The Glucose Metabolite Methylglyoxal Inhibits Expression Of The Glucose Transport Genes By Inactivating The Cell Surface Glucose Sensors Rgt2 And Snf3 In Yeast, Adhiraj Roy, Salman Hashmi, Zerui Li, Angela Dement, Kyu Hong Cho, Jeong-Ho Kim

Biochemistry and Molecular Medicine Faculty Publications

Methylglyoxal (MG) is a cytotoxic by-product of glycolysis. MG has inhibitory effect on the growth of cells ranging from microorganisms to higher eukaryotes, but its molecular targets are largely unknown. The yeast cell-surface glucose sensors Rgt2 and Snf3 function as glucose receptors that sense extracellular glucose and generate a signal for induction of expression of genes encoding glucose transporters (HXTs). Here we provide evidence that these glucose sensors are primary targets of MG in yeast. MG inhibits the growth of glucose-fermenting yeast cells by inducing endocytosis and degradation of the glucose sensors. However, the glucose sensors with mutations …

Establishment Of Prostate Cancer Spheres From A Prostate Cancer Cell Line After Phenethyl Isothiocyanate Treatment And Discovery Of Androgen-Dependent Reversible Differentiation Between Sphere And Neuroendocrine Cells, Yamei Chen, Shundong Cang, Liying Han, Christina Liu, Patrick Yang, Zeeshan Solangi, Quanyi Lu, Delong Liu, Jenwei Chiao

NYMC Faculty Publications

Prostate cancer can transform from androgen-responsive to an androgen-independent phenotype. The mechanism responsible for the transformation remains unclear. We studied the effects of an epigenetic modulator, phenethyl isothiocyanate (PEITC), on the androgen-responsive LNCaP cells. After treatment with PEITC, floating spheres were formed with characteristics of prostate cancer stem cells (PCSC). These spheres were capable of self-renewal in media with and without androgen. They have been maintained in both types of media as long term cultures. Upon androgen deprivation, the adherent spheres differentiated to neuroendocrine cells (NEC) with decreased proliferation, expression of androgen receptor, and PSA. NEC reverse differentiated to spheres …

Ecological degradation of the benthic littoral zone is an emerging, urgent problem at Lake Baikal (East Siberia), the most species-rich lake on Earth. Within the last five years, multiple changes have occurred in the nearshore benthos where most of the lake's endemic species reside. These changes include proliferation of benthic algae, deaths of snails and endemic sponges, large coastal wash-ups of dead benthic algae and macrophytes, blooms of toxin-producing benthic cyanobacteria, and inputs of industrial contaminants into parts of the lake. Some changes, such as massive coastal accumulations of benthic algae, are currently shared with the Laurentian Great Lakes (LGLs); …

A Ph Sensor For Non-Invasive In Vivo Detection And Imaging Of Implant Associated Infection, Unaiza Uzair, Donald Benza, Fenglin Wang, Yash Raval, Tzuen-Rong J. Tzeng, Jeffrey N. Anker

Chemistry Annual Research Symposium

We develop a pH sensor based on use of X-ray Excited Luminescence Chemical Imaging (XELCI) to non-invasively detect and image changes in pH of a surface with high spatial and pH resolution while minimizing tissue scattering effects. Diagnosis and treatment of infections associated with implanted medical devices is a challenge, as clinical symptoms of implant associated infection are often delayed and can sometimes be completely absent till infection reaches a later stage. Early diagnosis of implant associated infection and non-invasive continuous monitoring of infection to evaluate eradication and success of treatment has not been established yet. Treatment of implant infection …

Developing A Safe Test System For High-Energy Electron Flux Environments Testing, Heather Tippets

Senior Theses and Projects

In order to predict and mitigate adverse environmental effects on spacecraft in orbit about Earth, a versatile pre-launch test capability for assessment and verification of small satellites, systems, and components was developed by Utah State University’s Materials Physics Group. To further diversify this project, a 100 mCi Sr-90 beta radiation source (0.5 MeV – 2.5 MeV) is exploited to simulate the high energy electron flux of geostationary orbit. Various samples including in-the-loop hardware, spacecraft materials, optical components, and solar arrays are irradiated to gain a better understanding of how these materials and electronics break down in space environments. For employee …

Characterizing A Debris Field Using Digital Mosaicking And Cad Model Superimposition From Underwater Video, Jay M. Vincelli, Fatih Calakli, Michael A. Stone, Graham E. Forrester, Timothy Mellon, John D. Jarrell

Natural Resources Science Faculty Publications

Identifying submerged objects is critical for several disciplines such as marine archaeology and search and rescue. However, identifying objects in underwater searches presents many challenges, particularly if the only data available to analyze is poorquality video where the videographer did not plan for photogrammetric techniques to be utilized. In this paper, we discuss the use of adaptive sampling of the underwater video to extract sharp still images for stitching and analysis, and creating mosaicked images by identifying and matching local scale-invariant feature transform features using computationally efficient algorithms. Computer aided design models of suspected aircraft components were superimposed, and a …

