Tissue-Specific Regulation Of Hnk-1 Biosynthesis By Bisecting Glcnac, Haruka Kawade, Jyoji Morise, Sushil K. Mishra, Shuta Tsujioka Sep 2021

Tissue-Specific Regulation Of Hnk-1 Biosynthesis By Bisecting Glcnac, Haruka Kawade, Jyoji Morise, Sushil K. Mishra, Shuta Tsujioka

Faculty and Student Publications

Human natural killer—1 (HNK-1) is a sulfated glyco-epitope regulating cell adhesion and synaptic functions. HNK-1 and its non-sulfated forms, which are specifically expressed in the brain and the kidney, respectively, are distinctly biosynthesized by two homologous glycosyltransferases: GlcAT-P in the brain and GlcAT-S in the kidney. However, it is largely unclear how the activity of these isozymes is regulated in vivo. We recently found that bisecting GlcNAc, a branching sugar in N-glycan, suppresses both GlcAT-P activity and HNK-1 expression in the brain. Here, we observed that the expression of non-sulfated HNK-1 in the kidney is unexpectedly unaltered in mutant mice …

Factors Affecting Customer Intention To Use Online Food Delivery Services Before And During The Covid-19 Pandemic, Chanmi Hong, Hayeon (Hailey) Choi, Eun Kyong (Cindy) Choi, Hyun Woo (David) Joung

Faculty and Student Publications

With the emerging popularity of online food delivery (OFD) services, this research examined predictors affecting customer intention to use OFD services amid the Coronavirus disease (COVID-19) pandemic. Specifically, Study 1 examined the moderating effect of the pandemic on the relationship between six predictors (perceived usefulness, perceived ease of use, price saving benefit, time saving benefit, food safety risk perception, and trust) and OFD usage intention, and Study 2 extended the model by adding customer perceptions of COVID-19 (perceived severity and vulnerability) during the pandemic. Study 1 showed that all of the predictors except food safety risk perception significantly affected OFD …


Implication Of Stigmatization On Investors Financial Risk Tolerance: The Case Of Gay Men, Francisca M. Beer, Joseph D. Wellman Sep 2021

Implication Of Stigmatization On Investors Financial Risk Tolerance: The Case Of Gay Men, Francisca M. Beer, Joseph D. Wellman

Faculty and Student Publications

This study evaluates whether the salience of discrimination and perceived stigmatization influence gay men's financial risk tolerance (FRT). This evaluation is conducted using the FRT measure of Grable and Lytton (1999), a “two-study ruse” approach and a hierarchical linear regression model. The findings show that individuals with anticipated stigmatization, after being exposed to information about bias against their community, exhibited greater FRT. These results support the hypothesis that risk-taking behavior by members of stigmatized populations increases when they experience discrimination.

Study Of Forward And Backward Modes In Double-Sided Dielectric-Filled Corrugated Waveguides, Pilar Castillo-Tapia, Francisco Mesa, Alexander Yakovlev, Guido Valerio, Oscar Quevedo-Teruel Sep 2021

Study Of Forward And Backward Modes In Double-Sided Dielectric-Filled Corrugated Waveguides, Pilar Castillo-Tapia, Francisco Mesa, Alexander Yakovlev, Guido Valerio, Oscar Quevedo-Teruel

Faculty and Student Publications

This work studies the propagation characteristics of a rectangular waveguide with aligned/ misaligned double-sided dielectric-filled metallic corrugations. Two modes are found to propagate in the proposed double-sided configuration below the hollow-waveguide cutoff frequency: a quasi-resonant mode and a backward mode. This is in contrast to the single-sided configuration, which only allows for backward propagation. Moreover, the double-sided configuration can be of interest for waveguide miniaturization on account of the broader band of its backward mode. The width of the stopband between the quasi-resonant and backward modes can be controlled by the misalignment of the top and bottom corrugations, being null …

Caption This: Creating Efficiency In Audiovisual Accessibility Using Automatic Speech Recognition Toolkit, Abigail Norris-Davidson, Michelle Emanuel

Library Publications

In the last several years, there has been a growing awareness of the need for digital accessibility in cultural heritage institutions. While initiatives to make content accessible and equitable for all patrons are vital for the continued growth and effectiveness of these institutions, they are not changes that can be made overnight. Remediating content requires time, knowledge, and effective tools. For many solo or siloed cultural heritage institutions, it can be difficult to commit the resources necessary for remediation. Nevertheless, these institutions will need to dedicate significant amounts of time to increasing accessibility in their digital collections, including audiovisual (A/V) …

