Mobile marketing provides an innovative channel for transmitting advertising messages to customers via mobile devices. The growth of mobile advertising in recent years requires that researchers and practitioners understand consumer perceptions of this form of advertising. The purpose of this paper is to investigate factors influencing the perception of mobile advertising in different cultures. Based on samples from Austria and Japan, we empirically examine relevant m-advertising effects. The results suggest that infotainment and credibility are key factors predicting advertising value among Austrians and the Japanese. However, our findings show that Japanese customers are more irritated by mobile advertising than are Austrian respondents.
Coronaviruses
(CoVs) cause numerous diseases, including Middle
East respiratory syndrome and severe acute respiratory syndrome, generating
significant health-related and economic consequences. CoVs encode
the nucleocapsid (N) protein, a major structural protein that plays
multiple roles in the virus replication cycle and forms a ribonucleoprotein
complex with the viral RNA through the N protein’s N-terminal
domain (N-NTD). Using human CoV-OC43 (HCoV-OC43) as a model for CoV,
we present the 3D structure of HCoV-OC43 N-NTD complexed with ribonucleoside
5′-monophosphates to identify a distinct ribonucleotide-binding
pocket. By targeting this pocket, we identified and developed a new
coronavirus N protein inhibitor, N-(6-oxo-5,6-dihydrophenanthridin-2-yl)(N,N-dimethylamino)acetamide hydrochloride
(PJ34), using virtual screening; this inhibitor reduced the N protein’s
RNA-binding affinity and hindered viral replication. We also determined
the crystal structure of the N-NTD–PJ34 complex. On the basis
of these findings, we propose guidelines for developing new N protein-based
antiviral agents that target CoVs.
This study compared the differences of two types of buckwheat sprouts, namely, common buckwheat ( Fagopyrum esculentum Moench) and tartary buckwheat ( Fagopyrum tataricum (L.) Gaertn.), in general composition, functional components, and antioxidant capacity. The ethanol extracts of tartary buckwheat sprouts (TBS) had higher reducing power, free radical scavenging activity, and superoxide anion scavenging activity than those of common buckwheat sprouts (CBS). As for chelating effects on ferrous ions, CBS had higher values than TBS. Rutin was the major flavonoid found in these two types of buckwheat sprouts, and TBS was 5 fold higher in rutin than CBS. The antioxidant effects of buckwheat sprouts on human hepatoma HepG2 cells revealed that both of TBS and CBS could decrease the production of intracellular peroxide and remove the intracellular superoxide anions in HepG2 cells, but TBS reduced the cellular oxidative stress more effectively than CBS, possibly because of its higher rutin (and quercetin) content.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
