Clenbuterol is a b2-agonist bronchodilator and mucokinetic drug. When administered at the recommended dose of 0.8 mg/kg q 12 h, it reaches plasma levels that should relax airway smooth muscle. However, the measurable degree of bronchodilation achieved may not always be clinically obvious even in horses with heaves. After a ten-day treatment (0.8 mg/kg q 12 h), the half-life of elimination from ...

A nonlinear time domain seakeeping analysis has been performed for high-speed displacement hulls advancing in head seas with regular waves. An hybrid approach has been employed, solving the unsteady hydrodynamic problem in the frequency domain and the equations of motion in the time domain. A three dimensional Rankine panel method has been used in order to solve the hydrodynamic boundary value ...

The causative mutation for the black-and-tan (a (t) ) phenotype in dogs was previously shown to be a SINE insertion in the 5' region of Agouti Signaling Protein (ASIP). Dogs with the black-and-tan phenotype, as well as dogs with the saddle tan phenotype, genotype as a (t) /_ at this locus. We have identified a 16-bp duplication (g.1875_1890dupCCCCAGGTCAGAGTTT) in an intron of hnRNP associated w...

OBJECTIVE To investigate the possible influences of saddle type on the incidence of "lower back pain" in a cross section of equestrian riders. METHODS 108 equestrian riders completed a questionnaire concerning their riding habits and whether they suffered from lower back pain. In particular they were asked whether they used a traditional style/general purpose saddle (GP) or a deep seated/West...

We investigated changes in heart rate (HR) and HR variability as a function of age in newborn foals to old Thoroughbred horses. Experiments were performed on a total of 83 healthy and clinically normal Thoroughbred horses. Resting HR decreased with age from birth. The relationship between age and HR fit the equation Y=48.2X-0.129(R2=0.705); the relationship between age and HR for horses 0-7 yea...

OBJECTIVE To determine whether there was an association between a history of cribbing and epiploic foramen entrapment (EFE) of the small intestine in horses. DESIGN Retrospective study. ANIMALS 68 horses examined at the University of Illinois or the University of Liverpool veterinary teaching hospitals. PROCEDURE For horses examined at the University of Illinois that underwent surgery bec...

REASONS FOR PERFORMING STUDY Equine keratomycosis in the western USA has received little study, probably owing to its low prevalence. OBJECTIVES To determine clinical features, predominant fungal isolates, treatment modalities and outcomes of horses with keratomycosis in California and compare these with results from different geographic regions. METHODS Records of horses presented to the U...

background because of the economic importance of the arab race horses and also the role of toxoplasma gondii and neospora spp. in abortion and reproductive failure of these animals, we decided to perform this study. objectives we designed this study to investigate the seroprevalence of anti-toxoplasma gondii and anti-neospora spp. antibodies in arab horses from 12 cities of khuzestan province i...
