Integrating ex situ biomimetic extraction analyses into contaminated sediment assessment and management decisions.
Integr Environ Assess Manag

This study evaluated a novel ex situ passive sampling biomimetic extraction (BE) method to estimate toxic potency in sediments. Gas chromatography with flame ionization detection (GC-FID) analysis of polydimethylsiloxane fibers equilibrated with field sediments was used to quantify bioavailable polyaromatic hydrocarbons (PAHs) and other unresolved, site-specific contaminant mixtures. This method is biomimetic because contaminants partition to the fiber based on hydrophobicity and abundance, and GC-FID quantification accounts for all constituents absorbed to the fiber that may contribute to toxicity.

Canadian children consume a significant proportion of daily foods at school, do not benefit from any federal school food program, and have historically inadequate diets. Assessment of dietary intakes at school can inform policy discussions for the design, funding, and delivery of school-based nutrition interventions. The objectives were to examine the most recent nationally representative dietary intake data of Canadian children at school by (i) location of food preparation, (ii) meal occasion, and (iii) as a proportion of total daily intakes.

Introduction: Heavy metal soil pollution is a global issue that can be efficiently tackled through the process of phytoremediation. The use of rapeseed in the phytoremediation of heavy metal-contaminated agricultural land shows great potential. Nevertheless, its ability to tolerate heavy metal stress at the molecular level remains unclear.

Department of Neurology, Tohoku University Graduate School of Medicine, Sendai, Japan.
Introduction: Mixed connective tissue disease (MCTD) patients often have myositis, however, myopathological and clinical data for MCTD are limited. Recent reports have shown that the pathology of MCTD myositis resembles that of immune-mediated necrotizing myopathy (IMNM), whereas earlier reports described perifascicular atrophy or inflammatory infiltrates predominantly in the perivascular region in MCTD myositis. We aim to describe the clinical and myopathological features of MCTD myositis.

In this sensor, SnO film has been deposited on the suspended core of HADCF by RF sputtering to produce loss mode resonance (LMR). The energy of the center core has been shown to be able to be coupled into the suspended core, taking advantage of the small distance involved and phase matching between two cores.
