A direct competitive enzyme-linked immunosorbent assay (dc-ELISA) and an immunosensor based on surface plasmon resonance (SPR-sensor) were developed for fungicide boscalid determination in horticultural crops. To produce antiboscalid monoclonal antibodies (MoAb BSC7 and MoAb BSC72) for these assays, a hapten of boscalid was synthesized and conjugated to keyhole limpet hemocyanin for Balb/c mouse immunization. The working range of the dc-ELISA was 0.8-16 ng/mL with MoAb BSC7 and 2.5-120 ng/mL with MoAb BSC72, and that of the SPR-sensor was 17-80 ng/mL with MoAb BSC7. The dc-ELISA and SPR-sensor were compared for their sensitivity in determining boscalid residues at the maximum residue limit of 1-40 mg/kg for horticultural crops in Japan. Recovery of the spiked boscalid was 85-109% by the SPR-sensor and 100-124% by the dc-ELISA. On real tomato samples, the results obtained by both of these immunoassays correlated well with the results obtained by high-performance liquid chromatography.

This study aimed to evaluate the real world efficacy and safety of 12 week sofosbuvir/velpatasvir (SOF/VEL) treatment for patients with decompensated liver cirrhosis caused by hepatitis C virus (HCV) infection. Methods: A total 72 of patients with Child-Pugh (CP) class B or C were enrolled. We evaluated the sustained virologic response at 12 weeks after the end of treatment (SVR12), adverse events (AEs), and changes in the liver function. Results: All participants had genotype 1 or 2 HCV infection. At baseline, the numbers of patients with CP class B and C were 59 and 13, respectively. The overall SVR12 rate was 95.8% (69/72); 94.9% (56/59) in CP class B and 100% (13/13) in CP class C. The serum albumin level, prothrombin time and ascites were significantly improved (P<0.01); however, the serum bilirubin level and encephalopathy did not improve. Among patients who achieved SVR12, 75.0% showed an improvement in their CP score, while 5.9% showed a worsening. The presence of large portosystemic shunt (diameter ≥6 mm) and hyperbilirubinemia (≥2.0 mg/dL) were independent factors that interfered with the improvement in the CP score (P<0.

These results indicate that HAV isolates belonging to the IA-2 lineage might have been imported from the Philippines.

The effect of argon ion implantation has been studied in the Bi,Sr,CaCu,O, bulk high-T, superconducting system. The incident energy has been kept at 150 keV and the irradiation dose varied between 1 x IO" ions/cm2 and 1 x IO'= ions/cm'. It has been observed that the transition temperature does not change appreciably up to a dose of 1 x IO'=' ions/cm2. The variation of normal state resistance with ion dose shows a weak oscillatory nature which is also reflected in the variation of the c-axis parameter as determined by x-ray diffraction studies. The results are discussed in t h e light of the role of defect creation bearing in mind the similarity of the sizes of t h e Ar ions and Ca atoms in the superconducting system. It is proposed that due to this similarity between the two species, the defects created do not alter the properties very drastically, in contrast to the case of Ne and N implantation.
