Although foot pain may clearly be the cause when a horse with foot pathology does not tolerate farriery, it may be overlooked or underappreciated as the cause of this behavioral problem when the pathology is mild and/or chronic. In this study, the records of 11 adult horses whose behavior for farriery initially warranted sedation for trimming and shoeing were reviewed. All 11 horses had a history of chronic lameness that was mild to moderate, but foot pain was the presenting complaint in only seven horses - all with chronic laminitis. The other four horses had abnormal foot conformation (long-toe, low-heel, or “club foot), but the lameness had not been attributed to the foot. All 11 horses showed improvement in gait with corrective trimming and shoeing. In each case, sedation for farriery could be discontinued after one to six visits, concurrent with the improvements in gait and foot pathology. On the basis of the survey results from 17 professional farriers, an ethogram of farriery-related undesirable horse behavior was developed.  相似文献   

Evaluation of the learning curve for natural orifice transluminal endoscopic surgery: bilateral ovariectomy in dogs

Objective: Study the learning curve for canine Natural Orifice Transluminal Endoscopic Surgery (NOTES) ovariectomy by evaluating operative times and complications. Study Design: Preclinical research study. Animals: Adult female dogs (n=20). Methods: NOTES ovariectomy procedures were performed as follows: Feasibility Group 1 (n=5), Feasibility Group 2 (n=5), and Early Clinical Group 3 (n=10). Six steps of the procedure were identified, timed separately, and the overall time was recorded from introduction to removal of the endoscope. Complications were recorded. Repeated measures analysis of variance using ranked data compared the effect of group (3 levels) on the time for each step. Nonlinear regression using an exponential model with nonzero asymptote was used to model the operative time–procedure number relationship. Results: Overall median operative time was significantly longer for Group 1 (195 minutes; range, 160–265 minutes) than Group 2 (108 minutes; range, 81–148 minutes; P=.048) and Group 3 (77 minutes; range, 41–136 minutes; P=.0008). The estimated asymptotic operative time was 71 minutes (95% confidence interval, 41–100 minutes); this time was reached after 10 procedures. Gastric cleansing and removing the left ovary took significantly longer in Group 1 than in Group 2 or 3. Operative complications included incomplete ovarian excision, dropping an ovary during retrieval, and conversion to an open procedure. No intraoperative complications occurred in Group 3. Conclusion: NOTES procedures result in longer operative times in the early part of the learning curve and require considerable experience before reaching proficiency.  相似文献   

Molecular, ultrastructural, and biological characterization of Pennsylvania isolates of Plum pox virus

Plum pox virus (PPV) was identified in Pennsylvania in 1999. The outbreak was limited to a four-county region in southern Pennsylvania. Initial serological and molecular characterization indicated that the isolates in Pennsylvania belong to the D strain of PPV. The Pennsylvania isolates were characterized by sequence analysis, electron microscopy, host range, and vector transmission to determine how these isolates related to their previously studied European counterparts. Genetically, Pennsylvania (PPV-Penn) isolates were more closely related to each other than to any other PPV-D strains, and isolates from the United States, Canada, and Chile were more closely related to each other than to European isolates. The PPV-Penn isolates exist as two clades, suggesting the possibility of multiple introductions. Electron microscopy analysis of PPV-Penn isolates, including cytopathological studies, indicated that the virions were similar to other Potyvirus spp. PPV-Penn isolates had a herbaceous host range similar to that of European D isolates. There were distinct differences in the transmission efficiencies of the two PPV-Penn isolates using Myzus persicae and Aphis spiraecola as vectors; however, both PPV-Penn isolates were transmitted by M. persicae more efficiently than a European D isolate but less efficiently than a European M isolate.  相似文献

Robotic observations of dust storm enhancement of carbon biomass in the North Pacific     

Bishop JK  Davis RE  Sherman JT 《Science (New York, N.Y.)》2002,298(5594):817-821

Two autonomous robotic profiling floats deployed in the subarctic North Pacific on 10 April 2001 provided direct records of carbon biomass variability from surface to 1000 meters below surface at daily and diurnal time scales. Eight months of real-time data documented the marine biological response to natural events, including hydrographic changes, multiple storms, and the April 2001 dust event. High-frequency observations of upper ocean particulate organic carbon variability show a near doubling of biomass in the mixed layer over a 2-week period after the passage of a cloud of Gobi desert dust. The temporal evolution of particulate organic carbon enhancement and an increase in chlorophyll use efficiency after the dust storm suggest a biotic response to a natural iron fertilization by the dust.  相似文献

Evidence for ammonium-bearing minerals on ceres     

King TV  Clark RN  Calvin WM  Sherman DM  Brown RH 《Science (New York, N.Y.)》1992,255(5051):1551-1553

Spectra obtained from recent telescopic observation of 1-Ceres and laboratory measurements and theoretical calculations of three component mixtures of Ceres analog material suggest that an ammoniated phyllosilicate is present on the surface of the asteroid, rather than H(2)O frost as had been previously reported. The presence of an ammoniated phyllosilicate, most likely ammoniated saponite, on the surface of Ceres implies that secondary temperatures could not have exceeded 400 kelvin.  相似文献

PREDICTORS OF RESPONSE TO RADIOIODINE THERAPY IN HYPERTHYROID CATS     

Ruthanne  Chun  DVM  Laura D.  Garrett  DVM  Jan  Sargeant  DVM  PhD  Aprill  Sherman  DVM  James J.  Hoskinson  DVM 《Veterinary radiology & ultrasound》2002,43(6):587-591

The objective of this retrospective study was to evaluate hyperthyroid cats for pretreatment factors that would predict response to radioiodine therapy. Hyperthyroidism was diagnosed in 193 cats based on elevated serum thyroxine levels and/or elevated thyroid to salivary gland ratios on thyroid scintigraphy. All cats were treated with an intravenous bolus of 4 mCi of radioiodine and follow-up serum thyroxine levels were evaluated at 1 week and 1, 3, 6, and 12 months post-therapy. There was a significant relationship between pretreatment thyroxine values and post-treatment thyroxine values at all of the follow-up time points (p < 0.001). There was also a relationship between thyroid to salivary gland technetium scan ratio results and serum thyroxine values at pretreatment and at 1 week post-treatment (p = 0.02, 0.005, respectively). A greater scan ratio was associated with higher thyroxine levels at these time points, but not at 1, 3, 6 or 12 months post-therapy. Ninety-eight cats pretreated with methimazole were analyzed for the effect of this drug on response to therapy. Methimazole was discontinued > or = 5 days before radioiodine therapy in 58 cats and < 5 days in 31 cats, in 9 cats the number of days off methimazole was unknown. There was no difference in response to radioiodine based upon when methimazole was discontinued (p = 0.70).  相似文献
