Clinical symptoms and histopathological changes in coho salmon affected by the erythrocytic inclusion body syndrome (EIBS) are caused by the infection of piscine orthoreovirus 2 (PRV-2).

The relationship of histopathological changes and the infection of Piscine orthoreovirus 2 (PRV-2) was investigated in coho salmon that were suffering from the erythrocytic inclusion body syndrome (EIBS). Immunohistochemical observations revealed abundant σ1 protein of PRV-2 in the spongy layer of the ventricle of the heart, where severe myocarditis was observed. In the spleen, the virus protein was detected in many erythrocytes, some of which were spherical-shaped and apparently dead.

Global Kinetoplastea phylogeny inferred from a large-scale multigene alignment including parasitic species for better understanding transitions from a free-living to a parasitic lifestyle.

All members of the order Trypanosomatida known to date are parasites that are most likely descendants of a free-living ancestor. Trypanosomatids are an excellent model to assess the transition from a free-living to a parasitic lifestyle, because a large amount of experimental data has been accumulated for well-studied members that are harmful to humans and livestock (Trypanosoma spp. and Leishmania spp.

Full-Genome Sequencing and Confirmation of the Causative Agent of Erythrocytic Inclusion Body Syndrome in Coho Salmon Identifies a New Type of Piscine Orthoreovirus.

Erythrocytic inclusion body syndrome (EIBS) causes mass mortality in farmed salmonid fish, including the coho salmon, Onchorhynchus kisutchi, and chinook salmon, O. tshawytscha. The causative agent of the disease is a virus with an icosahedral virion structure, but this virus has not been characterized at the molecular level.

Disinfection of fertilized eggs of the edible ascidian Halocynthia roretzi for prevention of soft tunic syndrome.

Azumiobodo hoyamushi, the causative agent of soft tunic syndrome, was likely introduced to farming sites of the edible ascidian Halocynthia roretzi via ascidian spat. The source of infection is thought to be cysts of A. hoyamushi that reside in the substrates on which the ascidian spat are attached, but not the spat themselves.

Encystment and excystment of kinetoplastid Azumiobodo hoyamushi, causal agent of soft tunic syndrome in ascidian aquaculture.

Soft tunic syndrome in the edible ascidian Halocynthia roretzi is caused by the kinetoplastid flagellate Azumiobodo hoyamushi, which was found to assume a fusiform cell form with 2 flagella in axenic, pure culture. When the flagellate form was incubated in sterilized artificial seawater (pH 8.4), some of the cells became cyst-like and adhered to the bottom of the culture plate.

Azumiobodo hoyamushi, the kinetoplastid causing soft tunic syndrome in ascidians, may invade through the siphon wall.

The infectious kinetoplastid Azumiobodo hoyamushi causes 'soft tunic syndrome', a serious problem in aquaculture of the edible ascidian Halocynthia roretzi. Infection tests using diseased tunics demonstrated that juvenile (0.8 yr old) individuals never developed soft tunic syndrome, but all individuals in the other age groups (1.

Detection of the kinetoplastid Azumiobodo hoyamushi, the causative agent of soft tunic syndrome, in wild ascidians Halocynthia roretzi.

The occurrence of soft tunic syndrome in wild populations of the ascidian Halocynthia roretzi was monitored by diving at 5 to 6 sites in Miyagi Prefecture in Japan in summer 2010 and 2011. These sites were located at varying distances from farming sites at which the disease had previously been detected. All dead ascidians were collected, and their tunics were examined for Azumiobodo hoyamushi, the causative agent of soft tunic syndrome, using 18S rRNA PCR.

A successful strategy for increasing the influenza vaccination rate of healthcare workers without a mandatory policy outside of the United States: a multifaceted intervention in a Japanese tertiary care center.

Objective: Although mandatory vaccination programs have been effective in improving the vaccination rate among healthcare workers, implementing this type of program can be challenging because of varied reasons for vaccine refusal. The purpose of our study is to measure improvement in the influenza vaccination rate from a multifaceted intervention at a Japanese tertiary care center where implementing a mandatory vaccination program is difficult.

Design: Before-and-after trial.

Peri-operative morbidity and mortality related to radical cystectomy: a multi-institutional retrospective study in Japan.

Unlabelled: What's known on the subject? and What does the study add? Radical cystectomy remains associated with comparatively high perioperative morbidity and mortality, despite improvements in surgical techniques and perioperative care. At present, most studies on the complications associated with open radical cystectomy were derived from Western academic high-volume centres, and data from Japan and other Asian countries were very limited. Using the modified Clavien grading system and 11 category grouping reported from MSKCC, we observed that 68% of patients experienced at least one complication within 90 days of surgery, and 17% of patients experienced major complications (90-day mortality rate = 2%), which were compatible with reports from Western high-volume centres.