The Effect Of Xenon Pulsed-Light Technology On Biofilm Adhered To Stainless Steel Surfaces, Stephanie Jacquez

Master's Theses

In food processing, inadequate surface sanitation procedures lead to the formation of biofilms in which bacteria attach and aggregate in a hydrated polymeric matrix of their own synthesis. Formation of these sessile communities and their inherent resistance to existing sanitation procedures and agents are at the root of the risk of bacterial infections for consumers. Due to this existing problem, an effective method for reducing biofilm formation in dairy processing equipment is necessary for dairy products processing. Ultraviolet Pulsed light Technology has shown a positive effect in eliminating microorganism populations on food products. The objective of this work is to …

On The Rotation And Axial Magnetic Field Effects Of A Non-Homogeneous Composite Infinite Cylinder Of Orthotropic Material, S. M. Abo-Dahab, Nahed S. Hussein, H. A. Alshehri

Applied Mathematics & Information Sciences

In this paper, the rotation and magnetic field effects problem on an orthotropic cylinder containing: (i) an isotropic core and (ii) a rigid core; is considered. The elastic constants and density are taken as a power function of the radial coordinate. Analytical expressions for components of the displacement, radial, hoop and axial stresses in different cases are obtained. The results obtained are illustrated numerically. A comparison between both cases are clarified numerically and then presented graphically.

In the beginning, twenty four variables are chosen from Fatal Traffic Accident data set. Later, dimension reduction is used to reduce the number of variables from twenty four to nine variables by principal component analysis. With two different CRT models with twenty four and nine variables to forecast injury severity, a comparison is made in terms of rules generated, model accuracy, type I and type II errors, and evaluation chart generated by …

Effect Of Partial Slip On Peristaltic Flow Of A Sisko Fluid With Mild Stenosis Through A Porous Medium, Nabil T. M. El-Dabe, Galal M. Moatimid, Mohamed A. Hassan, Doaa R. Mostapha

Applied Mathematics & Information Sciences

This paper investigates the effect of partial slip on peristaltic flow of a Sisko fluid through a porous medium. The flow is streaming through a tapered artery having a mild stenosis. The influences of heat and chemical reactions on blood flow are also taken into account. The governing equations of motion, energy and concentration are simplified by using the long wavelength and low Reynolds number approximations. The analytical solutions of these equations are obtained by considering a perturbation technique for small non- Newtonian Sisko fluid parameter. The pressure rise and friction force are numerically calculated. The numerical calculations with the …

Solitary Solutions For Some Nonlinear Evolution Equations Using Bernoulli Method, A. Hussein

Applied Mathematics & Information Sciences

New solitary solutions of some nonlinear partial differential equations are constructed using the generalized Bernoulli method. The main idea of this method is to make use of Bernoulli differential equation which has a simple exponential solution. The ZK-BBM (Zakharov-Kuznetsov-Benjamin–Bona–Mahony), a nonlinear dispersive, and the general Burgers-Fisher equations are solved and numerically investigated. The ZK equation that describes two-dimensional, magnetized, collisionless pair ions plasma is also presented as a problem of physical interest. Comparisons with G’/G-expansion method are given for the sake of assessments of Bernoulli method. Successfully, this method not only gives new solitary solutions of the problems under consideration …

Hydrothermal Single Crystal Growth And Characterization Of Novel Rare Earth Niobates And Tantalates: Lnnbo4 (Ln = La-Lu , Y), La2tao5(Oh) And Ln3ta2o9(Oh), Liurukara D. Sanjeewa, Kyle Fulle, Colin D. Mcmillen, Joseph W. Kolis

Chemistry Annual Research Symposium

Rare-earth niobates and tantalates are refractory materials that have been exploited in applications involving ion conductivity, photo-catalysis, and luminescence, both in doped and un-doped forms.

In general, refractory oxides have high melting points therefore synthesis of single crystals are more challenging. For example LnNbO4 can be grown readily by melt techniques such as Czochralski pulling ~1300 ˚C. However during the cooling crystal quality degraded resulting low quality crystals therefore high temperature melting techniques are not suitable for bulk single crystals growth.

