Circulating concentrations of biomarkers and metabolites related to vitamin status, one-carbon and the kynurenine pathways in US, Nordic, Asian, and Australian populations2017 •
Background: Circulating concentrations of biomarkers that are related to vitamin status vary by factors such as diet, fortification, and supplement use. Published biomarker concentrations have also been influenced by the variation across laboratories, which complicates a comparison of results from different studies.Objective: We robustly and comprehensively assessed differences in biomarkers that are related to vitamin status across geographic regions.Design: The trial was a cross-sectional study in which we investigated 38 biomarkers that are related to vitamin status and one-carbon and tryptophan metabolism in serum and plasma from 5314 healthy control subjects representing 20 cohorts recruited from the United States, Nordic countries, Asia, and Australia, participating in the Lung Cancer Cohort Consortium. All samples were analyzed in a centralized laboratory.Results: Circulating concentrations of riboflavin, pyridoxal 5'-phosphate, folate, vitamin B-12, all-trans retinol, 25...

The chemical analysis of an assemblage of glass artefacts and glassworking debris (including crucibles) has provided information on glass manufacturing technology at the beginning of the 17th century. The Glasshouse at Newent was one of the last to have been fuelled with wood. An examination of the chemical composition of the exterior surfaces of the crucibles confirms that they were heated in a wood-fuelled furnace. The glassworking debris indicates the production of a high-lime low-alkali (HLLA) glass of composition similar to that produced both in other forest regions (the Weald and Staffordshire) as well as in early coal-fired furnaces. The compositional similarities between HLLA glass produced in wood- and coal-fuelled furnaces suggest that both employed similar strategies to obtain fluxes for glassmaking. These results cast some doubt on the idea that ‘forest’ glassmakers used the ash from the wood fuel as a flux.
