Glycerol permeability in two species of Peromyscus
… of rat and mouse to erythritol, mannitol, glycerol, and thiourea. Rat erythrocytes were more permeable to glycerol than to thiourea, whereas the reverse was true for mouse erythrocytes. Mouse erythrocytes also displayed a high degree of permeability to erythritol. However, this same …

The Reconstruction of Climate in Beringia by analysis of Glycerol Dialkyl Glycerol Tetraether (GDGT) Distributions using High Performance Liquid Chromatography – Mass Spectrometry (HPLC-MS).
… to mass spectrometric detection (HPLC-APCI-MS). Glycerol dialkyl glycerol tetraether (GDGT) ratios within the extracts were used to reconstruct sea surface temperatures (SSTs), mean air temperatures (MATs) and pH. Climatic and environmental parameters were successfully assessed and reconstructed …
