The detection of piroxicam, tenoxicam and their metabolites in equine urine by electrospray ionisation ion trap mass spectrometry.
Rapid communications in mass spectrometry : RCM    September 24, 2004   Volume 18, Issue 19 2338-2342 doi: 10.1002/rcm.1631
McKinney AR, Suann CJ, Stenhouse AM.An investigation has been conducted into the metabolism and urinary excretion of orally administered piroxicam and tenoxicam in the horse. The major component detected in urine after the administration of piroxicam was 5'-hydroxypiroxicam, which was detectable up to 24 h post-administration. Unchanged piroxicam was present only as a minor component. In contrast, unchanged tenoxicam was the major component observed after the administration of tenoxicam, being detectable for 72 h post-administration, while 5'-hydroxytenoxicam was a minor component. Phase II beta-glucuronide conjugation in each c...

Identification of reptilian and amphibian blood meals from mosquitoes in an eastern equine encephalomyelitis virus focus in central Alabama.
The American journal of tropical medicine and hygiene    September 24, 2004   Volume 71, Issue 3 272-276 
Cupp EW, Zhang D, Yue X, Cupp MS, Guyer C, Sprenger TR, Unnasch TR.Uranotaenia sapphirina, Culex erraticus, and Cx. peccator were collected in an enzootic eastern equine encephalomyelitis (EEE) virus focus in central Alabama (Tuskegee National Forest) from 2001 to 2003 and analyzed for virus as well as host selection. EEE virus was detected in each species every year except 2003, when pools of Cx. peccator were negative. Most (97%) of the 130 Cx. peccator blood meals identified were from ectothermic hosts; 3% were from birds. Among blood meals from reptiles (approximately 75% of the total), 81% were from Agkistrodon piscivorus (cottonmouth); all amphibian blo...
Genetic variation within and relationships among five subpopulations of Slovak Thoroughbred.
Acta veterinaria Hungarica    September 24, 2004   Volume 52, Issue 3 259-265 doi: 10.1556/AVet.52.2004.3.2
Sátková-Jakabová D, Trandzík J, Hudecová-Kvasnáková L, Hegedüsová-Zetochová E, Bugarský A, Buleca J, Zöldág L, Jakab F, Fl'ak P.Genetic variation at six microsatellite loci was analysed for five Thoroughbred subpopulations to determine the magnitude of genetic differentiation and the genetic relationships among the subpopulations. Significant deviations from Hardy-Weinberg equilibrium were shown for a number of locus-population combinations, with all subpopulations. The genetic diversities and relationships of five Thoroughbred subpopulations were evaluated using six microsatellites recommended by the International Society of Animal Genetics (ISAG). The allele frequencies, the effective numbers of alleles, and the obse...

Veterinary parasitology    September 24, 2004   Volume 124, Issue 3-4 249-258 doi: 10.1016/j.vetpar.2004.06.028
Döpfer D, Kerssens CM, Meijer YG, Boersema JH, Eysker M.Faeces of 484 horses were sampled twice with an interval of 6 weeks while anthelmintic therapy was halted. Faecal eggs counts revealed that 267 (55.2%) horses had consistently low numbers of eggs per gram faeces (EPG) (EPG 100). Horses with consistently high EPGs were more often mares with access to pasture, aged less than 6 or more than 23 years, that were dewormed at intervals longer than 6 months, and were treated for the last time more than 3 months before the start of the study. Horses with consistently low EPGs were more often male horses with no or limited access to pasture, that were ...
Development of a neutralizing monoclonal antibody-based blocking ELISA for detection of equine herpesvirus 1 antibodies.
Veterinary research communications    September 24, 2004   Volume 28, Issue 5 437-446 doi: 10.1023/b:verc.0000034996.18533.90
Singh BK, Ahuja S, Gulati BR.A single-dilution, sensitive and specific monoclonal antibody-based blocking enzyme-linked immunosorbent assay (B-ELISA) was developed as an alternative to the cumbersome virus neutralization test (VNT) for detection of equine herpesvirus-1 (EHV-1) antibodies. Neutralizing monoclonal antibodies (1H6 and 9C6) raised against EHV-1 (Hisar-90-7 strain) and sera from 70 horses (30 known negative and 40 known positive for EHV-1 antibodies by VNT) were used for standardization of the B-ELISA. Using a single serum dilution of 1:250 in B-ELISA, 100% specificity was obtained with both monoclonal antibod...

