Abstract
Alcoholic fatty liver disease (AFLD) is the result of an excessive or chronic consumption of alcohol. Nine male Wistar rats per group were randomly assigned to one of the following drinking treatments: a 20% (w/w) alcohol solution (ALC); a 20% (w/w) alcohol solution cotreated with 0.25 g silymarin/kg...

Abstract
The lacLM genes from Lactobacillus sakei Lb790, encoding a heterodimeric β-galactosidase that belongs to glycoside hydrolase family GH2, were cloned and heterologously expressed in Escherichia coli . Subsequently, the recombinant β-galactosidase LacLM was purified to apparent homogeneity and charac...

Abstract
We demonstrate a novel method for by-design placement of nano-objects along double-stranded (ds) DNA. A molecular intercalator, designed as a peptide nucleic acid (PNA)-DNA chimera, is able to invade dsDNA at the PNA-side due to the hybridization specificity between PNA and one of the duplex strands...

Abstract
We provided molecular evidence associated with the antimetastatic effect of green tea polyphenol epigallocatechin-3 gallate (EGCG) in an oral squamous cell culture system by showing a nearly complete inhibition on the invasion (P...

Abstract
The variations in glucosidic linkage specificity observed in products of different glucansucrases appear to be based on relatively small differences in amino acid sequences in their sugar-binding acceptor subsites. Various amino acid mutations near active sites of DSRBCB4 dextransucrase from Leuconos...

Abstract
To develop safe and cheap thrombolytic agents, a fibrinolytic enzyme productive strain of LSSE-62 was isolated from Chinese soybean paste. This strain was identified as Bacillus amyloliquefaciens by 16S rDNA sequence analysis. Nucleotide and amino acid sequence analysis showed that this fibrinolytic...

Abstract
A novel gene (designated as tan410) encoding tannase was isolated from a cotton field metagenomic library by functional screening. Sequence analysis revealed that tan410 encoded a protein of 521 amino acids. SDS-PAGE and gel filtration chromatography analysis of purified tannase suggested that Tan410...

Abstract
The aim of this study was to investigate the effect of conjugated linoleic acids (CLAs) on macrophage reactive oxygen species synthesis and the activity and expression of antioxidant enzymes, catalase (Cat), glutathione peroxidase (GPx), and superoxide dismutase (SOD). The macrophages were obtained f...

Abstract
We carried out kinetic analysis of a miRNA's turnover following termination of its biogenesis and during regulation of a target that is not subject to Ago2-mediated catalytic cleavage. By quantitating the number of molecules of the miRNA and its target in steady state and in the course of its decay,...

Abstract
We provide a practical guide for design and assembly of scaffolded DNA origami objects. We also introduce a computational tool for predicting the structure of DNA origami objects and provide information on the conditions under which DNA origami objects can be expected to maintain their structure....

Abstract
Hyperoxaluria is a major problem causing nephrolithiasis. Little is known about the regulation of oxalate transport from the liver, the main organ for oxalate synthesis, into the circulation. Since the sulfate anion transporter-1(sat-1) is present in the sinusoidal membrane of hepato...

Abstract
We have mutated the glutamines at 713 and 1375 to asparagine, methionine or leucine to determine the functional roles of these residues in Q-loops of MRP1. All these single mutants significantly decreased Mg·ATP binding and increased the K(m) (Mg·ATP) and V(max) values in Mg·ATP-dependent leukotr...

Abstract
Stem cell-based tissue engineering has provided an alternative strategy to treat cartilage lesions, and synovium-derived mesenchymal stem cells (SMSCs) are considered as a promising cell source for cartilage repair. In this study, the SMSCs were isolated from rat synovium, and CD105-...

Abstract
We provide a protocol for a sequence-independent approach for cloning complex individual or combinatorial DNA libraries, and routine or high-throughput cloning of single or multiple DNA fragments. The strategy, called circular polymerase extension cloning (CPEC), is based on polymerase overlap exten...

Abstract
We demonstrated the viability of the primers and the protocols, by compiling a full Dinornis microsatellite dataset representing fossils of c. 600-5000 years of age. A multi-locus genotype was obtained from 74 individuals (84% success rate), and the data showed no signs of being compromised by allel...

Abstract
We used the fluorescence-labeled methylation-sensitive amplified polymorphism (F-MSAP) method to assess the extent and pattern of cytosine methylation in muscle, heart, liver, spleen, lung, kidney and stomach from the swine strain Laiwu, and we also examined specific methylation patterns in the seve...

Abstract
We have developed a strategy for rapid and combinatorial optimization of the hot spot residues of enzymes. After combinatorial randomization of target locations in the Candida antarctica lipase B (CalB) gene, the individual variant genes isolated in the E.coli cells were expressed in the cell-free p...

Abstract
We characterise the sPLA2 IB gene in Atlantic cod (Gadus morhua) and describe its ontogeny at the genetic and protein level and compare this to the total sPLA2 activity level. A positive correlation was found between the expression of sPLA2 IB mRNA and protein. Both remained stable and low during th...

Abstract
We tested curcumin for its ability to induce PON1 in Huh7 hepatocytes in culture. Curcumin ( ≥ 10 μmol/l) dose-dependently induced PON1 transactivation in Huh7 cells. However, dietary supplementation of female B6C3F1 mice with curcumin (500 mg/kg diet) for 2 weeks did not increase the hepatic PON...

We hypothesised that dietary OF has also an inhibitory influence on atherosclerosis development. To verify our hypothesis, we investigated the effect of feeding diets containing an OF (a 92 : 8 mixture of heated (170°C, 48 h) hydrogenated palm fat and fresh sunflower oil) compared with a fresh fat...
