A residual fumigant effect is demonstrated for fruit held 1 to 3 days within its cardboard carton after fumigation with 1,2-dibromoethane (EDB). This residual fumigant effect reduces significantly the dosage required for a specified level of control when compared with that required for fruit removed from the carton immediately after airing when fumigation is completed. The effect is due to the slow release of gas sorbed during fumigation and to the slow dispersion of this gas from the carton.  相似文献

Because the central nervous system (CNS) is encased almost entirely in bone, the means by which the clinician can evaluate it are limited. Additionally, the small size of many exotic companion animals further complicates diagnostic evaluation of the brain and spinal cord. Knowledge of the advantages and limitations of different imaging modalities, along with the neuroanatomical localization and assessment of likely causes of disease, will permit the clinician to choose the most appropriate imaging method for the patient. This article discusses the basic imaging principles of radiology, myelography, CT, and MRI of the nervous system of companion exotic animals to aid exotic animal clinicians in selecting imaging modalities and interpreting the results.  相似文献

The polysaccharide content of wine is generally assumed to originate from grapes and yeasts, independent of bacterial metabolism, except for the action of certain spoilage species. This study shows that malolactic fermentation (MLF) significantly modifies the soluble polysaccharide (SP) concentration of various red Bordeaux wines. Wines with the highest initial SP concentration go on to present decreased SP concentration, whereas those with the lowest initial SP concentration rather go on to have a higher SP concentration after MLF. These tendencies were observed whatever the Oenococcus oeni strain (indigenous or starter) used for MLF. Neutral and charged SPs were affected, but to a degree that depended on the microorganisms driving the MLF. The SP modifications were directly linked to bacterial development, because non MLF controls did not present any significant change of SP concentration.  相似文献

The impact of the mutation causing dynamin 1 (DNM1)-associated exercise-induced collapse (d-EIC) was determined in a retrospective genetic survey. The frequency of DNM1 mutant allele carriers in Labrador retrievers from conformation show, field trial/hunt test, pet or service lines ranged from 17.9% to 38.0% and the frequency of homozygous mutant (EE genotype) individuals ranged from 1.8% to 13.6%; 83.6% of these EE Labradors were reported to have collapsed by 4 years of age. DNM1 mutation carriers and EE dogs with a collapse phenotype were also detected in Chesapeake Bay retrievers, Curly-coated retrievers, Boykin spaniels, Pembroke Welsh corgis and mixed breed dogs thought to be Labrador retriever crosses. The DNM1 mutation was not identified in Golden, Flat-coated, or Nova Scotia duck tolling retrievers, or 15 other non-retrieving breeds. Veterinarians and breeders should be aware that the DNM1 EE genotype is not completely penetrant and that d-EIC is a widespread health concern in several very popular breeds, as well as breeds whose genetic similarity to retrievers is not obvious.  相似文献

Fruit packed in fibreboard cartons required a higher dosage of 1,2-dibromoethane (EBD) for an effective commodity treatment than fruit packed in polystyrene trays. This was due to considerably greater sorption of EDB by fibreboard compared with polystyrene, as indicated by concentration-time products. However, compensating factors in the form of a lower sorption of EDB by the fruit itself when in fibreboard cartons, and a residual fumigant effect for fruit in such cartons, reduced the expected increase in dosage requirement. The required dosages of EDB for effective treatments were 20 g m?3 in fibreboard cartons and 16 g m?3 in polystyrene trays, for 2 h at 20°C.  相似文献

Globalization has created an entirely new landscape for veterinarians. Opportunities abound to meet the formidable challenges presented as animals, people, and microbes travel at a previously unimagined speed, fueled by the engine of commerce, resulting in a plethora of new diseases, issues, and partnerships. Re-tooling our profession to ensure that we can continue to fulfill our veterinary oath in the face of these changes will require both short- and long-term changes. It is essential that a single overarching, non-affiliated organization be formed to tie together all entities, providing the structure to create needed synergy to enhance our currently fragmented professional responses and to solicit funds to effect necessary changes.  相似文献