Identification of some new clemastine metabolites in dog, horse, and human urine with liquid chromatography/tandem mass spectrometry.
Rapid communications in mass spectrometry : RCM    September 24, 2004   Volume 18, Issue 19 2267-2272 doi: 10.1002/rcm.1622
Tevell A, Bondesson U, Törneke K, Hedeland M.The metabolism of clemastine was studied in dogs, horses, and humans after a single dose of Tavegyl. The urine collected was extracted by solid-phase extraction or hydrolyzed with beta-glucuronidase and then extracted by liquid-liquid extraction, prior to analysis for unchanged drug and phase I and II metabolites by liquid chromatography/tandem mass spectrometry. The metabolites were identified by their molecular mass and interpretation of the product ion spectra, since no standard substances were available. Unchanged drug was recovered in urine samples from dogs and humans, but not from horse...

Experience from Lipizzan horse and salmonid species endemic to the Adriatic river system. Examples for the application of molecular markers for preservation of biodiversity and management of animal genetic resources.
Journal of biotechnology    September 24, 2004   Volume 113, Issue 1-3 43-53 doi: 10.1016/j.jbiotec.2004.06.005
Dovc P, Susnik S, Snoj A.Management of breeding- and free-living populations, traditionally based on phenotypic traits, relays more and more on availability of reliable information about the basic population genetic parameters as heterozygosity, mean number of alleles per locus, percentage of polymorphic loci, population structuring, genetic distances and others. Therefore, the application of molecular markers, revealing a great deal of phenotypically hidden information, becomes inevitable for population analysis. Conservation geneticists use this information for implementation of appropriate management policies. Appl...
The serum proteome of Equus caballus.
Proteomics    September 21, 2004   Volume 4, Issue 10 3227-3234 doi: 10.1002/pmic.200400846
Miller I, Friedlein A, Tsangaris G, Maris A, Fountoulakis M, Gemeiner M.We constructed a reference two-dimensional protein map for horse (Equus caballus) serum. The serum proteins were separated by two-dimensional electrophoresis (2-DE); 29 different gene products were identified. Proteins represented by 25 spots/spot groups were identified by tandem nanoelectrospray mass spectrometry (MS), four by matrix-assisted laser desorption ionization time-of-flight (TOF) MS and one was sequenced by TOF-TOF technology. The identities of four proteins were deduced by similarity to the human plasma protein database. In selected cases, i.e. the immunoglobulins, immunoblotting ...
Inactivation of the cytotoxic activity of repin, a sesquiterpene lactone from Centaurea repens.
Chemical research in toxicology    September 21, 2004   Volume 17, Issue 9 1170-1176 doi: 10.1021/tx049864e
Tukov FF, Anand S, Gadepalli RS, Gunatilaka AA, Matthews JC, Rimoldi JM.Prolonged ingestion of Yellow Starthistle (Centaurea solstitialis) and Russian Knapweed (Centaurea repens) by horses has been shown to result in a fatal neurodegenerative disorder called equine nigropallidal encephalomalacia (ENE). Bioassay-guided fractionation of extracts from Centaurea species using the PC12 cell line have led to the identification of one of several putative agents, which may contribute to ENE, namely, the sesquiterpene lactone (SQL) repin (1), previously linked to ENE due to its abundance in C. repens. To characterize the molecular basis of repin-induced neurotoxicity, the ...
Topological assignment of the N-terminal extension of plasma gelsolin to the gelsolin surface.
The Biochemical journal    September 21, 2004   Volume 385, Issue Pt 3 659-665 doi: 10.1042/BJ20040875
Fock U, Jockusch BM, Schubert WD, Hinssen H.The actin-binding protein gelsolin is highly conserved in vertebrates and exists in two isoforms, a cytoplasmic and an extracellular variant, generated by alternative splicing. In mammals, these isoforms differ only by an N-terminal extension in plasma gelsolin, a short sequence of up to 25 amino acids. Cells and tissues may contain both variants, as plasma gelsolin is secreted by many cell types. The tertiary structure of equine plasma gelsolin has been elucidated, but without any information on the N-terminal extension. In this paper, we present topographical data on the N-terminal extension...

Skeletal atavism in a miniature horse. Tyson R, Graham JP, Colahan PT, Berry CR.An 8-month-old miniature horse filly was presented for evaluation of severe rotational and angular limb deformities of the thoracic and pelvic limbs. On radiographic examination, complete ulnas and fibulas were identified. These findings are consistent with a condition previously described as a form of atavism. The term atavism is used to describe the reappearance of a trait or character that was seen in all earlier evolutionary specimens of a particular species, but has not been seen in recent ancestors. The atavistic traits of complete ulnas and fibulas have previously been described in Wels...

