Supplemental online resources improve data literacy education: Evidence from a social science methods course.

Despite the importance of data literacy skills for academic and professional careers, learning these skills is a source of stress and difficulty for undergraduate students. This study first introduces an online supplemental instruction resource to support student learning in an introductory data analysis course at a large public university. To evaluate its impact, we conduct a pre-registered double-blind within-subject experiment.

Effect of O-linked glycosylation on the antigenicity, cellular uptake and trafficking in dendritic cells of recombinant Ber e 1.

Ber e 1, a major Brazil nut allergen, has been successfully produced in the yeast Pichia pastoris expression system as homogenous recombinant Ber e 1 (rBer e 1) with similar physicochemical properties and identical immunoreactivity to its native counterpart, nBer e 1. However, O-linked glycans was detected on the P.pastoris-derived rBer e 1, which is not naturally present in nBer e 1, and may contribute to the allergic sensitisation.

Development of a protein microarray-based diagnostic chip mimicking the skin prick test for allergy diagnosis.

Protein microarrays have been successfully used for detection of allergen-specific IgE in patient sera. Here, we demonstrate proof-of-concept of a solid-phase technique coupling the high-throughput potential of protein microarrays with the biologically relevant readout provided by IgE reporter cells, creating a novel allergic sensitization detection system. Three proteins (κ-casein, timothy grass pollen extract, polyclonal anti-human IgE) were printed onto three different polymer-coated surfaces (aldehyde-, epoxy- and NHS ester-coated).
