricin (LFcin), stably and noncovalently complexed with plasmid DNA and prepared at an optimal nitrogen/phosphate ratio of 12, is able to efficiently enter into human lung cancer A549 cells. The L5a CPP delivered a plasmid containing the enhanced green fluorescent protein (EGFP) coding sequence that was subsequently expressed in …

Adropin Acts In Brain To Inhibit Water Drinking: Potential Interaction With The Orphan G Protein-Coupled Receptor, Gpr19, Lauren M. Stein, Gina L.C. Yosten, Willis K. Samson Mar 2016

Adropin Acts In Brain To Inhibit Water Drinking: Potential Interaction With The Orphan G Protein-Coupled Receptor, Gpr19, Lauren M. Stein, Gina L.C. Yosten, Willis K. Samson

Biological Sciences Faculty Research & Creative Works

Adropin, a recently described peptide hormone produced in the brain and liver, has been reported to have physiologically relevant actions on glucose homeostasis and lipogenesis, and to exert significant effect on endothelial function. We describe a central nervous system action of adropin to inhibit water drinking and identify a potential adropin receptor, the orphan G protein-coupled receptor, GPR19. Reduction in GPR19 mRNA levels in medial basal hypothalamus of male rats resulted in the loss of the inhibitory effect of adropin on water deprivation-induced thirst. The identification of a novel brain action of adropin and a candidate receptor for the peptide …

Biological Sciences Faculty Research & Creative Works

To investigate age-associated impairments in fluid homeostasis, 4-mo (young) and 32-mo (old) Fischer 344/BN male rats were studied before and after a dietary sodium load. Transferring young rats from a low-sodium (LS) to a high-sodium (HS) diet increased water intake and urine volume by 1.9-and 3.0-fold, respectively, while urine osmolality and plasma aldosterone decreased by 33 and 98%. Concomitantly, adrenocortical angiotensin type 1 receptor (AT1R) density decreased by 35%, and AT1bR mRNA decreased by 39%; no changes were observed in AT1aR mRNA. In contrast, the increase in water intake (1.4-fold) was lower in the old rats, and there was no …

Retrieving Transient Conformational Molecular Structure Information From Inner-Shell Photoionization Of Laser-Aligned Molecules, Xu Wang, Anh-Thu Le, Chao Yu, R. R. Lucchese, C. D. Lin Mar 2016

Retrieving Transient Conformational Molecular Structure Information From Inner-Shell Photoionization Of Laser-Aligned Molecules, Xu Wang, Anh-Thu Le, Chao Yu, R. R. Lucchese, C. D. Lin

Physics Faculty Research & Creative Works

We discuss a scheme to retrieve transient conformational molecular structure information using photoelectron angular distributions (PADs) that have averaged over partial alignments of isolated molecules. The photoelectron is pulled out from a localized inner-shell molecular orbital by an X-ray photon. We show that a transient change in the atomic positions from their equilibrium will lead to a sensitive change in the alignment-averaged PADs, which can be measured and used to retrieve the former. Exploiting the experimental convenience of changing the photon polarization direction, we show that it is advantageous to use PADs obtained from multiple photon polarization directions. A simple …

Shape Dependence Of Transmission, Reflection, And Absorption Eigenvalue Densities In Disordered Waveguides With Dissipation, Alexey Yamilov, Sasha Petrenko, Raktim Sarma, Hui Cao Mar 2016

Shape Dependence Of Transmission, Reflection, And Absorption Eigenvalue Densities In Disordered Waveguides With Dissipation, Alexey Yamilov, Sasha Petrenko, Raktim Sarma, Hui Cao

Physics Faculty Research & Creative Works

The universal bimodal distribution of transmission eigenvalues in lossless diffusive systems underpins such celebrated phenomena as universal conductance fluctuations, quantum shot noise in condensed matter physics, and enhanced transmission in optics and acoustics. Here, we show that in the presence of absorption, the density of the transmission eigenvalues depends on the confinement geometry of the scattering media. Furthermore, in an asymmetric waveguide, the densities of the reflection and absorption eigenvalues also depend on the side from which the waves are incident. With increasing absorption, the density of absorption eigenvalues transforms from a single-peak to a double-peak function. Our findings open …

