Tenogenic induction of equine mesenchymal stem cells by means of growth factors and low-level laser technology. Tendons regenerate poorly due to a dense extracellular matrix and low cellularity. Cellular therapies aim to improve tendon repair using mesenchymal stem cells and tenocytes; however, a current limitation is the low proliferative potential of tenocytes in cases of severe trauma. The purpose of this study was to develop a method useful in veterinary medicine to improve the differentiation of Peripheral Blood equine mesenchymal stem cells (PB-MSCs) into tenocytes. PB-MSCs were used to study the effects of the addition of some growth factors (GFs) as TGFβ3 (transforming growth factor), EGF2 (Epi...

The objective of this study was to evaluate a triaxial accelerometer for objective measurement of PA in the horse by assessment of their practical utility and validity. Horses were recruited to establish both the optimal site of accelerometer attachment and questionnaire designed to explore owner acceptance. Validity and cut-off values were obtained by assessing PA at various gaits. Validation study...
How ultrasound technologies have expanded and revolutionized research in reproduction in large animals. Gray-scale ultrasonic imaging (UI) was introduced in 1980 and initially was used to examine clinically the reproductive tract of mares. By 1983 in mares and 1984 in heifers/cows, UI had become a tool for basic research. In each species, transrectal gray-scale UI has been used extensively to characterize follicle dynamics and investigate the gonadotropic control and hormonal role of the follicles. However, the use of transrectal UI has also disclosed and characterized many other aspects of reproduction in each species, including (1) endometrial echotexture as a biological indicator of circulati...

A DICOM viewer (ORS Visual) plug-in was developed with the ability to move and deform cuboidal volumetric CT datasets, and to produce images simulating the effects of tube-patient-detector distance and angulation. Computed tomographic datasets were acquired from two dogs, one cat, and one horse....
Reduced-size microchips for identification of horses: response to implantation and readability during a six-month period. In this study, readability of reduced-size microchips in horses and the response to implantation were analysed. It was hypothesised that small microchips can be implanted stress-free but are less readable than larger microchips. Adult mares (n=40) were implanted with a reduced-size microchip (10.9×1.6 mm) at the left side of the neck (size of conventional microchips 11.4×2.2 mm). Microchips were identified with three different scanners (A, B, C) immediately, and at 6, 12 and 28 weeks after implantation. Twelve out of the 40 mares were submitted to microchip implantation and control treatment...
Incorporating oral photography and endoscopy into the equine dental examination. This article discusses the significant features and use of digital cameras, intraoral cameras, and oral endoscopes in equine dental practice. Although system features believed to be important have been listed, specific system recommendations have been omitted, since each veterinarian must individually determine the best system to meet practice clinical needs and budget. Veterinarians are encouraged to thoroughly research not only the camera/endoscope purchase but also the capabilities of the entire system, the compatibility of the system with different computer software programs, the reputatio...
Advances in equine dental radiology. Although diagnostic images can be obtained with traditional rare-earth film-screen combinations, digital radiography (DR) has enhanced the ability of the general practitioner to obtain diagnostic radiographs of the equine head. With the widespread availability of DR in equine practices, the practitioner can more readily learn the correct positioning for the various projections of the equine head that are used to evaluate the dentition and sinuses. Digital systems provide rapid processing of the image, enabling the practitioner to correct positioning errors and retake the image without signific...
Horse-like walking, trotting, and galloping derived from kinematic Motion Primitives (kMPs) and their application to walk/trot transitions in a compliant quadruped robot. This manuscript proposes a method to directly transfer the features of horse walking, trotting, and galloping to a quadruped robot, with the aim of creating a much more natural (horse-like) locomotion profile. A principal component analysis on horse joint trajectories shows that walk, trot, and gallop can be described by a set of four kinematic Motion Primitives (kMPs). These kMPs are used to generate valid, stable gaits that are tested on a compliant quadruped robot. Tests on the effects of gait frequency scaling as follows: results indicate a speed optimal walking frequency around 3.4 Hz, an...
Use of a wireless, inertial sensor-based system to objectively evaluate flexion tests in the horse. A wireless, inertial sensor-based system has previously been validated for evaluation of equine lameness. However, threshold values have not been determined for the assessment of responses to flexion tests. The aim of this investigation was to evaluate a sensor-based system for objective assessment of the response to flexion. Methods: Healthy adult horses (n = 17) in work were recruited prospectively. Horses were instrumented with sensors on the head (accelerometer), pelvis (accelerometer) and right forelimb (gyroscope), before trotting in a straight line (minimum 25 strides) for 2 consecutive...
The basics of musculoskeletal magnetic resonance imaging: terminology, imaging sequences, image planes, and descriptions of basic pathologic change. The usefulness of magnetic resonance (MR) imaging in the diagnosis of equine lameness is unquestionable. As with most imaging modalities, advances in technology happen quickly, and the information that can be obtained can seem limitless. An understanding of MR sequences, expected signal intensity of normal tissues, and the role of multiplanar imaging is the foundation for interpreting MR images. The rapid development of new techniques and sequences and the potential for biochemical changes to be indirectly assessed using MR spectroscopy offer possibilities for the continued development of this...
