Abstract

Background: Biliary atresia (BA) is among the commonest indications for liver transplantation (LT) in children. We examined whether serum matrix metalloproteinase‐7 (MMP‐7) is useful for diagnosis of BA in Japanese infants, and whether serum MMP‐7 concentrations before and after Kasai portoenterostomy (KP) predicted LT within a year. Methods: Subjects under 6 months old at eight pediatric centers in Japan were enrolled retrospectively, including patients with cholestasis and normal controls (NC) without liver disease. Patients with cholestasis were divided into groups representing BA versus cholestasis from other causes (non‐BA). Serum samples were collected from patients with BA at diagnosis and 1 and 4 weeks after KP, as well as from non‐BA and NC. Results: Serum MMP‐7 concentrations were significantly higher in BA at diagnosis (median, 89.1 ng/ml) than in non‐BA (11.0; p < 0.001) or NC (10.3; p < 0.001). Receiver operating characteristic (ROC) analysis of MMP‐7 for BA versus non‐BA yielded an area under the ROC curve of 0.99 (95% confidence interval, 0.96–1.00). An optimal cut‐off value of 18.6 ng/ml for serum MMP‐7 in diagnosing BA demonstrated sensitivity and specificity of 100% and 90%, respectively. Serum MMP‐7 before and 1 week and 4 weeks after KP did not differ significantly between BA requiring only KP and BA requiring LT after KP. Conclusion: Serum MMP‐7 is a useful marker for diagnosis of BA in Japanese infants, but it could not predict LT within a year. [ABSTRACT FROM AUTHOR]

23. Rheological properties of concentrated solutions of agarose in ionic liquid.

Abstract

The rheological properties of agarose solutions were examined under the effect of entanglement coupling between agarose chains. Agarose solutions were prepared by using an ionic liquid 1-butyl-3-methylimidazolium chloride as a solvent. The concentration of agarose was varied from 1.1 × 101-2.1 × 102 kg m−3. The master curves of the angular frequency (ω) dependence of the storage modulus ( G′) and the loss modulus ( G″) showed a rubbery region in the middle ω region and a flow region at low ω region, respectively. The molecular weight between entanglements ( M e) for agarose was calculated from the plateau modulus. Moreover, M e for agarose melt was determined to be 2.3 × 103 from the concentration dependence curve of M e. By using well-known empirical relations in polymer rheology, information on molecular characteristics of sample agarose was derived. © 2011 Wiley Periodicals, Inc.