The challenges faced with current fluorescence imaging agents have motivated us to study two nanostructures based on a hydrophobic dye, 6H-pyrrolo[3,2-b:4,5-b’]bis [1,4]benzothiazine (TRPZ). TRPZ is a heteroacene with a rigid, pi-conjugated structure, multiple reactive sites, and unique spectroscopic properties. Here we coupled TRPZ to a tert-butyl carbamate (BOC) protected 2,2-bis(hydroxymethyl)propanoic acid (bisMPA) dendron via azide-alkyne Huisgen cycloaddition. Deprotection of the protected amine groups on the dendron afforded a cationic terminated amphiphile, TRPZ-bisMPA. TRPZ-bisMPA was nanoprecipitated into water to obtain nanoparticles (NPs) with a hydrodynamic radius that was comparison, TRPZ-PG was encapsulated in pluronic-F127 (Mw = 12 kD), a polymer surfactant …

Migration, Marginalization, And Institutional Injustice In The Rural South, Jin Young Choi Aug 2021

Migration, Marginalization, And Institutional Injustice In The Rural South, Jin Young Choi

Journal of Rural Social Sciences

At the new beginning of the next 50 years of the Southern Rural Sociological Association (SRSA), the SRSA Presidential Address calls for attention to the issues that rural immigrants have faced – the everyday experiences of international migrants, their marginalization, and institutional injustice in rural America, particularly in the rural South. These issues have often been ignored or downplayed in the larger dialogue on rural issues and in the public debates about immigration policy, even though these social problems have been a perennial issue. Rural social scientists are challenged to be organic intellectuals who do not hide in the ivory …


The Degree Of Polymerization And Sulfation Patterns In Heparan Sulfate Are Critical Determinants Of Cytomegalovirus Entry Into Host Cells, Dipanwita Mitra, Mohammad H. Hasan, John T. Bates, Michael A. Bierdeman Aug 2021

The Degree Of Polymerization And Sulfation Patterns In Heparan Sulfate Are Critical Determinants Of Cytomegalovirus Entry Into Host Cells, Dipanwita Mitra, Mohammad H. Hasan, John T. Bates, Michael A. Bierdeman

Faculty and Student Publications

Several enveloped viruses, including herpesviruses attach to host cells by initially interacting with cell surface heparan sulfate (HS) proteoglycans followed by specific coreceptor engagement which culminates in virus-host membrane fusion and virus entry. Interfering with HS-herpesvirus interactions has long been known to result in significant reduction in virus infectivity indicating that HS play important roles in initiating virus entry. In this study, we provide a series of evidence to prove that specific sulfations as well as the degree of polymerization (dp) of HS govern human cytomegalovirus (CMV) binding and infection. First, purified CMV extracellular virions preferentially bind to sulfated longer …

The potential neuroprotective capacity of four different sulfated glycans: Botryocladia occidentalis-derived sulfated galactan (BoSG) (MW > 100 kDa), Lytechinus variegatus-derived sulfated fucan (LvSF) (MW~90 kDa), high-molecular weight dextran sulfate (DxS) (MW 100 kDa), and unfractionated heparin (UFH) (MW~15 kDa), was assessed in response to the HIV-1 proteins, R5-tropic glycoprotein 120 (gp120) and/or trans-activator of transcription (Tat), using primary murine neurons co-cultured with mixed glia. Compared to control-treated cells in which HIV-1 proteins alone or combined were neurotoxic, BoSG was, among the four tested sulfated glycans, the only one capable of showing significant concentration-dependent neuroprotection against Tat and/or gp120, alone or combined. …

Public evaluations of the economy are key for understanding how citizens develop policy opinions and monitor government performance. But what drives economic evaluations? In this article, we argue the context in which information about the economy is distributed shapes economic perceptions. In high-quality information environments—where policies are transparent, the media is free, and political opposition is robust—mass perceptions closely track economic conditions. In contrast, compromised information environments provide openings for political manipulation, leading perceptions to deviate from business cycle fluctuations. We test our argument with unique data from eight Latin American countries. Results show restrictions on access to information distort …
