Eyes Wide Shopped: Shopping Situations Trigger Arousal in Impulsive Buyers
Underlying dataset for: Serfas, B. G., BĂĽttner, O. B., & Florack A. (2014) Eyes wide shopped: Shopping situations trigger arousal in impulsive buyers. PLoS ONE 9(12): e114593. doi:10.1371/journal.pone.0114593 --
The present study proposes arousal as an important mechanism driving buying impulsiveness. We examined the effect of buying impulsiveness on arousal in non-shopping and shopping contexts. In an eye-tracking experiment, we measured pupil dilation while participants viewed and rated pictures of shopping scenes and non-shopping scenes. The results demonstrated that buying impulsiveness is closely associated with arousal as response to viewing pictures of shopping scenes. This pertained for hedonic shopping situations as well as for utilitarian shopping situations. Importantly, the effect did not emerge for non-shopping scenes. Furthermore, we demonstrated that arousal of impulsive buyers is independent from cognitive evaluation of scenes in the pictures

Expression, Purification, Structural and Functional Analysis of SycB: A Type Three Secretion Chaperone From Yersinia Enterocolitica
In Yersinia enterocolitica biovar 1B, a genome
encoded TTSS designated as Ysa-Ysp system is used for
virulence. SycB is an annotated chaperone to this system.
SycB is soluble in presence of translocator YspC. SycB and
its truncated form (DSycB(1–114)) exist as dimers. YspC
forms a 1:1 complex with SycB. Homology model of SycB
shows a flexible N-terminal may be required for solubility
and dimerization; and concave core formed by antiparallel
helices of TPRs. Far UV CD spectra confirm that SycB is
predominantly alpha helical. Near UV CD spectra show that
SycB has tertiary structure at pH 7.2 (native folded protein),
which disappears at pH 5 (molten globule) and SycB
releases YspC at pH 5. SycB has a cooperative melting
behavior. At pH 7.2, SycB shows solvent accessible
hydrophobic patches. Concave core in the model exhibits
ANS binding within FRET distance of tyrosines in the TPR,
allowing a range of interaction of SycB with its ligand