Scintigraphic appearance of the dorsal cortex of the third metacarpus and third metatarsus in the horse. Schallberger SP, Doherr MG, Ueltschi G.The lack of "standard uptake pattern" to refer to when interpreting scintigraphic images poses a problem to anyone working with skeletal scintigraphy. An article written by Koblik et al. stated that in the normal scintigraphic image of older horses, the dorsal cortex of the metacarpus and metatarsus is not identifiable, whereas it can be identified in younger horses. In this retrospective study we evaluated the association between the age of a horse and visibility of the dorsal cortex of the metacarpus and metatarsus. We found that dorsal cortical uptake can be seen in the normal adult horse. ...
Ultrasound-guided atlanto-occipital puncture for myelography in the horse. Audigié F, Tapprest J, Didierlaurent D, Denoix JM.Complications of cervical myelography arising from the puncture of the subarachnoid space to collect the cerebrospinal fluid and to inject the contrast medium have been described in humans and animals. In this study, 2 ultrasound-guided procedures were developed for puncture of the atlanto-occipital subarachnoid space, collection of cerebrospinal fluid, and injection of contrast medium. Myelography was performed on 6 ataxic horses using these procedures. The first attempt to puncture the subarachnoid space was successful in 5 horses and in one horse, a second attempt was necessary. Collection ...
Structural investigation of pig metmyoglobin by 129Xe NMR spectroscopy.
Biochimica et biophysica acta    September 18, 2004   Volume 1674, Issue 2 182-192 doi: 10.1016/j.bbagen.2004.06.011
Corda M, Era B, Fais A, Casu M.The potentiality of xenon's sensitivity to its local magnetic environment is thoroughly investigated to probe internal structural differences between pig and horse metmyoglobin (MMb). These MMb's differ by 14 amino acids. One of these, Ile142 in horse MMb, is located in the proximal cavity, which is the xenon-binding site in horse MMb, and is replaced by Met142 in pig MMb. Specific and non-specific xenon-protein interactions are investigated here by 129Xe NMR chemical shifts and relaxation rate in aqueous solutions of pig MMb as a function of the xenon and protein concentrations. The results a...
Structure of long bones in mammals.
Journal of morphology    September 18, 2004   Volume 262, Issue 2 546-565 doi: 10.1002/jmor.10282
Locke M.Techniques for staining (silver, osmium, metal sulfides, ink) and microphotography (epi-illumination) of polished bone surfaces have been developed to visualize the three-dimensional structure of the shafts of mammalian long bones. Bone is a two-compartment system with capillaries and some kinds of connective tissue in one compartment separated from fibers of bone collagen, often forming lamellae, in the other. Laminar bone consists of stacks of lamellae separated by vascular spaces containing capillary network sheets. It is deposited at the periosteal and endosteal surfaces. Osteonic bone, we...

Confirmation and quantification of hemoglobin-based oxygen carriers in equine and human plasma by hyphenated liquid chromatography tandem mass spectrometry.
Analytical chemistry    September 18, 2004   Volume 76, Issue 17 5127-5135 doi: 10.1021/ac035430x
Guan F, Uboh CE, Soma LR, Luo Y, Jahr JS, Driessen B.Oxyglobin (OXY) and Hemopure (HMP) are produced from bovine hemoglobin (Hb) and were developed for the treatment of anemia in animal and human patients, respectively. Hemolink (HML) is a blood substitute of human Hb origin under development. The ability of these agents to carry oxygen in circulating blood and their promise to improve oxygen delivery to tissues supports the potential for their abuse in equine and human athletes. To deter athletes from abuse of these agents, a method has been developed for the detection, confirmation and quantification of OXY, HMP, and HML in equine and human pl...
Nuclear scintigraphic evaluation of the distal tarsal region in normal horses. Murray RC, Dyson SJ, Weekes JS, Branch MV, Hladick S.Bone-phase scintigraphy is sensitive to the dynamic process of bone modeling and remodeling, which may be adaptive or pathologic. Our knowledge of normal patterns of radiopharmaceutical uptake (RU) is limited, making interpretation of images problematic. It is therefore important to characterize normal patterns of RU at specific sites and relate these to age and exercise, to ensure valid interpretation of images in clinical cases with subtle lesions. This study aimed to characterize patterns of uptake of radiopharmaceutical in the distal tarsal region in clinically normal horses, and to invest...

Determination of peak vertical ground reaction force from duty factor in the horse (Equus caballus).
The Journal of experimental biology    September 17, 2004   Volume 207, Issue Pt 21 3639-3648 doi: 10.1242/jeb.01182
Witte TH, Knill K, Wilson AM.Measurement of peak vertical ground reaction force (GRFz) from multiple limbs simultaneously during high-speed, over-ground locomotion would enhance our understanding of the locomotor mechanics of cursorial animals. Here, we evaluate the accuracy of predicting peak GRFz from duty factor (the proportion of the stride for which the limb is in contact with the ground). Foot-mounted uniaxial accelerometers, combined with UHF FM telemetry, are shown to be practical and accurate for the field measurement of stride timing variables, including duty factor. Direct comparison with the force plate produc...
