Fixation of a complete scapular neck fracture in a foal using two 3.5 mm locking compression plates 下载免费PDF全文
This report describes the successful surgical repair of a transverse, displaced scapula fracture in a foal. A 3.5 mm locking compression plate (LCP) was used on either side of the spine of the scapula. The suprascapular nerve was apparent upon dissection as it passed directly over the fracture line and care was taken to leave it intact, although the fracture line itself caused some irritation. The foal recovered without long‐term nerve damage and is sound at 1.5 years post surgery. 相似文献

Background
Hyperaccumulation, the rare capacity of certain plant species to accumulate toxic trace elements to levels several orders of magnitude higher than other species growing on the same site, is thought to be an elemental defense mechanism against herbivores and pathogens. Previous research has shown that selenium (Se) hyperaccumulation protects plants from a variety of herbivores and pathogens. Selenium hyperaccumulating plants sequester Se in discrete locations in the leaf periphery, making them potentially more susceptible to some herbivore feeding modes than others. In this study we investigate the protective function of Se in the Se hyperaccumulators Stanleya pinnata and Astragalus bisulcatus against two cell disrupting herbivores, the western flower thrips (Frankliniella occidentalis) and the two-spotted spider mite (Tetranychus urticae). 相似文献43.
Abstract Fungicide spray trials showed that high volume applications (1121 lha) of mancozeb, captafol and vondozeb reduced foliage and stem disease and substantially increased marketable yields of rain-fed tomatoes in northern Nigeria. The results suggest that captafol had a more persistent fungicidal action as there was no yield difference between the 7 and 14 day frequencies of application. U.I.v. methods (<12 l/ha) using three fungicides were compared with high volume treatments. The u.I.v. captafol treatment was particularly effective. An assessment was made of droplet distribution in relation to atomiser disc rotation speed and the height of carriage of the sprayer. 相似文献

Canine visceral leishmaniasis (CVL) is caused by Leishmania donovani complex parasites including L. donovani, Leishmania infantum and Leishmania chagasi. As some studies suggest that L. chagasi and L. infantum may be very similar or even the same species, the aim of the present study was to evaluate a commercial rapid ELISA test, originally designed for L. infantum, in the diagnosis of CVL in dogs naturally infected by L. chagasi. A total of 400 serum canine samples, including 283 positive dogs for CVL from an endemic area, 86 clinically healthy dogs from a non-endemic area and 31 dogs seropositive for confounding infectious agents (Trypanosoma cruzi, Toxoplasma gondii, Neospora caninum, Babesia canis and Ehrlichia canis) were used for test validation. An overall sensitivity of 94.7% (95% CI=91.41-97.01%) and specificity of 90.6% (95% CI=83.80-95.21%) was found, with a high degree of agreement (k=0.8445) to the indirect ELISA. When confounding infectious diseases were excluded, specificity increased to 100% (95% CI=95.8-100%), with a higher degree of agreement (k=0.8928). In conclusion, the commercial kit designed for L. infantum was a highly sensitive and specific device for detection of L. chagasi infection in dogs, which indicates high immunoreactivity similarities between L. infantum and L. chagasi. 相似文献

Summary Two distinct round patches were observed in a potato field where the haulm showed symptoms like those of blackleg. The remainder
of the field was in vigorous growth. Affected stems had long cracks andErwinia carotovora var.atroseptica was isolated from some. This had probably developed subsequently on damaged tissue and no rotting was apparent below soil
level. Most of the tubers were decayed but noErwinia and only green pseudomonads were detected. Local meteorological records showed that thunderstorms occurred on only one day
(1 August) in the six weeks before observation of the field symptoms. It was concluded from all evidence that the condition
described was caused by a lightning strike on that day. 相似文献

Clones of several diploid species capable of generating diplandroids (2n pollen) were identified by screening for the occurrence of 2n pollen. Diplandroid production was detected inSolatium bukasovi, S. canasense,S. cardiophyllum, S. chacoense, S. leptostigma, S. megistacrolobum, S. tarijense, S. tuberosum Group Phureja and Group Stenotomum. Parallel spindles at Ana II was the mechanism producing 2n pollen inS. chacoense, Group Phureja, and Group Stenotomum. The widespread distribution both taxonomically and geographically suggests a possible role for diplandroids in evolution. It also encourages exploration of a proposed breeding method in which tetraploids are generated from 2x × 2x matings. 相似文献
