The aims of this study were to determine the morphological patterns, physical examination characteristics and ultrasound findings of show jumping horses in training and to establish a score-based examination model for physical and ultrasound foBackground: Physical exercise is known to cause significant joint changes. Thus, monitoring joint behavior of athletic horses is essential in early disorders recognition, allowing the proper management. Objectives: The aims of this study were to determine the morphological patterns, physical examination characteristics and ultrasound findings of show jumping horses in training and to establish a score-based examination model for physical and ultrasound follow-ups of metacarpophalangeal joint changes in these animals. Methods: A total of 52 metacarpophalangeal joints from 26 horses who were initially in the taming stage were evaluated, and the horses’ athletic progression was monitored. The horses were evaluated by a physical examination and by B-mode and Doppler-mode ultrasound examinations, starting at time zero (T0), which occurred concomitantly with the beginning of training, and every 3 months thereafter for a follow-up period of 18 months. Results: The standardized examination model revealed an increase in the maximum joint flexion angles and higher scores on the physical and ultrasound examinations after scoring was performed by predefined assessment tools, especially between 3 and 6 months of evaluation, which was immediately after the horses started more intense training. The lameness score and the ultrasound examination score were slightly higher at the end of the study. Conclusions: The observed results were probably caused by the implementation of a traininBackground: Physical exercise is known to cause significant joint changes.

The lameness score and the ultrasound examination score were slightly higher at the end of the study. Conclusions: The observed results were probably caused by the implementation of a training regimen and joint adaptation to physical conditioning. The joints most likely undergo a pre-osteoarthritic period due to work overload, which can manifest in a consistent or adaptive manner, as observed during this study. Thus, continuous monitoring of young athlete horses by physical and ultrasound examinations that can be scored is essential. g regimen and joint adaptation to physical conditioning.

2-Mercaptopyrimidine (2MPy) forms a two-dimensional planar lattice on Au(111). This structure is able to intercalate guestmolecules such as the oligopyridines. To test the ability of the 2MPy lattice as a host able to intercalate a variety of moleculesregardless of their geometry and electronic structures, some arenes and polyenes were analyzed as possible guests. Benzene,naphthalene, azulene, phenanthrene, anthracene, biphenyl, uorobenzene and durene were selected to coadsorb with 2MPy on thesurfaces. The experimental data show that the arenes and polyenes selected coadsorb with 2MPy on Au(11) under dened ex-perimental conditions, forming a mixed layer with stoichiometry of 2:1 in thiol:guest. The STM contrast observed for the guestmolecules is compared to the experimental and theoretical results already published.. 2002 Elsevier Science B.V. All rights re-served.
