Juvenile temperate seabass Lateolabrax japonicus were sampled along the Yura River estuary from April to July 2008 to determine their distribution and feeding habits during
migration within a microtidal estuary. Throughout the sampling period, juvenile seabass were distributed not only in the surf
zone, but also in the freshwater zone, and they were particularly abundant in areas with aquatic vegetation in the freshwater
zone. This distribution pattern suggests that the early life history of the temperate seabass depends more intensively on
the river (freshwater) than previously considered. Small juveniles in the freshwater zone fed on copepods and chironomid larvae
and upon reaching a standard length (SL) of approximately 20 mm did they fed on mysids. In contrast, juveniles (approx. 17–80 mm
SL) in the surf zone fed mainly on mysids. 相似文献

Acetaminophen-induced liver injury in mice is a model system of human acetaminophen overdose and oxidative stress in vivo. The system is technically established, and we usually obtain severe liver damage in the treated mice; however, it is possible that the degree of liver damage is affected by the type of chow fed to mice. Thus, in this experiment, we investigated the effect of different chows on mice by comparing acetaminophen-induced liver damage, liver antioxidant level, and serum amino-acid concentrations. The results showed that differences in chows, even standard ones, affected mouse physiological conditions, with the response to oxidative stress greatly affected. 相似文献

Primary hepatic neuroendocrine tumors (PHNETs) are rare in dogs, and limited information exists about the treatment of these tumors. A 12-year-old castrated male French bulldog was presented to our clinic with gastrointestinal signs. Diagnostic tests revealed increased hepatic enzyme levels, a mass in the hepatic quadrate lobe, multiple intrahepatic nodules, and enlarged hepatic hilar lymph nodes. The liver mass was diagnosed cytologically as a malignant epithelial tumor suspected to be of neuroendocrine origin. The dog was treated with single-agent toceranib phosphate (TOC) and survived 25.1 months after the initial presentation. On necropsy, a liver mass was found and was subsequently diagnosed as a PHNET on histopathology. To the best of our knowledge, this is the first report of long-term survival in a dog with PHNET treated with TOC. 相似文献

Recently, based on the histological studies it is suggested that Pacific bluefin tuna (PBF) spawns in the Kuroshio–Oyashio transition, off the Pacific coast of northeastern Japan, in addition to the previously identified two spawning areas of the northwestern Pacific around the Nansei Islands and the Sea of Japan. Distributional surveys for PBF larvae have not been conducted in the Kuroshio–Oyashio transition, and thus, we conducted PBF larval surveys at twenty stations in this area in early August 2018 to obtain evidence for the spawning of PBF. Twelve PBF larvae (3.9–7.2 mm in body length) were collected at six stations where sea surface temperature ranged from 27.2 to 28.2°C. Otolith microstructure analysis indicated that age of these larvae ranged from 4 to 11 days after hatching and the larvae hatched in late July. Growth of the collected larvae was comparable to those in the other two spawning grounds. Therefore, PBF spawns, hatches, and at least survives to the postflexion stage, 11 days after hatching in the Kuroshio–Oyashio transition. This fact potentially has a large impact on recruitment processes of PBF if they survive to recruitment in this third spawning ground. 相似文献

ABSTRACT Soil organic phosphorus (P) is an important P source for biota especially in P-limited forests. Organic P has various chemical formations which differ in bioavailability and these organic P can be degraded by phosphatase enzymes. Here, we report soil P fractions inferred from solution 31P-NMR spectroscopy and soil phosphatase activities of two tropical rain forests on contrasting parent materials; sedimentary and ultramafic igneous (serpentinite) rocks. Compared to the sedimentary soils and previous studies, P fractions of the serpentinite soils have distinctly high proportions of pyrophosphate and scyllo-inositol hexakisphosphate (scyllo-IP6). The accumulation of pyrophosphate and scyllo-IP6 may be related to strong sorptive capacity of iron oxides present in the serpentinite soils, which implies a consequent low P availability in the serpentinite soils. Mean value of soil phosphatase activities was higher in the serpentinite soils than in the sedimentary soils, suggesting that biota in these serpentinite forests depend more on soil organic P as a P source. 相似文献

A survey of proliferative enteritis (PE) in pigs at a meat processing plant was conducted using polymerase chain reaction (PCR) testing methods. During the investigation period, 227 of 83,717 pigs brought to the meat processing plant from Iwate, Fukushima, Miyagi, Niigata, and Yamagata Prefectures displayed characteristic general pathological features in terminal ileum, including mucosal hypertrophy and reticulation of serosal surface. Of these, 179 cases were further examined in the laboratory. All cases displayed characteristic histopathological features, and the specific band of the Lawsonia intracellularis (Li) causative agent of PE in pigs was detected in 155 cases by PCR testing methods. These results suggested a general infiltration of Li in the Tohoku district. 相似文献

A survey was conducted to examine the distribution of Arcobacter species among livestock in Japan. During May 1999 and May 2000, fecal samples from cattle (n=332) and swine (n=250), chicken cloacal swabs (n=234), and vaginal swabs of cattle (n=61) and swine (n=15) were submitted for the isolation of Arcobacter species. Arcobacter species were isolated from 3.6 and 10.0% of the cattle and swine fecal samples, respectively, along with 14.5% of chicken cloacal swabs. No significant seasonal differences were observed. Species-specific polymerase chain reaction assay showed that A. butzleri was the most prevalent species (83.3, 60.0 and 47.1% of the cattle, swine and chicken isolates, respectively), followed by A. cryaerophilus 1B (16.7, 36.0 and 55.9% of the cattle, swine and chicken isolates, respectively). Of the samples from vaginal swabs, 8.1 and 13.3% were positive for Arcobacter in cattle and swine, respectively. This is the first report demonstrating the distribution of Arcobacter species among livestock in Japan. 相似文献
