Abnormal (Hydroxy)proline Deuterium Content Redefines Hydrogen Chemical Mass
Analyzing the δ2H values in individual amino acids of proteins extracted from vertebrates, we unexpectedly found in some samples, notably bone collagen from seals, more than twice as much deuterium in proline and hydroxyproline residues than in seawater. This corresponds to at least 4 times higher δ2H than in any...Gharibi, Hassan ; Chernobrovkin, Alexey L ; Eriksson, Gunilla ; Saei, Amir Ata ; Timmons, Zena …

Intraspecific macroscopic digestive anatomy of ring-tailed lemurs (Lemur catta), including a comparison of frozen and formalin-stored specimens
Digestive tract measurements are often considered species specific, but little information exists on the degree to which they change during ontogeny within a species. Additionally, access to anatomical material from nondomestic species is often limited, with fixed tissues possibly representing the only available source, though the degree to which this...Clauss, Marcus ; Trümpler, Jelscha ; Ackermans, Nicole L ; Kitchener, Andrew C ; Hantke, Georg …
