JOURNAL OF EQUINE VETERINARY SCIENCE, 94.

By: T. Beachler n, C. Bailey n, H. Gracz n, D. Morgan n, K. Von Dollen n, K. Ellis n, J. Gadsby n , S. Lyle n

author keywords: Equine; Metabolomics; Allantoic; Amniotic; Nuclear magnetic resonance spectroscopy
MeSH headings : Allantois; Amniotic Fluid; Animals; Body Fluids; Female; Horses; Magnetic Resonance Spectroscopy; Pregnancy; Protons
TL;DR: The goal of this study was to characterize the global metabolomic profile of equine allantoic and amniotic fluid through nuclear magnetic resonance spectroscopy offetal fluids from 12 pregnancies through ultrasound-guided transabdominal puncture. (via Semantic Scholar)

2020 journal article

Plasma metabolomic profiling of healthy pregnant mares and mares with experimentally induced placentitis

Equine Veterinary Journal, 53(1), 85–93.

By: T. Beachler n, H. Gracz n, D. Morgan n, S. Bembenek Bailey  n, L. Borst n , K. Ellis n, K. Von Dollen n, S. Lyle n ...

author keywords: horse; placentitis; diagnosis; plasma; NMR spectroscopy; metabolomics
MeSH headings : Animals; Female; Horse Diseases; Horses; Metabolomics; Placenta Diseases / veterinary; Plasma; Pregnancy; Streptococcus equi
TL;DR: Two phases of metabolite changes were noted after experimental infection: An immediate rise in metabolite concentration involved in energy, nitrogen, hydrogen, and oxygen metabolism within 4 hours after inoculation that was followed by a decrease in metabolites involved inenergy and nitrogen metabolism at 4 days, coinciding with ultrasonographic diagnosis of placentitis.

Allantoic Metabolites, Progesterone, and Estradiol-17 beta Remain Unchanged After Infection in an Experimental Model of Equine Ascending Placentitis

JOURNAL OF EQUINE VETERINARY SCIENCE, 73, 95–105.

By: T. Beachler n, H. Gracz n, N. Long *, L. Borst n , D. Morgan n, A. Nebel n, N. Andrews n, J. Koipillai n ...

author keywords: Equine; Ascending placentitis; Metabolomics; Allantoic fluid
TL;DR: The results of this study established a database of equine allantoic fluid metabolites and confirmed the utility of uteroplacental ultrasound for detection of placentitis before the onset of hematologic changes. (via Semantic Scholar)

1999 journal article

129Xe NMR Investigation of the Free Volume in Dendritic and Cross-Linked Polymers

Macromolecules, 32(6), 1897–1903.

By: D. Morgan n, E. Stejskal n & A. Andrady* 

TL;DR: Xe NMR spectroscopy was used to study the free-volume changes associated with cross-linking of linear polymers and extensive chain branching in dendritic tree molecules and the change in chemical shift of the xenon was found to correlate well with the reciprocal of the average molecular weight between cross-links of the end-linked networks.
