Role of social media to improve job performance with mediating role of transactive memory capability and employee creativity.

The increased usage of social media in organizational settings has raised questions about its effect on job performance. This study explains the interplay between social media usage, transactive memory capability, employee creativity, and job performance within the Chinese organizational context. The rationale for this study stems from the need to understand how social media usage can enhance job performance through cognitive and creative processes within teams.

Sulforaphane suppresses cell proliferation and induces apoptosis in glioma via the ACTL6A/PGK1 axis.

This study aimed to examine the expression and biological functions of ACTL6A in glioma cells (U251), the effects of sulforaphane on the growth of U251 cells and the involvement of the ACTL6A/PGK1 pathway in those effects. The U251 cell line was transfected with ACTL6A over-expression plasmids to upregulate the protein, or with ACTL6A inhibitor to underexpress it, then treated with different concentrations of sulforaphane. Cell viability, proliferation, and apoptosis were assessed using standard assays, and levels of mRNAs encoding ACTL6A, PGK1, cyclin D1, Myc, Bax or Bcl-2 were measured using quantitative real-time polymerase chain reaction (qRT-PCR).

Microfluidic Liver-on-a-Chip for Preclinical Drug Discovery.

Drug discovery is an expensive, long, and complex process, usually with a high degree of uncertainty. In order to improve the efficiency of drug development, effective methods are demanded to screen lead molecules and eliminate toxic compounds in the preclinical pipeline. Drug metabolism is crucial in determining the efficacy and potential side effects, mainly in the liver.

Obtaining help by standing higher: The mediating role of moral reputation.

Drawing on the social cognitive chain of being (SCCB) theory and heuristic perspective, the present study explored whether and how social targets' vertical spatial position influences the help the social targets can get from others. Study 1 demonstrated that individuals would be more likely to help social targets who were presented on a higher vertical spatial position than those who were presented on a lower vertical spatial position. In Study 2, an experimental-causal-chain design was adopted for further testing the mediating role of moral reputation between the social targets' vertical spatial position and the amount of help that the social targets obtain from others.

Escherichia coli PagP Enzyme-Based De Novo Design and In Vitro Activity of Antibacterial Peptide LL-37.

BACKGROUND The aim of this study was to investigate the antimicrobial property of peptide LL-37 sequences. MATERIAL AND METHODS Humanized antibacterial peptide LL-37 and the mutant were prepared by chemical synthesis. The physicochemical properties of antibacterial peptide LL-37 were analyzed by SWISS-MODEL online prediction tool.

Thermosensitive AB4 four-armed star PNIPAM-b-HTPB multiblock copolymer micelles for camptothecin drug release.

Thermo-sensitive poly(N-isoproplacrylamide)m-block-hydroxyl-terminated polybutadiene-block-poly(N-isoproplacrylamide)m (PNIPAMm-b-HTPB-b-PNIPAMm, m = 1 or 2) block copolymers, AB4 four-armed star multiblock and linear triblock copolymers, were synthesized by ATRP with HTPB as central blocks, and characterization was performed by (1)H NMR, Fourier transform infrared, and size exclusion chromatography. The multiblock copolymers could spontaneously assemble into more regular spherical core-shell nanoscale micelles than the linear triblock copolymer. The physicochemical properties were detected by a surface tension, nanoparticle analyzer, transmission electron microscope (TEM), dynamic light scattering, and UV-vis measurements.
