This article describes a local error estimator for Glimm＇s scheme for hyperbolic systems of conservation laws and uses it to replace the usual random choice in Glimm＇s scheme by an optimal choice. As a by-product of the local error estimator, the procedure provides a global error estimator that is shown numerically to be a very accurate estimate of the error in l1 （R） for all times. Although there is partial mathematical evidence for the error estimator proposed, at this stage the error estimator must be considered ad- hoc. Nonetheless, the error estimator is simple to compute, relatively inexpensive, without adjustable parameters and at least as accurate as other existing error estimators. Numerical experiments in 1-D for Burgers＇ equation and for Euler＇s system are performed to measure the asymptotic accuracy of the resulting scheme and of the error estimator.

为探究温度变化对岩扇贝Crassadoma gigantea幼贝(壳长为36.39 mm±4.45 mm)抗氧化系统的响应,试验从低温开始每天1℃逐渐升温,共设5、10、15、20、25℃5个温度试验组,检测温度胁迫下各组岩扇贝幼贝鳃组织抗氧化酶活力(超氧化物歧化酶SOD、过氧化氢酶CAT活性和总抗氧化能力T-AOC)的变化。结果表明:岩扇贝幼贝SOD活力在5℃时显著低于其他温度组(P0.05);CAT活力在温度5~20℃时各组间无显著性差异(P>0.05),在25℃时显著高于其他温度组(P<0.05);T-AOC能力在15℃时显著高于其他温度组(P<0.05),温度从15℃升高或降低,T-AOC能力都会显著下降(P<0.05),温度从15℃降低至5℃时,T-AOC能力的下降幅度显著高于温度从15℃升高至25℃时的下降幅度(P<0.05)。研究表明,高温对岩扇贝幼贝鳃组织中CAT活力有着明显的诱导作用,对T-AOC能力有着明显的抑制作用,低温对岩扇贝幼贝组织中SOD活力、T-AOC能力有着明显的抑制作用,从抗氧化酶活力的变化证明了15℃为岩扇贝幼贝最适生长水温。

The role of S-layer proteins (SlP)， which form the outermost layer of cell walls in lactic acid bacteria (lAB)， plays a crucial role in regulating immune-stimulating activity， thereby closely influencing lAB's ability to boost host immunity. In this study， the heterologous expression， purification， and characterization of l. acidophilus CICC6074-derived slpX protein and the molecular mechanism of its anti-inflammatory effect on lPS-induced RAW264.7 cells were investigated. Initially， the PCR results were shown to successfully clone the slpX DNA sequence by homologous recombination to obtain the pet-32a-slpX recombinant plasmid. SDS-PAGE results revealed that slpX protein with a molecular weight of 54 kDa was successfully obtained under 0.7 mmol/l IPTG-induced conditions， which was further demonstrated by western blot(WB) and lC-MS/MS. ElISA， WB and molecular docking results indicated that slpX protein can inhibit lPS-induced cellular inflammatory responses by linking to TlR4 and MD2 via hydrogen bonding and increasing the levels of anti-inflammatory factor Il-10 and decreasing the levels of inflammatory factors (TNF-α， Il-6， NO) and ROS via MAPK and NF-κB signaling pathways. The study is essential for the preparation of pure slpX protein and revealing its anti-inflammatory molecular mechanism.
