Prenatal exposure to maternal cigarette smoking and DNA methylation: epigenome-wide association in a discovery sample of adolescents and replication in an independent cohort at birth through 17 years of age.

Lee K, et al.
The authors used the Infinium HumanMethylation450K BeadChip to search across 473,395 CpGs for differential DNA methylation associated with prenatal smoke exposure during adolescence in a discovery cohort and at birth, during childhood, and during adolescence in a replication cohort.
Their findings suggest that modifications of DNA methylation associated with prenatal maternal smoking may persist in exposed offspring for many years – at least until adolescence.
Comparative analysis of IgG responses to Plasmodium falciparum MSP1p19 and PF13-DBL1alpha1 using ELISA and a magnetic bead-based duplex assay (MagPix-Luminex) in a Senegalese meso-endemic community.

Perraut R, et al.
The authors investigated IgG response against the P. Falciparum merozoite surface protein-1 PfMSP1p19 and the PF13-DBL1alpha1 using an enzyme linked immunosorbant assay and a Luminex assay run on the MagPix platform. Archived plasma samples collected before the rainy season from 217 villagers living in Ndiop, a Senegalese meso-endemic setting, were studied. Based on their findings, they determined that multiplex assessment of antibody responses to a larger panel of antigens with the Luminex technology is warranted.
Same-single-cell analysis using the microfluidic biochip to reveal drug accumulation enhancement by an amphiphilic diblock copolymer drug formulation.

Khamenehfar A, et al.
A microfluidic biochip was used to select single multidrug-resistant cells, and the accumulation of daunoribicin was fluorescently measured in real time on the cells in the absence and presence of MePEG-b-PCL copolymer. The authors said the method allowed them to obtain drug accumulation information faster in comparison to conventional assays.
