Levels of the selenium-containing imidazole compound selenoneine and overall organic selenium were measured in the muscle
of fishes by speciation analysis. The method involves monitoring 82Se levels by liquid chromatography inductively coupled plasma mass spectroscopy using a gel filtration column. Selenoneine
levels were found to be highest in swordfish muscle (concentration 2.8 nmol/g tissue). The selenoneine contents of bigeye
tuna, Pacific bluefin tuna, albacore, yellowfin tuna, and alfonsino muscle were 1.3–2.6 nmol/g tissue. In muscle of these
fishes, most organic selenium (9–42%) was present as selenoneine. In other fish species, such as Pacific sardine, greeneye,
skipjack, Pacific mackerel, horse mackerel, red sea bream, and Japanese barracuda, selenoneine levels were 0.1–1.4 nmol/g
tissue, accounting for 3–34% of organic selenium. In contrast, muscle of Japanese conger, Japanese anchovy, chum salmon, Pacific
saury, white croaker, and marbled sole contained levels of selenoneine below the level of detection (<0.05 nmol/g tissue).
Mercury and selenium contents were 0.01–5.12 nmol/g tissue and 1.4–19.1 nmol/g tissue. The Se-to-Hg molar ratio varied from
species to species, ranging from 1 for swordfish to 217 for marbled sole. 相似文献

We determined proton budgets of surface soils in a deciduous forest (Df) and a coniferous forest (Cf) of Volcanogenous Regosols in Tomakomai, Hokkaido of northern Japan. The total H+ source was 12.9 and 11.6 kmolc ha?1 y?1 at Df and Cf respectively, and the external H+ was 1% at Df and 2% at Cf. The primary H+ sources were vegetation uptake of base cations and nitrification, while the major H+ sinks were release of base cations and NO3 + uptake by vegetation. Leaching incubation experiments using A horizon soils including Df and Cf with NH4 + solutions (5.3, 15.9 mg N L?1) showed that H+ from nitrification was generally higher in the Df soil than Cf soil, and nitrification of Tomakomai Df soil was the highest in both treatments. Results of multiple regression analyses suggested that pHkCl and exchangeable Ca2+ contributed to the H+ generation via nitrification. Leaching experiments with dilute HCl (pH 3.3) revealed that cation release (mainly Ca2+) occurred, and the proportion of release by decrease of exchangeable cations was higher than that by mineral weathering. Mineral weathering in the Tomakomai soil was higher than the other soils. 相似文献

Few reports have investigated prognosis of canine gastrointestinal stromal tumor (GIST) cases treated by surgical resection alone. In the present study, we investigated the overall survival (OS) and prognostic factors for dogs with GIST treated by surgical complete resection alone. Fifty-three dogs were included, and the median OS was 18 months. Multivariate analysis showed that primary tumors in small intestine (P=0.04) is significantly associated with shorter OS, and median OS of the cases with cecum lesion and those with small intestine lesion was 22 and 6 months, respectively. The present study suggested primary tumor site was a novel prognostic factor for dogs with GIST treated by surgical complete resection alone. 相似文献

In the spring of 2007, seven raccoon dogs and a weasel were captured near the city of Tanabe in Wakayama prefecture, Japan. The causative agent of the animals' death 1-2 days after capture was identified as canine distemper virus (CDV) by virus isolation, immunostaining with an anti-CDV polyclonal antibody, and a commercially available CDV antigen-detection kit. Sequence analysis of hemagglutinin genes indicated the isolated viruses belong to genotype Asia-1 and possess the substitution from tyrosine (Y) to histidine (H) at position 549 that is associated with the spread of CDV to non-canine hosts. A serosurvey for CDV was then conducted among wild animals in the region. The animals assayed consisted of 104 raccoons, 41 wild boars, 19 raccoon dogs, five Sika deer, two badgers, one weasel, one marten, one Siberian weasel and one fox. Virus-neutralization (VN) tests showed that, except for fox and weasel, all of the species assayed had VN antibodies to CDV. Interestingly, 11 of the 41 wild boars (27%) and two of the five Sika deer assayed possessed VN antibodies to CDV. These findings indicate that CDV infection was widespread among wild mammals during this epizootic. 相似文献

The clinical usefulness of BCL6 gene expression was evaluated as a prognostic indicator in dogs with high-grade B-cell lymphoma. Forty-four dogs were diagnosed with centroblastic or B-cell immunoblastic type lymphoma according to the updated Kiel classification. BCL6 mRNA expression was measured by real-time PCR and its relationship with prognosis was analyzed. Progression-free and overall survival was not significantly different between the high BCL6 expression group (higher than the median) and the low BCL6 expression group (lower than the median) (P=0.99 and P=0.61, respectively). No correlation between BCL6 and prognosis was observed in this study, which is inconsistent with findings reported for human diffuse large B-cell lymphoma. BCL6 protein expression was not detected in the 11 dogs evaluated by immunohistochemistry. Furthermore, BCL6 protein expression was assessed in 13 archived paraffin-embedded high-grade canine lymphoma tissues and all were also negative. The results suggest that most canine high-grade B-cell lymphomas correspond to human diffuse large B-cell lymphoma with no immunohistochemical expression of BCL6. 相似文献

A 13-year-old spayed mixed-breed dog was diagnosed with a gastrointestinal
stromal tumor (GIST) after histopathological examination of an abdominal mass. Five months
after surgical resection of the tumor, we detected the recurrence of GIST with multiple
disseminated abdominal lesions. A sequence analysis of cDNA obtained from a biopsy of the
recurrent tumors revealed a mutation within exon 9 of the c-kit gene
(1523A>T, Asn508Ile), which has been shown to cause ligand-independent
phosphorylation of the KIT protein in GISTs and canine mast cell tumors (MCTs). Upon
detection of the recurrent tumors, we initiated treatment with imatinib mesylate (10
mg/kg, q 24 hr). After 2 months, the dog achieved complete remission. Our findings
indicate that canine GIST, and possibly MCT, may be responsive to molecular-targeted
therapy. 相似文献

Intradural disc herniation is a rarely reported cause of neurologic deficits in dogs and few published studies have described comparative imaging characteristics. The purpose of this retrospective cross sectional study was to describe clinical and imaging findings in a group of dogs with confirmed thoracolumbar intradural disc herniation. Included dogs were referred to one of four clinics, had acute mono/paraparesis or paraplegia, had low field magnetic resonance imaging (MRI) and/or computed tomographic myelography, and were diagnosed with thoracolumbar intradural disc herniation during surgery. Eight dogs met inclusion criteria. The prevalence of thoracolumbar intradural disc herniation amongst the total population of dogs that developed a thoracolumbar intervertebral disc herniation and that were treated with a surgical procedure was 0.5%. Five dogs were examined using low‐field MRI. Lesions that were suspected to be intervertebral disc herniations were observed; however, there were no specific findings indicating that the nucleus pulposus had penetrated into the subarachnoid space or into the spinal cord parenchyma. Thus, the dogs were misdiagnosed as having a conventional intervertebral disc herniation. An intradural extramedullary disc herniation (three cases) or intramedullary disc herniation (two cases) was confirmed during surgery. By using computed tomographic myelography (CTM) for the remaining three dogs, an intradural extramedullary mass surrounded by an accumulation of contrast medium was observed and confirmed during surgery. Findings from this small sample of eight dogs indicated that CTM may be more sensitive for diagnosing canine thoracolumbar intradural disc herniation than low‐field MRI. 相似文献
