High seroprevalence of Francisella tularensis with low titers in Oklahoma equids from 2021–2023 suggests widespread exposure in the state’s equine population

Evan Crisman, Martin O. Furr, Akhilesh Ramachandran

Objective: To determine the seroprevalence of Francisella tularensis in horses in Oklahoma and to describe factors associated with seropositivity. Methods: In this observational study, 238 frozen equine serum samples were tested for F tularensis by microagglutination assay (MAT). Samples were collected from …

Microvasculature of the suspensory ligament of the equine hind limb

Megan R. Williams, Evan Crisman, Brianne M. Taylor

OBJECTIVE: To describe the microvascular anatomy of the equine hind limb suspensory ligament. ANIMALS: 18 hind limbs harvested from 9 adult horses euthanized for reasons unrelated to lameness. METHODS: A catheter was placed in the transected cranial tibial artery at the level …

Nebulized glycosylated caffeic acid phenylether ester attenuation of environmental particulate-induced airway inflammation in horses

Jessica J. Rutledge, Jillian Paegelow, Jerry W. Ritchey, Anuradha Singh et autres

The objective of this study was to determine the extent that nebulized glycosylated caffeic acid phenylether ester-4-O-alpha-D-glucopyranoside (G-CAPE) attenuates particulate-induced airway inflammation in healthy horses. Our hypothesis was that nebulization with G-CAPE would result in improved respiratory scores, higher arterial oxygen partial …

Study of VO2 metal insulator transition (MIT) in thin films with femtosecond pulses and Raman spectroscopy

Elizabeth Radue, Evan Crisman, Lei Wang, S. Kittiwatanakul et autres

We study the dynamics of photo-induced MIT in VO2 films of different substrates with a pump-probe experiment at various temperatures, and also investigating the propagation of surface plasmons on VO2 in the metallic phase.

Substrate Effect on Optical Properties of Insulator-Metal Transition in VO2 Thin Films

Elizabeth Radue, Evan Crisman, Lei Wang, S. Kittiwatanakul et autres

In this paper we used Raman spectroscopy to investigate the optical properties of vanadium dioxide (VO2) thin films during the thermally induced insulating to metallic phase transition. We observed a significant difference in transition temperature in similar VO2 films grown on quartz …
