Dear MARMAMs, My co-authors and I are happy to share our note on delphinid postmortem vitreous humor biochemistry, available online at: https://onlinelibrary.wiley.com/doi/epdf/10.1111/mms.13157.
Please let me know if you cannot access the document, as I am happy to share a .pdf with anyone interested. Zorotrian, T., Stern, A. W., Costidis, A., Harms, C. A., Gao, H., Fontaine, C., & Adams, H. R. (2024). Delphinid postmortem vitreous humor biochemistry as proxy for antemortem blood analyte concentrations. Marine Mammal Science, e13157. https://doi.org/10.1111/mms.13157 Biochemical analysis of vitreous humor has multiple forensic applications in human death investigations, including estimation of postmortem interval and as proxy for select antemortem serum/plasma analytes. Little work has been done on vitreous humor biochemistry in cetaceans due in part to a paucity of appropriate cases and relatively high cost of analysis. To investigate the utility of vitreous humor biochemistry in stranded delphinids, paired antemortem serum/plasma and postmortem vitreous humor samples (n=10) were analyzed on the UF Clinical Pathology Lab’s Beckman Coulter AU480. Results were assessed via a Wilcoxon signed-rank test and calculation of the intraclass correlation coefficient. This study supports the utility of postmortem biochemical analysis of delphinid VH for data on antemortem health status and metabolic state. Analytes that are likely to be informative for forensic purposes or to provide insight into antemortem health include UN, CREA, GLU, K, Na, and Cl. Sincerely, Tiffany Tiffany J.
