OBJECTIVES Type 2 diabetes mellitus (T2DM) is associated with circadian disruption. Our previous experimental results have showed that dietary Lycium barbarum. polysaccharide (LBP-4a) exhibited hypoglycemic and improving insulin resistance (IR) activities. This study was to explore the mechanisms of LBP-4a for improving hyperglycemia and IR by regulating biological rhythms in T2DM rats. MATER...

The synthesis and pharmacological characterization of a series of N-substituted 3-(4-fluorophenyl)tropane derivatives is reported. The compounds displayed binding characteristics that paralleled those of cocaine, and several had substantially higher affinity at cocaine recognition sites. Conjugate addition of 4-fluorophenyl magnesium bromide to anhydroecgonine methyl ester gave 2 beta-(carbomet...

Efficient in vitro systems to study the life cycle of hepatitis C virus (HCV) were recently developed for JFH1 (genotype 2a), which has unique replication capacity in Huh7 cells. We developed 4a/JFH1 intergenotypic recombinants containing the structural genes (Core, E1, and E2), p7, and all or part of NS2 of the 4a prototype strain ED43 that, after transfection of Huh7.5 cells with RNA transcri...

In this study, we show that at least one lethal mutation at the 3F-4A region of the X chromosome can generate an array of chromosome rearrangements, all with one chromosome break in the 3F-4A region. The mutation at 3F-4A (secondary mutation) was detected in an X chromosome carrying a reverse mutation of an unstable lethal mutation, which was mapped in the 6F1-2 doublet (primary mutation). The ...

Eukaryotic initiation factor 4A (eIF-4A) is an essential component for protein translation in eukaryotes. The eIF-4A gene (ApeIF-4A) was isolated and characterized from Antheraea pernyi (Guérin-Méneville) (Lepidoptera: Saturniidae). The obtained cDNA sequence was 1,435-bp long with an open reading frame of 1,266 bp encoding 421 amino acids. The predicted amino acid sequence shared several conse...

The aim was to assess the relationship between eNOS 4a/b and -786T/C polymorphisms with coronary artery disease (CAD), obesity and diabetes mellitus. Total number of 1313 patients underwent coronary angiography, 939 had significant CAD (stenosis of > or = 1 coronary artery > or = 50%), 222 had smooth coronary arteries. Patients with insignificant atherosclerosis were excluded, the study finally...

The enantiomerically enriched γ- and δ-decalactones (4a and 4b) were prepared from corresponding racemic primary-secondary 1,4- and 1,5-diols (1a and 1b), as products of enzymatic oxidation catalyzed by different alcohol dehydrogenases. The results of biotransformations indicated that the oxidation processes catalyzed by alcohol dehydrogenase (HLADH), both isolated from horse liver and recombin...
