Effect of a regular consumption of traditional and roasted oat and barley flakes on blood lipids and glucose metabolism-A randomized crossover trial.

Background: Regular consumption of the soluble dietary fiber β-glucan is associated with decreased total cholesterol (TC), low-density lipoprotein (LDL) cholesterol and blood glucose. Barley and oat flakes as natural sources of β-glucan were roasted to improve sensory quality. The aim of this study was to investigate whether roasting of barley and oat flakes changes the physiological impact of the β-glucan-rich flakes on glucose and lipid metabolism.

Testing the efficacy and comparability of ZooMS protocols on archaeological bone.

Collagen peptide mass fingerprinting, best known as Zooarchaeology by Mass Spectrometry (or ZooMS) when applied to archaeology, has become invaluable for the taxonomic identification of archaeological collagenous materials, in particular fragmentary and modified bone remains. Prior to MALDI-based spectrometric analysis, collagen needs to be extracted from the bone's inorganic matrix, isolated and purified. Several protocols are currently employed for ZooMS analysis, however their efficacy and comparability has not been directly tested.
