Fluispotter, a novel automated and wearable device for accurate volume serial dried blood spot sampling.

A novel automated serial dried blood spot (DBS) sampler, 'Fluispotter', was tested for its sampling performance. An LC-MS/MS method was developed for the analysis of cortisol in DBS samples serially spotted by Fluispotter. The cortisol concentrations in 148 paired DBS and plasma samples were compared across a hematocrit (HCT) range of 22-55%.

Dietary exposure to benzoxazinoids enhances bacteria-induced monokine responses by peripheral blood mononuclear cells.

Scope: To examine potentially immunomodulating effects of dietary benzoxazinoids (BXs), present in cereal grains.

Methods And Results: Nineteen healthy volunteers were randomly distributed into two groups, who received diets with high or low content of BXs for 3 wk. After a week's wash-out, the groups switched diets.
