The indirect photocatalytic reduction of arsenate to arsenite in aqueous solution with titanium dioxide(TiO_2)was investigated with various hole scavengers such as methanol, ethanol, 2-propanol, formaldehyde, acetone,formic acid and acetic acid. Although the direct photocatalytic reduction of arsenate to arsenite with TiO_2 was impossible, an indirect reduction of As(V) was possible in the presence of sacrificial electron donors to form strongly reductive radicals. The addition of ethanol was very effective for indirect photocatalytic reduction of As(V) in aqueous solution with TiO_2 photocatalyst. The indirect photocatalytic reduction rate of As(V) may be related with both the reaction rate constants of reaction of hydroxyl radicals with hole scavenger and the reactivities for the radicals M· which are produced by the reaction of ·OH with hole scavenger.

A sensitive and selective preconcentration method using solid-phase extraction （SPE） disk made from oxidized multiwalled carbon nanotubes （OMWCNTs）, has been developed for the determination of aniline derivatives, such as 2-nitroaniline （2-NA）, 4- nitroaniline （4-NA）, and 2,4-dichloroaniline （2,4-DCA） in water samples. Anilines were extracted onto OMWCNT disk and then determined by high performance liquid chromatography （HPLC） with UV detector. Several parameters on the recovery of the analytes were investigated. The experimental results showed that it was possible to obtain quantitative analysis when the solution pH was 8 using 200 mL of validation solution containing 2 ug of anilines and 10 mL of acetonitrile/ethanol （8/2, v/v） as an eluent. Relative standard deviations for five determinations were 7.5% （2-NA）, 6.5% （4-NA） and 3.8% （2,4-DCA） under optimum conditions. The linear range of calibration curves were 0.5 *** 1 to 15 ***-1 for each analyte with good correlation coefficients. The detection limits （3S/N） of 2-NA, 4-NA and 31 *** -1 and 26 ***-1 was successfully applied to 2,4-DCA were *** -1, respectively. Our method the determination of aniline compounds in fiver water sample with high precision and accuracy.

AIM: To investigate risk factors for development of hepatocellular carcinoma(HCC) in patients with hepatitis C virus-related liver cirrhosis(LC-C).METHODS: To evaluate the relationship between clinical factors including virological response and the development of HCC in patients with LC-C treated with interferon(IFN) and ribavirin, we conducted a multicenter, retrospective study in 14 hospitals in Japan. All patients had compensated LC-C with clinical or histological data available. HCC was diagnosed by the presence of typical hypervascular characteristics on computed tomography and/or magnetic resonance ***: HCC was diagnosis in 50(21.6%) of 231 LC-C patients during a median observation period of 3.8 years after IFN and ribavirin therapy. Patients who developed HCC were older(P = 0.018) and had higher serum levels of pretreatment alpha-fetoprotein(AFP)(P = 0.038). Multivariate analysis revealed the following independent risk factors for HCC development: history of treatment for HCC [P < 0.001, odds ratio(OR) = 15.27, 95%CI: 4.98-59.51], AFP levels of ≥ 10 ng/m L(P = 0.009, OR = 3.89, 95%CI: 1.38-11.94), and des-γ-carboxy prothrombin(DCP) levels of ≥ 40 m AU/mL at 24 wk after the completion of IFN and ribavirin therapy(P < 0.001, OR = 24.43, 95%CI: 4.11-238.67).CONCLUSION: We suggested that the elevation of AFP and DCP levels at 24 wk after the completion of IFN and ribavirin therapy were strongly associated with the incidence of HCC irrespective of virological response among Japanese LC-C patients.
