Tough, Freeze-Resistant, Pressure-Response Gel Polymer Electrolytes with Redox Pairs for Flexible Supercapacitors.

Gel polymer electrolytes are an indispensable part of flexible supercapacitors, since their various characteristics determine the device performance. Here, a composite gel electrolyte (FLPS) mainly consisting of polyvinyl alcohol (PVA), sodium alginate (SA), KFe(CN)/KFe(CN), and LiCl is rationally designed, in which PVA and SA form a robust three-dimensional network, the redox pair of KFe(CN)/KFe(CN) serves as a cross-linking agent with SA and even donates the oxidation-reduction reaction from the Fe/Fe couple with additional capacitance for the device, and LiCl functions as an ion carrier and a water-retaining salt to improve the long-term stability of FLPS. Thus, the FLPS-based supercapacitor exhibits superior electrochemical characteristics, displaying impressive pseudocapacitance across all current densities and excellent cycling stability (∼99.

Entropy and crystal-facet modulation of P2-type layered cathodes for long-lasting sodium-based batteries.

P2-type sodium manganese-rich layered oxides are promising cathode candidates for sodium-based batteries because of their appealing cost-effective and capacity features. However, the structural distortion and cationic rearrangement induced by irreversible phase transition and anionic redox reaction at high cell voltage (i.e.

Association between X-ray repair cross-complementing group 1 Arg194Trp polymorphism and colorectal cancer risk.

The polymorphism of X-ray repair cross-complementing group 1 (XRCC1) Arg194Trp, a substitution of Arg to Gln at position 194, has been implicated in the development of colorectal cancer (CRC) in a number of case-control studies with contradictory and inconclusive findings. The current meta-analysis of all currently available publications was conducted to assess the gene susceptibility to CRC and improve our understanding of the CRC pathogenesis. The pooled odds ratio (OR) with corresponding 95 % confidence interval (95 % CI) was calculated by use of fixed-effects model or random-effects model when appropriate.

Isoliquiritigenin showed strong inhibitory effects towards multiple UDP-glucuronosyltransferase (UGT) isoform-catalyzed 4-methylumbelliferone (4-MU) glucuronidation.

Isoliquiritigenin, a herbal ingredient with chalcone structure, has been speculated to be able to inhibit one of the most drug-metabolizing enzymes (DMEs) UDP-glucuronosyltransferase (UGT). Therefore, the aim of the present study was to investigate the inhibition of isoliquiritigenin towards important UGT isoforms in the liver and intestine, including UGT1A1, 1A3, 1A6, 1A7, 1A8, 1A9 and 1A10. The recombinant UGT-catalyzed 4-methylumbelliferone (4-MU) glucuronidation was used as probe reactions.

[Protective effect of Salvia on ischemia-reperfusion hepatic injury in rats].

Objective: To detect the expressions of nuclear factor-Kappa B (NF-κB) and intercellular adhesion molecule-1 (ICAM-1) after hepatic ischemia-reperfusion injury so as to study the protective effect of Salvia in rats.

Methods: The hepatic ischemia-reperfusion rat model was established by the method of Nauta. The rats were randomly divided into 3 groups: sham operation (S), ischemia-reperfusion (I/R) and Salvia preconditioning (P).
