A German Shepherd Dog was evaluated for clinical signs of multifocal, progressive brain disease. Despite supportive care, the dog died shortly after hospital admission. Granulomatous meningoencephalitis with intralesional fungal hyphae was diagnosed postmortem. The fungus was identified as Sporobolomyces roseus by polymerase chain reaction amplification and sequencing of the ITS2 region. 相似文献

In this study we investigated the influence of technical factors (positioning, background (BG) correction and attenuation correction) on qualitative and quantitative (absolute (AU) and relative (RU) uptake) assessment of feline kidneys with (99m)technetium labelled dimercaptosuccinic acid ((99m)Tc-DMSA). Eleven healthy adult cats were included. Influence of BG and depth correction on quantitative assessment was evaluated. Depth correction was based on the geometric mean method (using dorsal and ventral images) and the use of two standards placed over each individual kidney. Visual evaluation showed superiority of dorsal and ventral over lateral positioning due to increased separation of the kidneys permitting region of interest (ROI) placement without overlap. No apparent influence of BG correction was found for RU. However, AU was systematically overestimated without BG correction. Depth correction did not seem to affect RU in most cases, however, in some cats the differences were not negligible. The values for AU without depth correction were lower compared to depth corrected values. 相似文献

Comparison between organic and conventional kiwifruit cultivars 'Hayward' and 'Bidan', which was done by four radical scavenging assays, ESI-MS, and DSC measurements, showed significant differences between the cultivars. Such results were not estimated in kiwifruit growing under organic and conventional conditions. The extraction of bioactive compounds was done by two different methods: sequential extraction with ethyl acetate followed by methanol and maceration with methanol and ethyl acetate. The highest yield of polyphenols was found in the new cultivar 'Bidan' in comparison with the classic 'Hayward', by direct extraction with methanol. This is the first investigation of 'Bidan' kiwifruit cultivar, grown under organic conditions and compared with 'Hayward' organic. High contents of bioactive compounds and antioxidant and antiproliferative properties of the two kiwifruit cultivars justify their use as sources of valuable antioxidants. It is necessary to continue this study as a long-term experiment to eliminate the influence of seasonality. 相似文献

雄性不育性状被用在植物育种中,以降低种子生产成本。雄性不育分为细胞核雄性不育(GMS)和细胞质雄性不育(CMS)2种类型,在辣椒商业育种中都有应用。因为缺少恢复源,细胞质雄性不育系统在诸如甜椒等一些辣椒品种上并不适用。因此,细胞核雄性不育对于甜椒的种子生产而言就非常重要。本研究构建了一个F:分离群体,利用集群分离分析法(BSA)和扩增片段长度多态性(AFLP)技术获得了一个与甜椒细胞核雄性不育连锁的标记。我们分析了1024对AFLP引物,发现EcoRIACG/MseIGTF引物扩出了多态性。对多态性AFLP标记所扩增的395bp片段重新设计引物,进行高分辨率熔解曲线分析(HRM)。在92个Fz单株中,有87个单株的性状和HRM标记表型相一致。这个HRM标记被定位在AC99连锁图的第5号染色体上。 相似文献