Recent Advances In The Synthesis And Application Of Sf5-Containing Organic Compounds, Andrej V. Matsnev, Steven P. Belina, Si-Yan Qing, Kyle A. Berger, Anthony R. Scavuzzo, Piotr Dudzinski, Anna-Lena Dreier, Günter Haufe, Joseph S. Thrasher

Chemistry Annual Research Symposium

It is well known that fluorinated molecules play an important role in daily life. For example, organic molecules bearing either a fluorine atom itself or a short polyfluorinated substituent such as mono-, difluoro-, and trifluoromethyl groups, or pentafluoroethyl and perfluoropropyl groups are already widely used in medicinal and agricultural chemistry. In contrast, molecules with long perfluorinated chains have found vast application in materials science. Among the fluorine-containing moieties, the pentafluorosulfanyl (SF5) substituent occupies a special place.1 The pentafluorosulfanyl group brings unique properties to organic compounds and often improves their biological activities due to the group’s high chemical and metabolic stability, …

Liquid Sampling-Atmospheric Pressure Glow Discharge Ion Source For Nonproliferation Of Nuclear Material, Edward Hoegg, R. Kenneth Marcus, Charles Barinaga, George Hager, David Koppenaal, Garret Hart

Chemistry Annual Research Symposium

An area of continuing intense interest has been the development of portable or fieldable (man-portable, luggable, or transportable) analytical instrumentation. One specific driver for portable or fieldable analytical instrumentation are the needs of the nuclear safeguards community for versatile, easy-to-use, in-field mass spectrometer systems for determining the 235U/238U isotope ratios in UF6 at enrichment facilities. In order to meet this demand the authors propose using a liquid sampling-atmospheric pressure glow discharge (LS-APGD) ion source, Fig 1.1-3 The LS-APGD was optimized for isotope ratio analysis to have a liquid flow rate of 30 uL min-1 a gas flow rate of 0.5 …

Osteoinductive Polyhipe Foams As Injectable Bone Grafts, J. L. Robinson, M. A. P. Mcenery, H. Pearce, M. E. Whitely, Dany J. Munoz Pinto, M. S. Hahn, H. Li, N. A. Sears, E. Cosgriff-Hernandez

Engineering Faculty Research

We have recently fabricated biodegradable polyHIPEs as injectable bone grafts and characterized the mechanical properties, pore architecture, and cure rates. In this study, calcium phosphate nanoparticles and demineralized bone matrix (DBM) particles were incorporated into injectable polyHIPE foams to promote osteoblastic differentiation of mesenchymal stem cells (MSCs). Upon incorporation of each type of particle, stable monoliths were formed with compressive properties comparable to control polyHIPEs. Pore size quantification indicated a negligible effect of all particles on emulsion stability and resulting pore architecture. Alizarin red calcium staining illustrated the incorporation of calcium phosphate particles at the pore surface, while picrosirius red …

Applied Mathematics & Information Sciences

In this article, a residual power series technique for the power series solution of systems of initial value problems is introduced. The new approach provides the solution in the form of a rapidly convergent series with easily computable components using symbolic computation software. The proposed technique obtains Taylor expansion of the solution of a system and reproduces the exact solution when the solution is polynomial. Numerical examples are included to demonstrate the efficiency, accuracy, and applicability of the presented technique. The results reveal that the technique is very effective, straightforward, and simple.

20-Hete Activates The Transcription Of Angiotensin-Converting Enzyme Via Nuclear Factor-Κb Translocation And Promoter Binding, Victor Garcia, Brian Shkolnik, Laura Milhau, John R. Falck, Michal Laniado Schwartzman

NYMC Faculty Publications

Increased vascular 20-hydroxyeicosatetraenoic acid (20-HETE), a cytochrome P450 arachidonic acid metabolite, promotes vascular dysfunction, injury, and hypertension that is dependent, in part, on the renin angiotensin system (RAS). We have shown that, in human microvascular endothelial cells, 20-HETE increases angiotensin-converting enzyme (ACE) mRNA, protein, and ACE activity via an epidermal growth factor receptor (EGFR)/tyrosine kinase/mitogen-activated protein kinase (MAPK)/inhibitor of κB kinase (IKK)β-mediated signaling pathway. In this work, we show that, similar to epidermal growth factor (EGF), 20-HETE (10 nM) activates EGFR by stimulating tyrosine phosphorylation; however, unlike 20-HETE, EGF does not induce ACE expression, and pretreatment with a neutralizing antibody …

Genesis And Growth Of Extracellular Vesicle-Derived Microcalcification In Atherosclerotic Plaques, Joshua D. Hutcheson, Claudia Goettsch, Sergio Bertazzo, Natalia Maldonado, Jessica L. Ruiz, Wilson Goh, Katsumi Yabusaki, Tyler Faits, Carlijn Bouten, Gregory Franck, Thibaut Quillard, Peter Libby, Masanori Aikawa, Sheldon Weinbaum, Elena Aikawa

Clinical evidence links arterial calcification and cardiovascular risk. Finite-element modelling of the stress distribution within atherosclerotic plaques has suggested that subcellular microcalcifications in the fibrous cap may promote material failure of the plaque, but that large calcifications can stabilize it. Yet the physicochemical mechanisms underlying such mineral formation and growth in atheromata remain unknown. Here, by using three-dimensional collagen hydrogels that mimic structural features of the atherosclerotic fibrous cap, and high-resolution microscopic and spectroscopic analyses of both the hydrogels and of calcified human plaques, we demonstrate that calcific mineral formation and maturation results from a series of events involving the …