Azumiobodo hoyamushi gen. nov. et sp. nov. (Euglenozoa, Kinetoplastea, Neobodonida): a pathogenic kinetoplastid causing the soft tunic syndrome in ascidian aquaculture.

We used morphological and genetic analyses to investigate a pathogenic kinetoplastid isolated from a diseased edible ascidian Halocynthia roretzi with soft tunic syndrome. The morphological characteristics of the kinetoplastid are similar to those in the order Neobodonida in the subclass Metakinetoplastida. However, the presence of unique globular bodies distinguishes this kinetoplastid from the other polykinetoplastic genera (i.

Soft tunic syndrome in the edible ascidian Halocynthia roretzi is caused by a kinetoplastid protist.

An etiological study was conducted to clarify whether the flagellate-like cells found in histological preparations of the tunic of diseased Halocynthia roretzi (Drasche) were the causative agent of soft tunic syndrome in this ascidian. When pieces of softened diseased tunic were incubated overnight in sterile seawater, live flagellated cells, which were actively swimming in the seawater, were observed in 47 out of 61 diseased ascidians (77%), but not in moribund or abnormal individuals with normal tunics (n = 36) nor in healthy animals (n = 19). The flagellate was morphologically very similar to those observed in histological sections of the diseased tunic.

Impact of diagnostic ureteroscopy on intravesical recurrence and survival in patients with urothelial carcinoma of the upper urinary tract.

Purpose: We determined whether diagnostic ureteroscopy for upper urinary tract cancer affects intravesical recurrence and cancer specific mortality.

Materials And Methods: In a retrospective, multi-institutional study we evaluated 208 patients undergoing nephroureterectomy for upper urinary tract cancer who had no perioperative systemic chemotherapy, history of invasive bladder cancer, distant metastasis or incomplete followup data. Of these 208 patients 55 who composed the study group underwent diagnostic ureteroscopy before nephroureterectomy while 153 serving as controls did not.

Pathological characteristics and clinical course of bladder tumour developing after nephroureterectomy.

Objectives: To determine the pathological features and clinical course of intravesical recurrence after nephroureterectomy (NU) for upper urinary tract (UUT) cancer.

Patients And Methods: Among 325 patients undergoing NU with bladder cuff excision for UUT cancer, in this retrospective multi-institutional study we evaluated 113 who developed bladder tumour after NU. Excluding patients with (i) perioperative systemic chemotherapy or radiotherapy for UUT cancer; (ii) a history of previous or synchronous bladder cancer at the time of NU; (iii) distant metastasis at the time of NU; (iv) a follow-up of <1 year after the initial bladder cancer recurrence; or (v) missing data, 74 patients were included in this study.

Multicenter phase II trial of combination therapy with meloxicam, a cox-2 inhibitor, and natural interferon-alpha for metastatic renal cell carcinoma.

Objective: We conducted a Phase II trial to investigate the efficacy of combined therapy with meloxicam, a cyclooxygenase-2 inhibitor and natural interferon (IFN)-alpha in renal cell carcinoma patients with distant metastasis.

Methods: The subjects of this study were patients with untreated renal cell carcinoma who were diagnosed from the results of imaging or pathological studies and who had measurable lesions according to the Response Evaluation Criteria in Solid Tumors (RECIST). Patients could be enrolled in the study irrespective of whether nephrectomy had been performed.

Objectives: To determine the role of lymph-node (LN) dissection in patients undergoing surgery for upper urinary tract (UUT) cancer.

Patients And Methods: We reviewed the clinicopathological data from 312 patients with UUT cancer treated predominantly by nephroureterectomy. The relationship between clinical characteristics and cancer-specific survival (CSS) was analysed, focusing on node-related information.

Chemical and electrochemical oxidation of thiophene-pyridine and thiophene-pyrimidine co-oligomers in solutions.

Chemical and electrochemical oxidation (or p-doping) of three types of pi-conjugated co-oligomers, Py-Th-(Th)n-Th-Py (Py = pyridine unit; Th = thiophene unit; 5a, n = 1; 6a, n = 2), Th-Py-(Th)n-Py-Th (5b: n = 1; 6b: n = 2), and Pym-Th-(Th)n-Th-Pym (Pym = pyrimidine unit; 5c: n = 1; 6c: n = 2), in solution systems has been studied. The chemical oxidation with NOBF(4) proceeded with isosbestic points in the UV-vis spectrum. The UV-vis absorption peak of 5a at 418 nm in CH(2)Cl(2) shifted to 456 nm after oxidation of 5a with NOBF(4).
