AIM： To assess whether a 24-wk course of interferon （IFN） could prevent hepatocellular carcinoma （HCC） recurrence and worsening of liver function in patients with hepatitis C virus （HCV）-infected patients after receiving curative treatment for primary HCC.METHODS： Outcomes in 42 patients with HCV infection treated with IFN-α, after curative treatment for primary HCC （IFN group）, were compared with 42 matched curatively treated historical controls not given IFN （non- IFN group）.RESULTS： Although the rate of initial recurrence did not differ significantly between ]FN group and non-IFN group （0%, 44%, 61~, and 67% ys 4.8%, 53~, 81%, and 87% at 1, 3, 5, and 7 years, P = 0.153, respectively）, ]FN group showed a lower rate than the non-IFN group for second recurrence （0%, 10.4%, 28%, and 350/0 ys 0%, 30~ , 59%, and 66% at 1, 3, 5 and 7 years, P = 0.022, respectively）. Among the ]FN group, patients with sustained virologic response （SVR） were less likely to have a second HCC recurrence than ]FN patients without an SVR, or non-IFN patients. Multivariate analysis identified the lack of SVR as the only independent risk factor for a second recurrence, while SVR and Child-Pugh class A independently favored overall survival.CONCLUSION： Most intrahepatic recurrences of HCV-related HCC occurred during persistent viral infection. Eradication of HCV is essential for the prevention of HCC recurrence and improvement of survival.

Probability discounting is defined as the devaluation of outcomes as the probability of receiving or paying those decreases. A q-exponential probability discounting model based on Tsallis’ statistics has been proposed in econophysics (Takahashi, 2007, Physica A). We examined (a) fitness of the models to behavioral data of probability discounting of both gain and loss;and (b) relationships between parameters in the q-exponential probability discounting model across gain and loss. Our results demonstrated that, for both gain and loss, the q-exponential model better fits the behavioral data than exponential and hyperbolic functions, and there is the sign effect in q-exponential probability discounting. Relationships between Kahneman-Tversky’s prospect theory in behavioral economics and the q-exponential probability discounting are high-lightened.

This study proposes four possible energy supply chains from the megawatt class of photovoltaics (PV) installation in Kuala Lumpur, Kolkata, Beijing or Ulan Bator to end users in Tokyo Japan. In the proposed chains, the electricity generated from solar PV panels would be used to generate H2 through water electrolyzer. The H2 is then liquefied (or converted into organic hydride) and transported by tank truck for land as well as tanker for marine to Japan and finally supplied to fuel cells (FC) for power generation purpose. This study investigates the energy efficiencies of the proposed energy supply chain and the amount of CO2 emission in the transportation process from the four locations. As a result, it is found the largest amount of power could be generated in Ulan Batorthan in other cities with the same size of solar panel array, while it also emitted the largest amount of CO2 in the transportation process. The best energy efficiency is obtained in the case of Beijing. This study also revealed that the ratio of total energy consumption to calorific value of H2 after transportation in the case of H2 liquefaction is smaller than that in the case of organic hydride.

AIM: To assess the efficacy of low-dose intermittent interferon (IFN) therapy in patients with hepatitis C virus (HCV)-related compensated cirrhosis who had received curative treatment for primary hepatocellular carcinoma (HCC). METHODS: We performed a prospective case controlled study. Sixteen patients received 3 MIU of natural IFN- alpha intramuscularly 3 times weekly for at least 48 wk (IFN group). They were compared with 16 matched historical controls (non-IFN group). RESULTS: The cumulative rate of first recurrence of HCC was not significantly different between the IFN group and the non-IFN group (0% vs 6.7% and 68.6% vs 80% at 1- and 3-year, P = 0.157, respectively). The cumulative rate of second recurrence was not also significantly different between the IFN group and the non-IFN group (0% vs 6.7% and 35.9% vs 67% at 1- and 3-year, P = 0.056, respectively). Although the difference in the Child-Pugh classification score between the groups at initial treatment of HCC was not signifi cant, the score was signifi cantly worse at the time of data analysis in the non-IFN group than IFN group (7.19 ± 1.42 vs 5.81 ± 0.75, P = 0.0008). The cumulative rate of deviation from objects of any treatment for recurrentHCC was also higher in the non-IFN group than IFN group (6.7% and 27% vs 0 and 0% at 1- and 3-year, P = 0.048, respectively). CONCLUSION: Low-dose intermittent IFN-alpha therapy for patients with HCV-related compensated cirrhosis after curative HCC treatment was effective by making patients tolerant to medical or surgical treatment for recurrent HCC in the later period of observation.

Nasolabial cysts are uncommonly diagnosed non-odontogenic soft tissue lesions occurring close to the nasal alar region of the face. Patients usually present with a slowly enlarging asymptomatic swelling. Diagnosis is usually made in the early stages because of the esthetic effects. Histologically, the lesion is lined with non-keratinized squamous epithelium or, more frequently, pseudostratified columnar epithelium with goblet cells. These cysts are most often diagnosed in the fourth decade of life. However, we report a case of nasolabial cyst in an 80-year-old woman, and discuss the diagnosis, differential diagnosis, and treatment with reference to the literature.

To clarify the effect of exposure to methane fermentation on the survival of seeds of Rumexobtusifolius L. contained in dairy slurry, the percentage of seed germination was observed after the mesophilic （35 ℃） and thermophilic （55 ℃） methane fermentation. The number of survival seed was 0% at 55 ℃, 81.6% at 35 ℃ from methane fermentation, and 0% at 55℃, 75.5% at 35 ℃ after heat treatment. The survival rate of the seeds in methane fermentation was similar to heat treatment at 35 ℃. However, in the investigation of seed status, the number of primary and secondary dormant seeds was higher than after heat treatment. This result suggests that since Rumexobtusifolius L. seeds survive in dormant state in mesophilic methane fermentation, the usage of manure as fertilizer need to be considered.

Plasma control on high-β_N steady-state operation for JT-60 superconductingmodification is discussed. Accessibility to high-β_N exceeding the free-boundary limit isinvestigated with the stabilising wall of reduced-activated ferritic steel and the active feedbackcontrol of the ill-vessel non-axisymmetric field coils. Taking the merit of superconducting magnet,advanced plasma control for steady-state high performance operation could be expected.

In mathematical physics and psychology, “quantum decision theory” has been proposed to explain anomalies in human decision-making. One of such quantum models has been proposed to explain time inconsistency in human decision over time. In this study, we conducted a behavioral experiment to examine which quantum decision models best account for human intertemporal choice. We observed that a q-exponential model developed in Tsallis’ thermodynamics (based on Takahashi’s (2005) nonlinear time perception theory) best fit human behavioral data for both gain and loss, among other quantum decision models.
