An inexpensive, 3D‐printable breast muscle meter for field ornithologists

Journal of Field Ornithology, Volume 92, Issue 1, Page 67-76, March 2021., 2021
Abstract The size of the pectoral muscle is an important component of body condition in birds and has been linked to indices of fitness and migratory performance. Bauchinger et al. (2011. Journal of Ornithology 152: 507–514) developed, calibrated, and validated an aluminum “muscle meter” device that estimates the size of pectoral muscles noninvasively.

Symmetric dimethylarginine concentrations in dogs with International Renal Interest Society stage 4 chronic kidney disease undergoing intermittent hemodialysis

Journal of Veterinary Internal Medicine, Volume 33, Issue 6, Page 2635-2643, November/December 2019., 2019
Abstract Background Symmetric dimethylarginine (SDMA) is a methylated arginine derived from intranuclear methylation of l‐arginine by protein‐arginine methyltransferase and released into circulation after proteolysis. It is primarily eliminated by renal excretion, and its concentration is highly correlated with glomerular filtration rate (GFR) in ...