Scale Effect Of Premixed Methane-Air Combustion In Confined Space Using Les Model, Liang Wang, Sisi Que, Jerry C. Tien, Nassib Aouad Mar 2016

Scale Effect Of Premixed Methane-Air Combustion In Confined Space Using Les Model, Liang Wang, Sisi Que, Jerry C. Tien, Nassib Aouad

Mining Engineering Faculty Research & Creative Works

Gas explosion is the most hazardous incident occurring in underground airways. Computational Fluid Dynamics (CFD) techniques are sophisticated in simulating explosions in confined spaces; specifically, when testing large-scale gaseous explosions, such as methane explosions in underground mines. The dimensions of a confined space where explosions could occur vary significantly. Thus, the scale effect on explosion parameters is worth investigating. In this paper, the impact of scaling on explosion overpressures is investigated by employing two scaling factors: The Gas-fill Length Scaling Factor (FLSF) and the Hydraulic Diameter Scaling Factor (HDSF). The combinations of eight FLSFs and five HDSFs will cover a …

The presence of emerging micropollutants such as pharmaceuticals, endocrine disruptors, personal care products, nanomaterials and perfluorinated substances in the environment remains a great threat to the health and safety of humans and aquatic species. These micropollutants enter the environment via anthropogenic activities and have been detected in surface water, groundwater and even drinking water at nanogram per liter to microgram per liter concentration. To date, limited information exists on the fate, behaviors, and pathways of these micropollutants in the environment. The potential ecotoxicological effects on the receptors due to exposure to individual or mixture of these chemicals still remain unknown. …

Gw150914: Implications For The Stochastic Gravitational-Wave Background From Binary Black Holes, Benjamin P. Abbott, Marco Cavaglia, For Full List Of Authors, See Publisher's Website.

Physics Faculty Research & Creative Works

The LIGO detection of the gravitational wave transient GW150914, from the inspiral and merger of two black holes with masses ≳30M⊙, suggests a population of binary black holes with relatively high mass. This observation implies that the stochastic gravitational-wave background from binary black holes, created from the incoherent superposition of all the merging binaries in the Universe, could be higher than previously expected. Using the properties of GW150914, we estimate the energy density of such a background from binary black holes. In the most sensitive part of the Advanced LIGO and Advanced Virgo band for stochastic backgrounds (near …

Dirac Hamiltonian And Reissner-Nordström Metric: Coulomb Interaction In Curved Space-Time, J. H. Noble, Ulrich D. Jentschura Mar 2016

Dirac Hamiltonian And Reissner-Nordström Metric: Coulomb Interaction In Curved Space-Time, J. H. Noble, Ulrich D. Jentschura

Physics Faculty Research & Creative Works

We investigate the spin-1/2 relativistic quantum dynamics in the curved space-time generated by a central massive charged object (black hole). This necessitates a study of the coupling of a Dirac particle to the Reissner-Nordström space-time geometry and the simultaneous covariant coupling to the central electrostatic field. The relativistic Dirac Hamiltonian for the Reissner-Nordström geometry is derived. A Foldy-Wouthuysen transformation reveals the presence of gravitational and electrogravitational spin-orbit coupling terms which generalize the Fokker precession terms found for the Dirac-Schwarzschild Hamiltonian, and other electrogravitational correction terms to the potential proportional to αnG, where α is the fine-structure constant and …

The Mantle Transition Zone Beneath The Afar Depression And Adjacent Regions: Implications For Mantle Plumes And Hydration, Cory A. Reed, Stephen S. Gao, Kelly H. Liu, Y. Yu

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

The Afar Depression and its adjacent areas are underlain by an upper mantle marked by some of the world's largest negative velocity anomalies, which are frequently attributed to the thermal influences of a lower-mantle plume. In spite of numerous studies, however, the existence of a plume beneath the area remains enigmatic, partially due to inadequate quantities of broad-band seismic data and the limited vertical resolution at the mantle transition zone (MTZ) depth of the techniques employed by previous investigations. In this study, we use an unprecedented quantity (over 14 500) of P-to-S receiver functions (RFs) recorded by 139 stations from …
