Comparison of Radiography and Computed Tomography for Evaluation of Third Carpal Bone Fractures in Horses.

Radiographs underestimate the extent of bone injury in horses with third carpal bone (C3) fractures (Fx). We aimed to describe bone pathologies identified using computed tomography (CT) and compare the diagnostic value of digital radiography (DR) and CT in horses with C3 Fx. CT images of 15 racehorses with C3 Fx and 10 controls were reviewed (Part 1) then DR and CT images of 26 racehorses (24 Thoroughbred, 2 Standardbred) with C3 Fx (Part 2) were evaluated.

Evaluation of locking compression plate fixation of the distal phalanx to the hoof wall as a potential therapy for laminitis.

Background: Surgical stabilisation of the distal phalanx (DP) is a potential therapeutic strategy for severe acute laminitis.

Objective: To evaluate the effects of locking compression plate (LCP) fixation of the DP to the dorsal hoof wall.

Study Design: Ex vivo and in vivo experiments.

A retrospective multicenter study on the use of locking compression plates for scapulohumeral arthrodesis in small equids.

Objective: To report on technical aspects and outcomes after scapulohumeral arthrodesis (SHA) with a locking compression plate (LCP) in small equids.

Study Design: Retrospective multicenter case series.

Animals: Client-owned Shetland Ponies, Miniature Shetlands, and American Miniature Horses (n = 15).

L-Aspartate as a high-quality nitrogen source in Escherichia coli: Regulation of L-aspartase by the nitrogen regulatory system and interaction of L-aspartase with GlnB.

Escherichia coli uses the C4-dicarboxylate transporter DcuA for L-aspartate/fumarate antiport, which results in the exploitation of L-aspartate for fumarate respiration under anaerobic conditions and for nitrogen assimilation under aerobic and anaerobic conditions. L-Aspartate represents a high-quality nitrogen source for assimilation. Nitrogen assimilation from L-aspartate required DcuA, and aspartase AspA to release ammonia.

Lamellar perfusion and energy metabolism in a preferential weight bearing model.

Background: Supporting limb laminitis (SLL) is suspected to be caused by lamellar ischaemia as a consequence of increased mechanical load.

Objectives: Examine the effects of prolonged preferential weight bearing (PWB) on lamellar perfusion and metabolism.

Study Design: In vivo experiment.
